Tharollo ea Sistimi ea Photovoltaic ea Letsatsi

JZP Transformer ke moetapele oa lefats'e ho sebeletseng lekala la eneji e nchafatsoang lefatšeng ka bophara. Ka rekoto e pakiloeng, re fane ka li-transformer tse likete bakeng sa merero ea photovoltaic le polokelo ea matla ho pholletsa le Amerika Leboea, Europe le Australia. Lihlahisoa tsa rona ha li fihlelle feela litekanyetso tse thata joalo ka IEEE, ANSI, CSA, AN, IEC, le BS, empa hape li na le mangolo a netefatso ho kenyeletsoa UL, cUL, CSA, CE, SGS, le tse ling, tse tšehetsoang ke litlaleho tse felletseng tsa liteko.

Litlhoko tsa Transformer ea SG250HX

1) Transformer e lokela ho ba e loketseng ho sebetsa ka inverter e pulsed.

2) Haeba ho sebelisoa tharollo e khahlanong le PID (ho senyeha ho ka bakoang ke ho senyeha ho ka bang teng), li-winding tsa bobeli tsa transformer li tla khona ho sebetsana le Vrms=906V VAC peak voltage reference ho ea mobung bakeng sa sistimi ea 1500V. Lehlakore la LV la transformer le motlakase o phahameng ka ho fetisisa o tsoelang pele oa lisebelisoa tsa tšireletso ea lehalima bakeng sa lehlakore la LV la transformer li lokela ho latela tlhoko ena.

3) Motlakase o tswang wa SG250HX ke 800Vac LL (640~920Vac), 50Hz kapa 60Hz. Motlakase o lehlakoreng la MV o tla tsamaellana le motlakase wa gridi ya MV sebakeng sa kgokelo, transformer e nang le pompo e fetolang e a kgethwa.

4) Bokgoni ba transformer bo lokela ho tsamaellana le matla a tlhahiso a phahameng ka ho fetisisa a Inverters

5) Ho tla sebelisoa transformer e arohaneng habeli (tse peli bakeng sa LV, e 'ngoe bakeng sa lehlakore la MV), ho hlokahala li-winding tse peli tsa LV.

Likhokahano tsa Dy11y11 li ka sebelisoa. Transformer e kobehang habeli (e 'ngoe bakeng sa LV, e 'ngoe bakeng sa lehlakore la MV) e lokela ho sebelisoa, ho kobeha ho le leng ha LV hoa hlokahala, 'me likhokahano tsa Dy11 li ka sebelisoa.

6) Voltage ea Impedance Z(%) e tla latela litlhoko tse tloaelehileng tse amanang le eona. Tse kang IEC 60076 kapa IEEE C57.12.34 le C57.12.00.

7) Transformer e tla kgona ho mamella boemo bo itseng ba hona joale ya harmonic, palo yohle ya hona jwale ya harmonic ke 5% ya hona jwale ya motheo ka matla a nominee.

8) Transformer e tla mamella boemo bo itseng ba karolo ea DC, 0.5% ea motlakase oa motheo ka matla a tloaelehileng.

9) Transformer e tla mamella ho se leka-lekane ho itseng ha mokhahlelo, 5% ea hona joale ka matla a tloaelehileng.

10) Ho kobeha ha LV ha transformer ea MV ho tla mamella gradient ea voltage dU/dt e fihlang ho 500V/μs ho ea fatše.

11) Thebe e ntle le karohano pakeng tsa mapheo a LV le MV.

12) Transformer e lokela ho thewa sebakeng se le seng feela, mme motheo wa transformer o lokela ho tiya.

13) Sehlopha sa ho thibela ho futhumala e lokela ho ba bonyane F bakeng sa Transformer ea Mofuta o Omilengs le A bakeng sa mofuta oa oli.

Sehlopha sa ho kenya thepa ka hare AEBFHNC

Mocheso o phahameng ka ho fetisisa (℃) 105 120 130 155 180 200 220

Ho phahamisa mocheso oa ho phethoha (K) 60 75 80 100 125 135 150

14) Bokgoni ba ho lekanya mojaro bo lokela ho latela ditlhoko tsa moraorao tsa lehae.

15) Tikoloho ea sebaka seo (mocheso, mongobo, bophahamo, moea, jj.) e lokela ho nahanoa.

16) Ho phahama ha mocheso le ho tlosoa ha motlakase ho tla nahaneloa haholoholo ha bophahamo bo feta 1000m.

17) Maqhubu le maemo a gridi a naha ka ho khetheha a tla hlomphuoa.
