The Classification Of Switch Cabinet

Dec. 21, 2018

The Switch Cabinet is an electrical device. The external 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 instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., some also have high-voltage room and Low-voltage Switch Cabinet   with high-voltage busbars, such as power plants, and some also have low-cycle to protect the main equipment. Load reduction.

The main function of the switchgear is to open, close, control and protect the electrical equipment during the power generation, transmission, distribution and power conversion of the power system. The components in the switchgear are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many classification methods for switchgear. For example, the switchgear can be divided into Movable Switch Cabinet and fixed switchgear. Or according to the structure of the cabinet, it can be divided into open switchgear, metal-enclosed switchgear, and Metal Armored Switch Cabinet; according to different voltage levels, it can be divided into high voltage switchgear, medium voltage switchgear and low voltage switchgear. It is mainly used in power plants, substations, petrochemicals, metallurgical rolling mills, light industrial textiles, factories and mines, residential quarters, high-rise buildings and other different occasions.
