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
