AI Technical Summary

Problems solved by technology

[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 short-circuited. There will be refusal or tampering of substation equipment, etc.
The potential safety hazards caused by these problems have greatly affected the safe operation of substation equipment, resulting in frequent occurrence of power grid accidents.

Embodiment

[0029] figure 1 It is a schematic structural diagram of a dehumidification system provided in an embodiment of the present application.

[0030] Such as figure 1 As shown, the system includes:

[0031] Dehumidification device 1;

[0032] heating device 2;

[0033] A temperature and humidity sensor 3 for detecting the temperature and humidity value of the gas in the control box;

[0034] It is connected with the dehumidification device 1, the heating device 2 and the temperature and humidity sensor 3, and is used to control the dehumidification device and / or the controller 4 of the heating device to adjust the humidity of the gas in the control box by using the temperature and humidity value detected by the temperature and humidity sensor;

[0035] A power supply 5 connected to the controller.

[0036] In the embodiment of this application, the controller judges whether the humidity value in the temperature and humidity value detected by the temperature and humidity sensor...

Abstract

The invention provides a dehumidifying system. A humiture sensor detects the humiture value of the gases in a control cabinet, a controller controls a dehumidifying device and / or a heating device to adjust the gas humidity in the control cabinet by means of the humiture value detected by the humiture sensor so as to control the drying degree in the control cabinet of a transformer, so that the problems that the safe running of the transformer is influenced and the power grid accidents frequently occur because the components in the control cabinet are easy to damp can be prevented.

Description

technical field [0001] The present invention relates to the technical field of electric equipment, and more specifically, relates to a dehumidification 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...
