[0002] The iron core is the primary magnetic circuit component of a transformer. It's typically constructed from stacked hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with an insulating varnish. The iron core and the coils wound around it form a complete electromagnetic induction system. The power a power transformer can transmit depends on the material and cross-sectional area of ​​the iron core. Current transformer cores are typically fabricated by stacking silicon steel sheets on top of an iron core. However, these cores are typically monolithic and can only accommodate transformer designs of a single size, which is insufficient for current applications.

[0003] As disclosed in Chinese patent CN207503785U, an adjustable high-stability transformer core comprises an upper iron yoke and a lower iron yoke, the upper iron yoke and the lower iron yoke are composed of a connecting block, a movable connecting plate and an intermediate connecting block, and the adjacent sides of the connecting block are provided with vertically arranged connecting grooves and edge core column connecting grooves, the intermediate connecting block is a T-shaped block, the horizontal ends of the intermediate connecting block are fixedly connected to the movable connecting plate, the two ends of the movable connecting plate are provided with a limited slide, the limited slide is connected and movably provided with a slide, the slide body is provided with multiple rows of through holes, the front end of the slide is provided with a connecting hole, and the vertical end of the intermediate connecting block is provided with an intermediate core column connecting groove. The utility model is novel in structure, stable, easy to assemble and easy to transport, and the assembly of cores of different specifications can be achieved through the adjustable design of the movable connecting plate.

[0004] However, during use, the adjustable high-stability transformer core is not convenient for pushing and sliding the transformer core, adjusting its position, and realizing its installation operation. Moreover, there is no structure for limiting and fixing the transformer core after installation, resulting in insufficient installation stability and low adjustability.

[0005] Therefore, a multi-stage adjustable transformer core structure is proposed to solve the above problems. Utility Model Content

[0013] Furthermore, one end of the fixing column passes through the No. 1 circular hole and is connected to the output end of the hydraulic cylinder, and the surface of one end of the fixing column is fixedly connected to one side of the outer surface of the sliding plate.

[0014] Furthermore, the compression springs are symmetrically distributed at both ends of one side of the outer surface of the connecting plate, and the bidirectional cylinders are symmetrically distributed at both sides of the upper surface of the fixing seat.

[0027] like Figure 1-4 As shown, a multi-stage adjustable transformer core structure includes a fixing base 1 and a square slot 201. The square slot 201 runs through the upper surface of the fixing base 1. A sliding component 2 is arranged inside the square slot 201. A limiting component 3 is arranged on the upper surface of the fixing base 1. The square slot 201 runs through the upper surface of the fixing base 1. The sliding component 2 arranged inside the square slot 201 slides the transformer core to adjust the placement position of the transformer core. Cooperating with the limiting component 3, the limiting component 3 is used to limit the position of the transformer core after sliding and moving, and at the same time complete the clamping and fixation of the transformer core.

[0028] The sliding assembly 2 includes a No. 1 circular hole 202 that passes through one side of the outer surface of the fixed base 1, a hydraulic cylinder 203 is fixedly connected to one side of the outer surface of the fixed base 1, the output end of the hydraulic cylinder 203 is connected to a fixed column 204, a slide groove 208 is passed through one side of the outer surface of the fixed base 1, a fixed round rod 205 is fixedly installed on the inner wall of the slide groove 208, the outer surface of the fixed round rod 205 is slidably connected to a sliding plate 206, and a No. 2 circular hole 207 is passed through one side of the outer surface of the sliding plate 206; when the hydraulic cylinder 203 is operated, the output end of the hydraulic cylinder 203 pushes the fixed column 204 to move to a position away from the hydraulic cylinder 203, or moves to a position close to the hydraulic cylinder 203, and the fixed column 204 drives the sliding plate 206 to move. When the sliding plate 206 moves, its two sides slide on the outer surface of the fixed round rod 205, and the fixed round rod 205 provides support and stability for the sliding plate 206 when it moves.

[0029] The limiting component 3 includes a two-way cylinder 301 fixedly connected to the upper surface of the fixing seat 1, and the output ends on both sides of the two-way cylinder 301 are connected to push rods 302, and one end surface of the push rod 302 is fixedly connected to a connecting plate 303, and a compression spring 304 is fixedly connected to the middle position of one side of the outer surface of the connecting plate 303, and one end of the compression spring 304 is fixedly connected to the limiting plate 305; after the transformer core is moved, the two-way cylinder 301 in the limiting component 3 is operated, and the output ends on both sides of the two-way cylinder 301 simultaneously push the push rod 302 to move outward, and the push rods 302 at both ends of the two-way cylinder 301 respectively drive the connecting plate 303 to move outward. When the connecting plate 303 moves and the push rods 302 on both sides move a distance greater than the length of the transformer core, the bidirectional cylinder 301 is operated so that the bidirectional cylinder 301 drives the push rod 302 to retract and the push rod 302 drives the connecting plate 303 to move closer to the bidirectional cylinder 301. The limit plate 305 connected to the compression spring 304 fixedly connected to the side of the connecting plate 303 continues to move when one side of its outer surface contacts the iron core 401. When the compression spring 304 is compressed to half of its own length, the push rod 302 stops moving. At this time, the limit plate 305 clamps and fixes the iron core 401.

[0030] An iron core column 4 is installed in the middle position of the upper surface of the sliding plate 206, and an iron core sheet 401 is stacked on the outer surface of the iron core column 4. A fixing rod 402 is fixedly connected to the upper surface of the sliding plate 206, and a top plate 403 is fixedly connected to the top surface of the fixing rod 402. After the iron core sheet 401 is stacked on the outer surface of the iron core column 4, the fixing rod 402 is fixedly connected to the upper surface of the sliding plate 206 to limit the two sides of the outer surface of the iron core sheet 401, and at the same time, the top plate 403 fixedly connected to the upper surface of the fixing rod 402 limits the upper part of the iron core column 4.

[0031] The slide grooves 208 are symmetrically distributed on both sides of the outer surface of the fixed seat 1. The sliding plate 206 is connected to the outer surface of the fixed round rod 205 through the No. 2 circular hole 207, and the fixed round rod 205 passes through the No. 2 circular hole 207 and is connected to the sliding plate 206; the fixed round rod 205 is fixedly installed on the inner wall of the slide groove 208, and the fixed round rod 205 passes through the No. 2 circular hole 207 and is slidably connected to the sliding plate 206. The sliding plate 206 slides on the outer surface of the fixed round rod 205 when moving.

[0032] One end of the fixed column 204 passes through the No. 1 circular hole 202 and is connected to the output end of the hydraulic cylinder 203, and the surface of one end of the fixed column 204 is fixedly connected to one side of the outer surface of the sliding plate 206; when the output end of the hydraulic cylinder 203 pushes the fixed column 204 to move, the fixed column 204 passes through the No. 1 circular hole 202 and is connected to the output end of the hydraulic cylinder 203, so the fixed column 204 passes through the No. 1 circular hole 202 to push the sliding plate 206 to move.

[0033] The compression springs 304 are symmetrically distributed at both ends of one side of the outer surface of the connecting plate 303, and the bidirectional cylinders 301 are symmetrically distributed on both sides of the upper surface of the fixing base 1; the bidirectional cylinders 301 are distributed on both sides of the upper surface of the fixing base 1, and can simultaneously push the push rods 302 at the output ends on both sides. The four push rods 302 on the upper surface of the fixing base 1 move at the same time and respectively drive the connecting plates 303 on both sides to move.

[0034] In summary, in the multi-stage adjustable transformer core structure, when adjusting the position of the transformer core, the core column 4 and the core sheet 401 stacked on the outer surface of the core column 4 are first installed on the upper surface of the sliding plate 206, and the core column 4 and the core sheet 401 installed on the sliding plate 206 are limited and fixed by the fixing rod 402 and the top plate 403. The hydraulic cylinder 203 is operated, and the output end of the hydraulic cylinder 203 pushes the fixed column 204 to move, and the fixed column 204 drives the sliding plate 206 to move. At the same time, the sliding plate 206 is moved. 06 slides on the outer surface of the fixed round rod 205, adjusts the position of the sliding plate 206, and operates the two-way cylinder 301. The output ends on both sides of the two-way cylinder 301 push the push rod 302 to move, and the push rod 302 drives the connecting plate 303 to move. When the connecting plate 303 moves, one side of the outer surface of the limit plate 305 contacts the iron chip 401 and continues to move. When the compression spring 304 is compressed to half of its own length, the push rod 302 stops moving. At this time, the limit plate 305 clamps and fixes the iron chip 401.
