摘　　要：输电线路在线监测装置可用率低的现状已对电网监测系统可靠运行造成了一定的威胁,因此,通过收集各类输电线路在线监测装置的运行情况资料,深入分析故障原因,从供电电源和运维质量两方面提出了提高输电线路在线监测装置可靠性的措施,并对输电线路在线监测装置的寿命要求及使用条件进行了可靠性评价。Low available ratio of on-line monitoring devices of transmission lines has threatened the reliable operation of grid monitoring system. Therefore, by collecting operation information of various types of on-line monitoring devices of transmission lines, this paper makes an in-depth analysis on failure causes and proposes technology to improve the reliability of on-line monitoring device of transmission line from aspects of power supply source and operation and maintenance quality; furthermore, it makes reliability evaluation on the lifetime requirements and service condition of on-line monitoring devices of transmission lines.
