摘要:
为确保±800 kV直流输电线路带电作业的安全可靠,文中结合工程实际,搭建直流输 电线路小转角塔等比例模型,并使用ANSOFT软件对吊篮法和软梯法两种不同作业方式下人体体 表场强的大小进行了计算,分析并得出带电作业人员进出等电位过程中宜推荐的方式和路径, 进而确定了带电作业人员应采取的安全防护措施。结果表明:采用吊篮法进出等电位过程中, 作业人员体表平均场强相比软梯法更小,综合作业方式的劳累程度和可操作性,推荐作业人员 采用吊篮法的方式进出等电位;作业人员进出等电位的过程中应穿戴屏蔽效率为60 dB、配有 金属丝面罩的直流特高压专用屏蔽服。以上结论能为±800 kV直流输电线路小转角塔带电作业 的顺利开展及安全防护措施的制定提供理论依据。
Abstract:
In order to ensure the safe of live working of ±800 kV DC transmission line, combined with the engineering practice, an equal scale model of small angle tower for HVDC transmission lines is constructed. The values of field strength of the body surface in two different operation modes are calculated by using ANSOFT software. The recommended methods and paths in the process of equipotential handling are analyzed and obtained, and then the safety measures should be taken by the electrified operators. The results show that when using a hanging basket for equipotential operation, the average intensity of workers body is smaller than the soft ladder way, according to the degree of fatigue and operability of operation methods, it is recommended that operators use the hanging basket method to enter and exit equipotential; When performing equipotential operation, the operator shall wear a direct current ultra-high voltage shielding shield with a shielding efficiency of 60 dB and a metal wire mask. The above conclusions provide a theoretical basis for the live working on the small angle tower of ±800 kV DC transmission line.
