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

The invention discloses a switch cabinet with functions of ventilation and dehumidification, and relates to the technical field of power transmission and distribution switchgear. The cabinet comprises a switch cabinet main body (a), fans (b), a temperature sensor (c), a humidity sensor (d), an intelligent digital display temperature and humidity controller of an HD-ZWSK-SX series, and a heater (e). The upper and lower parts of the switch cabinet main body (a) are respectively provided with the fans (b). The temperature sensor (c) and the humidity sensor (d) are disposed on a rear plate in the switch cabinet, and a heating device is disposed at the left side of the interior of the switch cabinet. The cabinet is simple in principles, is convenient to manufacture, and can effectively control the internal temperature and humidity.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution switchgear, in particular to a switchgear with ventilation and dehumidification functions. Background technique [0002] With the development of power transmission and distribution, places with poor environmental conditions such as plateaus, especially outdoor cabinets, switchgear body heat during use, and areas with high humidity all year round are the reasons for the aging of switchgear and the decline in the current level it withstands. At present, the technology of similar switch cabinets generally adopts natural air heat dissipation, and the high humidity 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 affecting its continuous operating current. The mutual...
