Description

Technical Field

[0001] The utility model relates to the technical field of transformer internal shockproofing, in particular to a transformer internal shockproofing structure. Background Art

[0002] Transformers use the law of electromagnetic induction to achieve the function of stepping up or down voltage. The basic function of a transformer is to transform AC power. Its interior is mainly composed of a core body composed of an iron core and a coil winding. The iron core is where the magnetic circuit is located. The quality of the magnetic circuit is related to the transformer's no-load loss, excitation characteristics and noise quality. In order to ensure that the transformer can fully exert its performance and operate safely, in addition to installing various auxiliary equipment and conductors, the internal components of the transformer must also be properly installed in specific locations;

[0003] However, when the transformer is running, the iron core will be affected by the AC electromagnetic force and will undergo periodic magnetic flux changes. This change will cause vibration of the iron core, which will in turn generate noise and vibration in the transformer. In order to prevent the vibration from affecting the internal structure of the transformer for a long time, a shock-absorbing gasket will be set at the bottom of the coil to absorb energy and reduce vibration. The shock-absorbing gasket itself will be heavily worn after long-term use. However, it is difficult to remove the shock-absorbing gasket during subsequent replacement, which makes maintenance and replacement very troublesome and inconvenient for staff to operate.

[0004] In view of the above problems, the inventor proposes an internal shockproof structure of a transformer to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Figure 1-5 As shown, the utility model provides an internal shockproof structure of a transformer, comprising an upper bracket 1 and a lower bracket 11, an iron ring 12 is installed between the upper bracket 1 and the lower bracket 11, two symmetrically distributed bases 13 are fixedly provided on the lower surface of the lower bracket 11, and the bases 13 and the lower bracket 11 are arranged in a cross distribution, and a concave fixing seat 14 is provided directly below the base 13, and the bottom of the base 13 can be inserted into the concave surface of the fixing seat 14, and a shock-absorbing gasket 15 is installed on the concave surface of the fixing seat 14, and the upper surface of the shock-absorbing gasket 15 is against the bottom of the base 13, and screw rods 18 are rotatably provided at both ends of the fixing seat 14, and a movable plate 19 is threaded on the screw rod 18, and vertically arranged top rods 2 are fixed at the four corners of the upper surface of the movable plate 19, and L-shaped connecting plates 16 are fixedly provided at both ends of the base 13, and the tops of the four top rods 2 are fixedly provided on the upper surface of the connecting plate 16.

[0022] A groove 17 is provided inside the fixed seat 14, and a rotating rod 21 is provided inside the groove 17 near the bottom of the screw rod 18. The top of the rotating rod 21 is fixedly set at the bottom of the screw rod 18, and a first belt 22 is provided on the common transmission sleeve at the bottom of the two rotating rods 21. A connecting shaft 23 is provided on the common transmission sleeve between the two fixed seats 14, and the end of the connecting shaft 23 near the rotating rod 21 is connected by two meshing bevel gears 24.

[0023] By adopting the above technical solution, the four screw rods 18 in the two mounting frames can be driven to rotate simultaneously through the first belt 22 and the connecting shaft 23, thereby increasing the linkage of the device.

[0024] A transmission shaft 25 is rotatably provided on one side of the outer wall of one of the fixed seats 14 close to the connecting shaft 23. The transmission shaft 25 is connected to the connecting shaft 23 through a second belt 26. A driving motor 27 is installed on the outer wall of the fixed seat 14 close to the driving shaft 25. The output end of the driving motor 27 is coaxially fixed to the transmission shaft 25.

[0025] By adopting the above technical solution, when the drive motor 27 drives the transmission shaft 25 to rotate, the second belt 26 can drive the connecting shaft 23 to rotate. At this time, the connecting shaft 23 can drive the screw rod 18 to work through the meshing bevel gear 24, thereby improving the convenience of work.

[0026] An L-shaped support frame 28 is fixedly disposed on the outer wall of the fixing seat 14 near the connecting shaft 23 , and an end of the connecting shaft 23 passes through the support frame 28 .

[0027] By adopting the above technical solution, the support frame 28 is provided to provide support for the connecting shaft 23 when it rotates, thereby ensuring the stability of the connecting shaft 23 when it rotates, so that the connecting shaft 23 can rotate stably.

[0028] A vertically arranged limiting rod 3 is movably inserted into one end of the connecting plate 16 close to the base 13 , and the bottom of the limiting rod 3 is fixedly arranged on the upper surface of the fixing seat 14 .

[0029] By adopting the above technical solution, the limit rod 3 can support the connecting plate 16, thereby ensuring that the connecting plate 16 can stably move upward when pushed by the movable plate 19, avoiding offset between the connecting plate 16 and the base 13, resulting in instability in subsequent use.

[0030] A positioning hole 161 is defined at the bottom of the connecting plate 16 .

[0031] By adopting the above technical solution, a fixing bolt can be installed in the positioning hole 161 , and the connecting plate 16 can be installed on the inside of the shell through the fixing bolt to ensure the stability of the connecting plate 16 .

[0032] A U-shaped baffle plate 29 is fixedly disposed on one side of the two fixing seats 14 away from the supporting frame 28 . The baffle plate 29 can shield one end of the shock-absorbing gasket 15 .

[0033] By adopting the above technical solution, the baffle 29 can be set to connect one end of the shock-absorbing gasket 15, so that the staff can directly insert the shock-absorbing gasket 15 into the concave surface of the fixing seat 14 without adjusting and confirming the position.

[0034] Working principle: When in use, a shock-absorbing gasket 15 is arranged between the base 13 and the fixed seat 14, so that the shock-absorbing gasket 15 can absorb the vibration generated by the iron ring 12 to reduce its shock. At the same time, after working for a long time, when the shock-absorbing gasket 15 absorbs more energy and wears out more and needs to be replaced, the drive motor 27 can work. The drive motor 27 can simultaneously drive the rotating rods 21 in the two fixed seats 14 to drive the screw rods 18 to rotate synchronously through the second belt 26, the connecting shaft 23, the first belt 22 and the two meshing bevel gears 24. When the screw rod 18 rotates, it will drive the movable plate 19 with threads on itself to move upward. At this time, the top rods 2 set at the four corners of the upper surface of the movable plate 19 move up, and the top rods 2 will push the connecting plate 16 connected to the base 13 to move up, and the connecting plate 16 will drive the upper lower bracket 11 to move up through the base 13. At this time, the staff can directly pull the shock-absorbing gasket 15 in the fixed seat 14 to move it away from the fixed seat 14. The subsequent staff can put a new shock-absorbing gasket 15 into the fixed seat 14. At the same time, due to the limitation of the baffle 29, it can be directly inserted without adjusting and confirming the position. Through the above operation, the shock-absorbing gasket 15 used for shockproofing inside the transformer can be quickly replaced, and the overall operation is relatively convenient, which is convenient for maintenance personnel to operate.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
