摘要
随着经济的发展,城市配电网络以及山区高压电缆架设工程进展迅速。但是由于部分地区的自然灾害、人为事故频繁等原因,电力线路经常出现故障。比如雷电活动导致的跳闸现象。对此,本文作者通过对220k V某线雷击跳闸故障进行实例分析,寻找跳闸事故的原因。并结合多年工作经验对事故之后的改进措施提出了自己的看法。
With economic development,urban and mountain high voltage cable distribution network set up is progressing rapidly.However,in some areas due to natural disasters,man-made accidents and other causes of frequent power lines often faulty.Such as tripping caused by lightning activity.In this regard,the author through a 220kV Transmission Line Lightning instance failure analysis,looking for reasons tripping accidents.Combined with years of experience on the improvements made after the accident his views.
