Abstract

The invention relates to a three-pole high-voltage circuit breaker with a device for synchronous closing or opening in relation to the phase position of voltage or current in the respective poles. The breaker has an operating mechanism with a rotary shaft (5) which is common to all the poles. The necessary time-lag between the instants of closing or opening in the different phases is brought about by mechanical means by connecting the movable contact (2) in each pole to the common rotary shaft (5) via an operating rod (3) and a crank lever (4) fixed to the shaft, the angle (aR, aS aT) between the crank lever and the direction of movement of the movable contact in one of the breaker poles differing in magnitude from the corresponding angle (aR, aS aT) in at least one of the other poles. By mutual adaptation of the lengths of the three crank levers (4), the same length of contact travel (s<5>) in the different breaker poles can be obtained.
