Abstract (en)

The invention relates to an operating device intended for high-voltage circuit breakers and comprising an operating shaft (11) which influences an operating lever (13) connected to the movable contact (15) of the circuit breaker. The operating device comprises a closing spring (16) and an opening spring (28). After each completed closing operation, a motor tensions the closing spring (16) again, and the closing spring tensions the opening spring (28) upon closing of the circuit breaker. The closing spring is kept tensioned by a closing latch. The breaker contact (15) is kept closed and the opening spring (28) is kept tensioned by a tripping latch (27). The operating lever (13) is provided with a spring-loaded catch flap (40) which cooperates with the fixedly mounted tripping latch (27). The catch flap has the shape of a substantially rectangular plate, one edge portion of which is designed to serve as a rotary shaft and is rotatably fixed to a bearing seat formed in the operating lever (13). <IMAGE>
