- Khoom Taw qhia
AC Input Reactor rau VFD (tseem hu ua AC line reactor lossis input choke) yog ib qho khoom siv hluav taws xob siv hauv hluav taws xob hluav taws xob kom du tam sim no, txo cov kev sib haum xeeb, thiab tiv thaiv cov khoom siv hluav taws xob. Nws muaj ib tug coiled conductor (feem ntau ntawv ci winding rau kev ua tau zoo dua) qhov txhab nyob ib ncig ntawm ib tug sib nqus core, tsim los lis alternating tam sim no (AC) inputs.
Cov yam ntxwv tseem ceeb thiab kev ua haujlwm
1. Kev Tiv Thaiv Kev Nyuaj Siab
txwv siab -frequency harmonics generated los ntawm non-linear loads (variable zaus drives, rectifiers)
Pab ua raws li cov qauv xws li IEEE 519 lossis IEC 61000-3
2. Tam sim no Smoothing
Txo tam sim no distortion thiab txhim kho lub zog zoo.
Tiv thaiv tam sim ntawd inrush tam sim no.
3. Voltage Spike Protection
Ua raws li qhov tsis tuaj yeem tiv thaiv qhov hluav taws xob hloov pauv hloov pauv los ntawm kab sib chaws lossis hloov cov xwm txheej.
4. dv/dt Kev txwv
Kev hloov pauv sai sai (dv / dt), tiv thaiv capacitors thiab semiconductors.
5. Kev txhim kho fais fab
Nws tuaj yeem txhim kho kev hloov pauv hluav taws xob me ntsis saum toj no mus rau 0.95 los ntawm kev txo cov theem distortion.
Cov yam ntxwv hluav taws xob
Inductance thiab impedance
Hom Inductance Range: 50 μH txog 10 mH (nws txawv ntawm daim ntawv thov).
% impedance (Z%):
1-3%: me me harmonic filtering, inrush limiting.
5-10%: Kev sib haum xeeb muaj zog, kev tiv thaiv lub cev muaj zog.
Formula:
Zaus teb
Tsim los rau 50/60 Hz, tab sis yuav tsum ua kom muaj kev sib haum xeeb (txog 2-3 kHz).
Tus kheej -Resonant Frequency (SRF):
Yuav tsum tau siab tshaj qhov siab tshaj plaws harmonic zaus kom tsis txhob plam resonance.

Qauv thiab Tsim
● Foil Winding: Hloov cov hlau ib txwm siv, cov ntaub ntawv tiaj tus (feem ntau yog txhuas lossis tooj liab) yog siv rau kev ua haujlwm qis dua, kev ua kom sov zoo dua, thiab kev tuav ntau dua tam sim no.
● Laminated Core: Feem ntau yog ua los ntawm silicon steel lossis lwm yam khoom siv hlau nplaum kom txo qis qhov poob tam sim no.
● Rwb thaiv tsev: High- qib rwb thaiv tsev ntawm cov ntawv ci txheej kom tiv taus qhov kub thiab txias.
