In this way, this paper gives us stand-by power switch's three different using logics and block condition. Finally, it gives us the calculation of the automatic stand-by power switch's setting time. 比较过程中.给出了三种备自投方式的使用逻辑以及闭锁条件.最后给出备自投断路器时间整定方面的计算。
Water solubilization, the relation between its volume and E%, and the effect of stand-by time on the results of measurement etc. are appraised. 同时对其最大溶水量和它的体积与E%关系以及放置时间对测定结果的影响等性能进行了评价。
