Abstract

The structure of double circuit transposition tower in 1000 kV ultra-high voltage (UHV) AC transmission lines is complex and it has various types of jumper. The electric field distribution on the surface of jumper is higher and more uneven when compared to ordinary tension tower. With three dimensional finite element method (FEM) and harmonic analysis, the electric field distribution on the surface of jumper was calculated when considering the effect of tower, fittings, insulator strings and phase influence, the regularity of electric field distribution on jumper were researched and the jumper that didn´t meet the electric field standard was optimized. The achievements obtained in this paper will be used in UHV project and relieve the problem of audible noise and radio and television interference.
