激光清理高压线路异物

2017-08-08 07:35:21   中国青年网

湖南日报8月7日讯(记者 邹靖方 通讯员 赵向新)今天下午2时,在长沙县黄花镇,湖南送变电工程公司员工首次运用激光异物清理装置,对500千伏鼎星Ⅱ线053号大号侧所悬挂的长条异物进行紧急清除,确保迎峰度夏期间500千伏鼎星Ⅱ线、沙星Ⅰ线两条线路安全稳定运行。

据了解,因500千伏鼎星Ⅱ线和沙星Ⅰ线为世界上第一条垂直排列的紧凑型双回路线路,输送负荷大,供电重要性及常规带电作业有一定安全风险。

国网湖南省电力公司此次采用的激光装置射程可达到150米,作业时间仅10至20分钟,其发射的特定功率和波段的激光,能够有效作用于非金属材质的电网异物,而不被线路金属材质吸收,因此对电网设备毫无损伤,有效保护了电网的安全稳定运行。
