Abstract：
With the wide spread of casting technology in the power industry,more and more small,low cost high pressure vessels emerge.In order to realize the purpose of GIS(Gas Insulation Switchgear)type isolation switch compact design,the design of three-phase common-box isolation switch was completed through the strength analysis of the shell after finite element calculation.The results show that the shell has passed the test of water pressure failure and satisfies the development purpose of compact GIS.
