IiCables zeSolar Photovoltaic: Amacandelo abalulekileyo kuwo onke amaFakelo eSolar

{0}umgangatho ophezulu we-photovoltaicIntambo yePVyinxalenye encinci yesixokelelwano selanga esinempembelelo enkulu ekusebenzeni kwexesha lokuphila, ukhuseleko kunye ne-ROI. Ukukhetha intambo ye-PV efanelekileyo - i-conductor, i-insulation, kunye nezihlanganisi - kunciphisa ukulahlekelwa kwamandla, kuthintela ukusilela kwaye inceda ukuhlangabezana neekhowudi (NEC/IEC/UL). Esi sikhokelo siphendula eyona mibuzo isibhozo ixhaphakileyo abathengi, abaqulunqi nabafakeli abayibuzayo, kwaye inika uluhlu lokuthenga olusebenzayo.

Yintoni kanye kanye "iintambo zePV" kwaye zahluke njani kwiintambo zombane eziqhelekileyo?

Iintambo ze-PV zizodwa-i-conductor, ukukhanya kwelanga{1}}iingcingo ezikwaziyo ukumelana neengcingo ezenzelwe ukudibanisa iimodyuli zePV kunye necala le-DC leenkqubo zePV. Ngokwesiqhelo basebenzisa inkonkxa, iikhondatha zekopolo ezibotshelelweyo kunye-ne-polyolefin edityanisiweyo edityanisiweyo (XLPO/XPLE) okanye enye i-UV/ubushushu{4}}ekwaziyo ukugquma. Iintambo ze-PV zithelekelwe amaqondo obushushu aqhubekayo aphezulu, ngokuthe ngqo{6}ukukhanya kwelanga, kunye nobomi obude ngaphandle - kwiipropati ezingafunekiyo kwiingcingo zesakhiwo eziqhelekileyo. Imigangatho efanaIEC 62930kwayeUL 4703chaza iimfuno zokwakha kunye novavanyo lwentambo yePV.

Yeyiphi imigangatho kunye neziqinisekiso endizifunayo xa ndithenga intambo yePV?

Funa iintambo ezihambelanayo nemigangatho yangoku yePV kunye -namanqaku ovavanyo lomntu wesithathu:

IEC 62930(umgangatho wentambo yePV yamazwe ngamazwe) - isetyenziswa kakhulu ngaphandle kwe-US kwiintambo ezireyithiweyo ze-1.5 kV DC. webstore.iec.ch

EN 50618(IYurophu) - ixela i-halogen{1}}yasimahla, iUV{2}}iintambo zePV ezikwaziyo ukuguquguquka. Izisombululo ze-UL

UL 4703(US) - umgangatho we-photovoltaic wire, ugubungela ubushushu kunye nokulinganisa umbane kunye nokumelana nokukhanya kwelanga. I-UL Standards Store

Ndizenza njani ubukhulu beentambo zePV (AWG/mm²) - zeziphi izinto ezibalulekileyo?

Imilinganiselo yekheyibhile ilinganisa imiqobo emithathu: ampacity (umthamo wangoku), ukuhla kwamandla ombane, kunye nemiqobo yomatshini/yofakelo. Sebenzisa iinkuluumqhubi ofunwa yi-ampacity okanye amandla ombane{0}}imithetho yokwehla. Izinto ezibalulekileyo: ubuninzi bentambo yangoku (okanye i-inverter input current), i-voltage ye-DC yenkqubo, ukulinganisa ubushushu bomqhubi, ubude bokuqhuba (kuchaphazela ukuhla kwamandla ombane), kunye nobushushu bendawo yendawo (i-ampacity derating). Iilebhu zelizwe kunye nesikhokelo soshishino sigxininisa rhoqo ukujonga ubungakanani kunye nokuhla kwamandla ombane - emva koko usebenzise i-conductor enkulu. Kwi-PV yokuhlala, abafakeli badla ngokunyusa i-AWG enye ukunciphisa ukuhla kwamandla ombane (umz., AWG 10 → AWG 8).Ingcebiso esebenzayo:nenjongo yokuhla kwe-voltage engaphantsi okanye elingana ne-1.5–2% kwii-DC ezide; kuluhlu olude olubalulekileyo, i-recalc kubushushu obulindelekileyo bokusebenza.

Ngawaphi amaqondo obushushu, amandla ombane kunye nokusingqongileyo ekufuneka ndiwafune?

Ubuncinane bokulinganisa okwamkelekileyo kuxhomekeke kwikhowudi kunye nendawo yeprojekthi, kodwa iimfuno eziqhelekileyo:

Ubushushu:Ilinganiswe ngobuncinci90 degreengokuqhubekayo (iingcingo ezininzi ze-PV zilinganiswe i-90-125 degree). I-UL 4703 ichaza iinketho ukuya kuthi ga kwi-150℃kwezinye izakhiwo. I-UL Standards Store

I-Voltage:Iireyithingi eziqhelekileyo zeDC zi600 V, 1.0 kV kunye ne-1.5 kV(eziphezulu-iinkqubo zamandla ombane ziya zixhaphaka). Sebenzisa intambo ebekwe ngaphezulu kowona mbane uphezulu wenkqubo weDC. webstore.iec.ch{5}}

UV kunye nokumelana nemozulu:I-Insulation kufuneka ikwazi ukumelana nokukhanya kwelanga kunye ne-UV{1}}zinze eluphahleni, imitsi evezwayo kunye nemingcwabo ethe ngqo ukuba iyafuneka. Uvavanyo lwemigangatho (IEC / EN / UL) ye-UV kunye nokuguga kwe-thermal

Zibaluleke kangakanani iziqhagamshelo (MC4 njl.njl.), kwaye zeziphi iingxaki ezizibangelayo?

Iziqhagamshelo zibalulekile-. Iziqhagamshelo ezingalunganga okanye ezingafakwanga kakuhle zingunobangela ophambili wokusilela koqhagamshelo lwePV kunye nemililo enqabileyo kodwa eyingozi. Uvavanyo oluzimeleyo kunye namaphepha amhlophe abonisa umgangatho wokudibanisa, uyilo loqhagamshelwano kunye nokusebenza kukuchaphazela kakhulu ukuthembeka. Sebenzisa iimpawu zokudibanisa eziqinisekisiweyo, izixhobo ezifanelekileyo zecrimp, kwaye uhlole i-torque kunye nokufakwa. Ukuphumeza izicwangciso zokuhlola i-O&M ukuze ubone umbala, ukufudumeza, okanye ukungena kwamanzi.

Loluphi ulwakhiwo lweentambo ezilungele ubomi obude kunye nokugcinwa okuphantsi?

Iikhondaktha zethusi ezinkonkxiweyo, ezinemisonto ecolekileyo(i-tinning inciphisa umhlwa kwaye yenza lula ukupheliswa). kukacable.com

Umnqamlezo-uqhagamshelwe ipololefin (XLPO/XPLE)okanye iUV elinganayo-izinzile, ihalogen{1}i-insulation yasimahla yophahla oluphezulu/imitsi evezwayo. Izisombululo ze-UL

Kabini-ukhetho olugqunyiweyo okanye ngaphezulu{1}}kwebhatyixa ukubaleka kuxhomekeke ekunxityweni ngoomatshini okanye kungcwatywa ngokuthe ngqo.

Umzi-mveliso-odityanisiweyo wemisila yehagu okanye{1}}ngaphambili iintambo zokubopha eziphelisiwe zinokucutha iimpazamo zasendle. Ibhalansi yeendleko xa ithelekiswa nomngcipheko: ikhebula engabizi kakhulu namhlanje inokubiza ngaphezulu ngokutshintshwa kunye nexesha lokuphumla.
