Dehumidifying switchgear capable of automatic air intake and discharge

Abstract

The invention relates to a cabinet for power supply or distribution, and especially to a dehumidifying switchgear capable of automatic air intake and discharge. The switchgear comprises a cabinet, the cabinet is provided with a cabinet door, a sidewall of the cabinet door includes an inner wall and an outer wall, an enclosed cavity is formed between the inner wall and the outer wall, a heating pipe is arranged in the enclosed cavity and comprises a pipe body, the internal and external surfaces of the pipe body are coated with heating films respectively, the heating film at the external surface of the pipe body is further coated with an insulated thermal-conduction layer, two sidewalls, opposite to each other, of the cabinet are provided with ventilating fans respectively, the cabinet is internally provided with a detection assembly, the cabinet door is provided with a touch display screen and an alarm, and the touch display screen, the alarm, the heating pipe and the detection assembly are all connected with a controller. Thus, moisture air in the cabinet can be exhausted out of the cabinet timely, flashover and discharge are avoided, and it is ensured that devices in the cabinet operate safely and reliably.

Description

technical field [0001] The invention relates to a power supply or power distribution cabinet, in particular to an automatic air intake and exhaust dehumidification switch cabinet. Background technique [0002] At present, the dehumidification of indoor equipment in the power industry mainly relies on heating to keep the equipment dry, but in order to ensure safety, it is made into a fully sealed shape, which causes the air inside the equipment to not circulate, and the humid gas cannot be discharged, and the equipment is in a harsh environment for a long time It is easy to produce phase-to-phase or phase-to-ground flashover discharge, causing accidents. Contents of the invention [0003] In order to solve the deficiencies in the above-mentioned technologies, the purpose of the present invention is to provide an automatic air intake and exhaust dehumidification switch cabinet, which can discharge the humid gas in the cabinet to the outside of the cabinet in time, avoid flas...
