Abstract

Die Erfindung betrifft eine elektrische Anordnung zum Ansteuern parallel betriebener Schütze. Das zu lösende Problem besteht darin, auszuschließen, dass von mehreren parallel betriebenen Schützen (1; 2) nur einzelne sich im eingeschalteten Zustand befinden. Dazu ist eines der Schütze (1) mit einer elektronischen Antriebssteuerung (AS) versehen, welche die Magnetantriebe (K1; K2) aller Schütze (1; 2) steuert, und mit zwei hochstromigen Steuereingängen (A1; A2) sowie mit zwei niederstromigen Steuereingängen (A10; A11) ausgestattet, die mit den hochstromigen Steuereingängen (A1; A2) widerstandsbehaftet verbunden sind. Die niederstromigen Steuereingänge (A10; A11) werden durch seriell verbundene, nach Erreichen einer voreingestellten Grenztemperatur öffnende Thermoschalter (TS1; TS2) überbrückt, die jeweils einem der Schütze (1; 2) zugeordnet und mit wenigstens einer der internen Hauptstromschienen (S13; S21) des jeweiligen Schützes (1; 2) thermisch gekoppelt sind.

The invention relates to an electrical arrangement for driving parallel-operated contactors. The problem to be solved is to exclude that of several parallel operated contactors (1; 2) only a few are in the on state. For this purpose, one of the contactors (1) is provided with an electronic drive control (AS), which controls the magnetic drives (K1, K2) of all contactors (1, 2), and with two high-current control inputs (A1, A2) and with two low-current control inputs ( A10; A11), which are connected resistively to the high-current control inputs (A1; A2). The low-current control inputs (A10, A11) are bridged by serially connected thermal switches (TS1, TS2) opening after reaching a preset limit temperature, each associated with one of the contactors (1, 2) and connected to at least one of the internal main busbars (S13, S21). of the respective contactor (1; 2) are thermally coupled.
