The center of column sleeve pipe, insulated pull rod and driving mechanism is on same straight line；
The quiet main contact is to the center convex of quiet main touching cylinder, and the surrounded diameter of a circle of quiet main contact is less than dynamic main contac outer wall institute
Surround diameter of a circle；
It further include the composite insulating arc blowout chamber casing being wrapped in outside on off mechanism, the first end of composite insulating arc blowout chamber casing is set
There is the outlet connecting plate with composite insulating arc blowout chamber casing connection；The outlet connecting plate is connected with quiet main touching cylinder；
The second end of composite insulating arc blowout chamber casing is connected with compound inslation pillar sleeve, and compound inslation pillar sleeve is set in absolutely
Outside edge pull rod；
Interconnecting piece between composite insulating arc blowout chamber casing and compound inslation pillar sleeve is equipped with inlet wire connecting plate；In the middle part of inlet wire connecting plate
There is through-hole, through-hole passes through insulated pull rod；Inlet wire connecting plate is connected with main touching cylinder is moved；

Connecting terminal；Inlet wire connecting plate is connected with inlet wire connecting terminal；
It is equipped with mechanism case outside driving mechanism, the end of compound inslation pillar sleeve is connect with mechanism cabinet；
Insulated pull rod includes the drive connection section connecting with driving mechanism, the moving contact that is connect with moving contact component pull section and
Make to be drivingly connected the connector that section pulls section to connect with moving contact；
Connector is equipped with sequentially connected first linkage section, intermediate connecting section and the second linkage section；
First linkage section protrudes into moving contact and pulls in section, pulls section interference fit with moving contact, and moving contact is made to pull section
End is held on intermediate connecting section；
Be drivingly connected section to protrude into the second linkage section, be drivingly connected section and the second linkage section and be interference fitted, and be drivingly connected section with
Second linkage section is equipped with compatible pin hole, is drivingly connected section and is connect with the second linkage section by pin shaft.
