Lub inverter yog ib qho khoom siv hloov hluav taws xob tsim los ntawm cov khoom siv semiconductor, uas yog siv los hloov DC lub zog rau hauv AC lub zog.Nws feem ntau yog tsim los ntawm lub zog hluav taws xob thiab lub inverter choj Circuit Court.Lub boost Circuit Court boosts DC voltage ntawm lub hnub ci cell mus rau DC voltage yuav tsum tau rau lub inverter tso zis tswj;lub inverter choj Circuit Court converts boosted DC voltage rau hauv AC voltage nrog ib tug ntau zaus sib npaug.
Inverter, tseem hu ua lub hwj chim regulator, tuaj yeem muab faib ua cov khoom siv hluav taws xob ywj pheej thiab kev siv kab sib txuas raws li kev siv inverter hauv lub tshuab hluav taws xob photovoltaic.Raws li lub waveform modulation txoj kev, nws yuav muab faib ua square wave inverter, kauj ruam yoj inverter, sine yoj inverter, thiab ua ke peb-theem inverter.Rau cov inverters siv hauv kab sib txuas, lawv tuaj yeem muab faib ua transformer-hom inverters thiab transformer-tsawg inverters raws li seb puas muaj ib qho transformer.Lub ntsiab technical parameters ntawm lub hnub ci photovoltaic inverter yog:
1. Rated tso zis voltage
Lub photovoltaic inverter yuav tsum muaj peev xwm tso tawm tus nqi ntsuas hluav taws xob nyob rau hauv qhov kev hloov pauv ntawm qhov kev tso cai ntawm DC input voltage.Feem ntau, thaum qhov ntsuas qhov tso zis hluav taws xob yog ib theem 220v thiab peb-theem 380v, qhov sib txawv ntawm qhov hluav taws xob sib txawv tau teev tseg raws li hauv qab no.
(1) Thaum khiav hauv lub xeev khov kho, feem ntau yuav tsum muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov voltage tsis tshaj ± 5% ntawm tus nqi ntsuas.
(2) Thaum lub load hloov pauv tam sim ntawd, qhov sib txawv ntawm qhov voltage tsis tshaj ± 10% ntawm tus nqi ntsuas.
(3) Raws li kev ua haujlwm ib txwm muaj, qhov tsis sib npaug ntawm peb-theem voltage tso tawm los ntawm inverter yuav tsum tsis pub tshaj 8%.
(4) Lub distortion ntawm voltage waveform (sine yoj) ntawm peb-theem tso zis feem ntau yuav tsum tsis txhob tshaj 5%, thiab ib-theem tso zis yuav tsum tsis txhob ntau tshaj 10%.
(5) Qhov sib txawv ntawm qhov zaus ntawm inverter tso zis AC voltage yuav tsum nyob rau hauv 1% raws li ib txwm ua hauj lwm tej yam kev mob.Cov zis voltage zaus teev nyob rau hauv lub teb chaws tus qauv Gb / t 19064-2003 yuav tsum nyob nruab nrab ntawm 49 thiab 51hz.
2. Thauj khoom fais fab
Qhov loj ntawm cov khoom siv fais fab qhia tau hais tias lub peev xwm ntawm lub inverter nqa ib qho inductive load lossis capacitive load.Nyob rau hauv cov xwm txheej ntawm sine yoj, lub zog thauj khoom yog 0.7 txog 0.9, thiab tus nqi ntsuas yog 0.9.Nyob rau hauv cov ntaub ntawv ntawm ib co load hwj chim, yog hais tias lub hwj chim ntawm lub inverter yog tsawg, qhov yuav tsum tau muaj peev xwm ntawm lub inverter yuav nce, uas ua rau tus nqi nce.Nyob rau tib lub sijhawm, lub zog pom tseeb ntawm AC Circuit Court ntawm lub tshuab hluav taws xob photovoltaic nce, thiab qhov hluav taws xob tam sim no nce.Yog hais tias nws loj, qhov poob yuav inevitably nce, thiab qhov system efficiency kuj yuav txo.
3. Rated tso zis tam sim no thiab ntsuas cov zis muaj peev xwm
Rated tso zis tam sim no yog hais txog qhov ntsuas tso zis tam sim no ntawm lub inverter nyob rau hauv qhov teev cov khoom siv hluav taws xob, chav tsev yog a;rated tso zis muaj peev xwm hais txog cov khoom ntawm cov zis tawm voltage thiab ntsuas cov zis tam sim no ntawm lub inverter thaum lub zog tso zis yog 1 (piv txwv li cov khoom siv hluav taws xob ntshiab), chav tsev yog kva lossis kw.
