Anti-condensation electrical cabinet

Abstract

The invention discloses an anti-condensation electrical cabinet. The cabinet comprises a cabinet body; the top end of the cabinet body is provided with a cooling fan; an electric heating assembly is fixedly installed in the middle of the side wall of the cabinet body; the electrode end of the electric heating assembly is electrically connected with an external power supply; an inner temperature sensor is also fixedly mounted in the cabinet body; an outer temperature sensor is arranged on the outer side of the cabinet body; a first temperature controller is further installed in the cabinet body; the inner temperature sensor and the outer temperature sensor are both in signal connection with the input end of the first temperature controller; and the output end of the first temperature controller is in signal connection with the cooling fan and the electric heating assembly. An air conditioner adjusting device is further installed at the top end of the cabinet body, a second temperature controller is further installed in the cabinet body, the input end of the second temperature controller is in signal connection with the inner temperature sensor, and the output end of the second temperature controller is in signal connection with the air conditioner adjusting device, the electric heating assembly and the cooling fan. The anti-condensation electrical cabinet solves the problem thatmoisture condensation of the electrical cabinet cannot be fundamentally eradicated through a traditional dehumidification mode.

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
