An electrical cabinet with a dehumidification mechanism

Abstract

The invention discloses an electrical cabinet with a dehumidification mechanism. The electrical cabinet comprises a cabinet body and a cabinet door hinged to one side of the cabinet body; a pluralityof heat dissipation holes are formed in the rear side wall of the cabinet body, and a wiring port is formed in the side wall of one end of the cabinet body; supporting legs are fixed at the four corners of the bottom end of the cabinet body; an air discharging opening and an air extracting opening are formed in the upper end and the lower end of the side wall of the cabinet body respectively; theouter side of the air extracting opening is communicated with a dehumidification box, and a fixed frame is further fixedly arranged on the outer side wall of the cabinet body; the upper end of the dehumidification box is fixedly connected to the fixed frame; the air outlet of the dehumidification box is connected with an air suction pump, and the air outlet in the upper end of the air suction pumpis communicated with an air delivery pipe, and the other end of the air delivery pipe is in sealing connection with the gas discharging opening in the upper end of the side wall of the cabinet body;a semiconductor condensation piece is arranged in the dehumidification box, and a downward water outlet pipe is further communicated with the center of the bottom end of the dehumidification box. According to the electrical cabinet, the dehumidification box with the built-in semiconductor condensation piece and the air suction pump are arranged on one side of the electrical cabinet, so that the wet air in the electrical cabinet can be cyclically replaced into relatively-dried air.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet with a dehumidification mechanism. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel sheets, cold-rolled steel sheets are softer and more suitable for the production of electrical 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. A variety of electrical accessories are usually installed in the electrical cabinet, so the requirements for circuit safety are relatively high, especially if the electrical cabinet is in a re...

AI Technical Summary

Problems solved by technology

A variety of electrical accessories are usually installed in the electrical cabinet, so the requirements for circuit safety are relatively high, especially if the electrical cabinet is in a relatively humid environment for a long time, it will not only corrode the electrical components, but also easily cause circuit short circuit or other accidents. Some electrical cabinets just use some desiccant or use fans or heating elements to dehumidify, which often cannot fundamentally solve the problem of humidity
