摘要： A puffer-type gas blast circuit breaker is capable of restraining reduction in creepage insulation resistance of an insulating support and an insulating rod due to insulating gas of high temperature. An electrode section is mounted on a stationary member supported on an insulating support, and a stationary side arc contact and moving side arc contact are disposed facing each other to contact and separate; a hollow piston rod and an insulating rod are connected to the moving side arc contact, and inserted in a stationary member body portion; and a gas flow blocking member is mounted on an end of the piston rod to prevent an insulating gas heated and coming to the stationary side from getting into the insulating rod side. The stationary member body portion is formed cylindrical so that a gap between the body portion of the stationary member and the gas flow blocking member is minimized.

摘要： A gas-circuit breaker includes a cylinder, a stationary piston, and a moving piston. The cylinder has a moving contact that is fixed on one end of a rod and has a gas exhaust that faces a stationary contact. The rod is inserted into the cylinder. The stationary piston is fixed to the container, and is fitted in an opening of the cylinder to create a puffer chamber. Due to movement of the rod, the stationary piston compresses arc-extinguishing gas, and the gas blows onto the arc through gas exhaust. The moving piston partitions the puffer chamber into a first puffer chamber and a second puffer chamber. Sliding of the moving piston changes the capacity of the first puffer chamber and the second puffer chamber according to the difference in pressure in the first puffer chamber and the second puffer chamber.

摘要： A target-closing phase-map generating section generates in advance a target closing phase map in consideration of a pre-arc characteristic and variations of a mechanical action of a breaker, and amplitude fluctuations of the load voltage. A target-closing time calculating section calculates a target closing time string from frequencies and phases of the power source voltage and the load voltage, respectively, of the breaker referring to the target closing phase map. A closing control section, when a close command 11 is inputted, controls the timing of outputting a closing control signal based on a predicted closing time and the target closing time string.
