Kev lag luam inverter feem ntau yog faib ua ob ntu: siab voltage thiab nruab nrab thiab qis voltage. Feem ntau ntawm cov downstream ntawm high voltage invertersyog cov tuam txhab lag luam loj thiab nruab nrab ntawm lub xeev nrog kev siv hluav taws xob siab. Raws li tus qauv ntawm kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob, kev ua lag luam tau khaws cia kev loj hlob tsis tu ncua.Raws li kev txhawb nqa ntawm "ob chav carbon" lub hom phiaj, lub zaus hloov pauv nrog kev hloov pauv ceev thiab lub zog yuav kuj ua rau muaj qhov chaw loj hlob raws li qhov tseem ceeb ntawm kev tswj lub cev muaj zog thiab kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.

Suav hom VS txawv teb chaws hom, qhov twg xaiv?

Txhawm rau kom nkag siab ntxiv txog kev siv cov tshuab ua haujlwm siab thiab cov tshuab hluav taws xob, peb tau sib tham nrog qee cov neeg siv kev lag luam.Thaum lub sij hawm kev sib txuas lus, yuav luag 100% ntawm cov tuam txhab tau qhia tias lawv tau paub txog qhov tseem ceeb ntawm kev txuag hluav taws xob thiab kev txo qis, thiab maj mam phasing tawm qee cov khoom siv lossis cov khoom lag luam uas muaj peev xwm tsim tawm, hloov cov khoom txuag hluav taws xob thiab txhim kho cov txheej txheem.

Nyob rau hauv cov txheej txheem ntawm kev txhim kho cov cuab yeej, ntau tus neeg siv yuav xub nug ib lo lus nug: qhov twg yog qhov zoo dua rau tus nqi ntawm kev yuav lub cev muaj zog lossis kev siv hluav taws xob ntau dua?

Los ntawm qhov kev xav ntawm luv luv nqi peev, tus nqi ntawm cov tshuab ua haujlwm siab yog siab dua li ntawm cov tsoos motors, thiab lub zog loj thiab kev thov ntawm cov khoom yuav cuam tshuam rau cov nqi tshwj xeeb. Nyob rau hauv ntev,high-efficiency motorsmuaj kev ua tau zoo dua, kev ua neej ntev dua, thiab muaj txiaj ntsig ntau dua nyob rau hauv cov qauv ntawm kev txuag hluav taws xob thiab txo qis emission. Tsav los ntawm cov cai thiab thev naus laus zis, kev ua haujlwm siab thiablub zog txuag motorstseem yuav txo cov nqi, thiab kev lag luam yuav tshwm sim ntxiv. Ntau thiab ntau cov neeg siv khoom txaus siab los nqis peev hauv cov khoom txuag hluav taws xob xws li cov tshuab ua haujlwm siab thiab cov inverter.

Cov ntaub ntawv siv:

Piv txwv li, siv 15kW lub cev muaj zog ua piv txwv, qhov ua tau zoo ntawm IE3 lub cev muaj zog yog li 1.5% siab dua li ntawm IE2 lub cev muaj zog ntawm qhov nruab nrab.Thaum lub sij hawm tag nrho lub neej voj voog ntawm lub cev muaj zog, kwv yees li 97% ntawm tus nqi yog los ntawm cov nqi hluav taws xob.

Yog li, piv txwv tias lub cev muaj zog khiav 3000 teev hauv ib xyoos, kev siv hluav taws xob muaj 0.65 yuan / kWh. Feem ntau, tom qab yuav lub IE3 lub cev muaj zog rau ib nrab xyoo, cov nqi hluav taws xob txuag tau tuaj yeem cuam tshuam qhov sib txawv ntawm cov nqi yuav khoom ntawm IE3 piv rau IE2 lub cev muaj zog.

Hauv peb cov kev sib txuas lus nrog qee tus neeg siv, peb kuj tau qhia tias kev siv cov inverters thiab motors tseem yuav suav nrog ntau qhov ntev, xws li kev teeb tsa software, kev sib raug zoo, qhov tshwj xeeb thiab cov haujlwm tshiab uas nws muaj. Raws li qhov no, peb tuaj yeem sib piv cov nqi. , yog li xaiv cov khoom tsim nyog.

Txawm hais tias daim ntawv thov ntawm lub cev muaj zog lossis lub inverter, nws kawg yog nyob ntawm qhov sib txawv ntawm cov txheej txheem, uas yog, lub zog txuag thiab qhov tseeb.Nyob rau hauv no hais txog, ntau tus neeg siv kuj tau hais tias nyob rau hauv cov nqe lus ntawm technology, qhov sib txawv ntawm domestic thiab txawv teb chaws hom nyob rau hauv lub qis-kawg thiab nruab nrab-kawg tsis loj heev, thiab cov zoo thiab technology kuj yog mature.Lub ntsiab sib txawv yog tus nqi, feem ntau txawv teb chaws hom yog 20% ​​mus rau 30% siab dua.Yog tias nws tsis tau teev tseg los ntawm tus neeg siv khoom qhov project, ntau tus neeg siv hais tias lawv tseem yuav xaiv cov khoom lag luam hauv tsev, uas yog tus nqi ntau dua.

Tom qab xyoo ntawm tsub zuj zuj, hauv zos inverter thiab lub cev muaj zog hom tau maj mam nthuav lawv cov lag luam sib koom. Tshwj xeeb, qee lub tshuab hluav taws xob hauv tsev yuav luag tsis muaj cov neeg sib tw thiab tsis muaj lub npe hloov pauv hauv qee qhov kev lag luam.Nyob rau hauv cov nqe lus ntawm zaus converters, qhov sib txawv ntawm tsawg-voltage zaus converters tau nqaim heev, thiab ntau lub tuam txhab tau txais yuav domestic zaus converters.Rau nruab nrab thiab high voltage zaus converters, kev ua lag luam feem ntawm cov lag luam hauv zos tau nce xyoo los ntawm lub xyoo, tab sis lawv tseem yog cov khoom lag luam txawv teb chaws.Ntawm cov khoom lag luam hauv tsev, cov kev pabcuam ntawm Inovance Technology thiab INVT yog qhov tseem ceeb dua.
