A stable connecting plate is fixedly installed at the bottom of the rubber shock-absorbing pad, and a supporting base plate is provided below the stable connecting plate. Both sides of the front and back of the supporting base plate are fixedly installed with fixing plates, and connecting screw holes are vertically provided on the fixing plates. The bottom of the stable connecting plate and the top of the supporting base plate are fixedly installed with evenly distributed connecting sockets. The dry-type transformer with high stability can reduce the impact of vibration on the dry-type transformer to a lower level, more effectively improve the stability of the dry-type transformer, and make the safety factor of the dry-type transformer higher and the failure rate lower when in use.

It can be seen that most dry-type transformers are connected by bolts during installation to fix the bottom of the dry-type transformer, which will also increase the shock absorption effect of the dry-type transformer installation structure. However, the installation structure is complicated and the internal parts are prone to damage. In addition, the shock-absorbing structure is also used to fix the lower position of the dry-type transformer, which reduces the high stability of the installation and the flexibility of the dry-type transformer installation structure, thereby reducing the service life of the dry-type transformer installation structure.

In view of this, we propose a high-stability dry-type transformer.

DETAILED DESCRIPTION

Most dry-type transformers are connected by bolts during installation to fix the bottom of the dry-type transformer, which will also increase the shock absorption effect of the dry-type transformer installation structure. However, the installation structure is complicated, and the internal parts are prone to damage. In addition, the shock absorption structure also fixes the bottom of the dry-type transformer, which reduces the high stability of the installation and the flexibility of the dry-type transformer installation structure, thereby reducing the service life of the dry-type transformer installation structure.

Please refer to the embodiment of the utility model shown in Figures 1 to 4. The device includes a box body 10 and a dry-type transformer body 30. A connecting frame 31 is provided on both sides of the bottom and top of the dry-type transformer body 30. Two mounting components 20 for mounting the dry-type transformer body 30 are provided at the bottom of the box body 10. A fixing component 11 for reinforcing the installation of the mounting component 20 is provided at the top of the box body 10; the mounting component 20 includes at least two clamping components 22 and a shock absorbing component 21. The shock absorbing component 21 is located between the two clamping components 22. The two clamping components 22 are used to clamp the connecting frame 31. The clamping component 22 located below the shock absorbing component 21 is fixedly connected to the inner wall of the box body 10. The shock absorbing component 21 is used to increase the stability of the dry-type transformer body 30 during use.

First, the specific structure of the fixing assembly 11 is disclosed. The fixing assembly 11 at least includes a hydraulic cylinder 111 . The upper wall inside the box body 10 is provided with the hydraulic cylinder 111 , and the piston rod of the hydraulic cylinder 111 is provided with a fixing plate 112 .

The improvement lies in: connecting the hydraulic cylinder 111 to a power source to make it work, and moving the fixed plate 112 downward through the pushing work of the piston rod of the hydraulic cylinder 111. At the same time, the position of the mounting assembly 20 is reinforced to increase the stability of the installation of the dry-type transformer body 30, thereby improving the safety of the use of the dry-type transformer.

Secondly, the specific structure of the shock absorbing assembly 21 is disclosed. The shock absorbing assembly 21 at least includes a support column 211, and the support column 211 is slidably connected to the inside of the adjusting column 212. The support column 211 and the adjusting column 212 are both provided with a limiting shaft 213. The support column 211 is provided with a shock absorbing spring 214, and the other end of the shock absorbing spring 214 is fixedly connected to the inside of the adjusting column 212, and the limiting shaft 213 is located inside the shock absorbing spring 214.

The improvement is that when the dry-type transformer body 30 is working, vibration may be generated. At this time, by installing the clamping components 22 at both ends of the shock-absorbing component 21, the adjustment column 212 slides inside the support column 211. At the same time, the shock-absorbing spring 214 is deformed to reduce the amplitude of the vibration of the dry-type transformer body 30, thereby improving the installation stability of the dry-type transformer body 30. The working principle of the above-mentioned shock-absorbing component 21 is similar to the working principle of the damper, which plays a shock-absorbing role on the dry-type transformer body 30.

The specific structure of the clamping assembly 22 is disclosed again. The clamping assembly 22 at least includes a base plate 221. The base plate 221 is arranged at the bottom of the support column 211, and a clamping plate 224 is arranged at the top of the adjusting column 212. Mounting blocks 222 are arranged on both sides of the base plate 221 at the bottom of the support column 211 and on one side of the clamping plate 224 at the top of the adjusting column 212. A cylinder 223 is arranged inside the mounting block 222, and the piston rod of the cylinder 223 close to the adjusting column 212 is fixedly connected to the base plate 221, and the piston rod of the cylinder 223 close to the bottom of the support column 211 is fixedly connected to the clamping plate 224, and a pad 225 is arranged on the side of the base plate 221 close to the connecting frame 31.

The improvement lies in that: the cylinder 223 is powered on to make it work, and the shock absorbing assembly 21 is moved upward by the pushing work of the piston rod of the cylinder 223, and the bottom plate 221 located above the shock absorbing assembly 21 is also pushed upward. At this time, the dry-type transformer body 30 can be installed, and the connecting frame 31 is inserted into the surface of the pad 225. The connecting frame 31 is clamped by the resetting work of the piston rod of the cylinder 223. Not only is the operation simple, but the upper and lower sides of the dry-type transformer body 30 are clamped, which improves the stability of the installation of the dry-type transformer body 30, thereby improving the safety of the use of the dry-type transformer installation structure.

Considering that the pad 225 may slide or become loose inside the connecting frame 31, which reduces the stability of the installation of the dry-type transformer body 30, an anti-skid pad 23 for increasing friction is provided on the surface of the pad 225, and the anti-skid pad 23 has a certain elasticity.

The improvement lies in that when the clamping assembly 22 clamps the connecting frame 31, the anti-slip pad 23 is deformed and contracted, and at the same time, the friction between the anti-slip pad 23 and the inner wall of the connecting frame 31 is increased, thereby increasing resistance and preventing sliding or loosening, thereby improving the stability of the installation of the dry-type transformer body 30 and improving the practicality of the dry-type transformer installation structure.

In summary, the working principle of the present solution is as follows: first, the cylinder 223 is powered on to make it work, and the shock absorbing assembly 21 is moved upward by the pushing work of the piston rod of the cylinder 223, and the bottom plate 221 located above the shock absorbing assembly 21 is also pushed upward. At this time, the dry-type transformer body 30 can be installed, and the connecting frame 31 is inserted into the surface of the pad 225. The connecting frame 31 is clamped by the resetting work of the piston rod of the cylinder 223. After that, the hydraulic cylinder 111 is powered on to make it work, and the fixing plate 112 is moved downward by the pushing work of the piston rod of the hydraulic cylinder 111. At the same time, the position of the mounting assembly 20 is reinforced, and the installation of the dry-type transformer can be completed.
