TECHNICAL FIELD
[0001] The present application relates to the technical field of power equipment, in particular to a high-voltage complete switch device. BACKGROUND
[0002] High-voltage complete switch devices play a crucial role in power systems, responsible for safely controlling and protecting power lines. However, during long-term operation, these devices generate a large amount of heat, requiring effective heat dissipation solutions. In this field, the application of existing technology has some obvious deficiencies.
[0003] Existing cooling methods usually rely on forced air flow. Although air cooling can remove some heat in a short period of time, it is insufficient in filtering dust and dirt.

The need for regular cleaning increases labor costs and equipment downtime Although the device introduces a closed-loop circulation design to try to avoid external pollution, this design often relies solely on air for heat exchange. When the external temperature rises, the air flow exchange efficiency in the room significantly decreases. In this case, the temperature inside the device often cannot be effectively controlled, and even causes the device to overload or operate at reduced capacity, which directly affects the safety and reliability of operation in the long term.
