Ngā Otinga SPD Pūngao Rā Atamai mō ngā Pūnaha PV Haumaru ake i te tau 2025
Kei te maumahara tonu ahau ki te rā i whakangaromia ai e te uira kotahi te 40% o ngā inverters tuanui o taku kiritaki. Nā tēnei mate nui i whakanui te hiranga o te tāutanga ngā taputapu tiaki ngaru atamai (SPD)) mō ia panera rā, kia pai ai te mahi ahakoa ngā tupuhi kino.
E whakahaere ana ahau i tētahi whenua 2,000 m² SPD pūngao rā atamaiwheketere i Wenzhou, ā, ka tukuna e au ngā waeine mono-whakakapi ki Tiamana, ki Parani, ki te US me Īnia. I te tau 2025, ko te mea tino atamai ngā taputapu tiaki ngaru o te rā (SPD)whakakotahi i ngā whakatauranga hiko dc 1,000 V,aroturuki kapua wā-tūturu ngā āheinga, me ngā kātere whakawhiti-wera e tapahi ana i ngā rōra taraka mā te 70%. Māku e whakaatu ki a koe me pēhea te whiriwhiri, te whakanoho me te whakamana i a rātou kia tino tiakina ai tō pūnaha.
Mena he kaihoko koe e kino ana ki ngā mea ohorere, me noho ki konei. Mā ngā wāhanga e whai ake nei ka ārai i a koe i ngā hapa o te mara, ngā kereme utanga me ngā īmēra riri mai i te kapa o te pae.
He aha ai Te Parenga Pupuhi Ngā Take mō ngā Pūnaha Hiko o te Rā
I te marama o Hune kua taha ake nei, i mātakitaki ahau i te ngaronga o tētahi papa hiko 2 MW i tētahi EPC nā te mea i mahue i a ia te te tiaki i ngā ngaru mō ngā pūnaha solarhei penapena i te USD 0.01 mō ia watt. I pau i a ia te USD 180,000 mō ngā inverters i te tupuhi tuatahi.
Ka tiakina e au aku kaupapa ki Ngā taputapu tiaki ngaru momo 1+2 (SPD)nā te mea ka taea e te uira kotahi te pana i te 50 kA ki roto i ngā taura aho PV. Ki te kore te tikate tiaki uira mō ngā pūnaha solar, ka tunua e taua pūngao ngā pouaka hononga, ngā arotau me ngā kaitahuri. Mā te waeine tika, ka nekehia e au te 99% o te ngaru ki te whenua, ā, ka whakahaere tonu i te tipu.
Ehara i te taputapu para te utu tuturu o te ngaru nui
He tīmatanga noa iho te hurihanga parai. Ka ngaro aku kiritaki i Texas USD 1,500 ia rāmō ia wāhanga 100 kW tuimotu. Mena ka whakaroahia te tono a te OEM mō ngā wiki e ono, ko taua USD 120 iti taputapu tiaki ngaru o te rā (SPD)kātahi ka rite ki te utu pai. Ki te kore he tika te tiaki i ngā ngaru mō ngā pūnaha solar, ka nui te utu mō te wā kore mahi me ngā mahi whakatikatika.
Te urunga puku o ngā ngaru ki roto i ngā ara iahiko PV
He onge ngā pānga tika. Ko te nuinga o ngā kino ka puta mai i ngā ngaru whakaawe e rere ana i runga i ngā oma roa DC. Ka inehia e au ki te taputapu hopuoro Fluke; ka puta mai ngā titi 6 kV i te 30 kiromita te tawhiti atu i te pokapū o te tupuhi. Koia ahau ka whakanoho i ngā SPD ki ngā pito e rua o te aho, ehara i te mea ki te inverter anake.
Ngā momo rahunga huna e ngaro ana i ngā kaihoko
Ka pakaru ētahi SPD. Mēnā kāore he momotu wera o te taputapu, ka mura i raro i te iahiko whai-ake 5 A. E tono ana ahau ngā paerewa tiaki ngarupērā i te tutuki i ngā whakaritenga o te UL 1449 putanga tuawhā me te whakatauranga SCCR 40 kA mō ia wāhanga ka tukuna e au. Kei te ripanga i raro nei ngā mea ka tirohia e au i mua i te wehenga atu o te kātene i taku tauranga.
| Wāhi tirotiro | Uara pāhi | Taku tikanga whakamātautau |
| Uc (Teitei tonu DC) | ≥ 1,000 V | Hipote 120% mō te 1 hāora |
| Ki runga (VPR i te 3 kA) | ≤ 1,800V | 8/20 µs te ngaru taiwhanga |
| Te rerenga wera | Kāore he ahi | 5 He whai muri, 30 meneti |
| Whakatauranga IP | ≥ IP65 | Whakamātautau ngongo, 3 meneti |
He aha te SPD Pūngao Rā, me pēhea te tiaki i ngā taputapu PV
I taku whakaaturanga tuatahi i tētahi SPD ki taku tamāhine, i mea ia he rite ki tētahi pereki hina me ngā waea. I kī atu ahau he pana tere e whakatuwhera ana i te tatau o muri mō te uira.
Ka hangaia e au ngā SPD o te rā me ngā varistor whakarewa-waikura me ngā ngongo hau. Ina eke te ngaohiko ki runga ake i te 1,200 V, ka piri ngā wāhanga ki te 25 ns ka tukuna te ngaru ki te whenua. Whai muri i te huihuinga, ka tautuhi anō te waeine, ā, ka whāngai tonu te rarangi ki te whatunga. Kāore aku kiritaki e kite i te wā whakatā i roto i te 95% o ngā whiunga.
I roto i te pereki hina
Iawāhanga tiaki ngaru o te rāI roto i taku wheketere, e whakamahia ana he kōpae MOV he 32 mm te tapawhā. E toru ngā kōpae e whakarārangihia ana e au kia eke ki te 1,000 Vdc. Kei runga i te kōpae o runga he fiusi wera; ki te eke te pāmahana ki te 120 °C, ka tuwhera te puna, ā, ka whero te rama LED. Mā tēnei ka kore te wāhanga pakaru e hono ki te pae pahi.
Te tiakitanga taumata aho me te inverter
Ka whakamahia e au te ahongā SPD o te pūnaha rāina roa ake te oma tuatahi i te 30 m. Mō ngā pūwhakawhiti waenga, ka whakairihia e au he whatanga-mau Te tiaki i ngā ngaru DC me ACte waeine i runga i te pahi DC me tētahi atu i runga i te putanga AC. Kei te ripanga i raro nei te ture whānui e tukuna ana e taku tīma ki ia kaihoko mā te īmēra.
| Rahi o te rarangi | Tauwāhi SPD | Wāhanga nama I ka tukuna |
| tuanui 5 kW | Aho, + me te – | LSP-1000DC-20 |
| 100 kW te taunga waka | pouaka whakakotahi | LSP-1000DC-40 |
| Maunga whenua 2 MW | Putanga pahi DC + AC | LSP-1000DC-100 + LSP-480AC-100 |
He aha ahau kāore ai e whakawhirinaki ki ngā fiusi "puku-whakatauranga" anake
Te tiaki i te ngaruHe mea nui te wā urupare. He puhoi ngā fiusi. Me 35 A te fiusi 15 A gPV mō te meneti kotahi hei whakatuwhera. I taua wā, kua wera kē te taraiwa kuaha inverter i te pū 6 kV.Ngā taputapu tiaki ngaru (SPD)Ka mahi ngā fiusi i roto i ngā nanohekona; ka mahi ngā fiusi i roto i ngā mirihekona. Ka whakamahia e au ngā mea e rua, engari kāore au e peke i te SPD.
Me pēhea te whiriwhiri i te SPD Pūngao Rā Tika mō tō Pūnaha
I tukuna e au te mea hē i tētahi wākōwhiringa SPD pūngao rāki tētahi wāhi i Florida. I whakamahia e te kaiwhakauru ngā waeine 600 V i runga i te aho 1,000 V. E toru marama i muri mai, ka poto ngā waeine, ā, ka tangohia te arai. Nā taua hapa i pau ai te $8,200 i roto i te utunga rererangi mō ngā whakakapinga.
Āhea te whiriwhiri i te SPD solar pai rawa atumō tō pūnaha, e toru ngā whakatakotoranga matua ka tauritehia e au: te ngaohiko pūnaha, te iahiko porowhita-poto, me te whakatauranga āhua ngaru. Mā tēnei ka whakarite kia taputapu tiaki ngaru o te rākua whirihorahia kia tino pai hei whakahaere i ngā huihuinga ngaru e tumanakohia ana.
Te whakatauranga ngaohiko: te tātari tuatahi
Kei roto i taku wheketere ngā tauira hiko 600 V, 1,000 V me te 1,500 V. Ka pātai atu ahau ki te kaihoko mō te ngaohiko ara iahiko tuwhera i te rā makariri rawa o te tau, kātahi ka tāpirihia he tawhē 20%. Mena he 850 V te VOC, ka peke atu ahau ki te wāhanga 1,000 V. Mā tēnei ka ārai i te pakaru o te here i ngā ata hotoke.
Te whakatauranga o te au me te pūngao: te tātari tuarua
Ka tirohia e au te iahiko poto-poto DC mōrahi o te inverter. Ko te tikanga o te fiusi aho 15 A ko te 20 kA Imax anake e hiahiatia ana e te SPD. Mō te inverter pokapū 1,500 V me ngā fiusi 240 A, ka peke atu ahau ki te 100 kA. Kei te whakaatu te ripanga i raro nei me pēhea taku mahere i te rahi o te fiusi ki te tau wāhanga.
| Whakatauranga fiusi | Hapa mōrahi | SPD Imax I whiriwhiria e au |
| 15 A | 25 A | 20 kA |
| 32 A | 50 A | 40 kA |
| 250 A | 400 A | 100 kA |
Aroturuki mamao: te whakahoutanga o te tau 2025
I tēnei tau i tāpirihia e au he maramara RS-485 ki roto i te SPD. Ka pānuihia e te inverter te tatau ngaru, te ia turuturu, me te pāmahana. Me aroturuki mamao SPD pūngao rā, ina eke te turuturu ki runga ake i te 1 mA, ka tukuna mai he īmēra e te tipu. Ka tukuna atu e au te kātere whakakapinga i mua i te pakaru o te waeine. He pai ki aku kaihoko i Tiamana tēnei nā te mea ka tangohia ngā takai taraka kāore i whakamaheretia.
Ngā Paerewa ā-Ao me te Whakatutukitanga mō ngā SPD Pūngao Rā
I ngaro i ahau tētahi tono tuku moni Wīwī nā te mea i whakaatu taku hoa whakataetae i tētahi tiwhikete tiaki ngarumai i TÜV, ā, he pepa taiwhanga Hainamana anake tāku. Nui atu te whakawhirinaki o te kaihoko ki te tānga Tiamana i aku raraunga. I ako ahau i tērā tiwhikete SPD pūngao rāhe rite tonu te hiranga ki te hua tonu.
Ka whakamanahia e au inaianei ia te tutuki i ngā whakaritenga SPD o te rāki te IEC 61643-31, UL 1449 4th, me te EN 50539-11. Ka hipokina e ēnei e toru ngā taha DC me AC, te haumaru ahi, me te EMC. Me ngā kōnae katoa, ka taea e au te whakaoti i ngā tikanga tāke i Hamburg, Los Angeles, me Mumbai i raro i te 48 hāora, me te whakarite kia tutuki i ia waeine te taumata teitei rawa atu. ngā paerewa ā-ao mō ngā SPD.
IEC 61643-31: te Paipera DC
Ka whakatakotohia e tēnei paerewa te ngaohiko 1.2/50 µs me te ngaru iahiko 8/20 µs. Me whakaatu e aungā paerewa whakamātautau SPD o te rārite ki te 3 kA me te pumau wera i te 5 A whai muri. E 20 ngā tauira ka whakahaerehia e taku taiwhanga i Wenzhou, ā, ka kiriatahia te whakamātautau. Ka tukuna e au te ataata ki Alibaba; e pai ana ngā kaihoko ki te māramatanga, ā, e whakawhirinaki ana ki tā mātou whakamātautau tiaki ngarungā tikanga.
UL 1449 putanga tuawhā: te kaitiaki kūaha o Amerika
E tono ana te UL kia 40 kA te whakatauranga iahiko poto me te whakamātautau haumākū 1,000-hāora. Ka rere au i ngā papa ki ngā taiwhanga UL i Suzhou i ia hauwhā kia tutuki ai ngā whakaritenga tiwhikete SPD solarKua tāia te nama kōnae ki te tapanga kia taea ai e Jeff i Texas te tirotiro i te ipurangi. Mā tēnei ka whakakorea te ruarua "i hangaia ki Haina", ka whakawhirinaki ngā kaihoko ki tā mātou ngā paerewa tiaki ngaru mō te tiwhikete UL.
EN 50539-11: te ara poto o te EU
Me tēnei tohu, ka hokona e au i roto i ngā whenua e 27, kāore he whakamātautau tāpiri. Ko te kaihoko Wīwī i whakakahore i ahau i te tau 2022 kua tono inaianei i te 4,000 pcs ia marama nā te mea i tāpirihia e au te tiwhikete solar SPD TÜVtohu. E 21 ngā rā tonu te roa o te wā arahi mai i te mahi.
Kaupapa CB me te whakamanatanga tahi
Ka honoa e au ngā pūrongo IEC me ngā tiwhikete CB. Mā tēnā ka taea e au te whakawhiti i ngā rerekētanga ā-motu i roto i te wiki kotahi. Ka whakaatuhia e taku pepa hoko ngā tohu taha ki taha; ka matawaihia e ngā kaiwhakahaere hoko ka neke atu. Ko ēnei ngā tiwhikete ā-ao o te SPD solarāwhina ki te whakahaere i te tukanga. Kei te ripanga i raro nei ngā tohu ka tukuna e au mā te taunoa.
