WST2-SY1 Eries Of Off-load Strip Tap Switch

产品用途及使用范围 Application and Service Range of Product


本系列分接开关适用于频率50Hz,额定电压等级为10KV~20KV,额定通过电流10A~63A的油浸式电力变压器中。当需要调整电压时,必须将变压器从网络上切除。使变压器在无励磁的情况下改变变压器初级线圈匝数,以实现变压器电压调整的目的。达到调整次级输出电压的目的。

This series of tapping switches are suitable for the oil immersed transformer with frequency 50HZ, rated voltage 10KV20KV,rated current 10A63A,When needing to regulate voltage, must have the transformer cut off from coil of transformer, be changed under no-load condition so as to realize the purpose to regulate the voltage of the transformer; and reach the purpose to regulate the secondary-grade output voltage.
