A high-voltage triplepole vacuum switch comprises three vacuum arc extinguishing chambers with stationary and movable contacts located therein, a support insulations, a mechanism for movable contacts control, the mechanism for movable contact control comprises series and functionally related a regulating member capable of rotation and connection of a power element, a disc made at least with one recess, two spiral springs, each of which is pressed to the disc; an insulator rigidly connected to the disc, having three similar pushers, each of which has a groove with a bearing installed therein and set on an axle, a bearing valve having two fixing bearings. The regulating element is made as an axle-regulator, both springs are made rotatable. In addition, the second disc is incorporated, which is made with a recesses and a supporting flange, a body made from two connected plates parallelly installed on supporting plate at a distance one from another; both discs rigidly installed on the axle-regulator and the bearing valve are located in the body. |
