Abstract

The invention discloses a 35kV switch cabinet dehumidifying device based on adsorption rotary-wheel dehumidification. The 35kV switch cabinet dehumidifying device comprises a dehumidifying device shell, wherein a display panel is arranged on the upper surface of the dehumidifying device shell, a gas inlet end is arranged at one end of the dehumidifying device shell, a gas outlet end is arranged at the other side of the dehumidifying device shell, the gas inlet end and the gas outlet end are respectively communicated with a 35kV switch cabinet by means of pipelines to form a circulating loop, an adsorption rotary wheel is arranged in the dehumidifying device shell, and divided into a moisture adsorbing region and a regenerating region, the moisture adsorbing region and the regenerating region are alternatively converted under the rotation of the adsorbing rotary wheel, one side of the moisture adsorbing region is positioned at the gas inlet end, a processing fan is arranged at the other side of the moisture adsorbing region, an air outlet end of the processing fan is communicated with the gas outlet end, a regenerating fan is arranged at one side of the regenerating region, and a heater is arranged at the other side of the regenerating region. According to the 35kV switch cabinet dehumidifying device, self circulation and dehumidification of air in a switch cabinet are realized, the humidity of air in the switch cabinet is reduced, explosion accidents are effectively prevented, and good application prospect is obtained.

Description

technical field [0001] The invention specifically relates to a 35kV switch cabinet dehumidification device based on adsorption runner dehumidification, which belongs to the technical field of electrical protection equipment. Background technique [0002] In recent years, there have been 35kV switchgear explosion accidents in the middle frequency of the power grid. In 2011 alone, there were 220kV Nongge Substation 35kV Section I bus 200 switch interval explosions and 220kV Shugang 35kV bus tie 310 circuit breaker and Ganghe line 366 circuit breaker interval in the Yangzhou work area. A discharge explosion accident occurred, causing serious losses. After on-site investigation and analysis of the cause of the accident, it was found that the humidity in the switchgear was high (there was condensation phenomenon), which led to the decrease of the insulation strength of the switchgear and the discharge was the main cause of the two accidents, and the original heater of the switchg...
