| 摘 要： | 针对消防风机的本级保护断路器以及上一级保护断路器的整定问题进行了探讨。通过实例,指出消防风机的本级保护断路器只设短路保护,而上一级保护器需设过负荷保护,以期为类似消防风机设计提供参考。

| Abstract: | The setting problems of corresponding-level protection circuit breaker and the upper-level protection circuit breaker were discussed in a fire fighting blower.Through an instance,it pointed out that the corresponding-level protection circuit breaker only need the short circuit protection setting,and the upper-level protection circuit breaker need the load protection.It could provide references for the designs of similar fire fighting blowers. |
