摘要： A breaker comprises a stator (3) having a fixed contact (2), a mover (5) having a movable contact (4) that is swingably supported by a shaft (7) and can be separated from the fixed contact (2) and brought into contact with it, and a shunt conductor (10) having one end fixed to the rear end of the mover (5) opposite to the movable contact (4) with respect to the shaft (7) and the other end connected to a terminal (9). The breaker is so structured that the magnetic flux produced by a current flowing through the shunt conductor (10) and the electromagnetic force due to the current act on the mover (5) to move the movable contact (4) toward the fixed contact (2). The length from the shaft (7) of the mover (5) to the rear end is two or more times the distance from the shaft (7) to the movable contact (4) in the horizontal direction. One end of the shunt conductor (10) is secured directly to the rear end of the mover (5).

摘要： In an operation circuit of an electromagnetic switching device, when electric energy is discharged by discharge switches connected in series, respectively, to opening coils and closing coils, an induction current flowing in a direction opposite to a current of the coil of the excitation side is generated. The current flows through the coil on the non-excitation side due to magnetic coupling, and a magnetic flux necessary for driving is cancelled, thereby inhibiting generation of a driving force. The operation circuit includes first and second opening and closing coils, so that a moving element may be driven between those coils. This circuit includes a circuit for suppressing an over-voltage at the moment of interrupting an excitation current of a first coil and for interrupting an induction current generated through the first coil at the time of exciting the second coil.

摘要： The device includes a container (2) filled with an insulating gas and receiving the insulating tubes (8) and having vacuum-case valve circuit-breakers (7) for individual phases. An end of each insulating tube is fixed to the interior of the container. Each valve circuit breaker is installed on a common longitudinal axis with the corresponding insulating tube, of the type that the movable electrode rod (7b) is directed towards the fixed end of the insulating tube. The insulating tube includes, in so far as its formed part from a first holder, a fixation part from a busbar line (8b) projecting itself in the direction which cuts the longitudinal axis from one side near its opposed ends w.r.t the fixed extremity, in the abutment of the supporter, a conductor on one bus side (14) in an insulated manner.

摘要： In a vacuum interrupter comprising a disc-shaped stationary electrode and a disc-shaped movable electrode arranged in an evacuated envelope in opposed relationship, a slot or a salient part is formed on the surface of both the electrodes and thereby a path of an arc current in disconnection operation of both the electrodes is formed along the circumference of the disc-shaped electrode. The shape and position of the slot is selected so that the arc current flows uniformly along the entire circumference of both the electrodes.
