Nigute ushobora guhitamo insinga za Photovoltaque kuri sisitemu ya Photovoltaque?

Igiciro cyumuringa cyazamutse vuba, kandi igiciro cyinsinga nacyo cyazamutse.Mubiciro byose bya sisitemu ya Photovoltaque, igiciro cyibikoresho nkainsinga z'amashanyarazina switch yarenze iya inverter, kandi iri munsi yibigize nibishyigikirwa.Iyo tubonye igishushanyo cya sosiyete ishushanya kandi tuzi ibipimo byubwoko bwinsinga, ubunini, ibara, nibindi, dushobora gutangira kugura nurutonde.Nyamara, hari ubwoko bwinshi bwinsinga, kandi abakoresha benshi bayobewe nubwoko bwinshi bwinsinga.Ninde uruta?

Mugihe duhitamo umugozi wamafoto, tugomba mbere na mbere kureba ibintu bibiri: kiyobora hamwe nicyuma.Igihe cyose ibi bice byombi ari byiza, ubwiza bwinsinga bugaragara ko bwizewe.

1. Umuyobozi

Andika insulasiyo ya kabili kugirango ugaragaze insinga z'umuringa imbere, uyu niwe uyobora.Turashobora gusuzuma ubuziranenge bwabayobora duhereye kubintu bibiri:

01. ibara

Nubwo abayobora bose bita "umuringa", ntabwo ari umuringa wera 100%, kandi hazaba harimo umwanda.Uko umwanda urimo, niko ububi bwuyobora.Ingano yimyanda ikubiye mubayobora izagaragarira mubara.

Umuringa mwiza mwiza witwa "umuringa utukura" cyangwa "umuringa utukura" -kuko izina ribigaragaza, ibara ryubwoko bwumuringa ni umutuku, umutuku, umutuku-umutuku, umutuku wijimye.

Umuringa mubi, niko ibara ryoroha kandi ni umuhondo, aribyo bita "umuringa."Umuringa umwe ni umuhondo woroshye-ibintu byanduye byuyu muringa bimaze kuba hejuru cyane.

Bimwe muribi byera, izi ni insinga zateye imbere.Insinga z'umuringa zometseho amabati, impamvu nyamukuru ni ukubuza umuringa okiside kugirango ube patina.Imikorere ya patina irakennye cyane, byongera ubukana no kugabanuka.Byongeye kandi, gutobora insinga z'umuringa birashobora kandi kubuza reberi yiziritse kudafatana, kwirabura no gukomera kwintangiriro, no kunoza ubushobozi bwayo.Umugozi wa Photovoltaic DC ni insinga z'umuringa.

02. ubunini

Iyo diameter ya wire ari imwe, umubyimba mwinshi, niko imbaraga zoroha-iyo ugereranije ubunini, gusa uwuyobora agomba kugereranywa, kandi nubunini bwurwego rukingira ntibigomba kongerwaho.

Gerageza gukoresha imirongo myinshi ya wire yoroheje.Hariho insinga imwe yibanze muri kabel, yitwa insinga imwe yibanze, nka BVR-1 * 6;hari insinga nyinshi zingenzi mumigozi, nka YJV-3 * 25 + 1 * 16, Yitwa insinga nyinshi;buri cyuma cyibanze kigizwe ninsinga nyinshi z'umuringa kandi cyitwa insinga nyinshi, zoroshye kandi zikwiranye na sisitemu yo gufotora.Umugozi wumugozi umwe urashobora guhonyorwa kuri terefone, ariko umugozi umwe wumugozi urakomeye kandi ntukwiriye gushyirwaho ahantu hamwe na radiyo ntoya.Ku nsinga zinyuranye zifite metero kare kare 16, birasabwa gukoresha insinga za kabili hamwe nintoki za crimping terminal.Ku nsinga zinyuranye zifite metero kare 16, birasabwa gukoresha itumanaho ryihariye rya hydraulic clamps.

2. Urwego

Igice cya reberi hanze yumugozi nicyerekezo cyicyuma.Igikorwa cyayo ni ugutandukanya umuyoboro ufite ingufu ziva hanze, kurinda ingufu z'amashanyarazi gutembera hanze, no gukumira abantu bo hanze guhungabana amashanyarazi.Mubisanzwe, uburyo butatu bukurikira burashobora gukoreshwa mugupima ubuziranenge bwurwego:

1) Koraho, kora hejuru yuburumbuke bworoshye ukoresheje amaboko yawe.Niba ubuso butajegajega, byerekana ko uburyo bwo kubyaza umusaruro urwego rwimikorere ikennye kandi bukunze kwibeshya nkumuriro w'amashanyarazi.Kanda urwego rukingira urutoki rwawe, kandi niba rushobora kongera kwihuta, birerekana ko urwego rukingira rufite umubyimba mwinshi kandi rukomeye.

)Niba nta kimenyetso kiri hejuru yinsinga, byerekana ko insinga ifite ubukana bwiza.Niba hejuru yinsinga ifite indente igaragara cyangwa yera cyane, byerekana ko insinga ifite ubukana bubi.Gushyingurwa mu butaka igihe kirekire, biroroshye gusaza, gucika intege, kandi byoroshye kumeneka amashanyarazi mugihe kizaza.

3) Gutwika.Koresha urumuri kugirango ukomeze gutwika insinga kugeza igihe insinga zifata umuriro.Noneho uzimye urumuri hanyuma utangire igihe-niba insinga ishobora guhita izimya mumasegonda 5, irerekana ko insinga ifite umuriro mwiza.Bitabaye ibyo, byaragaragaye ko ubushobozi bwa flame retardant ya wire butageze kurwego rusanzwe, umuzenguruko uremerewe cyangwa umuzunguruko byoroshye gutera umuriro.

3. Ubuhanga bwo gukoresha amashanyarazi ya Photovoltaque

Umurongo wa sisitemu ya Photovoltaque igabanijwemo igice cya DC nigice cya AC.Ibi bice byombi byumurongo bigomba kuba bitandukanye.Igice cya DC gihujwe nibigize, naho igice cya AC gihujwe na gride.Hano hari insinga nyinshi za DC mumashanyarazi manini kandi manini.Kugirango byoroherezwe kubungabunga ejo hazaza, nimero yinsinga zinsinga zigomba gufungwa.Tandukanya insinga zikomeye kandi zidakomeye.Niba hari insinga z'ikimenyetso, uzereke inzira zitandukanye kugirango wirinde kwivanga.Birakenewe gutegura imiyoboro hamwe nikiraro, gerageza ntugaragaze insinga, kandi insinga zitambitse kandi zihagaritse zizasa neza mugihe ziyobowe.Gerageza kutagira umugozi uhuza imiyoboro hamwe nikiraro, kuko kubungabunga ntibyoroshye.

Muri sisitemu ya Photovoltaque, imishinga yo murugo nimishinga mito mito yinganda nubucuruzi, imbaraga za inverter ziri munsi ya 20kW, naho agace kambukiranya umugozi umwe kari munsi ya kare 10.Birasabwa gukoreshainsinga z'izuba nyinshi.Muri iki gihe, ntabwo bigoye gushira kandi byoroshye kuyobora;Imbaraga zihindura ziri hagati ya 20-60kW, kandi igice cyambukiranya igice cyumugozi umwe kirenze kare kare 10 na munsi ya kare 35, gishobora gutoranywa ukurikije uko urubuga rumeze;niba imbaraga za inverter zirenze 60 kWt kandi igice cyambukiranya igice cyumugozi umwe kirenga kare kare 35, birasabwa guhitamo insinga imwe yibanze byoroshye gukora kandi bihendutse kubiciro.
