Electric leakage protector with automatic power supply and power off functions

Abstract

The invention discloses an electric leakage protector with automatic power supply and power off functions. The electric leakage protector comprises a shell and pins, elastic sheets and a self-lock device which are arranged in the shell. The pins and the elastic sheets are respectively provided with pin contacts and elastic sheet contacts which can be mutually closed. The self-lock device comprises a transverse stop block hinged with a pin base, a release base with a release relay, and a self-lock rod which is hinged with a reset base with the release relay and hinged with the release base. When power supply recovers, the reset push rod of the release relay controls the transverse stop block to rotate relative to the pin base in an anticlockwise way so that the pressing ends are enabled to press the elastic sheets and the elastic sheet contacts are enabled to be contacted with the pin contacts to realize electrification; and when power is off, the release push rod of the release relay controls the self-lock rod to rotate relative to the release base in a clockwise way so that the locking notch is enabled to be separated from the locking end and limitation of moving of the pressing ends in locking can be relieved, and the elastic sheet contacts can be separated from the pin contacts to realize power off. The safety hidden trouble caused by abnormity of a ground wire can be avoided so that use is quite safe.

Description

technical field [0001] The invention relates to the field of electrical protection equipment, in particular to a leakage protector with automatic power supply and power-off functions. Background technique [0002] The traditional three-wire PE disconnectable leakage protector has realized that the power supply socket E (ground wire) will be cut off immediately after the power supply is charged, and the tripping protection function of "abnormally charged ground wire" has been realized. The leakage protector is a combination of machinery and electronics. The effective prerequisite for realizing the leakage protection function is that the leakage protector should have a normal power supply voltage. In actual use of products with leakage protectors, quite a few users use the switch on the socket to cut off the power supply of the leakage protector. The biggest potential safety hazard of this operation is: when the ground line is abnormal, the charged leakage protector The devic...
