VACUUM HIGH-VOLTAGE SWITCH

摘要

A vacuum high-voltage switch, comprising a frame, poles with vacuum arc-suppressing chambers, insulating rods with compression springs, a switch shaft, an electromagnetic drive, block-contacts of the switch position, manual off-mechanism, boards of protection and control circuits, characterized in that said poles with vacuum arc-suppressing chambers are arranged vertically in series on the frame and kinematically connected via the isolating rods comprising compression springs, the switch shaft mounted horizontally beneath the poles, said shaft is connected via the regulating rod with one electromagnetic drive, in which a laminated core, in and off coils, an armature and constant magnets form two magnetic circuits , capable to retain the armature in its both extreme positions, wherein the electromagnetic drive comprises a mechanism of switching-in blocking, and the switch shaft is connected kinematically to the block-contacts of the switch position.
