摘要： A vacuum circuit breaker comprising an external coil which is arranged outside a vacuum interrupter, and a power supply circuit which causes current to flow through the external coil. An overcurrent flowing through the main circuit of the circuit breaker, which leads to a load, is detected by an overcurrent tripping device so as to separate the movable electrode of the vacuum interrupter from the fixed electrode thereof and to subject a striking electric arc to a magnetic flux generated axially of the vacuum interrupter by the electrodes themselves. Thereafter, a trigger gap is ignited by a signal delivered from the overcurrent tripping device, so as to introduce a reverse current into the vacuum interrupter. Herein, the trigger gap is ignited by a signal delivered from the overcurrent tripping device, in order that the zero point of currents may be formed at the point of time at which the axial magnetic flux has been canceled by the resulting current of the external coil. Since the axial magnetic flux remaining at the zero point of the currents is nullified, charged particles are not hindered from diffusing radially of the vacuum interrupter, and hence, an enhanced breaking performance is attained.

摘要： A cylindrical coil electrode incorporated in a vacuum interrupter comprises a cylindrical body having an opening at one end thereof, two electrical connections provided between the edge surface of the opening of the cylindrical body and a main electrode, two arcuate slits formed on the cylindrical body between the two electrical connections, two arcuate current paths formed in the cylindrical body by the arcuate slits beginning as a respective electrical connection and ending at a rod, and two current blocking slits formed on the cylindrical body at positions where one end of each of the current paths laps the other end of the other current paths. Because of the above structure, one-turn current flows throughout the current paths so that a uniform axial magnetic field can be applied to the main electrode, and an arc current can be uniformly distributed over the entire surface of the main electrode, thereby improving the current interruption performance of the vacuum interrupter.

摘要： A vacuum interrupter comprises a pair of electrodes separably arranged within a vacuum vessel and mounted on conductor rods respectively. Each of the electrodes includes a coil electrode and a main electrode. The coil electrode is adapted to branch the current in the conductor rod in different radial directions with respect to the conductor rod for generating magnetic fields in axial direction of said conductor rod in such a manner as to offset each other at points near to the conductor rod. The main electrode is electrically connected with the coil electrode for carrying an arc. The main electrode includes a plurality of first current paths for passing the current in different radial directions, a plurality of second current paths for passing the current from the coil electrode to the first current paths, and a plurality of third current paths for passing the current therein in opposite directions to the current in the second current paths. Magnetic fields are generated in the main electrode in the same axial direction as those generated in the coil electrode, with the result that the arc is extinguished quicker when compared with the case where only one of the main and coil electrodes generates the axial magnetic field, thus improving the current-interrupting performance.

摘要： A vacuum interrupter comprises a pair of opposed conductor rods extending exteriorlly of a vacuum vessel, a pair of main electrodes mounted to ends of the paired conductor rods and separable from each other, and coil electrodes which induce axial magnetic flux acting on arc produced when one main electrode separates from the other main electrode. The coil electrode includes a first arm section connected to the conductor rod and passing the current coming from one portion of the conductor rod radially thereof, a branching section for branching the current from the first arm section in reverse directions, and a second arm section for passing the branched currents until they are totalized again at the other portion of the conductor rod separated from the one portion by a spacer interposed between the first and second arm sections, whereby magnetic flux induced by the branched currents is cancelled out at the conductor rod, preventing the generation of eddy current in the conductor rod.

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.
