Dehumidification device

Abstract

The invention provides a dehumidification device, and relates to the technical field of electrical equipment. The dehumidification device comprises a drying and dehumidifying mechanism, a monitoring system, a circulating air inlet part, a first outlet end, a second outlet end and a regulating valve, wherein the air enters from the circulating air inlet part, after the moisture is absorbed by the drying and dehumidifying mechanism, the air is changed into dry air, the dry gas coming out of the drying and dehumidifying mechanism is controlled by the regulating valve and is supplied to power equipment or an indoor room, and the moisture of the power equipment or the indoor air is absorbed and becomes dry; the operation of an air source and an air distribution system is monitored through the monitoring system, and a condensation point temperature and a given control value can be calculated according to temperature and humidity acquisition data of the power equipment, so that a purpose of adjusting the temperature and the humidity in the power equipment is achieved, and the temperature and humidity are far away from a condensation point; a defect that the moisture prevention and the condensation prevention cannot be completely achieved in the prior art and the technical problem of low efficiency are alleviated; and the technical effects of fast dehumidification, high efficiency, great dehumidification capability and high safety are achieved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a dehumidification device. Background technique [0002] 12kV high-voltage switchgear is a kind of power equipment widely used in urban power supply and distribution systems. Changes in the temperature and humidity of its internal environment, as well as the completeness of airtightness, will affect its normal operation. When the switchgear is overhauled, it will inevitably cause external humid air to enter the inside of the cabinet, which will easily cause damp and dew inside the switchgear. If the switchgear is in such an environment for a long time state, the inside of the cabinet is prone to various vicious short-circuit faults, including single-phase short-circuit, two-phase short-circuit, and even three-phase short-circuit. In addition, long-term moisture condensation will lead to the gradual reduction of the insulation performance inside the cabinet, resulting ...
