Description

Technical Field

[0001] The utility model relates to the field of high-voltage cabinets, and more specifically, to a high-voltage cabinet with an automatic dehumidification function. Background Art

[0002] High-voltage cabinets refer to those used for switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems. High-voltage cabinets are divided into several categories, including high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switch cabinets. High-voltage switch cabinets are very susceptible to corrosion from steam, water vapor, etc., which can cause short circuits in the internal circuits of the high-voltage switch cabinets, so improvements are needed.

[0003] Although the existing high-voltage cabinets are all equipped with a moisture adsorption net structure at the air inlet of the cabinet body to absorb moisture from the outside air, such a structure still has the following disadvantages during use:

[0004] 1. Although the moisture adsorption net can have a certain moisture adsorption effect on the air passing through, it is easy to become damp over time, which reduces the moisture adsorption performance;

[0005] 2. Although some moisture can be removed from the outside air after being adsorbed by the moisture adsorption net, some moisture is still difficult to be removed and enters the cabinet. When the temperature inside the cabinet is low, the moisture will re-condense into water droplets inside the cabinet, making the dehumidification effect poor;

[0006] Therefore, we proposed a high-voltage cabinet with automatic dehumidification function to solve the above problems. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-voltage cabinet with an automatic dehumidification function. Through a dehumidifier installed at the mesh port, the outside air can contact with the filled granular desiccant after entering the dehumidification chamber, and an agitator is installed inside the dehumidification chamber to continuously stir the granular desiccant, thereby promoting the uniformity of the contact between the outside air and the granular desiccant and improving the dehumidification effect of the air passing through; and a U-shaped heating tube is installed inside the heating chamber, which can increase the temperature of the air when it passes through the U-shaped heating tube, thereby increasing the temperature inside the high-voltage cabinet body, avoiding the re-condensation into water droplets inside the high-voltage cabinet body due to the low temperature inside the high-voltage cabinet body and the small amount of water vapor still contained in the air passing through, thereby reducing the probability of the high-voltage cabinet body getting damp; and by controlling the forward and reverse rotation of the driving shaft of the driving motor and the dual-axis motor, the air inside the high-voltage cabinet body is reversely drawn out, and the air temperature is increased when passing through the U-shaped heating tube, thereby achieving the effect of drying the granular desiccant.

[0034] A reducer 13 is fixedly installed on one side of the outer wall of the shell 4, and the output shaft of the reducer 13 is connected to the corresponding end of the shaft of the agitator 12 through a coupling. An opening 1 is opened at the top of the dehumidification chamber 402, and a cover plate 14 is fixedly installed on the top of the opening 1.

A support arm 16 is fixedly welded on one side of the outer wall of the shell 4, and a steering gear 2 is fixedly installed at the bottom of the support arm 16. 17, the output shaft of the steering gear 15 is connected to the input shaft of the steering gear 2 17 through a connecting shaft 18, the output shaft of the steering gear 2 17 is connected to the input shaft of the reducer 13 through a connecting shaft 2 19, an opening 2 is opened on the top of the heating chamber 401, a group of U-shaped heating tubes 21 are fixedly installed on the top of the opening 2 through a cover plate 20, a plurality of temperature sensors are fixedly installed inside the high-voltage cabinet body 1, and the outer walls of the partition 1 5, the partition 2 6 and the protective cover 7 are all in a metal mesh structure.

[0035] The working principle of the dehumidifier of this high-voltage cabinet with automatic dehumidification function is:

[0036] First, the dehumidifiers 3 located on the side panels 2 on both sides of the high-voltage cabinet body 1 are started, and the drive motor 8 and the drive shaft of the dual-axis motor 9 inside one of the dehumidifiers 3 are in a forward rotation state, driving the corresponding fan blades 10 to rotate forward, so as to meet the condition of sucking air from the outside to the inside of the high-voltage cabinet body 1, and the drive motor 8 and the drive shaft of the dual-axis motor 9 inside the other dehumidifier 3 are in a reverse rotation state, driving the corresponding fan blades 10 to rotate reversely, so as to meet the condition of exhausting air from the inside of the high-voltage cabinet body 1 to the outside;

[0037] That is, when the driving motor 8 and the dual-axis motor 9 in one of the dehumidifiers 3 are started, the corresponding fan blades 10 are driven to rotate forward. At this time, the outside air enters the position of the partition 5 of the dehumidifier 3 through the mesh port 201 on the side panel 2 and passes through, and then is heated by a group of U-shaped heating tubes 21 and enters the dehumidification chamber 402 to contact with the granular desiccant for dehumidification, and then the air after adsorption and dehumidification passes through the protective cover 7 and smoothly enters the high-voltage cabinet body 1;

[0038] The air entering the high-voltage cabinet body 1 is driven by the fan blades 10 of another dehumidifier 3 to be discharged outward. During this process, the air inside the high-voltage cabinet body 1 first enters the protective cover 7, and then passes through the dehumidification chamber 402 and the heating chamber 401 and is discharged from the mesh port 201 on the side panel 2, thereby completing the entire air flow process inside the high-voltage cabinet body 1. Several temperature sensors fixedly installed inside the high-voltage cabinet body 1 are used to monitor the temperature inside the cabinet body in real time to prevent the temperature from being too high.
