Description of drawings:
Fig. 1 is circuit theory diagrams of the present utility model.
Specific embodiments:
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
CZ among Fig. 1 is the alternating current Three-hole socket, and electric-leakage detection circuit is connected across between socket ground wire mesopore and the zero line jack.The casing for electric appliances of leakproof insulate, promptly, the potential difference between zero line just is zero.If there is electric leakage electrical equipment to insert thereon, just leakage current can constitute the loop by the mesopore of CZ and through 1,2 pin of self-resetting switch AN1, R1, optocoupler 4N25 and diode 1N4004 and electrical network zero line.Coupling by 4N25 makes unidirectional controllable silicon S CR conducting, and the relay J action disconnects its normally-closed contact J1, J2, and socket stops electric power supply, reaches the purpose of protection.D2 is a LED strobe light emission diode BTS11405, as long as energized, it just can flash, call user's attention.IC2 adopts language integrated circuit HFC5219, and it adopts level triggering mode, in case get electric triggering, just sends the voice signal of " electricity is arranged, and Danger!
