    摘要: A puffer type gas insulated circuit breaker has releasably engaging stationary and movable arc contacts contained in a vessel filled with an arc extinguishing gas. An operation rod serving as a supporting member of the movable arc contacts has openings and helps define a puffer chamber. In the breaker, gas is pressurized by an arc generated between said stationary arc contacts and said movable arc contacts in an initial breaking phase, this gas being taken into the puffer chamber. The holes are used as a heat exhaust passage.

    摘要: A circuit breaker actuator device of the type comprising an operating wheel (R) whose rotation drives the moving circuit-breaking members, said wheel being connected to a first spring (S'1) by a first chain (C1) passing over a first pulley (P1) and fixed to a first point (A1) close to the periphery of the wheel. The wheel is held fixed when the spring (S1) is under tension/compression by means of a retaining member (K1) which can be retracted to allow the wheel to rotate. The device further includes a second spring (S2) connected by a second chain (C2) passing over a second pulley (P2) and fixed to a second point (A2) on said wheel. The center of the wheel is situated, when both springs are under tension/compression, between the length of the first chain connecting the first point to the first pulley and the length of the second chain connecting the second point to the second pulley, with the second spring applying a force which is less than the force applied by the first spring.

    摘要: Circuit interrupting apparatus for interrupting large direct currents comprising a plurality of parallelly connected branch circuits each including a circuit breaker and a saturable reactor connected in series therewith, and a commutating circuit including a capacitor. When opening the circuit breakers the commutating circuit is connected across the branch circuits to pass commutating current in the direction opposite to the normal load current. When the current decreases below a predetermined value, the saturable reactors desaturate to efficiently interrupt the load current.

    摘要: In a gas insulated disconnecting switch, a movable contact assembly comprises a stationary cylinder, a coaxial cylindrical movable conductive contact, and a coaxial rod-shaped movable arc electrode. A compression chamber is formed between the stationary cylinder and the movable conductive contact. A damping chamber is formed between the movable conductive contact and the movable arc electrode. Because of controlled flow of gas into and out of these chambers, the speed at which the movable arc electrode is brought into contact with the stationary arc electrode is restricted and possibility of breakage of the arc electrodes is eliminated.
