摘要： A DC circuit breaking device is provided for interrupting the transmission of direct currents to an electric power system by making external changes to an arc generated upon contacting or separation of contacts 11 and 12 in order to rapidly extend and vibrate arc currents. In a self-excited commuting DC circuit breaking device, coils 41 and 42 opposed to a fixed and a movable contact 11 and 12, respectively, are disposed around the outer circumferences of the contacts 11 and 12, and currents flowing through a commutation circuit or the contacts 11 and 12 are allowed to flow through the opposed coils 41 and 42 so as to apply magnetic fields to the neighborhood of an arc. This constitution provides the DC circuit breaking device with high performance that it can rapidly extend and vibrate arc currents to thereby interrupt direct currents.

摘要： A method for recovering a condensable gas from a mixed gas uses a condensable gas recovering apparatus. The apparatus comprises a compressor for compressing a mixed gas comprising a condensable gas and an incondensable gas, a mixed gas separator including a cooler and an adsorbent that adsorbs the incondensable gas, and a vacuum exhauster. The method comprises the steps of introducing the mixed gas highly compressed by the compressor into the mixed gas separator, liquefying and recovering the condensable gas by cooling the mixed gas separator with the cooler while the adsorbent adsorbs the incondensable gas contained in the mixed gas in a high pressure state, and exhausting the incondensable gas from the adsorbent in a low pressure state where the gas in the mixed gas separator has been exhausted by the vacuum exhauster. Therefore, recovery of the condensable gas is carried out with high reliability, and mixing of a large quantity of the condensable gas into the incondensable gas is easily prevented.

摘要： A small-sized arrangement for a DC circuit breaker with a reactor and a capacitor connected in series is provided which includes a DC circuit breaker, a parallel impedance means with a suitably determined inductance and a suitable capacitance less in value than the inductance, and an energy-absorbing element. The parallel impedance means has a parallel reactor of a carefully selected inductance and a parallel capacitor of a smaller capacitance value. Determining the inductance and capacitance values of the parallel reactors and parallel capacitors employed in the parallel impedance means to satisfy a certain condition defined by specific formulas can cause the DC circuit breaker to take full advantage of the inherent performance thereof while allowing the interruption time to remain minimized, thereby achieving enhanced interruption performance. Since the capacitance of the parallel capacitor is rendered relatively smaller, the device can be small in size and low in cost.
