Abstract

800 kV high voltage AC disconnector is an important switchgear equipment of 750 kV transmission line in Northwest power grid of China.In this paper

the theoretical analysis and researches on 800 kV high-voltage AC disconnector are performed further on the basis of researches of high voltage switchgears both at home and abroad.The technical scheme and structural parameters of the 800 kV high voltage disconnector are defined.The three-dimensional model of the 800 kV high voltage AC disconnector is set up and the mechanical and dielectric characteristic simulation analysis is performed.The prototype of 800 kV high voltage AC disconnector has been developed and the type test has been verified.It is concluded by the simulation analysis and type test that the designed 800 kV high voltage AC disconnector

which is mentioned in this paper

has reasonable structure and its mechanical and dielectric performance meet the tendering requirement

which has important guiding significance for the research and development of other subsequent series disconnectors.
