Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more specifically to a transformer with quickly replaceable windings. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Transformers can be divided into power transformers and special transformers according to their uses. Power transformers are mainly used in power transmission and distribution lines to change the magnitude of AC voltage to meet the needs of different users. Special transformers are used in special fields such as metallurgy, electrical processing, electric drive, communication, and automatic control. Their main components are primary coil, secondary coil, and iron core.

[0003] The shortcomings of existing technology: Transformers inevitably suffer damage and burnout during long-term use, requiring maintenance and replacement of the transformer windings. However, existing transformer windings are installed between the iron cores, and replacing the windings requires disassembling the steel frame and iron cores, disassembling the entire transformer to remove the windings. This is also quite troublesome during subsequent installation. Therefore, we propose a transformer with quick winding replacement. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transformer with quick winding replacement to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: a transformer with quick-change windings, comprising a base, a first clamping steel frame and a support frame installed on the upper end of the base, a telescopic frame installed inside the support frame, a second clamping steel frame installed on the surface of the telescopic frame, a core frame installed inside the first and second clamping steel frames, the core frame comprising an upper horizontal frame, a middle vertical frame and a lower horizontal frame, the upper horizontal frame, the middle vertical frame and the lower horizontal frame being sequentially fitted together, a transformer winding installed inside the core frame, a quick-release assembly installed at the lower end of the first clamping steel frame, the quick-release assembly comprising a mounting seat, a sliding rod, a sliding base and a rotating base, multiple mounting seats installed at the lower end of the second clamping steel frame, multiple sets of sliding rods installed inside the mounting seats, lifting blocks installed at the lower end of each sliding rod, multiple sliding bases slidably connected to the circumferential surface of the sliding rod, multiple rotating bases rotatably connected between the sliding bases, and the rotating base and the middle vertical frame being fixedly connected by a positioning pin;

[0006] Preferably, the support frame has a sliding groove on its surface, the threaded seat fixedly connected between the telescopic frames is slidably connected to the sliding groove, and a pair of threaded rods are installed between the base and the support frame, the threaded rods being threadedly connected to the threaded seat.

[0007] Preferably, a drive rod is rotatably connected inside the base, and multiple first bevel gears are mounted on the circumferential surface of the drive rod. The second bevel gears mounted on the lower end of the threaded rod all mesh with the first bevel gears.

[0008] Preferably, a pair of first limiting plates are installed on the upper end of the first clamping steel frame, and the first limiting plates are in contact with the upper end of the lower cross frame.

[0009] Preferably, a support plate is fixedly connected to the circumferential surface of the slide rod, and a limit frame and a locking frame are rotatably connected to the circumferential surface of the slide rod. A locking groove is provided at the upper end of the limit frame, and the end of the locking frame away from the slide rod is located in the locking groove. Both the support plate and the locking frame are slidably connected to the transformer winding.

[0010] Preferably, a support block and a limiting block are installed on the circumferential surface of the slide rod, the limiting frame and the locking frame are slidably connected to the limiting block, and a spring is installed between the support block and the locking frame.

[0011] Preferably, each of the slide surfaces is equipped with a limiting post, which is slidably connected to an arc-shaped groove on the surface of the rotating seat. The limiting post is used to limit the rotation angle of the rotating seat.

[0012] Preferably, a pair of second limiting plates are installed on the upper end of the second steel clamping frame, and the second limiting plates are in contact with the upper end of the upper cross frame.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. This invention controls the telescopic frame to move upward within the support frame, driving the second clamping steel frame to move upward, causing the upper horizontal frame and sliding rod to move upward synchronously. At this time, multiple middle vertical frames and transformer windings are separated from the rising upper horizontal frame under the action of gravity. Subsequently, the lifting block drives the sliding seat to move upward, and the sliding seat drives the rotating seat to move upward. The rotating seat then synchronously drives the middle vertical frames and transformer windings to move upward, causing the middle vertical frames to separate from the lower horizontal frame. At this time, the middle vertical frames are separated from the upper and lower horizontal frames. Then, the rotating seat at the corresponding position is rotated, causing the middle vertical frame and transformer winding at the corresponding position to rotate. The transformer winding that needs to be replaced can be pulled out from the middle vertical frame. After the transformer winding is disassembled and replaced, the transformer winding is pushed upward to rotate, causing the rotating seat and middle vertical frame to rotate and reset. At this time, the first clamping steel frame is controlled to descend and reset, so that the upper horizontal frame, multiple middle vertical frames and lower horizontal frame are reconnected together, thereby achieving the effect of rapid replacement of transformer windings and improving the efficiency of transformer winding replacement and maintenance.

[0015] 2. This invention uses a support plate to restrict the rear position of the transformer winding, and a locking frame and a limiting frame to restrict the front position of the transformer winding, preventing the transformer winding from rotating and tilting simultaneously. The locking frame is controlled to move upward, so that one end of it is pulled out of the locking groove on the limiting frame. At this time, the transformer winding at the corresponding position can be controlled to rotate. Then, the transformer winding can be pulled out from the middle vertical frame to complete the replacement of the transformer winding. Then, the transformer winding is pushed to rotate and reset, and the limiting frame is rotated to fit against the surface of the transformer winding. At this time, the locking frame is inserted into the locking groove on the limiting frame to correct and position the transformer winding, so that the middle vertical frame and the transformer winding are perpendicular to the upper and lower horizontal frames. When the second clamping steel frame is lowered, the middle vertical frame can be reconnected to the upper and lower horizontal frames. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The transformer with quick-change windings involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, in one embodiment, a transformer with quick-change windings is proposed, including a base 1. A first clamping steel frame 101 and a support frame 102 are installed on the upper end of the base 1. A telescopic frame 103 is installed inside the support frame 102. A second clamping steel frame 104 is installed on the surface of the telescopic frame 103. A core frame 2 is installed inside the first clamping steel frame 101 and the second clamping steel frame 104. The core frame 2 includes an upper horizontal frame 201, a middle vertical frame 202, and a lower horizontal frame 203. The upper horizontal frame 201, multiple middle vertical frames 202, and lower horizontal frame 203 are sequentially attached and connected. A transformer is installed inside the core frame 2. The winding 3 has a quick-release assembly 4 installed at the lower end of the first clamping steel frame 101. The quick-release assembly 4 includes a mounting base 401, a sliding rod 402, a sliding seat 404, and a rotating seat 405. Multiple mounting bases 401 are installed at the lower end of the second clamping steel frame 104. Multiple sets of sliding rods 402 are installed inside the mounting bases 401. Each sliding rod 402 has a lifting block 403 installed at its lower end. Multiple sliding seats 404 are slidably connected to the circumferential surface of the sliding rod 402. Multiple rotating seats 405 are rotatably connected between the sliding seats 404. The rotating seats 405 are fixedly connected to the central vertical frame 202 by a positioning pin 406.

[0030] In practical application, when it is necessary to replace the transformer winding 3, the telescopic frame 103 is controlled to move upward within the support frame 102, driving the second clamping steel frame 104 to move upward. As the second clamping steel frame 104 moves upward, it drives the upper horizontal frame 201 and the sliding rod 402 to move upward synchronously. At this time, the multiple middle vertical frames 202 and the transformer winding 3, under the influence of gravity, separate from the rising upper horizontal frame 201. Subsequently, when the lifting block 403 installed at the lower end of the sliding rod 402 contacts the sliding seat 404, the lifting block 403 drives the sliding seat 404 to move upward. The sliding seat 404 drives the rotating seat 405 to move upward. Since the rotating seat 405 is fixed to the middle vertical frame 202 by the positioning pin 406, and the lower end of the transformer winding 3 is supported on the upper end of the rotating seat 405, the rotating seat 405 will synchronously drive the middle vertical frame 202 and the transformer winding 3 to move upward. As the second clamping steel frame 103 moves upward, the transformer winding 3 is replaced. The upward movement of slide bar 402 causes the middle vertical frame 202 to separate from the lower horizontal frame 203. At this time, the middle vertical frame 202 is separated from the upper horizontal frame 201 and the lower horizontal frame 203. The rotating seat 405 at the corresponding position of the transformer winding 3 to be replaced can be rotated to rotate the middle vertical frame 202 and the transformer winding 3 at the corresponding position, so that the transformer winding 3 to be replaced can be pulled out from the middle vertical frame 202. Then, the replaced transformer winding 3 is reinstalled on the middle vertical frame 202 at the corresponding position. Then, the transformer winding 3 is pushed upward to rotate the rotating seat 405 and the middle vertical frame 202 to rotate and reset. At this time, the first clamping steel frame 101 is controlled to descend and reset, so that the upper horizontal frame 201, multiple middle vertical frames 202 and lower horizontal frame 203 are reconnected together, thereby achieving the effect of quickly replacing the transformer winding 3 and improving the efficiency of transformer winding 3 replacement and maintenance.

[0031] like Figure 2 and 3 As shown, in one embodiment, a groove 5 is provided on the surface of the support frame 102, and the threaded seat 501 fixedly connected between the telescopic frames 103 is slidably connected to the groove 5. A pair of threaded rods 502 are installed between the base 1 and the support frame 102, and the threaded rods 502 are threadedly connected to the threaded seat 501.

[0032] In practical application, the present invention controls the simultaneous rotation of a pair of threaded rods 502, which in turn drives the threaded seat 501 to rise and fall. The threaded seat 501 then drives the telescopic frame 103 to rise and fall within the support frame 102, thereby achieving the effect of controlling the rise and fall of the second clamping steel frame 104. This enables the control of the separation and merging of the vertical frame 202 with the upper horizontal frame 201 and the lower horizontal frame 203, facilitating the replacement of the transformer winding 3 within them.

[0033] like Figure 2 and 3As shown, in one embodiment, a drive rod 503 is rotatably connected inside the base 1, and a plurality of first bevel gears 504 are mounted on the circumferential surface of the drive rod 503. The second bevel gears 505 mounted on the lower end of the threaded rod 502 all mesh with the first bevel gears 504.

[0034] In practical application, the drive rod 503 is controlled to rotate, which in turn drives multiple first bevel gears 504 to rotate. The first bevel gears 504 drive the corresponding second bevel gears 505 to rotate, which in turn drives multiple threaded rods 502 to rotate, thereby achieving the effect of controlling the telescopic frame 103 to rise and fall within the support frame 102. When replacing the transformer winding 3, the drive rod 503 is controlled to rotate forward, causing the second clamping steel frame 104 to rise, controlling the middle vertical frame 202 to separate from the lower horizontal frame 203 and the upper horizontal frame 201. After the winding is replaced, the drive rod 503 is controlled to rotate in reverse, causing the second steel frame to fall, causing the middle vertical frame 202 to merge with the lower horizontal frame 203 and the upper horizontal frame 201. At the same time, through the downward pressure of the second steel frame and the support of the base 1, the merged upper horizontal frame 201, middle vertical frame 202 and lower horizontal frame 203 can be tightly fitted together, completing the installation and fixation of the transformer winding 3 after replacement.

[0035] like Figure 2 and 8 As shown, in one embodiment, a pair of first limiting plates 6 are installed on the upper end of the first clamping steel frame 101, and the first limiting plates 6 are attached to the upper end of the lower crossbar 203.

[0036] In practical application, the first limiting plate 6 installed on the upper end of the lower horizontal frame 203 cooperates with the base 1 to restrict the vertical position of the lower horizontal frame 203, preventing the position of the lower horizontal frame 203 from moving when it is separated and merged with the middle vertical frame 202. This ensures that the position of the lower horizontal frame 203 remains unchanged when the transformer winding 3 is disassembled and replaced. When the middle vertical frame 202 is subsequently connected to the lower horizontal frame 203, it can be ensured that the connection is tight.

[0037] like Figure 3 and 4 As shown, in one embodiment, a support plate 7 is fixedly connected to the circumferential surface of the slide rod 402, and a limit frame 701 and a locking frame 702 are rotatably connected to the circumferential surface of the slide rod 402. A locking groove 703 is provided at the upper end of the limit frame 701, and the end of the locking frame 702 away from the slide rod 402 is located in the locking groove 703. Both the support plate 7 and the locking frame 702 are slidably connected to the transformer winding 3.

[0038] In practical application of this invention, after the middle vertical frame 202 separates sequentially from the upper horizontal frame 201 and the lower horizontal frame 203, the rear position of the transformer winding 3 is restricted by the support plate 7, and the front position of the transformer winding 3 is restricted by the locking frame 702 and the limiting frame 701, preventing the transformer winding 3 from rotating and tilting simultaneously. When it is necessary to replace one of the transformer windings 3, the locking frame 702 at the corresponding position is controlled to move upward, so that one end of it is pulled out from the locking groove 703 opened on the limiting frame 701. At this time, the transformer winding 3 at the corresponding position can be controlled to rotate, and then the transformer winding 3 can be removed from the middle horizontal frame. The transformer winding 3 is replaced by pulling out the vertical frame 202. After the transformer winding 3 is installed on the middle vertical frame 202, the transformer winding 3 is rotated to reset. Then, the limiting frame 701 is rotated to fit against the surface of the transformer winding 3. The locking frame 702 is then rotated to insert into the locking groove 703 on the limiting frame 701. In cooperation with the support plate 7, the position of the transformer winding 3 is corrected so that the middle vertical frame 202 and the transformer winding 3 are perpendicular to the upper horizontal frame 201 and the lower horizontal frame 203. When the second clamping steel frame 104 is lowered, the middle vertical frame 202 can be reconnected to the upper horizontal frame 201 and the lower horizontal frame 203.

[0039] like Figure 4 As shown, in one embodiment, a support block 704 and a limiting block 706 are mounted on the circumferential surface of the slide bar 402. The limiting frame 701 and the locking frame 702 are slidably connected to the limiting block 706. A spring 705 is installed between the support block 704 and the locking frame 702.

[0040] In practical application, the limiting block 706 restricts the position of the limiting frame 701 and the locking frame 702 on the slide rod 402, allowing them to rotate on the slide rod 402 at a specified position. The support block 704 and the spring 705 press down on the locking frame 702, so that one end of the locking frame 702 is stably inserted into the locking groove 703 opened on the limiting frame 701.

[0041] like Figure 5 and 6 As shown, in one embodiment, limit posts 8 are installed on the surface of the slide 404. The limit posts 8 are slidably connected to the arc grooves 801 opened on the surface of the rotating seat 405. The limit posts 8 are used to limit the rotation angle of the rotating seat 405.

[0042] In practical applications, when the rotating seat 405 controls the rotation of the central vertical frame 202 and the transformer winding 3, the rotation angle of the rotating seat 405 can be limited by the action of the limiting column 8, making it parallel to the ground. This makes it easier to assemble and disassemble the transformer winding 3 from the central vertical frame 202, thus improving the efficiency of assembling and disassembling the transformer winding 3.

[0043] like Figure 2 and 7As shown, in one embodiment, a pair of second limiting plates 9 are installed on the upper end of the second clamping steel frame 104, and the second limiting plates 9 are attached to the upper end of the upper cross frame 201.

[0044] In practical applications, the second limiting plate 9 and the mounting base 401 can restrict the position of the upper horizontal frame 201 in the second clamping steel frame 104. When the upper horizontal frame 201 and the middle vertical frame 202 are separated and merged, the position of the upper horizontal frame 201 in the second clamping steel frame 104 remains unchanged, ensuring the tightness of the upper horizontal frame 201 and the middle vertical frame 202 when they are separated and connected.

[0045] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
