The paper describes the selection principle of primary schemes for C-GIS and determines the general structure arrangement by comparing different elements and box structure, analyzes the insulating characteristics of SF6 gas and calculates the SF6 gas clearance and along surface insulation. It puts forward the factors that should be considered and strength analysis methods when designing gas chamber structure and analyzes the reasons of influencing the temperature rise of gas chamber and offers the ways of radiating. The vacuum circuit breaker and three-position disconnector are designed for C-GIS and special micro-computer controller for the three-position disconnector is developed. On the basis of new type sensors, suitable control and protection system for C-GIS is suggested. The type test items for C-GIS and its internal elements are introduced to prove that the development is successful.
