Isixazululo Sesistimu Ye-Solar Photovoltaic

I-JZP Transformer ingumholi womhlaba wonke ekukhonzeni umkhakha wamandla avuselelekayo emhlabeni jikelele. Ngomlando oqinisekisiwe, sihlinzeke ngezinkulungwane zama-transformer kumaphrojekthi okugcina i-photovoltaic kanye nokugcina amandla kulo lonke elaseNyakatho Melika, eYurophu nase-Australia. Imikhiqizo yethu ayihlangabezani nje kuphela nezindinganiso eziqinile njenge-IEEE, ANSI, CSA, AN, IEC, kanye ne-BS, kodwa futhi inezitifiketi ezifaka phakathi i-UL, cUL, CSA, CE, SGS, nezinye, ezisekelwa yimibiko yokuhlola ephelele.

Ukusebenza kahle, ukwethembeka, kanye nokuphepha yizimiso eziyisisekelo esizinamathela ngokungaguquki.

Izidingo ze-SG250HX Transformer

1) I-transformer kumele ifaneleke ukusebenza ne-inverter evunguzayo.

2) Uma kusetshenziswa isisombululo esilwa ne-PID (ukuwohloka okungenzeka okubangelwa), ama-windings e-transformer secondary kumele akwazi ukuphatha i-Vrms=906V VAC peak voltage reference emhlabathini ohlelweni lwe-1500V. Uhlangothi lwe-LV lwe-transformer kanye ne-voltage eqhubekayo ephezulu yamadivayisi okuvikela umbani ohlangothini lwe-LV lwe-transformer kufanele ahambisane nale mfuneko.

3) I-voltage yokuphuma ye-SG250HX ingu-800Vac LL (640~920Vac), 50Hz noma 60Hz. I-voltage ohlangothini lwe-MV kufanele ihambisane ne-voltage yegridi ye-MV endaweni yokuxhuma, i-transformer ene-tap changer iyathandwa.

4) Umthamo we-transformer kumele uhambisane namandla okukhipha aphezulu kakhulu e-Inverters

5) Kuzosetshenziswa i-transformer ehlukaniswe kabili (emibili ye-LV, eyodwa ye-MV side), kudingeka ama-winding amabili e-LV.

Kungasetshenziswa ukuxhumeka kwe-Dy11y11. Kuzosetshenziswa i-transformer ephindwe kabili (eyodwa ye-LV, enye ye-MV side), kudingeka ukujikeleza kwe-LV okukodwa, futhi kungasetshenziswa ukuxhumeka kwe-Dy11.

6) I-voltage ye-Impedance Z(%) kumele ihambisane nezidingo ezijwayelekile ezihlobene. Njenge-IEC 60076 noma i-IEEE C57.12.34 kanye ne-C57.12.00.

7) I-transformer kufanele ikwazi ukumelana nezinga elithile lamandla ahambisanayo, inani eliphezulu lamandla ahambisanayo lingu-5% wamandla ayisisekelo ngamandla ajwayelekile.

8) I-transformer kufanele imelane nezinga elithile lengxenye ye-DC, u-0.5% wamandla ayisisekelo ngamandla ajwayelekile.

9) I-transformer kufanele imelane nokungalingani kwesigaba esithile, u-5% wamandla kagesi ngamandla ajwayelekile.

10) Ukugoqa kwe-LV kwe-MV transformer kufanele kumelane ne-voltage gradient dU/dt efika ku-500V/μs emhlabathini.

11) Isivikelo esihle kanye nokuhlukaniswa phakathi kwama-winding e-LV kanye ne-MV.

12) I-transformer kumele isekelwe endaweni eyodwa kuphela, futhi isisekelo se-transformer kumele siqine.

13) Isigaba sokushisa kufanele okungenani sibe ngu-F I-Transformer Yohlobo Olomiles kanye no-A kohlobo lwamafutha.

Izinga lokushisa eliphezulu (℃) 105 120 130 155 180 200 220

Ukuphakama kwezinga lokushisa kokugoqa (K) 60 75 80 100 125 135 150

14) Ukusebenza kahle kwesisindo somthwalo kufanele kuhambisane nezidingo zakamuva zendawo.

15) Indawo ezungezile (izinga lokushisa, umswakama, ukuphakama, umoya, njll.) kufanele icatshangelwe.

16) Ukwenyuka kwezinga lokushisa kanye nokususwa kukagesi okuncane kufanele kucatshangelwe ikakhulukazi uma ukuphakama kungaphezu kuka-1000m.

17) Imvamisa yegridi yezwe kanye nezindinganiso kumele zihlonishwe.
