Study on Safety Protection of Live Working on Ultra-high Voltage Double Circuit Lines with Arresters
In order to clarify the technical requirements of safety protection measures for live working on ultra-high volt-age 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 e-lectric 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.
