Abstract

The invention discloses a ventilation and dehumidification type switch cabinet, and relates to the technical field of electric power transmission and distribution switching equipment. The ventilation and dehumidification type switch cabinet comprises a switch cabinet 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), wherein the upper part and the lower part of the switch cabinet body are provided with the fans respectively, the temperature sensor and the humidity sensor are installed on a rear plate inside the switch cabinet, and the heating device is installed at the left side inside the switch cabinet. The ventilation and dehumidification type switch cabinet has the characteristics of simple principle, convenient manufacturing, ability of effectively controlling the temperature and the 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...
