摘要： PURPOSE:To lower the number of power stoppages of the distribution system, and lighten the damage of the distribution line by a fault current by opening or making a thyristor type high-speed switch, prior to the opening operation of the breaker in s substation. CONSTITUTION:For a current sensor 8, if an abnormal current by thrunder surge occurs in the distribution line 3 and it reaches shortcircuit fault or the like, the judging means 12 detects the zero phase current, etc., at the same time with the current change of each phase, and inputs the signal of the line shortcircuit fault into a command circuit 13. The command circuit 13 transmits a trigger signal to the thyristor type high-speed switch (OC) 11 through a signal line 9a, and OC 11 finishes a series of operation of closing itself and opening itself again in a short time, and interrupts an arc current. The breaker in the substation is set to the waiting time for approximately 0.2sec from accident occurrence to opening, so by finishing the making and opening of the OC 11 in this while, the arc current is extinguished. In the substation, the fault current vanishes, and the opening operation of the breaker stops, and the power stoppage of the system is avoided.

摘要： PURPOSE:To maintain an uninterrupted state in other sound sections of a distribution line and to sustain power supply by opening the automatic switch in one section of the distribution line, where a ground fault has occurred, upon elapse of a predetermined time which is shorter than an open delay time. CONSTITUTION:When the count of a counter 13 reaches a predetermined count (0.2sec.) after occurrence of ground fault in a distribution line, a NOR gate 17 detects that the distribution line is not shortcircuited and if an open command signal SG12 has been fed from an open command means, i.e., a slave station signal unit 19, an open delay circuit is tripped and an automatic switch 1 is opened temporarily (upon elapse of 0.1sec.). When another normal open automatic switch 1 arranged at a lower position in the faulty section is closed, power is interrupted only for the faulty section and can be supplied continuously for other sound sections of the distribution line.

摘要： PURPOSE:To measure the current of a line with high accuracy, by allowing an AC current to flow to an LED from a line conductor by a current transformer and providing a DC current blocking condenser and an AC current blocking reactor or resistor to the output terminal of the LED. CONSTITUTION:The secondary current of a current transformer CT is transformed by an insulating transformer TR to be supplied to an LED through a thermistor ST. The AC current outputted from the current transformer CT receives full-wave rectification by a rectifying circuit 2 and subsequently smoothed by a smoothing condenser C1 to flow to a constant current diode CRD through a diode D1 and a constant DC bias current is applied to the LED from the diode CRD. As a result, the LED emits light even by a weak current and, by applying the bias current, the linearity of the intensity of emitted light is improved in such a case that a change is generated in the current flowing to the LED and, therefore, measuring accuracy can be enhanced.

摘要： PURPOSE:To relay communication with power consumers and to transmit information smoothly to business offices of power companies by locating a signal relay unit, for controlling communication between a load arranged on a distribution line and an external communication line arranged between slave stations, in the slave station. CONSTITUTION:When an information center 11 communicates with a load consumer in a slave station, a command contact 10a in a master station 1 closes upon receiving a communication command signal from the information center 11 thus connecting the information center 11 and the master station 1. Consequently, an interlocked communication command circuit 21 in a signal relay unit 20 at a commanded slave station closes its command contact 21a thus begining communication between the master station 1 and an external communication line 22 in response to the information center 11. Load information of a power consumer is carried on the external communication line 22 to an optical communication unit 14 through a controller 16. That signal is converted through an LED 1 into an optical signal which 15 transmitted on an optical signal line 3 to the next slave station thence received by the master station 1 thus establishing communication between the information center 11 and the load at a power consumer through a communication command circuit 10.
