Abstract: The reliability of basin insulator is critical to the safe operation of complete Gas-Iinsulated Metal-Enclosed Switchgear(GIS) as well as the power grid. In this paper, taking the basin insulator used in 800 kV GIS as an example, the structural design of the basin insulator was comprehensively considered from the aspects of shape, shielding ring and center inset, etc, the insulation and mechanical properties of key parts were simulated calculated by finite element analysis software, the calculation results meet the criterion requirements, also the feasibility of the design was verified by type test.
Key words: gas-insulated metal-enclosed switchgear; basin insulator; mechanical design; insulation property; mechanical property
