Further, the static contact seat includes static contact and supporting insulator, and static contact is fixedly installed in supporting insulator On.

Further, the movable contact spring component includes two panels moving knife, intermediate pivot pin, upper tension spring and tension spring, upper tension spring position It is located at the lower part of moving knife in the top of moving knife, tension spring, the two ends of upper tension spring and tension spring are installed on moving knife by straight pin On.

Further, the intermediate pivot pin is ladder pivot pin, and mid diameter is greater than both ends diameter, and middle part is located at two panels moving knife Between.

Compared with prior art, the utility model advantage is:

(1) change conventional isolation switches integrated design, the static contact seat and disconnecting switch ontology of the utility model are fission Formula design, assembly flexibly, are not used equipment limit, can be by changing phase spacing and corresponding size, suitable for different occasions； It is applicable to single-phase to three-phase system.

(2) by merogenesis axis connection between disconnecting switch ontology, merogenesis axis can drive movable plate to rotate, and realize and close a floodgate and divide Lock；

(3) the movable contact spring component of the utility model simplifies structure, removes traditional to wearing bolt fastener, setting up and down two Group tension spring, reduces electrical body range, shortens insulation distance；Point discharge is reduced, safety and reliability are improved；Simplification was assembled Journey, contact pressure can be directly realized by by upper and lower two groups of tension springs, simplify debugging process.
