Gas pressure in puffer chamber and nozzle throat is measured for a high-voltage SF6 circuit breaker without load
and the pressure characteristic curves of the puffer chamber and nozzle throat are obtained in a test.The relationship between pressure and breaking time is analyzed.The changes of the pressure in puffer chamber and nozzle throat under different base pressure are compared
which shows that base pressure has an influence on the pressure in gas chamber.
