Leakage protector with phase line switching function

Номер: CN102623947A
Автор: Jin Hai, Zhang Jifu, Lin Shengde, Wang Shigang
Принадлежит:

The invention discloses a leakage protector with a phase line switching function, which comprises a current transformer and a three-phase current detection circuit. The current transformer is used for detecting leakage current and outputting a leakage signal. The output end of the current transformer is connected with an amplifying circuit, and the amplifying circuit amplifies the leakage signal and inputs the signal into a single chip. The current detection circuit is connected with a current signal receiving circuit, a three-phase current signal receiving circuit inputs a current signal into the single chip, the current signal receiving circuit is used for receiving a three-phase current signal, the output end of the single chip is connected with a driving circuit in driving connection with a switch in a three-phase line, the driving circuit is connected with the input end of the single chip through a feedback circuit, the feedback circuit inputs a driving signal of the driving circuit ...
