    摘要: An interrupter including a gas pressurizer for pressurizing a gas to flow toward a forward end of at least one contact of the interrupter, and a first orifice forming a first space with the forward end of the at least one contact for passing the gas pressurized by the gas pressurizer when a flow of electric current is interrupted. A second orifice forms a second space with the at least one contact for passing the gas which passed through the first orifice, with a chamber being formed between the first and second orifices. The chamber has an inner diameter greater than an inner diameter of the first and second orifices. At least one pressurized gas passage is provided through which a portion of the pressurized gas is supplied to the chamber without passing the first orifice so that the pressurized gas supplied to the chamber through the pressurized gas passage flows to the first space formed by the forward end of the at least one contact and the first orifice.

    摘要: A puffer type gas-blast circuit breaker includes a guide section arranged at a coupler section between a shaft section of a puffer cylinder and a dielectric operating rod, for guiding both in the axis direction of a current interruption section and in the radial direction thereof, thereby to suppress or eliminate the occurrence of misalignment of center axis between movable components and fixed ones thus causing a gap to remain constant between a dielectric nozzle and a fixed arc contact. With such an arrangement, the gap between the nozzle and the contact can be kept uniform even when the pole-to-pole distance is increased with an increase in the high withstanding voltage of the breaker. This ensures that the surface-creeping electric field on the inner surface of the dielectric nozzle can be at a desired design value, thus enabling to provide a stable pole-to-pole insulation characteristic during current interruption operations.
