Description

Die Erfindung bezieht sich auf ein Abschalt- bzw. Auslöse­system in einem bei Ueberstrom abschaltenden Installations­einbauschalter bis 25 A von elektrischen Niederspannungs­verteilnetzen, welches System einen thermischen Auslöser mit einem Bimetallstreifen, einen elektromagnetischen Aus­löser aus einem Joch, einem Kern, einer Spule, einem Spu­lenkörper, einem verschiebbaren Anker und einem vom Anker betätigbaren Schlagstift, ein in einer Schaltkammer ange­ordnetes Kontaktsystem mit zwei festen und einem beweg­lichen Kontaktteil mit Kontaktplättchen, und einen manuell betätigbaren, über ein Schaltschloss mit dem Kontaktsystem mechanisch in Eingriff stehenden Schalthebel umfasst. Wei­ter betrifft die Erfindung die Verwendung des Auslöse­systems.The invention relates to a shutdown or tripping system in an overcurrent installation built-in switch up to 25 A of electrical low-voltage distribution networks, which system has a thermal release with a bimetal strip, an electromagnetic release from a yoke, a core, a coil, a coil body, a displaceable armature and a striker pin actuated by the armature, a contact system arranged in a switching chamber with two fixed and a movable contact part with contact plates, and a manually operated switching lever mechanically engaged with the contact system via a switch lock. The invention further relates to the use of the trigger system.

In niedrigen Einstellbereichen bis 1 A sind die Installa­tionseinbauschalter eigenfest, es sind keine Vorsicherungen notwendig. Der im wesentlichen durch thermische und elek­tromagnetische Auslöseelemente gebildete Innenwiderstand begrenzt den Kurzschlussstrom auf einen Wert, der keinen Schaden am Schalter anrichten kann.In low setting ranges up to 1 A, the built-in installation switches are self-locking, no pre-fuses are necessary. The internal resistance, which is essentially formed by thermal and electromagnetic tripping elements, limits the short-circuit current to a value which cannot cause any damage to the switch.

Motorschutzschalter sind in Auslösebereichen bis 6 A eigen­fest. Bei Stromstärken über 6 A muss entweder eine Vorsicherung oder ein Vorschaltblock, auch Is-Begrenzer genannt, zur Uebernahme der Schutzfunktion vorgeschaltet werden. Die Schutzelemente marktgängiger Schalter der hier betrachteten Schaltergruppe üben ihren Schutz bis 25 A Nennstrom aus.Motor protection switches are intrinsically fixed in tripping ranges up to 6 A. In the case of currents above 6 A, either a back-up fuse or a series block, also known as an I s limiter, must be connected upstream to take over the protective function. The protective elements of standard switches in the switch group considered here protect up to 25 A nominal current.

In Fig. 1 werden zwei Prinzipschemen für den Aufbau bekann­ter Motorschutzschalter gezeigt. Bei beiden Schaltertypen ist der Eingangsklemme 10 eine Vorsicherung bzw. ein Strom­ begrenzer 12 bekannter Bauart vorgeschaltet, welche/r für Bereiche oberhalb 6 A ausgelegt sind/ist. Das nach der Ein­gangsklemme 10 in geöffneter Stellung gezeigte Kontaktsy­stem 14 arbeitet mit einfacher Unterbrechung und einem Schlaganker 62 (rechts) oder doppelter Unterbrechung ohne Schlaganker (links). Das Kontaktsystem wird von einem ther­mischen oder von einem elektromagnetischen Ueberstromauslö­ser betätigt. Der elektrische Strom tritt über die Aus­gangsklemme 20 aus dem Schalter aus.In Fig. 1 two basic schemes for the construction of known motor protection switches are shown. In both switch types, the input terminal 10 is a backup fuse or a current upstream limiter 12 of known type, which is / is designed for areas above 6 A. The contact system 14 shown in the open position after the input terminal 10 works with a single interruption and an impact anchor 62 (right) or a double interruption without an impact anchor (left). The contact system is actuated by a thermal or an electromagnetic overcurrent release. The electrical current exits the switch via the output terminal 20.

Aus der FR,A, 2331908 ist ein für hohe Stromstärken geeig­neter Motorschutzschalter bekannt, welcher mittels eines Schaltarms bewegliche Schaltkontakte aufweist und mit Mit­teln zur Schaltarmbetätigung zum Oeffnen oder Schliessen der Schaltkontakte ausgerüstet ist. Diese Mittel umfassen eine elektromagnetische Betätigungsvorrichtung, die in einen Auslösezustand schaltbar ist. Weiter umfassen die Mittel eine den Strom abfühlende Messeinrichtung, die ein der gemessenen Stromstärke proportionales Ausgangssignal erzeugt, und eine auf diese Ausgangssignal ansprechende Steuereinrichtung zur Ausschaltung. Schliesslich umfassen die Mittel eine magnetische Fehlerstrom-Auslösevorrichtung. Dieser Motorschutzschalter benötigt einen Schlitzmotor zur Erzeugung eines stärkeren elektromagnetischen Feldes, das auf den beweglichen Kontakt wirkt.From FR, A, 2331908 a motor protection switch suitable for high currents is known, which has movable switching contacts by means of a switching arm and is equipped with means for actuating the switching arm to open or close the switching contacts. These means comprise an electromagnetic actuation device which can be switched into a tripping state. Furthermore, the means comprise a measuring device which senses the current and which generates an output signal proportional to the measured current strength, and a control device for switching off which responds to this output signal. Finally, the means comprise a magnetic residual current release device. This motor protection switch requires a slot motor to generate a stronger electromagnetic field, which acts on the moving contact.

Der Motorschutzschalter nach der FR,A, 2331908 ist gross, in bezug auf Montage und Material teuer und hat eine grosse Oeffnungsstrecke des beweglichen Kontaktes.The motor protection switch according to FR, A, 2331908 is large, expensive in terms of assembly and material and has a large opening distance for the movable contact.

Die Erfinder haben sich die Aufgabe gestellt, ein Auslöse­system der eingangs genannten Art zu schaffen, welches eigenfest ist und somit weder eine Vorsicherung noch einen Vorschaltblock benötigt, jedoch andrerseits keinen Schlitz­motor mit das elektromagnetische Feld verstärkenden Eisen­teilen benötigt. Das Auslösesystem soll insbesondere für Motorschutz- und Leitungsschutzschalter geeignet und in kompakter Bauweise und gefälligem Design hergestellt sein.The inventors have set themselves the task of creating a triggering system of the type mentioned at the outset, which is inherently fixed and thus does not require a backup fuse or a control block, but on the other hand does not require a slot motor with iron parts which reinforce the electromagnetic field. The tripping system is intended in particular for motor protection and miniature circuit breakers compact design and pleasing design.

Die Aufgabe wird erfingungsgemäss dadurch gelöst, dass im in der Schaltkammer angeordneten Kontaktsystem mit Doppel­unterbrechung ein oberhalb einer bestimmten Stromstärke vom elektromagnetischen Feld ohne verstärkende Hilfsmittel dy­namisch betätigbarer beweglicher Kontakt eingebaut ist.According to the invention, the object is achieved in that a movable contact which can be dynamically actuated above a certain current intensity by the electromagnetic field without amplifying aids is installed in the contact system with double interruption arranged in the switching chamber.

Die Funktion des Vorschaltblocks mit dem dynamischen Kon­takt zur Strombegrenzung im Kontaktsystem ist in der Schaltkammer integriert. Es ist nicht notwendig, einen Schlitzmotor oder dgl. als das elektromagnetische Feld ver­stärkenden Antrieb vorzusehen.The function of the ballast block with the dynamic contact for current limitation in the contact system is integrated in the switching chamber. It is not necessary to provide a slit motor or the like as the electromagnetic field amplifying drive.

Der bewegliche Kontakt weist vorzugsweise eine sehr kleine Masse auf und wird dadurch im Kurzschlussfall äusserst schnell dynamisch geöffnet; ein Abschaltvorgang dauert etwa 1,5 ms. Der Schalter ist dadurch bis wenigstens 16 A, vor­zugsweise bis 25 A, eigenfest. Die Stromunterbrechung er­folgt oberhalb einer vom Schaltertyp abhängigen Stromstär­ke, beispielsweise bei 1250 A.The movable contact preferably has a very small mass and is therefore opened extremely quickly in the event of a short circuit; a shutdown process takes about 1.5 ms. The switch is therefore intrinsically fixed up to at least 16 A, preferably up to 25 A. The current is interrupted above a current that depends on the switch type, for example at 1250 A.

Dem dynamischen Oeffnen des beweglichen Kontaktes folgt der vom Schlaganker beschleunigte Schlagstift. Der Schlaganker als Bestandteil des elektromagnetischen Auslösers gibt nun über einen Mechanismus bekannter Bauart das Schaltschloss frei zur Auslösung; ein Kontaktträger geht in die Aus­schaltposition und verhindert dadurch ein Wiederschliessen der beweglichen Kontakte. Schlaganker und Schlagstift sind in aktivierter Stellung.The dynamic opening of the moving contact is followed by the impact pin accelerated by the impact anchor. The impact anchor as part of the electromagnetic release now releases the switch lock for release via a mechanism of known design; a contact carrier goes into the switch-off position and thereby prevents the moving contacts from closing again. The hammer and hammer are in the activated position.

Der feste Kontaktteil besteht bevorzugt aus zwei in bezug auf die Verschiebungsachse des Ankers plansymmetrisch aus­gebildeten Bügeln mit je einem Kontaktplättchen. In diesem Fall besteht der bewegliche Kontaktteil aus einer Schalt­brücke mit beidseits in bezug auf die vorstehend erwähnte Achse symmetrisch angeordneten Kontaktplättchen.The fixed contact part preferably consists of two brackets which are plane-symmetrical with respect to the displacement axis of the armature, each with a contact plate. In this case, the movable contact part consists of a switching bridge with contact plates arranged symmetrically on both sides with respect to the aforementioned axis.

Der untere Schenkel der festen Kontaktteile ist als Leit­blech für den Lichtbogen zu einem der beidseitig angeordne­ten Löschpakete ausgebildet.The lower leg of the fixed contact parts is designed as a guide plate for the arc to one of the quenching packages arranged on both sides.

Der bewegliche Kontaktteil liegt in geöffneter Stellung be­vorzugt am unteren Lichtbogenleitblech zu den beidseitig angeordneten Löschpaketen an.In the open position, the movable contact part is preferably in contact with the lower arc guide plate for the quenching packages arranged on both sides.

Der koaxial zum Anker bzw. Kern verlaufende Schlagstift wird einends in einer Oeffnung des Jochs und andernends im Kontaktträger geführt. Der Schlagstift ist elektrisch iso­lierend, weist eine kleine Trägheit auf und gleitet leicht und ungeschmiert.The striking pin, which runs coaxially to the armature or core, is guided at one end in an opening in the yoke and at the other end in the contact carrier. The striker is electrically insulating, has a small inertia and slides easily and without lubrication.

Das erfindungsgemässe Auslösesystem wird vorzugsweise in einem Motorschutzschalter oder Leitungsschutzschalter ver­wendet, insbesondere in einem dreipoligen Motorschutzschal­ter mit gemeinsamem Schaltschloss und Schalthebel.The tripping system according to the invention is preferably used in a motor protection switch or circuit breaker, in particular in a three-pole motor protection switch with a common switch lock and switch lever.

Die Erfindung wird anhand von in der Zeichnung dargestell­ten Ausführungsbeispielen näher erläutert. Es zeigen sche­matisch:

  • Fig. 2 das Prinzip des Schalteraufbaus,
  • Fig. 3 einen vertikalen Längsschnitt durch eine Schalt­kammer mit dem Auslösesystem in Ausschaltlage, und
  • Fig. 4 das in Fig. 3 gezeigte Auslösesystem in Ein­schaltlage.
The invention is explained in more detail with reference to exemplary embodiments shown in the drawing. They show schematically:
  • 2 shows the principle of the switch structure,
  • Fig. 3 is a vertical longitudinal section through a switching chamber with the release system in the off position, and
  • Fig. 4 shows the trigger system shown in Fig. 3 in the on position.

Im Prinzipschema für den Schalteraufbau gemäss Fig. 2 ist leicht ersichtlich, dass die gemäss dem Stand der Technik notwendige Vorschaltung 12, in Fig. 1 dargestellt, fehlt. Der Strom wird direkt zur Eingangsklemme 10 geleitet. Ueber das Kontaktsystem 14 mit doppelter Unterbrechung und Schlaganker 62, hier nur übersichtlichkeitshalber in Aus­schaltlage gezeigt, fliesst er weiter zum thermischen Ueberstromauslöser 16, einem Bimetallstreifen. Durch den elektromagnetischen Ueberstromauslöser 18 wird der elektri­sche Strom zur Ausgangsklemme 20 und von dort zu einem nicht gezeigten Verbraucher geführt.In the basic diagram for the switch structure according to FIG. 2, it is readily apparent that the ballast 12 required according to the prior art, shown in FIG. 1, is missing. The current is fed directly to input terminal 10. Via the contact system 14 with a double break and Impact anchor 62, shown here in the switch-off position for the sake of clarity, it flows further to the thermal overcurrent release 16, a bimetallic strip. Through the electromagnetic overcurrent release 18, the electrical current is led to the output terminal 20 and from there to a consumer, not shown.

Im in Fig. 3 und 4 dargestellten Auslösesystem sind das vom Schalthebel 26 betätigte Schaltschloss 76 und die die Kraft vom thermischen und elektromagnetischen Ueberstromauslöser auf das Schaltschloss übertragenden Teile nur angedeutet oder weggelassen. Ebenso ist das Gehäuse 24 nur soweit ge­zeichnet, als es zur Darstellung des Ueberstromauslösesy­stems notwendig ist. Nur angedeutete oder weggelassene Tei­le sind von üblicher Bauart und für die Erfindung nicht charakteristisch.In the release system shown in FIGS. 3 and 4, the switch lock 76 actuated by the switching lever 26 and the parts transmitting the force from the thermal and electromagnetic overcurrent release to the switch lock are only indicated or omitted. Likewise, the housing 24 is only drawn as far as is necessary to represent the overcurrent release system. Only indicated or omitted parts are of conventional design and not characteristic of the invention.

In der Eingangsklemme 10 wird ein nicht dargestellter elek­trischer Leiter mit einer Schraube 28 auf eine Verbindungs­schiene 30 gedrückt, welche entlang des Gehäusebodens ins Innere der Schaltkammer 32 führt. Mit einer weiteren Schraube 34 wird die Verbindungsschiene 30 mit dem bügelar­tig ausgebildeten festen Kontakt 36 elektrisch leitend verbunden. Der untere Teil des festen Kontakts 36 ist eben­falls im Gehäuseboden fixiert und ist, sich nach aussen in geschwungener Linie öffnend, als oberes Leitblech für den Lichtbogen ausgebildet.In the input terminal 10, an electrical conductor (not shown) is pressed with a screw 28 onto a connecting rail 30, which leads along the housing base into the interior of the switching chamber 32. With a further screw 34, the connecting rail 30 is connected in an electrically conductive manner to the fixed contact 36 which is designed in the form of a bracket. The lower part of the fixed contact 36 is also fixed in the housing base and, opening outwards in a curved line, is designed as an upper guide plate for the arc.

Jeder der beiden symmetrisch ausgebildeten und angeordneten festen Kontakte 36 hat auf der untern Seite ein Kontakt­plättchen 40.Each of the two symmetrically designed and arranged fixed contacts 36 has a contact plate 40 on the lower side.

Der bewegliche Kontaktteil 42, als Kontaktbrücke ausgebil­det, hat ebenfalls zwei Kontaktplättchen 44, welche in der in Fig. 4 dargestellten geschlossenen Stellung auf den Kon­taktplättchen 40 des festen Kontaktteils 36 liegen. Damit wird ein Doppelunterbrechungssystem gebildet, dessen beweg­ licher Kontakt eine sehr kleine Masse aufweist und somit im Kurzschlussfall als erster Schritt dynamisch geöffnet wird. Dadurch wird eine sehr wirksame Strom- und Energiebegren­zung erreicht, mit einem geringen resultierenden I²dt-Wert. Mit den beiden Löschblechpaketen 52, die eine bestimmte An­zahl Löschbleche 54 enthalten, wird eine hohe Lichtbogen­spannung und Lichtbogenunterteilung erreicht, was für den Abschaltvorgang Vorraussetzung ist.The movable contact part 42, designed as a contact bridge, also has two contact plates 44 which, in the closed position shown in FIG. 4, lie on the contact plates 40 of the fixed contact part 36. This creates a double break system, the moving contact has a very small mass and is therefore opened dynamically as a first step in the event of a short circuit. This results in a very effective current and energy limitation with a low resulting I²dt value. With the two quenching plate packages 52, which contain a certain number of quenching plates 54, a high arc voltage and arc division is achieved, which is a prerequisite for the switch-off process.

Im Boden 46 des Gehäuses ist ein für den Lichtbogen ge­schweift ausgebildetes unteres Leitblech 50 eingelegt, das sich wie das obere Leitblech 38 nach aussen öffnet. Der be­wegliche Kontaktteil 42 ist in der Ausschaltlage an das untere Leitblech 50 angeformt.In the bottom 46 of the housing there is inserted a lower guide plate 50 which is curved for the arc and which, like the upper guide plate 38, opens outwards. The movable contact part 42 is molded onto the lower guide plate 50 in the switched-off position.

Zweckmässig bestehen die festen Kontaktteile 36 aus plat­tiertem Kupfer-Stahlband zur Erreichung eines magnetischen Feldes zur Lichtbogenablenkung, die beweglichen Kontakttei­le 42 aus Kupfer, das untere Leitblech 50 und die Lösch­bleche 54 des Löschpakets 52 aus Stahl, die Kontaktplätt­chen 40, 44 aus einer Silberlegierung.The fixed contact parts 36 are expediently made of plated copper-steel strip to achieve a magnetic field for arc deflection, the movable contact parts 42 are made of copper, the lower guide plate 50 and the quenching plates 54 of the quenching package 52 are made of steel, the contact plates 40, 44 are made of a silver alloy.

Der bei der Ausgangsklemme 20 liegende feste Kontaktteil 36 ist mittels einer Schraube mit dem Joch 72 verbunden. An einem am Joch 72 angeformten Biegelappen ist durch Punkt­schweissen ein Bimetall 16 für die thermische Auslösung be­festigt. Dessen obere Zunge 17 greift in ein Auslösesystem - im vorliegenden Fall mit einem verschiebbaren Schlitten 56 - ein, welches bei Ueberstrom mit nicht dargestellten Mitteln das Schaltschloss 76 auslöst.The fixed contact part 36 located at the output terminal 20 is connected to the yoke 72 by means of a screw. A bimetal 16 for thermal triggering is attached to a bending tab formed on the yoke 72 by spot welding. Its upper tongue 17 engages in a release system - in the present case with a displaceable slide 56 - which triggers the switch lock 76 in the event of overcurrent using means not shown.

Im Bereich des freien Endes des Bimetallstreifens 16 ist eine Heizwicklung 58 angeschweisst, welche der zusätzlichen Erwärmung des Bimetallstreifens 16 dient.In the area of the free end of the bimetal strip 16, a heating winding 58 is welded on, which serves for the additional heating of the bimetal strip 16.

Die Heizwicklung 58 ist mit der Spule 60 des elektromagne­tischen Auslösers verbunden, welcher in der Längsmitte des Motorschutzschalters eingebaut ist. Der entlang der Längs­achse A des elektromagnetischen Ueberstromauslösers ver­schiebare Anker 62 ist gemäss Fig. 3 in den Spulenkörper 64 eingeführt.The heating winding 58 is connected to the coil 60 of the electromagnetic release, which in the longitudinal center of the Motor protection switch is installed. The armature 62, which is displaceable along the longitudinal axis A of the electromagnetic overcurrent release, is inserted into the coil body 64 according to FIG. 3.

Der Schlagstift 66 liegt im nicht aktiven Zustand, in Ein­schaltlage des Kontaktsystems, lose zwischen dem Anker 62 und dem beweglichen Kontaktteil 42. Dieser bewegliche Kon­takt liegt auf einem Kontaktträger 70, der via zwei ange­formte Stössel 78 und einen Winkelhebel 77 vom Schalt­schloss 76 in die Ein- oder Ausschaltlage gebracht wird, unter Mithilfe einer Spiralfeder 68.The striker pin 66 is in the non-active state, in the switched-on position of the contact system, loosely between the armature 62 and the movable contact part 42. This movable contact lies on a contact carrier 70, which is connected via two molded plungers 78 and an angle lever 77 from the key switch 76 to the on - or switched off position, with the help of a spiral spring 68.

Der bevorzugt aus einem Kunststoff, insbesondere einem Thermoplast, bestehende Schlagstift 66 ist entlang der Längsachse A verschiebbar; er dringt durch den hülsenförmig ausgebildeten Kern 67 und wird im Gehäuseboden 74 einer­seits sowie in einer Oeffnung im Kontaktträger 70 für den beweglichen Kontaktteil 42 andrerseits geführt, wobei der aus Kunststoff bestehende Gehäuseboden 74 und Kontaktträger 70 Gleitlager bilden.The striker pin 66, which is preferably made of a plastic, in particular a thermoplastic, is displaceable along the longitudinal axis A; it penetrates through the sleeve-shaped core 67 and is guided in the housing base 74 on the one hand and in an opening in the contact carrier 70 for the movable contact part 42 on the other hand, the plastic housing base 74 and contact carrier 70 forming slide bearings.

In der in Fig. 4 dargestellten Einschaltlage ist das Schaltschloss durch Betätigen des Schalthebels 26 gespannt worden. Der freigegebene Schlaganker 62 wird in Axialrich­tung A mittels einer Feder 75, welche das Anziehen des An­kers beim normalen Nennstrom verhindert, in Ruhelage gehal­ten. Die Druckfeder 68 hat den beweglichen Kontaktteil 42 mit dem Kontaktträger 70 verschoben, die Kontaktplättchen 40, 44 liegen elektrisch leitend aufeinander.In the switch-on position shown in FIG. 4, the switching lock has been tensioned by actuating the switching lever 26. The released impact armature 62 is held in the rest position in the axial direction A by means of a spring 75, which prevents the armature from tightening at the normal rated current. The compression spring 68 has moved the movable contact part 42 with the contact carrier 70, the contact plates 40, 44 lie on one another in an electrically conductive manner.

In einem dreiphasigen Motorschutzschalter sind die in den Fig. 3 und 4 dargestellten Schaltkammern 32 mit Kontaktsy­stem sowie das thermische und elektromagnetische Auslöse­element mit den Anschlussklemmen dreimal parallel neben­einander angeordnet. Die drei beweglichen Kontakte 42 sind in einem gemeinsamen Kontaktträger 70 gelagert und werden von diesem betätigt. Der Antrieb des Kontaktträgers 70 er­folgt vom Schaltschloss 76 aus über den Winkelhebel 77.In a three-phase motor protection switch, the switching chambers 32 with contact system shown in FIGS. 3 and 4 and the thermal and electromagnetic trigger element with the connection terminals are arranged three times in parallel next to one another. The three movable contacts 42 are stored in a common contact carrier 70 and are operated by this. The contact carrier 70 is driven from the key switch 76 via the angle lever 77.
