Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and more specifically to an intelligent detection device for safe electricity use. Background Art

[0002] During use, electrical equipment may have leakage due to poor grounding or other faults. After the equipment leaks, a large amount of charge will accumulate on the device casing and gradually move to the sharp part of the casing to discharge (tip discharge). After the equipment leaks, the discharge position is not easy to be detected, so when the human body is close to the equipment, it is easy to get an electric shock. When there is flammable gas around the electrical equipment, the flammable gas is easy to burn or even explode under the action of the charge, which poses a great safety hazard. Therefore, designing a solution that can actively detect the leakage of electrical equipment so as to eliminate the safety hazard in time has become an urgent problem to be solved in this field.
