Abstract: In allusion to the problems which caused by safe distance during the process of modifying and extension project in transformer substation, this paper analyzed the hoisting method of high voltage disconnector in common use. A set of simple hoisting device for high voltage disconnector was designed according to the practical situation in hoisting process. This paper expounded the design process of electrical and mechanical parts. The device could be used in the modification works of many high voltage disconnectors, such as GW7、CR、DR、S3CDT, with the advantages of powerful functions, small volume, easy assemble and reliable performance.
Key words: high voltage disconnector; hoisting device; safe distance; modification works
