1、产品选用须知(Product selection notice)
1、HFL特别适用于VFD或其它6 脉冲整流器电源的输入端,几乎消除了谐波畸变;
2、HFL实现更优秀的THDI性能,提高电能效率,会让您的系统完全满足谐波标准(IEEE-519、EN61000-3-2等)要求
3、HFL的所有电气安装和维护工作应该由具备资格的电气工程师操作,HFL和连接装置必须接地;
4、HFL切断电源后,需要等中间回路电容自行放电3分钟,对前后级操作前,请使用万用表确认HFL进出端子是否已经放电完毕;
5、HFL与负载功率匹配使用时可以获得好的滤波效果,功率较大的HFL可以用于功率较小的负载,但滤波效果会降低;
6、HFL可为多台VFD供电,但总负荷不得超过 HFL 的额定功率值。

备注(remark): 在电源电压的THVD低于2%(线电压平衡度小于1%)且短路功率与已安装负载比(RSCE)>66时,将VFD满载时的电源电流THDI降低到HFL额定负载下的典型数值以下,在不符合这些条件或仅部分符合这些条件的情况下,虽然仍可使谐波明显减少,但不会达到THDI 的额定值。 When the THVD of the supply voltage is less than 2%(line voltage balance is less than 1%) and the short-circuit power to installed load ratio (RSCE) is >66, the THDI of the supply current at full VFD is reduced to HFL Below the typical value at the rated load, in the case that these conditions are not met or only partially met, although the harmonics can still be significantly reduced, it will not reach the rating of THDI. | |||
