Inverter yog ib hom kev hloov hluav taws xob uas tsim los ntawm cov khoom siv semiconductor, feem ntau yog siv los hloov DC lub zog rau hauv AC lub zog, feem ntau yog tsim los ntawm boost circuit thiab inverter choj Circuit Court.Lub boost Circuit Court boosts DC voltage ntawm lub hnub ci cell mus rau DC voltage xav tau los ntawm inverter tso zis tswj;Lub inverter choj Circuit Court converts boosted DC voltage rau hauv cov zaus AC voltage sib npaug.
Inverter, tseem hu ua lub hwj chim regulator, tuaj yeem muab faib ua ob hom kev ywj pheej fais fab mov thiab daim phiaj-txuas raws li kev siv inverter hauv photovoltaic zog tsim system.Raws li lub waveform modulation hom, nws yuav muab faib ua square yoj inverter, kauj ruam yoj inverter, sine yoj inverter thiab ua ke peb-theem inverter.Rau lub inverter siv nyob rau hauv daim phiaj-txuas system, raws li lub xub ntiag los yog tsis muaj transformer yuav muab faib ua transformer hom inverter thiab transformer hom inverter.Lub ntsiab technical parameters ntawm hnub ci photovoltaic inverter yog:
1. Rated tso zis voltage
Lub pv inverter yuav tsum muaj peev xwm tso tawm qhov ntsuas hluav taws xob nyob rau hauv qhov kev tso cai hloov pauv ntau ntawm cov lus qhia tawm dc 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 ntsuas hluav taws xob muaj cov kev cai hauv qab no.
(1) Hauv kev ua haujlwm ruaj khov, qhov sib txawv ntawm qhov sib txawv voltage feem ntau yuav tsum tsis pub tshaj ± 5% ntawm tus nqi ntsuas.
(2) Voltage deviation yuav tsum tsis pub tshaj ± 10% ntawm tus nqi ntsuas nyob rau hauv cov ntaub ntawv ntawm load hloov.
(3) Raws li kev ua haujlwm ib txwm muaj, qhov tsis sib npaug ntawm peb-theem voltage tso tawm ntawm lub inverter yuav tsum tsis pub tshaj 8%.
(4) Lub distortion ntawm peb-theem tso zis voltage waveform (sine yoj) yuav tsum tsis txhob ntau tshaj 5%, thiab ib-theem tso zis yuav tsum tsis txhob ntau tshaj 10%.
(5) Lub inverter tso zis AC voltage zaus nyob rau hauv ib txwm ua hauj lwm tej yam kev mob nws deviation yuav tsum nyob rau hauv 1%.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, load zog yam
Lub peev xwm ntawm lub zog qhia tau hais tias lub peev xwm ntawm lub inverter nrog inductive load lossis capacitive load.Nyob rau hauv sine yoj tej yam kev mob, lub load hwj chim yam li ntawm 0.7 mus rau 0.9, thiab qhov ntsuas yog 0.9.Nyob rau hauv cov ntaub ntawv ntawm ib tug tej yam load hwj chim, yog hais tias lub hwj chim ntawm lub inverter yog tsawg, qhov yuav tsum tau inverter muaj peev xwm yuav nce, ua rau ib tug nce nyob rau hauv tus nqi, nyob rau tib lub sij hawm, lub pom meej hwj chim ntawm lub photovoltaic system AC voj nce, lub voj tam sim no nce, qhov poob yuav inevitably nce, thiab qhov system efficiency yuav txo.
3. Rated tso zis tam sim no thiab muaj peev xwm
Rated tso zis tam sim no hais txog qhov ntsuas qhov tso zis tam sim no ntawm lub inverter nyob rau hauv qhov teev cov khoom siv hluav taws xob ntau (unit: A).Rated tso zis muaj peev xwm yog cov khoom ntawm cov ntsuas tso zis voltage thiab ntsuas cov zis tam sim no ntawm lub inverter thaum lub zog tso zis yog 1 (piv txwv li, lub siab dawb huv load), hauv KVA lossis kW
