System for Power Distribution Network Monitoring and Optical Fiber Composite Power Distribution Cable Thereof

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution monitoring system and a composite optical distribution cable for the same. In the present invention, a signal transmission unit transmits a control signal to a control line to set an optical transmission path to a measurement object section through control of a connection unit, transmits an optical signal through a set optical transmission path, And analyzes the distribution temperature of the measurement target section. According to the present invention, by using the optical composite distribution cable, the distribution temperature is monitored with respect to the distribution distribution section of the distribution grid using the optical fiber of the optical distribution distribution cable while configuring the distribution view, and the optical signal is switched at the branch point connecting the load Optical switches are provided to set optical transmission paths, optical signals are transmitted and received through corresponding optical transmission paths, and distribution temperatures of the respective distribution sections are measured, thereby efficiently and efficiently monitoring the distribution plan having various distribution paths.
