| 摘 要： | 阐述了断路器过电流分断能力试验程序。根据过载、额定极限短路分断能力Icu和额定运行短路分断能力Ics试验程序的差异对过电流保护操作情况下的供电连续性进行了分析,提出了断路器Icu等于Ics、故障类型指示、故障记录、触头磨损指示等功能对提高供电可靠性和连续性的作用。

| Abstract: | The test procedures of overcurrent break capacity of circuit breaker were presented. The electricity supply continuity under the condition of overcurrent protection was analyzed based on the differences of over load current, limit Icu , rated run Ics breaking capacity test procedure. As a conclusion, Icu equals Ics, fault type indication function ,fault recording function and contact wearing indication etc. are useful to make good electricity supply continuity. |
