Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and specifically to a decentralized transformer cooling system and method thereof. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, etc. Transformers are basic equipment for power transmission and distribution and are widely used in industries, agriculture, transportation, urban communities, and other fields.

[0003] The patent with the application number 202211119675.9 mentions "a transformer cooling system". This patent forms a closed circulation loop through the transformer oil tank, the first oil collecting pipe, the second oil collecting pipe, and the radiator fins to reduce the hot spot temperature inside the main transformer and ensure the safe and stable operation of the main transformer.

[0004] However, when existing small oil-immersed transformers are in use, due to the lack of oil circulation components, during internal cooling, heat is concentrated at the transformer core, resulting in poor heat exchange efficiency. Moreover, only air cooling is used on the outside of the transformer, making the efficiency of discharging internal heat poor. At the same time, when existing oil overflows, it cannot be recycled, and the oil cannot be replenished, which not only affects the operating environment of the transformer but also causes the oil level to drop, affecting the heat exchange efficiency and greatly affecting the stable operation of the transformer.

[0034] According to the above technical solution, a decentralized transformer cooling method, according to the usage method of a decentralized transformer cooling system, includes the following steps:

[0035] S1: Equipment combination: Fix and install the cooling treatment box through a combination screw and an internal thread fixing block, fix and install the integrated support rod and the processing transformer box with a fixing bolt, combine the fitting treatment plate and the cooling operation box with a combination screw and a fixing nut, and combine the load-bearing mounting frame and the cooling operation box with a fixing nut and a bidirectional screw to realize equipment installation and processing;

[0036] S2: Internal cooling: Conduct heat outward through the internal air circulation frame, the decentralized heat exchange frame and the processing transformer box, absorb heat from the transformer core by means of the transformer oil filled inside, and drive the internal oil to flow by the circulation pipe frame and the circulation oil pump to realize internal cooling and temperature equalization processing;

[0037] S3: Dual cooling: Spray transformer oil to the transformer core through an internal pump and an internal and external inlet and outlet pipe, a hollow support rod, a liquid inlet pipe frame and a flushing fixing bucket, and realize internal and external oil exchange cooling processing through external liquid inlet cooling, an external discharge buffer barrel, an external discharge operation pipe, an internal storage buffer barrel and an external discharge linkage pipe. Cooperate with the dual processing pipe frame and the internal pump to drive the oil circulation at the position of the external cooling circulation frame to realize internal and external circulation cooling and temperature equalization processing;

[0038] S4: Circulation mixing: The oil expands and is discharged externally. The transformer box and the transformer integration box are processed through a series of barrels such as an external discharge buffer barrel, an external discharge operation pipe, an internal storage buffer barrel and an external discharge linkage pipe. The transformer integration box and the storage buffer box are connected in series through a reflux processing pipe and an upper row processing pipe to realize internal environment buffer processing and internal and external oil circulation exchange processing, and improve the cooling speed.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] 1. An internal and external cooling circulation component is provided, which contacts the oil in the variable voltage integration box through the internal hollow circulation frame and the dispersed heat exchange frame. The circulation pipe frame and the circulation oil pump drive the two-way flow of the oil in the treatment variable voltage box, enabling the internal position exchange of the oil in the treatment variable voltage box, driving the oil flow, and cooperating with the internal extraction pump, the liquid pipe frame, the flushing fixed bucket, the internal and external inlet and outlet pipes, and the internal hollow circulation frame to inject the oil in the variable voltage integration box into the treatment variable voltage box. The oil is used to directly cool the transformer core. Through the self-circulation flow of the internal oil, the oil is driven to scour the transformer core, improving the cooling speed of the transformer core. The double-connected treatment pipe frame, the internal extraction pump, and the external cooling circulation frame are used to drive the oil in the variable voltage integration box to circulate, achieving multi-position circulating 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, the internal and external oil exchange treatment is realized, thereby increasing the heat exchange area, 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;

[0041] The hot expansion overflow oil in the treatment variable voltage box is discharged and stored through the external discharge buffer barrel, the external discharge operation pipe, the internal storage buffer barrel, and the external discharge linkage pipe, and the oil is injected into the variable voltage integration box. The blocking fixed ring, the bidirectional moving frame, the inserted sealing block, and the spring return rod are used for limit treatment to achieve internal and external isolation while collecting and treating the overflow oil. The return treatment pipe and the upper row treatment pipe are used to overflow the hot oil in the variable voltage integration box into the storage buffer box. The spring return rod, the sliding sealing pad, and the isolation limit ring are used to realize oil overflow and oil injection, which not only increases the heat dissipation area of the transformer but also avoids the influence of oil overflow on the operating environment. At the same time, the oil liquid level is controlled in real time according to the temperature, and effective cooperation can be achieved during the oil circulation cooling, thus ensuring the stability of the transformer operating environment and the stability of the oil liquid level;

[0042] Through the mutual cooperation of the internal self-circulation of the double-box oil and the internal and external coordinated circulation, cooperating with the liquid circulation scouring cooling of the transformer core and the external multi-point air cooling treatment, the internal and external heat exchange treatment is realized, and at the same time, the internal temperature is balanced. The oil control is realized by using the external overflow device and the return device, effectively solving the problems in the prior art that due to the inability of the oil to circulate, the heat is concentrated at the position of the transformer core, resulting in the inability to evenly process the internal temperature, and only through external air cooling treatment, the heat dissipation efficiency is poor. At the same time, by using oil overflow and oil liquid level control, the heat exchange area is increased, avoiding the influence of 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 stable operation treatment of the transformer.

[0043] 2. A double-cooling support component is provided. The cooling treatment box and the inserted heat exchange cylinder are clamped to the top of the transformer integration box through the internal thread fixing block, so that the cooling treatment box and the segmented heat exchange fins are fixed to the top of the transformer integration box. The inserted heat exchange cylinder and the cooling operation box are combined with the transformer integration box by the fixing nut and the combined screw rod. The bearing mounting frame and the cooling operation box are fixedly connected by cooperating with the fixing nut and the bidirectional screw rod. The embedded heat exchange fins are embedded into the bearing mounting frame to realize the combined positioning of the equipment, ensuring the stability of the equipment connection and the convenience of installation. Heat exchange is achieved by contacting the segmented heat exchange fins, the cooling treatment box, the inserted heat exchange cylinder with the transformer integration box and the storage buffer box, realizing heat exchange treatment at the top of the transformer. Heat exchange is carried out on the bottom of the transformer integration box through the cooling operation box, the inserted heat exchange cylinder, the heat exchange contact frame, the bearing mounting frame and the air inlet and outlet holes. By using contact heat exchange, liquid cooling treatment and external wind cooling circulation treatment, cooling treatment at the bottom of the transformer is realized. By using two-way heat dissipation and heat exchange treatment at the top and bottom, the heat exchange area and efficiency of the transformer are increased, and its cooling efficiency is improved.

[0044] In summary, through the mutual cooperation of the internal and external cooling circulation components and the double-cooling support components, by utilizing the internal oil liquid circulation treatment of the transformer, the speed of outward heat conduction is increased. In cooperation with the multi-point contact air cooling and liquid cooling heat exchange at the external side, top and bottom, the cooling area of the transformer is greatly increased, the cooling speed is effectively improved, and the stable operation of the transformer is ensured.

The fixing bolt 201 fixedly installs the integrated support rod 202 and the treatment transformer box 203. The combination screw 305 and the cooling operation box 307 are combined through the fixing nut 316. The fixing nut 316 and the bidirectional screw 312 combine the load-bearing mounting frame 311 and the cooling operation box 307 to realize equipment installation and processing;

[0078] S2: Internal cooling: Heat is conducted outward through the internal empty circulation frame 209, the dispersed heat exchange frame and the treatment transformer box 203, and the transformer core 205 is cooled by absorbing heat with the transformer oil filled inside. The internal oil fluid is driven to flow by the circulation pipe frame 210 and the circulation oil pump 211 to realize internal cooling and temperature equalization processing;

[0079] S3: Dual cooling: The transformer core 205 is sprayed with transformer oil through the internal suction pump 231 and the internal and external inlet and outlet pipes 208 to the hollow support rod 204, the liquid inlet pipe frame 206 and the flushing fixing bucket 207. External liquid inlet cooling, the external discharge buffer bucket 214, the external discharge operation pipe 215, the internal storage buffer bucket 216 and the external discharge linkage pipe 217 are used to realize internal and external oil fluid exchange cooling processing. The dual processing pipe frame 230 and the internal suction pump 231 are used to drive the oil fluid circulation at the position of the external cooling circulation frame 229 to realize internal and external circulation cooling and temperature equalization processing;

[0080] S4: Circulation mixing: The oil fluid expands and is discharged externally. The transformer box 203 and the transformer integration box 1 are processed through the external discharge buffer bucket 214, the external discharge operation pipe 215, the internal storage buffer bucket 216 and the external discharge linkage pipe 217 in series buckets. The transformer integration box 1 and the storage buffer box 223 are connected in series through the return processing pipe 224 and the upper row processing pipe 225 to realize internal environment buffer processing and internal and external oil circulation exchange processing, and improve the cooling speed.

[0081] Working principle and usage process of the present invention: During the installation of the transformer, the staff snaps the cooling treatment box 303 and the inserted heat exchange cylinder 308 onto the top of the transformer integration box 1, and combines and installs the cooling treatment box 303 and the inner-thread fixing block 302 through the limit bolt 315, thereby fixing the cooling treatment box 303 and the fine heat exchange fins 304 to the top of the transformer integration box 1. The inserted heat exchange cylinder 308 at the top of the cooling operation box 307 is embedded into the top of the transformer integration box 1. The fitting treatment plate 306 is sleeved and connected with the combined screw 305, and the fitting treatment plate 306 is fitted to the bottom of the transformer integration box 1. The fixing nut 316 and the combined screw 305 are used to connect the fitting treatment plate 306 and the cooling operation box 307. The hole combination strip 310 at the bottom of the cooling operation box 307 is sleeved into the inner side of the load-bearing installation frame 311, and the bidirectional screw 312 is inserted into the inner sides of the heat exchange contact frame 309 and the hole combination strip 310. The load-bearing installation frame 311 and the cooling operation box 307 are fixedly connected through the fixing nut 316 and the bidirectional screw 312. The inserted heat exchange fins 313 are embedded into the load-bearing installation frame 311 to achieve combined positioning;

[0082] The top of the transformer is heat-exchanged through the fine heat exchange fins 304, the cooling treatment box 303, and the inserted heat exchange cylinder 308 in contact with the transformer integration box 1 and the storage buffer box 223. The bottom of the transformer integration box 1 is heat-exchanged through the cooling operation box 307, the inserted heat exchange cylinder 308, the heat exchange contact frame 309, the load-bearing installation frame 311, and the air inlet and outlet holes 314. By using contact heat exchange, liquid cooling treatment, and external wind cooling cycle treatment, the bottom of the transformer is cooled;

[0083] The external wiring device is powered through the wiring terminal 301. When the transformer core 205 is operating, the transformer core 205 dissipates heat to the transformer oil in the processing transformer box 203. The transformer oil expands when heated. The transformer oil in the processing transformer box 203 expands outward into the outer discharge buffer barrel 214. The oil pushes the inserted sealing block 220 to separate from the blocking fixing ring 218 in the outer discharge operation pipe 215. The oil flows along the outer discharge operation pipe 215 into the memory buffer barrel 216. At this time, the bidirectional moving frame 219 pushes the inserted sealing block 220 to embed into the side end of the blocking fixing ring 218 in the outer discharge linkage pipe 217. At this time, the oil will not discharge from the memory buffer barrel 216 along the outer discharge linkage pipe 217. When the expansion of the processing transformer box 203 ends, the spring return rod 227 drives the bidirectional moving frame 219 to move and reset along the memory buffer barrel 216, and the oil in the memory buffer barrel 216 is communicated with the oil in the transformer integration box 1 through the outer discharge linkage pipe 217, realizing the external discharge and cooling treatment of the oil, buffering the inside of the processing transformer box 203. The oil in the inner cavity circulation frame 209 and the processing transformer box 203 conducts heat to the positions of the inner cavity circulation frame 209 and the dispersion heat exchange frame 212. The transformer oil in the transformer integration box 1 absorbs the heat on the surfaces of the inner cavity circulation frame 209 and the dispersion heat exchange frame 212, realizing the outward export of heat. The circulating oil pump 211 and the circulation pipe rack 210 drive the oil in the inner cavity circulation frame 209 to circulate, realizing the internal liquid flow. At this time, through the self-circulation flow heat exchange of the internal liquid flow, the efficiency of internal heat exchange is improved. When the internal temperature decreases, the liquid level drops. When the liquid level drops to the limited liquid level position of the injection fixed pipe 234, the spring return rod 227 drives the sliding sealing pad 228 to move along the isolation limit ring 236, opening the injection bending pipe 221. The oil in the transformer integration box 1 enters the processing transformer box 203 along the injection bending pipe 221, realizing the oil return. When the liquid level rises, the hydraulic pressure pushes the sliding sealing pad 228 to reset to the inner side of the isolation limit ring 236;

[0084] When the oil temperature in the transformer box 203 is relatively high, the oil in the transformer integration box 1 is extracted through the internal extraction pump 231 and the internal and external inlet and outlet pipe 208. The oil flows along the hollow support rod 204, the liquid inlet pipe rack 206 and the flushing fixed hopper 207 and is directly sprayed onto the side end of the transformer core 205, directly flushing and cooling the surface of the transformer core 205. At this time, the internal oil volume increases, so the above 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 gasket 228 at the position of the upper row of treatment pipes 225, and the hot oil is discharged into the storage buffer box 223 along the upper row of treatment pipes 225. When the oil in the transformer integration box 1 drops to the limited amount, the spring return rod 227 drives the sliding gasket 228 to move along the isolation limit ring 236, opening the return treatment pipe 224, and the oil flows back into the transformer integration box 1 along the return treatment pipe 224 and the external discharge port 226, realizing the circulating flow of the oil. By using the circulating flow of the oil, the internal environment is cooled. The internal extraction pump 231 and the double-link treatment pipe rack 230 extract the oil at the position of the external cooling circulation rack 229, and the oil is sprayed and flows from top to bottom to realize the heat exchange treatment, cooperating with the external cooling circulation rack 229 and the contact heat exchange rack 232 to carry out the internal heat replacement treatment. When the external air blows on the contact heat exchange rack 232, the air is dispersed and contacted through the counter-flush inclined holes 233 to increase the cooling contact time, realizing the combined treatment of air cooling and water cooling and improving the cooling effect and efficiency.
