    摘要： Four sets of a first pair of diodes, a second pair of diodes and a GTO breaker are connected between the power rectifier, the power inverter and four electric car power supply lines arranged in parallel with each other and separated by two dead sections. Therefore, it is possible to cut off powering current and regenerative current simultaneously by simply turning off the GTO breaker. Further, even if a regenerative electric car is running on the electric car power supply lines, it is posible to prevent the occurrence of an arc at the other dead sections due to a potential difference between two power supply lines. Further, in case of powering/regenerative bus bar accident, it is possible to effectively cut off both a regenerative current and an extension power supply current flowing from the power supply lines by the four GTO breakers of a relatively small interrupt capability without exerting the influence of power suspension upon other adjacent substations supplying the extension power supply current.

    摘要翻译： 四组第一对二极管，第二对二极管和GTO断路器连接在电源整流器，电力逆变器和四个电动车电源线之间并联布置并分开两个死区。 因此，可以通过简单地关闭GTO断路器来同时切断供电电流和再生电流。 此外，即使再生电动汽车在电动汽车电源线上行驶，也可以防止由于两个电源线之间的电位差而在其他死区产生电弧。 此外，在供电/再生母线故障的情况下，可以有效地切断由具有相对小的中断能力的四个GTO断路器从电源线流出的再生电流和延长电源电流，而不产生影响 在提供延长电源电流的其他相邻变电站上的电力悬架。

    摘要： A disconnecting switch arrangement for a high voltage disconnecting switch equipped with an earthing device for use particularly in a metal clad insulated substation. The arrangement comprising a disconnecting unit, an earthing unit and an actuating unit for actuating the disconnecting unit and the earthing unit. The disconnecting unit comprises a stationary contact member, a common stationary contact member at a standard spacing from the stationary contact member and a common movable contact member for disconnecting from and connecting with the stationary contact member and the common stationary contact member and is moved in a circular motion by the actuating unit. The earthing unit is comprised by an earthing contact member, the common stationary contact member and the common movable contact member each of which is commonly used with the disconnecting unit.
