关于低压断路器短路分断能力选择的讨论

Discussion on Short-Circuit Breaking Capacity Seletion of LV Circuit Breaker

扼要说明有关低压断路器短路分断能力术语的含义,并重点讨论了如何合理选择低压断路器的短路分断能力,以及如何按实际短路回路的X/R值修正其额定短路分断能力等问题。

Related terminologies of short-circuit breaking rapacity of I,V Circuit Breaker were described to the point. Issues of how to selecting short-circuit breaking capacity of LV Circuit Breaker reasonably and correcting the rated short-circuit breaking capacity based on actual short-circuit X/R were expatiated which can be referred in actual project design.
