Abstract
The electric field distribution in 550 kV disconnector of GIS was investigated by using the Finite Element Method
in this paper.And the optimization of electric field distribution in 550 kV disconnector was attained
based on the Response Surface Method and the Finite Element Method.The results revealed that a uniform electric field distribution is achievable in 550 kV disconnector of GIS.The conclusion was attained that power frequency withstand voltage of 740 kV for 1 minute
lightning impulse of 1 675 kV
and switching impulse of 1 300 kV meet the requirements of the national standard.The structure design and the reliability of the optimized disconnector were improved.
