摘　　要：为明确带避雷器超高压双回线路带电作业安全防护措施的技术要求,分析了带避雷器500 kV ZST3型塔带电作业人员体表场强,研究了屏蔽服的屏蔽效率要求。结果表明,避雷器不同安装方式模型中人体体表场强的最大值均出现在手部和头部;避雷器安装在横担时对人体头部和手部电场的影响范围与程度最大;穿戴屏蔽效率60 dB的屏蔽服,能满足带电作业的要求。In order to clarify the technical requirements of safety protection measures for live working on ultra-high voltage double circuit lines with arresters,the present work studied the body surface field strength of the lineman on 500 kV ZST3 tower with arresters,and analyzes the shielding efficiency requirements of shielding suits.The results showed that the maximum values of the body surface field strength in models with different installation modes of the arrester are found near the hands and head.When the arresters are installed on the cross-burden,the range and degree of influence on the electric field of the human head and hands are the greatest.Wearing a shielding suit with shielding efficiency of 60 dB can satisfy the requirements of the live working.
