Description

TECHNICAL FIELD

[0001] The utility model relates to a switchgear equipment technical field especially relates to a novel high voltage switchgear. BACKGROUND

[0002] The high voltage switchgear is the key equipment for controlling, protecting and distributing high voltage electric energy in the power system, and the main functions include: control function, protection function, monitoring function, and is widely used in power generation, power transmission, power distribution and other fields.

[0003] In the existing high voltage switchgear, in order to improve the heat dissipation efficiency, heat dissipation fan is usually installed in the cabinet to enhance the circulation of air inside and outside the cabinet, so that better heat dissipation effect is realized. However, with the passage of time, dust and other solid particles will flow into the cabinet body along with the air flow, and adhere to the circuit breaker, isolating switch and other components. After long-term accumulation, these dusts not only seriously affect the heat dissipation performance of the equipment, but also cause damage to the components, and even may cause the equipment to be unable to operate normally, and there are short circuit, fire and other safety hazards. In order to solve this problem, some equipment will install filter screen at the air inlet to block the dust from entering. But this filter screen needs to be replaced regularly, and when replacing, the cabinet door usually needs to be opened. Because there are a large number of components in the cabinet in the state of power on, such disassembly and assembly operation is not only extremely inconvenient, but also may increase the operation risk.
