Description

Die Erfindung betrifft ein elektrisches Schaltgerät, insbesondere einen Hauptleitungsschutzschalter gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electrical switching device, in particular a main circuit breaker according to the preamble of claim 1.

Ein solcher Schalter ist aus der DE 28 54 711 bekannt geworden. Er besitzt eine erste Kontaktstelle, zu der ein Parallelstrompfad geschaltet ist, in dem ein Strombegrenzungswiderstand eingesetzt ist.Such a switch has become known from DE 28 54 711. It has a first contact point, to which a parallel current path is connected, in which a current limiting resistor is inserted.

Eine solche Anordnung ist auch in dem Hauptleitungsschutzschalter S 700 der Firma ABB Stotz-Kontakt GmbH Heidelberg verwirklicht. Der Widerstand dort ist als Widerstandsdraht zum Beispiel aus CrAl255, Cu oder aus anderen Legierungen hergestellt, wobei der Draht zu einer Spule gewickelt ist, die aufgrund ihrer Bauform und des geforderten Widerstandswertes einen relativ großen Bauraum beansprucht. Darüber hinaus erzeugt ein solcher spulenförmiger Widerstand ein großes Magnetfeld, so daß die Spule aufwendig antiparallel gewickelt werden muß. Beim Einsatz von blanken Drähten muß die Spule auf einen hochtemperaturbeständigen Trägerkörper gewickelt werden, um zu verhindern, daß sich die Windungen bei Strombeaufschlagung anziehen und somit einen Windungsschluß verursachen. Wenn der Widerstandsdraht isoliert ist, dann kommen als Isolierelemente teure und schlecht handhabbare Materialien, wie z. B. Glasseide zum Einsatz.Such an arrangement is also realized in the main circuit breaker S 700 from ABB Stotz-contact GmbH Heidelberg. The resistor there is made as a resistance wire, for example made of CrAl255, Cu or other alloys, wherein the wire is wound into a coil, which claims a relatively large amount of space due to their design and the required resistance value. In addition, such a coil-shaped resistor generates a large magnetic field, so that the coil must be wound consuming anti-parallel. When using bare wires, the coil must be wound on a high temperature resistant support body to prevent the windings attract when energized and thus cause a Windungsschluß. If the resistance wire is insulated, then come as insulating expensive and poorly manageable materials such. B. glass silk used.

Aufgabe der Erfindung ist es, einen Schalter der Eingangs genannten Art zu schaffen, bei dem die Nachteile der bekannten Anordnung vermieden sind.The object of the invention is to provide a switch of the type mentioned, in which the disadvantages of the known arrangement are avoided.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.

Erfindungsgemäß also befindet sich in dem parallel zur ersten Kontaktstelle liegenden Parallelstrompfad ein Widerstandskörper, der aus dotierter Keramik besteht, deren Temperaturkoefizient gleich oder negativ ist.Thus, according to the invention, a resistor body which consists of doped ceramic whose temperature coefficient is the same or negative is located in the parallel current path parallel to the first contact point.

Dadurch wird die Verwendung eines Widerstandsdrahtes in Form einer Spule mit all den Nachteilen vermieden und der Widerstandskörper benötigt auch geringeren Platz innerhalb des Schaltgerätes.As a result, the use of a resistance wire in the form of a coil with all the disadvantages is avoided and the resistor body also requires less space within the switching device.

Das Widerstandsmaterial zur Bildung des Widerstandskörpers ist im Handel erhältlich. Es besteht aus einer Mischung von Ton, Aluminium und Kohlenstoff, das nach Zusammenpressen auf seine Endform einem Sinterverfahren unterworfen ist.The resistor material for forming the resistor body is commercially available. It consists of a mixture of clay, aluminum and carbon, which is subjected to a sintering process after being pressed to its final shape.

Wenn der Leitungsschutzschalter mit einem aus zwei Schalenhälften zusammengesetzten Gehäuse versehen ist, besitzen die Schalenhälften senkrecht zur Innenfläche der Breitseite verlaufende Leisten, die nach Zusammenbau der Schalenhälften einen Raum begrenzen, in dem der Widerstandskörper aufgenommen und gehaltert ist.If the circuit breaker is provided with a housing composed of two shell halves, the shell halves have perpendicular to the inner surface of the broad side extending strips which define after assembly of the shell halves a space in which the resistance body is received and supported.

Zur Kontaktierung wird in bevorzugter Weise eine Federkontaktierung vorgesehen.For contacting a spring contacting is provided in a preferred manner.

Weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments and improvements of the invention can be found in the further subclaims.

Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen und weitere Vorteile näher erläutert und beschrieben werden.Reference to the drawing, in which an embodiment of the invention is shown, the invention and further advantageous refinements and improvements and other advantages are explained and described in detail.

Ein Leitungsschutzschalter besitzt ein Gehäuse 10, das entweder aus einem schalenförmigen Gehäuseunterteil und einem Deckel oder aus zwei etwa gleichen Schalenhälften gebildet sein kann. Innerhalb dieses Gehäuses 10 befindet sich eine erste Kontaktstelle 11 mit einem feststehenden Kontaktstück 12 und einem beweglichen Kontaktstück 13; das bewegliche Kontaktstück 13, das an einem schwenkbaren Kontakthebel 14 angeordnet ist, wird von einem Elektromagneten bei Auftreten eines Kurzschlußstromes verschwenkt, so daß die Kontaktstelle 11 geöffnet wird. Dieser Kontaktstelle 11 ist ein Parallelstrompfad 15 zugeordnet, in dem sich ein Widerstandskörper 16 befindet; wenn die Kontaktstelle 11 geöffnet wird, entsteht dort ein Lichtbogen, der in ein Lichtbogenlöschblechpaket 17 wandert; darüber hinaus wird der Strom in den Nebenstrompfad 15 kommutiert und durch den elektrischen Widerstand des Widerstandskörpers 16 begrenzt.A circuit breaker has a housing 10 which may be formed either of a cup-shaped housing lower part and a lid or two approximately the same shell halves. Within this housing 10 is a first contact point 11 with a fixed contact piece 12 and a movable contact piece 13; the movable contact piece 13, which is arranged on a pivotable contact lever 14, is pivoted by an electromagnet when a short-circuit current occurs, so that the contact point 11 is opened. This contact point 11 is associated with a parallel current path 15, in which a resistance body 16 is located; when the contact point 11 is opened, there arises an arc which migrates into an arc splitter stack 17; In addition, the current is commutated in the secondary current path 15 and limited by the electrical resistance of the resistor body 16.

Ein elektrisches Ersatzschaltbild dieses Schaltgerätes ist in Fig. 5 dargestellt. In einem Hauptstrompfad 18 befindet sich die erste Kontaktstelle 11 so wie ein zweite Kontaktstelle 19. Parallel zu der ersten Kontaktstelle 11 ist der Parallelstrompfad 15 geschaltet, in dem der Widerstandskörper 16 angeordnet ist. Elektrisch in Reihe zu dem Widerstandskörper 16 befindet sich ein in der Fig. 1 nicht näher dargestelltes Selektivthermobimetall 20, welches auf ein Schaltschloß 21 wirkt, das in der Fig. 1 gezeigt ist und an dem ein Schaltknebel 22 angeordnet bzw. angelenkt ist. Im Hauptstrompfad 18 befindet sich ein weiteres Thermobimetall 36, das in der Fig. 1 ebenfalls nicht dargestellt ist; dieses Thermobimetall wirkt ebenfalls auf das Schaltschloß 21, wobei das Schaltschloß 21 über die Wirklinie 23 mit der Kontaktstelle 19 verbunden ist.An electrical equivalent circuit diagram of this switching device is shown in Fig. 5. In a main current path 18, the first contact point 11 is as a second contact point 19. Parallel to the first contact point 11 of the parallel-current path 15 is connected, in which the resistance body 16 is arranged. Electrically in series with the resistor body 16 is a not shown in detail in Fig. Selective bimetal 20, which acts on a switching mechanism 21, which is shown in FIG. 1 and on which a switch knob 22 is arranged or articulated. In the main current path 18 is another bimetallic strip 36, which is also not shown in FIG. 1; This bimetallic also acts on the switching mechanism 21, wherein the switching mechanism 21 is connected via the line of action 23 with the contact point 19.

Die Wirklinien der Thermobimetalle 20, 36 auf das Schaltschloß sind mit den Bezugsziffern 24 und 25 bezeichnet.The lines of action of the thermostatic bimetal 20, 36 on the switch lock are designated by the reference numerals 24 and 25.

Die Fig. 2 zeigt eine Schnittansicht gemäß Schnittlinie II- II. Das Gehäuse 10 ist hier aus einem schalenförmigen Gehäuseunterteil 10 a und einem schalenförmigen Oberteil 10 b gebildet, an denen jeweils Leisten 26, 27; 28, 29 angeformt sind, die in der Fig. 1 ebenfalls ersichtlich sind. Durch die Leisten 26 bis 29 wird ein Raum 30 gebildet, in dem der Widerstandskörper 16 untergebracht ist.2 shows a sectional view along section line II-II. The housing 10 is here formed of a cup-shaped housing lower part 10 a and a cup-shaped upper part 10 b, on which respective strips 26, 27; 28, 29 are formed, which are also visible in FIG. 1. Through the strips 26 to 29, a space 30 is formed, in which the resistance body 16 is housed.

Die Kontaktierung des Widerstandskörpers 16 erfolgt mittels Flachbandleitern 31 und 32, die den Parallelstrompfad bilden und in den Fig. 3 und 4 näher dargestellt sind.The contacting of the resistor body 16 by means of ribbon conductors 31 and 32, which form the parallel-current path and are shown in more detail in Figs. 3 and 4.

Bei der Ausführung gemäß Fig. 3 ist der Leiter 31 als gerades Bauteil ausgebildet, wogegen der Leiter 32 im Bereich der Kontaktierungsfläche 16 a des Widerstandskörpers 16 einen zur Kontaktierungsfläche 16 a konvexen Abschnitt 33 aufweist.In the embodiment according to FIG. 3, the conductor 31 is designed as a straight component, whereas the conductor 32 in the region of the contacting surface 16 a of the resistance body 16 has a contact surface 16 a convex portion 33.

Bei der Ausführung gemäß Fig. 4 ist anstatt des geradlinig ausgebildeten Leiters 31 ein solcher 31 a verwendet, der einen zur Kontaktierungsfläche 16 b des Widerstandskörpers 16 hin konvexen Abschnitt 33 a aufweist.In the embodiment of FIG. 4, instead of the rectilinear conductor 31, such a 31 a is used, which has a convex portion 33 a for contacting surface 16 b of the resistance body 16 out.

Wenigstens einer der beiden Leiterstücke 31, 32 ist federnd. Bei der Ausführung gemäß Fig. 3 ist dies der Leiter 32, wogegen bei der Ausführung gemäß Fig. 4 auch der Leiter 31 a federnd ausgebildet ist.At least one of the two conductor pieces 31, 32 is resilient. In the embodiment of FIG. 3, this is the conductor 32, whereas in the embodiment of FIG. 4, the conductor 31 a is formed resiliently.

Wie aus Fig. 1 ersichtlich ist, kann der Leiter 32 so geformt sein, daß er mit einer Abkröpfung 34 und einer Abkantung bzw. Abwinkelung 35 den Widerstandskörper 16 festhält.As can be seen from Fig. 1, the conductor 32 may be shaped so that it holds the resistance body 16 with a bend 34 and a bend or angling 35.

Das hierbei verwendete Material, das oben angegeben ist, besitzt einen Themperaturkoefizienten, der etwa konstant bzw. geringfügig negativ ist. Der Grund liegt in folgendem:

  • Wenn der Schalter gemäß Fig. 5 einen Kurzschluß abschalten soll, dann wird über einen magnetischen Auslöser 40 zunächst die Kontaktstelle 11 geöffnet, und zwar über die Wirklinie 41. Dabei wird dann der Strom in den Parallelstrompfad komutiert und durch den Widerstandskörper 16 begrenzt, wobei die Kontaktstelle 19 noch geschlossen ist. Der durch den Widerstand 16 begrenzte Strom durchfließt die Spule 40 und
  • hält damit die Kontaktstelle 11 offen. Wenn nun in einem nachgeordneten Leitungsschutzschalter der Kurzschluß abgeschaltet wird, dann schließt die Kontaktstelle 11; wenn der Strom nicht abgeschaltet wird, erwärmt sich das Thermobimetall 20 bzw. 22 und schaltet auf diese Weise die Kontaktstelle 19 endgültig ab. Es wird in diesem Zusammenhang auf die eingangs erwähnte DE 28 54 711 und auf den eingangs erwähnten Schalter S 700 verwiesen.
The material used herein, given above, has a temperature coefficient which is approximately constant or slightly negative. The reason lies in the following:
  • If the switch according to FIG. 5 is to switch off a short circuit, the contact point 11 is first opened via a magnetic release 40, specifically via the line of action 41. In this case, the current is commutated into the parallel current path and limited by the resistance body 16, wherein the Contact point 19 is still closed. The current limited by the resistor 16 flows through the coil 40 and
  • keeps the contact point 11 open. If now in a downstream circuit breaker the short circuit is turned off, then closes the contact point 11; if the power is not turned off, the bimetallic 20 or 22 is heated and in this way the contact point 19 finally off. In this context, reference is made to the initially mentioned DE 28 54 711 and to the switch S 700 mentioned in the introduction.

Wenn nun der Widerstandskörper 16 einen positiven Temperaturkoefizienten hätte, dann würde der Strom soweit begrenzt, daß der Anker des Auslösers 40 abfällt und die Kontaktstelle 11 schließt, was ungünstig wäre. Aufgrund des etwa konstanten bzw. negativen Temperaturkoefizienten bleibt der Strom durch den Auslöser 40 gleich bzw. wird geringfügig größer, wodurch die Kontaktstelle ausreichend lange in Öffnungsstellung gehalten werden kann.Now, if the resistor body 16 had a positive temperature coefficient, then the current would be limited so far that the armature of the trigger 40 drops and the contact point 11 closes, which would be unfavorable. Due to the approximately constant or negative temperature coefficient, the current through the trigger 40 remains the same or is slightly larger, so that the contact point can be kept sufficiently long in the open position.

Es ist erwähnt worden, daß der Widerstandskörper aus einer mit Kohlenstoff dotierten Keramik bestehen kann; es gibt auch die Möglichkeit, ein mit Kohlenstoff dotiertes Siliziumkarbit zu verwenden. Des weiteren kann der Widerstandskörper 16 auch mit anderen leitfähigen Materialien dotiert sein. Außerdem kann der Widerstandskörper je nach Bedarf jede beliebige Form, z. B. Zylinder-, Hohlzylinder-, Würfel- oder Prismaform aufweisen.It has been mentioned that the resistor body may be made of a carbon-doped ceramic; there is also the possibility to use a carbon carbide doped silicon carbide. Furthermore, the resistor body 16 may also be doped with other conductive materials. In addition, the resistance body as needed any shape, eg. B. cylinder, hollow cylinder, cube or prism shape.

Es sei noch ergänzt, daß dann, wenn die Stirnseiten des Widerstandkörpers 16 metallisiert sind, die Leitungsstücke 31 und 32 direkt aufgelötet werden können.It should be added that when the end faces of the resistor body 16 are metallized, the pipe sections 31 and 32 can be soldered directly.
