Description

Technical Field

[0001] The invention relates to the technical field of leakage detection, in particular to a circuit emergency protection device for leakage detection equipment. Background Art

[0002] Leakage is caused by a certain potential difference between the electrical appliance casing and the mains live wire and the ground after they are connected for some reason. The best way to detect leakage is to touch the charged part with a test pen. If the neon bulb lights up and then goes out immediately, it proves that the charged part is carrying static electricity. If it stays on for a long time, it is definitely a leakage. Even if there is no problem with the circuit board of the appliance itself, leakage may occur due to leakage of certain components or because the circuit board is damp or dusty. For example, some electrical appliances have no charge on the casing at first, but become charged again after a period of use. This is mostly the case.

[0003] Most of the existing leakage detection devices are not equipped with backup circuits. As a result, when the leakage detection device is damaged, the staff cannot replace the circuit in time, which may cause the power system to trip frequently or have an unstable operating state.
