Ib, Photovoltaic systems boom
Nrog rau kev nce ntxiv ntawm kev tiv thaiv ib puag ncig thoob ntiaj teb, cov tshuab photovoltaic tau siv dav hauv ntau qhov chaw.Hauv kev lag luam hluav taws xob, cov tshuab hluav taws xob photovoltaic tuaj yeem tsis tsuas yog muab hluav taws xob rau cov nroog, tab sis kuj muab kev pabcuam teeb pom kev zoo thiab kev sib txuas lus rau cov chaw nyob deb.Nyob rau tib lub sijhawm, cov tshuab photovoltaic muaj cov nqi qis thiab cov nqi khiav lag luam qis, yog li lawv tau nyiam los ntawm ntau thiab ntau lub tuam txhab thiab tsoomfwv cov koom haum.
二 、 Photovoltaic inverters muaj teeb meem kom kov yeej
Lub photovoltaic inverter yog ib qho cuab yeej uas hloov cov tam sim no ncaj qha tsim los ntawm photovoltaic panels rau hauv alternating tam sim no.Nws saib xyuas qhov voltage thiab tam sim no tso zis los ntawm photovoltaic panels los ntawm lub siab tshaj plaws lub hwj chim taw tes nrhiav algorithm, paub qhov voltage nce thiab poob ntawm ncaj qha tam sim no, thiab converts nws mus rau hauv ib tug ruaj khov direct tam sim no fais fab mov.Tom ntej no, lub inverter converts DC lub zog rau AC lub zog siv high-frequency pulse width modulation technology, thiab smooths nws los ntawm cov zis lim los xyuas kom meej qhov zoo thiab stability ntawm cov zis tam sim no.Thaum kawg, lub inverter txuas cov zis AC fais fab mus rau daim phiaj hluav taws xob kom tau raws li cov tsev neeg lossis cov khoom siv hluav taws xob.Nyob rau hauv txoj kev no, photovoltaic inverters ua lub luag haujlwm tseem ceeb hauv kev hloov lub hnub ci zog rau hauv hluav taws xob siv tau.
Tam sim no, hom 1000 ~ 2200W photovoltaic inverter siv nyob rau hauv qhov kawg ntawm photovoltaic fais fab tiam system muaj lub siab tshaj plaws tso zis voltage txog li 580V.Txawm li cas los xij, tam sim no 500V tso zis capacitor tsis tuaj yeem ua tau raws li qhov xav tau ntawm photovoltaic inverters.Ntawm lawv, txhuas electrolytic capacitors ua lub luag haujlwm tseem ceeb, uas tuaj yeem tsis tsuas yog muab cov lim dej tsim nyog thiab khaws cia, tab sis kuj ua kom muaj kev ntseeg siab thiab ua haujlwm ntawm tag nrho cov kab ke.Yog tias qhov tso zis hluav taws xob tsis txaus, nws yuav ua rau lub capacitor cua sov, tawg, thiab thaum kawg yuav puas.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog ntau yam thaum xaiv cov khoom siv hluav taws xob electrolytic, thiab xaiv cov khoom tsim nyog tshaj plaws los xyuas kom meej tias kev ua haujlwm zoo ntawm lub cev thiab tau txais kev ua haujlwm zoo tshaj plaws.
三、Yongming high-voltage lead-type capacitors daws qhov "high voltage" xwm txheej ceev
Yuav kom daws tau qhov teeb meem high-voltage ntawm photovoltaic inverters, Shanghai Yongming launched high-voltage lead-type LKZ series txhuas electrolytic capacitor.Tsev neeg muaj cov yam ntxwv ntawm kev ua tau zoo thiab ua haujlwm dhau ntau yam ntawm cov khoom siv hluav taws xob, suav nrog cov hluav taws xob siab txog li 580V.Kev ua tau zoo ntawm LKZ series capacitors tuaj yeem txhim kho kev ruaj ntseg thiab kev ua haujlwm ntawm photovoltaic inverters thiab muab cov neeg siv khoom nrog cov kev daws teeb meem zoo tshaj plaws.
1, Super muaj zog surge thiab cuam tshuam tsis kam: LKZ series txhuas electrolytic capacitors tuaj yeem ncav cuag 600V voltage, uas tuaj yeem yooj yim tuav lub ncov voltage thiab loj tam sim no thaum tso zis.
2 、 Tsis tshua muaj kev tiv thaiv sab hauv thiab zoo dua cov yam ntxwv ntawm qhov kub thiab txias: Piv nrog Japanese capacitors ntawm tib lub ntsiab lus, lub impedance ntawm Yongming capacitors raug txo los ntawm 15% ~ 20%, uas ua kom qhov kub thiab txias, loj ripple kuj thiab - 40 ℃ kev ua tau zoo ntawm lub capacitor thaum ua haujlwm.Cov yam ntxwv kub qis, kom lub capacitor yuav tsis poob thaum ntxov hauv kev ua haujlwm ntev.
3 、 Lub peev xwm siab dua: Yongming aluminium electrolytic capacitors muaj ntau dua 20% loj dua Japanese capacitors ntawm tib qhov tshwj xeeb thiab qhov loj me, muaj peev xwm ntau dua thiab cov nyhuv lim dej zoo dua;Nyob rau tib lub sijhawm, raws li tib lub zog yuav tsum tau ua, siv Yongming Lub peev xwm loj dua electrolytic capacitors tuaj yeem txo cov neeg siv khoom tus nqi raws li qhov muaj peev xwm.
4 、 Kev ntseeg siab: Yongming lub electrolytic capacitors muab kev lees paub ntau dua rau kev ruaj ntseg thiab kev ntseeg tau ntawm cov khoom siv hluav taws xob tseem ceeb xws li photovoltaic inverters, ua rau kev ua haujlwm ntawm tag nrho cov photovoltaic system zoo heev.
Rated voltage: 550 ~ 600V
Muaj peev xwm ntau: 82 ~ 220μF
Ua haujlwm kub: -40 ~ 105 ℃
Lifespan: 12000 ~ 15000H
四 、 Tsim cov khoom siv hluav taws xob zoo hauv tsev thiab nce mus rau kev lag luam thoob ntiaj teb
Raws li ib tug domestic innovative capacitor, Yongming cov kua txhuas txhuas electrolytic capacitor muaj qhov zoo tshaj plaws nyob rau hauv daim ntawv thov ntawm photovoltaic inverters, muab ib tug muaj zog guarantee rau stability ntawm lub photovoltaic system, thiab nws cov kev ua tau zoo yog piv rau cov Japanese capacitors..
