产品详情

  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.

2. 安装场所应无腐蚀气体、蒸气和导电性或爆炸性尘埃,并无剧烈的机械振动。
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,工频过电压下长期运行。
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,最大容差和高至1.2In 的过电流共同作用的结果。
