Abstract

The invention relates to a resistor device comprising stacked annular resistor elements with the same axis, in each case having two contact devices bearing diametrically on different end faces of the individual resistor elements. In order to produce a resistor device that is comparatively simple to manufacture, with a high resistance value and a relatively short installed height, each contact device consists of a conductive bar (3), the longitudinal axis (3a) of which extends parallel to the axis (2a) of the resistor elements (2). In the region of the end faces of adjacent resistor elements (2) which is free of the conductive bar (3) there is at least one insulating spacer (4). The resistor device can be used with advantage in metal-encapsulated high-voltage circuit breaker installations (figure 1). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Widerstandseinrichtung mit in derselben Achse zu einem Stapel übereinander geschichteten, ringförmigen Widerstandselementen mit jeweils zwei diametral an verschiedenen StirnflächenThe invention relates to a resistance device with ring-shaped resistance elements stacked one above the other in the same axis to form a stack, each with two diametrically opposed end faces

der einzelnen Widerstandselemente anliegenden Kontakteinrichtungen:

  • Bei einer bekannten, einen Überspannungsableiter bildenden Widerstandseinrichtung dieser Art (DE-PS 11 89 636) ist jedes Widerstandselement durch aufmetallisierte Kontaktbeläge in zwei etwa halbmondförmige Teilwiderstände unterteilt. Diese Teilwiderstände sind durch zwei parallel liegende und durch die Mittenbohrung geführte Schaltbänder in Serie geschaltet. Jeweils benachbarte ringförmige Widerstandselemente der bekannten Widerstandseinrichtung sind durch eine Kontakteinrichtung galvanisch miteinander verbunden, die zwei Anschlußfahnen enthält; die beiden Anschlußfahnen liegen auf diametral einander zugewandten Stirnflächen der benachbarten Widerstandselemente an und ermöglichen dadurch einen Stromdurchfluß vom einen Teilwiderstand des einen Widerstandselementes zum anderen Teilwiderstand des benachbarten Widerstandselementes. Der Stromdurchfluß durch jeden einzelnen Teilwiderstand der ringförmigen Widerstandselemente erfolgt bei der bekannten Widerstandseinrichtung in einer Richtung parallel zur Achse der Widerstandselemente.
of the individual contact elements attached to the resistance elements:
  • In a known resistance device of this type, which forms a surge arrester (DE-PS 11 89 636), each resistance element is subdivided into two approximately half-moon-shaped partial resistors by metallized contact coatings. These partial resistors are connected in series by two switching tapes in parallel and routed through the center hole. In each case adjacent ring-shaped resistance elements of the known resistance device are galvanically connected to one another by a contact device which contains two connecting lugs; the two connecting lugs rest on diametrically facing end faces of the adjacent resistance elements and thereby enable a current to flow from one partial resistance of one resistance element to the other partial resistance of the adjacent resistance element. The current flow through each individual partial resistance of the annular resistance elements takes place in the known resistance device in a direction parallel to the axis of the resistance elements.

Der Erfindung liegt die Aufgabe zugrunde, eine Wider- .standseinrichtung zu schaffen, die vergleichsweise einfach herstellbar ist und sich durch einen hohen Widerstandswert bei verhältnismäßig geringer Bauhöhe auszeichnet.The object of the invention is to create a resistance device which is comparatively simple to manufacture and which is distinguished by a high resistance value with a relatively low overall height.

Zur Lösung dieser Aufgabe besteht bei einer Widerstandseinrichtung der eingangs angegebenen Art erfindungsgemäß jede Kontakteinrichtung aus einem leitenden Stab, dessen Längsachse sich parallel zur Achse der Widerstandselemente erstreckt; in dem vom Stab freien Bereich der Stirnflächen benachbarter Widerstandselemente befindet sich mindestens ein isolierendes Abstandsteil.To achieve this object, in a resistance device of the type specified at the outset, according to the invention, each contact device consists of a conductive rod, the longitudinal axis of which extends parallel to the axis of the resistance elements; At least one insulating spacer is located in the area of the end faces of adjacent resistance elements that is free of the rod.

Ein wesentlicher Vorteil der erfindungsgemäßen Widerstandseinrichtung besteht darin, daß ihre Kontakteinrichtungen verhältnismäßig einfach ausgebildet sind, weil sie jeweils nur aus einem leitenden Stab bestehen. Dies ist dadurch ermöglicht, daß bei der erfindungsgemäßen Widerstandseinrichtung der Stromverlauf in dem einzelnen ringförmigen Widerstandselement nicht in einer Richtung parallel zur Achse der Widerstandselemente erfolgt, sondern ringförmig in jedem Widerstandselement. Dies bringt auch den Vorteil mit sich, daß in der erfindungsgemäßen Widerstandseinrichtung für den Strom eine im Vergleich zu den Abmessungen der Widerstandseinrichtung lange Strombahn mit einem großen ohmschen Widerstand gebildet wird. Zur Erzielung einer Widerstandseinrichtung mit einem verhältnismäßig großen ohmschen Widerstandswert werden daher nur relativ wenige ringförmige Widerstandselemente benötigt; infolgedessen ist auch die Bauhöhe der erfindungsgemäßen Widerstandseinrichtung verhältnismäßig gering, so daß sie überall dort besonders vorteilhaft eingesetzt werden kann, wo beengte Raumverhältnisse vorliegen. Dies gilt beispielsweise für die Anwendungsfälle der erfindungsgemäßen Widerstandseinrichtung, in denen sie innerhalb der Kapsel einer vollisolierten, metallgekapselten Hochspannungsschaltanlage eingesetzt werden soll.A major advantage of the resistance device according to the invention is that its contact devices are relatively simple because they each consist of only one conductive rod. This is made possible by the fact that, in the resistance device according to the invention, the current profile in the individual annular resistance element does not take place in a direction parallel to the axis of the resistance elements, but in a ring shape in each resistance element. This also has the advantage that a current path with a large ohmic resistance is formed for the current in the resistance device according to the invention in comparison with the dimensions of the resistance device. To achieve a resistance device with a relatively large ohmic resistance value, therefore, only relatively few ring-shaped resistance elements are required; as a result, the overall height of the resistance device according to the invention is relatively low, so that it can be used particularly advantageously wherever confined space relationships exist. This applies, for example, to the applications of the resistance device according to the invention, in which it is to be used within the capsule of a fully insulated, metal-encapsulated high-voltage switchgear.

Es ist zwar bereits eine Widerstandseinrichtung bekannt (DD-PS 40 771), bei der ringförmige Widerstandselemente von dem Strom ringförmig durchflossen werden, jedoch stellen die Widerstandselemente dieser bekannten Widerstandseinrichtung nur Kreissegmente dar, die im Bereich der öffnungsstelle mit Kontaktierungen versehen sind, um seitlich den Strom in die Widerstandselemente einleiten zu können. Die Verbindung der einzelnen Widerstandselemente untereinander ist daher bei der bekannten Widerstandseinrichtung verhältnismäßig aufwendig.Although a resistance device is already known (DD-PS 40 771), in which annular resistance elements are flowed through in a ring shape by the current, however, the resistance elements of this known resistance device only represent circular segments which are provided with contacts in the area of the opening point, around the side To be able to introduce current into the resistance elements. The connection of the individual resistance elements to one another is therefore relatively complex in the known resistance device.

Bei der erfindungsgemäßen Widerstandseinrichtung kann das isolierende Abstandsteil in unterschiedlicher Weise ausgebildet sein. Beispielsweise kann es aus einem offenen Ringteil bestehen, das dem leitenden Stab diametral gegenüber angeordnet ist. Als besonders vorteilhaft wird es jedoch erachtet, wenn das isolierende Abstandsteil aus einem Isolierstab besteht, der dem leitenden Stab diametral gegenüber angeordnet ist. Diese Ausführungsform läßt sich nämlich besonders einfach herstellen.In the resistance device according to the invention, the insulating spacer can be designed in different ways. For example, it can consist of an open ring part which is arranged diametrically opposite the conductive rod. However, it is considered particularly advantageous if the insulating spacer consists of an insulating rod which is arranged diametrically opposite the conductive rod. This embodiment is particularly easy to manufacture.

Der konstruktive Zusammenhalt der Widerstandselemente, der leitenden Stäbe und der isolierenden Abstandsteile kann ebenfalls unterschiedlich vorgenommen werden. Beispielsweise ist ein Verspannen dieser Teile miteinander über Isolierplatten und isolierende Spannbolzen möglich. Eine vor allem fertigungstechnisch günstige Ausführungsform wird jedoch darin gesehen, daß die Widerstandselemente, die leitenden Stäbe und die isolierenden Abstandsteile in einem Gießharzkörper eingebettet sind. In diesem Falle wird also allein durch einen Gießharzverguß der konstruktive Zusammenhalt der genannten Teile der Widerstandseinrichtung bewirkt.The structural cohesion of the resistance elements, the conductive rods and the insulating spacers can also be done differently. For example, these parts can be clamped together using insulating plates and insulating clamping bolts. A particularly favorable embodiment in terms of production technology is seen in the fact that the contra stand elements, the conductive rods and the insulating spacers are embedded in a cast resin body. In this case, the structural cohesion of the aforementioned parts of the resistance device is brought about solely by casting resin.

Um mit möglichst wenig Gießharz auszukommen und um eine im Gewicht möglichst günstige Widerstandseinrichtung zu gewinnen, ist der Gießharzkörper vorteilhafterweise ein Hohlzylinder. Eine solche Ausbildung ermöglicht es, innerhalb der Widerstandseinrichtung zusätzliche Schaltungselemente unterzubringen. Soll die erfindungsgemäße Widerstandseinrichtung im Rahmen einer Hochspannungsanlage Verwendung finden, dann befindet sich innerhalb der Widerstandseinrichtung vorteilhafterweise eine Kondensatorsäule; durch diese Säule läßt sich eine kapazitive Steuerung erreichen.In order to get by with as little casting resin as possible and to obtain a resistance device that is as cheap as possible in weight, the casting resin body is advantageously a hollow cylinder. Such a design makes it possible to accommodate additional circuit elements within the resistance device. If the resistance device according to the invention is to be used in the context of a high-voltage system, then a capacitor column is advantageously located within the resistance device; capacitive control can be achieved through this column.

Die Ausführung der erfindungsgemäßen Widerstandseinrichtung als Gießharzkörper schafft ferner die vorteilhafte Möglichkeit in diesem Gießharzkörper äußere Kontaktringe einzubetten, über die die Widerstandseinrichtung anschließbar ist.The design of the resistance device according to the invention as a cast resin body also creates the advantageous possibility of embedding external contact rings in this cast resin body, via which the resistance device can be connected.

  • Fig. 2 shows a cross section through the same embodiment.

Die dargestellte Widerstandseinrichtung 1 enthält ringförmige Widerstandselemente 2, die übereinander geschichtet sind, wobei ein Stapel mit einer mit der Achse der Widerstandselemente 2 zusammenfallenden Achse 2a gebildet ist. Zwischen jeweils benachbarten Widerstandselementen 2 ist ein leitender Stab 3 angeordnet, dem ein Isolierstab 4 diametral gegenüberliegt (siehe auch Fig. 2). Die Längsachse 3a der leitenden Stäbe 3 erstreckt -sich parallel zur Achse 2a der Widerstandselemente.The resistance device 1 shown contains ring-shaped resistance elements 2, which are layered one above the other, a stack with one having the axis of Resistance elements 2 coincident axis 2a is formed. Between each of the adjacent resistance elements 2, a conductive rod 3 is arranged, which an insulating rod 4 is diametrically opposite (see also Fig. 2). The longitudinal axis 3a of the conductive bars 3 extends parallel to the axis 2a of the resistance elements.

Am in der Fig. 1 oberen Ende der Widerstandseinrichtung 1 befindet sich ein äußerer Kontaktring 5, der auf dem benachbarten leitenden Stab 3 und dem benachbarten Isolierstab 4 aufliegt. Der Kontaktring 5 ist mit Bohrungen 6 versehen, damit an ihm mittels Schrauben 7 ein metallenes Verbindungsstück 8 befestigt werden kann. Dieses Verbindungsstück 8 ist mit einem Sackloch 9 versehen, in das ein nicht dargestelltes Kontaktstück zum Anschluß der Widerstandseinrichtung 1 eingeführt werden kann.At the upper end of the resistance device 1 in FIG. 1 there is an outer contact ring 5 which rests on the adjacent conductive rod 3 and the adjacent insulating rod 4. The contact ring 5 is provided with holes 6 so that a metal connecting piece 8 can be fastened to it by means of screws 7. This connector 8 is provided with a blind hole 9 into which a contact piece, not shown, for connecting the resistance device 1 can be inserted.

In ähnlicher Weise ist die Widerstandseinrichtung 1 an ihrem in der Fig. 1 unteren Ende ausgebildet. Dort ist ein weiterer äußerer Kontaktring 10 mit Gewindebohrungen 11 vorhanden; mittels Schrauben 12 wird mit dem weiteren Kontaktring 10 ein weiteres Verbindungsstück 13 verschraubt, das an seinem äußeren Umfang eine Schirmelektrode 14 trägt. Das weitere Verbindungsstück 10 weist ebenfalls eine Mittenausnehmung 15 auf, um einen nicht dargestellten Kontaktstift zum Anschluß dieses Endes der Widerstandseinrichtung 1 einführen zu können.The resistance device 1 is formed in a similar manner at its lower end in FIG. 1. There is another outer contact ring 10 with threaded holes 11; by means of screws 12, a further connecting piece 13 is screwed to the further contact ring 10, which carries a shield electrode 14 on its outer circumference. The further connecting piece 10 also has a central recess 15 in order to be able to insert a contact pin (not shown) for connecting this end of the resistance device 1.

Die Widerstandselemente 2, die leitende Stäbe 3 und die Isolierstäbe 4 sind zusammen mit den Kontaktringen 5 und 10 in einem Gießharzkörper 16 eingebettet, der einen Hohlzylinder darstellt. Der Hohlzylinder kann als gerader Zylinder ausgebildet sein; es ist aber auch möglich, den Hohlzylinder nach oben hin konisch zulaufen zu lassen.The resistance elements 2, the conductive rods 3 and the insulating rods 4 are embedded together with the contact rings 5 and 10 in a cast resin body 16, which is a hollow cylinder. The hollow cylinder can be designed as a straight cylinder; but it is also possible to have the hollow cylinder taper upwards.

Die Kondensatorsäule 17 befindet sich in Kontakt mit den Kontaktringen 5 und 10 und ist somit auch an die Spannung angeschlossen, an der die Widerstandseinrichtung 1 liegt. Durch die Kondensatorsäule 17 wird eine kapazitive Steuerung und eine Entlastung der Widerstandseinrichtung 1 bei Stoßspannungen erreicht, wenn der Widerstandseinrichtung 1 eine kleinere Kapazität, z. B. in Form eines induktiven Spannungswandlers, nachgeordnet ist.In the exemplary embodiment shown, inside the cast resin body 16 there is a capacitor column 17 composed of a plurality of capacitors 18 which are stacked one above the other and thus form a series connection. The capacitor column 17 is in contact with the contact rings 5 and 10 and is thus also connected to the voltage at which the resistance device 1 is connected. Through the capacitor column 17, a capacitive control and a relief of the resistance device 1 at surge voltages is achieved when the resistance device 1 has a smaller capacitance, for. B. in the form of an inductive voltage converter.
