ZN82-12真空断路器Detailed product description:Column tabs
ZN82-12真空断路器采用世界上先进的小型化,高功能灭弧室制造技术。触头用低截流水平的铜铬合金,截流小(3.5A以下),操作过电压小于2.0倍。触头部形状刻意加工,31.5kA以下采用纵向旋转磁场灭弧,40kA以上采用横向旋转磁场灭弧,可防止触头表面局部过热,减少触头磨损,延长触头寿命,额定短路电流开断次数不少于100次。

ZN82-12真空断路器配用电动机弹簧式操动机构,交直流电源两用,操作电流小,弹簧储能时间小于5s,适合于频繁操作场合。

操动机构与主开关本体配置合理,机械性能稳定可靠,弹跳小于2ms,机械寿命达3万次。

断路器辅助功能完备:自带防跳功能和低电压电容脱扣器,辅助开关多达三付,预留接点多,可作备用。二次触头接点有64对,且与手车位置有可靠的机械联锁,同时,控制电源交、直流均可,适应性强。 

40kA的真空断路器,由于灭弧室设计结构先进,制造精良,仍具有快速重合闸功能(O-0.3S-CO-180S-CO)。
