Studies on the Thermal Re-ignition in SF6 High-Voltage Circuit-Breakers by means of Coupled Simulation

Résumé

The paper presents a modelling approach to study the switching capacity of SF6 high-voltage circuit breakers with respect to the thermal re-ignition. This approach is based on the coupling of a model for the thermal re-ignition and a model describing the transient response of an external circuit. It is pointed out that the switching capacity can be evaluated taking into account the simulated trends for the transient recovery voltage similar to the approach in real tests. The different behaviour of the regarded SF6 self- blast circuit-breaker at different arcing times is highlighted using simulation results for pressure, temperature and electrical conductivity.
