Description

Technical Field

[0001] The invention relates to the technical field of transformer installation, and in particular to an adjustable transformer based on a quick installation structure. Background Art

[0002] With the rapid development of the power industry and the continuous expansion of the power grid, the performance and installation efficiency of on-load tap-changing oil-immersed transformers, as important voltage regulation equipment in the power system, directly affect the stable operation and economic benefits of the power system. However, in current power practice, traditional on-load tap-changing oil-immersed transformers face many challenges and shortcomings in terms of rapid installation structure.

[0003] First, low installation efficiency is a common problem of on-load tap-changing oil-immersed transformers. Due to the complex structure and numerous components of the transformer, the installation process often requires multiple steps, and some operations require highly specialized skills and tools, which not only increases the installation time, but also increases the technical requirements for installers. In addition, the cumbersome steps and complex connections during the installation process can easily lead to installation errors, affecting the normal operation of the transformer.

[0004] Secondly, the instability of installation quality is also an urgent problem to be solved. During the installation of the transformer, due to factors such as vibration, temperature changes or improper operation, the connection between the transformer components may be loose or loose, which in turn affects the stability and safety of the transformer.

[0013] The beneficial effects of the adjustable transformer based on the quick installation structure of the present invention are as follows:

[0014] 1. The installation steps of the transformer are greatly simplified by designing a clever quick installation structure, especially the automatic docking and locking mechanism in the docking assembly. The support rod at the bottom of the transformer can automatically adjust its position through curved surface extrusion between the connecting rod assembly and the docking assembly, ensuring that the connector is smoothly inserted into the docking hole, achieving fast and accurate docking. This design not only reduces the difficulty of installation, but also significantly shortens the installation time and improves the overall installation efficiency.

[0015] 2. During the installation process, the pressure of the transformer falling is transmitted to the docking assembly through the connecting rod assembly, thereby triggering the locking mechanism of block 1 and block 2. Block 1 tightly clamps the connector under the action of spring 1, while block 2 is inserted into bayonet 1 under the push of spring 3, achieving double locking, effectively preventing the loose connection caused by vibration, temperature changes and other factors, and significantly improving the stability of installation quality.

[0016] 3. The docking mechanism has the function of automatically adjusting the position. Even if the initial position of the connector and the docking hole is not completely aligned, it can automatically adjust to the correct position through curved surface extrusion, thus achieving fault tolerance during the installation process. This design greatly reduces the risk of installation failure caused by slight deviation of the installation position and improves the reliability and success rate of installation.

[0017] 4. The installation mechanism is designed with a dust cover, which effectively blocks the gap between the base and the installation plate, reduces the entry of dust and other impurities, and is conducive to the long-term stable operation of the transformer. In addition, the leaf spring and pulley design in the installation mechanism effectively buffer the impact force during the installation of the transformer, protecting the transformer and the installation mechanism from damage. At the same time, the combined structure of the support block and the slide bar enables the installation plate to be flexibly adjusted as needed, enhancing the stability and safety of the overall structure.

The curved squeezing force of the two will cause the docking seat 2211 to drive the docking assembly 22 and the mounting plate 213 to move, so that it moves with the squeezing until the connecting head 235 can be inserted into the docking hole 22111. The docking is achieved by adjusting the position by squeezing, which greatly improves the fault tolerance of the installation.

[0051] After the connector 235 is inserted into the docking hole 22111, the transformer body 1 continues to fall until the connector 235 falls to the bottom of the docking hole 22111, and then the support rod 11 falls again to contact the pressing frame 2213. As the support rod 11 falls, the pressing frame 2213 is pressed down. The pressing frame 2213 presses the pressing surface 1 22121 of the block 1 2212 through the pressing surface 22131. By squeezing, one end of the block 1 2212 moves toward the inside of the docking hole 22111. As the support rod 11 falls onto the fixing seat 221, the block 1 The first end 2212 will clamp the connector 235 inside the docking hole 22111, and when the top of the pressing frame 2213 is pressed down and is level with the top of the fixing seat 221, the first bayonet 22133 will be level with the second bayonet 2216. When they are level, the spring 3 2226 inside the sliding groove 3 2222 will push one end of the second clamping block 2225 into the first bayonet 22133, and the pressing frame 2213 will be clamped so that the first clamping block 2212 can no longer move, thereby locking the connector 235, thereby realizing the rapid installation of the transformer body 1;

[0052] The mounting plate 213 will move in the direction of being squeezed. When the mounting plate 213 is squeezed, the force is transmitted to the leaf spring 217 through the support block 214, the slide bar 215, and the slider 216 for buffering. At the same time, the movement of the mounting plate 213 will move synchronously with the support block 214. For example, when the support block 214 moves left and right, it will drive the longitudinally arranged slide bar 215 to move along the transversely arranged slide bar 215, and vice versa for the longitudinal movement. The slide bar 215 will move with the support block 214. When the transformer body 1 drives the support rod 11 to fall to the top of the fixed seat 221, it will press the bottom of the support block 214 to contact the ground, thereby forming an effective support. The transformer will vibrate due to magnetostriction, electromagnetic force, mechanical stress and structural problems, load changes, short circuit faults and other problems. These vibrations are usually relatively mild and may affect the normal operation of the transformer, such as generating noise, accelerating insulation aging, and even causing mechanical failures. Therefore, a damping spring 236 is preferably provided between the connecting bolt 234 and the movable cavity 232 to reduce vibration, and at the same time, it also plays a supporting role. The damping spring 236 is continuously compressed during the falling process of the transformer body 1, and is compressed until a constant value is reached between the damping spring 236 and the transformer body 1, thereby achieving a damping of slight vibration by the damping spring 236.

[0053] When the transformer body 1 needs to be removed from the mounting mechanism 2, first, the output end of the telescopic rod 2227 pushes the push rod 2223 to drive the extrusion block 2224 to move toward the movable block 2225. When the extrusion block 2224 moves to the inside of the docking interface 22251 of the block 2225, the extrusion block 2224 will squeeze the inclined surface in the docking interface 22251 through the inclined surface, so that the block 2225 moves out of the bayonet 1 22133. Then, the transformer body 1 is driven upward by the lifting mechanism, and the connecting bolt 234 can move a short distance inside the movable cavity 232. Therefore, the upward movement of the transformer body 1 will first drive the support rod 11 to leave the fixed seat 221, and at the same time the pressure frame 2213 loses pressure, and the spring 22134 pushes the pressure frame 2213 to reset. The reset of the pressure frame 2213 causes the block 1 2212 to lose its extrusion, and then the spring 1 22122 will push the block 1 2212 to reset. At this time, as the transformer body 1 continues to move upward, the connecting bolt 234 and the connecting head 235 will be pulled out of the docking hole 22111, and then the plug 231 will be pulled out of the mounting slot 12 of the support rod 11, and the removal of the transformer body 1 can be completed.

[0054] By designing a quick installation mechanism 2, especially the automatic docking and locking mechanism of the docking assembly 22, the installation of the transformer body 1 is simplified. The connecting rod assembly 23 and the docking assembly 22 automatically adjust their positions, quickly dock, reduce technical requirements, and shorten installation time. The falling pressure triggers the locking of block 1 2212 and block 2 2225, which doubles the protection against loosening and improves the installation quality. The docking mechanism automatically adjusts its position, has strong fault tolerance, and reduces the risk of installation failure. The installation mechanism 2 is equipped with a dust cover 218 to prevent dust and dust, facilitate quick disassembly and installation, and is easy to maintain. Buffer elements such as leaf springs 217 protect the transformer body 1 from installation impact.
