Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a low-energy-consumption, high-impedance transformer and its usage method. Background Technology

[0002] With the continuous development of the power transmission and distribution and new energy grid connection industries, the application scenarios of low-energy-consumption, high-impedance transformers are constantly expanding. During the operation of transformers, dust and debris easily accumulate on the surface of the heat sink. Dust accumulation will hinder heat dissipation, aggravate temperature rise, and increase transformer energy consumption. Therefore, a reliable structure is needed to regularly clean the transformer heat sink casing to ensure the equipment continues to operate stably with low energy consumption.

[0003] However, most existing transformers lack a cleaning mechanism for the heat dissipation casing during use. Over time, dust and impurities tend to accumulate on the heat sinks, hindering heat dissipation, affecting the heat dissipation efficiency of high-impedance transformers, and consequently affecting the stable operation of the equipment and increasing operating energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a low-energy-consumption high-impedance transformer and its usage method. By setting up a cleaning section, the invention solves the problem that most existing transformers lack a cleaning mechanism for the heat dissipation shell during use. This leads to the accumulation of dust and impurities on the heat sinks over a long period of time, which hinders heat dissipation, affects the heat dissipation efficiency of the high-impedance transformer, and consequently affects the stable operation of the equipment and increases operating energy consumption.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a low-energy-consumption, high-impedance transformer and its usage method, comprising a base plate on which a transformer is mounted, a top plate on which the transformer is mounted, and further comprising: a cleaning section, wherein a plurality of cleaning sections are arranged in an array on the transformer; a retractable handle section, wherein a plurality of retractable handle sections are respectively arranged on the cleaning section; a protective section, wherein a plurality of protective sections are arranged and all are mounted on the top of the base plate; the cleaning section includes a cleaning assembly disposed on the transformer; and a snap-fit ​​assembly. There are two, and the two buckle assemblies are mirror-mounted on the top plate; the cleaning assembly includes two fixing blocks fixedly connected to the bottom plate, a rotating shaft fixedly connected between the two fixing blocks, several rectangular support plates fixedly connected to the outer wall of the rotating shaft, two cleaning blocks fixedly connected to the outer wall of each of the several rectangular support plates, and a rectangular rod fixedly connected to the top of each of the several rectangular support plates; the sides of the several cleaning blocks that are far apart from each other contact the outer wall of the transformer heat sink, the rectangular support plates are all made of thermally conductive material, and the cleaning blocks are made of fluororubber, which is resistant to high temperatures for a long time, has good elasticity, moderate friction, and is not easy to scratch the heat sink.

[0006] Furthermore, the buckle assembly includes a support base fixedly connected to the top of the top plate. An elastic open clamp is fixedly connected to the front side of the support base. A connector is provided on the rear side of the rectangular rod. The connector includes a spherical connector fixedly connected to the rear side of the rectangular rod. The spherical connector is adapted to the elastic open clamp. Specifically, under the action of external force, the ball head squeezes the arc-shaped elastic arms on both sides of the clamp, and the elastic arms elastically open outward. After the ball head is fully embedded in the inner ring of the clamp, the elastic arms rebound and close by their own material. The arc-shaped inner wall wraps around the spherical surface of the ball head and holds the ball by the elastic pre-tightening force to achieve limit locking.

[0007] Furthermore, the retractable handle includes a telescopic assembly disposed on a rectangular rod; a limiting assembly mounted on a fixed block; the telescopic assembly includes a cylindrical rod hinged to the front side of the rectangular rod, a handle disposed on the cylindrical rod, and a cylindrical groove formed on the rear side of the handle; the cylindrical rod is slidably connected to the handle through the cylindrical groove.

[0008] Furthermore, the limiting component includes an elastic block fixedly connected to the front side of the rectangular rod. The elastic block has an arc groove and a friction element. The arc groove is adapted to the handle, and the elastic block can limit and lock the handle through the arc groove. The friction element includes a friction block fixedly connected to the inner wall of the arc groove. The front side of the elastic block is provided with a chamfered edge. The front side of the elastic block is chamfered to form a chamfered edge.

[0009] Furthermore, the protective part includes a U-shaped support block fixedly connected to the top of the base plate. Two side protective plates are fixedly connected to the top of the U-shaped support block, and a front protective plate is fixedly connected between the two side protective plates. The bottom of the front protective plate is fixedly connected to the top of the U-shaped support block. The two side protective plates and the front protective plate form an inverted protective bucket-shaped structure to prevent impurities from entering the hard-to-clean area below the transformer during cleaning.

[0010] Furthermore, the transformer is a 1250kVA oil-immersed high-impedance energy-consuming transformer that operates based on the principle of electromagnetic induction. The core is equipped with a primary winding and a secondary winding. When alternating current is applied to the primary side, an alternating magnetic field is generated, and an electromotive force is induced in the secondary winding to achieve voltage transformation. Unlike ordinary distribution transformers, this transformer has a larger equivalent impedance in its windings. During operation, it relies on the active power loss generated by the winding impedance to dissipate energy, which can play the role of current limiting and absorbing excess electrical energy. The transformer body is filled with insulating oil to achieve insulation and cooling. The heat dissipation fins on the outer shell continuously dissipate the heat generated by the working loss. The high and low voltage insulating bushings on the top are used for external electrical wiring.

[0011] The present invention has the following beneficial effects: (1) By setting up a cleaning section, the present invention drives the cleaning blocks on both sides to rotate synchronously around the axis by relying on the rotating shaft and rectangular support plate, so that the cleaning blocks continuously stick to the outer wall of the transformer heat sink to scrape and clean, which can remove the dust and impurities accumulated on the surface of the heat sink, avoid dust accumulation from hindering heat dissipation, ensure the heat dissipation efficiency of the high impedance transformer, maintain stable operation of the equipment, and reduce operating energy consumption; at the same time, with the cooperation of the rear ball joint and the elastic open clamp, the cleaning component can be quickly positioned and locked after cleaning. (2) The present invention provides a retractable handle. The retractable handle extends and retracts through a sliding telescopic structure between the cylindrical rod and the handle. It is combined with an elastic block, an arc groove and a friction block to form a limiting structure. During cleaning, the handle can be pulled out to obtain a suitable operating torque, which is convenient for manual driving of the cleaning part to rotate. After cleaning, the handle can be retracted and locked in place to avoid the handle being damaged by bumping, accidental contact or swinging due to long-term extension. The handle is retracted and locked, which reduces the space occupied by the exposed equipment and improves the overall safety and neatness of the device. (3) By setting up a protective part, the protective part is composed of a U-shaped support block, a side protective plate and a front protective plate to form an inverted protective bucket structure. During the entire process of the cleaning part scraping off the dust and impurities of the heat sink, it can receive and intercept the falling dirt, prevent dust and debris from falling into the dead corner between the bottom of the transformer and the bottom plate, prevent impurities from accumulating in the difficult-to-clean bottom area for a long time, causing rust and local heat accumulation, reduce the hidden dangers at the bottom of the transformer from the source, and reduce the difficulty of subsequent deep cleaning.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-9 This invention relates to a low-energy-consumption, high-impedance transformer and its usage method, comprising a base plate 111, a transformer 112 mounted on the base plate 111, a top plate 113 mounted on the transformer 112, and further comprising: a cleaning section 2, wherein a plurality of cleaning sections 2 are arranged in an array on the transformer 112; a retractable handle section 3, wherein a plurality of retractable handle sections 3 are respectively arranged on the cleaning sections 2; and a protective section 4, wherein a plurality of protective sections 4 are arranged and all are mounted on the top of the base plate 111.

[0018] The cleaning unit 2 includes a cleaning component 21 mounted on the transformer 112; and two latching components 22 mirror-imagely mounted on the top plate 113. The cleaning component 21 includes two fixing blocks 211 fixedly connected to the bottom plate 111, with a rotating shaft 212 fixedly connected between them. Several rectangular support plates 213 are fixedly connected to the outer wall of the rotating shaft 212, and two cleaning blocks 214 are fixedly connected to the outer walls of each rectangular support plate 213. A rectangular rod 215 is fixedly connected to the top of each rectangular support plate 213. The sides of the cleaning blocks 214 that are furthest from each other contact the outer wall of the transformer 112's heat sink. The rectangular support plates 213 are made of thermally conductive material, and the cleaning blocks 214 are made of fluororubber, which is heat-resistant, elastic, and has moderate friction, making it less likely to scratch the heat sink. The latching components... Component 22 includes a support base 221 fixedly connected to the top of the top plate 113. An elastic open clamp 222 is fixedly connected to the front side of the support base 221. A connector is provided on the rear side of the rectangular rod 215. The connector includes a ball joint 223 fixedly connected to the rear side of the rectangular rod 215. The ball joint 223 is adapted to the elastic open clamp 222. Specifically, under the action of external force, the ball head squeezes the arc-shaped elastic arms on both sides of the clamp, and the elastic arms elastically open outward. After the ball head is fully embedded in the inner ring of the clamp, the elastic arms rebound and close by their own material. The arc-shaped inner wall wraps the spherical surface of the ball head and holds the ball by the elastic pre-tightening force to achieve limit locking. By setting the cleaning part 2, dust and impurities accumulated on the surface of the heat sink can be removed, avoiding dust accumulation from hindering heat dissipation, ensuring the heat dissipation efficiency of the high impedance transformer, maintaining stable operation of the equipment, reducing operating energy consumption, and quickly completing the positioning and locking of the cleaning component after cleaning.

[0019] The retractable handle portion 3 includes a telescopic component 31, which is mounted on a rectangular rod 215; and a limiting component 32, which is mounted on a fixed block 211. The telescopic component 31 includes a cylindrical rod 311 hinged to the front side of the rectangular rod 215, on which a handle 312 is provided. A cylindrical groove 313 is provided on the rear side of the handle 312. The cylindrical rod 311 is slidably connected to the handle 312 through the cylindrical groove 313. The limiting component 32 includes an elastic block 321 fixedly connected to the front side of the rectangular rod 215. An arc groove 322 is provided on the elastic block 321, and a friction element is provided on the elastic block 321. 22 is adapted to handle 312. Elastic block 321 can limit and lock handle 312 through arc groove 322. Friction component includes friction block 323 fixedly connected to the inner wall of arc groove 322. The front side of elastic block 321 is provided with beveled chamfer 324. The front side of elastic block 321 is beveled to form beveled chamfer 324. By setting up handle part 3, handle 312 can be pulled out during cleaning to obtain appropriate operating torque, which is convenient for manual driving of the cleaning part to rotate. After cleaning, handle 312 can be retracted and locked to limit, avoiding the handle 312 from being bumped, accidentally touched, or swinging and damaged due to long-term extension, realizing the self-locking of handle 312.

[0020] The protective section 4 includes a U-shaped support block 411 fixedly connected to the top of the base plate 111. Two side protective plates 412 are fixedly connected to the top of the U-shaped support block 411, and a front protective plate 413 is fixedly connected between the two side protective plates 412. The bottom of the front protective plate 413 is fixedly connected to the top of the U-shaped support block 411. The two side protective plates 412 and the front protective plate 413 form an inverted protective bucket-shaped structure to prevent impurities from entering the hard-to-clean area below the transformer 112 during cleaning. By setting up the protective section 4, the falling dirt can be received and intercepted during the entire process of the cleaning section 2 scraping off the dust and impurities from the heat sink. This prevents dust and debris from falling into the dead corner between the bottom of the transformer and the base plate, and prevents impurities from accumulating in the hard-to-clean bottom area for a long time, causing corrosion and local heat accumulation. This reduces the hidden dangers at the bottom of the transformer from the source and reduces the difficulty of subsequent deep cleaning.

[0021] In use, in the initial state, the cleaning component 21 and the retractable handle 3 are in the retracted and locked state, and the cleaning block 214 is attached to the heat sink of the transformer 112. When cleaning the heat sink of transformer 112, manually pull handle 312 so that handle 312 slides outward along cylindrical groove 313 of cylindrical rod 311, disengaging from arc groove 322 and friction block 323, releasing the storage and locking state of handle 312, and simultaneously pulling handle 312 out of cylindrical rod 311. Then, by rotating the extended handle 312, the cylindrical rod 311 hinged to the front of the rectangular rod 215 swings synchronously, thereby causing the rectangular rod 215 to rotate around the pivot 212 between the two fixed blocks 211; the rectangular rod 215 causes all the rectangular support plates 213 on the outer wall of the pivot 212 to rotate synchronously, and the cleaning blocks 214 fixed on both sides of the rectangular support plates 213 scrape against the outer wall of the heat sink of the transformer 112 to remove dust and impurities from the surface of the heat sink; Throughout the cleaning process, the U-shaped support block 411 on the base plate 111, the two side protective plates 412, and the front protective plate 413 form an inverted protective bucket structure to intercept the impurities that fall off during cleaning and prevent impurities from falling into the sealed dead corner area between the bottom of the transformer 112 and the base plate 111. After cleaning, the handle 312 drives the rectangular rod 215, rectangular support plate 213, and cleaning block 214 to rotate back to their initial positions. The ball joint 223 on the rear side of the rectangular rod 215 presses the elastic opening clamp 222 connected to the support seat 221 on the top plate 113, forcing the elastic arms on both sides of the elastic opening clamp 222 to open outward. After the ball joint 223 is fully embedded in the clamp, the elastic arms spring back and close, hugging the spherical surface of the ball joint 223. The ball joint 223 is locked by the elastic pre-tightening force, fixing the position of the overall cleaning assembly 21. Press the handle 312 inward to retract the cylindrical rod 311 into the cylindrical groove 313 of the handle 312; then rotate the handle 312 close to the elastic block 321, the handle 312 slides along the chamfered edge 324 of the elastic block 321 and presses the elastic block 321 upward to cause a slight deformation; when the handle 312 falls completely into the arc groove 322, the elastic block 321 rebounds and resets, and the friction block 323 on the inner wall of the arc groove 322 tightly adheres to the outer wall of the handle 312, relying on friction to lock the handle 312, preventing the handle 312 from accidentally sliding or popping out, and completing the overall retraction and reset.
