Abstract
In order to optimize power system in China
it is essential to develop strong and smart UHV and EHV power grid. The development of 550 kV 6 300 A GIS can greatly improve transmission capability of 500 kV lines and decrease the number of power feeding hallway. In this paper
the technical parameters of the new type 550 kV 6 300 A GIS developed by New Northeast Electric Group are described
and the unique characters of its conduction structure are introduced. The electric field distributions of its circuit breaker and disconnector are simulated
and the results verify their insulation performances. The structures and principles of this new type 550 kV 6 300 A GIS have received patent protection in China.
