Definitions
- the present invention relates to a load-break switch device and/or a switch fuse device for accommodating at least one fuse or one fuse plug for such a fuse.
- the present invention relates in particular to three-pole systems, optionally with an additional N pole.
- Such devices are particularly suitable for fastening and connecting electrical devices, for example installation devices, in particular by means of a so-called top-hat rail or by means of busbar systems.
- Another system is from the EP 3 016 122 A1 known, which discloses a circuit breaker device or switch fuse device for accommodating at least one fuse or a fuse plug for a fuse, the circuit breaker device comprising a coil on each of the fuses and the circuit breaker device for each fuse comprising a foot contact and a head contact within the housing.
- a device (load-break switch device or switch fuse device) according to the present invention comprises a housing and at least one input terminal for connection to a power supply and at least one output terminal for connection to at least one electrical device.
- the device according to the invention also comprises a foot contact and a head contact within the housing for each fuse, which are designed such that they can be brought into contact with an associated foot contact and an associated head contact of the fuse when the fuse is inserted and in the operating state. It is preferably a three-pole device, so that the device is designed in such a way that it can accommodate a total of three fuses, individual foot contacts and head contacts then also being provided for each of the fuses, ie a total of three foot contacts and three head contacts.
- the head contact of the device according to the invention is provided in a fuse plug into which a fuse can be inserted, so that the fuse plug with the fuse can then be inserted into the housing of the device according to the invention.
- the head contact of the fuse plug and the device are designed in such a way that the head contact of the fuse plug is in electrical contact with an associated contact of the device when the fuse plug is in its operating position.
- the foot contact of the load-break switch device or the switch fuse device is designed to be planar, at least in a partial area, or is designed in such a way that it has a flat or essentially flat surface, which is oriented in the direction of a foot contact of a fuse to be inserted, the foot contact of the device being inside
- This partial area has an elevation which extends in the direction of the foot contact of a fuse to be inserted and which, with its area facing the foot contact of the fuse, can be brought directly or indirectly into electrical contact with the foot contact of the fuse.
- the device of the present invention also comprises a Rogowski coil on each of its foot contacts, which has an opening, in particular a central opening, which at least partially surrounds the elevation of the foot contact.
- the device also includes a device for capacitive voltage measurement, preferably for each individual phase (for each individual pole), so that a current and/or voltage measurement can also be carried out reliably for each phase.
- this avoids having to provide current measuring devices on the individual electrical devices, in particular on the installation devices, so that such a device enables increased flexibility when using the electrical devices, because in principle all devices, regardless of whether they allow current measurement or not, can be connected to the device without sacrificing useful information regarding the overall system.
- a particular advantage is achieved by the special design of the foot contact of the device and the arrangement of the Rogowski coil: the elevation of the foot contact, which is located in the planar or flat sub-area of the foot contact of the device, interacts with the central opening of the Rogowski coil in such a way that safe and reliable positioning is made possible, and the manufacturing process is simplified, which leads to a reduction in costs.
- Another advantage of the inventive design of the foot contact of the device according to the present invention and the associated Rogowski coil is that the Rogowski coil is arranged in the housing in a particularly space-saving manner, which is of great importance since the size of the housing is subject to certain restrictions and must be kept as small as possible should.
- a fuse needs heat to switch off in the event of an overcurrent so that the fusible conductor melts. For this reason, depending on the load on the device, a fuse produces heat that occurs in the case.
- the special arrangement of the foot contact and the Rogowski coil, as defined in this invention, means that this air flow can be maintained despite the additional component, in particular the additional Rogowski coil having a plane that is parallel or substantially parallel to the prevailing air flow runs so that it is only negatively influenced to a very small extent.
- the heating of the device is an effect that must be carefully considered in order to avoid overheating. Since, as mentioned above, the housing should be largely closed, and active cooling devices, such as fans, require additional expenditure, both spatial and financial, and should therefore be avoided, the arrangement of the individual components in a device according to present invention is very important, especially when an essentially plate-shaped element such as a Rogowski coil is also installed.
- a device according to the present invention not only has the advantage that the systems in which such devices are used can be better monitored and thus controlled, but at the same time it ensures that the costs are kept low despite additional components, in particular the Case size small can be maintained, while in particular sufficient cooling can be ensured within the housing.
- the elevation of the foot contact of the device is essentially or even exactly circular in cross section, in a direction perpendicular to the direction of the elevation, with the preferably central opening of the Rogowski coil having an inner contour that resembles the is adapted substantially circular outer contour of the foot contact.
- a different cross-sectional shape for the elevation or the opening of the Rogowski coil for example an oval or else a square opening. It is also possible, for example, in a preferred embodiment, to provide a projection or a groove at one or more points around the circumference of the elevation or at one or more angular positions of the opening of the Rogowski coil, which with an associated groove or a projection of the other element agrees that they can be brought into engagement with one another, so that a predetermined and fixed relative angular position between foot contact and Rogowski coil is also automatically ensured, which in particular simplifies manufacture and prevents erroneous insertion of elements.
- the plane in which the preferably plate-shaped Rogowski coil extends extends essentially perpendicularly to the longitudinal axis of a fuse to be inserted when the latter is in its operating position. This leads to a further optimization of the positioning of the necessary components and thus to a space-saving arrangement. In addition, it is reliably ensured that good electrical contact is guaranteed between the foot contact of the device on the one hand and the foot contact of a fuse to be used on the other hand.
- the thickness of the Rogowski coil is preferably less than the height of the elevation of the foot contact of the load-break switch device or the switch fuse device, the height of the Elevation of the foot contact is preferably measured from the top of the flat portion of the foot contact from which the elevation extends.
- the device is designed in such a way that it can be connected to a busbar system.
- both the flat portion of the foot contact and the plane in which the Rogowski coil extends are preferably aligned essentially parallel to a plane in which the busbars run or which is defined by the course of the busbars when the device is in its operating position connected to the busbar system. This preferred arrangement further supports the effect already described above of ensuring adequate cooling of the system.
- the device is designed in such a way that it can be mounted on a top-hat rail.
- both the planar portion of the foot contact and the plane in which the Rogowski coil extends are preferably aligned essentially parallel to a plane in which the top-hat rail runs or which is formed by the course of the top-hat rail, if the device is in its operating position, mounted on the DIN rail, which also supports the effects of sufficient cooling already described above in connection with busbar systems.
- a device according to the present invention also includes a fitting sleeve which is designed in such a way that only a fuse suitable for the device can be used. This ensures that operating errors, in particular the use of unsuitable fuses, are avoided.
- Such a fitting sleeve is preferably designed such that it includes a receiving area for part of an insertable fuse, the receiving area having a geometry, in particular an inner diameter, which is adapted to the geometry, in particular an outer diameter, of the suitable fuse.
- this ensures that no fuses can be used that could lead to an overload, in particular to overheating, of the system.
- a device according to the invention preferably further comprises a spring clip which is designed in such a way that it at least partially encompasses the base contact of the device, either a switch disconnector device or a switch fuse device, and the fitting sleeve described above. This ensures a particularly reliable positioning and a particularly reliable electrical contact during operation.
- the Rogowski coil is provided with a heat-resistant, insulating varnish. This has the advantage that a galvanic separation of the Rogowski coil, in particular from the foot contact, is ensured.
- the device is designed in such a way that the distances between the Rogowski coil and the foot contact, possibly also to other current-carrying parts, are selected such that galvanic isolation is ensured even without the heat-resistant, insulating paint described above .
- the galvanic isolation between the evaluation electronics and the live or live parts or contacts of the device is of particular importance.
- a measurement of the voltage is also required.
- the device according to the invention is also designed in such a way that the voltage is measured capacitively or galvanically separately from the contacts of the devices.
- a load-break switch device or a switch fuse device which comprises a housing and a plurality of input terminals for connection to a power supply and a plurality of output terminals for connection to at least one electrical device, the device being designed in such a way that all output terminals for connection at least one electrical device are arranged on one side of the housing, this one side extending essentially parallel to a longitudinal extent of the busbars or the top-hat rail and perpendicular to a plane which is formed by the busbars or the top-hat rail when the device is in their operating position, i.e. connected to the busbar system or mounted on the top-hat rail.

- a fuse 320 can be inserted into the device 100, with the device shown here also being provided with a fuse plug 300, into which the fuse 320 is inserted, with the fuse plug 300 with the fuse 320 then being inserted into the Housing 110 of the device 100 is used and the fuse 320 can thereby be brought into contact with the associated foot contact 160 of the device 100 .
- the device 100 according to the invention also includes a Rogowski coil 400, which serves to measure the current.
- the Rogowski coil 400 is designed as a substantially plate-shaped one Formed component having a central opening, which encloses a survey 164 of the foot contact 160 of the device 100, completely encloses in this embodiment.
- a corresponding arrangement is also implemented for all other poles of the device 100, so that each pole of the device 100 includes a Rogowski coil 400, so that a reliable current measurement is ensured for each pole of the device 100.
- a device 480 for capacitive voltage measurement which, in this embodiment, is arranged in the vicinity of the movable contact 195. This also makes it possible to carry out a reliable voltage measurement for each pole of the device, so that, together with the Rogowski coil, current and voltage measurements can be carried out safely and reliably.
- FIG 3 shows a foot contact 160, a Rogowski coil 400, a fitting 190 and a spring clip 194, as used in a device according to FIG 1 and the 2 are used, however, as they can also be used in other embodiments.
- the foot contact 160, the Rogowski coil 400 and the fitting 190 are designed and arranged so that they are close together and have a small footprint, and are also held securely by the spring clip 194 in their relative position to one another.

- the elevation 164 is essentially cylindrical, but it is also possible to choose other shapes.
- the Rogowski coil 400 is designed as a plate-shaped element that has a central opening 420 that is circular and thus adapted to the essentially cylindrical elevation 164 of the foot contact 160 of the device.
- the Rogowski coil also includes connection lines 440, via which the signals from the Rogowski coil 400 can be passed on, in particular to an evaluation unit.
- the Rogowski coil 400 is provided with a heat-resistant, insulating lacquer, so that galvanic isolation is ensured.
- the fitting sleeve 190 is also designed to be essentially cylindrical, with the inside diameter of the cylindrical interior space being designed in such a way that only suitable securing devices can be used.

Es ist eine Aufgabe der vorliegenden Erfindung, eine solche Lasttrennschaltervorrichtung und/oder eine solche Schaltersicherungsvorrichtung im Hinblick auf die Nutzerfreundlichkeit und unter Berücksichtigung der gewünschten Anwendungen weiter zu verbessern.It is an object of the present invention to further improve such a load-break switch device and/or such a switch fuse device with regard to user-friendliness and taking into account the desired applications.
Diese Aufgabe wird durch einen Lasttrennschaltervorrichtung oder eine Schaltersicherungsvorrichtung gemäß Anspruch 1 gelöst, die Ansprüche 2 bis 15 betreffen besonders vorteilhafte Ausführungsformen einer solchen Lasttrennschaltervorrichtung oder einer solchen Schaltersicherungsvorrichtung.This object is achieved by a load-break switch device or a switch fuse device according to claim 1, claims 2 to 15 relate to particularly advantageous embodiments of such a load-break switch device or such a switch fuse device.
Eine Vorrichtung (Lasttrennschaltervorrichtung oder Schaltersicherungsvorrichtung) gemäß der vorliegenden Erfindung umfasst ein Gehäuse und mindestens einen Eingangsanschluss zum Anschluss an eine Stromversorgung und mindestens einen Ausgangsanschluss zum Anschluss an mindestens ein elektrisches Gerät.A device (load-break switch device or switch fuse device) according to the present invention comprises a housing and at least one input terminal for connection to a power supply and at least one output terminal for connection to at least one electrical device.
Die erfindungsgemäße Vorrichtung umfasst ferner für jede Sicherung jeweils einen Fußkontakt und einen Kopfkontakt innerhalb des Gehäuses, die so ausgebildet sind, dass sie bei eingesetzter Sicherung und im Betriebszustand jeweils in Kontakt mit einem zugehörigen Fußkontakt und einem zugehörigen Kopfkontakt der Sicherung gebracht werden können. Bevorzugt handelt es sich um eine dreipolige Vorrichtung, sodass die Vorrichtung so ausgebildet ist, dass sie insgesamt drei Sicherungen aufnehmen kann, wobei dann auch für jede der Sicherungen jeweils einzelne Fußkontakte und Kopfkontakt, also insgesamt drei Fußkontakte und drei Kopfkontakte, vorgesehen sind.The device according to the invention also comprises a foot contact and a head contact within the housing for each fuse, which are designed such that they can be brought into contact with an associated foot contact and an associated head contact of the fuse when the fuse is inserted and in the operating state. It is preferably a three-pole device, so that the device is designed in such a way that it can accommodate a total of three fuses, individual foot contacts and head contacts then also being provided for each of the fuses, ie a total of three foot contacts and three head contacts.
Bei einer besonderen Ausführungsform ist der Kopfkontakt der erfindungsgemäßen Vorrichtung in einem Sicherungsstöpsel vorgesehen, in den eine Sicherung eingesetzt werden kann, so dass dann der Sicherungsstöpsel mit der Sicherung in das Gehäuse der erfindungsgemäßen Vorrichtung eingesetzt werden kann.In a particular embodiment, the head contact of the device according to the invention is provided in a fuse plug into which a fuse can be inserted, so that the fuse plug with the fuse can then be inserted into the housing of the device according to the invention.
Der Kopfkontakt des Sicherungsstöpsels und die Vorrichtung sind dabei so ausgebildet, dass der Kopfkontakt des Sicherungsstöpsels mit einem zugehörigen Kontakt der Vorrichtung elektrisch in Kontakt steht, wenn sich der Sicherungsstöpsel in seiner Betriebsposition befindet.The head contact of the fuse plug and the device are designed in such a way that the head contact of the fuse plug is in electrical contact with an associated contact of the device when the fuse plug is in its operating position.
Gemäß der Erfindung ist der Fußkontakt der Lasttrennschaltervorrichtung oder der Schaltersicherungsvorrichtung zumindest in einen Teilbereich eben ausgebildet oder so ausgebildet ist, dass er eine flache oder im Wesentlichen flache Oberfläche aufweist, die in Richtung eines Fußkontakts einer einzusetzenden Sicherung ausgerichtet ist, wobei der Fußkontakt der Vorrichtung innerhalb dieses Teilbereichs eine Erhebung aufweist, die sich in Richtung auf den Fußkontakt einer einzusetzenden Sicherung erstreckt und die mit ihrem dem Fußkontakt der Sicherung zugewandten Bereich direkt oder indirekt in einen elektrischen Kontakt mit dem Fußkontakt der Sicherung gebracht werden kann.According to the invention, the foot contact of the load-break switch device or the switch fuse device is designed to be planar, at least in a partial area, or is designed in such a way that it has a flat or essentially flat surface, which is oriented in the direction of a foot contact of a fuse to be inserted, the foot contact of the device being inside This partial area has an elevation which extends in the direction of the foot contact of a fuse to be inserted and which, with its area facing the foot contact of the fuse, can be brought directly or indirectly into electrical contact with the foot contact of the fuse.
Die Vorrichtung der vorliegenden Erfindung umfasst ferner an jedem ihrer Fußkontakte eine Rogowskispule, die eine Öffnung, insbesondere eine zentrale Öffnung, aufweist, die die Erhebung des Fußkontakts zumindest teilweise umgreift.The device of the present invention also comprises a Rogowski coil on each of its foot contacts, which has an opening, in particular a central opening, which at least partially surrounds the elevation of the foot contact.
Dies hat den Vorteil, dass bereits in der Vorrichtung, einer Lasttrennschaltervorrichtung oder einer Schaltersicherungsvorrichtung, direkt und für jeden Pol bzw. für jede Phase eine Strommessung erfolgen kann. Eine Strommessung kann daher, völlig unabhängig von den anzuschließenden elektrischen Geräten, erfolgen, so dass für jede einzelne Phase (für jeden einzelnen Pol) eine zuverlässige Messung sichergestellt werden kann.This has the advantage that a current measurement can already be carried out directly and for each pole or for each phase in the device, a switch disconnector device or a switch fuse device. A current measurement can therefore, completely independently of the electrical devices to be connected, so that a reliable measurement can be ensured for each individual phase (for each individual pole).
Bei einer weiteren bevorzugten Ausführungsform umfasst die Vorrichtung ferner eine Vorrichtung zur kapazitiven Spannungsmessung, bevorzugt für jede einzelne Phase (für jeden einzelnen Pol), so dass auch zuverlässig für jede Phase eine Strom- und/oder Spannungsmessung erfolgen kann.In a further preferred embodiment, the device also includes a device for capacitive voltage measurement, preferably for each individual phase (for each individual pole), so that a current and/or voltage measurement can also be carried out reliably for each phase.
Für den Nutzer bzw. Betreiber hat dies den Vorteil, dass er an dieser zentralen Stelle alle relevanten Informationen über das angeschlossene System erhalten kann, insbesondere direkt Rückschlüsse auf den Betrieb des Systems, den Stromverbrauch sowie Änderungen während des Betriebs ziehen kann, die für den Betrieb oder die Überwachung des Systems von Bedeutung sind.For the user or operator, this has the advantage that he can obtain all relevant information about the connected system at this central point, in particular he can directly draw conclusions about the operation of the system, the power consumption and changes during operation that are necessary for the operation or the monitoring of the system are important.
Insbesondere wird dadurch vermieden, dass Strommessvorrichtungen an den einzelnen elektrischen Geräten, insbesondere an den Installationsgeräten, vorgesehen sein müssen, so dass eine solche Vorrichtung eine erhöhte Flexibilität beim Einsatz der elektrischen Geräte ermöglicht, weil grundsätzlich alle Geräte, unabhängig davon, ob sie eine Strommessung erlauben oder nicht, an die Vorrichtung angeschlossen werden können, ohne auf die hilfreichen Informationen im Hinblick auf das Gesamtsystem verzichten zu müssen.In particular, this avoids having to provide current measuring devices on the individual electrical devices, in particular on the installation devices, so that such a device enables increased flexibility when using the electrical devices, because in principle all devices, regardless of whether they allow current measurement or not, can be connected to the device without sacrificing useful information regarding the overall system.
Ein besonderer Vorteil wird durch die besondere Ausgestaltung des Fußkontakts der Vorrichtung und die Anordnung der Rogowskispule erzielt: die Erhebung des Fußkontakts, die sich in dem ebenen oder flach ausgebildeten Teilbereich des Fußkontakts der Vorrichtung befindet, wirkt so mit der zentralen Öffnung der Rogowskispule zusammen, dass eine sichere und zuverlässige Positionierung ermöglicht wird, ferner das Herstellungsverfahren vereinfacht wird, was zu einer Kostenreduktion führt.A particular advantage is achieved by the special design of the foot contact of the device and the arrangement of the Rogowski coil: the elevation of the foot contact, which is located in the planar or flat sub-area of the foot contact of the device, interacts with the central opening of the Rogowski coil in such a way that safe and reliable positioning is made possible, and the manufacturing process is simplified, which leads to a reduction in costs.
Ein weiterer Vorteil der erfindungsgemäßen Ausgestaltung des Fußkontakts der Vorrichtung gemäß der vorliegenden Erfindung und der zugehörigen Rogowskispule ist, dass die Rogowskispule besonders platzsparend in dem Gehäuse angeordnet ist, was von großer Bedeutung ist, da die Größe des Gehäuses bestimmten Beschränkungen unterliegt und möglichst klein gehalten werden soll.Another advantage of the inventive design of the foot contact of the device according to the present invention and the associated Rogowski coil is that the Rogowski coil is arranged in the housing in a particularly space-saving manner, which is of great importance since the size of the housing is subject to certain restrictions and must be kept as small as possible should.
Ein besonderer Vorteil, der sich herausgestellt hat, ist auch, dass durch diese besondere Ausgestaltung der Fußkontakte und der Rogowskispulen eine besonders gute Kühlung der Vorrichtung sichergestellt ist. Hierbei ist zu beachten, dass das Gehäuse weitgehend geschlossen ist, so dass eine Berührung der stromführenden Teile durch den Benutzer vermieden wird, so dass eine Luftströmung, die zur Kühlung dient, insbesondere zwischen den Eingangskontakten und den Ausgangskontakten zustande kommt.A particular advantage that has been found is that this special design of the foot contacts and the Rogowski coils particularly good cooling device is ensured. It should be noted here that the housing is largely closed, so that the user is prevented from touching the current-carrying parts, so that an air flow, which is used for cooling, comes about in particular between the input contacts and the output contacts.
In diesem Zusammenhang muss beachtet werden, dass eine Sicherung zum Abschalten bei einem Überstrom Wärme benötigt, damit der Schmelzleiter durchschmilzt. Aus diesem Grund produziert eine Sicherung je nach Belastung der Vorrichtung Wärme, die in dem Gehäuse auftritt.In this context, it must be noted that a fuse needs heat to switch off in the event of an overcurrent so that the fusible conductor melts. For this reason, depending on the load on the device, a fuse produces heat that occurs in the case.
Der einzige oder zumindest wesentliche, insbesondere durch thermische Effekte, erzielte Luftstrom, tritt insbesondere an der Eingangsseite ein (bei den Klemmen, dem Schalter und dem Fußkontakt) und umströmt den Sicherungseinsatz dort, wo es möglich ist, und tritt am Ausgang (insbesondere beim Kopfkontakt und bei den Klemmen) aus.The only, or at least significant, air flow, achieved in particular by thermal effects, enters in particular on the input side (at the terminals, the switch and the foot contact) and flows around the fuse-link where possible and exits at the output (especially at the head contact and at the terminals).
Die besondere Anordnung des Fußkontakts und der Rogowskispule, wie sie in dieser Erfindung definiert ist, führt dazu, dass diese Luftströmung trotz des zusätzlichen Bauelements aufrecht erhalten werden kann, wobei insbesondere die zusätzliche Rogowskispule eine Ebene aufweist, die parallel oder im Wesentlichen parallel zur vorherrschenden Luftströmung verläuft, sodass diese nur in sehr geringem Maße negativ beeinflusst wird.The special arrangement of the foot contact and the Rogowski coil, as defined in this invention, means that this air flow can be maintained despite the additional component, in particular the additional Rogowski coil having a plane that is parallel or substantially parallel to the prevailing air flow runs so that it is only negatively influenced to a very small extent.
Da an eine Vorrichtung gemäß der Erfindung elektrische Geräte mit großen Leistungen angeschlossen werden, ist die Erwärmung der Vorrichtung ein Effekt, der sorgsam beachtet werden muss, um Überhitzungen zu vermeiden. Da, wie oben erwähnt, die Gehäuse weitgehend abgeschlossen sein sollten, ferner aktive Kühlungsvorrichtungen, wie zum Beispiel Ventilatoren, zusätzlichen Aufwand, sowohl räumlicher als auch finanzieller Natur, erfordern und damit vermieden werden sollen, ist die Anordnung der einzelnen Bauteile in einer Vorrichtung gemäß der vorliegenden Erfindung sehr wichtig, insbesondere wenn zusätzlich ein im wesentlichen plattenförmiges Element wie eine Rogowskispule verbaut ist.Since electrical devices with high powers are connected to a device according to the invention, the heating of the device is an effect that must be carefully considered in order to avoid overheating. Since, as mentioned above, the housing should be largely closed, and active cooling devices, such as fans, require additional expenditure, both spatial and financial, and should therefore be avoided, the arrangement of the individual components in a device according to present invention is very important, especially when an essentially plate-shaped element such as a Rogowski coil is also installed.
Eine Vorrichtung gemäß der vorliegenden Erfindung hat damit nicht nur den Vorteil, dass die Systeme, in denen solche Vorrichtungen eingesetzt werden, besser überwacht und damit gesteuert werden können, sondern sie stellt gleichzeitig sicher, dass trotz zusätzlicher Bauteile die Kosten gering gehalten werden, insbesondere die Größe des Gehäuses klein gehalten werden kann, während insbesondere eine ausreichende Kühlung innerhalb des Gehäuses sichergestellt werden kann.A device according to the present invention not only has the advantage that the systems in which such devices are used can be better monitored and thus controlled, but at the same time it ensures that the costs are kept low despite additional components, in particular the Case size small can be maintained, while in particular sufficient cooling can be ensured within the housing.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist die Erhebung des Fußkontakts der Vorrichtung im Querschnitt, in einer Richtung senkrecht zur Richtung der Erhebung, im Wesentlichen oder sogar exakt kreisförmig ausgebildet, wobei die, bevorzugt zentrale, Öffnung der Rogowskispule eine Innenkontur aufweist, die an die im wesentlichen kreisförmige Außenkontur des Fußkontakts angepasst ist.According to a particularly preferred embodiment of the invention, the elevation of the foot contact of the device is essentially or even exactly circular in cross section, in a direction perpendicular to the direction of the elevation, with the preferably central opening of the Rogowski coil having an inner contour that resembles the is adapted substantially circular outer contour of the foot contact.
Es ist aber auch möglich, eine andere Querschnittsform der Erhebung bzw. der Öffnung der Rogowskispule vorzusehen, beispielsweise eine ovale oder auch eine eckige Öffnung. Auch ist es beispielsweise bei einer bevorzugten Ausführungsform möglich, an einer oder mehreren Stellen um den Umfang der Erhebung bzw. an einer oder mehreren Winkelpositionen der Öffnung der Rogowskispule einen Vorsprung oder eine Nut vorzusehen, die mit einem zugehörigen Nut oder einem Vorsprung des anderen Elements so übereinstimmt, dass sie in Eingriff miteinander gebracht werden können, so dass auch automatisch eine vorbestimmte und festgelegte relative Winkelposition zwischen Fußkontakt und Rogowskispule sichergestellt wird, was insbesondere die Herstellung vereinfacht und ein fehlerhaftes Einsetzen von Elementen verhindert.However, it is also possible to provide a different cross-sectional shape for the elevation or the opening of the Rogowski coil, for example an oval or else a square opening. It is also possible, for example, in a preferred embodiment, to provide a projection or a groove at one or more points around the circumference of the elevation or at one or more angular positions of the opening of the Rogowski coil, which with an associated groove or a projection of the other element agrees that they can be brought into engagement with one another, so that a predetermined and fixed relative angular position between foot contact and Rogowski coil is also automatically ensured, which in particular simplifies manufacture and prevents erroneous insertion of elements.
Diese Merkmale sorgen für eine besonders sichere und genaue Positionierung, wobei für diese Positionierung keine oder kaum weitere zusätzliche Bauteile erforderlich sind, was wiederrum auch die Herstellung vereinfacht.These features ensure particularly reliable and precise positioning, with no or hardly any additional components being required for this positioning, which in turn also simplifies production.
Bevorzugt erstreckt sich die Ebene, in der sich die, bevorzugt plattenförmige, Rogowskispule erstreckt, im Wesentlichen senkrecht zur Längsachse einer einzusetzenden Sicherung, wenn sich diese in ihrer Betriebsposition befindet. Dies führt zu einer weiteren Optimierung der Positionierung der notwendigen Bauteile und damit zu einer platzsparenden Anordnung. Darüber hinaus wird zuverlässig sichergestellt, dass ein guter elektrischer Kontakt zwischen dem Fußkontakt der Vorrichtung einerseits und dem Fußkontakt einer einzusetzenden Sicherung andererseits gewährleistet ist.The plane in which the preferably plate-shaped Rogowski coil extends extends essentially perpendicularly to the longitudinal axis of a fuse to be inserted when the latter is in its operating position. This leads to a further optimization of the positioning of the necessary components and thus to a space-saving arrangement. In addition, it is reliably ensured that good electrical contact is guaranteed between the foot contact of the device on the one hand and the foot contact of a fuse to be used on the other hand.
Bevorzugt ist die Dicke der Rogowskispule, insbesondere die Dicke einer plattenförmige ausgebildeten Rogowskispule, geringer als die Höhe der Erhebung des Fußkontakts der Lasttrennschaltervorrichtung oder der Schaltersicherungsvorrichtung, wobei die Höhe der Erhebung des Fußkontakts bevorzugt von der Oberseite des eben ausgebildeten Teilbereichs des Fußkontakts, von dem aus sich die Erhebung erstreckt, gemessen wird.The thickness of the Rogowski coil, in particular the thickness of a plate-shaped Rogowski coil, is preferably less than the height of the elevation of the foot contact of the load-break switch device or the switch fuse device, the height of the Elevation of the foot contact is preferably measured from the top of the flat portion of the foot contact from which the elevation extends.
Dies hat den Vorteil, dass der zur Verfügung stehende Raum weiter optimal ausgenutzt wird, ferner die Rogowskispule so angeordnet ist, dass sie einen elektrischen Kontakt zwischen den Fußkontakten der Vorrichtung einerseits und den Fußkontakten der Sicherungen andererseits keinesfalls behindert, wobei gleichzeitig durch die unmittelbare Nähe der Rogowskispule zu den stromführenden Teilen innerhalb der Vorrichtung eine sehr exakte Messung ermöglicht wird. Zusätzlich wird hierdurch auch der oben beschriebene Kühlungseffekt weiter unterstützt.This has the advantage that the available space continues to be used optimally, and the Rogowski coil is arranged in such a way that it in no way impedes electrical contact between the foot contacts of the device on the one hand and the foot contacts of the fuses on the other hand, while at the same time the close proximity of the Rogowski coil to the live parts within the device allows a very precise measurement. In addition, this also further supports the cooling effect described above.
Gemäß einer Ausführungsform der vorliegenden Erfindung ist die Vorrichtung so ausgebildet, dass sie an ein Sammelschienensystem angeschlossen werden kann. Bevorzugt sind bei einer solchen Vorrichtung sowohl der ebene Teilbereich des Fußkontakts als auch die Ebene, in der sich die Rogowskispule erstreckt, im Wesentlichen parallel zu einer Ebene ausgerichtet, in der die Sammelschienen verlaufen bzw. die durch den Verlauf der Sammelschienen definiert wird, wenn sich die Vorrichtung in ihrer Betriebsposition, angeschlossen an das Sammelschienensystem, befindet. Diese bevorzugte Anordnung unterstützt weiter den bereits oben beschriebenen Effekt einer Sicherstellung einer ausreichenden Kühlung des Systems.According to an embodiment of the present invention, the device is designed in such a way that it can be connected to a busbar system. In such a device, both the flat portion of the foot contact and the plane in which the Rogowski coil extends are preferably aligned essentially parallel to a plane in which the busbars run or which is defined by the course of the busbars when the device is in its operating position connected to the busbar system. This preferred arrangement further supports the effect already described above of ensuring adequate cooling of the system.
Gemäß einer anderen Ausführungsform der vorliegenden Erfindung ist die Vorrichtung so ausgebildet, dass sie auf eine Hutschiene montiert werden kann. Bevorzugt sind auch bei einer solchen Vorrichtung sowohl der ebene Teilbereich des Fußkontakts als auch die Ebene, in der sich die Rogowskispule erstreckt, im Wesentlichen parallel zu einer Ebene ausgerichtet, in der die Hutschiene verläuft bzw. die durch den Verlauf der Hutschiene gebildet wird, wenn sich die Vorrichtung in ihrer Betriebsposition, montiert auf der Hutschiene, befindet, was ebenfalls den oben bereits im Zusammenhang mit Sammelschienensystemen beschriebenen Effekte der ausreichenden Kühlung unterstützt.According to another embodiment of the present invention, the device is designed in such a way that it can be mounted on a top-hat rail. With such a device, both the planar portion of the foot contact and the plane in which the Rogowski coil extends are preferably aligned essentially parallel to a plane in which the top-hat rail runs or which is formed by the course of the top-hat rail, if the device is in its operating position, mounted on the DIN rail, which also supports the effects of sufficient cooling already described above in connection with busbar systems.
Gemäß einer weiteren, besonders bevorzugten Ausgestaltung, umfasst eine Vorrichtung gemäß der vorliegenden Erfindung auch eine Passhülse, die so ausgebildet ist, dass nur eine für die Vorrichtung geeignete Sicherung einsetzbar ist. Damit wird sichergestellt, dass Fehlbedienungen, insbesondere das Einsetzen von nicht geeigneten Sicherungen, vermieden werden.According to a further, particularly preferred embodiment, a device according to the present invention also includes a fitting sleeve which is designed in such a way that only a fuse suitable for the device can be used. This ensures that operating errors, in particular the use of unsuitable fuses, are avoided.
Bevorzugt ist eine solche Passhülse so ausgebildet, dass sie einen Aufnahmebereich für einen Teil einer einsetzbaren Sicherung umfasst, wobei der Aufnahmebereich eine Geometrie, insbesondere einen Innendurchmesser aufweist, der an die Geometrie, insbesondere einen Außendurchmesser, der geeigneten Sicherung angepasst ist. Dies stellt insbesondere sicher, dass keine Sicherungen verwendet werden können, die zu einer Überlastung, insbesondere zu einer Überhitzung, des Systems führen könnten.Such a fitting sleeve is preferably designed such that it includes a receiving area for part of an insertable fuse, the receiving area having a geometry, in particular an inner diameter, which is adapted to the geometry, in particular an outer diameter, of the suitable fuse. In particular, this ensures that no fuses can be used that could lead to an overload, in particular to overheating, of the system.
Bevorzugt umfasst eine Vorrichtung gemäß der Erfindung ferner eine Federklammer, die so ausgebildet ist, dass sie den Fußkontakt der Vorrichtung, entweder einer Lasttrennschaltervorrichtung oder einer Schaltersicherungsvorrichtung, und die oben beschriebene Passhülse zumindest teilweise umgreift. Damit werden eine besonders zuverlässige Positionierung und ein besonders zuverlässiger elektrischer Kontakt während des Betriebs sichergestellt.A device according to the invention preferably further comprises a spring clip which is designed in such a way that it at least partially encompasses the base contact of the device, either a switch disconnector device or a switch fuse device, and the fitting sleeve described above. This ensures a particularly reliable positioning and a particularly reliable electrical contact during operation.
Gemäß einer weiteren bevorzugten Ausführungsform ist die Rogowskispule mit einem wärmebeständigen, isolierenden Lack versehen. Dies hat den Vorteil, dass eine galvanische Trennung der Rogowskispule, insbesondere zum Fußkontakt, sichergestellt ist.According to a further preferred embodiment, the Rogowski coil is provided with a heat-resistant, insulating varnish. This has the advantage that a galvanic separation of the Rogowski coil, in particular from the foot contact, is ensured.
Zusätzlich oder alternativ ist gemäß einer bevorzugten Ausführungsform die Vorrichtung so ausgebildet, dass die Abstände zwischen der Rogowskispule und dem Fußkontakt, gegebenenfalls auch zu anderen, stromführenden Teilen, so gewählt, dass selbst ohne den oben beschriebenen wärmebeständigen, isolierenden Lack, eine galvanische Trennung sichergestellt ist.Additionally or alternatively, according to a preferred embodiment, the device is designed in such a way that the distances between the Rogowski coil and the foot contact, possibly also to other current-carrying parts, are selected such that galvanic isolation is ensured even without the heat-resistant, insulating paint described above .
Die galvanische Trennung zwischen der Auswerteelektronik und den strom- oder spannungsführenden Teilen oder Kontakten des Gerätes ist von besonderer Bedeutung. Insbesondere um die elektrische Arbeit zu messen, wird auch eine Messung der Spannung benötigt. Aus diesem Grund ist die Vorrichtung gemäß der Erfindung bei einer bevorzugten Ausführungsform auch so ausgebildet, dass die Spannung kapazitiv oder galvanisch getrennt von den Kontakten der Geräte gemessen wird.The galvanic isolation between the evaluation electronics and the live or live parts or contacts of the device is of particular importance. In particular, in order to measure the electrical work, a measurement of the voltage is also required. For this reason, in a preferred embodiment, the device according to the invention is also designed in such a way that the voltage is measured capacitively or galvanically separately from the contacts of the devices.
Gemäß einer weiteren bevorzugten Ausführungsform ist eine Lasttrennschaltervorrichtung oder eine Schaltersicherungsvorrichtung vorgesehen, die ein Gehäuse und mehrere Eingangsanschlüsse zum Anschluss an eine Stromversorgung und mehrere Ausgangsanschlüsse zum Anschluss an mindestens ein elektrisches Gerät umfasst, wobei die Vorrichtung so ausgebildet ist, dass alle Ausgangsanschlüsse zum Anschluss mindestens eines elektrischen Gerätes an einer Seite des Gehäuses angeordnet sind, wobei sich diese eine Seite im Wesentlichen parallel zu einer Längserstreckung der Sammelschienen oder der Hutschiene und senkrecht zu einer Ebene erstreckt, die durch die Sammelschienen oder die Hutschiene gebildet wird, wenn sich die Vorrichtung in ihrer Betriebsposition, also angeschlossen an das Sammelschienensystem oder montiert auf der Hutschiene, befindet.According to a further preferred embodiment, a load-break switch device or a switch fuse device is provided, which comprises a housing and a plurality of input terminals for connection to a power supply and a plurality of output terminals for connection to at least one electrical device, the device being designed in such a way that all output terminals for connection at least one electrical device are arranged on one side of the housing, this one side extending essentially parallel to a longitudinal extent of the busbars or the top-hat rail and perpendicular to a plane which is formed by the busbars or the top-hat rail when the device is in their operating position, i.e. connected to the busbar system or mounted on the top-hat rail.
Dies hat den Vorteil, dass sämtliche Ausgangsanschlüsse durch den Nutzer sehr einfach zugänglich sind, auch wenn eine Lasttrennschaltervorrichtung oder eine Schaltersicherungsvorrichtung oder mehrere solche Vorrichtungen auf engem Raum vorgesehen sind. Dies erleichtert enorm die Tätigkeit des Nutzers, wenn Änderungen am Gesamtsystem vorgenommen werden müssen, beispielsweise andere elektrische Geräte angeschlossen werden müssen, da insbesondere die Zugänglichkeit deutlich verbessert wird.This has the advantage that all output connections are very easily accessible by the user, even if a load-break switch device or a switch fuse device or several such devices are provided in a confined space. This greatly simplifies the work of the user when changes have to be made to the overall system, for example other electrical devices have to be connected, since accessibility in particular is significantly improved.
