Analysis and Thoughts on a 500kV H-GIS Equipment Failure

Abstract:

Analysis the 500kV H-GIS equipment failure, determine for the circuit breaker chamber internal discharge fault according to the protection action and the use of the analysis of SF₆ gas composition, a detailed analysis of the possible causes of failures, and according to the disintegration test results, to confirm the final reason for internal foreign bodies caused by discharge. Finally, put forward some prevention measures and suggestions for the accident.
