【成興電氣】分段器自動跌落分閘必需具備三個條件 

　　第一、故障電流超過整定的額定啟動電流值；

　　第二、計數(shù)次數(shù)達(dá)到整定值(1、2、3、4次)；

　　第三、線路失壓，線路電流低于300 mA，三者缺一不可，才能自動分閘。

　　First, the faults current exceeds presetting pickup current.

　　Next, the counting time reaches presetting value (1, 2, 3 or 4).

　　Third, the circuit loses voltage and the current is lower than 300mA. And then the Sectionlizer will trip automatically when the aforesaid conditions occur simultaneously. If any of aforesaid conditions doesn’t occur, the Sectionlaizer will not trip automatically.
