Imirasire y'izuba (PV) ni umugongo utaririmbye wa buri PV array. Bahinduranya imbaraga za DC kuva muri module kugeza muri inverters, kurinda sisitemu guhangayikishwa n’ibidukikije, na - iyo bahisemo cyangwa bagashyiraho nabi - barya bucece mubikorwa bya sisitemu kandi byizewe. Aka gatabo gasubiza ibibazo umunani byingenzi abaguzi, abashushanya, hamwe nitsinda ryamasoko bagomba kubaza kubyerekeye insinga za PV kugirango ubashe kwerekana, kugura, no kubungabunga sisitemu zitanga ingufu zasezeranijwe.
Ni ubuhe buryo insinga za PV kandi zitandukaniye he n'insinga z'amashanyarazi zisanzwe?
Imiyoboro ya PV ni imwe - umuyobozi, urumuri rwizuba - insinga zidashobora kwihanganira zagenewe umwihariko wa DC ifotora. Ugereranije na rusange - insinga zubaka zifite intego zifite umubyimba mwinshi UV / ozone / ubushyuhe - amakoti yihanganira, amanota ya DC agera kuri kV 1.5-22 (kubigezweho bigezweho), hamwe nubwubatsi burwanya igihe kirekire - igihe cyo hanze (guhindagurika, kuzenguruka ubushyuhe, guhura n’amazi). Ibipimo nka UL 4703 na EN 50618 bisobanura ibi byubaka nibikorwa bisabwa.
Nigute insinga zigira ingaruka kumusaruro w'ingufu - ni igihombo gipimwa?
Kurwanya abayobora no guhuza / guhuza imbaraga bitera kugabanuka kwa voltage no gutakaza ingufu bigabanya ingufu zitangwa, cyane cyane kumirongo miremire cyangwa hejuru - imirongo igezweho. Umuvuduko w'amashanyarazi ubarwa na VD=I × R × 2L (kurubu × kurwanya imiyoboro y'amashanyarazi × kuzenguruka - uburebure bw'urugendo). Ubunini buke cyangwa birebire byongera igihombo kandi birashobora kugabanya imikorere ya MPPT. Abashushanya mubisanzwe bahindura ingano yubuyobozi nuburyo bugabanya ibyo bihombo.
Nubuhe buryo nyamukuru bwo kunanirwa insinga za PV kandi bigira izihe ngaruka ku kwizerwa?
Uburyo bwingenzi bwo kunanirwa ni UV / ozone kwangirika kwamakoti, gusaza kwubushyuhe, ubushuhe / kwinjiza amazi yumunyu, kwangiza imashini (abrasion, hejuru ya - kwiyambura), hamwe nudahuza / kwangirika. Kunanirwa birashobora gutera akanya gato, ahantu hashyushye, arcs, hamwe na module ya catastrophique cyangwa gutsindwa kwa BOS - byose bigabanya umusaruro wingufu kandi bizamura ibiciro bya O&M. Ubushakashatsi bwakorewe hamwe nubushakashatsi burambye bwa BoS bwerekana ko guhitamo insinga bidakwiye no kwishyiriraho nabi bigenda bitera intandaro yo kudakora neza.
Ni ibihe bipimo n'ibizamini abaguzi bagomba gusaba?
Nibura vuga inama ya PV wire UL 4703 (US) cyangwa EN 50618 (Uburayi) cyangwa ibipimo bihwanye nigihugu; bisaba imbaraga za DC zipimishije (urugero, 1000-1500 VDC bitewe nuburyo bwa sisitemu), kurwanya izuba, igipimo cyubushyuhe, halogen - imitungo yubusa / flame retardant niba bisabwa na code yaho, hamwe na UV / ozone. Kubikorwa binini, saba raporo yikizamini cyuruganda, ibintu byakurikiranwe, hamwe no gusaza byihuse / C - AST cyangwa ibisubizo byikizamini bya wet / byumye byerekana ikoti.
Nibihe bisobanuro bifite akamaro cyane mugihe ugura (urutonde rwihuse)?
Amasoko afatika yo gutanga kugirango ashyire mubicuruzwa:
- Igipimo cya voltage:600 VDC / 1000 VDC / 1500 VDC nkuko bisabwa na sisitemu.
- Igipimo cy'ubushyuhe:ubushyuhe bukomeza gukora (urugero, dogere 90, dogere 105).
- UV / ozone irwanya & urumuri rw'izuba(urumuri rw'izuba - irwanya UL / EN).
- Ikoti:halogen - kubuntu nibisabwa; kurwanya umunyu / fungus niba ku nkombe cyangwa agrivoltaque.
- Umuyobozi:umuringa uhagaze neza kugirango ukomeze guhinduka no kunanirwa.
- Umusaraba - igice (igipimo):Ingano kugirango ugumane imbaraga za voltage no gushyuha mumipaka.
- Icyemezo:UL 4703, EN 50618, TÜV, cyangwa icya gatatu - raporo y'ibizamini by'ishyaka.
- Gukurikirana no kugerageza:ibyemezo by'urusyo, umubare witsinda, hamwe na raporo yikizamini cyo gusaza.
- Garanti & gutanga:ubuzima bwawe bwose hamwe no kuyobora - inshuro.
Nigute nshobora gupima insinga kugirango ngabanye igihombo ntakoresheje amafaranga menshi?
Koresha voltage - guta formulaire hamwe na conservateur yemerewe kwijana rya voltage (mubisanzwe 1-3% kumurongo wa DC). Shyiramo umugozi ntarengwa (Imp), uburebure bumwe - inzira yuburebure, hamwe no kurwanya abayobora (ohms kuri metero kumusaraba - igice). Amatsinda menshi yo gushushanya aringaniza igiciro cyuyobora kongerera ingufu buri mwaka; kwishyura mubisanzwe ni bigufi iyo kwiruka ari birebire cyangwa bigezweho ni byinshi. Kumibare nyayo, koresha ibikoresho byemewe hamwe nameza ya NEC / IEC kugirango barwanye abayobora. (Reba inkomoko ya calculatrice n'ingero zakozwe.)
Ni ubuhe buryo bwo gutanga amasoko hamwe na site - uburyo bwo kugenzura bugabanya ingaruka?
Ibikorwa byiza birimo: bisaba ibyemezo hamwe nibice bifitanye isano na raporo y'ibizamini; pre - ibicuruzwa byoherejwe byoherejwe (visual, resistance insulation); kugenzura ibipfunyika / kuranga kugirango wirinde impimbano; kuri - kugenzura urubuga kugirango wambure neza / torque hamwe ninkunga (irinde kwiruka ndende idashyigikiwe); hanyuma wohereze - kwishyiriraho IR / ikizamini cyo gukomeza. Shyiramo ibipimo byo kwemererwa mumasezerano kandi ugaragaze ingaruka zubufindo bwatsinzwe. Igenzura rya NREL hamwe ninganda zerekana ko kunanirwa kwinshi ari amakosa yo kwishyiriraho {{5} language ururimi rwamasezerano kandi urutonde rwa O&M rugabanya izo ngaruka.
Ni iki abaguzi bagomba kwishyura amafaranga yinyongera (ni ryari gukoresha amafaranga bifite ishingiro)?
Iyishyure ibintu bigabanya ibyago byubuzima cyangwa ibiciro bya O&M: igipimo cyinshi cya voltage ya DC (kugirango ushyigikire voltage yumurongo mwinshi hamwe nibice bike bya BOS), ikoti ryinshi UV / ozone - amakoti yihanganira ikirere gikaze, halogen - imikorere yumuriro wubusa aho code isaba, hamwe nabacuruzi bakurikirana + garanti ishyigikiwe nigeragezwa ryigenga. Ku nkombe, agrivoltaque, cyangwa kwibiza - ahantu hashobora kwibasirwa hasabwa amazi yumunyu namakuru yo kurwanya kwibiza - kwipimisha byihuse byerekana ko umunyu ushobora kugabanya ubuzima bwikoti. Iri vugurura akenshi ryishura binyuze mugihe cyo hasi na garanti ndende.
