气体分解产物之间的关系。

Abstract

HV circuit breaker with SF

gas as the arc extinguishing medium is used widely in the system at 220 kV and above in China.After interrupting short circuit current

in the arc interrupter will decompose and producesuch gases as SO

and SOF

which have an impact on the interruption performance of circuit breaker.Inthis paper

short-circuit breaking tests are carried out on a number of HV circuit breakers and the gas inside the cir-cuit breakers is detected.The relationship between circuit breakers with different voltages and different short-cir-cuit test modes and SF

gas decomposition products is stu

died.
