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 sowohl durch eine Zeitschaltung (TS), die beim Anlegen eines Steuersignals an den hochstromigen Steuereingängen (A1; A2) von einem hochohmigen für eine bestimmte Haltedauer in einen niederohmigen Zustand übergeht, als auch durch seriell verbundene und durch die Schütze (1; 2) betätigte Schließerhilfskontakte (HI1; HI2) überbrückt. 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 both by a timing circuit (TS), which passes when applying a control signal to the high-current control inputs (A1, A2) of a high-impedance for a certain holding period in a low-resistance state, as well as by serially connected and bridged by the contactors (1; 2) operated auxiliary closing contacts (HI1, HI2).
