摘要
Abstract
The Ganzi-Tianfu South 1 000 kV line of the Sichuan-Chongqing AC UHV project is China's first 1 000 kV AC UHV line located in a high-altitude and extremely heavy icing area.To ensure safe operation without affecting power supply,it is necessary to carry out non-power-off ground wire de-icing for the Mount Erlang and Mount Zhugang sections with extremely heavy icing.Considering the de-icing requirements of the line and the convenience of wiring,a de-icing interconnection line needs to be designed for power supply.Drawing on previous experience in high-voltage line de-icing design,through calculation and research,the design technical scheme for the voltage level,conductor,insulator string,ground clearance,and transmission tower of the ground wire de-icing interconnection line has been obtained,providing reference and experience for future non-power-off ground wire de-icing of more UHV lines in heavy icing areas.关键词
