Ngisakhumbula isikhathi sokuqala ngivula i- Ibhokisi lokuhlanganisa le-DC e-Arizona; iphunga elishile langitshela ukuthi seqe ngakwesokudla isivikelo sokukhuphuka.

Isivikelo sokukhuphuka sibukeka njengesitini esincane esimpunga esineziphetho zensimbi, ifasitela elibonisa isibonakaliso elibomvu noma eliluhlaza, kanye nelebula eliphrintiwe elibonisa i-voltage, i-current, kanye nophawu lwe-CENgithathe isithombe se-LKX-PV40 yethu futhi leso sithombe esisodwa manje singigcinela ama-imeyili angamashumi amabili kukho konke ukushaya kwentengiso.

Uma uthenga izingxenye zelanga njalo ngekota, skrola; izigaba ezilandelayo zibonisa ukuthi kungani ukuma kanye nemininingwane kunquma ukuthi isayithi lakho lithola noma lishisa imali.

I-LKX-PV40: Ukusebenza Okuphezulu Isivikelo Sokukhuphuka kwe-DC ngoba Izinhlelo Zelanga?

Ngivivinye izinhlobo eziyisithupha elabhorethri yethu yaseWenzhou, futhi yi-LKX-PV40 kuphela egcine i-voltage yokubamba ingaphansi kwe-1 kV ngemuva kokudubula kathathu kwe-40 kA.

I-LKX-PV40 iyisivikelo se-DC surge esixhunywayo esinesilinganiso esingu-800 V, 20 kA, 40 kA max, 3.6 kV clamping, futhi ifanelana nesitimela se-DIN esijwayelekile esingu-35 mm ngaphakathi kwamabhokisi e-solar combiner.Ngiyigcina endlini empunga noma emnyama bese ngiyithumela zingakapheli izinsuku eziyisikhombisa ngisuka esitshalweni sethu esingama-2,000 m².

Abathengi bavame ukungibuza ukuthi kungani sisebenzisa ipayipi likaphethiloli kanye ne-MOV hybrid. Impendulo ilula: ipayipi likaphethiloli lithola ithuba lokuqala, i-MOV iqeda umsebenzi, futhi imodyuli isinda ekushayweni okuningi. Leyo nhlanganisela inciphisa uhambo lokufaka esikhundleni ngesigamu ezindaweni zokusetshenziswa lapho ama-crane ebiza khona ngaphezu kwedivayisi uqobo.

Izingxenye ezibalulekile ongazibona ngaphandle

Sibumba izindlu ngaphakathi endlini ukuze sikwazi ukwengeza ilogo yakho noma sishintshe umbala ngaphandle kwethuluzi elisha. Ngonyaka odlule i-EPC yaseJalimane yayifuna izindlu ezi-orenji ezifanelana nomkhiqizo wayo; saletha ama-pcs angu-3,000 ngezinsuku eziyishumi nanhlanu.

Indaba kagesi ngemuva kwebhokisi elincane

Ngiqhuba lezi zivivinyo kuwo wonke amaqoqo. Sigcina umbiko wokuhlolwa ebhokisini ukuze ithimba lakho le-QC likwazi ukuskena ikhodi ye-QR bese libona i-pdf yokuqala. Leso sinyathelo esincane sisusa ukukhathazeka "kwe-CE mbumbulu" abathengi abaningi abanakho lapho bethenga bevela eShayina.

Kungani ama-EPC ekhetha i-LKX-PV40 kumaphrojekthi e-PV e-Utility-Scale?

Ngilahlekelwe yithenda yasePoland ngo-0.02 $/W ngoba imbangi yami yeqa igiya lokushushuluza; ezinyangeni eziyisithupha kamuva i-EPC efanayo yathenga amayunithi angu-5,000 e-LKX-PV40 ngemuva kokuba isiphepho sombani sibulale ama-inverter amabili.

Ama-EPC akhetha i-LKX-PV40 ngoba ithunyelwa kusuka esitokweni, inikeza ugesi olinganiselwe we-20 kA ohambisana ne-inverter max back-feed eminingi, futhi imodyuli evulekayo ivumela abasebenzi ukuthi bashintshe izingxenye ngaphansi komzuzu owodwa ngaphandle kokuxhuma kabusha izintambo.Ngisekela iyunithi ngayinye ngewaranti yeminyaka emihlanu kanye nesithembiso sokushintsha samahora angu-24 esivela esikhungweni sethu sezingxenye ezisele saseHamburg.

Izindawo ezinkulu zibhekene nezitha ezimbili: umbani nesikhathi sokungasebenzi. Ihora elilodwa lokukhipha okungu-zero endaweni engu-100 MW lishisa cishe ama-€ angu-25,000. I-LKX-PV40 igcina isikhathi sokungasebenzi siphansi ngezindlela ezintathu: okokuqala, ukunqanyulwa kokushisa kuyawa ngaphambi kokuba indlu incibilike, ukuze iphutha lingasabalali; okwesibili, imodyuli iphuma njengesitini seLego, ngakho-ke iqembu le-O&M lidinga i-screwdriver kuphela; okwesithathu, sifaka inombolo yengxenye nge-laser kokubili isisekelo kanye ne-cartridge, ukuze ungalokothi uhlanganise ama-batch amadala namasha.

Izindleko zobunikazi ezithandwa yi-CFOs

Ngibonise leli thebula kuJeff Weaver, umphathi wezokuthengwa kwempahla wase-US, ngesikhathi socingo lwe-Zoom. Uphendule ngomugqa owodwa: “Thumela ama-2,000 pcs CIF Houston.” Izibalo zikhuluma kakhulu kunanoma iyiphi incwajana.

Imininingwane Yobuchwepheshe Ebalulekile Kumaqembu Okuthengwa Kwelanga?

Ngake ngabona indawo enamandla angu-30 MW e-Italy ihluleka ukuhlolwa ngoba ilebula le-SPD lalinophawu lwe-600 V kuphela; umhloli wayefuna i-Vdc eyi-1,000 futhi sayilungisa nge-LKX-PV40 ezinsukwini ezimbili.

Abathengi belanga bakhathalela i-Ucpv 800 Vdc ukumboza izintambo ze-V ezingu-1,500 kuma-degree angamashumi amabili ngaphansi, ku-20 kA ukuze idivayisi ingaphazamisi ekuphakameni okuphezulu, kanye ne-plug-in foot-print ehambisana nezisekelo ze-MidNite Solar kanye ne-ABB ukuze bakwazi ukuxuba izinhlobo ebhokisini elifanayo.Nginyathelisa le migqa emithathu ekhasini lokuqala lanoma iyiphi ingcaphuno.

Amaqembu okuthenga ahlala e-Excel. Ahlela amakholomu ngentengo, i-MOQ, kanye nesikhathi sokulethwa. Ngifaka amakholomu amabili afihliwe: “iqiniso langempela noma lamanga” kanye “nebanga lefektri ukuya echwebeni.” I-Wenzhou ihora elilodwa ukusuka echwebeni laseNingbo, ngakho-ke amakhonteyina ethu alayisha ngoMsombuluko bese ehamba ngoLwesibili. Lowo mzila omfushane unciphisa imithwalo ngo-4% uma kuqhathaniswa namafektri angaphakathi ezweni. Isihloko sesitifiketi sinzima; abahlinzeki abaningi babonisa iphepha le-CE lika-2016 eliphelelwe yisikhathi. Sibuyekeza umbiko wethu we-TUV njalo ngonyaka futhi siwulayishe kuseva yethu ukuze abathengi bakwazi ukuhlola usuku ku-inthanethi.

Okushiwo yizifinyezo ngamazwi alula

- I-Ucpv: i-voltage ephezulu kakhulu ye-dc ongayixhuma unomphela ngaphandle kokubamba umlilo kwe-SPD

- Ku-: amandla amanje i-SPD ingawagwinya izikhathi ezingu-20 futhi isasebenza

- I-Imax: umfutho omkhulu kakhulu we-SPD ongawuthatha ngaphambi kokuba ufe

- Phezulu: i-voltage esangena iye kwi-inverter yakho; ephansi ingcono

Uma i-Up ingu-3.6 kV futhi i-inverter yakho ingathatha i-4 kV, une-margin yokuphepha engu-0.4 kV. Ekuseni okubandayo i-voltage ye-open-circuit yephaneli iyakhuphuka, ngakho-ke i-margin iyancipha. Ngihlala ngitshela abathengi ukuthi bakhethe i-SPD ene-Up ngaphansi kwama-80% wesilinganiso sokwanda kwe-inverter. Lowo mthetho usindise iphrojekthi engu-50 MW eTexas ebusika obudlule.

Kusukela Kushidi Elicacisiwe Kuya Kusayithi: Ungayifaka Kanjani i-LKX-PV40 Kumabhokisi Okuhlanganisa?

Ngafika eChile nginobhaka kanye ne-torque driver kuphela; ngesikhathi sesidlo sasemini mina nabasebenzi base sifake amayunithi angu-120 e-LKX-PV40 futhi isitshalo saphumelela ukuhlolwa kwe-HV ngalolo suku.

Faka i-LKX-PV40 ngokunqamula isisekelo ku-35 mm DIN rail, uqinise izintambo ze-PV zibe yi-1.5 Nm kuma-port angu-4 mm², unqamule imojuli uze uzwe ukuchofoza, bese uhambisa intambo yomhlaba ngebha yebhasi yebhokisi ukuze indlela yephutha ibe mfushane kuno-10 cm.Ngithumela incwadi yezincwadi zekhathuni enekhasi elilodwa ebhokisini ngalinye ukuze ngisho namaqembu abasebenzi basemini akwenze kahle.

Abafaki abaningi bayakhohlwa ukuhlola i-polarity. Izixhumi ze-DC zifana, kodwa isisekelo se-LKX-PV40 sino-“+” no-“–” obunjwe ngamagama agqamile. I-polarity ebuyela emuva ayibulali i-SPD, kodwa ifasitela lesikhombisi lingabonisa ubomvu ngisho noma ingxenye ilungile. Lelo fulegi elingamanga lichitha isikhathi se-O&M. Sifaka isitika esiphuzi esithi “Hlola i-polarity ngaphambi kokufaka i-clip-in.” Selokhu sengeze isitika, izinga lethu le-RMA lehle lisuka ku-1.2% laya ku-0.3%.

Uhlu lwezinyathelo ongalunamathisela ngaphakathi kwesivalo

1. Cisha iswishi ye-DC
2. I-voltage ye-open-circuit yokuhlola yentambo
3. Intambo yokudonsa engu-8 mm
4. Faka i-port kanye ne-torque engu-1.5 Nm
5. Imodyuli yesiqeshana
6. Vala isivalo
7. Vula
8. Hlola ukuthi ifasitela liluhlaza

Ngigcina ividiyo emfushane yalezi zinyathelo eziyisishiyagalombili efonini yami; Ngiyithumela kubaphathi besayithi uma becela ifayela lokuqeqesha. Isiqeshana sonke singamasekhondi angu-38, ngakho-ke sisebenza nakumanethiwekhi e-3G ahamba kancane ezindaweni zasemakhaya zaseNdiya.

Amanani Aphezulu kanye Nezinketho ze-OEM Zabasabalalisi kanye Nabahlanganisi Bezinhlelo?

Umsabalalisi eJordani ungithumelele i-imeyili ngo-2 ekuseni ecela ama-pcs angu-8,000 anelogo yakhe kanye nelebula lesi-Arabhu; sathumela ngezinsuku ezingu-18 futhi usaphinda ama-oda njalo ngekota.

Sinikeza amanani amakhulu ngama-break angu-500, 2,000, kanye no-10,000, siphrinta ilogo yakho kanye nenombolo yengxenye endlini, futhi singapakisha amayunithi ayishumi nambili ebhokisini elincane ukuze ulayishe ama-pcs angu-9,600 nge-HQ engu-40 esikhundleni se-7,200 evamile.
