Title:
回路遮断器用検出回路
Document Type and Number:
Japanese Patent JP5837645
Kind Code:
B2
Abstract:
The present disclosure relates to a detecting circuit for a circuit breaker (10), comprises: a detection sensor (20) configured to output a detection signal by detecting a voltage or a current on an alternating current electric power circuit; a low pass filter (30) configured to output a signal from the detection sensor after removing a high frequency component from the signal; an offset remover (40) configured to output a signal from the low pass filter after removing a direct current offset from the signal; an amplifier (50) configured to amplify a signal from the offset remover, and to output the signal; and a comparator (100) configured to output a breaking control signal such that the circuit breaker operates to a circuit breaking position, if the detection signal input to the amplifier is equal to or larger than a reference voltage.
