Its unique double split winding structure, can effectively reduce the influence of the harmonic generated by rectifier device to power grid, improves electric energy quality, guarantees the efficient and stable operation of industrial production, however, with the continuous expansion of industrial production scale, the performance and reliability of double split rectifier transformer are higher requirement.

[0003] But the traditional double split rectifier transformer in the operation process, mainly relies on simple basic support structure to fix the equipment. These basic support structures usually adopt rigid connection mode, installs the transformer directly on the concrete foundation, is fastened through the connecting piece such as foundation bolt. Its technical principle is to utilize the stability of the foundation to bear the weight of the transformer, ensure that the transformer maintains a stationary state when operating normally. But this structure design has the deficiency when dealing with the vibration problem;

[0004] For example: the magnetostriction effect of the transformer inside the iron core, will cause periodic vibration; The current fluctuation generated when rectifier device works, also can cause electric power, and then cause the vibration of transformer, the existing rigid foundation support structure cannot effectively buffer and absorb these vibration energy. Under the long-term effect of vibration, the winding, iron core and other key components inside the transformer are prone to looseness, the winding looseness can change the insulation distance between windings, increase the risk of partial discharge, and even cause short circuit failure in severe cases, affect the normal operation of the transformer, and reduce its service life. UTILITY MODEL CONTENTS

[0005] The utility model discloses a double split rectifier transformer, which aims to solve the technical problem that the existing equipment's foundation support structure cannot effectively buffer and absorb the vibration generated by the equipment during operation, thereby causing the winding, iron core and other key components inside the transformer to looseness.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The utility model provides a double split rectifier transformer, including transformer body and cooling tower, the outer wall of transformer body is equidistant with heat dissipation plate, still include: the damping mechanism: the support seat of damping mechanism includes the outer wall of bottom of transformer body, the outer wall of both sides of support seat respectively installs two symmetrical distribution's first telescopic link, the outer wall of first telescopic link is equipped with third spring, one side of first telescopic link's outer wall is fixed with fixed seat, the inner wall of bottom of fixed seat is fixed with two connecting seat, the inner wall of connecting seat is connected with two limit block, the outer wall of top of limit block is connected with connecting rod, the outer wall of connecting rod is equipped with first spring, the both ends of connecting rod are connected with connecting rod respectively, one end of two connecting rod is connected with second telescopic link, the outer wall of second telescopic link is equipped with third spring, quick -detach mechanism: quick -detach mechanism is located in the inside of transformer body.

[0008] The support seat adopted in the scheme plays a role of bearing the weight of the transformer body, and enables the damping mechanism to be stably connected with the transformer body. When the transformer vibrates, the first telescopic link can perform telescopic movement along the axial direction.

Secondly, the second telescopic link installed on the bottom of the support seat performs telescopic movement like the first telescopic link when the transformer body vibrates. The outer wall of the second telescopic link is also equipped with the third spring, thereby buffering the transformer body again by using the third spring. In particular, when the second telescopic link performs telescopic movement, the force received by the second telescopic link is transmitted to the connecting rod, and at this time, the connecting rod moves together with the first spring equipped on the outer wall, thereby buffering the movement of the connecting rod by using the elasticity of the first spring, further consuming vibration energy and reducing the transmission speed of the vibration. At the same time, the bottom of the connecting rod is connected with the limit block on the outer wall, thereby enabling the connecting seat to guide the limit block to move in the limit slot formed in the inner wall of the connecting seat. At this time, the vibration intensity transmitted to the transformer body is greatly reduced through multiple buffering and energy absorption.

[0009] In a preferred scheme, the quick-detach mechanism includes second springs installed in the inside of the transformer body. One side of the outer wall of the two second springs is connected with the same filter plate. The other side of the outer wall of the second springs is connected with the clamping block.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0019] The utility model discloses a kind of double split rectifier transformers, mainly applied to the magnetic magnetostriction effect of its internal core when transformer works, periodic vibration can be caused;Current fluctuation produced when rectifying device works, also can cause electric power, and then cause the vibration of transformer, the scene that existing rigid foundation support structure cannot effectively buffer and absorb these vibration energy.

[0020] Referring to Figure 1 , Figure 2 and Figure 3 , a double split rectifier transformer, comprising a transformer body 1 and a cooling tower 2, the outer wall of transformer body 1 is equidistantly distributed with heat dissipation plates 3, further comprising: a shock absorbing mechanism: the shock absorbing mechanism comprises a support seat 15 installed on the bottom outer wall of the transformer body 1, two symmetrically distributed first extension rods 5 are installed on the outer walls on both sides of the support seat 15, a third spring 16 is sleeved on the outer wall of the first extension rod 5, a fixed seat 4 is fixed on one side of the outer wall of the first extension rod 5, two connecting seats 7 are fixed on the inner wall of the bottom of the fixed seat 4, two limiting blocks 12 are connected to the inner wall of the connecting seat 7, a connecting rod 10 is connected to the top outer wall of the limiting block 12, a first spring 11 is sleeved on the outer wall of the connecting rod 10, two connecting rods 9 are respectively connected to the two ends of the connecting rod 10, a second extension rod 6 is connected to one end of the two connecting rods 9, and a third spring 16 is sleeved on the outer wall of the second extension rod 6; quick release mechanism: the quick release mechanism is located in the interior of the transformer body 1.

[0021] In this design, the support base 15 serves to bear the weight of the transformer body 1 and simultaneously ensures a stable connection between the vibration damping mechanism and the transformer body 1. When the transformer vibrates, the first telescopic rod 5 can extend and retract axially. During the extension and retraction of the first telescopic rod 5, the third spring 16 is correspondingly compressed, thereby absorbing vibration energy through elastic deformation and providing initial vibration buffering. At this time, it is installed on the bottom inner wall of the fixed base 4 via two connecting seats 7. Secondly, the second telescopic rod 6 installed at the bottom of the support base 15, like the first telescopic rod 5, extends and retracts when the transformer body 1 vibrates. Simultaneously, its outer wall is also fitted with a third spring 16, thus utilizing... The third spring 16 acts as a buffer for the transformer body 1. Specifically, when the second telescopic rod 6 extends or retracts, the force it receives is transmitted to the connecting rod 10 through the connecting rod 9. At this time, the connecting rod 10 moves together with the first spring 11 sleeved on the outer wall. The elasticity of the first spring 11 itself acts as a buffer for the movement of the connecting rod 10, further consuming vibration energy and slowing down the transmission speed of vibration. At the same time, the bottom two sides of the connecting rod 10 are connected to the outer wall of the limiting block 12, so that the connecting seat 7 guides the limiting block 12 to move the connecting rod 10 in the limiting groove opened on its inner wall. At this time, through multiple buffering and energy absorption, the vibration intensity transmitted to the transformer body 1 is greatly reduced.

[0022] The second telescopic rod 6 is installed on the bottom inner wall of the fixed base 4, which provides an installation position for the components of the internal damping mechanism.

[0023] Specifically, the first spring 11 is connected to both ends of the connecting rod 10. When the transformer body 1 vibrates during operation, the vibration is transmitted to the connecting rod 10 through the connecting rod 9, which causes the first spring 11 to undergo elastic deformation and the connecting rod 10 to extend and retract. At this time, by extending the path and time of vibration transmission, the vibration energy is gradually consumed and weakened during the transmission process.

[0024] Specifically, both ends of the connecting rod 10 are telescopic structures, which guide the movement trajectory of the first spring 11.

[0025] Reference Figure 4 and Figure 5 In a preferred embodiment, the quick-release mechanism includes a second spring 13 installed inside the transformer body 1. The same filter plate 8 is connected to one outer wall of the two second springs 13, and a locking block 14 is connected to the other outer wall of the second springs 13.

[0026] By pulling the clamping block 14 towards the filter plate 8, the second spring 13 is compressed, and the clamping block 14 can be smoothly separated from the groove in the transformer body 1, so that the filter plate 8 can be quickly disassembled from the transformer body 1, greatly improving the convenience and efficiency of maintenance work.

[0027] The inner wall of the transformer body 1 is provided with a groove matched with the clamping block 14, and the clamping block 14 is pulled to separate from the groove in the transformer body 1, thereby achieving disassembly of the filter plate 8.

[0028] Referring to Figure 1 and Figure 2 In a preferred embodiment, the cooling towers 2 are symmetrically and equidistantly distributed on the top outer wall of the transformer body 1, and the outer wall of the cooling tower 2 is provided with multiple layers of heat dissipation pipes.

[0029] The cooling tower 2 is used for heat dissipation of the transformer body 1.

[0030] Working principle: when the transformer body 1 is vibrated due to internal electromagnetic force, mechanical operation and other reasons, the supporting seat 15 installed on the bottom outer wall of the transformer body 1 will first bear the vibration, and the third spring 16 sleeved on the outer wall will be compressed through the axial extension and contraction of the first extension rod 5, so that the third spring 16 is elastically deformed to absorb vibration energy, thereby achieving the effect of preliminary buffering vibration, at the same time, the second extension rod 6 installed at the bottom of the supporting seat 15 will also extend and contract when the transformer body 1 vibrates, at this time, the third spring 16 sleeved on the outer wall of the second extension rod 6 buffers the vibration again to further consume vibration energy, in the contraction process of the second extension rod 6, the force received by the second extension rod 6 will be transmitted to the connecting rod 10 through the connecting rod 9, with the movement of the connecting rod 10, so that the first spring 11 is elastically deformed, and the movement of the connecting rod 10 is buffered, thereby further slowing down the transmission speed of the vibration, at this time, the limiting block 12 connected to the outer wall of the bottom of the connecting rod 10 moves in the limiting groove in the inner wall of the connecting seat 7, the cooperation of the limiting block 12 and the limiting groove not only guides the movement track of the connecting rod 10, but also ensures the stability of the whole vibration buffering mechanism in the working process, through the multi-stage buffering and energy absorption mechanism, the vibration intensity of the transformer body 1 is greatly reduced, the key components such as the winding and the iron core in the transformer are protected, the problems such as loosening and damage of the components caused by vibration are prevented, and the service life of the transformer is prolonged, secondly, when the filter plate 8 needs to be replaced or cleaned, the operator pulls the clamping block 14 towards the filter plate 8, and the clamping block 14 is connected to one side of the second spring 13, so that the second spring 13 is compressed when the clamping block 14 is pulled, at this time, a groove matched with the clamping block 14 is formed in the inner wall of the transformer body 1, and the clamping block 14 can be smoothly separated from the groove when the second spring 13 is compressed, so that the filter plate 8 can be quickly disassembled from the transformer body 1, and the fast disassembly mechanism greatly improves the convenience and efficiency of maintenance work, reduces the equipment downtime caused by complicated maintenance work, and ensures the continuous and stable operation of the transformer.

[0031] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. The replacement can be a partial structure, device, method step replacement, or a complete technical solution. According to the technical scheme and the utility model concept of the present application, equivalent replacement or change should be covered within the protection scope of the present application.
