Problems solved by technology

Moreover, none of the existing power distribution cabinets has the function of dust removal. The cabinet is easily invaded by debris such as dust, causing certain inconvenience to the heat dissipation and use of the equipment in the cabinet. In severe cases, it may even cause a short circuit of the computer equipment. and burnt, and the current general dust removal methods are mostly simply blowing with a fan or vacuuming with a vacuum cleaner, which has poor effect, low efficiency, and high labor intensity, which needs to be improved

Abstract

The present invention discloses a power distribution cabinet with functions of heat dissipation and dust removal. A heat dissipation port is arranged on the cabinet body, and the heat dissipation port is composed of a plurality of parallel strip-type heat dissipation holes or a plurality of uniformly-distributed hole-type heat dissipation holes. An exhaust fan is arranged in the cabinet body corresponding to the heat dissipation port. In the cabinet, four air ejector pipes are evenly fixed on the periphery of the exhaust fan and are communicated with the help of an air duct. The air duct communicates with an air pump. The air duct still communicates with a spring pressure boost airbag. The air duct is provided with an electromagnetic switch valve behind the spring pressure boost airbag. The electromagnetic switch valve, the air pump and the exhaust fan electrically connect in series and are connected with a power supply loop of the power distribution cabinet through a dust removal switch. Compared to the prior art, the power distribution cabinet has the better functions of heat dissipation and dust removal.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a power distribution cabinet with the function of heat dissipation and dust removal. Background technique [0002] The power distribution cabinet is a large number of parameters on the data. Generally, it is composed of low-voltage forests. cabinet. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Power distribution cabinet is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution cabinet. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation c...
