High and low voltage switchgear is used in power system transmission and distribution, power generation, electric energy rotary ring and consumption to play the role of protection, control and pain off, and high voltage switchgear refers to the voltage in 3.6 kV to 550 kV electrical products, it has bus contact, overhead incoming and outgoing lines and cable incoming and outgoing lines and other major functions, it is mainly used in power plants, factories and mines, substations, residential areas, petrochemicals, high-rise buildings, metallurgical steel rolling and light industrial textile industries.

1 What isHigh and low voltage switchgearWhat?

High and low voltage switchgearIt is used in power system transmission and distribution, power generation, power rotation ring and consumption to play the role of protection, control and pain interruption, and high-voltage switchgear refers to the voltage of 3.6 kV to 550 kV electrical products, it has bus contact, overhead incoming and outgoing lines and cable incoming and outgoing lines and other major functions, it is mainly used in power plants, factories and mines, substations, residential areas, petrochemicals, high-rise buildings, metallurgical steel rolling and light industrial textile industries.

2. Composition

It mainly consists of two parts: circuit breaker and cabinet.

① The cabinet material is made of cold-rolled steel plate, galvanized steel plate, stainless steel plate, aluminum plate, main bus room, circuit breaker room, cabinet top small bus room, cable room, relay instrument room, etc.

② Electrical components are composed of current transformers, voltage transformers, high-voltage contactors, high-voltage circuit breakers, high-voltage live displays, transformers, lightning arresters, grounding switches, isolating switches, high-voltage fuses, insulators, high-voltage reactors, voltmeters, and air switches, Signal lights, microcomputer integrated protection devices, etc.
