Abstract

As an important part of the power grid, the safe and reliable operation of overhead transmission lines is of great significance. In order to ensure the reliability and continuity of power supply in power grid, the overhaul mode of live-line work is usually adopted. At present, there is little research on live-line work of overhead transmission line overhaul arrester at home and abroad. In order to ensure the safety of live-line work operators, this paper models and simulates live-line work of overhauling surge arrester with support clearance in 500 kV cup-type-tower. The distribution of electric field on the surface of live-line work operators under this line structure is calculated and analyzed, which can provide reference for the personal safety of live-line work operators.
