Switch cabinet is a kind of electrical equipment, the outside of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instrument, automatic control, motor magnetic switch, all kinds of AC contacters, etc., some also set up high voltage chamber and low voltage chamber switch cabinet, with high voltage bus, such as power plant, etc., some also have low cycle load reduction for the main equipment.

The main function of the switch cabinet is to open and close, control and protect the electrical equipment in 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 breaker, isolating switch, load switch, operating mechanism, transformer and various protective devices.

There are many classification methods of switchgear, such as circuit breaker installation can be divided into removable switchgear and fixed switchgear; Or according to the different structure of the cabinet, it can be divided into open switch cabinet, metal closed switch cabinet, and metal closed armored switch cabinet; According to different voltage levels can be divided into high voltage switchgear, medium voltage switchgear and low voltage switchgear.

Mainly suitable for power plants, substations, petrochemical, metallurgical steel rolling, light industry textile, factories and mining enterprises and residential areas, high-rise buildings and other different occasions.
