Socket ground wire leakage detection circuit

Abstract

The invention discloses a socket ground wire leakage detection circuit including an oscillator circuit which is composed of a rectification circuit, an optical coupling chip, and a 555 time-base chip and formed through a diode D1, a light emitting diode, and a loudspeaker, The socket ground wire leakage detection circuit can monitor the leakage of household electrical appliances in the use process, sends an acousto-optic alarm if the leakage occurs to warn users to be on an alert and to check the leakage faults after the power off, thereby guaranteeing the personal safety, being simple in circuit, easy to realize and having the good application prospect.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a socket ground wire leakage detection circuit. Background technique [0002] With the rapid development of electronic technology, household appliances have also been widely used. At present, some high-power household appliances, such as washing machines, electric water heaters, refrigerators, air conditioners, etc., may cause leakage due to poor insulation of the shell, which may cause numb hands in mild cases, or cause safety accidents in severe cases, posing potential safety hazards. How to design a socket that can monitor whether household appliances are leaking electricity during use, and can sound and light alarm when there is electricity leakage is an urgent problem that needs to be solved at present. Contents of the invention [0003] The purpose of the invention is to overcome the problem that the existing socket cannot monitor the leakage situation of hou...
