Problems solved by technology

[0003] When the switchgear is in use, it is necessary to detect the internal and external temperature and humidity to prevent the temperature and humidity from exceeding the design standard of the switchgear, resulting in damage to the switchgear. In the prior art, when the temperature and humidity exceed the standard, it is generally placed in the electrical cabinet A certain amount of desiccant is used to absorb water vapor in the air. This method can have a certain dehumidification effect, but the effect is very small. For the case of high indoor water vapor concentration, the desiccant will lose its dryness due to absorbing more water vapor after a long time effect, can not be well utilized, inconvenient to use

Embodiment 1

[0026] Such as Figure 1-2 As shown, a moisture-proof method for high and low voltage switchgear proposed by the present invention includes

[0027] S1. Set the maximum value of relative temperature and humidity according to the provisions of GB / T110;

[0028] S2. Detect the humidity in the cabinet 2 through the temperature and humidity detector in the cabinet 2; if the detection result is lower than the preset maximum value, no operation is performed; if the detection result is higher than the preset maximum value, start pumping wet machine;

[0029] S3. The dehumidifier 3 converts the humid air outside into dry cold air;

[0030] S4, conveying the cold air into the cabinet body 2 through the conveying device 4;

[0031] S5, the humid air in the cabinet 2 is discharged from the cabinet 2 through the ventilation device 5;

[0032] S6, the temperature and humidity detector in the cabinet 2 continuously detects the humidity in the cabinet 2;

[0033] S7. The temperature and...

Embodiment 2

[0037] Such as Figure 1-2 As shown, the present invention proposes a moisture-proof method for high and low voltage switch cabinets. Compared with Embodiment 1, this embodiment also proposes a high and low voltage switch cabinet, including a protective device 1, a cabinet body 2, a dehumidifier 3, Conveying device 4, ventilating device 5, display 6 and ventilation equipment 7; cabinet body 2 and dehumidifier 3 are arranged in protective device 1; output end of dehumidifier 3 is connected with conveying device 4, and conveying device 4 is connected with cabinet The body 2 is connected; the ventilation device 5 is arranged at the lower end of the cabinet body 2, and the ventilation device 5 is located on the side away from the conveying device 4; the display 6 is arranged on the cabinet body 2; the ventilation device 7 is arranged on the protective device 1. The protection device 1 is provided with a plurality of ventilation slots; the ventilation slots allow the air to circula...

Abstract

The invention relates to a moisture-proof method for a high-low voltage switch cabinet, and belongs to the technical field of switch cabinets. The method comprises the following steps: S1, setting the maximum value of relative temperature and humidity according to the regulation of GB / T110; s2, detecting the humidity in the cabinet body through a temperature and humidity detector in the cabinet body; if the detection result is lower than the preset maximum value, operation is not carried out; if the detection result is higher than the preset maximum value, the dehumidifier is started; s3, the dehumidifier converts external humid air into dry cold air; s4, cold air is conveyed into the cabinet body through a conveying device; s5, discharging humid air in the cabinet body out of the cabinet body through an air interchanger; and S7, a temperature and humidity detector outside the cabinet body detects the environment temperature and humidity outside the cabinet body, and if a detection result is higher than a preset maximum value, a ventilation device is started to ventilate the environment outside the cabinet body, so that the temperature difference between the interior of the cabinet body and the exterior of the cabinet body is reduced, and moisture condensation is prevented. The interior and exterior of the switch cabinet can be well cooled and dehumidified to achieve a moisture-proof effect.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a moisture-proof method for high and low voltage switch cabinets. Background technique [0002] The switch cabinet is a kind of electrical equipment. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operat...
