[0015] According to the above technical solution, a decentralized transformer cooling method and a method for using a decentralized transformer cooling system include the following steps: S1: Equipment assembly: The cooling treatment box is fixed and installed by combining screws and internal thread fixing blocks, the integrated support rod and the treatment transformer box are fixed and installed by fixing bolts, the fitting treatment plate and the cooling operation box are assembled by combining screws and fixing nuts, and the load-bearing mounting frame and the cooling operation box are assembled by fixing nuts and bidirectional screws to realize equipment installation and processing; S2: Internal cooling: The heat is transferred outwards through the internal air circulation rack, the dispersed heat exchange rack and the processing transformer box, and the transformer oil filled inside is used to absorb heat and cool the transformer core. The circulating pipe rack and the circulating oil pump drive the internal oil flow to achieve internal cooling and temperature balancing. S3: Dual cooling: The transformer oil is sprayed to the transformer core through the internal pump and the internal and external inlet and outlet pipes to the hollow support rod, the liquid inlet pipe rack and the flushing fixed bucket. The internal and external oil exchange cooling treatment is realized through the external liquid inlet cooling, the external discharge buffer barrel, the external discharge operation pipe, the internal buffer barrel and the external discharge linkage pipe. The oil circulation at the position of the external cooling circulation rack is driven by the dual treatment pipe rack and the internal pump to realize the internal and external circulation cooling and temperature balancing treatment; S4: Circulation and mixing: The oil is thermally expanded and discharged externally through the external discharge buffer barrel, external discharge operation pipe, internal storage buffer barrel and external discharge linkage pipe to connect the transformer box and transformer integration box. The transformer integration box and storage buffer box are connected in series through the reflux treatment pipe and the upper row treatment pipe to achieve internal environmental buffering treatment and internal and external oil circulation exchange treatment, thereby improving the cooling speed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. An internal and external cooling circulation component is provided, which contacts the oil in the transformer integration box through the internal air circulation rack and the dispersed heat exchange rack. The circulating pipe rack and the circulating oil pump drive the oil in the processing transformer box to flow in both directions, so that the oil in the processing transformer box is exchanged internally, driving the oil flow, and cooperating with the internal pump, liquid pipe rack, flushing fixed bucket, internal and external inlet and outlet pipes and internal air circulation rack to drive the oil in the transformer integration box to be injected into the processing transformer box, and use the oil to directly cool the transformer core. Through the self-circulation of the internal oil, the oil is driven to flush the transformer core, thereby improving the cooling speed of the transformer core. The double-processing pipe rack, the internal pump and the external cooling circulation rack are used to drive the oil in the transformer integration box to circulate, realizing multi-position circulation heat dissipation, cooperating with the external discharge buffer barrel, the external discharge operation pipe, the internal storage buffer barrel and the external discharge linkage pipe to realize the internal and external oil exchange processing, thereby increasing the heat exchange area and improving the heat exchange efficiency, and adjusting the oil cooling speed according to the internal temperature, so that the transformer is always in a stable operating environment; The oil overflowed due to thermal expansion in the transformer box is discharged and stored through the external buffer barrel, external operation pipe, internal buffer barrel and external linkage pipe, and the oil is injected into the transformer integration box. The blocking fixed ring, two-way movable frame, insert sealing block and spring reset rod are used for limiting treatment to achieve internal and external isolation while collecting and treating the external spilled oil. The reflux treatment pipe and upper treatment pipe are used to overflow the hot oil in the transformer integration box into the storage buffer box. The spring reset rod, sliding sealing pad and isolation limit ring are used to achieve oil overflow and oil injection, which not only increases the heat dissipation area of ​​the transformer, but also avoids the impact of oil overflow on the operating environment. At the same time, the oil level is controlled in real time according to the temperature, and it can effectively cooperate during the oil circulation cooling, thereby ensuring the stability of the transformer operating environment and the stability of the oil level. Through the coordination of the internal self-circulation of the double-box oil and the internal and external coordinated circulation, the liquid circulation flushing cooling of the transformer core and the external multi-point air cooling treatment are coordinated to realize the internal and external heat exchange treatment, and at the same time balance the internal temperature. The external overflow equipment and the reflux equipment are used to realize oil control, which effectively solves the problem in the prior art that the heat is concentrated in the position of the transformer core due to the inability of the oil to circulate, making it impossible to even out the internal temperature, and only through external air cooling, resulting in poor heat removal efficiency. At the same time, the oil overflow and oil level control are used to increase the heat exchange area, avoid the influence of the oil on the operating environment and operating stability, thereby increasing the heat exchange area, accelerating the heat exchange speed, balancing the overall temperature, and realizing the steady operation of the transformer.

[0017] 2. A double cooling supporting assembly is provided, and the cooling treatment box and the inserted heat exchange cylinder are inserted into the top of the transformer integration box through the internal thread fixing block, so that the cooling treatment box and the subdivided heat exchange plate are fixed to the top of the transformer integration box, and the inserted heat exchange cylinder and the cooling operation box are combined with the transformer integration box by the fixing nut and the combination screw, and the load-bearing mounting frame and the cooling operation box are fixedly connected in coordination with the fixing nut and the bidirectional screw, and the embedded heat exchange plate is embedded into the load-bearing mounting frame to realize the combined positioning of the equipment, ensure the stability of the equipment connection and the convenience of installation, and realize the heat exchange treatment of the top of the transformer through the subdivided heat exchange plate, the cooling treatment box and the inserted heat exchange cylinder with the transformer integration box and the storage buffer box. The bottom of the transformer integration box is contacted and heat exchanged through the cooling operation box, the inserted heat exchange cylinder, the heat exchange contact frame, the load-bearing mounting frame and the air inlet and outlet holes. The bottom of the transformer is cooled by contact heat exchange, liquid cooling and external wind cooling cycle treatment. The top and bottom bidirectional heat dissipation and heat exchange treatment are used to increase the area and efficiency of the transformer heat exchange and improve its cooling efficiency.

[0018] In summary, by cooperating with each other, the internal and external cooling circulation components and the double cooling support components, the oil circulation treatment inside the transformer is utilized to increase the speed of heat conduction to the outside, and the multi-point contact air cooling and liquid cooling heat exchange at the external side, top and bottom are coordinated to greatly increase the cooling area of ​​the transformer, effectively improve the cooling speed, and ensure the stable operation of the transformer.

[0025] The working principle and use process of the present invention are as follows: When installing the transformer, the staff inserts the cooling treatment box 303 and the inserted heat exchange cylinder 308 into the top of the transformer integration box 1, and assembles and installs the cooling treatment box 303 and the subdivided heat exchange plate 304 to the top of the transformer integration box 1 through the internal thread fixing block 302 and the cooling treatment box 303 through the limit bolt 315, thereby fixing the cooling treatment box 303 and the subdivided heat exchange plate 304 to the top of the transformer integration box 1, embedding the inserted heat exchange cylinder 308 at the top of the cooling operation box 307 into the top of the transformer integration box 1, and fitting the treatment plate 306 and the combination screw 305 together, and fitting the treatment plate 306 and the combination screw 305 together. 06 is attached to the bottom of the transformer integration box 1, and the fixing nut 316 and the combination screw 305 are used to combine and connect the bonding processing plate 306 and the cooling operation box 307. The hole combination bar 310 at the bottom of the cooling operation box 307 is inserted into the inner side of the load-bearing mounting frame 311, and the bidirectional screw 312 is inserted into the heat exchange contact frame 309 and the inner side of the hole combination bar 310. The load-bearing mounting frame 311 and the cooling operation box 307 are fixedly connected by the fixing nut 316 and the bidirectional screw 312, and the embedded heat exchange plate 313 is embedded in the load-bearing mounting frame 311 to achieve combined positioning; The heat exchange treatment of the top of the transformer is achieved by contacting and exchanging heat with the transformer integration box 1 and the storage buffer box 223 through the subdivided heat exchange fins 304, the cooling treatment box 303 and the inserted heat exchange cylinder 308. The bottom of the transformer integration box 1 is contacted and exchanged with heat through the cooling operation box 307, the inserted heat exchange cylinder 308, the heat exchange contact frame 309, the load-bearing mounting frame 311 and the air inlet and outlet holes 314. The bottom of the transformer is cooled by contact heat exchange, liquid cooling and external wind cooling circulation. The external wiring device is connected to electricity through the wiring terminal 301. When the transformer core 205 is running, the transformer core 205 dissipates heat to the transformer oil in the transformer box 203. The transformer oil expands due to the heat. The transformer oil in the transformer box 203 expands outward to the external buffer barrel 214. The oil pushes the inserted sealing block 220 to separate from the blocking fixing ring 218 in the external operation pipe 215. The oil flows along the external operation pipe 215 into the internal buffer barrel 216. At this time, the two-way movable frame 219 The sealing block 220 is pushed and inserted into the side end of the blocking fixing ring 218 in the external discharge linkage pipe 217. At this time, the oil will not be discharged from the internal buffer barrel 216 along the external discharge linkage pipe 217. When the expansion of the processing transformer box 203 is completed, the spring reset rod 227 drives the two-way moving frame 219 to move and reset along the internal buffer barrel 216, and the oil in the internal buffer barrel 216 is connected with the oil in the transformer integration box 1 through the external discharge linkage pipe 217, so as to realize the external discharge cooling treatment of the oil, and the processing transformer box 203 is cooled. 03 is buffered, and the oil in the inner air circulation rack 209 and the processing transformer box 203 is heat-conducted to the inner air circulation rack 209 and the dispersed heat exchange rack 212. The transformer oil in the transformer integration box 1 absorbs the heat on the surface of the inner air circulation rack 209 and the dispersed heat exchange rack 212 to realize heat conduction outward. The circulating oil pump 211 and the circulating pipe rack 210 drive the oil in the inner air circulation rack 209 to circulate, realizing the internal liquid flow. At this time, the internal liquid self-circulation flow heat exchange , improve the efficiency of internal heat exchange, when the internal temperature decreases, the liquid level decreases, when the liquid level drops to the limited liquid level position of the injection fixed pipe 234, the spring reset rod 227 drives the sliding seal 228 to move along the isolation limit ring 236, opens the injection bent pipe 221, and allows the oil in the transformer integration box 1 to enter the processing transformer box 203 along the injection bent pipe 221, so as to realize oil reflux, when the liquid level rises, the hydraulic pressure pushes the sliding seal 228 to reset to the inside of the isolation limit ring 236; When the temperature of the oil in the transformer box 203 is high, the oil in the transformer integration box 1 is extracted through the internal pump 231 and the internal and external inlet and outlet pipes 208, and the oil is directly sprayed to the side end of the transformer core 205 along the hollow support rod 204, the liquid inlet pipe rack 206 and the flushing fixed bucket 207, directly flushing and cooling the surface of the transformer core 205. At this time, the internal oil volume increases, so the above-mentioned operation of discharging the oil is repeated, and the oil extracted from the transformer integration box 1 is returned to the transformer integration box 1. When the oil in the transformer integration box 1 expands, the oil pushes the sliding sealing pad 228 at the position of the upper row of processing pipes 225, and the hot oil is discharged into the storage buffer box 223 along the upper row of processing pipes 225. When the oil in the transformer integration box 1 is reduced to a specified amount, the spring reset rod 227 drives the sliding sealing pad 228 to move along the isolation limit ring 236, opens the reflux processing pipe 224, and the oil flows back to the transformer integration box 1 along the reflux processing pipe 224 and the external processing port 226, realizing the circulation of the oil. The internal environment is cooled by the circulation of the oil. The internal pump 231 and the double processing pipe rack 230 extract the oil at the position of the external cooling circulation rack 229, and spray the oil from top to bottom to realize heat exchange treatment. The external cooling circulation rack 229 and the contact heat exchange rack 232 are used to replace the internal heat. When the external air blows the contact heat exchange rack 232, the air is dispersed and contacted through the counter-slanted holes 233 to increase the cooling contact time, realize the coordinated treatment of air cooling and water cooling, and improve the cooling effect and efficiency.
