| 摘 要： | 文章分析了断路器非全相运行的危害,在断路器非全相运行时,由于电气量不对称会出现负序和零序电流,并产生过电压,使电网的发、供、用电设备受到损害,给电网的安全运行带来了极大的隐患。因此,提出了防止断路器非全相运行的各项预防性措施和在断路器非全相运行时,如何做到正确处理,以避免非全相运行对电力设备的损害。

| Abstract: | The paper analyzed the harm of non-all-phase operation for circuit breaker.Since electrical quantity is asymmetrical during the non-all-phase operation,the negative sequence and zero sequence currents can be arisen,which produces over-voltage to damage electrical equipment in power grid and to bring the maximum hidden trouble for safe operation of power grid.The preventive measures for preventing non-all-phase operation of circuit breaker,and when circuit breaker was in non-all-phase operation mode,how to c... |
