Dustproof structure for power distribution cabinet and use method thereof

Abstract

The invention discloses a dustproof structure for a power distribution cabinet. The dustproof structure comprises a cabinet body, the outside of the cabinet body is hinged with a cabinet door, a firstpartition plate is fixedly connected with the upper side in the cabinet body, and a second partition plate is fixedly connected with the lower side in the cabinet body; a blast blower is arranged atthe upper side the first partition plate, and two sides of the lower side of the first partition plate are fixedly connected with support rods; a sprayer is arranged at one end of each support rod, the output end of the blast blower is communicated with a first connecting pipe, and one end of the first connecting end is communicated to the sprayer; vents are formed at two sides of the cabinet body, and a dustproof net is arranged in each vent. A first switch in the front of the cabinet door is started, a negative pressure fan is connected with an external power supply, the negative pressure fan is operated, the hot air in the cabinet body enters into an air inlet pipe from an air inlet hole through the arrangement of the air inlet pipe and the second connecting pipe, the hot air in the cabinet body is discharged to the external through an exhaust pipe, thereby effectively reducing the temperature in the cabinet body.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a dust-proof structure for a power distribution cabinet and an application method thereof. Background technique [0002] The power distribution cabinet is the power distribution equipment that connects the cables. It is generally used in power supply bureaus and substations, and then it is stepped down by the transformer and then sent to the low-voltage switch cabinet. As we all know, a large amount of dust and suspended particles in the air accumulate, thereby reducing the heat dissipation performance of the internal components of the power distribution cabinet, causing the internal components of the power distribution cabinet to heat up, generating arcs, and reducing the service life of the internal components of the power distribution cabinet. For example, the application number is CN201510198555.6, a high-efficiency dust-proof structure of a power distribution ca...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned dust-proof structure of the power distribution cabinet has the defect that the dust on the filter plate and the multi-filter net is not easy to remove, which will affect the effect of ventilation and ventilation after a long time. Although it can be disassembled, it is also troublesome to manually remove the dust after disassembly. The dust-proof structure used in the power distribution cabinet and its use method solve the above problems
