Yankho la Dongosolo la Solar Photovoltaic

JZP Transformer ndi mtsogoleri padziko lonse lapansi pantchito yotumikira gawo la mphamvu zongowonjezwdwa padziko lonse lapansi. Ndi mbiri yotsimikizika, tapereka ma transformer zikwizikwi a mapulojekiti osungira mphamvu ndi ma photovoltaic ku North America, Europe, ndi Australia. Zogulitsa zathu sizimakwaniritsa miyezo yokhwima monga IEEE, ANSI, CSA, AN, IEC, ndi BS, komanso zili ndi ziphaso kuphatikizapo UL, cUL, CSA, CE, SGS, ndi zina, zothandizidwa ndi malipoti athunthu a mayeso.

Kuchita bwino, kudalirika, ndi chitetezo ndi mfundo zazikulu zomwe timatsatira mosalekeza.

Zofunikira pa Transformer ya SG250HX

1) Transformer iyenera kukhala yoyenera kugwiritsidwa ntchito ndi inverter yoyendetsedwa ndi pulsed.

2) Ngati njira yotsutsana ndi PID (kuwonongeka komwe kungachitike) ikugwiritsidwa ntchito, ma windings achiwiri a transformer ayenera kukhala ndi mphamvu yogwiritsira ntchito Vrms=906V VAC peak voltage reference pansi pa dongosolo la 1500V. Mbali ya LV ya transformer ndi mphamvu yopitilira ya zida zotetezera mphezi kumbali ya LV ya transformer ziyenera kutsatira izi.

3) Voliyumu yotulutsa ya SG250HX ndi 800Vac LL (640~920Vac), 50Hz kapena 60Hz. Voliyumu yomwe ili kumbali ya MV iyenera kugwirizana ndi voltage ya gridi ya MV pamalo olumikizira, transformer yokhala ndi chosinthira cha tap ndiyo yabwino kwambiri.

4) Mphamvu ya transformer iyenera kugwirizana ndi mphamvu yayikulu yotulutsa ya Inverters

5) Transformer yogawanika kawiri (iwiri ya LV, imodzi ya mbali ya MV) iyenera kugwiritsidwa ntchito, ma windings awiri a LV akufunika.

Malumikizidwe a Dy11y11 angagwiritsidwe ntchito. Transformer yozungulira kawiri (imodzi ya LV, ina ya mbali ya MV) iyenera kugwiritsidwa ntchito, kuzunguliridwa kamodzi kwa LV kukufunika, ndipo malumikizidwe a Dy11 angagwiritsidwe ntchito.

6) Voliyumu ya Impedance Z(%) iyenera kutsatira zofunikira zina. Monga IEC 60076 kapena IEEE C57.12.34 ndi C57.12.00.

7) Transformer iyenera kukhala yokhoza kupirira mulingo winawake wa mphamvu ya harmonic, mphamvu yonse ya harmonic ndi 5% ya mphamvu ya fundamental pa mphamvu ya nominella.

8) Transformer iyenera kupirira mulingo winawake wa gawo la DC, 0.5% ya mphamvu yoyambira pa mphamvu yodziwika.

9) Transformer iyenera kupirira kusalingana kwa gawo linalake, 5% ya mphamvu yamagetsi pa mphamvu ya nominella.

10) Kuzungulira kwa LV kwa transformer ya MV kuyenera kupirira kukwera kwa voltage dU/dt mpaka 500V/μs pansi.

11) Chishango chabwino komanso cholekanitsa pakati pa ma windings a LV ndi MV.

12) Transformer iyenera kukhazikika pamalo amodzi okha, ndipo maziko a transformer ayenera kukhala otetezeka.

13) Gulu loteteza kutentha liyenera kukhala osachepera F pa Transformer Youmas ndi A za mtundu wa mafuta.

Kalasi yotetezera kutentha AEBFHNC

Kutentha kwakukulu (℃) 105 120 130 155 180 200 220

Kukweza kutentha kwa kuzungulira (K) 60 75 80 100 125 135 150

14) Kulemera koyezedwa bwino kuyenera kutsatira zofunikira zaposachedwa za m'deralo.

15) Malo okhala m'deralo (kutentha, chinyezi, kutalika, mpweya, ndi zina zotero) ayenera kuganiziridwa.

16) Kukwera kwa kutentha ndi kutsika kwa magetsi ziyenera kuganiziridwa makamaka pamene kutalika kuli pamwamba pa 1000m.

17) Mafupipafupi a gridi ndi miyezo ya dziko lililonse iyenera kutsatiridwa.
