DISPOSITIVO MEJORADO PARA ACCIONAR UN INTERRUPTOR DE CIRCUITO ELECTRICO |
摘要 |
An operating device for an electric circuit breaker comprises a closing spring and a rotatable spring-controller mounted for rotation between first and second dead-center positions with respect to the spring. The spring is charged by transmitting rotational forces to the spring-controller through a pawl mounted on the spring controller and an abutment on a rotatable driving member. Cam means is provided for releasing the pawl from driven engagement with the abutment at the end of a spring-charging operation. Circuit-breaker closing is effected by allowing the spring quickly to discharge after a charging operation. |
