Kei te maumahara tonu ahau ki te wā tuatahi i whakatuwhera ai ahau i tētahi Pouaka whakakotahi DC i Arizona; i kī mai te haunga tahunga kua pekehia e mātou te taha matau ārai ngaru.

He rite te āhua o te parenga ngaru ki tētahi pereki hina iti me ngā pito whakarewa, he matapihi tohu whero, kakariki rānei, me tētahi tapanga tānga e whakaatu ana i te ngaohiko, te iahiko, me te tohu CE.I tango whakaahua ahau i tā mātou LKX-PV40, ā, e rua tekau ngā īmēra e penapenahia ana e ahau mō ia waeatanga hoko mā taua whakaahua kotahi.

Ki te hoko koe i ngā wāhanga pūngao rā i ia hauwhā, panuku tonu; ka whakaaturia e ngā wāhanga e whai ake nei he aha te āhua me ngā āhuatanga e whakatau ana mēnā ka whiwhi moni, ka whakapau moni rānei tō paetukutuku.

LKX-PV40: Mahi Tino Pai Kaitiaki Ngaru DC mō Ngā Pūnaha Rā?

E ono ngā waitohu i whakamatauria e au i roto i tā mātou taiwhanga Wenzhou, ā, ko te LKX-PV40 anake i pupuri i te ngaohiko kume i raro i te 1 kV i muri i ngā pupuhitanga 40 kA e toru.

He parenga hiko DC mono te LKX-PV40, he 800 V te whakatauranga, 20 kA, 40 kA te mōrahi, he 3.6 kV te here, ā, ka uru ki tētahi rēra DIN paerewa 35 mm i roto i ngā pouaka whakakotahi hiko pūngao rā.Ka rongoatia e au ki roto i te whare hina, pango rānei, ā, ka tukuna i roto i ngā rā e whitu mai i tā mātou wheketere 2,000 m² te rahi.

He maha ngā pātai a ngā kaihoko ki ahau he aha mātou i whakamahi ai i te ngongo hau me te MOV ranu. He māmā noa te whakautu: ka pā te ngongo hau ki te tuatahi, ka oti te mahi a te MOV, ā, ka ora te kōwae i ngā pupuhi maha atu. Mā taua huinga ka whakaitihia ngā haerenga whakakapinga ki te haurua i ngā wāhi ratonga kei reira te utu o ngā kerēne i te taputapu tonu.

Ngā wāhanga matua ka kitea mai i waho

Ka hangaia e mātou te whare i roto i te whare kia taea ai e mātou te tāpiri i tō waitohu, te whakarerekē rānei i te tae me te kore he taputapu hou. I te tau kua hipa, i hiahia tētahi EPC Tiamana ki ngā whare karaka kia rite ki tā rātou waitohu; e 3,000 ngā wahi i tukuna e mātou i roto i ngā rā tekau mā rima.

He kōrero hiko kei muri i te pouaka iti

Ka whakahaerehia e au ēnei whakamātautau i ia puranga. Ka puritia e mātou te pūrongo whakamātautau i roto i te kātene kia taea ai e tō rōpū QC te matawai i te waehere QR me te kite i te pdf taketake. Mā taua taahiraa iti ka whakakorea te āwangawanga "CE rūpahu" e pā ana ki te nuinga o ngā kaihoko ina hoko mai rātou i Haina.

He aha i whiriwhiri ai ngā EPC i te LKX-PV40 mō ngā kaupapa PV Tauine-Whare Whakahaere?

I ngaro i ahau tētahi utu whakaheke hiko Pōrana mā te 0.02 $/W nā te mea i mahue i taku hoa whakataetae te taputapu hiko whakarunga; i muri i ngā marama e ono, ka hokona e te EPC taua 5,000 ngā waeine LKX-PV40 i muri i te matenga o ngā inverters e rua i te tupuhi uira.

Ka whiriwhiria e ngā EPC te LKX-PV40 nā te mea ka tukuna mai i te whare putunga, ka tukuna he iahiko kua whakatauria he 20 kA e rite ana ki te nuinga o te whāngai whakamuri mōrahi o te inverter, ā, mā te kōwae mono ka taea te whakawhiti wāhanga i raro i te kotahi meneti me te kore e hono anō i te waea.Ka tautokohia e au ia waeine me te pūtāhui e rima tau me te oati whakakapinga 24-hāora mai i tā mātou pokapū wāhanga tāpui o Hamburg.

E rua ngā hoariri e pā ana ki ngā wāhi nui: te uira me te wā whakatā. Ko te kotahi haora o te kore putanga i runga i te wāhi 100 MW e pau ana i te 25,000 €. Mā te LKX-PV40 ka iti te wā whakatā i roto i ngā huarahi e toru: tuatahi, ka motu te momotu wera i mua i te rewa o te whare, kia kore ai e horapa te hapa; tuarua, ka puta te kōwae pērā i te pereki Lego, nō reira he tīwiri anake e hiahiatia ana e te kapa O&M; tuatoru, ka tāia e mātou te tau wāhanga ki te turanga me te kātere, kia kore ai e whakaranua ngā puranga tawhito me ngā puranga hou.

Te pāngarau utu o te mana pupuri e arohaina ana e ngā CFO

I whakaaturia e au tēnei ripanga ki a Jeff Weaver, he kaiwhakahaere hokohoko o Amerika, i te wā o tētahi waea Zoom. Kotahi te rārangi i whakautu mai ai ia: "Tukua mai kia 2,000 ngā wahi CIF Houston." He nui ake te kōrero o te pāngarau i tētahi atu pukapuka iti.

He aha ngā āhuatanga hangarau e whai tikanga ana ki ngā tīma hoko pūngao rā?

I kite ahau i tētahi wāhi 30 MW i Itari e kore e pai te tirotiro nā te mea ko te 600 V anake i rārangihia i runga i te tapanga SPD; i hiahia te kaitirotiro ki te 1,000 Vdc, ā, i whakatikahia e mātou ki te LKX-PV40 i roto i ngā rā e rua.

He mea nui ki ngā kaihoko pūngao rā te Ucpv 800 Vdc hei taupoki i ngā aho 1,500 V i te pāmahana e rua tekau nekehanga te roa, i roto i te 20 kA kia kore ai te taputapu e pakaru i te teitei, me te tapuwae mono-mai e ōrite ana ki ngā turanga MidNite Solar me ABB kia taea ai e rātou te whakaranu i ngā waitohu i roto i te pouaka kotahi.Ka tāia e au ēnei rārangi e toru ki te whārangi o mua o ia kōrero.

Kei roto i te Excel ngā tīma hoko. Ka whakarōpūhia e rātou ngā pou mā te utu, te MOQ, me te wā arahi. Ka tāpirihia e au ētahi pou huna e rua: "tiwhikete tūturu, rūpahu rānei" me te "tawhiti o te wheketere ki te tauranga." Kotahi te haora o Wenzhou mai i te tauranga o Ningbo, nō reira ka utaina ā mātou ipu i te Mane ka rere i te Tūrei. Ka tapahia e taua ara poto te utanga mā te 4% ki ngā wheketere o uta. He uaua ake te kaupapa tiwhikete; he maha ngā kaiwhakarato e whakaatu ana i tētahi pepa CE 2016 kua pau te wā. Ka whakahoutia e mātou tā mātou pūrongo TUV i ia tau, ka tukuatu ki tā mātou tūmau kia taea ai e ngā kaihoko te tirotiro i te rā ipurangi.

Te tikanga o ngā whakarāpopototanga i roto i ngā kupu māmā

- Ucpv: te ngaohiko dc teitei rawa atu ka taea e koe te hono atu ake ake me te kore e mura te SPD

- I roto: te au ka taea e te SPD te horomi i ngā wā 20, ā, kei te mahi tonu

- Imax: te iahiko kotahi-pana nui rawa atu ka taea e te SPD te tango i mua i tōna matenga

- Ki runga: te ngaohiko e paheke tonu ana ki tō inverter; he pai ake te iti iho

Mena he 3.6 kV te Up, ā, ka taea e tō inverter te tango i te 4 kV, he 0.4 kV te tawhiti haumaru. I ngā ata makariri ka piki ake te ngaohiko ara iahiko tuwhera o te panera, ā, ka heke iho taua tawhiti. Ka kī atu ahau ki ngā kaihoko kia whiriwhiria he SPD kei raro iho i te 80% o te whakatauranga ngaru inverter te Up. Nā taua ture i whakaora tētahi kaupapa 50 MW i Texas i te hotoke kua taha ake nei.

Mai i te Whārangi Whakatakotoranga ki te Pae: Me pēhea te Tāuta i te LKX-PV40 ki ngā Pouaka Whakakotahi?

I tau ahau ki Chile me taku peke tuara me te taraiwa taipana anake; i te tina kua oti i ahau me te kapa te whakauru i ngā waeine LKX-PV40 e 120, ā, i paahitia e te wheketere ngā whakamātautau HV i taua rā anō.

Tāutahia te LKX-PV40 mā te whakapiri i te turanga ki te reri DIN 35 mm, whakakorikoria ngā waea PV ki te 1.5 Nm i roto i ngā putanga 4 mm², tapatapahia te kōwae kia rongo rā anō koe i te pāwhiri, kātahi ka arahi i te waea whenua mā roto i te pae-pahi pouaka kia poto ake te ara hapa i te 10 cm.Ka tukuna e au he pukapuka pakiwaituhi kotahi whārangi ki roto i ia kātene, nō reira, ahakoa ngā tīma mahi o ia rā, ka taea tonu e rātou te mahi tika.

He maha ngā kaiwhakauru e wareware ana ki te tirotiro i te polarity. He rite tonu te āhua o ngā hononga DC, engari he "+" me te "–" te mea i whakairohia ki ngā reta matotoru ki te turanga LKX-PV40. Kāore te polarity whakamuri e whakamate i te SPD, engari tera pea ka whero te matapihi tohu ahakoa he pai te wāhanga. Ka moumou te wā O&M i taua haki teka. Ka tāpirihia e mātou he tapanga kōwhai e kī ana "Tirohia te polarity i mua i te topenga." Mai i te tāpiritanga o te tapanga, kua heke te reiti RMA mai i te 1.2% ki te 0.3%.

Rārangi taahiraa ka taea e koe te tāpiri rīpene ki roto i te taupoki

1. Whakawetohia te pana DC
2. Ngaohiko ara iahiko tuwhera aho whakamātautau
3. Waea rīpene 8 mm
4. Whakauruhia ki te tauranga me te taipana 1.5 Nm
5. Kōwae topenga
6. Katia te taupoki
7. Whakakāhia
8. Tirohia mēnā he kākāriki te matapihi

Kei te pupuri ahau i tētahi ataata poto o ēnei kaupae e waru i runga i taku waea; ka tukuna e au ki ngā kaiwhakahaere o te papaanga ina tono mai rātou mō tētahi kōnae whakangungu. E 38 hēkona te roa o te ataata katoa, nō reira ka mahi anō hoki i runga i ngā whatunga 3G puhoi i ngā taiwhenua o Īnia.

Ngā utu papatipu me ngā kōwhiringa OEM mō ngā kaituku me ngā kaiwhakauru pūnaha?

I īmēra mai tētahi kaihokohoko i Hōrana ki ahau i te 2 i te ata e tono ana kia 8,000 ngā hua me tana waitohu me te tapanga Ārapi; i tukuna atu e mātou i roto i ngā rā 18, ā, kei te tono anō ia i ia hauwhā.

Ka tukuna e mātou he utu nui mō ngā wehenga 500, 2,000, me te 10,000 ngā wahi, ka tāia e mātou tō waitohu me tō nama wāhanga ki runga i te whare, ā, ka taea e mātou te tākai i ngā wahi tekau mā rua ki roto i tētahi kātene angiangi kia utaina ai e koe he 9,600 ngā wahi mō ia 40 HQ, kaua ki te 7,200 noa.
