Abstract

The invention provides a switch cabinet operating environment improving system and method. The system comprises a switch cabinet, an axial flow fan, an industrial constant temperature dehumidifier, and temperature and humidity sensors, wherein the switch cabinet is arranged in a closed switch room; the axial flow fan is mounted on a pressure relief plate on the top of the switch cabinet; the axialflow fan is in signal connection with a controller in the switch room; the switch room is also internally provided with the industrial constant temperature dehumidifier and the temperature and humidity sensor for detecting the switch cabinet; the temperature and humidity sensor that detects air temperature and humidity is arranged outside the switch room; and the industrial dehumidifier and the temperature and humidity sensors inside and outside the switch room are in signal connection with the control system. The air in the switch cabinet is ensured to be dry, and insulation flashover and insulation damage of the equipment in the switch cabinet are reduced.

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...
