摘要

The invention relates to electric power and can be used in high-voltage vacuum circuit breakers. Technical result of utility model - a decrease in vertical dimensions and increase ease of use. Based on the carcass (1) are arranged three phase poles (2), each of which contains enclosed in insulators (3), two extinguishing chambers (4). Each chamber (4) has a fixed contact (5) for connecting an external busbar, and a movable contact (6) which is electrically connected to the movable contact (6) of the other arc extinguishing chamber (4) and kinematically - through a distribution mechanism (7) placed in a housing (8) and an insulating rod (9) with a common spring drive (10) switch, placed under the base (1). The distribution mechanism (7), the poles (2) mounted on a support insulator (11) inside which an insulating rod (9) is arranged, and the insulators (3) from the arcing chambers (4) are fixed on the housing (8) of the distribution mechanism (7) in cantilever fashion to a support insulator (11). The kinematic connection of the movable contact (6) of the extinguishing chamber (4) to the distribution mechanism (7) is formed as a rod (12) fixed to move axially with the moving contact (6). The electrical connection between the movable contacts (6) chambers (4) is formed by fixed on the movable contact 6, the spring-loaded current collector (13) sliding in the sleeve (14) mounted in an end face of the insulator (3) for the distribution mechanism (7) and a current lead (15 ) connecting said sleeve (14) two chambers (4) arranged in the housing (8) of the distribution mechanism (7). The rod (12) is further secured in the bearing supports (16) movably. 3 z.p.f. 3 yl.
