Finite Element Analysis of Sealing Structures for SF6 Gas Insulated Switchgear

Abstract:

The sealing equipment of the SF6 GIS including the rubber O-ring and bolts were numerically simulated. Effects of bolts number, the tension moment of bolts, and gas pressure on contact stress and peak stress of O-ring were mainly studied. Simulated results showed that the bolts number and tension moment of bolts has a great effect on the sealing performance of mechanical seal and the maximum stress of O-ring. The higher contact pressure could be achieved under the condition of a larger bolts tension moment and bolts number and smaller gas pressure, but it also results in a reduce of life of O-ring.
