摘要
以SF_(6)气体为灭弧介质的高压交流断路器广泛应用于我国220 kV及以上电力系统中,开断短路电流后,灭弧室内SF_(6)会分解产生SO_(2)、CF_(4)、CS_(2)、SOF_(2)等气体,对断路器的开断性能产生影响。文中对多台高压交流断路器开展短路开断试验,对断路器内部气体进行检测,研究了不同电压等级断路器及不同短路试验方式与SF_(6)气体分解产物之间的关系。
HV circuit breaker with SF_(6)gas as the arc extinguishing medium is used widely in the system at 220 kV and above in China.After interrupting short circuit current,SF_(6)in the arc interrupter will decompose and producesuch gases as SO_(2),CF_(4),CS_(2)and SOF_(2),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_(6)gas decomposition products is studied.
