| Abstract: | Based on a physical model of arc at the nozzle and the First Law of Thermaldynamics .a calculating method of temperature and pressure characteristics in a SF6 puffer chamber is derived when the nozzle is clogged. A comparison is made between the calculated pressure characteristics on interrupting current of ELF SL type SF6 GCB and the measured ones gained from Baden test station in Switzerland, showing that they are in good agreement. |
