Abstract: This paper carried out 0.5g seismic acceleration level simulation calculation for the composite insulator casing entirety in 1 100 kV gas insulated metal-enclosed switchgear (GIS) and analyzed the strength and frequency of the casing assembly barrel body, bracket and composite insulator, finding out the weak parts and optimizing them. The calculation and true type test of composite insulator casing show that the 1 100 kV composite insulator casing in GIS reaches the 9 stage intensity seismic standard in domestic ultra-high (UHV) voltage GIS, to provide technical references for the design of other UHV products in the area with high earthquake intensity.
Key words: gas insulated metal-enclosed switchgear; composite insulator casing; 9 stage intensity
