Description

Technical Field

[0001] The utility model relates to the field of power transformers, in particular to an anti-seismic protection type power transformer. Background Art

[0002] A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency. Since power transformers are necessary equipment for power transmission and distribution and power distribution to power users, power transformers play an important role in our production and life.

[0003] The Chinese utility model with patent application number CN202320286064.7 provides a seismic protection type power transformer. The shock absorbing device can not only enable the power transformer to be quickly installed or the mounting frame to be removed, but also the damping shock absorber can quickly reduce the vibration frequency of the power transformer, thereby reducing the shock of the power transformer. The protective device can protect the power transformer, reduce external scratches and impacts on the power transformer, thereby increasing the service life of the power transformer, and improve the heat dissipation performance of the power transformer through the heat dissipation device.

[0004] However, it was found during the use of the above-mentioned device that when installing the power transformer, the slot on the power transformer was aligned with the block on the shock-absorbing device to quickly insert it into the mounting frame. However, the block did not further fix the power transformer. When vibration occurred, the power transformer would swing left and right along the block, making it easy for the power transformer to hit the inner wall of the protective device, causing wear and damage, which would affect the service life of the power transformer. Utility Model Content

[0005] In view of the above problems, the utility model provides a seismic protection type power transformer. To achieve the above purpose, the utility model adopts the following technical solutions.

[0011] Preferably, a slide groove is provided inside the mounting seat, the slide rod is arranged in the slide groove, and one side of the slide block is connected to the inner wall of the slide groove through a spring.

[0012] According to the above scheme,

[0013] Compared with the prior art, the beneficial effects are as follows:

[0014] This solution can effectively limit the transformer body by setting a limit plate to match the groove at the bottom of the transformer body.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0022] Embodiment 1: As shown in the attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown, an earthquake-resistant power transformer comprises an outer shell 1 and a transformer body 5, wherein the transformer body 5 is installed inside the outer shell 1, a limit plate 13 is fixedly arranged at the inner bottom of the outer shell 1, a slideway 14 is provided inside the outer shell 1, a fixing assembly 4 is installed in the slideway 14, and the fixing assembly 4 comprises a bidirectional threaded rod 43, the bidirectional threaded rod 43 is arranged in the slideway 14, the bidirectional threaded rod 43 transversely passes through the bottom of a fixing plate 41, and an anti-slip plate 42 is fixedly connected to one side of the fixing plate 41;

[0023] A plurality of heat dissipation holes 11 are provided on the front and rear sides of the outer shell 1 , and circular heat dissipation holes 2 12 are provided on the left and right sides of the outer shell 1 . A shock absorbing assembly 3 is connected to the bottom of the outer shell 1 .

[0024] As can be seen from the above, the fixing plate 41 is used to clamp and fix the transformer body 5. When the transformer body 5 is installed inside the outer shell 1, the notch at the bottom of the transformer body 5 is aligned with the limit plate 13 at the bottom of the outer shell 1. The function of the limit plate 13 is to initially limit the transformer body 5, which can effectively prevent the transformer body 5 from moving forward and backward when encountering vibration.

[0025] A driving device is provided inside the outer shell 1, and the driving device controls the bidirectional threaded rod 43 to rotate. During the rotation of the bidirectional threaded rod 43, the fixing plate 41 through which the bidirectional threaded rod 43 passes moves, and the bottom of the fixing plate 41 fits with the inner wall of the slideway 14, so that the fixing plate 41 moves toward the transformer body 5 and clamps the transformer body 5 through the rotation of the bidirectional threaded rod 43. The anti-slip plate 42 connected to one side of the fixing plate 41 fits with the transformer body 5, and the transformer body 5 is clamped by the fixing plates 41 on both sides of the transformer body 5, so that the transformer body 5 can be further fixed, and the transformer body 5 can be prevented from moving left and right and shaking during vibration. At the same time, the friction between the anti-slip plate 42 and the transformer body 5 can effectively prevent the transformer body 5 from moving, which helps to further fix the transformer body 5.

[0026] The heat dissipation hole 11 and the heat dissipation hole 2 12 are used to improve the heat dissipation performance of the transformer body 5 . Meanwhile, a heat dissipation component can be added to the heat dissipation hole 2 12 to further dissipate the heat of the transformer body 5 .

[0027] Embodiment 2: As shown in the attached Figure 1 To Attachment Figure 3 As shown, on the basis of the first embodiment, a damping rod 21 is fixedly connected to the bottom of the outer shell 1, and the outer shell 1 is connected to the mounting seat 2 through the damping rod 21;

[0028] The damping rod 21 is installed at the bottom of the mounting seat 2, and the outer shell 1 is installed in the groove opened in the mounting seat 2. The size of the outer shell 1 is adapted to the inner groove of the mounting seat 2;

[0029] The shock absorbing assembly 3 includes a connecting arm 31, which is fixed to the bottom of the outer shell 1. The connecting arm 31 is rotatably connected to a connecting rod 32, one end of the connecting rod 32 is rotatably connected to a slider 33, a damping pad 331 is arranged in the middle of the slider 33, and the middle of the damping pad 331 passes through the slider 35 transversely;

[0030] A slide groove 22 is provided inside the mounting seat 2 , a slide rod 35 is arranged in the slide groove 22 , and one side of the slide block 33 is connected to the inner wall of the slide groove 22 via a spring 34 .

[0031] As can be seen from the above, the size of the outer shell 1 is adapted to the inner groove of the mounting seat 2, which helps to prevent the outer shell 1 from lateral movement when vibration occurs. The damping rod 21 and the shock absorbing assembly 3 at the bottom of the outer shell 1 can effectively reduce the vibration amplitude of the outer shell 1, protect the outer shell 1 and the transformer body 5 inside it, and reduce the impact of vibration on them;

[0032] When vibration occurs, the outer shell 1 moves downward together with the connecting arm 31, causing the connecting rod 32 to rotate, thereby changing the angle between the connecting rod 32 and the slider 33, thereby controlling the slider 33 to move to both sides on the slide bar 35. At the same time, the slider 33 squeezes the spring 34. The spring 34 and the damping pad 331 can effectively reduce the vibration of the transformer body 5, reduce the vibration amplitude and frequency, and thus achieve shock absorption protection for the equipment.

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
