Cov kev sib raug zoo ntawm capacitors thiab lub hwj chim tseem ceeb: tus yuam sij rau txhim kho hluav taws xob efficiency

Tsis ntev los no, Navitas qhia tau cov CRPS 185 4.5KW EI cov ntaub ntawv centre mov, uas sivYmin's CW3 1200uf, 450VMuaj peev xwm. Cov tshuaj uas capacitor tso cai rau lub zog siv hluav taws xob kom ua tiav 97% lub zog ua haujlwm ntawm ib nrab-thauj. Qhov kev nce qib thev naus laus zis no tsis yog tsuas yog ua kom zoo rau lub zog ua haujlwm tab sis kuj txhim kho txhim kho lub zog txuag hluav taws xob, tshwj xeeb ntawm cov khoom ntim qis. Txoj kev txhim kho no yog qhov tseem ceeb rau cov ntaub ntawv lub zog tswj thiab txuag hluav taws xob tsis muaj kev siv hluav taws xob tab sis kuj txo cov nqi ua haujlwm.

Hauv cov tshuab hluav taws xob niaj hnub, capacitors siv tsis yog rauLub Zog CiaThiab lim tab sis kuj ua tau lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog muaj zog. Lub zog hluav taws xob yog qhov taw qhia hluav taws xob, thiab capacitors, muaj kev cuam tshuam zoo rau kev txhim kho cov kev ua tau zoo tag nrho ntawm cov tshuab hluav taws xob. Kab lus no yuav tshawb txog lub peev xwm kev muaj peev xwm cuam tshuam rau lub zog rau lub zog thiab tham txog lawv lub luag haujlwm hauv kev siv.

1. Cov ntsiab cai tseem ceeb ntawm capacitors

Lub capacitor yog cov hluav taws xob sib xyaw ua ke ntawm ob tus cwj pwm (electrodes) thiab cov khoom siv insulating (dienectric). Nws lub luag haujlwm tseem ceeb yog khaws thiab tso tawm hluav taws xob hluav taws xob hauv kev hloov pauv tam sim no (AC) Circuit. Thaum AC tam sim no ntws los ntawm lub capacitor, ib daim teb hluav taws xob yog tsim nyob rau hauv cov capacitor, khaws lub zog. Raws li cov kev hloov pauv tam sim no, tusmosTso tawm lub zog no. Qhov peev xwm no khaws cia thiab tso lub zog ua kom muaj peev xwm kho tau theem kev sib raug zoo ntawm qhov tam sim no thiab hluav taws xob, uas yog qhov tshwj xeeb tshaj plaws hauv kev taw qhia.

Cov xeeb ceem no ntawm capacitors pom tseeb hauv kev siv cov ntawv thov. Piv txwv li, hauv lim voj voog, capacitors tuaj yeem thaiv ncaj qha tam sim no (DC) thaum tso cai AC cim tseg, yog li txo suab nrov hauv lub teeb liab. Hauv lub zog hluav taws xob, capacitors tuaj yeem sib npaug sib xyaw hauv Circuit Coupurations nyob rau hauv Circuit Coupurations nyob rau hauv Circuit Coupurations nyob rau hauv Circuit Coupurations nyob rau hauv Circuit Coupurations thiab kev ntseeg tau ntawm lub zog system.

2. Lub tswv yim ntawm lub hwj chim

Hauv AC Circuit Court, lub zog muaj zog yog qhov sib piv ntawm lub zog tiag tiag (lub zog tiag tiag) rau lub zog pom meej. Lub zog hloov pauv tiag tiag yog lub zog hloov pauv hauv Circuit Court, thaum pom meej lub zog hauv Circuit Court, suav nrog ob qho tib si lub zog thiab muaj zog. Lub zog muaj hwj chim (PF) yog muab los ntawm:

Qhov twg P yog lub zog tiag tiag thiab s yog lub zog pom zoo. Lub hwj chim muaj txiaj ntsig los ntawm 0 txog 1, nrog qhov tseem ceeb los ze zog rau 1 qhia tau ntau dua kev ua haujlwm hauv kev siv fais fab. Lub zog loj heev txhais tau tias feem ntau ntawm lub zog hloov dua siab tshiab uas qhia tau tias muaj lub zog tsis tshua muaj zog uas muaj zog siv hluav taws xob.

3. Resive Fais Fab thiab Lub Zog Muaj Zog

Hauv AC circuits, lub zog reactive yog hais txog lub zog tshwm sim los ntawm theem sib txawv ntawm qhov tam sim no thiab hluav taws xob. Lub hwj chim no tsis hloov mus ua haujlwm tiag tiag tab sis muaj vim muaj lub zog cia ntawm inductors thiab capacitors. Inductors feem ntau qhia cov txheej txheem zoo, thaum capacitors qhia cov khoom siv tsis zoo. Lub xub ntiag ntawm cov hluav taws xob cuam tshuam hauv kev txo qis hauv lub zog, raws li nws nce cov chav ua haujlwm tag nrho yam tsis muaj peev xwm ua haujlwm muaj txiaj ntsig.

Ib qho kev txo qis hauv lub hwj chim feem ntau qhia txog qib siab dua ntawm cov hluav taws xob siab dua hauv Circuit Court hauv lub Circuit Court, ua rau kev txo qis ntawm lub zog hluav taws xob. Ib txoj hauv kev zoo los txo lub zog ua haujlwm yog los ntawm kev ntxiv capacitors, uas tuaj yeem pab txhim kho lub zog hluav taws xob thiab, nyob rau hauv lem, txhim kho qhov ua tiav ntawm lub zog hluav taws xob.

4. Kev cuam tshuam ntawm capacitors ntawm lub hwj chim

Capacitors muaj peev xwm txhim kho lub zog muaj zog los ntawm kev txo cov hwj chim. Thaum muaj peev xwm capacitors tau siv hauv Circuit Court, lawv tuaj yeem ua rau qee qhov kev siv hluav taws xob tawm tsam los ntawm Inductors, yog li txo lub zog reactive hauv Circuit Court hauv Circuit Court. Cov nyhuv no tuaj yeem ua kom nce lub hwj chim loj, coj nws los ze zog rau 1, uas txhais tau tias kev siv hluav taws xob tau zoo heev.

Piv txwv li, hauv cov tshuab hluav taws xob muaj zog, capacitors tuaj yeem siv los them nyiaj rau cov hluav taws xob reactive qhia los ntawm inductive thauj los ntawm cov hwj txwv thiab hloov pauv. Los ntawm kev ntxiv kev tsim nyog capacitors rau lub kaw lus, lub hwj chim siv tau txhim kho, txo lub zog ua kom muaj zog thiab ua kom muaj kev ua tau zoo ntawm kev siv hluav taws xob.

5. Capacitor kev teeb tsa hauv kev siv

Hauv kev siv cov kev siv, kev teeb tsa ntawm capacitors feem ntau cuam tshuam nrog qhov xwm ntawm lub nra. Rau kev thauj khoom (xws li xws li motors thiab transformers), Capacers tuaj yeem siv los them rau cov hluav taws xob ua kom muaj zog, yog txhim kho lub zog muaj txiaj ntsig. Piv txwv li, hauv cov tshuab hluav taws xob, siv cov txhab nyiaj hluav taws xob tuaj yeem txo cov hwj huam sib hloov thiab cov cable, txhim kho kev sib hloov pauv kev ua tau zoo thiab txo hwj huam poob.

Nyob rau hauv ib puag ncig lub siab xws li cov ntaub ntawv cov chaw, capacitor configuration yog qhov tshwj xeeb tshaj yog. Lub Navitas Crps 185 4.5KW Ai Cov Ntaub Ntawv Chaw Fais Fab Khoom Siv, Piv txwv li, siv Ymin'sCw31200uf, 450VCapacitors kom ua tiav 97% lub zog ua haujlwm ntawm ib nrab-thauj. Qhov kev teeb tsa no tsis yog ua rau muaj kev ua tau zoo ntawm lub zog ntawm lub zog xwb tab sis kuj ua tau zoo tshaj plaws kev tswj hwm ntawm lub chaw khaws ntaub ntawv. Xws li kev txhim kho thev naus laus zis pab cov ntaub ntawv cov chaw teeb tsa cov nqi hluav taws xob tsawg dua txo qis kev ua haujlwm.

6. Ib nrab-load zog thiab capacitors

Ib nrab-load fais fab hais txog 50% ntawm lub ntsuas cua nab. Hauv kev siv cov tswv yim, cov peev xwm tsim nyog tuaj yeem ua kom zoo rau lub zog ntawm lub nra, Li txhim kho lub zog siv hluav taws xob ua haujlwm ntawm ib nrab-nra. Piv txwv li, lub cev muaj zog nrog lub zog muaj zog ntawm 1000W, yog tias nruab nrog capacitors uas tsim nyog, tuaj yeem tswj hwm lub zog ntawm 500W, ua kom muaj zog siv zog. Qhov no yog qhov tshwj xeeb tshaj yog rau kev siv nrog cov khoom siv thauj khoom, vim nws muaj kev ruaj ntseg ntawm qhov system txoj haujlwm.

Tag

Daim ntawv thov ntawm capacitors hauv hluav taws xob tsis yog tsuas yog siv hluav taws xob cia thiab lim tab sis rau kev txhim kho cov peev txheej muaj zog thiab ua kom muaj zog tag nrho ntawm lub zog hluav taws xob. Los ntawm kev teeb tsa kom zoo capacitorors capanitorors capanitors, cov fais fab tau txo qis, muaj peev xwm ua tau zoo, thiab ua tau zoo thiab raug nqi zog ntawm lub zog hluav taws xob tuaj yeem txhim kho. To taub lub luag haujlwm ntawm capacitors thiab teeb tsa lawv raws li cov kev thauj khoom tiag tiag yog qhov tseem ceeb los txhim kho kev ua haujlwm ntawm cov hluav taws xob. Kev ua tiav ntawm Navitas Crps 185 4.5kW Ai cov ntaub ntawv hluav taws xob muab piv txwv li cov kev thov siab, muab cov tswv yim muaj txiaj ntsig zoo rau cov tshuab hluav taws xob kom zoo.
