Abstract
Description
Die Erfindung betrifft einen Leistungsschalter, insbesondere einen Hochstromschalter, mit mindestens einer Poleinheit mit einem Polkopf und einem Polträger und einem dazwischen angeordneten Kontaktsystem sowie einer Antriebseinheit zur Einleitung einer Schaltbewegung in einen Bewegkontakt des Kontaktsystems, wobei jeder Polkopf und jeder Polträger der Poleinheit jeweils mittels einer Stützeinrichtung mit zwei nebeneinander angeordneten Stützelementen an einer Haltewand des Leistungsschalter befestigt sind.The Invention relates to a circuit breaker, in particular a high-current switch, with at least one pole unit with a pole head and a pole carrier and an interposed contact system and a drive unit for initiating a switching movement into a moving contact of the contact system, wherein each pole head and each pole carrier of the pole unit respectively by means of a support device with two juxtaposed support elements on a retaining wall the circuit breaker are attached.
Ein derartiger Leistungsschalter ist beispielsweise aus der Siemens Druckschrift „Siemens HG 11.11, 1999" bekannt. Der dort offenbarte Hochstromschalter als Leistungsschalter umfasst drei Poleinheiten mit jeweils einem Polkopf und einem Polträger sowie eine Antriebseinheit zur Einleitung einer Schaltbewegung in einen Bewegkontakt eines Kontaktsystems der jeweiligen Poleinheit. Jeder Polkopf und jeder Polträger mit dem dazwischen angeordneten Kontaktsystem sind mittels zweier nebeneinander angeordneter Stützelementen an einer Haltewand des Leistungsschalters befestigt. Insbesondere bei derartigen Hochstromanwendungen sind für Polkopf und Polträger zwei nebeneinander liegende Stützelemente vorgesehen, um eine ausreichende Stabilität bei den durch die hohen Ströme auftretenden großen Querkräfte auf die Poleinheiten zu gewährleisten.One Such circuit breaker is for example from the Siemens Publication "Siemens HG 11.11, 1999 "known. The high-current switch disclosed therein as a circuit breaker comprises three pole units each having a pole head and a pole carrier and a drive unit for initiating a switching movement in one Moving contact of a contact system of the respective pole unit. Everyone Polhead and each pole carrier with the interposed contact system are by means of two side by side arranged support elements attached to a retaining wall of the circuit breaker. Especially at such high current applications are two for Polkopf and Poltron adjacent support elements provided to ensure sufficient stability in the case of the high currents huge transverse forces to ensure the polar units.
Aufgabe der vorliegenden Erfindung ist es, einen Leistungsschalter der eingangs erwähnten Art weiterzubilden, welcher bei einem konstruktiv einfachen Aufbau über verbesserte Ei genschaften hinsichtlich der Stabilität und der Isolation verfügt.task The present invention is a circuit breaker of the mentioned To further develop type, which improved in a structurally simple structure Properties in terms of stability and insulation features.
Erfindungsgemäß wird die Aufgabe bei einem Leistungsschalter der eingangs erwähnten Art dadurch gelöst, dass die Stützeinrichtung anstelle der zwei Stützelemente einen einzigen einstückig ausgebildeten Isolierkörper umfassen.According to the invention Task in a circuit breaker of the type mentioned by solved, that the support device instead of the two support elements a single one-piece insulator include.
Mit einem derartigen einstückig ausgebildeten Isolierkörper ist eine einfache konstruktive Anordnung gegeben, weil Toleranzen verschiedener Isolierkörper eines Polkopfes oder Polträgers nicht ausgeglichen werden müssen, welche anderenfalls zu einer mechanischen Vorspannung bei der Befestigung führen würden und somit die Lebensdauer des Leistungsschalters herabsetzen würden. Des Weiteren sind die Isolationseigenschaften des Leistungsschalters verbessert, weil durch den einstückig ausgebildeten Isolierkörper kein Zwischenraum zwischen den Isolierkörpern eines Polträgers oder Polkopfes ausgebildet ist, in welchen Zwischenraum ein elektrisches Feld zwischen stromführenden Teilen des Polkopfes bzw. Polträgers und der Haltewand des Leistungsschalters zu Überschlägen und damit zu Fehlfunktionen des Schalters führen könnte. Ferner ist die Stabilität der gesamten Anordnung ebenfalls verbessert, weil durch den massiven Aufbau des einstückigen Isolierkörpers bei Querbeanspruchungen höhere Kräfte durch den einstöckigen Isolierkörper mit seinem Querschnitt mit vergleichsweise großen Abmessungen aufgenommen werden können.With such a one-piece trained insulating body is given a simple constructive arrangement because tolerances different insulator a Polkopf or Polträgers need not be compensated which otherwise leads to a mechanical bias in the attachment to lead would and thus reduce the life of the circuit breaker. Of Furthermore, the insulation properties of the circuit breaker improved because of the one-piece trained insulating body no space between the insulators of a Polträgers or Polkopfes is formed, in which space an electric Field between live Parts of the pole head or Polträgers and the retaining wall of the circuit breaker to flashovers and thus malfunction of the switch could. Further, the stability the whole arrangement also improved because of the massive Structure of the one-piece insulating higher forces at transverse loads personnel through the one-story insulator taken with its cross section with comparatively large dimensions can be.
In einer bevorzugten Ausgestaltung der Erfindung weist die Stützeinrichtung eine metallische Halteplatte auf, welche einerseits an dem Isolierkörper und andererseits an der Haltewand befestigt ist. Mit einer derartigen metallischen Halteplatte wird in einfacher Weise eine Befestigung des Isolier körpers an der Haltewand des Leistungsschalters unter Verteilung der mechanischen Beanspruchung realisiert.In a preferred embodiment of the invention, the support means a metallic retaining plate, which on the one hand to the insulating body and on the other hand fixed to the retaining wall. With such Metallic retaining plate will easily attach of the insulating body the retaining wall of the circuit breaker under distribution of mechanical Stress realized.
In weiterer bevorzugter Ausführungsform sind in dem Isolierkörper der metallischen Halteplatte gegenüberliegend Befestigungselemente zur Befestigung des Isolierkörpers an der Poleinheit vorgesehen. Durch derartige Befestigungselemente ist ein einfacher konstruktiver Aufbau des Leistungsschalters gewährleistet.In Another preferred embodiment in the insulator the metallic retaining plate opposite fasteners for fastening the insulating body provided on the pole unit. By such fasteners is ensured a simple structural design of the circuit breaker.
