Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a multifunctional amorphous alloy transformer for power distribution. Background Technology

[0002] Amorphous alloy transformers are a new generation of high-efficiency, energy-saving, and intelligent power equipment with amorphous alloy materials as the core. A Chinese patent discloses an amorphous alloy distribution transformer with noise reduction function, application number: CN202220392076.3. It has a good sound absorption and sound insulation effect by setting a sound-absorbing plate in the interlayer between the inner and outer boxes, reducing the noise during transformer operation. The heat is dissipated from the inside of the box by the heat-conducting block, giving the transformer a good heat dissipation effect. However, current amorphous alloy transformers are prone to dimensional fluctuations due to magnetostriction and thermal expansion and contraction during operation, causing internal vibrations. There is a lack of effective limiting and protection mechanisms to constrain these fluctuations and compensate for dimensional deviations. In addition, the influence of external vibration disturbances not only easily generates noise, but also makes the internal structure of the transformer prone to loosening. Amorphous alloys are also prone to generating debris during operation, causing partial discharge and ultimately leading to insulation collapse. Summary of the Invention

[0014] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use; 1. Equipped with a balance maintenance mechanism, the suspension frame can be formed by the base, panel, side plate and suspension seat, which can provide stable foundation support for the iron core. On the one hand, it can cooperate with crossbars, frames, sleeves, support rods, pads, compression springs, clamps and sleeves to provide elastic support to the outside of the iron core and provide elastic auxiliary limit to the iron core, so that it can be stably suspended inside the transformer box. It can not only effectively limit the vibration displacement amplitude of the suspension frame during transformer operation, effectively ensure the relative orientation stability of the iron core and the transformer, and avoid hard squeezing and collision, but also use the spring force to synchronously buffer the internal and external vibration buffer force, further consume the remaining vibration force, and can be combined with the resistance and force transmission effect of transformer oil to form an external buffer protection mechanism. It not only effectively disperses and mitigates vibration and impact forces, preventing stress concentration, but also works in conjunction with hanging rods, limiting plates, and limiting springs. Combined with the limiting and guiding effects of crossbars and tension springs, as well as the elastic expansion and contraction of the protective pads, it ensures the suspension guard maintains an inward contraction trend during use. This effectively strengthens the fit between the spacers and pads and the iron core, achieving enveloping limiting protection, preventing debris from scattering, and forming inner limiting protection. It provides bidirectional auxiliary consumption of lateral and longitudinal disturbance forces, adaptively compensating for dimensional deviations in the iron core caused by magnetostriction and thermal expansion and contraction during operation. Coupled with an outer buffer protection mechanism, it provides multiple three-dimensional protection, achieving stable force dissipation and reducing vibration while preventing direct hard compression and impact. Furthermore, the external limiting protection mechanism composed of the base, corner ribs, side pads, and bottom pads achieves dual synchronous buffer protection both inside and outside.

[0015] 2. Equipped with a circulating stabilization mechanism, the bottom screening structure is formed by the cooperation of the ring box, bottom box, guide tube, screen cylinder, filter plate and filter screen. It can periodically purify and remove impurities from the transformer oil during long-term operation of the transformer. It can make full use of the screening and interception function of the filter plate to effectively intercept and collect amorphous alloy debris during the transformer oil circulation process. With the directional driving action of the circulating pump and the directional flow guidance action of the bottom pipe, side pipe, pilot valve, conveying pipe, top pipe, wall groove, guide groove and sliding pipe, a complete transformer oil circulation path can be formed. It can directly flush the iron core during the operation of the transformer. It can not only directly wash away the amorphous alloy debris that falls off the iron core during long-term operation, but also achieve direct and timely discharge of debris, avoiding the accumulation of debris that affects the electrical insulation performance. Furthermore, it can directly remove the heat dissipated from the core during transformer operation, achieving efficient auxiliary heat dissipation and significantly improving the stability of transformer operation. Through the cooperation of turbine, angle rod, and rod sleeve, it can provide a stable directional driving force for the scraper. In addition, the elastic support of the sleeve rod, slide rod, slider, and support spring can make the scraper fit the filter screen more closely, and can achieve synchronous cleaning of the filter screen during periodic purification and impurity removal. It can effectively prevent debris from adhering and affecting the permeability of the filter screen, ensuring the stability of amorphous alloy debris circulation and transfer, while making the circulation flow of transformer oil smoother. Through the cooperation of screen cylinder, filter plate, filter screen, and plug rod, it can achieve centralized cleaning of amorphous alloy debris during transformer maintenance, achieving more efficient and stable maintenance.

[0016] In summary, during operation, this transformer ensures that the core remains stably suspended inside the transformer box, achieving composite suspension and multi-point buffering. It provides synchronous internal and external protection, achieving multiple dissipation and distributed balance of vibration impact forces, cutting off the rigid transmission path of vibration, and providing multiple three-dimensional protection for the core. While achieving encapsulated elastic constraint and reducing vibration disturbance, it can adaptively compensate for dimensional deviations caused by magnetostriction and thermal expansion and contraction, avoiding direct hard compression and impact on the core, preventing amorphous alloy debris from affecting electrical insulation performance, and timely transferring debris to improve the transformer's operational stability.

The plug rod 324 is a semi-threaded screw, and the end of the plug rod 324 is sealed and inserted into the slide tube 315 to clean amorphous alloy debris.

[0023] The working principle and usage process of this invention are as follows: Before using this multifunctional amorphous alloy transformer for power distribution, firstly, according to the actual power distribution requirements, select a transformer with the appropriate specifications and parameters, and transport the transformer to the work area. The transformer box 1 is fixedly installed in the work area by the base 219 and the corner rib 220. After completing the corresponding wiring connection work, rotate the plug rod 324 so that its end is disengaged from the sliding tube 315, thereby releasing the blockage on the sliding tube 315 and allowing the transformer oil to pass freely. Then the transformer can be put into use. During the operation of the transformer, under the elastic compression of the compression spring 213, the pad 212 will push the support rod 211 out of the sleeve 210, and the support rod 211 will press against the clamping plate 214, so that the sleeve 215 will come into contact with the transformer box 1. Then the transformer box 1 will give the clamping plate 214 a reverse elastic support force, which will assist in limiting the frame 209 and form an outer buffer protection. Furthermore, under the limiting support of the crossbar 208, the suspension guard frame formed by the base 201, the panel 202, the side plate 203 and the suspension seat 204 will obtain synchronous limiting support force and be stably suspended in the middle of the inner cavity of the transformer box 1. At the same time, under the elastic support of the tension spring 223, the side plate 203 will always slide along the cross bar 208, moving closer to the base 201 and the suspension seat 204, simultaneously pressing the pads 207 on the outside of the base 201, panel 202 and suspension seat 204. Under the elastic support of the limiting spring 218, the limiting plate 217 will also always move along the hanging rod 216, moving closer to the suspension seat 204, pressing against and fitting against the panel 202. Furthermore, while ensuring the stability of the suspension guard frame formed by the base 201, panel 202, side plate 203 and suspension seat 204, it can provide stable elastic support to the suspension guard frame, so that the suspension guard frame always maintains the tendency to shrink inward, so that each spacer 205 is subjected to synchronous compression. In addition, the spacer 205 will press against the iron core 11 through the pad strip 206, giving it flexible limiting support and dynamically limiting it to the inside of the suspension guard frame, thus achieving inner limiting protection. Similarly, during the use of the transformer, the base 219 will support the bottom of the transformer box 1 through the bottom pad 222, and the corner rib 220 will abut against the four corners of the transformer box 1 through the side pad 221, limiting the transformer box 1 from the outside and achieving external protection. In addition to the internal protection mechanism composed of the outer buffer protection and the inner limit protection mentioned above, double buffer protection can be achieved. Furthermore, during the operation of the transformer, when the transformer is subjected to external vibration and impact due to the vibration interference of passing vehicles and wind disturbance, the external vibration and impact force will first act on the base 219 and corner rib 220. After being buffered by the side pad 221 and bottom pad 222, most of the impact force will be dissipated before it is transmitted to the transformer box 1. In addition, since the sleeve 215 is pressed against the transformer box 1 under the pressure of the compression spring 213, under the limiting action of the transformer box 1, the clamping plate 214 and the support rod 211 will always remain relatively stationary with respect to the transformer box 1. Furthermore, under external impact, since the frame 209 can slide relative to the support rod 211, it will have a relative sliding tendency. Further, driven by the frame 209, the sleeve 210 will have a relative sliding tendency with the support rod 211, compressing the compression spring 213, further relieving and buffering the remaining impact force. When the remaining external impact force is sufficient to offset part of the elastic force of the compression spring 213, causing the frame 209 to shift relative to the transformer box 1; Since the external impact force has been consumed twice in the aforementioned process, under the linkage of the crossbar 208, the suspension guard formed by the base 201, panel 202, side plate 203 and suspension seat 204 will only cause the iron core 11 to move slightly, and with the help of the external transformer oil resistance, the residual force will be further consumed and the impact stress will be dispersed and resolved. Meanwhile, during this process, the tension spring 223 will also consume lateral disturbance force and assist in balancing the lateral disturbance force while ensuring the connection stability of the suspension guard formed by the base 201, panel 202, side plate 203 and suspension seat 204. The limit spring 218 will consume longitudinal disturbance force and assist in balancing the longitudinal disturbance force during this process. In addition, the frame 209 will simultaneously pull and compress each compression spring 213, and the transformer oil can enter the sleeve 210 through the end hole of the sleeve 210 to provide auxiliary support to the pad 212, which can further resolve and disperse the external impact force. Under the limit of the suspension guard, the iron core 11 can always be suspended in the middle of the inner cavity of the transformer box 1, and it is protected in three-dimensional space with multiple three-dimensional protection to avoid it from being directly squeezed and impacted. Correspondingly, during the operation of the transformer, it is inevitable that the transformer will vibrate due to electromagnetic shock and undergo pressure changes due to thermal expansion and contraction. That is, the iron core 11 will undergo periodic dimensional expansion and contraction under the action of alternating magnetic field. The winding 12 and other components outside the iron core 11 will also undergo dimensional expansion and contraction under temperature fluctuations. In this process, internal vibration will inevitably occur. At this time, the spacer 205 hugs the iron core 11 through the pad 206, further balancing the external impact force and further buffering the external impact force. The spacer 205 will also follow the iron core 11 to adapt to elastic expansion and contraction, adapting to the size fluctuation of the iron core 11 caused by the periodic size expansion and contraction under the action of alternating magnetic field, realizing flexible covering and limiting, and transmitting the disturbance force generated by internal vibration in the opposite direction along the transmission path of the disturbance force generated by external vibration. Furthermore, the elastic force of the limiting spring 218, tension spring 223 and compression spring 213, the resistance of the transformer oil, and the limiting support force of the protective pad 207 and sleeve 215 can be used to gradually consume the vibration from the inside out, reducing the noise and vibration generated. During this process, the gap between the pads 206 will provide the pads 206 with more redundant buffer space during the deformation of the spacer 205 and the pads 206, so that they can consume the internal vibration force more fully and avoid the iron core 11 being damaged due to vibration and dimensional expansion and contraction, and the collision and squeezing with the limiting components. During the long-term use of the transformer, even with multiple three-dimensional protections on the core 11 in three-dimensional space to simultaneously consume internal and external vibration disturbances, the characteristics of the amorphous alloy mean that the core 11 will inevitably produce debris after long-term use. Therefore, the circulating pump 308 can be periodically started during the use of the transformer. After the circulating pump 308 is started, it will generate directional conveying force. The transformer oil inside the transformer box 1 will flow to the bottom spontaneously under the action of gravity. It will flow along the guide groove 314 and through the slide pipe 315 into the inner space of the screen cylinder 304. During this process, debris will also enter the inner space of the screen cylinder 304 along with the transformer oil. Then the transformer oil will pass through the filter screen 306 and enter the base 201. After being further filtered by the non-woven fabric inside the base 201, it will enter the bottom box 302 through the conduit 303. Most of the debris will be trapped inside the screen cylinder 304 by the filter screen 306. A very small amount of fine debris will also be intercepted by the non-woven fabric. Driven by the circulating pump 308 and under the influence of gravity, the transformer oil that enters the bottom box 302 will then enter the bottom pipe 307, and then pass through the side pipe 309, the pilot valve 310, and the conveying pipe 311 into the suspension seat 204. With the connection of the top pipe 312, it will be injected into each partition 205 simultaneously, and directly flush the iron core 11 along the wall groove 313. While carrying away the debris that falls off the iron core 11, it will also carry away the heat. Then, the transformer oil carrying the debris will be guided again by the guide groove 314 and injected into the inner space of the screen cylinder 304 through the slide pipe 315 to circulate and purify the transformer oil, remove debris, and indirectly promote heat exchange inside and outside the transformer. During the circulation of transformer oil, the turbine 316 inside the bottom box 302 rotates under the drive of the transformer oil. Furthermore, it drives the sleeve 318 to rotate through the angle rod 317. The sleeve rod 319 and the slide rod 320 also rotate synchronously. Under the pressure of the support spring 322, the slider 321 pushes the scraper 323 through the slide rod 320, so that the scraper 323 fits against the filter screen 306. Then, during the rotation of the slide rod 320, the scraper 323 can simultaneously scrape the filter screen 306 to prevent the filter screen 306 from clogging, and the debris falls into the screen cylinder 304 for centralized collection. During the long-term use of the transformer, when performing regular maintenance, rotate the plug rod 324 so that its end is inserted into the slide tube 315 to block the slide tube 315, preventing the transformer oil from flowing. After removing the ring box 301, remove the rod sleeve 318, take out the screen cylinder 304, remove the debris, and replace the non-woven fabric inside the ring box 301. Then, reset the ring box 301 and the plug rod 324 in sequence to complete the centralized removal of debris and prevent the debris from affecting the insulation performance of the transformer.
