Insect-prevention electrical cabinet body for open air

Abstract

The invention discloses an insect-prevention electrical cabinet body for open air and belongs to the technical field of electrical cabinets. When an existing electrical cabinet is used outdoors, small-size insects can enter the electrical cabinet easily through the gaps of heat dissipation grids, and as a result, the short circuit of a circuit board is easily brought about, and the service life ofthe electric cabinet is influenced, and maintenance cost and labor cost are increased. However, with the insect-prevention electrical cabinet body for open air of the invention adopted, the problemsin the prior art can be solved. An external cabinet body is installed outside an electrical cabinet main body; a built-in cabinet body is installed inside the external cabinet body; heat dissipation grids are arranged at two sides of the built-in cabinet body respectively; the upper end of the external cabinet body is provided with a top plate; the upper end of the top plate is provided with a topbox; and a negative-pressure turbine is arranged at the top end of the interior of the top box.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an insect-proof electrical cabinet for outdoor use. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The materials for electrical cabinets are generally divided into two types: hot-rolled steel plate and cold-rolled steel plate. Compared with hot-rolled steel plate, cold-rolled steel plate is softer and more suitable for electrical appliances. The production of cabinets, electrical cabinets are widely used mainly in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] However, during the external use of the existing electrical cabinet, due to the gaps in the heat dissipation grid, small bugs can easily enter the electrical cabinet, which may easily cause ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an insect-proof electrical cabinet body for outdoor use, so as to solve the problem that small insects can easily enter the electric cabinet due to gaps in the heat dissipation grid during the external use of the existing electrical cabinet proposed in the background technology. In the cabinet, it is easy to cause a short circuit of the circuit board, which affects its service life and increases maintenance costs and labor costs.
