发明名称 DISTRIBUTION LINE CARRIER SYSTEM
摘要 PROBLEM TO BE SOLVED: To prevent a drop of carrier signal receiving level in a carrier circuit at a part of a disconnecting switch on a distribution line. SOLUTION: In a distribution line carrier system composed of coupling devices 7, 8 arranged in front and in the rear of the disconnecting switch 1 connected to distribution lines 2, 3 and the carrier circuit of a remote station 9 connected between the coupling devices 7, 8, the remote station 9 is provided with a pair of two-winding transformers 16, 17, each composed of a single primary winding and double secondary windings. The primary windings of the transformers 16, 17 are connected to the coupling devices 7, 8 respectively. The receiving part is composed of connecting the first secondary winding 16c of the transformer 16 with the first secondary winding 17c of the transformer 17. The transmitting part is composed of connecting the second secondary winding 16b of the transformer 16 with the second secondary winding 17b of the transformer 17.
