Yepamusoro-photovoltaicPV Cablechikamu chidiki chesolar system ine simba repamusoro pakuita kwehupenyu hwese, chengetedzo uye ROI. Kusarudza PV tambo yakakodzera - kondakita, insulation, uye zvinobatanidza - zvinoderedza kupera kwemagetsi, zvinodzivirira kukundikana uye zvinobatsira kusangana nemakodhi (NEC/IEC/UL). Gwaro iri rinopindura mibvunzo misere yakajairika inobvunzwa nevatengi, vanogadzira uye vanoisa, uye inopa rondedzero yekutenga inoshanda.
Chii chaizvo chinonzi "PV tambo" uye dzakasiyana sei kubva kune yakajairika waya yemagetsi?
PV cables isingle-conductor, chiedza chezuva{1}}waya dzisingachinjiki dzakagadzirirwa kubatanidza maPV modules uye DC side rePV masisitimu. Vanowanzo shandisa maconductors emhangura akaiswa tinned uye -linked polyolefin (XLPO/XPLE) kana imwe UV/heat -inodzivirira kudzivirira. Matambo ePV akaiswa patembiricha yepamusoro-soro, -kuratidzwa kwezuva, uye kureba kunze kweupenyu hwose - zvisingadiwi pawaya dzekuvaka. Mitemo yakadaiIEC 62930uyeUL 4703tsanangura kuvaka uye bvunzo zvinodiwa zvePV tambo.
Ndeapi zviyero uye zvitupa zvandinofanira kuda kana ndichitenga PV tambo?
Inoda tambo dzinofambirana nezviyero zvePV zvazvino uye-maki ebvunzo emapato:
IEC 62930(yepasi rose PV cable standard) - inoshandiswa zvakanyanya kunze kweUS kune 1.5 kV DC yakayereswa tambo. webstore.iec.ch

Ndinokura sei tambo dzePV (AWG/mm²) - zvinhu zvipi zvine basa?
Cable saizi yezviyereso zvipingamupinyi zvitatu: ampacity (yazvino chiyero), kudonha kwevoltage, uye zvemakanika / kuisirwa zvipingaidzo. Shandisa iyohombeconductor inodiwa neampacity kana voltage -kudonha mitemo. Zvinhu zvakakosha: yakanyanya tambo yazvino (kana inverter yekupinda ikozvino), DC system voltage, conductor tembiricha chiyero, kureba kwekumhanya (kunokanganisa kudonha kwevoltage), uye tembiricha ambient saiti (ampacity derating). MaLab emunyika uye nhungamiro yeindasitiri inosimbisa kugara uchitarisa ampacity uye kudonha kwevoltage - wobva washandisa conductor yakakura. Kune PV yekugara, vanoisa vanowanzo simudza imwe AWG kudzikisa kudonha kwemagetsi (semuenzaniso, AWG 10 → AWG 8).Zano rinoshanda:chinangwa cheKuderera kana kuenzana ne1.5-2% kudonha kwevoltage pane refu DC inomhanya; kune dzakakosha refu arrays, recalc pane inotarisirwa max ekushanda tembiricha.
Ndeipi tembiricha, voltage uye zviyero zvezvakatipoteredza zvandinofanira kuda?
Zviyero zvishoma zvinogamuchirwa zvinoenderana nekodhi uye nzvimbo yeprojekiti, asi zvinowanzoitika:
Tembiricha:Rated for at least90 degreeinoenderera (yakawanda PV waya dzakatarwa 90-125 dhigirii). UL 4703 inotsanangura sarudzo dzinosvika 150 dhigirii kune zvimwe zvivakwa. UL Standards Store
Voltage:Zvakajairwa DC ratings ndizvo600 V, 1.0 kV uye 1.5 kV(yepamusoro-masisitimu emagetsi ari kuwedzera kuwanda). Shandisa tambo yakayerwa pamusoro peiyo system yakanyanya DC voltage. webstore.iec.ch+1

Akakosha zvakadii maconnectors (MC4 nezvimwewo), uye ndeapi matambudziko aanokonzera?
Makonitani chinangwa-chakakosha. Zvisizvo kana zvisina kuisirwa zvibatanidza zvinokonzeresa kutadza kwePV kubatana uye isingawanzo asi yakakomba moto. Kuyedzwa kwakazvimirira uye machena mapepa anoratidza hunhu hwekubatanidza, dhizaini yekubata uye kugadzirwa kunopesvedzera kuvimbika. Shandisa marambiki ekubatanidza mabhureki, crimp tooling, uye ongorora torque uye kuisa. Shandisa O&M yekuongorora zvirongwa zvekuona discoloration, kudziyisa, kana kupinda kwemvura.
Ndeapi magadzirirwo etambo akanakira hupenyu hurefu uye yakaderera kugadzirisa?
