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 provides a ventilation and dehumidification type switch cabinet, and relates to the technical field of power transmission and distribution switch equipment. The ventilation dehumidification type switch cabinet comprises a switch cabinet main body (a), fans (b), a temperature sensor (c), a humidity sensor (d), an HD-ZWSK-SX-series intelligent digital display temperature and humidity controller and a heater (e); the fans are mounted at the upper part and the lower part of the switch cabinet main body; the temperature sensor and the humidity sensor are mounted on a back panel in the switch cabinet; the heater is mounted on the left side in the switch cabinet. The ventilation and dehumidification type switch cabinet has the characteristics of being simple in principle, convenient to manufacture, capable of effectively controlling temperature and humidity inside the switch cabinet, and the like.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution switchgear, in particular to a ventilation and dehumidification switchgear. 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 influence betw...
