Method And Application Research Of Live-working On Double-circuit Transmission Line

Live-working is an efficient way to reduce the repair time when there is a power failure and improve the reliability of power supply. This paper states the principle of Live-working,on the basis of a numerical method to calculate the electric field intensity of EHV transmission line near tower ,combining the typical tower of double-circuit transmission line, part of Yifengjiayi Line, it analyzes the theoretical calculation and actual data of the electric field intensity, discusses the safe path of various kinds of live-working forms using on the tower which type is SZ₁ and SJ₁, discusses the safe distance on the same tower, and estimates the security of these methods, then forms various live-working programs.
