Abstract
Operating shaftallows disconnecting switch-side and earthing switch-side moving contactsandto linearly reciprocate with the rotation of operating shaft. Operating shafthas two-hole leverallow an arc motion. Each one end of two curved linksa andb is connected to two-hole leverand the other end of two curved linksandis respectively connected to the disconnecting switch-side moving contact or the earthing switch-side moving contact. When the two connecting points are axisymmetric with respect to the bisector, both the disconnecting switch and the earthing switch are in an open state; when two-hole levermoves at a predetermined angle to the disconnecting switch-side, the disconnecting switch is in a closed state; and when two-hole levermoves at a predetermined angle to the earthing switch-side, the earthing switch is in a closed state.
