摘　　要：为了验证1000kV交流输电线路带电作业技术研究成果,并为1000kV试验示范工程开展带电作业提供实践经验,在1000kV交流特高压试验基地试验线段上进行了带电作业现场应用试验。试验对1000kV带电作业最小安全距离、最小组合间隙、绝缘工具最小有效绝缘长度、安全防护、电位转移等技术要求进行了现场应用试验研究。结果表明1000kV特高压交流输电线路开展带电作业是安全、可行的,1000kV交流输电线路带电作业技术的研究成果能有效指导带电作业的安全开展。In order to verify the research achievements in the technology of live working on 1,000 kV AC transmission line and to provide practical experience for live working of the 1,000 kV Demonstration Project, an on-site application test on live working was conducted on the test lines of the 1,000 kV UHV AC Test Base. The on-site application and verification of technical requirements on 1,000 kV live working, such as minimum safety distance, minimum complex gap, minimum effective insulation length of tools, safety protection, shift of potential and etc, were analyzed in the test. The test result shows that live working on 1,000 kV UHV AC transmission line is safe and feasible, and the research achievements in the technology of live working on 1,000 kV AC transmission line can effectively direct safe implementation of live working.
