Ndisakhumbula ixesha lokuqala endavula ngalo i- Ibhokisi yokudibanisa yeDC eArizona; ivumba elitshileyo landixelela ukuba sitsibe icala lasekunene umkhuseli wokuxhathisa.

Isikhuseli sokushushuluza sijongeka njengesitena esincinci esingwevu esineetheminali zesinyithi, ifestile yesalathisi ebomvu okanye eluhlaza, kunye nelebheli eprintiweyo ebonisa i-voltage, i-current, kunye nophawu lwe-CENdithathe ifoto ye-LKX-PV40 yethu kwaye loo mfanekiso mnye ngoku undigcinela ii-imeyile ezingamashumi amabini kuyo yonke ifowuni yokuthengisa.

Ukuba uthenga izinto zelanga rhoqo ngekota, skrola; amacandelo alandelayo abonisa isizathu sokuba imilo kunye neenkcukacha zigqibe ekubeni indawo yakho ifumana okanye itshisa imali.

I-LKX-PV40: Ukusebenza Okuphezulu Umkhuseli we-DC Surge ngenxa Iinkqubo zelanga?

Ndivavanye iimpawu ezintandathu kwilebhu yethu yaseWenzhou, kwaye yi-LKX-PV40 kuphela egcine i-voltage yokubamba ingaphantsi kwe-1 kV emva kokudubula kathathu kwe-40 kA.

I-LKX-PV40 sisikhuseli se-DC surge esikwaziyo ukuxhuzulwa esine-800 V, 20 kA, 40 kA max, 3.6 kV clamping, kwaye ingena kwi-35 mm DIN rail eqhelekileyo ngaphakathi kwiibhokisi ze-solar combiner.Ndiyigcina kwizindlu ezingwevu okanye ezimnyama kwaye ndiyithumela kwisikhululo sethu esingama-2,000 m² kwiintsuku ezisixhenxe.

Abathengi bahlala bendibuza ukuba kutheni sisebenzisa ityhubhu yegesi kunye ne-MOV hybrid. Impendulo ilula: ityhubhu yegesi ithatha intsimbi yokuqala, i-MOV igqiba umsebenzi, kwaye imodyuli iyasinda kwiifoto ezininzi. Loo mxube unciphisa uhambo lokutshintsha ngesiqingatha kwiindawo zombane apho iikhreyini zibiza ngaphezulu kunesixhobo ngokwaso.

Iindawo eziphambili onokuzibona ngaphandle

Sibumba izindlu ezingaphakathi endlwini ukuze sikwazi ukongeza ilogo yakho okanye sitshintshe umbala ngaphandle kwesixhobo esitsha. Kunyaka ophelileyo i-EPC yaseJamani yayifuna izindlu eziorenji ezifanelana nophawu lwayo; sazisa ii-3,000 pcs kwiintsuku ezilishumi elinesihlanu.

Ibali lombane emva kwebhokisi encinci

Ndiqhuba ezi mvavanyo kuzo zonke iibhetshi. Sigcina ingxelo yovavanyo ebhokisini ukuze iqela lakho le-QC likwazi ukuskena ikhowudi ye-QR lize libone i-pdf yokuqala. Elo nyathelo lincinci lisusa ixhala "lobuxoki lwe-CE" abathengi abaninzi abanalo xa bethenga bevela eTshayina.

Kutheni ii-EPC zikhetha i-LKX-PV40 kwiiprojekthi ze-PV ze-Utility-Scale?

Ndilahlekelwe yitender yasePoland nge-0.02 $/W kuba umphikisi wam weqa izixhobo zokushushumbisa; emva kweenyanga ezintandathu i-EPC efanayo yathenga iiyunithi ezingama-5,000 ze-LKX-PV40 emva kokuba isivuthuvuthu sombane sibulale ii-inverters ezimbini.

Ii-EPC zikhetha i-LKX-PV40 kuba ithunyelwa kwisitokhwe, inika umbane olinganiswe yi-20 kA ohambelana ne-inverter max back-feed eninzi, kwaye imodyuli enokutsalwa ivumela abasebenzi ukuba batshintshe iindawo ngaphantsi komzuzu omnye ngaphandle kokufaka iintambo kwakhona.Ndixhasa iyunithi nganye ngewaranti yeminyaka emihlanu kunye nesithembiso sokutshintsha iiyure ezingama-24 esivela kwiziko lethu lezinto ezingasetyenziswayo laseHamburg.

Iindawo ezinkulu zijongene neentshaba ezimbini: umbane kunye nexesha lokungasebenzi. Iyure enye yokukhupha u-zero kwindawo ye-100 MW itshisa malunga ne-25,000 €. I-LKX-PV40 igcina ixesha lokungasebenzi liphantsi ngeendlela ezintathu: okokuqala, ukususwa kobushushu kuyahamba ngaphambi kokuba indlu inyibilike, ukuze impazamo ingasasazeki; okwesibini, imodyuli iphuma njengesitena seLego, ngoko ke iqela le-O&M lifuna i-screwdriver kuphela; okwesithathu, sibeka inombolo yenxalenye nge-laser kwisiseko nakwi-cartridge, ukuze ungaze udibanise iibhetshi ezindala nezintsha.

Izibalo zexabiso lobunini ezithandwa zii-CFO

Ndibonise le theyibhile kuJeff Weaver, umphathi wezinto ezithengiswayo e-US, ngexesha lomnxeba we-Zoom. Uphendule ngomgca omnye wathi: “Thumela i-2,000 pcs CIF Houston.” Izibalo zithetha lukhulu kunayo nayiphi na incwadana.

Iinkcukacha zobuchwephesha ezibalulekileyo kumaqela okuthenga ngelanga?

Ndakha ndabona indawo ene-30 MW e-Itali ingaphumeleli ukuhlolwa kuba ilebheli ye-SPD yayinoluhlu lwe-600 V kuphela; umhloli wayefuna i-1,000 Vdc kwaye sayilungisa nge-LKX-PV40 kwiintsuku ezimbini.

Abathengi belanga bakhathalele i-Ucpv 800 Vdc ukugubungela iintambo ze-V eziyi-1,500 kwiidigri ezingama-20 ngaphantsi, kwi-20 kA ukuze isixhobo singaphazamisi xa siphezulu, kunye ne-plug-in foot-print ehambelana neMidNite Solar kunye ne-ABB bases ukuze bakwazi ukuxuba iimpawu kwibhokisi enye.Ndiprinta le migca mithathu kwiphepha elingaphambili lesicatshulwa ngasinye.

Amaqela okuthenga ahlala kwi-Excel. Ahlela iikholamu ngokwexabiso, i-MOQ, kunye nexesha lokuqalisa. Ndongeza iikholamu ezimbini ezifihlakeleyo: “eziqinisekileyo ukuba ziyinyani okanye azinyanisekanga” kunye “nomgama wefektri ukuya echwebeni.” IWenzhou iyure enye ukusuka echwebeni laseNingbo, ngoko ke iikhonteyina zethu zilayisha ngoMvulo kwaye zihamba ngoLwesibini. Loo ndlela imfutshane inciphisa imithwalo nge-4% xa ithelekiswa neefektri zangaphakathi. Isihloko sesatifikethi sinzima; abathengisi abaninzi babonisa iphepha le-CE lika-2016 eliphelelwe lixesha. Sihlaziya ingxelo yethu ye-TUV minyaka le kwaye siyilayishe kwiseva yethu ukuze abathengi bakwazi ukujonga umhla kwi-intanethi.

Oko kuthethwa zizifinyezo ngamagama alula

- I-Ucpv: i-voltage ephezulu ye-dc onokuyixhuma ngonaphakade ngaphandle kokubamba umlilo yi-SPD

- Ngaphakathi: la mandla angoku i-SPD inokuginya amaxesha angama-20 kwaye isasebenza

- Imax: umbane omkhulu we-shot one i-SPD enokuyithatha ngaphambi kokuba ife

- Phezulu: i-voltage esangena kwi-inverter yakho; esezantsi ingcono

Ukuba i-Up yi-3.6 kV kwaye i-inverter yakho inokuthatha i-4 kV, une-0.4 kV yokhuseleko. Ngeentsasa ezibandayo i-voltage ye-open-circuit yephaneli iyanyuka, ukuze i-margin inciphe. Ndisoloko ndixelela abathengi ukuba bakhethe i-SPD ene-Up engaphantsi kwama-80% we-inverter surge rating. Loo mthetho usindise iprojekthi ye-50 MW eTexas ebusika obudlulileyo.

Ukusuka kwiSpec Sheet ukuya kwiSayithi: Ungayifakela njani i-LKX-PV40 kwiibhokisi zeCombiner?

Ndafika eChile ndinebhegi yomqolo kunye ne-torque driver kuphela; ngexesha lesidlo sasemini mna neqela sasifake iiyunithi ezili-120 ze-LKX-PV40 kwaye isityalo saphumelela uvavanyo lwe-HV ngaloo mini.

Faka i-LKX-PV40 ngokunqamla isiseko kwi-35 mm DIN rail, uqinise iingcingo ze-PV zibe yi-1.5 Nm kwii-ports ze-4 mm², cofa imodyuli ude uve ukuklikha, kwaye uqondise i-earth wire kwi-box bus-bar ukuze indlela ye-fault ibe mfutshane kune-10 cm.Ndithumela incwadi yesikhokelo yekhathuni enephepha elinye kwibhokisi nganye ukuze namaqela abasebenzi basemini ayenze kakuhle loo nto.

Abafaki abaninzi bayalibala ukujonga i-polarity. Izihlanganisi ze-DC ziyafana, kodwa isiseko se-LKX-PV40 sinobumba "+" kunye no-"–" obunjwe ngoonobumba abangqindilili. I-polarity ebuyela umva ayibulali i-SPD, kodwa ifestile yesalathisi inokubonisa ubomvu nokuba inxalenye ilungile. Loo flegi yobuxoki ichitha ixesha le-O&M. Songeza isitika esityheli esithi "Jonga i-polarity ngaphambi kokuba ungene kwi-clip-in." Ukususela oko songeze isitika, izinga lethu le-RMA lehle ukusuka kwi-1.2% ukuya kwi-0.3%.

Uluhlu lwamanyathelo onokulunamathelisa ngaphakathi kwesiciko

1. Cima iswitshi yeDC
2. I-voltage yesekethe evulekileyo yovavanyo lwentambo
3. Intambo yokubopha 8 mm
4. Faka i-port kunye ne-torque kwi-1.5 Nm
5. Imodyuli yesikliphu
6. Vala isiciko
7. Layita
8. Jonga ukuba ifestile iluhlaza

Ndigcina ividiyo emfutshane yala manyathelo asibhozo kwifowuni yam; Ndiyayithumela kwi-site foremen xa becela ifayile yoqeqesho. Ikliphu yonke yimizuzwana engama-38, ngoko ke ikwasebenza nakwiinethiwekhi ze-3G ezicothayo kwiindawo zasemaphandleni zaseIndiya.

Amaxabiso amaninzi kunye neenketho ze-OEM zabaSasazi kunye nabaHlanganisi beNkqubo?

Umsasazi waseJordan undithumelele i-imeyile ngentsimbi yesi-2 kusasa ecela ii-pcs eziyi-8,000 kunye nelogo yakhe kunye nelebheli yesiArabhu; sithumele ngeentsuku ezili-18 kwaye usaphinda aodole rhoqo ngekota.

Sinikezela ngamaxabiso amakhulu ngamaqhekeza angama-500, angama-2,000, kunye nama-10,000, siprinta ilogo yakho kunye nenombolo yenxalenye kwikhabhathi, kwaye singapakisha iiyunithi ezilishumi elinesibini kwikhathoni encinci ukuze ulayishe ii-pcs ezingama-9,600 kwi-HQ engama-40 endaweni ye-7,200 eqhelekileyo.
