Reliability of Complete Gas-Insulated Switchgear
Accident rate of complete switchgears with gas-insulated switchgear (GIS) is considered. The statistical sample covered 30 110 – 500 kV switchgears in a vast region of the European part of the country for the period 2008 – 2022. Their design features and technical characteristics are given. Major and minor failures of GIS, including their structure, namely, distribution on elements of installations, technical and organizational reasons of occurrence, dependence on year of operation are subjected to analysis. The flow parameter (frequency) of GIS failures is determined, as well as the maximum possible time of GIS restoration after damage to the arc suppression chamber of the pole of the 500 kV circuit breaker. Comparative data with failure rate of GIS abroad and with gas-insulated circuit breaker cells in open switchgears are given.
