工区里在提1965年线路大修计划的时候,我们工区的北郊保线站提出,要把郊区的一条35千伏线路中的一大段铜导线(13档×3)换掉。理由是,这一段线路曾是污秽区,“发现导线上有腐蚀坑”,前几年还出过一次闪络事故,加上已经运行30多年了,线路导线太老, In the work area, when referring to the line overhaul plan of 1965, the Beijiao Boluo Station in our work area proposed to replace a large section of copper wire (13 files × 3) in a 35 kV suburb. The reason is that this section of the route was once a dirty area. “There was a corrosion pit on the lead wire.” A flashover incident was also reported in previous years. In addition, it has been in operation for more than 30 years and leads in the wire are too old.
