摘要
Abstract
Due to the strong coupling in 500 kV double circuits on single tower,there are higher inductive voltage and inductive currents on the non-energized lines while another line is energized.The 500 kV double circuits from Zhejiang Lanxi Power Plant to Shuanglong Substation is chosen as the object.The magnitude and distribution characteristics of the induced voltage of maintenance line and induced current of grounding wire are simulated.The causes of the ablation of the ground wire are analyzed;and then the corresponding protective measures are proposed.So as to provide reference for the formulation of maintenance program and the selection of temporary grounding wire.关键词
