Lub inverter yog fais fab kev hloov kho cov cuab yeej sib haum ntawm cov khoom siv semiconductor, uas yog siv los hloov DC lub zog rau hauv AC Fais Fab. Nws yog feem ntau tsim ntawm kev txhawb nqa Circuit Court thiab inverter Choj Circuit Court. Lub Boost Circuit CoTs lub DC voltage ntawm lub hnub ci rau lub dc voltage yuav tsum muaj rau cov inverter tso zis kev tswj hwm; Cov Inverter Choj Hloov Hloov Cov Hloov Potrts The Boosted DC voltage mus rau hauv ib qho poltage nrog ib zaus sib npaug.
Inverter, tseem hu ua lub zog tswj hwm, tuaj yeem faib ua kev ywj pheej thiab sib txuas nrog siv cov inverter hauv lub photovoltaic lub zog hluav taws xob. Raws li kev ua kom cov txheej txheem Waveform Rau inverters siv hauv cov kab ke sib txuas, lawv tuaj yeem faib ua cov tshuab inverters thiab transformer-tsawg interverers raws li txawm muaj transformer. Lub ntsiab kev tsis ntsuas ntawm Hnub ci photoovoltaic inverter yog:
1. Kev Tso Tawm Voltage Volfage
Lub photovoltaic inverter yuav tsum muaj peev xwm tawm cov ntsuas hluav taws xob muaj nuj nqis hauv cov lus pom zoo ntawm cov tswv yim sau tseg DC voltage. Feem ntau, thaum cov ntsuas hluav taws xob voltage yog ib leeg-theem 220V thiab peb-theem 380v, cov voltage flucess yog teev raws li hauv qab no.
(1) Thaum khiav hauv lub xeev khov kho, feem ntau nws yuav tsum tau ua yog qhov sib zog hluav taws xob tsis dhau ± 5% ntawm tus nqi ntsuas.
(2) Thaum lub nra tau hloov pauv, lub voltage sib txawv tsis pub tshaj ± 10% ntawm tus nqi ntsuas.
(3) Raws li kev ua haujlwm ua haujlwm qub, qhov tsis muaj kev tsis sib xws ntawm peb-theem voltage tso zis los ntawm cov inverter yuav tsum tsis pub tshaj 8%.
(4) Qhov txawv txav ntawm lub voltage waveform (sine yoj) ntawm peb-theem tso zis yog feem ntau yuav tsum tsis pub tshaj 5%, thiab ib leeg-theem tsim tawm yuav tsum tsis pub tshaj 10%.
(5) Qhov sib txawv ntawm cov zaus ntawm cov zis inverter acverter actures potorage yuav tsum tsis pub dhau 1% raws li kev ua haujlwm li qub. Cov zis hluav taws xob ntau teev nyob rau hauv lub teb chaws tus qauv GB / T 19064-2003 yuav tsum nyob nruab nrab ntawm 49 thiab 51Hz.
2. Thauj cov khoom siv hluav taws xob
Qhov loj ntawm lub nra cov khoom siv hluav taws xob qhia tau tias muaj peev xwm ntawm Inverter nqa cov khoom lag luam inductive lossis caperitive thauj. Nyob rau hauv cov xwm txheej ntawm sine yoj, lub nra hnyav factor yog 0.7 mus rau 0.9, thiab tus nqi rated yog 0.9. Nyob rau hauv cov ntaub ntawv ntawm qee lub zog load, yog tias lub zog muaj zog ntawm inverter yog tsawg, qhov xav tau ntawm lub inverter yuav nce ntxiv, ua rau muaj kev nce ntxiv. Nyob rau tib lub sijhawm, lub zog pom tseeb ntawm AC Circuit Court ntawm lub photovoltaic nce, thiab lub Circuit Court tam sim no nce ntxiv. Yog tias nws loj, qhov poob yuav zam kev nce ntxiv, thiab qhov system efficiency yuav tseem poob.
3. Rated Tso Tawm Tam Sim No Thiab Cov Khoom Siv Hluav Taws Xob
Cov tso zis tso tawm tam sim no yog hais txog qhov tso zis tso tawm tam sim no ntawm Inverter hauv lub zog thauj khoom ntau, chav ntsuas yog ib qho; Kev ntsuas ntsuas cov zis muaj peev xwm hais txog cov khoom ntawm cov khoom siv hluav taws xob voltage thiab tso zis tawm cov khoom siv hluav taws xob tam sim no yog 1 (ie Cov Khoom Siv ntshiab muaj zog), chav ntsuas yog KVA lossis KW.
