AI Technical Summary

Technical Problem

When transporting ultra-high voltage transformers with large capacity, it is necessary to ensure the safety and reliability of the unit body and fuel tank housing in harsh environments, especially to offset the impacts that may occur during transportation.

Method used

A device for the overall limit of the road transport body of a million-unit transformer is designed, including the body and the limiting device. The body is composed of the transformer oil tank cover, side wall, box bottom, and iron core web upper and lower clamps. The limiting device includes a damping limiting device, an upper and lower limit guide column and a rotating eccentric limiting ring assembly. Through these devices, the overall limiting and impact absorption of the body is achieved.

Benefits of technology

It effectively meets the transportation needs of transformers above 500t level, ensures the support strength of the unit body, and offsets the possible impact in transportation through limiting devices, reduces the risk of impact damage to the transformer during transportation, and ensures the safe transportation of the unit body and fuel tank.
