A switchgear with an antistatic device

technical field

The utility model relates to the technical field of electric equipment, in particular to a switch cabinet with a static elimination device.

Background technique

The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors , load switches , operating mechanisms, transformers and various protection devices. There are many classification methods of switch cabinets. For example, according to the installation method of circuit breakers, it can be divided into removable switch cabinets and fixed switch cabinets; or according to the different cabinet structures, it can be divided into open switch cabinets, metal-enclosed switch cabinets, and metal Closed armored switchgear; according to different voltage levels, it can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switchgear.
