A heat dissipation switch cabinet against sandstorm

Abstract

The invention relates to the field of substation switchgear, in particular to a heat dissipation switchgear for preventing sandstorms, including a device main body, device side plates are movably installed on the left and right sides of the device body, and an external air inlet is opened inside the device side plate. The side is fixedly connected with a connecting rod, and the rotating shaft at the lower end of the connecting rod is movably installed with a knocking plate and a sand scraping plate. When the motor drives the runner to rotate in the runner chamber, the shape of the runner can intermittently drive the side plate of the driving device to move up and down. , so that the position of the inner air inlet and the outer air inlet can be constantly switched between relative communication and interlocking. When the positions of the air inlet and the inner air inlet are staggered, the sand scraper under the fixed connecting rod can scrape off the sand and dust blocked by the outer filter to achieve the effect of cleaning the outer filter intermittently, thereby preventing the outer filter from being damaged by sandstorms. The air is quickly blocked and airflow cannot be introduced into the interior.

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
