Description

Technical Field

[0001] This utility model relates to the field of power distribution switchgear technology, specifically a high-voltage power distribution switchgear. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for power generation, transmission, distribution, power conversion, and consumption, which play a role in switching, control, or protection. The voltage level ranges from 3.6kV to 550kV. It mainly includes several categories such as high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage explosion-proof distribution devices, and high-voltage switchgear. High-voltage switchgear occupies a very important position in the entire power industry.

[0003] Existing high-voltage switchgear typically uses air inlets and cooling fans 14 to dissipate heat inside the switchgear, ensuring the normal operation of the equipment inside. However, in actual use, when air enters through the air inlet, it easily carries away external dust, causing a large amount of dust to accumulate on the dust filter at the air inlet, resulting in blockage of the dust filter, affecting the heat dissipation effect. Furthermore, cleaning the dust filter is quite troublesome and cannot be replaced, leading to poor performance in actual use. Utility Model Content
