摘要： A current interruption apparatus comprises a series-connected combination of at least one vacuum interrupter and at least one gas-blast interrupter. Each vacuum interrupter is coupled in parallel with a non-linear resistor, while each gas-blast interrupter is coupled in parallel with a capacitor. During the initial period of the recovery voltage developed upon current interruption, most of the recovery voltage is applied to the vacuum interrupter. After the instant at which the non-linear resistor represents its constant voltage characteristics, the SF.sub.6 gas-blast interrupter will take the largest portion of the entire voltage increased thereafter.

摘要： A disconnector for a gas insulated switchgear in which the disconnector includes, in a metallic container filled with an insulated gas, a stationary electrode having a contact, a stationary electrode shield electrically connected to the stationary electrode to surround the contact, the stationary electrode shield made of an electrically resistant material and having a free end portion and inner and outer surfaces, and a movable electrode arranged to face the contact and being movable into and out of electrical contact with the contact, and in which the stationary electrode shield is arranged to flow discharging current therethrough due to an interelectrode voltage applied between the stationary electrode and the movable electrode. The disconnector includes an annular metallic electrode coaxially mounted on the free end portion of the stationary electrode shield so as to allow the movable electrode to pass therethrough. The metallic electrode has an exposed surface exposed to the insulated gas and the exposed surface of the metallic electrode is adapted to be larger in field strength than the inner and outer surfaces of the stationary electrode shield for producing the discharge between the exposed surface of the metallic electrode and the movable electrode.

摘要： A series circuit of a gap section and a valve block is connected between a transmission line and the ground. The valve block consists of a plurality of nonlinear resistor elements connected in series. A first impedance circuit consisting of a resistor and a capacitor connected in series is connected in parallel to the gap section. Also, a second impedance circuit consisting of another resistor and another capacitor connected in parallel is connected in parallel to the valve block. The ratio of the voltage applied across the gap section to that applied across the valve block is determined by the ratio of the impedance of the first impedance circuit to that of the second impedance circuit. A pair of discharge electrodes included in the gap section, which are a prescribed distance apart from each other, comprise a narrower gap region at which spark is started.
