Me whai parenga ngaru koe?
Kei te maumahara tonu ahau ki te haunga o te kirihou kua tahuna i te wā i para ai te inverter a tetahi kiritaki i te tau 2019. E 28,000 USD te utu mō taua pikinga kotahi, ā, e ono wiki te roa o te wā kore mahi.
Āe, me whai koe i tētahi parenga ngaru.Mā te pānga kotahi o te uira, mā te hapa whatunga rānei ka taea te tuku mano tini o ngā volts ki roto i ō taura. He pai te SPD ka pau taua pūngao i mua i te taenga atu ki tō inverter, mita, pākahiko rānei. Kua kite ahau i a ia e whakaora ana i ngā tuanui pūngao rā katoa.
Kāore anō kia tino mōhio? Pānui tonu. Māku koe e ārahi i roto i ngā pakaru tūturu, ngā tau tūturu, me ngā whakaritenga tika e whakamahia ana e mātou ina tukuna ana ki Berlin, ki Milan rānei.
Ka aha mēnā kāore he Kaitiaki Ngaru?
I whakatuwheratia e au te pouaka whakarewa, ā, i rite te PCB ki te tōhi pango. I whakaaro te kiritaki ka utua e te inihua. Kāore.
Ki te kore he SPD, te nui o te ngaohiko ka piki tika atu ki roto i tō inverter.Ka pahū te pūnga hononga DC, ka poto ngā IGBT, ā, ka mutu te aho katoa. Ka taea e te titi kotahi 1 500 V te whakakore i te kaitahuri arumoni 50 000 USD i roto i te 0.2 hēkona.
Wehenga Utu Tuturu
| Pūwāhi Kino | Utu Noa (USD) | Wā Arataki | Utu Huna |
| 100 kW hurihuri | 28,000 | 8–12 wiki | Ngaro te FIT |
| Pūhiko 20 kWh | 14,000 | 6 wiki | Tāuta anō |
| Te ngaronga o te whakaputanga | 4,200 / wiki | – | Ngā rarangi whiu |
He aha i kore ai e hinga te Breaker
Ka tauhohe noa ngā kaiwawao ki te nui rawa o te au, ehara i te nui rawa o te ngaohiko. Ka taea e te pūwero te 2 000 V engari 3 A anake, nō reira ka menemene te kaiwawao, ka noho kati tonu. Koia te take me whai taputapu koe e titiro ana ki te ngaohiko, ehara i te iahiko. Ko te mahi tonu a te SPD koia tēnei: ka whakapoto i ngā ngaohiko tāpiri ki te whenua, kātahi ka tautuhi anō.
Ngā Kōrero Pakiwaitara e Toru e Rongo Ana Au i Ia Wiki
- "Kua honoa aku panera ki te whenua."
Ka whakaitihia te ngaohiko pā e te whenua, engari kāore e mau i te titi.
- "Kāore rawa he uira e whiti ana i konei."
Ka piki haere te tere o te whakawhiti whatunga, ngā pēke pūnga, tae noa ki ngā motuka ararewa i ia rā.
- "He parenga ā-roto kei roto i te inverter."
Ko te nuinga o ngā MOV wheketere he 40 J te rahi. Ko te taumaha o tētahi patunga tika he 50,000 J. He pouri te pāngarau.
Take mai i Hamburg, Maehe 2023
Kāore he SPD o waho o tētahi tuanui 2 MW. Nā te pānga mai i tawhiti i puta ai te 1 200 V i runga i te aho DC. I mate te inverter, engari ko te mea kino rawa atu, i pakaru te tuanui polymer i te pewa. I uru mai te wai, ā, i whakapae te kamupene inihua i te "kore tiaki." Utu: kore. I muri mai ka hokona e te kiritaki te 120 o ā mātou SPD DC 1 000 V mō te hanga anō.
Take Wera Huna
He maha ngā miihini e wareware ana kei roto i tētahi pouaka IP65 iti te SPD i te rā katoa. Ka tunua te konganuku e te rā ki te 70 °C. I roto, ka wera ake te oma o te kōpae MOV. Ka tīmata ngā kōpae iti te turuturu i te iahiko i te 85 °C. Kia tīmata te turuturu, ka piki te wera, ka piki te iahiko, ā, ka pakaru te kōpae. Ka tāpirihia e tā mātou wheketere he hononga wera e kukume ana i te SPD ki waho i te ipurangi i te 120 °C. Ka rahua te waeine me te haumaru, kāore e poto, ā, ka haere tonu tō pae.
Ngaronga Tohu vs. Mōrearea Ahi
Ko te taumata tiaki hiko anake te tirohanga a ētahi kaihoko. Ka titiro anō hoki ahau ki te haumaru ahi. I te tau 2021 i wera tētahi whare putunga i Netherlands nā te mea i mura tētahi SPD kore ingoa i muri i te pakaru o te MOV. I whakakahore te kaiinihua ki te utu nā te mea kāore he rārangi UL 1449 4th Edition a te SPD. Ka whakamātauhia e mātou ia puranga ki te IEC me te UL kia taea ai e koe te moe i te pō.
Me pēhea te whiriwhiri i te parenga ngaru tika mō ngā kaupapa pūngao rā
I te tau kua hipa i tukuna mai e tētahi kaihoko he RFQ 20-whārangi. I mea te rārangi tuatahi: "SPD iti rawa te utu, 1 000 pcs." I mukua e au te īmēra.
Tātaitia te SPD ki te ngaohiko o tō pūnaha, te iahiko ara-poto, me te taumata mōrearea.Tīmata ki te IEC 61643-31. Kōwhiria he Uc 20% i runga ake i tō ngaohiko ara iahiko tuwhera. Kātahi ka tirohia te Imax: 40 kA mō ngā tuanui, 100 kA mō te tauine ratonga. Ka tāpirihia e au he whakapā mamao kia kite ai te tīma SCADA i te haerenga.
Ripanga Kōwhiringa Tere
| Momo Pūnaha | Uc(VDC) | Imax(kA) | Akomanga | Tohu Mamao |
| tuanui 600 V | 720 | 40 | II | Āe |
| aho 1 000 V | 1 200 | 60 | II+III | Āe |
| 1 500 V ratonga | 1 800 | 100 | I+II | Āe |
Tikanga Hipanga-i-te-Taumata
- Tuhia te kupu Voc i te rā makariri rawa.
Ka whakanuia e te makariri te ngaohiko tae atu ki te 15%.
- Tāpirihia he tawhē haumaru 20%.
Ka hoatu e tēnā ki tō Uc.
- Tatauhia te roa o te ara iahiko.
Mena he roa ake i te 10 m, tāpirihia he SPD tuarua ki te taha hurihuri.
- Tirohia te fiusi.
Me whai fiusi te SPD ka wetekina i mua i te rewa o te taura. Ka whakamahia e mātou te gPV 15 A mō te 4 mm².
- Pūrongo whakamātautau tono.
Pātai atu mō te IEC 61643-11 me te UL 1449 4th Edition. i roto i te PDF kotahi. Kāore he pūrongo, kāore he whakaaetanga.
Ngā Taipitopito Huna: Te Rerenga Wera
Ka tīmata te turuturu o ngā poraka MOV iti te utu i te 85 °C. I roto i tētahi pouaka pango IP65 i runga i te tuanui Pāniora, ka tupu tēnei i ia raumati. Ka whakamahia e ā mātou poraka te momotu wera e mau ana i te 120 °C. Ka rahua te SPD me te haumaru, ehara i te mea poto.
Hapa Roa Arataki
Ka kite ahau i ngā kaiwhakauru e whakamahi ana i ngā taura rere 30 cm nā te mea he tere ake. Ka tāpirihia e tēnā he 300 V ki te ngaohiko tuku-ā-roto. Ko tā mātou ture: kia iti iho ngā taura i te 15 cm katoa, ka takai rānei kia kore ai e whakamahia te hiko. I tapahia e tētahi kiritaki ngā taura mai i te 25 cm ki te 10 cm, ā, ka kite i te hekenga o te hiko mai i te 1.6 kV ki te 1.1 kV. I ora tana inverter i te awha i muri mai.
Te mahi tahi me AC Side
Kaua e wareware ki te taha AC. Whai muri i te hurihanga o te inverter ki te 400 V AC, me whai tonu koe i tētahi SPD. Ka whakanohoia e mātou ngā waeine AC Akomanga II 275 V ki te papa matua. Mō ngā wāhi he transformers, ka tāpirihia e mātou te Akomanga I 25 kA 10/350 µs ki te taha LV. Kotahi te whiunga i te raina MV ka taea tonu te heke iho.
He aha ngā EPC Matua e whakamahi ai i ngā hoahoa SPD ranu
I toro atu ahau ki tētahi EPC tekau o runga rawa atu i Milan. I hurihia e tā rātou miihini te SPD, ā, i mea ia: "Kāore au e hiahia kia tunua he hupa MOV ki taku wheketere."
Ka hono ngā SPD ranu ki tētahi ngongo hau tere me te MOV pakari. Ka tangohia e te ngongo hau te 90% tuatahi o te whiunga, nō reira ka noho mātao te MOV. Hua: ka toru te roa o te ora, ka heke te ngaohiko tuku-mā te 30%. Koia te take e tuhi ai ngā EPC Tier-1 i te "ranu anake" ki roto i ā rātou BoQ.
I roto i te Pouaka Ranu
| Atamira | Huānga | Tūmahi | Te ora (ngā whiunga) |
| 1 | Pūmau hau |
| 200 |
| 2 | MOV | Ngā toenga o ngā rawhi | 150 |
| 3 | Pūwero wera | Haumaru ahi | 1 haerenga |
He aha te mea nui mō te O&M
Ko te utu mō ia rōra taraka he 1,200 USD. Mēnā ka roa te SPD mō ngā tau 15, kaua mō ngā tau 5, ka penapenahia e koe kia toru ngā rōra. Mō tētahi putea 100 MW, arā, he 360,000 USD. Ko te 12 USD tāpiri ka utua e koe mō te hiko ranu he haruru.
Ngā Whakatakotoranga e Kite Ana Au i ngā RFQ o te tau 2024
- Te tukunga ingoa i roto i: 20 kA
- Te tukunga mōrahi Imax: 100 kA
- Taumata tiaki ngaohiko Runga:
- Whakapā mamao: maroke 250 V 1 A
- Pāmahana whakahaere: –40 °C ki te +85 °C
- Tiwhikete: IEC, UL, TÜV, CE, RoHS
Ki te kore e taea e tō wheketere te whakatutuki i ngā whakaritenga katoa, kua kore koe e eke ki te taumata e hiahiatia ana.
Te Āwhiowhio o te Ngongo Hau me te Āwhiowhio o te MOV
I whakahaerehia e mātou he whakamātautau 20 kA 8/20 µs e 200 ngā wā. I kite te waeine MOV parakore i te pikinga ake o te 38% i muri i te 100 pupuhi. Ko te waeine ranu i piki ake i te 9% anake. Ko te tikanga o taua delta ka kite te inverter i te 400 V iti iho te ahotea. Neke atu i te 20 tau, koinei te rerekētanga i waenga i te roanga o te ora o te inverter 12-tau me te whakawhiti 6-tau.
Tohutohu Taumaha
E 0.8 kg te taumaha o tētahi SPD ranu 40 kA nā te mea ka tāpirihia he parahi me te uku ki te ngongo hau. E 0.4 kg te taumaha o tētahi waeine MOV-anake 40 kA. Ki te māmā te ahua o te tauira, whakatuwheratia. Tērā pea ka kitea e koe kua ngaro te haurua o ngā kōpae MOV.
Mai i te Wheketere ki te Marae: He aha te mea e hanga ai he Kaiwhakarato SPD Pono?
I arotakehia e au tētahi awheawhe i whakapirihia ai ngā MOV ki te epoxy. I te tau i muri mai ka taka ngā poraka i te wā o te tuku. E 800 ngā waeine i ngaro i te moana.
Ko te kaiwhakarato SPD pono te rangatira mō te mekameka katoa: te toa whakarewa, te mīhini perehi kōpae MOV, te whakarewa TIG, te tahu-ā-roto, me te whakamātautau 100%.Pātai atu mō te pepa QC. Me whakaatu te In me te Imax mō ia waeine, kaua ko te tauira puranga. E 10 tau te roa o te pupuri a taku wheketere i Wenzhou i aua raraunga.
