| 摘 要： | 就低压进线断路器选型中的两个实际问题进行了认真分析,提出了低压进线断路器的短路分断能力应按照运行分断能力选择,低压进线断路器在一定条件下可以选用塑壳式断路器取代框架式断路器的观点,可供低压进线断路器设计选型时参考。

| Abstract: | The two practical questions encountered in type selection of low-voltage incoming circuit breaker are analyzed. Author points out that the breaking capacity of short-circuit should be selected according to operational breaking capacity and plastic shelled breaker can be selected to substitute circuit breaker, which provide good references for type selection design of low-voltage incoming circuit breaker. |
