Abstract
The utility model discloses an electric leakage overcurrent protection socket, include and be used for responding to whether the single line exists the electric leakage to ground electric leakage induction coil to reach the drop relay for the control circuit break -make, when the single line electric leakage appears to ground, the disconnection of circuit control system control drop relay, supply interruption. Thereby carry out real -time detection to the circuit and realize immediate power -off protection through setting up electric leakage induction coil, electric current mutual inductor and voltage transformer. Because when not using the socket, the socket break off usually, only just manually during normal use open drop relay circular telegram then, therefore reduced the danger of electric shock. Stop the danger of electric leakage: need the manual drop relay of opening just can get an electric shock when people's physical contact list live wire, the circuit control system stops the auto -power -off to get an electric shock when nevertheless getting an electric shock. Stop to overflow the conflagration that arouses. It is energy -concerving and environment -protective, the extension circuit control life of system.
