The Production Process Of The Switchgear
Mar 15, 2021
The switchgear is a kind of electrical equipment. The outer line 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 instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, equipped with high-voltage busbars, such as power plants, etc., and some also have low-cycle protection for main equipment Load shedding.
The main function of switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, power distribution and electrical energy conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, mutual inductors, and various protection devices. There are many classification methods for switchgear. For example, the installation method of circuit breaker can be divided into removable switchgear and fixed switchgear; or according to the different cabinet structure, it can be divided into open switchgear, metal-enclosed switchgear, and metal Enclosed armored switchgear; according to different voltage levels, it can be divided into high voltage switchgear, medium voltage switchgear and low voltage switchgear. It is mainly suitable for various occasions such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mining enterprises, residential quarters, and high-rise buildings.
