Outdoor dustproof and waterproof power cabinet

Abstract

The invention provides an outdoor dustproof and waterproof power cabinet which comprises a base (1), a box body (2) is fixed on the base (1), an opening (3) is formed in one side of the box body (2), and the top end of the box body (2) is arranged in an open shape; an outer cover (4) is tightly attached to the outside of the box body (2) in a sliding and sleeved mode, and a movable door (5) is arranged at the position, opposite to the opening (3) in the box body (2), of the outer cover (4); a lifting device is arranged between the top end of the box body (2) and the outer cover (4), an exhaust grille (6) is arranged at the bottom of the box body (2), and an air inlet grille (7) is arranged at the top of the outer cover (4); and the lifting device can drive the outer cover (4) to slide up and down relative to the box body (2). The waterproof and dustproof performance can be improved, the maintenance period is long, and the heat dissipation effect is good.

Description

technical field [0001] The invention relates to outdoor electrical equipment, in particular to an outdoor dustproof and waterproof electric cabinet. Background technique [0002] In order to ensure the power supply and control of the infrastructure of the hydropower station, there are some power cabinets that need to be placed outdoors; in order to ensure the internal heat dissipation effect of conventional power cabinets, cooling grilles are usually set on the surface of the cabinet body, and the overall dustproof and waterproof performance is poor; The outdoor environment is more complicated. When there is strong wind and rainy weather, the dust and moisture from the outside can easily enter the inside of the power cabinet, causing the internal circuit to fail easily, requiring frequent and regular maintenance by the staff (usually about 1 month). Therefore, existing power cabinets have the problems of poor dustproof and waterproof properties and frequent maintenance. Co...

[0002] In order to ensure the power supply and control of the infrastructure of the hydropower station, there are some power cabinets that need to be placed outdoors; in order to ensure the internal heat dissipation effect of conventional power cabinets, cooling grilles are usually set on the surface of the cabinet body, and the overall dustproof and waterproof performance is poor; The outdoor environment is more complicated. When there is strong wind and rainy weather, the dust and moisture from the outside can easily enter the inside of the power cabinet, causing the internal circuit to fail easily, requiring frequent and regular maintenance by the staff (usually about 1 month)

Therefore, the existing power cabinets have the problems of poor dustproof and waterproof performance and frequent maintenance.
