Solar photovoltaic (PV) tambo ndiwo musana usina kusiiwa wePV array yese. Vanotamisa magetsi eDC kubva kumamodule kuenda kumainverters, vanochengetedza sisitimu kubva mukushushikana kwezvakatipoteredza, uye - kana vasarudzwa kana kuiswa zvisina kunaka - vanodya chinyararire mukuita kwehurongwa uye kuvimbika. Gwaro iri rinopindura mibvunzo misere inonyanya kukosha vatengi, vagadziri, uye zvikwata zvekutenga zvinhu zvinofanirwa kubvunza nezve PV tambo kuti iwe ugone kutsanangura, kutenga, uye kuchengetedza masisitimu anoburitsa simba rakavimbiswa.
Chii chaizvo chinonzi PV tambo uye dzinosiyana sei kubva kune akajairwa waya yemagetsi?
PV cables ndechimwe-conductor, chiedza chezuva-waya dzisingachinjiki dzakagadzirirwa chaizvo DC photovoltaic circuits. Zvichienzaniswa newaya-yechinangwa chekuvaka vane UV/ozone/temperature yakakora-mabhachi asingadziviriki, DC voltage ratings anosvika 1.5–2 kV (yemhando dzamazuvano), uye chivakwa chinopikisa kureba-kushushikana kwekunze (flexing, thermal cycles, kuratidzwa kwemvura). Mayero akaita seUL 4703 uye EN 50618 anotsanangura izvi zvekuvaka uye kuita zvinodiwa.
Ko tambo dzinokanganisa goho resimba sei - kurasikirwa kunoyerwa?
Conductor resistance uye connector/joint resistance zvinokonzeresa kudonha kwevoltige uye kupera simba izvo zvinoderedza simba rinounzwa, zvikuru parefu kana tambo dzakakwirira-zvino. Kudonha kwemagetsi kunoverengerwa neVD=I × R × 2L (ikozvino × conductor resistance × kutenderera-kureba kwerwendo). Yakashata saizi kana yakareba inomhanya inowedzera kurasikirwa uye inogona kuderedza MPPT kubudirira. Vagadziri vanogara vachikwirisa conductor saizi uye dhizaini kuti uderedze kurasikirwa uku.
Ndeapi makuru ekutadza modes ePV tambo uye anobata sei kuvimbika?
Makiyi ekutadza mamodhi eUV/ozone kushatiswa kwebhachi, kuchembera kwemafuta, kunyorova/kupinda kwemvura yemunyu, kukuvadzwa kwemuchina (abrasion, pamusoro-kubviswa), uye chinobatanidza kusawirirana/kuora. Kukundikana kunogona kugadzira intermittency, hotspots, arcs, uye catastrophic module kana BOS kukundikana - zvose zvinoderedza kugadzirwa kwesimba uye kukwidza O&M mari. Zvidzidzo zvemumunda uye kutsvagisa kweBoS kusimba kunoratidza kuti kusarudzwa kwetambo kwakashata uye kuisirwa zvisina kunaka kuri kudzokororwa zvikonzero zvekusashanda zvakanaka.
Ndeapi zviyero uye bvunzo dzinofanirwa kudiwa nevatengi?
Pashoma tsanangura PV waya musangano UL 4703 (US) kana EN 50618 (Europe) kana zvakafanana yenyika zviyero; zvinoda rated DC voltage (semuenzaniso, 1000–1500 VDC zvichienderana nemagadzirirwo egadziriro), chiedza chezuva, kuyera tembiricha, halogen-yemahara/inodzoreredza moto kana zvichidiwa nekodhi yeko, uye UV/ozone kuramba. Pamapurojekiti makuru, zvinoda marepoti ebvunzo dzefekitari, kurongeka kwezvinhu, uye kukurumidza kuchembera / C-AST kana nyoro/yakaoma bvunzo mhinduro yebhachi.
Ndeapi mafungidziro anonyanya kukosha kana uchitenga (nekukurumidza cheki)?
Inoshanda procurement specs yekusanganisira mumaodha ekutenga:
- Voltage rating:600 VDC / 1000 VDC / 1500 VDC sezvinodiwa nehurongwa.
- Kuyerwa kwetembiricha:kuenderera kwekushanda tembiricha (semuenzaniso, 90 degree, 105 degree).
- UV / ozone kuramba uye chiyero chezuva(chiedza chezuva-rinoshingirira paUL/EN).
- Jacket zvinhu:halogen-yemahara kana zvichidiwa; kuramba munyu/fungus kana iri pamahombekombe kana agrivoltaics.
- Kondakita:mhangura yakanatswa kuti ichengetedze kuchinjika uye kuramba kuneta.
- Muchinjikwa-chikamu (gauge):saizi kuchengetedza kudonha kwevoltage uye kudziyisa mukati memiganhu.
- Certification:UL 4703, EN 50618, TÜV, kana-vechitatu bvunzo mishumo.
- Traceability & batch bvunzo:zvigayo zvitupa, nhamba dzebatch, uye kuchembera bvunzo mishumo.
- Warranty & delivery:zvinotarisirwa kweupenyu hwose nenguva-zvinotungamira.
Ndinofanira kuyera sei tambo kuti ndideredze kurasikirwa pasina kushandisa zvakanyanya?
Shandisai voltage-kudonhedza fomula uye inotenderwa kudonha kwevoltage inobvumidzwa (kazhinji 1–3% yeDC string circuits). Isa iyo yakanyanya tambo yazvino (Imp), imwe-nzira kondakita kureba, uye conductor kuramba (ohms pamamita emuchinjiko-chikamu). Zvikwata zvakawanda zvekugadzira zvinoenzanisa mari yakawedzerwa conductor inopesana nekuwana simba kwegore; payback inowanzova ipfupi kana kumhanya kwakareba kana ikozvino kwakakwira. Kune nhamba chaidzo, shandisa maturusi akasimbiswa uye NEC/IEC matafura ekupikisa conductor. (Ona zvinyorwa zvemakarukureta uye mienzaniso yakashanda.)
Ndedzipi kutenga nekuongorora nzvimbo-maitiro anoderedza njodzi?
Maitiro epamusoro anosanganisira: kuda certification uye mabheti akasungirirwa kune mill test report; pre-yekutumira sampuli yekuyedza (kuona, kudzivirira kudzivirira); kutarisa kurongedza/chiratidzo kudzivirira manyepo; pa-kutariswa kwesaiti yekurura/torque yakakodzera uye tsigiro (usatsigire nzendo refu dzisina kutsigirwa); uye kutumira{{2}kuiswa IR/kuenderera mberi kuyedza. Sanganisira maitiro ekugamuchirwa muzvibvumirano uye tsanangura mhedzisiro yeakakundikana mijenya. NREL uye ongororo yeindasitiri inoratidza kukanganisa kwakawanda kukanganisa kwekuisa - mutauro wekondirakiti uye O&M chekilists inoderedza njodzi iyoyo.
Vatengi vanofanira kubhadhara chii chekuwedzera (kana kushandisa mari kwakakodzera)?
Bhadhara zvinhu zvinoderedza njodzi yehupenyu kana mitengo yeO&M: yakakwira DC voltage ratings (kutsigira matambo emagetsi epamusoro uye mashoma ezvikamu zveBOS), mabhachi akakora eUV/ozone-asingamirire mamiriro ekunze ane hukasha, halogen{1}}kushanda kwemoto pasina panodiwa kodhi, uye kutarisika kwevatengesi + waranti inotsigirwa nekuedzwa kwakazvimirira. Zvemahombekombe, agrivoltaic, kana pasi pemvura -nzvimbo dzine njodzi dzinokumbira ruzivo rwemvura ine munyu uye kunyura - kukurumidza kuyedza kunoratidza kuve munyu kunogona kupfupisa hupenyu hwejaketi. Aya makwidziridzo anowanzo bhadhara kuburikidza yakaderera downtime uye refu waranti.
