摘要： A transformer station includes a plurality of power transmission lines receiving electric power, a bus bar connected to the power transmission lines, a transformer connected to the bus bar to transform voltage of the electric power supplied from the bus bar, and breakers between one of the power transmission lines and the bus bar and between the transformer and the bus bar. The breakers are aligned along an imaginary line extending substantially parallel to the bus bar.

摘要： Disclosed is a gas circuit breaker of resistance breaking type, which comprises a main breaking unit and a resistance contact mechanism electrically connected in parallel with the main breaking unit for resistively cutting off current. With the opening action of the main breaking unit, a spring used for opening the resistance contact mechanism is energized and the energized force of the spring is released by a releasing mechanism after the current in the main breaking unit is cut off, thereby to act as a drive force to open the resistance contact means.

摘要： A dielectric gas produced at the time of current interruption is exhausted into an exhaust structure 1 through an opening 8 formed on a fixed-side support member 6 combined with a fixed arcing contact 4. The exhaust structure 1 has an enlarged portion with a gas flow cross section formed at least before a position at 1/2 of the overall length of the exhaust structure 1 that is uniformly enlarged toward the rear of the exhaust structure 1 with respect to the joint between the exhaust tube 1 and the fixed-side support member 6. As a result, the gas is immediately exhausted into the exhaust structure 1 and the interelectrode insulation recovery performance is ensured.

摘要： A first puffer chamber is formed by a puffer cylinder having a substantially cylindrical flange portion and a shaft portion, and a fixedly disposed piston. The piston is formed in a cylindrical shape sealed with respect to an external space, and is constituted to be accommodated in the flange portion of the puffer cylinder at the circuit breaking position of the circuit breaking unit. The internal space of the piston is constituted as a second puffer chamber which is designed to communicate with the first puffer chamber. The gas accumulated in the second puffer chamber is continuously blown out toward between the electrodes, thereby prolonging an effective interruptable arc time span without increasing the size of the circuit interrupting unit and operating unit.

摘要： A grounded support tank type gas circuit breaker comprising a cylindrical tank maintained at ground potential and filled with an arc-extinguishing gas, and a breaking unit disposed within the tank with its central axis extending along the axis of the tank. In the circuit breaker, a capacitor unit is disposed within the tank in axially aligned relation with the breaking unit with its axis extending along an extension of the central axis of the breaking unit, so that the capacitor unit can be easily incorporated in the circuit breaker by merely increasing the axial length of the tank.

摘要： In a magnetic puffer type gas circuit breaker including an electromagnetic coil through which a current to be interrupted flows during the breaking operation, and an electromagnetic repulsive member which produces an electromagnetic repulsive force in cooperation with the electromagnetic coil and drives movable parts of a breaking portion of the apparatus, the electromagnetic repulsive member is so arranged that the electromagnetic neutral position of the electromagnetic repulsive member within the electromagnetic coil at the time when the breaking portion has been closed deviates on the closing side with respect to the electromagnetic center of the electromagnetic coil. Further, the characteristics of the electromagnetic repulsive forces between the electromagnetic coil and the electromagnetic repulsive member are so set that their absolute values become smaller on the closing side than on the breaking side with respect to the point at which the electromagnetic center of the electromagnetic coil and the electromagnetic neutral position of the electromagnetic repulsive member are coincident.
