Kev daws teeb meem ntawm lub hnub ci photovoltaic system

JZP Transformer yog ib lub tuam txhab ua lag luam thoob ntiaj teb uas muab kev pabcuam rau lub zog rov ua dua tshiab thoob ntiaj teb. Peb tau muab ntau txhiab lub transformers rau cov haujlwm photovoltaic thiab khaws cia hluav taws xob thoob plaws North America, Europe, thiab Australia. Peb cov khoom tsis yog tsuas yog ua tau raws li cov qauv nruj xws li IEEE, ANSI, CSA, AN, IEC, thiab BS, tab sis kuj muaj daim ntawv pov thawj suav nrog UL, cUL, CSA, CE, SGS, thiab lwm yam, txhawb nqa los ntawm cov ntawv qhia kev xeem tiav.

Kev ua haujlwm tau zoo, kev ntseeg siab, thiab kev nyab xeeb yog cov hauv paus ntsiab lus tseem ceeb uas peb ua raws li.

Cov Kev Xav Tau ntawm SG250HX Transformer

1) Lub transformer yuav tsum tsim nyog rau kev ua haujlwm nrog lub pulsed inverter.

2) Yog tias siv cov tshuaj anti-PID (tej zaum yuav ua rau puas tsuaj), cov transformer secondary windings yuav tsum muaj peev xwm ua tau raws li Vrms = 906V VAC qhov siab tshaj plaws voltage siv rau hauv av rau 1500V system. Sab LV ntawm lub transformer thiab qhov siab tshaj plaws ntawm cov khoom siv tiv thaiv xob laim rau sab LV ntawm lub transformer yuav tsum ua raws li qhov yuav tsum tau ua no.

3) Lub zog hluav taws xob ntawm SG250HX yog 800Vac LL (640 ~ 920Vac), 50Hz lossis 60Hz. Lub zog hluav taws xob ntawm sab MV yuav tsum sib haum nrog lub zog hluav taws xob ntawm MV grid ntawm qhov chaw txuas, transformer nrog lub kais hloov pauv yog qhov zoo dua.

4) Lub peev xwm ntawm Transformer yuav tsum sib haum nrog lub zog tso zis siab tshaj plaws ntawm Inverters

5) Yuav tsum siv ob lub transformer sib cais (ob rau LV, ib qho rau MV sab), xav tau ob lub LV windings.

Cov kev sib txuas Dy11y11 siv tau. Yuav tsum siv lub transformer ob txoj hlua (ib txoj rau LV, ib txoj rau sab MV), xav tau ib txoj hlua LV, thiab siv tau cov kev sib txuas Dy11.

6) Impedance voltage Z(%) yuav tsum ua raws li cov qauv kev cai. Xws li IEC 60076 lossis IEEE C57.12.34 thiab C57.12.00.

7) Lub transformer yuav tsum muaj peev xwm tiv taus qee qib ntawm harmonic tam sim no, qhov siab tshaj plaws. tag nrho harmonic tam sim no yog 5% ntawm cov tam sim no tseem ceeb ntawm lub zog nominal.

8) Lub transformer yuav tsum tiv taus qee qib ntawm DC Cheebtsam, 0.5% ntawm cov tam sim no tseem ceeb ntawm lub zog nominal.

9) Lub transformer yuav tsum tiv taus qhov tsis sib npaug ntawm theem tshwj xeeb, 5% ntawm tam sim no ntawm lub zog nominal.

10) Lub LV winding ntawm MV transformer yuav tsum tiv taus qhov voltage gradient dU / dt txog li 500V / μs rau hauv av.

11) Kev tiv thaiv zoo thiab kev sib cais ntawm LV thiab MV windings.

12) Lub transformer yuav tsum tau grounded ntawm ib qho chaw xwb, thiab qhov grounding ntawm lub transformer yuav tsum ruaj ntseg.

13) Chav kawm rwb thaiv tsev yuav tsum yog tsawg kawg F rau Transformer Hom Qhuavs thiab A rau hom roj.

Chav kawm rwb thaiv tsev AEBFHNC

Qhov kub siab tshaj plaws (℃) 105 120 130 155 180 200 220

Kub nce ntawm winding (K) 60 75 80 100 125 135 150

14) Qhov hnyav uas tau ntsuas ua haujlwm tau zoo yuav tsum ua raws li cov kev cai hauv zos tshiab.

15) Yuav tsum xav txog qhov chaw ib puag ncig (kub, av noo, qhov siab, huab cua, thiab lwm yam).

16) Qhov kub nce thiab qhov tsawg kawg nkaus ntawm hluav taws xob yuav tsum tau xav txog tshwj xeeb tshaj yog thaum qhov siab tshaj 1000m.

17) Yuav tsum tau ua raws li qhov zaus thiab cov qauv ntawm lub teb chaws.
