Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an easily adjustable transformer winding set. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The iron core is an indispensable part of the transformer. The iron core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint on the surface. The iron core and the coil wound on it form a complete electromagnetic induction system. The function of the iron core is to strengthen the magnetic coupling between the two coils.

[0003] In daily production processes, the output voltage of the transformer needs to be adjusted. Generally, transformers are fixed-ratio transformers, and the transformation parameters are not adjustable. Utility Model Content

[0004] The purpose of the utility model is to provide an easily adjustable transformer winding group to address the defects of the prior art, so as to solve the problem that the output voltage of the transformer needs to be adjusted in the daily production process, and general transformers are fixed ratio transformers and the transformation parameters cannot be adjusted.

[0022] Example

[0023] Combination Figure 1-5As shown, an easily adjustable transformer winding group includes a base 1, the base 1 is provided with a guide groove 101 for inserting a guide block 402, the guide groove 101 and the guide block 402 are arranged to improve the connection strength between the winding group 4 and the base 1, the bottom end surface of the guide groove 101 is provided with a base threaded hole 102 for allowing the base threaded end 601 on the fastening rod 6 to pass through the first through groove 403 and the second through groove 503 and then be screwed, protective plates 2 are symmetrically arranged on both sides of the base 1, and a fixing plate 3 is arranged between the tops of the two protective plates 2, through the provision of the protective plate 2, the winding group 4 installed between the base 1 and the fixing plate 3 can be protected, and the fixing plate 3, the two protective plates 2 and the base 1 are an integrally formed structure, a plurality of winding groups 4 are arranged between the fixing plate 3 and the base 1, and the fixing plate 3 is penetrated with a fixing threaded hole 302 which is connected one by one with the second through groove 503 and can be screwed with the fixing threaded end 602.

[0024] Among them, a driving threaded hole 301 is penetrated through the fixing plate 3, and a driving threaded rod 504 is threaded in the driving threaded hole 301. Through the setting of the driving threaded rod 504 and the driving threaded hole 301, the driving plate 5 can be displaced up and down, so as to fix the top of the winding group 4. The bottom of the driving threaded rod 504 extends to be rotatably connected with the top end face of the driving plate 5, and the top of the driving threaded rod 504 extends to the outside of the driving threaded hole 301 and a handwheel 505 is provided. Through the setting of the handwheel 505, it is convenient for the staff to operate the driving threaded rod 504.

[0025] Among them, limiting holes 303 are penetrated on the fixing plate 3 on both sides of the driving threaded hole 301, and limiting rods 506 are slidably connected in the limiting holes 303. The bottom of the limiting rod 506 is fixedly connected to the top end face of the driving plate 5, and the top of the limiting rod 506 extends to the outside of the limiting hole 303 and is provided with a limiting plate 507. Through the setting of the limiting rod 506, the driving plate 5 is prevented from changing its angle when the driving threaded rod 504 drives the driving plate 5 to move up and down, thereby affecting the connection between the guide column 501 and the fastening block 502 and the guide groove 405 and the fastening groove 406.

[0026] like Figure 3 The winding group 4 shown in the figure has a lower mounting plate 401 at the bottom of the winding group 4, a guide block 402 with a trapezoidal structure is provided on one side of the bottom of the lower mounting plate 401, first through grooves 403 are symmetrically penetrated on both sides of the guide block 402, a fastening rod 6 is provided in the first through groove 403, an upper mounting plate 404 is provided on the top of the winding group 4, a guide groove 405 is provided on the top end surface of the upper mounting plate 404, fastening grooves 406 with a cross-shaped structure are provided on the top end surface of the upper mounting plate 404 on both sides of the guide groove 405, and a driving plate 5 is pressed on the top of the upper mounting plate 404.

[0027] like Figure 4 The driving plate 5 shown in the figure has a guiding column 501 on the bottom end surface of the driving plate 5 which can be inserted into the guiding groove 405, and the height of the guiding column 501 is greater than the height of the fastening block 502. The setting of the guiding column 501 provides a guide for the fastening groove 406 and the fastening block 502 to be inserted. The bottom end surfaces of the driving plate 5 on both sides of the guiding column 501 are provided with fastening blocks 502 that match the fastening groove 406. The setting of the fastening blocks 502 and the fastening groove 406 improves the stability of the driving plate 5 in fixing the winding group 4. The driving plate 5 is penetrated by a second through groove 503 corresponding to the first through groove 403, and the second through groove 503 is the same size as the first through groove 403.

[0028] like Figure 5 The fastening rod 6 shown has a base threaded end 601 at the bottom and a fixed threaded end 602 at the top. The fastening rod 6 is provided to improve the strength and stability of the winding group 4 installed between the base 1 and the fixed plate 3.

[0029] The working principle of the utility model is:

[0030] When it is necessary to adjust the winding group 4, the staff loosens the fastening rod 6 so that the base threaded end 601 and the fixed threaded end 602 are separated from the connection between the base threaded hole 102 and the fixed threaded hole 302, thereby removing the fastening rod 6, and then turns the hand wheel 505 to make the driving threaded rod 504 drive the driving plate 5 to move upward, and the driving plate 5 moves upward until the guide column 501 and the fastening block 502 are separated from the connection with the guide groove 405 and the fastening groove 406, and the winding group 4 is displaced toward the opening of the guide groove 101 so that the guide block 402 is separated from the guide groove 101, thereby removing the winding group 4 from the base 1, and replacing and adjusting the winding group 4. The utility model can disassemble the winding group 4, so as to facilitate the staff to adjust the output voltage of the transformer as needed, thereby greatly improving the applicability.

[0031] When the winding set 4 needs to be installed, first align the guide block 402 at the bottom of the winding set 4 with the guide groove 101 on the base 1 for plugging. When the guide block 402 and the guide groove 101 are plugged in, the first through groove 403 on the guide block 402 is connected with the base threaded hole 102 on the base 1, and the hand wheel 505 is turned to drive the driving plate 5 to move downward. The guide column 501 at the bottom of the driving plate 5 is first plugged into the guide groove 405 on the upper mounting plate 404, and the guide column 501 is inserted into the guide groove 405 on the upper mounting plate 404. During the continuous downward displacement process, the fastening block 502 is inserted into the fastening groove 406. At this time, the second through groove 503 on the driving plate 5 is connected with the first through groove 403. Then, the base threaded end 601 on the fastening rod 6 passes through the fixed threaded hole 302, the second through groove 503 and the first through groove 403 in sequence and is screwed into the base threaded hole 102 on the base 1. At the same time, the fixed threaded end 602 on the fastening rod 6 is screwed into the fixed threaded hole 302, thereby completing the installation of the winding group 4.
