    摘要: The high-voltage circuit breaker with gas insulation is equipped with a device for gas-blast and blowout of the arc generated between the stationary arcing contact and the movable arcing contact when the current is interrupted. Downstream from the blowout nozzle there is located a cooling tube provided with several holes for flow of the gas placed on the outlet path of the hot gas generated by the arc. When the hot gas flows in the cooling tube, the gas pressure difference at the level of the outlet holes causes cool gas to be sucked into the tube and gives rise to a mixture of the hot and cold gases. The gas outlet to the outside of the cooling tube is sufficiently cooled to ensure the dielectric characteristics of the circuit breaker.

    摘要: A method of locating a fault point in a parallel two-circuit transmission line in an n-terminal system. When a single fault occurs at one place in one circuit of the transmission line and when a multiple fault occurs at the same place in the two circuits, a distance to the fault may be calculated by the method of this invention. The method comprises the steps of transforming the transmission line into a T three-terminal parallel two-circuit transmission line circuit having three branches, calculating a value representing a length of one of the three branches on the basis of differential currents flowing into the branch points of the transmission line, determining if that value represents the distance from a terminal connected to the branch point to the fault point, employing the value as the distance to the fault point if the value represents such a distance, repeating the value calculation and determination for the other two branches if the value does not represent the distance to the fault, determining a next branch point for which to perform equivalent transformation with respect to, and repeating the previous steps until the fault is found.
