Publication number: 20220319757Abstract: Provided in the present invention is a 220 KV transformer movable sleeve for easy maintenance which includes a sleeve assembly and a connecting component. The sleeve assembly includes a sleeve and an end cap, and the access port is provided on the sleeve, the access port is matched with the end cap, and the connecting component includes a rotating part, a moving part and a driving part. The access port is arranged on the sleeve assembly, and the inspection can only be carried out by opening the access port during inspection, without dismantling the entire movable sleeve, and greatly improving the work efficiency. The rubber strip is combined with the metal sleeve. The method reduces the influence of magnetic flux leakage on the metal movable sleeve and prevents it from generating eddy current heating. Through the driving part, the end cap can be automatically opened, saving time and effort.Type: ApplicationFiled: April 1, 2022Publication date: October 6, 2022Inventors: Liren ZHOU, Yuqing SANG, Yan SUN, Shuang HAO, Guoping TONG, Zhengrong LI, Jie LV
