Abstract

The invention provides an electric leakage tripping device and leakage circuit breaker containing the tripping device. The electric leakage tripping device comprises: base, sensor unit, tripping putter and button component. The button components can be set at the base movably along pressing direction , including pressing points and the main part connected fixedly to pressing part, and the base is set up with reset button providing force on button component opposing from pressing direction; the tripping putter is equipped with partial pressure unit providing force along reset direction and the limiting part, while main part is buckling with clamp part coordinating with limiting part which buckles with limiting part in tripping status and release the engagement in reset status; self-reset putter interacts with the switching mechanism of leakage circuit breaker, suitable for making pressing button components of the self-reset putter moves along pressing direction when leakage circuit breaker changes from tripping status to re-buckling status. The electric leakage tripping device not only can re-buckle automatically but also manually, with simple structure and quick reset function.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a leakage tripping device and a leakage circuit breaker including the leakage tripping device. Background technique [0002] As an important switching device in low-voltage electrical appliances, leakage circuit breakers are widely used in electrical circuits. They can protect people when they get an electric shock, and can also prevent fires caused by ground fault currents generated by electrical equipment due to insulation damage. Danger. As the most important part of the leakage circuit breaker, the leakage release can automatically trip the circuit breaker and disconnect the circuit when there is a leakage in the circuit, thus protecting personal safety, and the alarm function can effectively prompt the equipment management personnel to find the fault as soon as possible And ruled out, so that the device returns to normal operation as soon as possib...
