GIS bellow expansion joint structure improvement

Abstract

Abstract:

Abstract:Bellow expansion joint structure was improved and compared with original structure under finite element analysis. The result indicated that stress and axial deformation of improved structure was significantly reduced, deformation difference of expansion joint center and margin was reduced, bending moment on bolt was reduced. After improvement, equipment could resist exterior force more effectively, and bear stronger deflection. Thus, bellow expansion structure improvement could effectively resist exterior force, reduce deflection, and ultimately ensure the operating safety and stability of GIS.
