technical field

The utility model relates to the field of electric equipment, in particular to an outdoor ventilation and dustproof power cabinet.

Background technique

Once 800KV, 500KV and other distribution stations are put into operation, for safety reasons, the doors of high-voltage cabinets are rarely opened, and most high-voltage cabinets adopt a sealed design. The accumulation of gas will cause partial discharge, which will cause safety hazards to the operation of equipment. Especially in July and August, the climate is humid, and accidents caused by discharge caused by humid air are not uncommon. Furthermore, the equipment in the high-voltage cabinet releases heat during the working process. How to cool down the inside of the power cabinet while dehumidifying is a problem. The power cabinet only needs a normal temperature environment, not a low temperature environment, so it is not necessary to design according to the conditions of a refrigerator; the air conditioner seems to be able to meet the requirements, but the compressor is placed in the cabinet, which obviously occupies a large volume in the cabinet. It is very inconvenient to move and relocate the power cabinet if it is placed outdoors.

Patent No. CN204696506U discloses a dust-proof and moisture-proof power cabinet, including an upper cabinet and a lower cabinet, the upper cabinet and the lower cabinet are fixedly connected, and ventilation holes are provided on both sides of the inner wall of the upper cabinet , the ventilation hole is provided with a dust-proof device, the dust-proof device includes a dust-proof net and a desiccant, and a desiccant is sandwiched in the dust-proof net, a cooling fan is installed on the ventilation hole, and the lower cabinet body The connection with the upper cabinet is provided with a first moisture-proof layer, and the bottom of the lower cabinet is provided with a second moisture-proof layer. The power cabinet has large volume, unstable operation, high noise and inconvenient maintenance.
