Kev tsom xam ntawm cov laj thawj tshwj xeeb rau cov khoom siv hluav taws xob tsawg ntawm transformer pfc
Kuv, tus cawv ntawm transformer tus kheej cov yam ntxwv
1. Sib nqus flux poob thiab tooj liab
Thaum lub sijhawm ua haujlwm ntawm kev hloov pauv, cov khoom poob edd tam sim no (cov khoom poob los ntawm kev hloov pauv ntawm cov hlau tsis sib xws thiab tso zis ntau zog thiab cuam tshuam lub hwj chim.
2. Npliag lossis lub teeb ua haujlwm
Thaum lub transformer tsis yog tag nrho ntawm nws cov kev ua kom zoo nkauj (reactive zog) rau tag nrho tam sim no nce ntxiv, thiab lub zog hluav taws xob yuav poob hauv qab 0. 2.
3. Tsim muaj peev xwm ua tsis tau
Yog tias lub peev xwm ntawm tus transformer yog ntau dua li cov khoom siv thauj khoom tiag tiag, kev ua kom ntev ntev yuav ua rau muaj kev txuag nyiaj ntev hauv kev siv hluav taws xob thiab kev txo qis hauv lub cev muaj zog.
II, ntsaws cov yam ntxwv thiab kev khiav haujlwm ib puag ncig
1. Qhov kev faib ua feem ntawm inductive load yog siab dhau
Transformers feem ntau muab cov hluav taws xob rau inductive thauj khoom xws li motors thiab reactors, uas yuav tsum muaj ntau yam sib txawv ntawm voltage thiab tam sim no.
2. Cov lus tawm voltage hloov pauv
Thaum cov tswv yim voltage nce, qhov kev zoo siab tam sim no ntawm tus transformer txo yuav ua rau muaj kev cuam tshuam nrog PFC, ua rau muaj kev cuam tshuam rau lub sijhawm tam sim no, ua rau muaj kev cuam tshuam nrog lub sijhawm tam sim no los ntawm Inductor tam sim no tau ntev thiab th thiv kom nce ntxiv.
III. Harmov ua phem
Cov kev sib haum xeeb tsim los ntawm cov khoom siv tsis sib xws (xws li cov hluav taws xob hloov kho dua tshiab ntawm kev kho hluav taws xob ntawm kev hloov pauv ntawm PFC lossis ua rau muaj peev xwm ua rau muaj kev sib hloov.
3, kaw cov teeb meem thiab tswj cov teeb meem
1. Kev them nyiaj tsis txaus ntseeg
Yog tias muaj cov txhab nyiaj sib txuas los yog cov khoom siv them nyiaj siv (xws li SVG) tsis yooj yim sua kom tshem tawm cov khoom siv hluav taws xob uas tsim los ntawm kev hloov pauv thiab thauj khoom.
2. Txiaj Ntsig Ncauj Lus ntawm PFC tsis
Thaum PFC tus tswj hwm (xws li inductance thiab hloov cov peev xwm rov qab los yog kev tshem tawm cov peev xwm lossis tshem tawm yuav tshwm sim hauv lub hwj chim.
3. Qhov kub cuam tshuam rau ntaus ntawv ua haujlwm
Nyob rau hauv qhov chaw kub ib puag ncig, lub peev xwm ntawm lim caccitors txo qis lossis qhov sib npaug ntawm PFC cov hluav taws xob ntawm cov nthwv dej tam sim no thiab tsis ncaj txo lub zog.
IIII, ntsuas kev txhim kho kom raug
1. Dynamic Them Kev Kho Kom Zoo Dua: Siv Hybrid Resive Fais Fab Kev Them Nyiaj (xws li SVG + Capacitor bank) kom phim cov fais fab sib txawv ntawm lub sijhawm tiag tiag;
2. Load Kev Tswj Xyuas: kom tsis txhob muaj lub teeb lub teeb ntev ntawm kev hloov pauv, ua kom zoo txav chaw faib tawm los ntawm kev hloov pauv mus ua ke;
3. Harmonic Kev Tswj: Txhim Kho LC lim dej lossis lub zog hluav taws xob lim dej (APF) kom txo qis qhov kev cuam tshuam ntawm kev cuam tshuam ntawm PFC voj voog;
4. Parameter Tuning: Kho PFC Inductance thiab hloov cov zaus raws cov kev ua haujlwm hloov pauv (CCM) npog cov tswv yim dav dav.
