    摘要: There is provided a reclosing system for a power transmission line, which performs high-speed reclosing using protection relays. The protection relays are provided at different terminals of the power transmission line. Each of the protection relays is configured to send the reclosing command to the circuit breaker when a line voltage at the phase with the accident, detected by the metering voltage transformer after the phase with the accident is cut off, falls within an allowable range. The allowable range is determined based on a line voltage assumed at the phase when the phase is normal.

    摘要: A bus-bar protection relay equipment includes a data-acquisition means, a check zone protection means, a fault bus-bar judging means, and a tripping bus-bar judging means. A data-acquisition means transforms analog current signal from the current transformer connected to the bus-bar with two or more dependency regions into digital data at every predetermined cycle. The check zone protection means computes amount Id (vector sum) of operation, and the amount Ir (scalar sum) of inhibition using the digital data transformed by this data-acquisition means. The check zone protection means transforms analog current from the current transformer of a line segment into digital data “n” multiplied with. The amount Id of operation and the amount Ir of inhibition are computed. An actuating signal is outputted when predetermined relationship is satisfied by using the amounts Id and Ir. The fault of the internal and the external to the area which included the computed value two or more dependency regions by a predetermined a percentage differential protection calculation is judged. A fault bus-bar judging means 13 performs a fault bus-bar judging by two or more above-mentioned dependency regions using the operating quantity which computed the operating quantity and computed it in the operating quantity and the check zone protection means which were computed.

    摘要: An electrostatic recording head has a plurality of electrode wires arranged parallel to each other at a predetermined pitch to form recording electrodes at one ends thereof, control electrodes arranged along these recording electrodes, and a recording electrode retainer for integrally fixing these electrodes with a resin. The other ends of these electrode wires are integrally fixed by an electrode wire terminal end retainer of a resin. The electrode wires are electrically connected to a part of the conductive pattern formed on a printed circuit board interposed between both retainers, and are grouped thereby to form a plurality of recording electrode set conductors. These conductors and lead wires connected to the control electrodes are connected to connector terminals. A recording voltage is applied to the connector terminals.
