る通信ケーブル断線区間検知装置。 1 of the empty lines of communication cables laid or erected
While using the line, the line is divided into one area or the entire area of the communication cable into at least one or more areas to be monitored, and the monitored area is divided into one or more areas to be monitored, and the monitored area is divided into at least one area or the entire area of the communication cable. A resistor is provided between the pair of lines of the above line at the proximal end and distal end of the area as well as at the boundary between adjacent monitored sections, and a resistor is provided between the pair of lines of the above line at the proximal end of the line in the monitored area. When the generated voltage value between the DC constant current power supply that flows a constant value of DC current and the above line is compared with the reference voltage value set in advance for each monitored section, and the generated voltage value becomes larger than the reference voltage value. A communication cable disconnection section detection device, characterized in that a comparison detection means for detecting this is provided.
