Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of transformers, and particularly relates to a shock insulation device structure. BACKGROUND

[0002] A transformer is a device for changing AC voltage by using the principle of electromagnetic induction. Transformer loss accounts for about 40% of power transmission and distribution power loss, and has great energy-saving potential. Therefore, as a basic equipment for power transmission and distribution, the transformer is widely used in industrial, agricultural, transportation and urban community fields.

[0003] When the transformer is working normally, it will usually generate vibration, and the reasons for generating vibration are as follows:

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

[0005] 2) The electromagnetic force in the transformer is unbalanced due to the difference between the magnetic field in the transformer and the magnetic permeability of the core, which is also an important reason for vibration;

[0006] 3) During the operation of the transformer, the transformer itself has a large volume, so it will generate a certain vibration to the support and foundation structure;

[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
