Abstract
Aiming at land resource shortage in Foshan and Jiangmen as well as serious lack of line corridor,the erection of same-tower four-circuit lines can improve transmission capacity of unit corridor,save line corridor.However,the line cou-pling is strengthened.When the line service stops,there is higher electrostatic induction and electromagnetic induction be-tween the operating and non-operating lines.Therefore,the paper calculates induced voltage and current of 500 kV and 220 kV same-tower four-circuit lines between 500 kV Jiangmen converter and Shunde substation transmission lines.It is concluded that the induced voltage and current of 500 kV same-tower and 220 kV lines all exceed the rated parameter of class B grounding switch;induction value of 220 kV Shunji line exceeds that of 500 kV converter line.It is therefore suggested trans-forming grounding switch of relevant substations.关键词
