Abstract

The 1100 kV GIS disconnector is the electrical equipment which was used in the 1000 kV UHV AC testing demonstration pilot project. Based on two different kinds of structures, three dimensional electric field of 1100 kV SF6 disconnector airchamer are analyzed by using the finite element software. For the complex Analysis the extra-high voltage disconnector airchamer, its volume is big and the structure is complex, applies in the different line situation. By analyzing the electrical field intensity distribution of disconnector airchamber, the distribution nephogram of the whole area and the maximal electric field intensity area are attained and the comparisons between two distributions are done. Then theoretical basis for construction design of disconnector is supplied according to the analyzed results of electrical field.
