Ukuba ububukele indlela yelanga yaseIndiya, amanani ayamangalisa. Eli lizwe longeze amandla elanga angaphezu kwama-50 GW kwiminyaka emibini edlulileyo kuphela, kwaye isantya asibonisi zimpawu zokucotha. Emva kwayo yonke i-array esebenzayo kukho uthungelwano lwezinto zonxibelelwano abantu abaninzi abangaziboniyo - kwaye phakathi kwezona zibalulekileyo, kodwa zihlala zichazwa gwenxa, zezi Iibhloko zesiphelo se-1500V DC ndihleli ngaphakathi kwiibhokisi ze-combiner. Ndichithe iminyaka elishumi elinesihlanu ndisebenza kunye nabavelisi beebhokisi ze-combiner, ii-EPC, kunye nabaphuhlisi beeprojekthi kulo lonke elaseIndiya, kwaye ndingakuxelela ukuba ukukhetha iibhloko zesiphelo sendlela yenye yezo nkcukacha ezimisela ngokuzolileyo ukuba isityalo sisebenza ngokuthembekileyo iminyaka engama-25 okanye sibangela iintloko ezibuhlungu ezingapheliyo ukusuka kunyaka wesithathu ukuya phambili.

Kule posi, ndiza kukubonisa kanye into efunwa ngabakhi beebhokisi ze-combiner xa bechaza iibhloko zesiphelo ze-1500V DC zeefama zelanga zaseIndiya. Ndiza kukubonisa uthelekiso lwemveliso ecaleni, ndikubonise indlela yokukhetha esebenzayo, kwaye ndikunike iingcebiso zesicelo onokuthi uzisebenzise namhlanje. Nokuba ungunjineli ovavanya iinxalenye zebhokisi ze-combiner okanye umphathi weprojekthi ofuna ukuqonda ukuba umthengisi wakho ongaphantsi uchaza ntoni na, esi sikhokelo sesakho.

Utshintsho lweVolthi yeFama yeSolar yaseIndiya ukuya kwi-1500V DC Architecture

Masiqale ngesizathu esisisiseko sokuba iinkqubo ze-1500V zibe ngumgangatho kwiifama zelanga zaseIndiya: ukusebenza kakuhle kweendleko ngokusebenzisa ulwandiso lobude bentamboXa unyusa i-voltage yenkqubo ukusuka kwi-1000V ukuya kwi-1500V, ungaqhagamshela iimodyuli ezingaphezulu ngentambo nganye, oko kuthetha ukuba zimbalwa iibhokisi zokudibanisa, iintambo ze-DC ezimbalwa, kunye neendawo zokuphelisa ezimbalwa. ILebhu yeSizwe yaMandla aHlaziyiweyo (NREL), ukunyuka kwe-voltage ukuya kwi-1500V kuye kwanikezela ngokunciphisa kwe-3–7% kwiindleko ze-BoS (iBalance of System) kwiiprojekthi zesikali seenkonzo eIndiya nakwihlabathi liphela.

Kubaphuhlisi baseIndiya abasebenza kumazwe afana neRajasthan, iGujarat, kunye neTelangana apho iindleko zomhlaba zinyuka kwaye uxinzelelo lwegridi luyinyani, yonke ipesenti yokonga kweBoS ibalulekile. Yiyo loo nto sibona iiprojekthi ezinkulu ezivela kwi-NTPC, i-SECI, kunye nabaphuhlisi babucala besamkela ngakumbi uyilo lwe-1500V DC. Kodwa i-voltage ephezulu ikwathetha ukuba izinto kufuneka zisebenze phantsi koxinzelelo olukhulu lombane - kwaye kulapho kanye ibhloko yesiphelo esithobekileyo iba yinto ebaluleke kakhulu.

Ukutshintshela kwi-1500V DC akuyonto nje yokukhetha ubunjineli; yinto ebalulekileyo kwezoqoqosho eqhutywa ziinjongo zamandla avuselelekayo zaseIndiya kunye nesidingo sokuhambisa amandla elanga ngexabiso eliphantsi. Xa uxinzelelo lwamaxabiso e-L1 lunyanzela abaphuhlisi ukuba baphucule yonke inkqubo engaphantsi, ukukhetha ibhloko yesiphelo esifanelekileyo akuyonto ilula - yindlela yokuphila yokusebenza kwesityalo ixesha elide.

Yintoni iBloko yesiphelo se-1500V DC kwaye kutheni ibalulekile kwibhokisi ye-Combiner?

Ibhloko yesiphelo yinxalenye yombane enika indlela elula yokudibanisa iingcingo. Kwibhokisi yokudibanisa yelanga, iintambo ezininzi zentambo ezivela kwiimodyuli zePV nganye ziyadibana kwiibhloko zesiphelo ngaphambi kokuba zidlulisele umbane kwisikhululo se-inverter esiphakathi. Kwi-1500V DC, iingozi ziphezulu kakhulu kunakwizinga le-1000V.

Imingeni ephambili kwi-1500V DC ibandakanya:

• Umngcipheko ophezulu wempazamo ye-arc: Ii-arc ze-DC kunzima ukuzicima kunee-arc ze-AC kuba i-DC ayinayo i-zero-crossing yendalo. Kufuneka kwenziwe i-terminal block ukuze ibambe kwaye icinezele ii-arc ze-DC.
• Iimfuno zokwanda kokuqhekeka kunye nokususwa kwenkunkuma: I-voltage ephezulu ifuna umgama omkhulu phakathi kweendawo eziqhuba umbane ukuze kuthintelwe ukulandelelwa kunye nokutsha kwe-flashover, ingakumbi kwiindawo ezinothuli nezifumileyo zaseIndiya.
• Uxinzelelo lokujikeleza kobushushu: Izityalo zelanga zaseIndiya zifumana utshintsho lobushushu ukusuka kwi-0°C kusasa ebusika ukuya kwi-50°C emva kwemini yasehlotyeni. Iibhloko zesiphelo kufuneka ziphile amawaka emijikelo yobushushu ngaphandle kokukhulula okanye ukwehlisa ukumelana noqhagamshelwano.
• Ukuvezwa kwe-UV kunye nokusingqongileyo: Iibhokisi zokudibanisa, nangona zikhusela, zihlala zifakelwa kwiindawo ezivulekileyo apho i-UV ichaphazeleka ngqo kumphezulu ovalekileyo.

Xa sivavanya iibhloko zesiphelo sendlela yokusetyenziswa kweebhokisi ze-combiner, ndisoloko ndigxininisa ukuba umlinganiselo we-voltage yecandelo kufuneka udlule i-voltage yenkqubo ngomda wokhuseleko owaneleyo - ngesiqhelo yi-20–30% ngaphezulu kwe-voltage ephezulu yokusebenza. Oku akuyongxaki yethiyori; yinto esebenzayo endiyibonileyo ethintela ukusilela kwangaphambi kwexesha kwicandelo.

Zimisele ukufumana izatifikethi zovavanyo zomntu wesithathu — ngcono ezivela kwiilabhoratri ezivunyiweyo — eziqinisekisa i-voltage yokwenyani evavanyiweyo, kungekuphela nje i-voltage elinganisiweyo. Imibutho efana nale I-TÜV kunye neenkampani zovavanyo ezisebenzisana ne-IEC zibonelela ngezi zatifikethi, kwaye sihlala sizithelekisa nezinye Umgangatho we-IEC 61835 kwizixhobo zokukhusela umbane ze-PV DC.

Inyathelo lesi-2 — Ukuhambelana komqhubi

Jonga uhlobo oluchanekileyo lwekhontraktha kunye nobungakanani obamkelekileyo kwibhloko yesiphelo. Iiprojekthi zelanga zaseIndiya zisebenzisa kakhulu iintambo ze-aluminium conductor armored (ACA) okanye iikhontraktha eziguquguqukayo zobhedu kwiintambo zentambo. Amava ethu abonisa ukuba iikhontraktha ze-aluminium kuluhlu lwe-4–16 mm² zifuna iibhloko zesiphelo ezinoyilo olufanelekileyo lwekheyiji oluthintela ukuhamba komoya obandayo kwaye lugcine ukumelana okuzinzileyo koqhagamshelwano ngokuhamba kwexesha. Ukuba iprojekthi yakho isebenzisa i-aluminium, qiniseka ukuba ibhloko yesiphelo ilinganiswe kwiintambo ze-Al/Cu.

Inyathelo lesi-3 — Ukusebenza kokusingqongileyo

Kwiibhokisi zokudibanisa ezisetyenziswa kwiimeko zaseIndiya, ndicebisa ubuncinci Uvavanyo lokulibaziseka kwelangatye lwe-UL94 V-0 kunye nobubanzi bobushushu bokusebenza obuphakathi kwe-−40°C ukuya kwi-+105°C. Iindawo zaseRajasthan zinokubona ubushushu bomphezulu obuvalekileyo beebhokisi zokudibanisa ezidlula i-70°C ehlotyeni eliphezulu — izinto kufuneka ziphile kwezi meko ngaphandle kokuguquka okanye ukuwohloka koqhagamshelwano. Khangela ii-polyamide (PA) okanye izindlu ze-thermoplastic ezenziwe ngobunjineli ezine-UV stabilization eqinisekisiweyo ukuba ibhokisi yokudibanisa ayivalwanga ngokupheleleyo kwindawo yokukhusela elawulwa bubushushu.

Inyathelo lesi-4 — Isiqinisekiso kunye neMigangatho

Kwiiprojekthi zaseIndiya eziqhagamshelwe kwigridi yesizwe, iibhloko zakho zesiphelo kufuneka zibe neziqinisekiso ezihambelana neMigangatho yaseIndiya (IS) efanelekileyo kunye nezilinganiso zamazwe ngamazwe. Iziqinisekiso eziphambili zokuqinisekisa:

• Ukuthobela iRoHS kunye neREACH kukhuseleko lokusingqongileyo

Inyathelo lesi-5 — Inkxaso yoMvelisi kunye nokuLandelelwa

Kulapho amaqela amaninzi okuthenga athatha khona amanyathelo, kwaye ndibone iziphumo. Khetha umenzi onokubonelela ukulandeleka kwinqanaba lebhetshi, izatifikethi zezinto eziphathekayo, kunye nenkxaso yobugcisa eIndiya. Xa ibhokisi ye-combiner ingasebenzi kakuhle kwindawo ohlala kuyo kwaye ufuna uhlalutyo lwesizathu, ufuna umthengisi onokukubonisa iirekhodi zebhetshi yemveliso yakhe. KwaNingbo J Guang, sigcina ukulandeleka okupheleleyo kuyo yonke imveliso, kwaye ndikholelwa ukuba oku akunakuxoxiswana ngako nakweyiphi na i-combiner box builder enzulu.

Iingcebiso zesicelo: Ukusebenzisa iiBhloko zesiphelo se-1500V DC kwiiprojekthi zelanga zaseIndiya

Ngoku mandichaze ngokucacileyo ngeemeko zokusetyenziswa kwezixhobo zelanga endizifumeneyo kwiifama zaseIndiya. Ezi ziingcebiso ezivavanyiweyo kwintsimi, hayi ithiyori yeencwadi.

Imeko 1: Isityalo Esikhulu Esisetyenziswa Ngamandla (Multi-MW, Rajasthan okanye Gujarat)

Kwizityalo ezinkulu ezikwiindawo ezinobushushu obuphezulu, ezinothuli oluninzi, ndiyacebisa Iibhloko zesiphelo sekheji yentwasahlobo ezifakwe kwi-DIN rail ezineenguqulelo zokucima i-arc yokuphelisa ukufakwa kwentambo, edibene ne-snake-switch enzima okanye ii-bus bar terminals ze-DC output eziphambili. Isizathu esiphambili kukuthembeka phantsi komjikelo oshushu kakhulu. ERajasthan, iibhokisi ze-combiner zinokufumana ubushushu obungama-40°C imihla ngemihla. Ii-terminals ze-spring cage zigcina uxinzelelo oluhambelanayo nokuba ubushushu buyanda kangakanani na, ngelixa ii-terminals zohlobo lwe-screw zinokusebenza ngokukhululekileyo kwimijikelo yokuqala engama-500 yobushushu.

Ukongeza, chaza iibhloko zesiphelo ezinezitebhisi ezimbini apho isithuba sebhokisi yokudibanisa silinganiselwe — zinika uxinano olufanayo kwisiqingatha sobubanzi. Ungakhangela i-intanethi yethu epheleleyo ikhathalogu yemveliso ukuze sibone uluhlu lweendlela zokumisela i-DIN rail terminal esizibonelelayo kwizicelo zelanga.

Imeko yesi-2: Uphahla okanye iFayile yoRhwebo neyeMizi-mveliso (eTelangana okanye eMaharashtra)

Kwiiprojekthi eziphakathi apho iibhokisi zokudibanisa zinokufakelwa kufutshane nezakhiwo okanye kwiindawo ezinombala ongaphelelanga, iibhloko zesiphelo sokutyhala ezisebenza ngokudibeneyo kunye nokusebenza kokuqhawula zibonelela ngokulinganisela okugqwesileyo kwesantya sokufakela kunye nokhuseleko. Ezi zivumela abasebenzi bokulungisa ukuba bahlukanise iisekethe zomtya ngamnye ngaphandle kokuphazamisa uluhlu lonke. Umjikelo wokufakela okhawulezayo ukwabalulekile nakwiiprojekthi zorhwebo apho amaxesha e-EPC aqinileyo.

Imeko 3: Iindawo ezikunxweme okanye ezifumileyo kakhulu (eTamil Nadu, eKerala)

Ukuba iprojekthi yakho ikwindawo eselunxwemeni, ukumelana nokugqwala kuba yikhrayitheriya ephambili yokukhetha. Ndicebisa ukuba ukhethe iibhloko zesiphelo ezine izinto zokufaka ubhedu ezifakwe kwi-nickel kunye neendawo zokuhlala ze-thermoplastic ezikumgangatho ophezulu ezilinganiswe ngokuchatshazelwa yityuwa ngokutsho kwe-IEC 60068-2-52. Iibhloko zesiphelo eziqhelekileyo ezingenalo ukhuselo lokugqwala ziya kubonisa ukuwohloka kwiminyaka emi-3-5 kwiindawo zaseIndiya ezikunxweme. Sifunde oku ngendlela enzima ngeprojekthi yokuqala eTamil Nadu, kwaye yingakho ngoku sihlala sibuza malunga nokusondela konxweme lwendawo ngexesha leengxoxo zeenkcukacha.

Imeko 4: Iiprojekthi zokuvuselela okanye zokubuyisela amandla

Iifama zokuqala zelanga zaseIndiya ukususela ngo-2012–2016 ziya ziphinda ziphuculwe ukuze ziphuculwe ukusuka kwi-1000V ukuya kwi-1500V. Oku kuveza umngeni othile: iibhokisi ze-combiner ezikhoyo zisenokuba azizange zenzelwe izinto ze-1500V. Kule meko, sihlala sicebisa ukutshintshwa kwebhokisi ye-combiner epheleleyo endaweni yokuzama ukuphuculwa okungaphelelanga, kuba i-enclosure geometry, imigama ye-creepage, kunye noqwalaselo lwebha yebhasi zonke kufuneka zihlolwe kwakhona ukuze zifumane i-voltage ephezulu. umgca wemveliso yebhloko yesiphelo ibandakanya uyilo oluncinci olunokungena kwiindawo zokufakela izinto ezintsha, kodwa ndisoloko ndicebisa ukuba ujonge ukufaneleka komzimba ngaphambi kokuba uthenge.

Kwenzeka ntoni xa ucacisa i-Terminal Block engalunganga?

Ndifuna ukuthetha ngqo ngale nto kuba ndizibonile iziphumo zayo. Ezona ndlela zixhaphakileyo zokusilela endizibonileyo kwiibhloko zesiphelo ezingachazwanga kakuhle kwizityalo zelanga zaseIndiya ziquka:

• Ukunyuka kokumelana noqhagamshelwano: Uqhagamshelo olukhululekileyo lubangela ubushushu obukwindawo ethile, nto leyo ekhawulezisa i-oxidation kwaye yonyusa ukumelana — umjikelo ombi okhokelela kwiindawo ezishushu ezibonwayo ngemifanekiso yobushushu.
• Ukulandelela i-Arc: Kwiibhokisi zokudibanisa ezinothuli nezifumileyo, ungcoliseko lomphezulu ludala indlela eqhuba umbane ebangela ukungaphumeleli kokulandelela kumphezulu webhloko yesiphelo. Oku kuqheleke kakhulu kwi-1500V kunakwi-1000V kuba uxinzelelo lwentsimi yombane luphezulu.
• Ukutsalwa kwentambo: Iibhloko zesiphelo ezingabambi kakuhle umqhubi zivumela ukuba iintambo zikhutshwe ngexesha lokulungiswa okanye ngenxa yoxinzelelo lokwandiswa kobushushu. Oku kudala imeko yesekethe evulekileyo ekunzima ukuyifumanisa ngokukhawuleza.
• Umlilo obiyelweyo: Nangona kunqabile, elona tyala linzima endiliphandileyo libandakanya ibhloko yesiphelo eyayingenako ukugcina i-DC arc, nto leyo eyabangela umlilo webhokisi ye-combiner owatshabalalisa indawo ebiyelweyo waza wonakala neentambo zentambo ezikufutshane. Oku kungathintelwa ngokupheleleyo ngeenkcukacha ezifanelekileyo.

Xa ndichaza ezi ndlela zokusilela kubaphuhlisi beprojekthi, impendulo idla ngokuba: "Besingazi ukuba iibhloko zesiphelo zibaluleke kangaka." Oko kuyaqondakala - kwiindlela zecandelo, abantu bagxila kwii-inverters, iimodyuli, kunye nee-trackers. Kodwa kumava am, izinto ezimisela ukuba isityalo siyawufikelela na umthamo waso ojoliswe kuwo unyaka nonyaka zihlala ziindawo zokunxibelelana ezingaqhelekanga: iibhloko zesiphelo, iifusi, kunye neeswitshi zokuqhawula.

Ityala lezoqoqosho lokukhetha okulungileyo: Kutheni kuhlawulela abaphuhlisi

Mandicacise ingxoxo yezoqoqosho kuba le yinto edla ngokukholisa abaphathi beeprojekthi kunye namaqela ezezimali. Ibhloko yesiphelo se-1500V DC esemgangathweni ophezulu ingabiza i-$2–5 ngepali enye ngaphezu kwebhajethi. Kwisityalo selanga esiqhelekileyo se-150 MW esineebhokisi zokudibanisa ezingama-500, nganye ineepali zesiphelo se-20–40, umahluko weendleko ezinyukayo umalunga ne-$20,000–$100,000 — into encinci xa ithelekiswa neendleko zeprojekthi ezipheleleyo ze-$100–150 yezigidi.

Ngoku qwalasela iindleko zesiganeko esinye sokusilela kwebhokisi ye-combiner: utyelelo lwesiza ($3,000–$8,000), ukulahleka kokuveliswa kwi-grid average tariffs ye-₹2.5–4 nge-kWh, isohlwayo esinokubakho esivela kwi-DISCOM ngenxa yokunqongophala kokufumaneka, kunye nomngcipheko wodumo kubabolekisi kunye nabatyali-mali. Umcimbi omnye othintelwe ukusilela kwebhokisi ye-combiner uhlawula ngaphezu kokuphucula ubomi bonke bokusebenza kwesityalo. Xa ujonga ngaloo ndlela, ndikholelwa ukuba ukhetho oluchanekileyo kuphela kukuchaza ngokuchanekileyo ukususela ngomhla wokuqala.

I Inkampani yeWestern Electric Coil kunye neCable (WECC) ipapashe izikhokelo malunga nokuthembeka kwenkqubo ye-PV eziqinisekisa le mbono yeendleko zolondolozo - iiprojekthi ezityala imali kwizixhobo zeBoS ezisemgangathweni zihlala ziphumelela kakhulu kwiimilinganiselo zokufumaneka, ezondla ngokuthe ngqo kwimodeli yengeniso yesityalo.

Indlela Yokusebenza Nomakhi Wakho Webhokisi Yokudibanisa: Isikhokelo Esisebenzayo

Ngokusekelwe kumava am okuxhasa abavelisi beebhokisi zokudibanisa, nantsi into endiyicebisayo xa ukwisigaba sokuchazwa kunye nomthengisi wakho ongaphantsi:

1. Cela i-datasheet ye-terminal block kunye nesatifikethi sovavanyo lomntu wesithathu ngaphambi kokuba ukhuphe i-PO. Qinisekisa ukulinganiswa kwamandla ombane, iziphumo zovavanyo lwe-dielectric, kunye noluhlu lomqhubi.
2. Buza ngenkqubo yokulandelela umkhondo welothi yomenzi. Ukuba abakwazi ukubonelela ngokulandelelana kwinqanaba lebhetshi, loo nto ithetha ukuba inkqubo yabo yolawulo lomgangatho ayizukulandelwa.
3. Cacisa ngokucacileyo iimeko zokusingqongileyo: ubushushu obuphezulu/ubuncinci, ukufuma, ukuphakama, inqanaba lokuvezwa yi-UV, kunye nokuba indawo ilunxwemeni na. Musa ukuzicingela ezi zinto.
4. Cela isampulu yangaphambi kokuveliswa ukuze uhlolwe ukuba umzimba wakho uphilile na kuyilo lwakho lwebhokisi yokudibanisa, ingakumbi ukuba usebenzisa uyilo olutsha lwe-enclosure okanye imeko yokulungisa izinto.
5. Faka iibhloko zesiphelo kwiprotocol yakho ye-FAT (Factory Acceptance Test). Qinisekisa ukuba i-torque yokuphelisa (kwiintlobo zezikrufu) okanye ubunzulu bokufaka (kwiintlobo zokutyhala) ziyahlangabezana namaxabiso ashicilelweyo ngumvelisi.

Ukuba umakhi webhokisi yakho yokudibanisa usebenzisa iibhloko zesiphelo sebhajethi ukuphumelela ikhontrakthi yokubonelela, umthwalo usemahlombe akho njengomphuhlisi weprojekthi wokubuza imibuzo enzima. Ndibone iiprojekthi ezininzi kakhulu apho iinkcukacha zecandelo leBoS zishiywe ngokupheleleyo kumthengisi ongaphantsi, kodwa oko kwaphumela kwizohlwayo zokufumaneka kunyaka wokuqala wokusebenza.
