して成る３相電力線搬送制御装置。A transmitter and a receiver that transmit and receive control signals by power line carrier in synchronization with a predetermined phase of the power supply frequency are connected to any phase of the 3-phase power line, and the phase relationship of the 3-phase power supply frequency between the transmitter and receiver is shown. In a three-phase power line carrier control device that sends a three-phase synchronization signal from a transmitter to a receiver, then sends a control signal, and repeats sending these signals multiple times, the timing for starting signal transmission is set. The output of the transmission signal control section operates the 3-phase synchronous signal generation section, and the 3-phase synchronous signal generation section generates a 3-phase synchronous signal and a timing signal indicating the end of generation of the 3-phase synchronous signal. The control signal generating section is configured to operate, and a switching input for single-phase and three-phase is provided to cut off the output of the three-phase synchronous signal from the three-phase synchronous signal generating section when the single-phase signal is set. and a three-phase power line transport control device configured to operate a control signal generation unit at the output timing of the transmission signal control unit by switching with the timing signal.
