[0002] Amorphous alloy transformer is a low-loss, high-efficiency power transformer. This type of transformer uses iron-based amorphous metal as the core. Since this material does not have a long-range ordered structure, its magnetization and demagnetization are easier than general magnetic materials.

[0003] The patent with application number 202311124600.4 mentions "an amorphous alloy transformer with buffering function". This patent uses a damper and a shock-absorbing spring for buffering to reduce the impact of wire shaking on the terminal head and the transformer body.

[0004] However, when the transformer is used now, it is only protected by wiring buffers. The vibration caused by the uneven running speed of components and the conversion of the transformer environment during operation, as well as the vibration of internal components caused by the uneven cooling speed of silicon steel sheets and windings, are not dealt with. As a result, the equipment will vibrate greatly as a whole during operation, making many parts of the equipment prone to vibration looseness and damage.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. A protective component is provided, and the transformer core is supported by limiting springs, load-bearing matching frames, limit dampers and elastic raised plates. The core running inside the transformer is subjected to energy absorption treatment by limiting springs and elastic raised plates to reduce the kinetic energy of internal vibration. The internal solid processing box is subjected to vibration reduction treatment by protective springs, fixed finger force device box elastic rubber blocks, and the potential energy generated by the internal solid processing box is dispersed and absorbed, and the vibration potential energy transmitted from the inside to the outside is absorbed again to further reduce the vibration of the equipment. The sliding socket box and the sliding alignment frame are supported and restricted by linkage springs and compression dampers. The protective gaskets and contact rubber plates are used for energy absorption and buffering to achieve external connection support and external connection isolation, reduce the impact of external impact on the inside, and reduce the impact of internal vibration on external connection. The potential energy generated by vibration is dispersed by multi-stage linkage coordination to avoid resonance between equipment and vibration, effectively protect the running parts of the transformer, improve the stability of the connection, and reduce the noise generated by vibration.

[0031] The oil pump, circulating serpentine pipe rack, special-shaped external pipe, inserted multi-row pipe rack and linkage limiting valve drive the oil in the internal solid treatment box to circulate, and spray the oil directly between the silicon steel sheet and the winding. The oil pump and U-shaped circulating pipe drive the oil in the external solid integration box to circulate, and the internal integrated heat sink and the external heat sink increase the heat dissipation area. Circulating cooling and direct spray cooling are used to even out the cooling speed and temperature at multiple locations. The three-stage cooling of internal self-circulation, external contact circulation and natural air cooling circulation cooperate with each other to improve the overall cooling and heat exchange effect, reduce the occurrence of thermal expansion collision caused by uneven cooling and insufficient cooling speed, and then use sound-absorbing panels and sound-absorbing treatment panels to perform three-stage sound absorption treatment on the inside and outside to reduce the noise from the inside to the outside and improve the stability of equipment operation.

[0032] Through the internal two-stage energy absorption buffer, combined with the internal multi-position elastic buffer, and the use of circulating cooling and fixed-point direct injection cooling, the internal cooling speed and the temperature of the equipment itself are balanced, and the mechanical noise generated by the operation of the transformer is reduced. Through the internal and external three-stage sound absorption treatment, the noise generated by the electromagnetic environment is reduced. It effectively solves the problem in the prior art that the equipment generates large vibrations and noises due to factors such as magnetic field changes, electromagnetic force imbalance, and uneven cooling speeds of silicon steel sheets and windings. It avoids the resonance reaction of the equipment due to the influence of vibration and noise, realizes the protection of transformer components, reduces the speed of component damage, and cooperates with circulating cooling and three-stage linkage cooling to effectively reduce the temperature of the transformer during continuous operation, improve the service life of the transformer, and use vibration reduction and noise reduction synchronous operation to reduce the impact of noise on the operating environment.

[0033] 2. An external discharge reflux component is provided. The oil vapor pushes the inserted clamping block to separate from the clamping elastic ring. At this time, the pressure-limiting spring is compressed, and the oil vapor enters the external discharge fixed pipe and the sleeve support pipe. The inserted clamping block is limited by the pressure-limiting springs at both ends, and the internal oil vapor is discharged outward. The inserted clamping block is limited by two sets of pressure-limiting springs, and the I-type plug-in frame is limited by the pressure-limiting spring. The exhaust position is adjusted according to different pressures to achieve three-stage exhaust, gradually adjust the internal pressure, and increase the range of pressure regulation. The inside of the transformer is monitored in conjunction with the contact alarm and the pressure-bearing impact plate to ensure the stability of the internal environment of the transformer. The support cylinder and the external limit collection barrel are heat-exchanged with the outside to achieve oil vapor condensation recovery and internal and external isolation to avoid the pollution of the transformer by the external environment. At the same time, oil recovery is achieved. The oil inside the transformer is monitored by the liquid level gauge, and the injection operation pipe and the oil storage box are controlled by the processing limit valve to inject liquid into the external solid integration box and the internal solid processing box to achieve oil replenishment, ensure the stability of the liquid level, and avoid the low liquid level affecting the cooling and protection of the transformer.

[0034] In summary, through the cooperation of protection components and external exhaust reflux components, oil circulation cooling treatment and oil flow sound absorption are used to achieve internal stable cooling and noise reduction treatment. At the same time, with the internal exhaust and external reflux treatment, the voltage stabilization operation can be achieved while ensuring the stability of the oil volume inside the transformer, ensuring that the equipment is always in the transformer oil, avoiding exposure that affects cooling, and through the cooperation of multiple combinations, the steady operation of cooling, heat exchange, noise reduction and vibration reduction is guaranteed, effectively improving the stability and safety of equipment operation.

The high heat is transferred to the transformer oil through the winding coil and silicon steel sheet of the transformer core 214. At this time, due to the influence of factors such as the power supply voltage state, current direction and electromagnetic interference, the transformer core 214 will produce slight vibration;

[0067] The load-bearing frame 212 connected by the fixing nut 213 absorbs energy under the action of the limiting spring 211, absorbs the large-amplitude vibration potential energy and releases it in sections, thereby converting the large-amplitude vibration into small-amplitude vibration, and cooperates with the limit damper 215, the limit support plate 216 and the elastic protruding plate 217 for buffering support, and uses the limit damper 215 for positioning support to avoid the internal transformer core 214 from tilting and misalignment. At the same time, when it vibrates, the elastic protruding plate 217 elastically supports and absorbs energy, and the elastic deformation of the elastic protruding plate 217 is used to absorb and disperse the potential energy generated by the vibration, thereby further reducing its vibration amplitude. When the equipment vibrates, the combined sealing tube 209, the externally threaded threading tube 207 and the sealing rubber ring 226 are mutually fitted, and the combined sealing tube 209 and the externally threaded threading tube 207 are slidably fitted to realize vibration transposition adjustment, ensuring that there will be no large-amplitude collision between components during overall vibration, thereby avoiding the situation where the components collide with each other to increase vibration and noise;

[0068] At the same time, the protective spring 201 at the bottom of the inner solid processing box 202 absorbs the energy of the inner solid processing box 202, cooperates with the fixed damper 204 and the elastic rubber block 205 to support the top sealing fixed plate 203, reduces its vibration amplitude, and absorbs and disperses the potential energy of vibration through the elastic rubber block 205 and the sealing rubber ring 226, thereby further reducing the amplitude of vibration and improving the overall operation stability of the equipment. At the same time, by reducing the amplitude of vibration and absorbing the potential energy generated by vibration, the noise generated by equipment collision and metal resonance is effectively reduced;

[0069] The silicon steel sheets in the transformer core 214 will separate or collide due to the heated components, generating noise and vibration. The oil pump 224 and the circulating serpentine tube rack 219 extract the oil in the inner solid treatment box 202, and the oil is discharged outward along the circulating serpentine tube rack 219, the special-shaped external discharge pipe 220 and the inserted multi-row tube rack 221. The linkage control valve 222 controls the special-shaped external discharge pipe 220 and the inserted multi-row tube rack 221 to flush the side end of the transformer core 214, driving the oil to circulate from bottom to top, and the oil is used to directly impact the winding and the side end of the silicon steel sheet at the position of the transformer core 214, realizing direct impact cooling of the contact point, reducing the dislocation collision of the silicon steel sheet caused by uneven cooling speed, and using the circulating serpentine tube rack 219 and the internal integrated heat dissipation rack 218 to transfer the heat in the inner solid treatment box 202 to the oil in the outer solid integration box 1, and realizing steady heat exchange treatment by flow heat exchange and fixed-point heat exchange;

[0070] The oil in the outer solid integration box 1 is driven to circulate through the oil pump 224 and the U-shaped circulation pipe 223, and the outer heat dissipation rack 228 is used to conduct heat outward to achieve internal and external heat exchange, ensuring that the temperature in the outer solid integration box 1 is uniform and stable. The heat on the surface of the outer heat dissipation rack 228 passes through the external flowing air, and the dispersed exhaust holes 229 are used to guide the external airflow to increase the contact area. In addition, through multi-directional exhaust, a steady heat exchange process is achieved inside and outside, thereby improving the effect of heat exchange.

[0071] The sound absorbing plate 225 is used to absorb sound inside the external solid integration box 1 and the internal solid processing box 202, and the external sound absorbing processing plate 230 is used to absorb sound on the side end of the external heat dissipation frame 228 and the external solid integration box 1, so as to reduce the occurrence of noise discharge. The sliding sleeve box 231 slides and changes position along the sliding alignment frame 233 under the limiting action of the linkage spring 234 and the compression damper 232, and cooperates with the protective gasket 235 for elastic support, so as to realize the external support limit, ensure the stability of the overall support alignment, and reduce the occurrence of shaking and collision of the transformer due to external influences;

[0072] During the continuous operation of the transformer, the oil inside the transformer is monitored by the liquid level meter 304. When the internal oil level is lower than the standard level, the injection operation pipe 302 is opened by the processing limit valve 303, and the oil in the oil storage tank 301 is injected into the outer solid integration box 1 and the inner solid processing box 202 along the injection operation pipe 302 to achieve oil replenishment, ensure the stability of the liquid level, and avoid the liquid level being too low to affect the cooling and protection of the transformer;

[0073] During continuous operation, due to the continuous high temperature inside, the oil will evaporate. The evaporated oil vapor will increase the pressure inside the outer solid integration box 1 and the inner solid processing box 202. The internal air pressure pushes the insertion clamping block 312 at the position of the outer fixed pipe 305 to separate from the clamping elastic ring 307. The insertion clamping block 312 slides up and down along the double-hole fixed plate 310. At this time, the pressure-limiting spring 311 located in the outer fixed pipe 305 is compressed, and the oil vapor enters the outer fixed pipe 305 and the sleeve support pipe 306. The oil and gas enter the inner side of the sleeve support pipe 306, and after heat exchange and cooling with the outside, it condenses into transformer oil again, realizing the reflux of transformer oil, and utilizing the internal isolation environment to avoid the situation where the internal and external communication of the transformer affects the internal environment.

[0074] The internal oil vapor is discharged outwardly, and is limited by two sets of pressure-limiting springs 311 and the inserted locking block 312. The pressure-limiting springs 311 cooperate with the I-type plug-in frame 313, and the external discharge operation hole 314 is used to discharge the oil vapor outward, so as to realize three-stage exhaust. Different levels of operation are performed according to different internal pressures. When the internal pressure is too high, the I-type plug-in frame 313 is pushed to contact the contact alarm 316 to realize alarm processing. At the same time, the oil vapor enters the inner side of the outer limit collection barrel 315, increasing the pressure in the outer limit collection barrel 315. The pressure-bearing impact plate 317 will be shattered by the impact under the action of pressure, so as to realize steady external discharge processing, ensure the stability of the internal pressure, reduce the impact of pressure on the internal environment, and improve the stability of transformer operation.
