Description

Technical Field

[0002] High and low voltage switchgear is a key equipment for realizing control and protection of electrical equipment in power system. It is widely used in power generation, transmission, transformation and distribution. It is mainly used to receive and distribute electric energy, and control, protect and monitor the power system. With the development of modern power system, higher requirements are put forward for the reliability, safety and environmental adaptability of high and low voltage switchgear. High and low voltage switchgear is widely set indoors or outdoors, but no matter where it is set, when it is running, the internal power components will generate high temperature. If the high temperature generated cannot be effectively cooled, it will cause damage to the internal power components and even the high and low voltage switchgear. Existing high and low voltage switchgear often opens vents at the bottom and top of the cabinet, and then uses heat dissipation fan for air cooling. For example, a high and low voltage switchgear with a protective structure in the publication number CN217159022U is used.
