Control apparatus and control method for residual current circuit breaker

摘要

The present invention provides an apparatus for the control of a residual current circuit breaker, which comprises: an amplifying unit for receiving a detected electrical leakage sampling signal and outputting a first output signal after having amplified said electrical leakage sampling signal; a delay unit for outputting a second output signal in the case of receiving said first output signal, wherein after a predetermined time delay started from the receipt of said first output signal, said second output signal reaches a first predetermined value; a triggering unit for outputting a triggering signal for triggering the action of an actuating mechanism in said residual current circuit breaker in the case of said second output signal reaching the first predetermined value. The present invention further provides a method for the control of the residual current circuit breaker.
