Abstract

The invention discloses a dehumidification power distribution cabinet. The cabinet comprises a base and a box body mounted at the upper end of the base, a plurality of fans are fixed at the inner bottom of the box body; two ventilation grooves are symmetrically formed in the side wall of the box body; ventilation holes are formed in the inner walls of the two ventilation grooves in a penetrating mode, opening and closing push rods are fixed to the inner walls of the ends, away from the corresponding ventilation holes, of the two ventilation grooves, sealing plates are fixed to the extending ends of the two opening and closing push rods, and a humidity sensor and a temperature sensor are fixed to the inner top of the box body. The method has the advantages that the method is simple; the timing motor drives the screw rod to rotate; therefore, the sliding block moves upwards; the timing purpose is achieved; and if the internal humidity of the box body is controlled in the time period whenthe sliding block moves upwards to the top, it shows that the external humidity is not increased continuously, the internal operation of the box body is normally carried out, and if the humidity is not quickly controlled, the sealing plate seals the ventilation hole, so that external humid air is prevented from entering the box body, and the internal humidity of the box body is not increased anymore.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a dehumidification power distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system; power distribution cabinets are collectively referred to as motor control centers. ; The motor control center is used in occasions where the load is concentrated and there are many circuits; they distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] When the power distribution cabinet is used outdoors, it will be greatly affected by the external environment, especially the influence of temperature and humidity, which will lead to a redu...
