运用统计学原理统计分析LW6—110 SF6断路器三相联动分闸时间的大量测试数据后给出了该种断路器单相及三相整体分闸时间的置信区间。假设检验三相联动操作时各相分闸时间不同期性的结果表明：三相分闸时间无显著性差异，同期性良好。最后给出了基于概率分布确定断路器额定分闸时间参数的一种方法。

Base on statistical analysis of test data of three phase opening time of LW6-110 SF6 circuit breaker, this paper gives the opening time confident interval of the circuit breaker, and the non-simultaneity is hypothesis tested to three phase opening time. It shows that opening time is no large difference among three phase,in other words, the opening synchronism is good.And it also gives a method of determining rated parameters of circuit breaker opening time by probability distribution.
