High voltage switchgear is usually composed of main electrical components such as cabinet body, circuit breaker, isolation switch, transformer, lightning arrester, etc. The cabinet is usually made of cold-rolled steel plate or aluminum zinc coated steel plate, which has the characteristics of high protection level, corrosion resistance, dust and water resistance. The interior of the cabinet is divided into multiple functional units, such as the main busbar room, circuit breaker room, cable room, relay room, etc., to facilitate equipment installation and maintenance.

In modern power systems, high-voltage switchgear plays a crucial role. As a key equipment for power transmission and distribution, high-voltage switchgear carries the important mission of ensuring the stable operation of the power system and protecting equipment from damage. This article will provide you with a detailed introduction to the functions, structures, applications, and importance of high-voltage switchgear. Isolation switches can achieve isolation between the power supply and the load, ensuring personnel safety during equipment maintenance or repair.
