Description

An intelligent dehumidification online monitoring system for electrical cabinets in a transmission power system

technical field

The utility model belongs to the technical field of electric cabinet monitoring, in particular to an intelligent dehumidification online monitoring system for electric cabinets in a power transmission power system.

Background technique

In the actual operating environment of the substation, due to the compact internal space of high-voltage switch cabinets, terminal boxes and other cabinets, in high-temperature and high-humidity climates, the cabinets are prone to moisture and condensation, which greatly reduces the insulation level of the equipment and seriously Threatening the safe operation of equipment, the current traditional anti-condensation methods include manual control of heater switching, forced long-term power-on heating, automatic dehumidification controller, etc. These methods are either low in automation, poor in operability, or increase power loss and waste energy. Or due to the limitation of the principle of the sensor itself, the prevention and control effect cannot be achieved, and the reliability of the device operation cannot be guaranteed.

At present, the market generally adopts automatic heating or air-conditioning condensation to carry out cabinet or electric room dehumidifiers, which has the following disadvantages:

1. Automatic heating and dehumidification mainly uses the heating plate to heat the air in the cabinet, and then uses the fan to circulate the hot air in the cabinet. This method generally has a large power, and the moisture in the air evaporates and dries in a short time in the cabinet. When the temperature drops, it will condense into condensation and attach to the surface of the electrical components in the cabinet;

2. Air conditioner dehumidification mainly achieves the effect of dehumidification through compressed air, but it is large in size and is not suitable for installation in a small electrical cabinet. If it is installed outside the cabinet, the dehumidification effect often does not meet the operating requirements;

3. In addition, the existing device does not realize the remote transmission of the relevant data after dehumidification, and uploads it to the online monitoring and management background of the power grid, and does not realize remoteization and automation.
