Embodiment 1

[0034] figure 1 It is a schematic structural diagram of a dehumidification system provided in Embodiment 1 of the present application.

[0035] Such as figure 1 As shown, the system includes:

[0036] Dehumidification device 1;

[0037] A humidity sensor 2 for detecting the humidity value of the gas in the control box;

[0038] One end is connected to the humidity sensor 2, and the other end is connected to the dehumidification device 1, which is used to control the first controller 3 of the dehumidification device to adjust the humidity of the gas in the control box by using the humidity value detected by the humidity sensor;

[0039] A power supply 4 connected to the first controller 3 .

[0040] Preferably, the first controller uses the humidity value detected by the humidity sensor to control the dehumidification device to adjust the humidity of the gas in the control box: judge whether the obtained humidity value detected by the humidity sensor is higher than the pres...

Embodiment 2

[0056] figure 2 It is a flowchart of a dehumidification method provided in Example 2 of the present application.

[0057] Such as figure 2 As shown, the method includes:

[0058] S101. The first controller acquires the humidity value of the gas in the control box detected by the humidity sensor.

[0059] Specifically, the dehumidification method provided in the embodiment of the present application is provided on the basis of the dehumidification system provided in the first embodiment above.

[0060] S102. Using the humidity value to control the dehumidification device to adjust the humidity of the gas in the control box.

[0061]Specifically, after the first controller obtains the humidity value of the gas in the control box detected by the humidity sensor, it will use the humidity value to control the dehumidification device to adjust the humidity of the gas in the control box.

[0062] Specifically, the dehumidification device includes: a ventilation module connected...

Abstract

The application provides a dehumidifying method and system. The dehumidifying method and system is characterized in that a humidity sensor detects the humidity value of a gas in a control box, a first controller utilizes the humidity value detected by the humidity sensor to control a dehumidifying device to control the humidity of the gas in the control box, so that the drying degree control in the control box of the power transformation equipment is realized, and the problem that the elements in the control box are affected with damp easily to influence the safe operation of the power transformation equipment and cause the frequent power grid accidents is avoided.

Description

technical field [0001] The present invention relates to the technical field of power equipment, and more specifically, to a dehumidification method and system. Background technique [0002] Various electronic components are installed in the control boxes of power transformation equipment such as high-voltage cabinets, indoor / outdoor switches, knife control boxes, and power boxes to realize various control and execution functions. In order to ensure the reliability of the use and service life of the substation equipment, the control box of this type of substation equipment has strict requirements on the dryness of the working environment. [0003] The components in the control box of the substation equipment are prone to moisture when the weather changes, which will cause the rotating part of the substation equipment to fail when performing work, the insulation resistance will drop, resulting in electrical breakdown, and the secondary terminals may be poorly connected or shor...
