The invention relates to an electric leakage protector, in particular to an electric leakage protection device for electromagnetic trip. The electric leakage protection device comprises a shell and main components installed in the shell. The main components comprise a circuit board and a tripper mechanical structure component. A circuit of the circuit board is used for detecting electric leakage and an overvoltage signal and sending a signal to control an electromagnetic trip component to move. The tripper mechanical structure component mainly comprises a main base, two groups of movable contact wafers and static contact wafers, a trip plate and a push-pull rod, wherein the main base is fixed to the circuit board. The electric leakage protection device is used for electric protection, when it is detected that electric leakage happens, a tripper is disconnected, and therefore the safety of a user is ensured.
Description
technical field [0001] The invention relates to a leakage protector, in particular to a leakage protector with electromagnetic tripping. Background technique [0002] The leakage protection device is used in electrical protection. When a leakage is detected, the release will be disconnected to ensure user safety. Leakage protection devices usually have a reset mechanism for resetting the release, a testing mechanism for testing leakage protection, and some also have a manual tripping mechanism for manual tripping. Patent Publication No. 201673875U discloses a leakage protection device, which detects the leakage current through the leakage protection circuit board, so that the tripper performs a tripping action. This leakage protection device has the functions of reset, test and manual tripping, but its disadvantages are: 1. The structural design of the tripper has deficiencies and causes the tripping life to be short. 2. The circuit design of the leakage protection circuit...
