AI Technical Summary
The dry transformers on the market have simple structure, poor protection performance, and lack of shock absorption devices, resulting in serious noise propagation and poor sound absorption and noise reduction effect.
The lower iron yoke is installed on both sides of the bottom of the dry transformer and is fixed by a stretching rib. The bottom foot and the lower iron yoke are connected by shock-absorbing components, including a buffer connection and a fixing piece. The rubber buffer pad is elastically connected to absorb energy, shock-absorbing and noise-absorbing.

[0021] Working principle: When the transformer body 1 is working, the four connections between the lower iron yoke 2 and the base 4 at the bottom are elastically connected through the first buffer connector 31, the second buffer connector 32, the third buffer connector 33 and the fourth buffer connector 34. The buffer pad 311 in the buffer connector can absorb energy, reduce vibration and reduce noise for the transformer body 1 when it is working.
[0022] As a preferred embodiment, the lower iron yoke 2 and the base foot 4 are evenly connected through the first buffer connector 31, the second buffer connector 32, the third buffer connector 33 and the fourth buffer connector 34, and the composition structure of the first buffer connector 31, the second buffer connector 32, the third buffer connector 33 and the fourth buffer connector 34 are consistent.

[0025] The upper and lower sides of the buffer pad 311 are clamped and fixed by the lower fixing plate 312 and the upper fixing plate 316; the lower fixing plate 312 and the upper fixing plate 316 have high strength and rigidity, which can significantly improve the overall load-bearing capacity and pressure resistance of the buffer pad 311; making it less likely to deform or be damaged when subjected to greater pressure or load.

Moreover, the silicon steel sheets are stacked using the seven-step method, which reduces the iron core joints and greatly reduces the reactive power consumed by the excitation at the iron core joints. Ultimately, the overall performance of the product achieves the effects of low loss and low noise.
