I-Solar Farm-Simplified trunk cable design yenza ukufakwa kube lula futhi kunciphisa izindleko zizonke

Eminyakeni yamuva nje, isidingo samandla elanga siye sakhula njengenye indlela eluhlaza esikhundleni sokuphehlwa kwamandla kagesi asuselwa kuphethiloli, futhi inkambiso yamadivayisi aphehla amandla elanga ibilokhu ibheke kumasistimu anonyawo olukhudlwana namandla okukhiqiza amakhulu.
Kodwa-ke, njengoba amandla kanye nobunzima bamapulazi elanga buqhubeka bukhula, izindleko ezihlobene nokufakwa kwazo, ukusebenza nokugcinwa kwazo ziyanda.Ngaphandle uma isistimu iklanywe ngendlela efanele, njengoba usayizi wesistimu ukhula, ukulahlekelwa okuncane kwamandla kagesi kuzokwanda.Uhlelo lwe-TE Connectivity's (TE) Solar Customizable Trunk Solution (CTS) luncike enkambweni yesakhiwo samabhasi amakhulu (okuchazwe ngezansi).Lo mklamo unikeza enye indlela ephumelelayo ezindleleni zendabuko, ezithembele emakhulwini okuxhumana kwebhokisi lesihlanganisi ngasinye kanye nezikimu zezintambo eziyinkimbinkimbi.
I-TE's Solar CTS isusa ibhokisi lesihlanganisi ngokubeka ipheya lezintambo ze-aluminium phansi, futhi ingaxhuma kalula izintambo ze-TE nesixhumi sethu esinelungelo lobunikazi se-Gel Solar Insulation Piercing (GS-IPC) kunoma ibuphi ubude bentambo.Kusukela endaweni yokubuka yokufaka, lokhu kudinga izintambo ezimbalwa kanye nezindawo zokuxhuma ezimbalwa ukuze kwakhiwe esizeni.
Uhlelo lwe-CTS lunikeza ukonga okusheshayo kubanikazi besistimu nabaqhubi mayelana nokunciphisa izindleko zezintambo nezekhebula, ukunciphisa isikhathi sokufaka nokusheshisa ukuqaliswa kwesistimu (ukulondoloza okungu-25-40% kulezi zigaba).Ngokunciphisa ngokuhlelekile ukulahlekelwa kwamandla kagesi (ngaleyo ndlela kuvikela amandla okukhiqiza) kanye nokunciphisa umthwalo wokulungisa isikhathi eside nokuxazulula izinkinga, kungase futhi kuqhubeke nokonga imali phakathi nawo wonke umjikelezo wokuphila wepulazi lelanga.
Ngokwenza lula ukuxazululwa kwezinkinga nokulungiswa kwendawo, idizayini ye-CTS iphinde ithuthukise ukwethembeka kwesistimu kanye nokusebenza kahle kwabasebenzi bamapulazi elanga elikhulu.Nakuba isistimu izuza emicabangweni yedizayini emisiwe neyemojuli, ingase futhi yenziwe ngendlela oyifisayo ukubhekana nezimo eziqondene nesayithi nokucatshangelwa kobunjiniyela.Isici esibalulekile salo mkhiqizo ukuthi i-TE isebenza eduze namakhasimende ukuze inikeze ukwesekwa okuphelele kobunjiniyela.Ezinye zalezi zinsizakalo zifaka izibalo zokwehla kwamandla kagesi, ukwakheka kwesistimu okusebenzayo, ukulayishwa kwe-inverter okulinganiselwe, nokuqeqeshwa kwabafaki esizeni.
Kunoma iyiphi isistimu yamandla elanga elivamile, yonke indawo yokuxhuma-kungakhathaliseki ukuthi iklanywe kahle noma ifakwe kahle kangakanani-izokhiqiza ukumelana okuncane (ngakho-ke ukuvuza kwamanje kanye ne-voltage yehla ohlelweni lonkana).Njengoba isikali sohlelo sikhula, lo mphumela ohlangene wokuvuza kwamanje kanye nokwehla kwamandla kagesi nawo uzokwanda, ngaleyo ndlela kulimaze imigomo yokukhiqiza kanye nezezimali yaso sonke isiteshi samandla elanga esithengiswayo.
Ngokuphambene, ukwakheka okusha okwenziwe lula kwamabhasi e-trunk okuchazwe lapha kuthuthukisa ukusebenza kahle kwegridi ye-DC ngokufaka izintambo ezinkulu ze-trunk ezinoxhumo olumbalwa, ngaleyo ndlela kunikeze ukwehla kwamandla kagesi aphansi kulo lonke uhlelo.
Isixhumi sokubhoboza i-gel solar insulation (GS-IPC).Isixhumi sokubhoboza i-solar insulation esifana nejeli (GS-IPC) sixhuma uchungechunge lwamaphaneli e-photovoltaic ebhasini elidluliswayo.Ibhasi le-trunk liyi-conductor enkulu ethwala izinga eliphezulu lamanje (kufika ku-500 kcmil) phakathi kwenethiwekhi ye-DC ene-voltage ephansi kanye ne-inverter yesistimu DC/AC.
I-GS-IPC isebenzisa ubuchwepheshe bokubhoboza be-insulation.I-blade encane yokubhoboza ingangena kumkhono we-insulation kukhebula futhi isungule uxhumano lukagesi ne-conductor ngaphansi kwe-insulation.Ngesikhathi sokufakwa, uhlangothi olulodwa lwesixhumi "luluma" ikhebula elikhulu, kanti olunye uhlangothi yikhebula lokudonsa.Lokhu kuqeda isidingo sokuba ochwepheshe bendawo benze umsebenzi odla isikhathi futhi okhandlayo wokunciphisa noma wokukhumula.Isixhumi senoveli ye-GS-IPC sidinga kuphela isokhethi noma isikrufu somthelela esinesokhethi ene-hexagonal, futhi uxhumano ngalunye lungafakwa phakathi nemizuzu emibili (lokhu kubikwa ngabamukeli bokuqala besistimu ye-CTS yenoveli) .Njengoba kusetshenziswa ikhanda le-shear bolt, ukufakwa kwenziwa lula.Uma i-torque eklanywe ngaphambili itholakele, ikhanda le-shear bolt lizonqunywa, futhi i-blade yesixhumi ingena kungqimba lwe-cable insulation futhi ifinyelele umugqa womqhubi ngesikhathi esifanayo.Zilimaze.Izingxenye ze-GS-IPC zingasetshenziselwa osayizi bekhebula ukusuka ku-#10 AWG ukuya ku-500 Kcmil.
Ngesikhathi esifanayo, ukuze kuvikelwe lokhu kuxhumana emisebeni ye-UV nezimo zezulu, uxhumano lwe-GS-IPC luhlanganisa nesinye isici esibalulekile sokuklama-izindlu zebhokisi lepulasitiki elivikelayo, elifakwe ekuxhumekeni kwe-trunk/ibhasi ngayinye.Ngemva kokuba isixhumi sifakwe kahle, uchwepheshe wensimu uzobeka futhi avale isivalo nge-TE's Raychem Powergel sealant.Le sealant izokhipha wonke umswakama ekuxhumekeni ngesikhathi sokufakwa futhi isuse ukungena komswakama wesikhathi esizayo phakathi nokuphila kokuxhuma.Igobolondo lebhokisi lejeli lihlinzeka ngokuvikeleka okuphelele kwemvelo kanye nokuncipha komlilo ngokunciphisa ukuvuza kwamanje, ukumelana nemisebe ye-ultraviolet nokukhanya kwelanga.
Sekukonke, amamojula e-GS-IPC asetshenziswa ohlelweni lwe-TE Solar CTS ahlangabezana nezidingo eziqinile ze-UL zezinhlelo ze-photovoltaic.Isixhumi se-GS-IPC sihlolwe ngempumelelo ngokuvumelana ne-UL 486A-486B, CSA C22.2 No. 65-03 kanye nokuhlolwa okusebenzayo kwe-UL6703 esohlwini lwenombolo yefayela le-Underwriters Laboratories Inc. E13288.
I-solar fuse bundle (SFH).I-SFH iwuhlelo lokuhlanganisa oluhlanganisa ama-fuse anesilinganiso esiphezulu esimiswe ngokweqile emgqeni, ompompi, iziswebhu nezixhumi zocingo, ezingahle zilungiswe ukuze zinikeze isisombululo sezintambo zamahhanisi esenziwe ngaphambili esithobelana ne-UL9703.Kuhlelo lwepulazi lelanga elivamile, i-fuse ayikho kumahhanisi ocingo.Esikhundleni salokho, zivame ukutholakala ebhokisini ngalinye lesihlanganisi.Kusetshenziswa le ndlela entsha ye-SFH, i-fuse ishumekwe kumahhanisi ezintambo.Lokhu kunikeza izinzuzo eziningi-kuhlanganisa amayunithi ezinhlamvu amaningi, kunciphisa isamba senani lamabhokisi esihlanganisi adingekayo, kunciphisa izindleko zempahla nezabasebenzi, kwenza ukufakwa kube lula, futhi kukhuphule ukuqhubeka okuhlobene nokusebenza kwesistimu yesikhathi eside, ukugcinwa, nokulondoloza ukuxazulula izinkinga.
Ibhokisi lokunqamula edluliselwe.Ibhokisi lokunqamula i-trunk elisetshenziswe ohlelweni lwe-TE Solar CTS linikeza ukunqanyulwa komthwalo, ukuvikelwa kokuhlinzwa kanye nemisebenzi yokushintsha engalungile, engavikela isistimu ekukhuphukeni ngaphambi kokuba i-inverter ixhumeke, futhi inikeze opharetha ukuxhumana okwengeziwe njengoba kudingeka Futhi inqamule ukuguquguquka kwesistimu. ..Indawo yazo ibalulekile ukuze kuncishiswe ukuxhunywa kwamakhebula (futhi akuthinti ukwehla kwamandla kagesi ohlelweni).
Lawa mabhokisi okuzihlukanisa enziwe nge-fiberglass noma insimbi, anokuhlinzwa nokusebenza okujwayelekile okuphansi, futhi angahlinzeka ngokuphuka komthwalo kufika ku-400A.Basebenzisa izixhumi ze-shear bolt ukuze bafake ngokushesha futhi kalula futhi bahlangabezane nezimfuneko ze-UL zokuhamba ngebhayisikili elishisayo, umswakama kanye nokuhamba ngamabhayisikili kagesi.
Lawa mabhokisi e-trunk anqamula asebenzisa iswishi yokunqamula umthwalo, esiphenduke iswishi engu-1500V ukusuka ekuqaleni.Ngokuphambene, ezinye izixazululo emakethe ngokuvamile zisebenzisa inkinobho yokuhlukanisa eyakhiwe kusuka ku-chassis engu-1000-V, ethuthukisiwe ukuze ibambe i-1500V.Lokhu kungaholela ekukhiqizeni ukushisa okuphezulu ebhokisini lokuhlukanisa.
Ukuze kwandiswe ukwethembeka, lawa mabhokisi anqamula ukudluliselwa asebenzisa amaswishi okunqamula umthwalo omkhulu kanye nezivalo ezinkulu (30″ x 24″ x 10″) ukuze kuthuthukiswe ukunqanyulwa kokushisa.Ngokunjalo, lawa mabhokisi anqamula angakwazi ukumumatha amakhudlwana Irediyasi yokugoba isetshenziselwa izintambo ezinosayizi ukusuka ku-500 AWG ukuya ku-1250 kcmil.
Phequlula amajenali amanje nafakwe kungobo yomlando we-Solar World ngendlela esebenziseka kalula, nekhwalithi ephezulu.Beka uphawu lokubekisa, yabelana futhi uhlanganyele nomagazini abaphambili bokwakhiwa kwelanga manje.
Inqubomgomo yelanga iyahlukahluka kuye kwesinye nesifunda.Chofoza ukuze ubuke isifinyezo sethu sanyanga zonke somthetho wakamuva nocwaningo ezweni lonke.
