Abstract: The basin-type insulator as the core component in gas-insulated switchgear (GIS), its insulation design affects insulation level of entire GIS.This paper expounded the design thought of basin-type insulator and analyzed its structural style. Combining with the electric field and manufacturing process, this paper gave the optimal shape proportion and proposed the electric field check criterion of the key location in the design process of basin-type insulator. The test verified the rationality of proposed check criterion.
Key words: basin-type insulator; insulation design; lightning impulse voltage
