Yam twg ntawm reactive fall fais fab kev daws teeb meem yuav tsum tau xaiv rau qhov nruab nrab ntawm lub cub hluav taws xob?
Vim tias lub zog muaj teeb meem ntawm lub zog nruab nrab lub zog, uas yog feem ntau yog ua kom muaj zog xws li muaj kev sib haum xeeb, thiab peb theem tsis txaus. Lub ntsiab lus tseem ceeb ntawm cov zaus hluav taws xob taws sib xyaw ua hluav taws xob lub zog nyiaj tau yog los them rau cov kev thauj khoom thiab kho kom haum xeeb.

① Raws li cov kev ua haujlwm ntawm cov khoom siv hluav taws xob, thaum txhim kho cov hluav taws xob fais fab hluav taws xob hauv cov hluav taws xob sib zog hauv cov hluav taws xob hauv qab; Ntxiv mus, ib txoj kev sib xyaw ntawm cov khoom siv hluav taws xob ib leeg thiab cov teeb meem hluav taws xob feem ntau yuav tsum tau txais los daws cov teeb meem peb-theem tsis txaus ntawm cov nruab nrab ntawm cov cub hluav taws xob nruab nrab.

② Thaum txhim kho cov kev them nyiaj fais fab fais fab nyiaj pab rau cov nruab nrab zaus ua kom muaj zog, nws yog qhov zoo tshaj plaws kom muaj peev xwm siv tau. Piv txwv li, tshwj xeeb capacitors rau hluav taws xob arc rauv.

③ Txij li thaum lub zog hluav taws xob ntawm lub zog nruab nrab muaj zog muaj 5, 7 thiab 9th Harmonsents, cov Harmonic Cheebtsam yog qhov nyuaj heev hauv xwm; Yog li ntawd, lub tuam txhab yuav tsum tau thov cov ntxaij lim dej ua haujlwm kom ua rau muaj kev sib raug zoo los tiv thaiv kev sib raug zoo los ntawm kev ua kom raug mob rau lub hwj chim sib tw.

Cov Hom Phiaj Tsim Cov Khoom Siv Hluav Taws Xob Lim Hluav Taws Xob (APF):
Ation kev ua haujlwm ib txwm raws li cov hluav taws xob siab distortion tus nqi;
▶ Tshaj tawm ntawm hmoov av tiv thaiv thiab cua sov dissipation;
Cov muaj zog tiv taus cuam tshuam rau kev cuam tshuam thiab kev cuam tshuam, muaj peev xwm ntawm cov zis puv ntoob; Cov kev daws hauv qab no yog saws los:
▶ Rau LCL, lub peev xwm loj damping distors thiab capined nrog kev ua haujlwm nquag, uas tuaj yeem ua haujlwm tsis txaus ntseeg nyob rau hauv lub zog hluav taws xob nruj;
▶ Cov khoom siv muaj cov npoo loj, nrog lub ncov coefficient ntawm 4 zaug, ua haujlwm puv ntoob;
▶ centrifugal loj-muaj peev xwm ntxuam rau cua sov dissipation, tsuas yog rau cov cua sov thiab indulation tsis nyob hauv huab cua, cov rwb thaiv tsev zoo rau tshav kub dissipation;
▶ ntsug qauv tsim, cov pa hluav taws xob hauv qab, sab saum toj cua qhib rau cov plua plav, muaj cov khoom pov thawj plua plav, cov khoom pov thawj hmoov av zoo;
▶ nyob rau hauv cov xwm txheej ntawm kev ua kom muaj kev tawm tsam, tsim qauv loj dua, uas tuaj yeem ua haujlwm nyob rau hauv cov kev hloov pauv sai lossis cuam tshuam;
▶ Tsoos Synneder cov neeg tuaj cuag tuaj, piv nrog onboard relays, yog tiv taus ntau dua rau kev cuam tshuam thiab tuaj yeem tiv taus loj dua cov dej ntws.
▶ Kev Ua Haujlwm Ua Haujlwm Kev Ua Haujlwm Ntawm 208V rau 750V, kev tsim qauv tsim yog hloov tau thiab muaj ntau haiv neeg;
▶ Txhua yam siv rau loads tsis-linear, cov tshuab hluav taws xob loj, tshuab hluav taws xob, tshuab hotshia, mine foists, hluav taws xob locomotive fais fab mov tshuab.
