Isisombululo seNkqubo yeSolar Photovoltaic

I-JZP Transformer yinkokheli yehlabathi ekukhonzeni icandelo lamandla avuselelekayo kwihlabathi liphela. Ngerekhodi eqinisekisiweyo, sinikezele ngamawaka ee-transformers kwiiprojekthi zokugcina i-photovoltaic kunye namandla kulo lonke elaseMntla Melika, eYurophu nase-Australia. Iimveliso zethu azihlangabezani nje kuphela nemigangatho engqongqo efana ne-IEEE, ANSI, CSA, AN, IEC, kunye ne-BS, kodwa zikwanazo neziqinisekiso eziquka i-UL, cUL, CSA, CE, SGS, kunye nezinye, ezixhaswa ziingxelo zovavanyo ezipheleleyo.

Ukusebenza kakuhle, ukuthembeka, kunye nokhuseleko zizinto ezisisiseko esizinamathela ngokungagungqiyo.

Iimfuno zeTransformer ye-SG250HX

1) I-transformer kufuneka ilungele ukusebenza nge-inverter eshukumayo.

2) Ukuba kusetyenziswa isisombululo esichasene ne-PID (ukonakala okubangelwa kukubola okunokwenzeka), ii-windings zesibini ze-transformer ziya kukwazi ukuphatha i-Vrms=906V VAC peak voltage reference emhlabeni kwinkqubo ye-1500V. Icala le-LV le-transformer kunye ne-voltage ephezulu eqhubekayo yezixhobo zokukhusela umbane kwicala le-LV le-transformer kufuneka zihambelane nale mfuneko.

3) I-voltage yokuphuma ye-SG250HX yi-800Vac LL (640~920Vac), 50Hz okanye 60Hz. I-voltage ecaleni kwe-MV mayihambelane ne-voltage yegridi ye-MV kwindawo yokudibanisa, i-transformer ene-tap changer iyakhethwa.

4) Umthamo wetransformer kufuneka uhambelane namandla aphezulu e-Inverters output

5) Kufuneka kusetyenziswe itransformer ephindwe kabini (ezimbini ze-LV, enye yecala le-MV), kufuneka ii-windings ezimbini ze-LV.

Kungasetyenziswa uqhagamshelo lweDy11y11. Kufuneka kusetyenziswe itransformer ephindwe kabini (enye yeLV, enye yeMV) ukuze kusetyenziswe uqhagamshelo lweLV, kufuneka uqhagamshelo lweLV olunye, kwaye kusetyenziswe uqhagamshelo lweDy11.

6) I-impedance voltage Z(%) kufuneka ihambelane neemfuno ezisemgangathweni ezinxulumeneyo. Ezifana ne-IEC 60076 okanye i-IEEE C57.12.34 kunye ne-C57.12.00.

7) I-transformer kufuneka ikwazi ukumelana nenqanaba elithile lomsinga we-harmonic, umsinga we-harmonic ophezulu yi-5% yomsinga osisiseko kumandla aqhelekileyo.

8) I-transformer kufuneka imelane nenqanaba elithile le-DC component, i-0.5% yamandla asisiseko kumandla aqhelekileyo.

9) I-transformer kufuneka imelane nokungalingani kwesigaba esithile, i-5% yamandla angoku kumandla aqhelekileyo.

10) Ukujija kwe-LV kwe-MV transformer kufuneka kumelane ne-voltage gradient dU/dt ukuya kuthi ga kwi-500V/μs emhlabeni.

11) Ikhaka elihle kunye nokwahlulwa phakathi kwee-LV kunye nee-MV windings.

12) I-transformer mayisekelwe kwindawo enye kuphela, kwaye isiseko se-transformer kufuneka siqine.

13) Udidi lobushushu kufuneka lube ngu-F ubuncinane Isiguquli sohlobo olomileyou-s kunye no-A bohlobo lweoyile.

Iklasi yokwambathisa i-AEBFHNC

Ubushushu obuphezulu (℃) 105 120 130 155 180 200 220

Ukuphakama kobushushu bokujika (K) 60 75 80 100 125 135 150

14) Ukusebenza kakuhle komthwalo olinganisiweyo kufuneka kuhambelane neemfuno zamva nje zasekuhlaleni.

15) Imeko-bume yendawo (ubushushu, ukufuma, ukuphakama, umoya, njl.njl.) mayiqwalaselwe.

16) Ukunyuka kwamaqondo obushushu kunye nokususwa kombane okuncinci kuya kuqwalaselwa ngakumbi xa ukuphakama kungaphezulu kwe-1000m.

17) Imigangatho kunye nemigangatho yegridi yelizwe elithile mayihlonitshwe.
