【摘要】 由于光纤通信具有容量大、传送信息质量高、传输距离远、性能稳定、防电磁干扰、抗腐蚀能力强等优点,近年来在电力系统得到了广泛的应用。电力系统光纤传输网络运行的可靠性是关系电力安全生产、高效稳定运行的重要保障。但在实际应用中,由于受外力光缆本身质量等多方面因素的影响,光缆很容易遭到破坏从而影响光缆的传输质量。传统的人工加仪器的线路维护方式已经不能适应电力系统对光缆传输性能的分析和管理维护自动化的要求。本文主要介绍了利用OTDR测试技术与GIS地图技术相结合的光缆自动监测系统在北京超高压公司500 kV线路OPGW光缆维护工作中的解决方案。更多还原

【Abstract】 As the optical fiber communication with a large capacity,high-quality transmission of information,transmission distance,stable performance,anti-electromagnetic interference,corrosion resistance,etc.,they has been widely used in recent years in the power system.Power system reliability of optical fiber transmission network is an important guarantee for electricity production safety,high efficiency and stable operation.However,in practical applications,due to the quality of fiber optic cable itself,and many other factors,fiber optic cable is easy to be damaged thus affecting the transmission quality of fiber optic cable.The traditional way of line maintenance with labor and instrument has been unable to meet the requirements of power system in the fiber optic cable transmission performance analysis and automated management and maintenance.This paper describes the use optical automatic monitoring system which combining of OTDR testing technology with GIS mapping technology combining in the OPGW cable maintenance solution in 500kV lines of Beijing EHV Company.更多还原
