Tsis ntev los no, Navitas tau qhia txog CRPS 185 4.5kW AI data center fais fab mov, uas sivYMIN's CW3 1200uF, 450Vcapacitors. Qhov kev xaiv capacitor no tso cai rau cov khoom siv hluav taws xob kom ua tiav 97% lub zog ntawm ib nrab-load. Qhov kev txhim kho thev naus laus zis no tsis yog tsuas yog ua kom lub zog ua haujlwm tau zoo xwb tab sis kuj tseem txhim kho kev siv hluav taws xob zoo, tshwj xeeb ntawm cov khoom qis. Qhov kev txhim kho no tseem ceeb heev rau cov ntaub ntawv chaw tswj fais fab thiab txuag hluav taws xob, vim tias kev ua haujlwm tau zoo tsis yog txo qis kev siv hluav taws xob nkaus xwb tab sis kuj txo cov nqi ua haujlwm.
Hauv cov tshuab hluav taws xob niaj hnub no, cov capacitors tsis yog siv rau xwblub zog ciathiab lim tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog. Lub zog hluav taws xob yog ib qho tseem ceeb qhia txog kev ua haujlwm ntawm hluav taws xob, thiab cov capacitors, raws li cov cuab yeej zoo rau kev txhim kho lub zog, muaj kev cuam tshuam loj rau kev txhim kho tag nrho cov kev ua haujlwm ntawm cov hluav taws xob. Kab lus no yuav tshawb xyuas seb cov capacitors cuam tshuam li cas rau lub zog thiab sib tham txog lawv lub luag haujlwm hauv kev siv tswv yim.
1. Cov Ntsiab Cai ntawm Capacitor
Lub capacitor yog ib qho khoom siv hluav taws xob uas ua los ntawm ob lub conductors (electrodes) thiab cov khoom siv insulating (dielectric). Nws lub luag haujlwm tseem ceeb yog khaws cia thiab tso tawm hluav taws xob hauv hluav taws xob hloov hluav taws xob (AC). Thaum AC tam sim no ntws los ntawm lub capacitor, lub teb hluav taws xob yog tsim nyob rau hauv lub capacitor, khaws cia lub zog. Raws li kev hloov pauv tam sim no, lubcapacitortso tawm lub zog khaws cia no. Qhov kev muaj peev xwm khaws cia thiab tso tawm lub zog ua rau cov capacitors zoo hauv kev kho cov theem kev sib raug zoo ntawm qhov tam sim no thiab qhov hluav taws xob, uas yog qhov tseem ceeb tshwj xeeb hauv kev tuav AC cov cim.
Cov yam ntxwv ntawm capacitors no yog pom tseeb hauv kev siv tswv yim. Piv txwv li, nyob rau hauv lim circuits, capacitors tuaj yeem thaiv qhov tam sim no ncaj qha (DC) thaum tso cai rau AC teeb liab hla, yog li txo cov suab nrov hauv lub teeb liab. Hauv cov tshuab hluav taws xob, cov capacitors tuaj yeem sib npaug qhov hloov pauv ntawm qhov hluav taws xob hauv Circuit Court, txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm lub zog hluav taws xob.
2. Lub tswv yim ntawm lub hwj chim Factor
Hauv AC Circuit Court, lub hwj chim yog qhov piv ntawm lub zog tiag tiag (lub zog tiag tiag) rau lub zog pom tseeb. Lub zog tiag tiag yog lub zog hloov mus rau hauv kev ua haujlwm muaj txiaj ntsig hauv Circuit Court, thaum lub zog pom tseeb yog tag nrho lub zog hauv Circuit Court, suav nrog lub zog tiag tiag thiab lub zog reactive. Lub hwj chim factor (PF) yog muab los ntawm:
qhov twg P yog lub hwj chim tiag tiag thiab S yog lub zog pom. Lub hwj chim qhov sib txawv ntawm 0 mus rau 1, nrog rau qhov tseem ceeb ze rau 1 qhia tias muaj kev ua tau zoo dua hauv kev siv hluav taws xob. Lub hwj chim loj txhais tau hais tias feem ntau ntawm lub hwj chim tau hloov mus rau hauv kev ua haujlwm muaj txiaj ntsig, thaum lub zog qis qhia tau hais tias lub zog tseem ceeb yog nkim li lub zog reactive.
3. Reactive hwj chim thiab lub hwj chim Factor
Hauv AC circuits, reactive fais fab yog hais txog lub zog los ntawm theem sib txawv ntawm qhov tam sim no thiab voltage. Lub hwj chim no tsis hloov mus rau hauv kev ua haujlwm tiag tiag tab sis tshwm sim vim lub zog cia cov teebmeem ntawm inductors thiab capacitor. Inductors feem ntau qhia qhov zoo reactive zog, thaum capacitors qhia tsis zoo reactive zog. Lub xub ntiag ntawm reactive hwj chim ua rau txo efficiency nyob rau hauv lub hwj chim system, raws li nws tsub kom lub zuag qhia tag nrho load yam tsis ua hauj lwm pab.
Kev txo qis hauv lub zog feem ntau qhia txog qib siab dua ntawm lub zog reactive hauv Circuit Court, ua rau txo qis ntawm tag nrho cov txiaj ntsig ntawm lub zog hluav taws xob. Ib txoj hauv kev zoo los txo lub zog reactive yog los ntawm kev ntxiv cov capacitors, uas tuaj yeem pab txhim kho lub zog ntawm lub zog thiab, dhau los, txhim kho tag nrho cov txiaj ntsig ntawm lub zog.
4. Kev cuam tshuam ntawm Capacitor ntawm Lub Hwj Chim Fais Fab
Capacitors tuaj yeem txhim kho lub zog ua haujlwm los ntawm kev txo lub zog reactive. Thaum siv cov capacitors hauv Circuit Court, lawv tuaj yeem cuam tshuam qee lub zog reactive qhia los ntawm inductors, yog li txo tag nrho cov reactive zog hauv Circuit Court. Cov nyhuv no tuaj yeem ua rau muaj zog ntau ntxiv, coj nws los ze zog rau 1, uas txhais tau hais tias kev siv hluav taws xob tau zoo dua qub.
Piv txwv li, nyob rau hauv kev lag luam fais fab tshuab, capacitors tuaj yeem siv los them rau lub zog reactive qhia los ntawm inductive loads xws li motors thiab transformers. Los ntawm kev ntxiv cov capacitors tsim nyog rau lub kaw lus, lub zog zoo tuaj yeem txhim kho, txo cov hluav taws xob poob thiab ua kom cov txiaj ntsig ntawm kev siv hluav taws xob.
5. Capacitor Configuration nyob rau hauv daim ntawv thov
Hauv kev siv tswv yim, kev teeb tsa ntawm cov capacitors feem ntau zoo sib xws rau qhov xwm txheej ntawm lub nra. Rau inductive loads (xws li motors thiab transformers), capacitors tuaj yeem siv los them rau lub zog reactive qhia, yog li kev txhim kho lub zog. Piv txwv li, hauv kev lag luam hluav taws xob, siv cov tsev txhab nyiaj capacitor tuaj yeem txo cov hluav taws xob reactive lub nra ntawm transformers thiab cables, txhim kho lub zog xa hluav taws xob thiab txo cov hluav taws xob poob.
Nyob rau hauv ib puag ncig high-load xws li cov chaw zov me nyuam, kev teeb tsa capacitor yog qhov tseem ceeb tshwj xeeb. Navitas CRPS 185 4.5kW AI data center fais fab mov, piv txwv li, siv YMIN'sCW 31200uF, 450Vcapacitors kom ua tiav 97% lub zog ntawm ib nrab-load. Qhov kev teeb tsa no tsis tsuas yog txhim kho qhov ua tau zoo ntawm cov khoom siv hluav taws xob tab sis kuj ua kom zoo rau kev tswj hwm lub zog tag nrho ntawm cov ntaub ntawv chaw. Cov kev txhim kho thev naus laus zis no pab cov chaw zov me nyuam cov ntaub ntawv txo cov nqi hluav taws xob thiab txhim kho kev ua haujlwm ruaj khov.
6. Ib nrab-Load Fais Fab thiab Capacitor
Ib nrab-load hwj chim hais txog 50% ntawm lub zog ntsuas. Hauv kev siv cov tswv yim, kev teeb tsa capacitor kom zoo tuaj yeem txhim kho lub zog ntawm cov khoom thauj, yog li txhim kho kev siv hluav taws xob zoo ntawm ib nrab-load. Piv txwv li, lub cev muaj zog nrog lub zog ntsuas ntawm 1000W, yog tias nruab nrog cov khoom siv hluav taws xob tsim nyog, tuaj yeem tswj hwm lub zog hluav taws xob ntau txawm tias muaj qhov hnyav ntawm 500W, kom ntseeg tau tias siv lub zog zoo. Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb rau daim ntawv thov nrog fluctuating loads, raws li nws txhim khu kev ruaj ntseg ntawm lub system ua hauj lwm.
