An anti-condensation electrical cabinet

Abstract

The invention discloses an anti-condensation electrical cabinet, which comprises a cabinet body, a cooling fan is installed on the top of the cabinet body, an electric heating assembly is fixedly installed in the middle of the side wall of the cabinet body, and the electrode end of the electric heating assembly is electrically connected with an external power supply. An internal temperature sensor is also fixedly installed, an external temperature sensor is arranged on the outside of the cabinet, and a first temperature controller is also installed in the cabinet, and both the internal temperature sensor and the external temperature sensor are connected to the input signal of the first temperature controller. The output end of a temperature controller is respectively connected to the cooling fan and the electric heating component; an air conditioning adjustment device is installed on the top of the cabinet, and a second temperature controller is installed in the cabinet, and the input end of the second temperature controller is connected to the inner The signal of the temperature sensor is connected, and the output terminal of the second temperature controller is connected with the signal of the air conditioning adjustment device, the electric heating assembly and the cooling fan. The invention solves the problem that the traditional dehumidification method cannot fundamentally eliminate dew condensation in the electrical cabinet.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an anti-condensation electrical cabinet. 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 condensation problem is serious, it is easy t...

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 condensation problem is serious, it is easy to cause circuit short circuit or other accidents, while the existing electrical cabinets only use some desiccant or use fans Dehumidification, and the problem of condensation is often caused by the large temperature difference between the inside and outside of the electrical cabinet, so the traditional dehumidification method often cannot fundamentally eliminate the problem of condensation in the electrical cabinet
