X-ray Digital Imaging Detection and Analysis of Gas-Insulated Switchgear Busbar
The operational reliability of Gas-Insulated Switchgear(GIS)Which is a key equipment in substations,is crucial to the safety of power systems.A special inspection was conducted for a 220 kV substation,where a bus-bar fault on the 220 kV side,caused by flood damage,resulted in the busbar disconnection.X-ray digital imaging technology was used to inspect a total of 37 busbar joints,revealing that 3 joints were misaligned and required dis-assembly and reinstallation.Based on the current operational status of GIS equipment,targeted measures are pro-posed for both the manufacturing and installation phases and the operation and maintenance phases of GIS equip-ment,to improve the commissioning quality and ensure the safety of the power grid.
