针对宁东—山东±660 kV直流输电工程带电作业需要，通过对带电作业人员体表场强和电位转移时流过人体的能量的仿真计算，提出了±660 kV直流输电线路带电作业安全防护要求、屏蔽服的主要参数要求。所得结论可以为±660 kV直流输电线路开展带电作业提供依据和技术支撑。

According to the demand on live-wire operation for Ningdong-Shandong ±660 kV DC transmission project, simulative calculation for human-body under live-wire operation is carried out. Therefore, the safety protection requirement and the main parameters of screening clothing are suggested. The research results could provide technical support for future live-sire operation on ±660 kV DC transmission line.
