Document Type and Number:
WIPO Patent Application WO/2018/090549
Kind Code:
A1
Abstract:
An ultra-high-voltage power line disconnector, comprising a housing, double-break switch units, and drive mechanisms. N sealed chambers communicated in sequence are provided in the housing; a set of double-break switch units and a set of drive mechanisms are provided in each chamber; the double-break switch unit comprises contact bases, a pair of movable contacts, and a pair of fixed contacts; the movable contact base is provided in the middle of the chamber; the pair of fixed contacts are respectively disposed at opposite sides of the movable contact base; the pair of movable contacts are disposed inside the movable contact base and can extend out of the movable contact base from opposite directions to contact and work in concert with the corresponding fixed contacts; the pair of movable contacts are driven, by means of the drive mechanisms, to reciprocate synchronously, and simultaneously contact the fixed contacts or are simultaneously separated from the fixed contacts; the pair of movable contacts are conductively connected to each other; the double-break switch units in each chamber can be separated or connected synchronously by means of the drive mechanisms. The advantage is that the ultra-high-voltage power line disconnector uses a three-phase linkage mechanical transmission structure so that the transmission is stable and reliable.
