The fiber composite carbon fiber conductor operating temperature stress monitoring system comprises an optical fiber composite carbon fiber conductor, a monitoring front end, a monitoring management platform, a monitoring client, an optical fiber patch cord, a photoelectric separator and connection accessories. The monitoring front end can monitor the temperature distribution situation of each section of the optical fiber composite carbon fiber conductor in the monitoring range of the monitoring front end in real time, and the temperature distribution situations can be output to the monitoring management platform and the monitoring client in the form of a temperature spectrum curve in the length direction of the optical fiber composite carbon fiber conductor. Based on the information, the power grid can know the current-carrying margin and health status of each section of lines, and the defectsof the optical fiber composite carbon fiber conductor are troubleshot, so that the intelligent dispatching of transmission routes is realized. According to the optical fiber composite carbon fiber conductor operating temperature stress monitoring system and the monitoring method thereof, reliable monitoring information is provided to the power grid monitoring and dispatching personnel, and comprehensive understand the health status and the current-carrying margin of the lines is facilitated.

Description

technical field [0001] The invention relates to an optical fiber composite carbon fiber conductor operating temperature stress monitoring system and a monitoring method thereof, and belongs to the technical field of a smart grid carbon fiber composite core conductor monitoring system and a monitoring method thereof. Background technique [0002] The research on carbon fiber composite core conductors began in the 1990s and was developed by Japanese scholars. In 2004, the United States first applied carbon fiber composite core conductors to power transmission lines. my country's research on carbon fiber composite core conductors began in 2005, and the first application of this conductor in my country was in the expansion and transformation of 220kV lines in Liaoning and Fujian in 2006. Carbon fiber composite core wire has the characteristics of high strength, large carrying capacity, good heat resistance, small linear expansion coefficient, light weight, and good corrosion res...

AI Technical Summary

Problems solved by technology

Since carbon fiber composite core conductors can increase line capacity through high-temperature operation, the current line detection methods cannot monitor and manage the line operating conditions, which limits the development prospects of carbon fiber composite core conductors in the field of high-voltage power transmission and distribution.
