Description

Technical Field

[0001] This application relates to the field of transformer cooling technology, and more specifically, to a transformer winding directional spray cooling device and its usage method. Background Technology

[0002] Transformers are the core power supply equipment in substations. During operation, the losses in the windings and core generate a large amount of heat, which must be dissipated in a timely manner to prevent overheating and insulation damage. Currently, most distribution transformers and power transformers use oil-immersed self-cooling for heat dissipation, relying on the natural thermal circulation of the oil to carry the heat to the radiator and using air convection to remove the heat.

[0003] However, with the continuous growth of electricity load, especially during the high-temperature period in summer, transformers heat up rapidly, and the original heat dissipation methods are no longer sufficient. Existing auxiliary heat dissipation methods mainly include the use of fans or water spray cooling, but they have the following shortcomings: First, most spray devices are manually or semi-automatically controlled, making it impossible to accurately start and stop them according to the temperature; second, the spray water is discharged directly, resulting in serious waste of water resources; and third, impurities in the spray water easily clog the nozzles and filter components, requiring frequent maintenance.

[0022] The technical effects and advantages of this application are as follows:

[0023] Compared with existing technologies, this transformer winding directional spray cooling device and its usage method utilizes a spray mechanism where a water pump draws cooling water from a storage tank via a water pipe. The start / stop and water volume of the spray are precisely controlled by a water supply valve. Multiple sets of spray pipes spaced along the width of the protective frame and nozzles spaced along the length of the spray pipes ensure that the nozzles spray directly onto the transformer windings and heat sinks, achieving directional and precise spraying. This effectively improves the utilization efficiency of the cooling water and solves the problems of traditional spray devices requiring manual or semi-automatic control and lacking precise start / stop. Simultaneously, a blower mechanism generates a high-speed airflow, which is delivered through an air supply pipe and valve to the connecting pipe and spray pipes, and then blown out by the nozzles. This provides direct air cooling and also dries the surface water of the transformer after spraying, preventing residual moisture from corroding the equipment or reducing its insulation performance.

[0024] Compared with existing technologies, this transformer winding directional spray cooling device and its usage method guides the sprayed water to the filter plate in the limiting groove through an inclined trough. After filtering and removing impurities, the water falls into the water storage tank for recycling, significantly saving water resources and effectively solving the waste problem caused by direct discharge of spray water. At the same time, the drive motor of the cleaning mechanism drives the threaded rod to rotate, causing the slider to slide back and forth along the sliding groove, so that the brush automatically brushes the surface of the filter plate, pushing impurities into the collection box. When the collection box is full, it can be pulled out by the second handle for cleaning and reinstalled in the fixed groove. This realizes automatic cleaning of the filter plate, avoiding the trouble of frequent manual disassembly and cleaning of the filter plate, ensuring that the filter plate maintains a good filtration effect for a long time, reducing maintenance frequency and operation and maintenance costs, and ensuring long-term stable operation of the device.

The brush 1105 pushes the cleaned impurities into the collection box 1107 at one end of the filter plate 1003. When the impurities in the collection box 1107 accumulate to a certain extent, the operator uses the second handle 1108 to pull the collection box 1107 out of the fixed groove 1106, cleans the impurities inside, and then puts the collection box 1107 back into the fixed groove 1106 for continued use.

The protective net 407 is used to isolate external debris. At the same time, multiple sets of water spray pipes 5 and nozzles 6 are connected to the dual circuit of spraying and blowing through the connecting pipe 8. When the temperature of transformer 1 rises, the spray mechanism 7 is activated. The water pump 701 draws cooling water from the water storage tank 3 through the water extraction pipe 702, and sends it to the connecting pipe 8 through the water delivery pipe 703 and the water supply valve 704. Then, it is distributed to each spray pipe 5, and finally sprayed directionally onto the windings and heat sinks of transformer 1 by the nozzles 6. After the spraying is completed, the blower mechanism 9 is activated. The high-speed airflow generated by the blower 902 is sent into the connecting pipe 8 and the spray pipes 5 through the air delivery pipe 903 and the air supply valve 904, and blown out by the nozzles 6, so as to dry the surface water after the spraying is completed, or directly cool the transformer 1 with air. The water after spraying flows along the surface of transformer 1 and the fixing frame 2 to the inclined groove 1001, and is guided by the inclined groove 1001 to the filter plate in the limiting groove 1002. 1003, after filtering and removing impurities, falls into the water storage tank 3 for recycling; after long-term use, the drive motor 1102 of the cleaning mechanism 11 can be started to drive the threaded rod 1103 to drive the slider 1104 to slide back and forth along the slide groove 1101, so that the brush 1105 brushes the surface of the filter plate 1003 and pushes the impurities into the collection box 1107. After the collection box 1107 is full, it is pulled out for cleaning through the second handle 1108 and reinstalled into the fixing groove 1106, thereby ensuring the long-term stable operation of the filter plate 1003, thus realizing the integrated functions of efficient spray cooling, air cooling assistance, circulating filtration and automatic cleaning of the transformer. The above is the working principle of this transformer winding directional spray cooling device and its usage method.
