Title:
DOUBLE-BREAK ISOLATED SWITCH MODULE
Document Type and Number:
WIPO Patent Application WO/2018/090548
Kind Code:
A1
Abstract:
Disclosed is a double-break isolated switch module, comprising a housing, double-break switch devices and driving mechanisms, wherein the housing is internally provided with n sequentially connected sealed cavities, each having a group of double-break switch devices and a group of driving mechanisms; the double-break switch device comprises a movable contact holder, a pair of movable contacts and a pair of stationary contacts; the movable contact holder is arranged in the middle of the cavity; the pair of stationary contacts are respectively arranged on two opposite sides of the movable contact holder; the pair of movable contacts are arranged inside the movable contact holder and can extend out of the movable contact holder in opposite directions to cooperate with the corresponding stationary contacts; the pair of movable contacts are driven by the driving mechanism to carry out synchronous reciprocating linear motion, and simultaneously touch the stationary contacts or are simultaneously separated from same; the pair of movable contacts are mutually conductive; and the double-break switch device in each cavity realizes synchronous switching on or off by means of the driving mechanism. The advantage is that the double-break isolated switch module uses a three-phase linkage mechanical transmission structure, and the transmission is stable and reliable.
