FFM系列防护电容器

用途及适用范围 use and application
　　FFM 型防护电容器可与高压电阻串联构成RC过电压吸收装置，适用与交流35KV 输配电系统中吸收因真空断路器( 或其它不重击穿的开关)开合时产生的过渡过电压，以保护系统内高压电器产品受电压的损害，本产品还可当作高压电容在其他场合下使用。

　　FFMmodel protection capacitorwith high voltage resistancein series being RC is comp osedofvoltage absorption device,itfitswellwith 35kv electric system.due to vacuum breaker(or other non-heavy switch),it produces the transition voltage to protect the product with high voltage from damaging,it is also used on other occasions with high voltage capacitor．

3. 电容器投入运行时，其端子上的剩余电压不超过额定电压的10%。
4. 过载荷
4.1 稳定过电压
续运行电压时1.00μn，并能在1.2μn，工频过电压下*运行。
4.2 操作过电压
电容器的承受不重击穿开关所产生的1.5μn 的过渡过电压( 峰值）。
4.3 稳态过电流
电容器能在1.5In 稳态过电流下运行，这个过电流是由于谐波及，zui大容差和高至1.2In 的过电流共同作用的结果。
