Sand-storm-proof heat dissipation switch cabinet

Abstract

The invention relates to the field of substation switch cabinets, in particular to a sand-storm-proof heat dissipation switch cabinet, which comprises a device body. Device side plates are movably mounted on the left and right sides of the device body; outer air inlet channels are formed in the device side plates; connecting rods are fixedly connected to the two sides in the device body; a knocking plate and a sand scraping plate are movably mounted on a rotating shaft at the lower ends of the connecting rods; when a motor drives a rotating wheel to rotate in a rotating wheel cavity, the device side plates can be intermittently driven to move up and down through the shape of the rotating wheel, so that the positions of the inner air inlet channels and the outer air inlet channels can be continuously switched between opposite communication and staggered non-communication; and meanwhile, the lower end of the sand scraping plate communicates with the upper end of the outer air inlet channels, and when the device side plates move upwards and the outer air inlet channels and the inner air inlet channels are staggered in position, the sand scraping plate under the connecting rod with thefixed position can scrape off sand and dust blocked by an outer side filter screen, so that the effect of intermittently cleaning the outer side filter screen is achieved, and the situation that theouter side filter screen is rapidly blocked in a sand and dust storm, and air flow cannot be introduced into the interior is avoided.

Description

technical field [0001] The invention relates to the field of substation switch cabinets, in particular to a sandstorm-proof heat dissipation switch cabinet. Background technique [0002] Isolation switch is a switching device that is mainly used for "isolation of power supply, switching operation, and connecting and cutting off small current circuits". It has no arc extinguishing function and is widely used in power systems. The wind and sand are relatively serious. As one of the important electrical equipment in the substation, the isolating switch is usually installed in the isolating switch operating mechanism box in order to reduce the impact of the external environment and protect the isolating switch. [0003] However, most of the isolating switch operating mechanism boxes on the market currently lack corresponding protective devices against sandstorms in the western region, so that the insulation is not completely sealed and the interior cannot be fanned, or the vents...

Problems solved by technology

[0003] However, most of the isolating switch operating mechanism boxes on the market currently lack corresponding protective devices against sandstorms in the western region, so that the insulation is not completely sealed and the interior cannot be fanned, or the vents are quickly blocked in sandstorms, thereby greatly reducing the protection of the substation switch operation box. efficiency
