工作原理Working principle
FSB-1S卡式电表专用开关FSB-1S-40A 2P
使用时通过信号输入端口给断路器智能分厉脱扣器极加上控制电压，即信号电压(可由远端控制线路提供)，然后将断路器手柄推向闭合位置，通过操作机构带动动触头向静触头运行并与静触头可靠接触，并接通线路。当线路发生过载故障时，过载电流使热双金属元件弯曲，过载脱扣器动作，推动锁定机构复位，从而实现分断线路。当线路发生短路故障时，短路电流使瞬时脱扣器动作，推动锁定机构复位，实现分断线路。当因为某种需要，必须立即切断线路时，可能通过无线控制系统断开控制电压，此时信号电压检测电路得到信号后，对分励线圈输出电压信号，推动整个分励线圈动作，并同时带动锁定机构复位，实现分断功能。因此，该产品不同的线路状态下，均能达到分断的目的.
