Switchgear (Switch cabinet ) Is an electrical equipment, switchgear outside the first into the cabinet master switch, and then enter the sub-control switch, according to their needs to set the branch. Such as instrumentation, automatic control, motor magnetic switch, Also set up high-pressure chamber and low-voltage switch cabinet, with high-voltage bus, such as power plants, and some also have to protect the main equipment for low-load reduction.

Switchgear (Switchgear ) Is the main role in the power system for power generation, transmission, distribution and energy conversion process, the opening and closing, control and protection of electrical equipment. Switchgear Within the main components breaker , Isolation switch , Load switch , Operating mechanism, the transformer and a variety of protection devices and other components. Switchgear Many of the classification methods, such as through breaker Installation can be divided into removable Switchgear And fixed Switchgear ; Or in accordance with the different cabinet structure can be divided into open switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear; according to different voltage levels can be divided into high-voltage switchgear, medium voltage switchgear and low voltage switch Cabinets, etc. Mainly used in power plants, substations, petrochemical, metallurgical rolling, light industry and textile, factories and mines and residential quarters, high-rise buildings and other different occasions.
