Since the power supply to the switch is cut off, the interlocking switch RyX is switched, and the common contact C1 and the switching contact B1 are connected, and the common contact C2 and the switching contact B2 are respectively connected. As a result, the carrier signal from the master station (not shown) provided in the load side substation or the like is hardly attenuated via the coupler 14F and the slave station 30.
It is directly transmitted to the carrier circuit of A.

Is directly transmitted to the carrier circuit.
The pseudo resistor R is for preventing the impedance of the coupler on the unused side from becoming a low impedance in the carrier frequency band when viewed from the carrier side, thereby preventing leakage of the carrier signal. ing.

The carrier circuit 303 demodulates the carrier signal from the coupler 301D or 301F that has passed through the detector 303, and converts it into a digital signal. The logic unit 304 performs the sign verification of the digital signal sent from the carrier circuit 303, the address determination of its own station (slave station), etc., and operates the switch controller 305 to control the switch 11 to open and close.

勿論可能である。In the above description, the case where the carrier signal from the master station is received by the slave station has been mainly described. However, since the carrier circuit and the coupler (coupling unit) have the same configuration, the slave station side is the same. The transmission and reception of the carrier signal from the master station to the master station side is naturally possible according to the same principle.

When a coupler is connected to each of the U, V, and W phases in the master station, the slave station can transmit and receive carrier signals in only three phases, or one phase or two phases, so zero phase voltage is applied. Capacitors connected to the distribution line may be selectively used depending on the distribution line carrying function such as detection and phase detection.

現することができる。As described above, according to the present invention, as in the conventional case, the carrier signal received at the slave station is branched, the attenuation is caused by the resistance of the closed circuit for resonance, and the attenuation is caused by the coupler on the side opposite to the carrier. Since the carrier signal that has passed through the coupler is directly transmitted to the carrier circuit without the above, the carrier signal can be transmitted and received accurately, and the accuracy of the opening and closing control of the switch and the state monitoring can be improved. Further, since the circuit configuration is simple, it can be realized at low cost.
