Abstract SF6 gas leakage in a 220kV gas-insulated switchgear bellows caused by the deficient handing of the riveting process is described. The terrible riveting process results in multiple site gas leakage around the bellows. This paper analyzes the live detection and power-off maintenance process of the defect. Comprehensive analysis of the fault cause is taken based on the operating experience and field investigation. Finally, a series of prevention measures are proposed as a guide and reference for similar defect processing.
