Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to a seismic isolation device structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Transformer losses account for about 40% of power transmission and distribution losses and have great energy-saving potential. Therefore, as the basic equipment for power transmission and distribution, it is widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] When the transformer is working normally, it usually generates vibration. The reasons for the vibration are as follows:

[0004] 1) When the transformer is running, due to the electromagnetic induction effect, some electromagnetic forces will be generated, which act on the transformer and cause the transformer to vibrate;

[0005] 2) Due to the difference in magnetic field inside the transformer and the magnetic permeability of the iron core, the electromagnetic force inside the transformer will be unbalanced, which is also an important reason for vibration;

[0006] 3) During the operation of the transformer, due to the large size of the transformer itself, it will cause certain vibrations to the support, foundation and other structures;

[0007] The vibration generated by the transformer during operation can easily reduce the supporting effect of the transformer base (i.e. the supporting part) on the entire transformer after long-term use, so a device is designed to solve this problem. Summary of the invention

[0041] It should be noted that the invention does not limit the number of dampers 4 provided on each group of sides, but the dampers 4 provided on each group of sides of the bottom plate 204 should correspond one-to-one with the dampers 4 provided on the other group of sides corresponding to the dampers 4.

[0042] refer to Figure 1 and Figure 3 Partial structure, the connecting component 5 includes a slider 51, a side connecting plate 52 and a connecting column 53.

The upper surface of the slider 51 is fixedly connected to a first ear plate 54, and the lower surface of the side connecting plate 52 is fixedly connected to a second ear plate 55. The two ends of the connecting column 53 are rotatably connected to the first ear plate 54 and the second ear plate 55 respectively.

[0043] It should be noted that both the upper connecting plate 202 and the side connecting plate 52 can be connected to the lower surface (ie, the bottom of the box) of the transformer body 3 by bolts.

[0045] In actual use, when the transformer vibrates during use and tilts toward the side close to the transmission block 67, the connecting component 5 close to the side of the transmission block 67 will drive the slider 51 connected to it to slide, and the slider 51 will drive the transmission belt 62 to rotate. The transmission belt 62 cooperates with two sets of pulleys 61, the driving gear 63, the transmission gear 64, the driven gear 65 and the rack 66 to drive the slider 51 away from the side of the transmission block 67 to slide, and vice versa. Through this arrangement, the transformer body 3 will not tilt to one side due to vibration, and by connecting the slider 51 to the damper 4, the vibration can be further reduced.
