1. 產品選用須知
1. HFL特別適用于VFD或其它6 脈沖整流器電源的輸入端，幾乎消除了諧波畸變；
HFL is especially suitable for the input of VFD or other 6-pulse rectifier power supplies, almost eliminating harmonic distortion
2. HFL實現更優秀的THDI性能，提高電能效率，會讓您的系統完全滿足諧波標準（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的所有電氣安裝和維護工作應該由具備資格的電氣工程師操作，HFL和連接裝置必須接地；
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切斷電源后，需要等中間回路電容自行放電3分鐘，對前后級操作前，請使用萬用表確認HFL進出端子是否已經放電完畢；
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與負載功率匹配使用時可以獲得最佳的濾波效果，功率較大的HFL可以用于功率較小的負載，但濾波效果會降低；
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可為多臺VFD供電，但總負荷不得超過 HFL 的額定功率值。
The HFL can supply power to multiple VFDS, but the total load must not exceed the rated power value of the HFL

備注（remark）： 在電源電壓的THVD低于2%(線電壓平衡度小于1%)且短路功率與已安裝負載比（RSCE）>66時，將VFD滿載時的電源電流THDI降低到HFL額定負載下的典型數值以下，在不符合這些條件或僅部分符合這些條件的情況下，雖然仍可使諧波明顯減少，但不會達到THDI 的額定值。 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選擇指導：(HFL Selection Guide)
1） HFL額定電流（HFLRated current）：
為了發揮HFL的最優濾波性能，在選擇合適的HFL時，請根據變頻器所帶負載功率來選，以確定HFL的額定電流。
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
計算式（Calculation formula）：Irms=Pload/(Urms* EM * EVFD * EHFL *√3)
例（example）：
電網電壓(Urms): 380V
電網頻率（F）: 50Hz
電機功率(Pload): 160kW
電機效率(EM): 92%
變頻器效率(EVFD): 95%
HFL最低效率（EHFL）: 96%
根據上述計算式得：290A，選擇大于或等于290A諧波濾波器（HFL05-0304A4005，額定電流304A）,實測結果如下：
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） 電容投切用接觸器(Capacitive switching contactor)：
HFL濾波器在無負載的情況下，功率因數為0，電容器將產生約30%的超前無功電流。在無功電流不可接受的應用情況下，可將交付默認短接端子X1/Y1/Z1與X2/Y2/Z2斷開。另外，直接由發電機供電的系統，在設計中考慮無功電流非常重要，因為在無負載或低負載運行時，無功電流可使發電機過勵磁以致發電機輸出電壓升高，超過HFL和變頻器的允許電壓值。因此，在發電機直供電源電路中務必使用電容斷路接觸器。
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.
建議：10%-20%負載時投切電容模組，重新投入電容時須間隔最少30S。
Suggestion: Switch the capacitor module when the load is 10%-20%, and reinsert the capacitor at least 30 seconds.
接觸器額定電流選擇：HFL額定電流50%以上（AC3型）
Selection of rated current of contactor：HFL rated current above 50% (AC3 type)
例：HFL05-0304A4005選擇接觸器的額定電流最小值為304*0.5=152A
HFL05-0304A4005 Select a minimum rated current of the contactor of 152A
注意：使用接觸器投&切電容模組時，絕不能在全負載時連接電容，或在無負載時斷開電容。
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） 電流保險絲（Current fuse）：
電流保險絲額定電流選擇范圍：1.8~2.5倍HFL額定電流
Current Rated current range of the fuse：1.8~2.5 times HFL rated current
例：HFL05-0304A4H5選擇電流保險絲額定電流范圍為304*1.8~2.5=547~760A
Fxample ：HFL05-0304A4H5 Select current The rated current of the fuse ranges from 547 to 760A
