The functions of high voltage switchgear

What are the functions of high voltage switchgear?

With the constant changes of the times, our lives are constantly going uphill. Think about it, we used to use candles for lighting, but now we use electricity for lighting. High-voltage wires and high-voltage electrical boxes can be seen everywhere on the street. Well, today I want to talk about high-voltage switchgear with you. How much do you know about high-voltage switchgear? What is the function of high-voltage switchgear? If you don’t know, follow me to find out

What is a high-voltage switchgear?

High-voltage distribution cabinets can also be called high-voltage switch cabinets, which refer to electrical products that are used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, and the voltage level is 3.6kV~550kV , mainly including high-voltage circuit breakers, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices and high-voltage switchgears. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry, and occupies a very important position in the entire power industry. the

The function of the switch cabinet:

The function of the switchgear is to break the high-voltage circuit, and it is the main equipment of the high-voltage switchgear. The bus bar and the cable are used to realize the connection. Generally, the bus bar is connected to the system side, which is equivalent to the source of high voltage, and then connected to the cable through the switch. The load carried by the cable connection switch. It can be a transformer, a motor or other equipment.

Composition of switchgear:

The switchgear should meet the relevant requirements of the GB3906-1991 "3-35 kV AC metal-enclosed switchgear" standard. It is composed of two parts: a cabinet body and a circuit breaker, and has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. The cabinet is composed of housing, electrical components (including insulating parts), various mechanisms, secondary terminals and wiring.
