Abstract

PURPOSE: To promote the preventive operation for a power interruption fault in an overall scale, by detecting a state of use of the appliance connected to the socket with a power supply partially or totally ceased to the socket on the basis of this detection.
CONSTITUTION: To a plug 11 are connected a parallel circuit of sockets 12, 13 and an input end of rectifying bridge 16, and in the socket 12 is provided a normally close contact 171 of a relay 17 for disconnecting the power supply. In the socket 13 is provided a current transformer CT14, for generating an output according to its flow of current, with its output end connected to an input end of reactifying bridge 15. To the CT14 is also connected a variable resistance 23 in parallel, and to the positive side output end of the bridge 15 is connected a gate G of SCR18 through a resistor 25, and to the negative side output end connected a cathode K. Across the gate G and the cathode K, are connected in parallel a Zener diode 19, a resistor 26 and a condenser 22. In this way, the preventive operation can be made for an overall power interruption fault when connected appliances of overcapacity.
