Problems solved by technology

The mutual influence between the air circuit breaker heating, the rated continuous current of the air circuit breaker, and the external ambient temperature is often ignored. According to the fact that when the switchgear is working with load, the current passing through it will be very large, which will increase the temperature of the equipment and cause the inside of the cabinet to The temperature rise will further affect other electrical components, especially in summer, which will seriously affect their service life, so the impact of heat generation cannot be ignored

Abstract

A ventilation and dehumidification type switch cabinet relates to the technical field of electric power transmission and distribution switch equipment. The ventilation and dehumidification type switch cabinet includes a switch cabinet main body (a), fans (b), a temperature sensor (c), a humidity sensor (d), an intelligent digital display humiture controller of the HD-ZWSK-SX series and a heater (e). The fans are respectively installed in the upper surface and the lower surface of the switch cabinet main body. The temperature sensor and the humidity sensor are installed on a rear board inside the switch cabinet. The heating device is installed in the left side of the switch cabinet. The ventilation and dehumidification type switch cabinet of the invention has characteristics that the principle is simple; the making is convenient; humiture in the switch cabinet can be effectively controlled, etc.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution switchgear, in particular to a ventilation and dehumidification switch cabinet. Background technique [0002] With the development of power transmission and distribution, in places with poor environmental conditions such as plateaus, especially in outdoor cabinets, the switchgear generates heat during use, and areas with high humidity all year round are the reasons for the aging of switchgear and the decrease in the current level it withstands. At present, the technology of similar switch cabinets generally adopts natural air heat dissipation and high humidity, which is easy to generate condensation on the electrically conductive parts, so that the safety cannot be guaranteed. [0003] During the use of electrical equipment, the service life decreases exponentially with the increase of temperature. There are many factors that affect its continuous running current. The...
