【Abstract】 A series of experimental investigation on live line work for 750kV transmission line is carried out. The minimum working distance and minimum combinational gap for various types of towers under different overvoltage as well as the minimum effective insulating length of insulating tools are determined. A great variety of insulating tools and screening clothing are developed and their electrical and mechanical properties coincide with requirement of live line work for 750kV transmission line, the corresponding safe guarding measures are revised. The results of this experimental investigation provide technical support and are available for reference to perform live line work for 750kV transmission line.更多还原
