Peb theem Hnub Ci Inverter Taw Qhia

Peb theem hnub ci inverter yog dab tsi?

CovPeb theem hnub ci inverteryog ib hom inverter siv nyob rau hauv lub hnub ci zog tshuab los hloov DC (direct tam sim no) hluav taws xob tsim los ntawm lub hnub ci vaj huam sib luag rau hauv AC (alternating tam sim no) hluav taws xob haum rau siv nyob rau hauv tsev los yog cov lag luam.

Lub sij hawm“three-phase”hais txog hom hluav taws xob uas lub inverter ua haujlwm.Nyob rau hauv peb-theem system, muaj peb txoj kab sib cais los yog theem sib cais los ntawm ib leeg los ntawm 120 degrees, ua rau muaj kev sib npaug thiab muaj txiaj ntsig ntawm kev faib hluav taws xob.

Cov noinverterfeem ntau yog siv rau hauv kev lag luam lossis kev lag luam hnub ci kev teeb tsa uas muaj hluav taws xob ntau dua thiab siv tau.Lawv tau tsim los tswj cov hluav taws xob ntau dua thiab lub zog muaj peev xwm tshaj li ib-theem inverters, ua rau lawv haum rau cov hnub ci loj dua.

Yuav ua li casPeb theem hnub ci inverterua haujlwm

Ntawm no yog ib qho yooj yim piav qhia txog peb-theem hnub ci li casinverterhauj lwm:

DC rau AC hloov dua siab tshiab: Lub hnub ci vaj huam sib luag tsim hluav taws xob DC thaum raug tshav ntuj.Lub zog DC no yog pub rau hauvPeb theem hnub ci inverter.

MPPT mus txog qhovtwg: Lub inverter ua qhov Maximum Power Point Tracking (MPPT), uas optimizes lub zog tso zis ntawm lub hnub ci vaj huam sib luag los ntawm kev txiav txim siab qhov voltage thiab tam sim no sib xyaw ua ke uas ua rau lub zog siab tshaj plaws.

Inverter: Lub zog DC hloov mus rau AC lub zog los ntawm cov khoom siv hluav taws xob xws li IGBTs (Insulated Gate Bipolar Transistors) lossis MOSFETs (Hlau-Oxide-Semiconductor Field-Effect Transistors).

Grid synchronization: Covinvertertas li saib xyuas cov kab hluav taws xob thiab qhov zaus kom ntseeg tau tias synchronization nrog daim phiaj siv hluav taws xob.

Tswj lub zog: Lubinverterkho cov zis hluav taws xob raws li qhov xav tau ntawm cov khoom siv hluav taws xob thiab muaj hnub ci zog.

Daim phiaj sib txuas thiab saib xyuas: LubPeb theem hnub ci inverteryog txuas nrog rau daim phiaj siv hluav taws xob, tso cai rau ntau lub zog xa tawm mus rau daim phiaj lossis kos los ntawm kab sib chaws thaum xav tau.

Kev tiv thaiv thiab kev nyab xeeb nta: Peb-theem hnub ciinverteryog nruab nrog ntau yam kev tiv thaiv mechanisms, nrog rau kev tiv thaiv kev tiv thaiv kev tiv thaiv, tiv thaiv overvoltage thiab kev tiv thaiv undervoltage.

Advanced nta ntawmPeb theem hnub ci inverter

1. Ntau MPPT inputs: NtauPeb theem invertermuab ntau yam khoom siv hluav taws xob siab tshaj plaws (MPPT) inputs, tso cai rau kev sib txuas ntawm ntau txoj hlua ntawm lub hnub ci vaj huam sib luag nrog cov kev taw qhia sib txawv lossis cov xwm txheej shading.

2. Reactive hwj chim tswj: Qee yamPeb theem invertermuab siab heev reactive hwj chim tswj.Qhov no feature tso cai rau lub inverter kom nquag tswj cov reactive zog txaus, kom ntseeg tau lub hwj chim zoo kho thiab daim phiaj stability.Nws tso cai rau kev tswj hwm zoo dua thiab ua raws li cov cai ntawm kab sib chaws.

3. Anti-islanding tiv thaiv:Invertersnrog kev tiv thaiv kev tiv thaiv kev tiv thaiv muaj kev ruaj ntseg zoo tshaj plaws uas pom cov kab sib txawv txawv, xws li hluav taws xob hluav taws xob, thiab txiav tawm lub hnub ci ntawm kab sib chaws.Qhov no tiv thaiv cov neeg ua haujlwm siv hluav taws xob los ntawm hluav taws xob muaj teeb meem thaum kho lossis kho.

4. Kev saib xyuas thiab tswj chaw taws teeb: Ntau lub hnub ci peb theeminvertermuaj kev sib txuas lus built-in uas tso cai rau cov chaw taws teeb saib xyuas thiab tswj cov kab ke.

5. Daim phiaj txhawb zog: AdvancedPeb theem invertertuaj yeem muab daim phiaj kev txhawb nqa los ntawm kev tswj qhov voltage thiab zaus.Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv daim phiaj-txuas systems, qhov twg lub inverter yuav nquag stabilize voltage fluctuations thiab pab sib npaug ntawm daim phiaj.

6. Cov txheej txheem kev sib txuas lus zoo tshaj plaws hauv kev sib txuas lus: Ntxiv rau cov chaw taws teeb saib xyuas thiab tswj, qee qhovPeb theem invertertxhawb kev sib txuas lus zoo tshaj plaws xws li Modbus lossis Ethernet, ua kom muaj kev sib koom ua ke nrog lwm cov kev saib xyuas lossis lub zog tswj lub platform.

7. Kev koom ua ke nrog Lub Zog Cia Cov Txheej Txheem: Nrog rau kev loj hlob ntawm cov kev daws teeb meem ntawm lub zog cia, qee qhovPebTheem hnub ci invertermuab kev sib koom ua ke rau cov roj teeb cia tshuab.
