FIELD: vacuum devices.
SUBSTANCE: invention relates to a vacuum switch assembly with medium voltage interrupter including cabinet (20), which has supports (11) for each output, casing consisting of two halves (14, 15) made of insulation material, each of which contains pairs of opposite fixed contacts (16, 17), which can be separately connected to pairs of blade contacts (18). Blade contacts (18) rotate alternately and selectively until they touch one or another of two fixed contacts (16, 17) connected to at least one user or to a ground connection in closed and open positions. Blade contacts (18) are located on plate (21), which rotates by means of a control shaft and has a cam drive, which, on the one hand, provides for close and open position of fixed contacts (16, 17) and blade contacts (18) and, on the other hand, provides for connection or disconnection of movable and fixed contacts of vacuum switch (30).
EFFECT: technical result is an increase in accuracy of assembly and simplification of assembly and operation.
