System and method for improving operating environment of switchgear

Abstract

The invention provides a system and method for improving the operating environment of a switchgear, including a switchgear, an axial flow fan, an industrial constant temperature dehumidifier, and a temperature and humidity sensor. Axial flow fan, the axial flow fan is connected with the controller signal in the switch room, the switch room is also equipped with an industrial constant temperature dehumidifier and a temperature and humidity sensor to detect the temperature and humidity in the switch room, and a temperature and humidity sensor to detect air temperature and humidity is also arranged outside the switch room, industrial dehumidification The signals of temperature and humidity sensors in the machine, switch room and outside are connected to the control system. The invention is used to ensure that the air in the switch cabinet is dry, and reduce the insulation flashover and insulation damage of the equipment in the switch cabinet.

Description

technical field [0001] The invention belongs to the technical field of electrical insulation protection, and in particular relates to an environment optimization system and method for a switch cabinet. Background technique [0002] Insulation breakdown (insulation breakdown): It refers to the complete loss of insulation ability when the insulator is damp or subjected to excessive voltage. [0003] Insulation flashover: refers to the discharge phenomenon that occurs on the surface of the insulation structure or in the air in contact with the electrode under the action of an electric field before the breakdown of the insulation structure occurs. [0004] High-voltage switchgear is the most widely used and most numerous switchgear. Because there are different degrees of problems in design, manufacture, installation and operation and maintenance, the accident rate is relatively high. Among the switchgear accidents of many natures, insulation accidents mostly occur at voltage l...

Problems solved by technology

[0008] 1. Install a dehumidifier or air conditioner in the switch room: installing air conditioners, exhaust fans or mobile cabinet dehumidifiers in the switch room can only improve the ambient air humidity conditions in the switch room, and have little effect on the temperature and humidity in the cabinet

[0009] 2. The switchgear is sealed and sealed with glue: generally, a sealing strip is installed on the door of the switchgear to seal the bottom of the cable room of the switchgear and strengthen the sealing of the switchgear, but the humidity in the air inside the cabinet will also affect the The insulation of the equipment is affected, and there is no temperature regulation effect

[0010] 3. Increase the ventilation holes on the top of the cabinet: by increasing the ventilation holes, the sufficient circulation of the air inside and outside the switchgear cannot be satisfied, so the effect of increasing the ventilation holes is limited
