High-voltage switch moves contact mechanism and uses high-voltage switch of this mechanism

The utility model relates to a high-Voltage electrical appliances field has especially involved a high-voltage switch moves contact mechanism and uses high-voltage switch of this mechanism. High-voltage switch moves contact mechanism including the moving contact that uses the front end for the end of pegging graft, the moving contact along the assembly of axial direction on guide rail parts, in addition, be equipped with axial through's through-hole in the moving contact, in the through-hole perhaps the one end department fixation of through-hole has the nut, is equipped with the lead screw in the nut, and the front end of lead screw extends to in the through-hole of moving contact. In fact nut and lead screw have formed screw nut mechanism, and the moving contact is together fixed with the nut, consequently, are ordering about the in-process of moving contact along axial reciprocating motion through the lead screw, and lead screw itself does not have axial motion to the required space in lead screw rear portion can be reduced, and then the present bulky problem of high-voltage switch can be solved.
