Description

Technical Field

[0001] This invention relates to the field of C-GIS electrical cabinet technology, and more specifically to a C-GIS electrical cabinet that is easy to dehumidify. Background Technology

[0002] Gas-insulated switchgear (C-GIS) is an electrical structure that encloses circuit breakers, disconnectors, grounding switches, transformers, surge arresters, etc., within a housing filled with SF6 insulating gas.

[0003] To improve heat dissipation in C-GIS electrical cabinets, methods such as adding cooling fans inside the cabinet can be used to increase airflow efficiency and promote heat dissipation. However, these methods have the following problems: the cooling fans also generate heat during operation, resulting in slow heat dissipation from the inside of the C-GIS electrical cabinet; simultaneously, some moisture exists inside the equipment during operation. Traditionally, desiccants are used for adsorption, but the desiccant is directly exposed inside the C-GIS electrical cabinet, requiring frequent opening and replacement of the desiccant to ensure drying effectiveness.

[0020] Beneficial effects

[0021] This invention circulates the airflow inside the electrical cabinet assembly using a circulation component. The size of the absorbent material covering the circulation component filters and adsorbs moisture from the passing air. After a certain time interval, a winding component is activated, moving the absorbent material a short distance so that the moisture-absorbing material is wound onto the winding component. The new position of the absorbent material is then unwound from the unwinding component and covers the ventilation section of the circulation component. Therefore, the lifespan of the dehumidification component is greatly increased, requiring the absorbent material to be replaced approximately once a year. Compared to traditional methods that require frequent cabinet openings to replace the desiccant, this significantly reduces the frequency of opening the cabinet door to replace the absorbent material.

[0022] This invention uses a circulating component to synchronously drive the blower structure to blow air, and the gas is blown out through an air-cooling component to cool the gas circulating inside the circulating component. By installing a cooling component on the outside of the electrical cabinet component and using the cooling component to air-cool the gas circulating inside the circulating component, the heat inside the electrical cabinet component can be quickly dissipated, preventing heat accumulation inside the electrical cabinet component from affecting the normal operation of the electrical appliances, and also helping to reduce safety hazards such as fire.

Figure 1-8A C-GIS electrical cabinet for easy dehumidification includes an electrical cabinet assembly 1, and a circulation assembly 2 for circulating the airflow inside the electrical cabinet assembly 1 is installed on the outside of the electrical cabinet assembly 1.

[0038] The external part of the electrical cabinet assembly 1 is equipped with a dehumidification assembly 3 for dehumidifying the gas circulating in the circulation assembly 2;

[0039] The external part of the electrical cabinet assembly 1 is equipped with a cooling assembly 4 for cooling the gas circulating in the circulation assembly 2;

[0040] The circulation component 2 is connected to and communicates with the dehumidification component 3, and the circulation component 2 is connected to the cooling component 4;

[0041] The dehumidification component 3 includes a winding component, an unwinding component, and a water-absorbing material 38; the two ends of the water-absorbing material 38 are respectively wound around the winding component and the unwinding component, and the water-absorbing material 38 passes laterally through the circulation component 2 and can completely cover the ventilation section of the circulation component 2.

[0042] The airflow inside the electrical cabinet assembly 1 is circulated by the circulation component 2. The size of the water-absorbing material 38 covering the circulation component 2 filters the air passing through the circulation component 2 and absorbs moisture. After a certain period of time, the winding component can be activated to move the water-absorbing material 38 a certain distance, so that the water-absorbing material 38 that has absorbed moisture is wound onto the winding component. The new position of the water-absorbing material 38 is unwound from the unwinding component and covers the ventilation section of the circulation component 2. Therefore, the service life of the dehumidification component 3 can be greatly increased. The water-absorbing material 38 can be replaced about once a year. Compared with the traditional method of frequently opening the cabinet to replace the desiccant, the frequency of opening the cabinet door to replace the water-absorbing material 38 is greatly reduced.

[0044] The air is blown out by synchronously driving the blower structure through the circulation component 2. The gas is blown out through the air-cooling component to cool down the gas circulating in the circulation component 2.

[0045] By installing a cooling component 4 on the outside of the electrical cabinet assembly 1 and using the cooling component 4 to cool the circulating gas in the circulation assembly 2, the heat inside the electrical cabinet assembly 1 can be quickly dissipated, preventing heat accumulation inside the electrical cabinet assembly 1 from affecting the normal operation of the electrical appliances, and also helping to reduce safety hazards such as fire.

[0057] Based on Example 2, please refer to the appendix of the instruction manual. Figure 1-8 The winding assembly includes a winding motor 34, a winding shaft 35, and a second mounting cylinder 33.
