摘要(Abstract)：
随着杭州地区220 kV同塔四回高压输电线路的不断投入运行,线路停电检修工作面临问题日益凸显。通过研究220 kV同塔架设四回输电线路带电作业的安全距离、进入强电场方法、带电作业安全性分析、危险点及预控措施分析等一系列关键问题,探讨了220 kV同塔架设四回输电线路带电作业的可行性。
With 220 kV same-tower-four-circuit HV transmission lines continuously put into operation in Hangzhou, the problems line maintenance by outage faces become increasingly visible. By investigation on safety distance for live work on 220 kV same-tower-four-circuit transmission lines, ways to enter into strong electric field, analysis on safety of live work, dangerous point and precautions, the paper discusses feasibility of live work on 220 kV same-tower-four-circuit transmission lines.
