Description

technical field [0001] The invention relates to a detection device, in particular to an electrostatic inspection device. Background technique [0002] The function of the grounding device is mainly to prevent personal electric shock, damage to equipment and lines, prevent fire and lightning strikes, prevent electrostatic damage and ensure the normal operation of the power system. It is an important part of the power system. Whether it is strong current equipment or weak current equipment, whether it is high voltage equipment or low voltage equipment, whether the grounding device is qualified or not will directly affect the normal and safe operation of the system and equipment. Once the electrical equipment is poorly grounded, the accumulation of a large amount of static electricity will pose a threat to the equipment and staff; and when the static electricity reaches a certain value, it may cause equipment failure or even fire due to electrostatic discharge, resulting in irr...

Problems solved by technology

Electrical equipment is widely distributed, from cities to towns, from indoors to outdoors. If regular testing is carried out by manually measuring the grounding resistance, on the one hand, a lot of manpower, material resources and time will be wasted. On the other hand, due to the failure of the grounding device With great chance and randomness, it is impossible to monitor in real time
