Abstract With the operation of 500kV AC compact lines, the researches on the partial outage maintenance mode of live operation, the mechanical device replacing the operator to enter the electric field at the critical distance to carry out live operation mode research and the related standard formulation of live operation are limited. In this paper, the vertical load and horizontal tension of overhead conductors are calculated and analyzed, and a set of tool for replacing insulators of 500kV double-circuit transmission lines on the same tower is designed. Through checking and analyzing each part of mechanics, it is proved that the design scheme is safe and reliable, and can meet the requirements of operation. Finally, the tool is applied in the field, which proves the practicability of the tool and effectively improves the operation efficiency.
