    摘要: According to the present invention there are provided a highly reliable electrode of high strength which undergoes little change even with the lapse of time, and a method for making the same, as well as a vacuum valve using such electrode and a vacuum circuit breaker using such vacuum valve. The vacuum circuit breaker has a fixed electrode and a movable electrode, each comprising an arc electrode, an arc electrode support member for supporting the arc electrode, and a coil electrode contiguous to the arc electrode support member, the arc electrode, the arc electrode support member and the coil electrode being formed as an integral structure by melting, not by bonding, particularly the arc electrode support member and the coil electrode being constituted by a Cu alloy containing 0.05-2.5% by weight of at least one of Cr, Ag, W, V and Zr.

    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.
