1. 产品选用须知
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；
HFL is especially suitable for the input of VFD or other 6-pulse rectifier power supplies, almost eliminating harmonic distortion
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
HFL achieves better THDI performance and improves power efficiency, allowing your system to fully meet harmonic standards (IEEE-519, EN61000-3-2, etc；
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；
All electrical installation and maintenance work at the HFL should be performed by a qualified electrical engineer, and the HFL and connection devices must be grounded
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；
After the HFL is powered off, wait for the capacitor in the middle loop to discharge for 3 minutes. Before performing operations on the front and rear stages, use a multimeter to check whether the inlet and outlet terminals of the HFL are discharged
5. HFL与负载功率匹配使用时可以获得最佳的滤波效果，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；
The best filtering effect can be obtained when the HFL is matched with the load power. The HFL with higher power can be used for the load with lower power, but the filtering effect will be reduced.
6. HFL可为多台VFD供电，但总负荷不得超过 HFL 的额定功率值。
The HFL can supply power to multiple VFDS, but the total load must not exceed the rated power value of the HFL

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. | |||

7. HFL选择指导：(HFL Selection Guide)
1） HFL额定电流（HFLRated current）：
为了发挥HFL的最优滤波性能，在选择合适的HFL时，请根据变频器所带负载功率来选，以确定HFL的额定电流。
In order to play the optimal filtering performance of HFL, when selecting the appropriate HFL, please select according to the load power of the inverter to determine the rated current of HFL
计算式（Calculation formula）：Irms=Pload/(Urms* EM * EVFD * EHFL *√3)
例（example）：
电网电压(Urms): 380V
电网频率（F）: 50Hz
电机功率(Pload): 160kW
电机效率(EM): 92%
变频器效率(EVFD): 95%
HFL最低效率（EHFL）: 96%
根据上述计算式得：290A，选择大于或等于290A谐波滤波器（HFL05-0304A4005，额定电流304A）,实测结果如下：
According to the above calculation formula: 290A, select more than or equal to 290A harmonic filter (HFL05-0304A4005, rated current 304A), measured results are as follows:
1） 电容投切用接触器(Capacitive switching contactor)：
HFL滤波器在无负载的情况下，功率因数为0，电容器将产生约30%的超前无功电流。在无功电流不可接受的应用情况下，可将交付默认短接端子X1/Y1/Z1与X2/Y2/Z2断开。另外，直接由发电机供电的系统，在设计中考虑无功电流非常重要，因为在无负载或低负载运行时，无功电流可使发电机过励磁以致发电机输出电压升高，超过HFL和变频器的允许电压值。因此，在发电机直供电源电路中务必使用电容断路接触器。
HFL filters in the case of no load, the power factor is 0, the capacitor will produce about 30% of the lead reactive current. The delivery default shorting terminals X1/Y1/Z1 and X2/Y2/Z2 can be disconnected in an application where the reactive current is unacceptable. In addition, it is important to consider reactive current in the design of systems powered directly by the generator, because during no-load or low-load operation, reactive current can overexcite the generator so that the output voltage of the generator increases beyond the allowable voltage values of the HFL and frequency converter. Therefore, it is necessary to use capacitive break contactors in the generator direct supply source circuit.
建议：10%-20%负载时投切电容模组，重新投入电容时须间隔最少30S。
Suggestion: Switch the capacitor module when the load is 10%-20%, and reinsert the capacitor at least 30 seconds.
接触器额定电流选择：HFL额定电流50%以上（AC3型）
Selection of rated current of contactor：HFL rated current above 50% (AC3 type)
例：HFL05-0304A4005选择接触器的额定电流最小值为304*0.5=152A
HFL05-0304A4005 Select a minimum rated current of the contactor of 152A
注意：使用接触器投&切电容模组时，绝不能在全负载时连接电容，或在无负载时断开电容。
When using a contactor to cast and cut a capacitor module, the capacitor should never be connected at full load or disconnected at no load.
2） 电流保险丝（Current fuse）：
电流保险丝额定电流选择范围：1.8~2.5倍HFL额定电流
Current Rated current range of the fuse：1.8~2.5 times HFL rated current
例：HFL05-0304A4H5选择电流保险丝额定电流范围为304*1.8~2.5=547~760A
Fxample ：HFL05-0304A4H5 Select current The rated current of the fuse ranges from 547 to 760A
