超、特高压直流线路覆冰监测装置典型故障分析

Analysis of Typical Faults of Ice Covering Monitoring Devices for Extra High Voltage and Ultra High Voltage Direct Current Lines

针对超、特高压直流线路覆冰监测装置典型故障,统计了某输电公司超、特高压直流输电线路覆冰在线监测装置典型问题,结合检修工作经验,分析了覆冰监测装置通信中断故障、传感器故障、蓄电池故障、摄像机图传黑屏故障等特点,提出了加强覆冰监测装置后台系统数据管理、硬件设备的检修维护、优化通信卡网络升级等建议。

Aiming at the typical faults of icing monitoring devices for extra high voltage and ultra high voltage direct current transmission lines, the typical problems of ice covering monitoring devices for extra high voltage and ultra high voltage direct current transmission lines of a transmission company are counted. Combined with the maintenance experience, the characteristics of communication interruption fault, sensor fault, battery fault and camera figure transmission black screen fault of icing monitoring device are analyzed. Some suggestions are put forward, such as strengthening the data management of background system of icing monitoring device, overhaul and maintenance of hardware equipment, optimizing communication card network upgrade and so on.
