25 kVA-333 kVA Isilungu sesikhathi esinye sokuthi sithunywa emhlabeni

U-DINGXIN uyavuka izinhlobo zonke amatransformer esilinganiso sesilinganiso ezifana nezinhlobo zokuthunywa kwezindawo zokuthunywa ngaphandle kwemithwana. Lezi zinhlobo zokuthunywa ziyathunywa ukusuka kwezinhlobo zokuthunywa ezinamandla kakhulu ukuze zibe yizinhlobo zokusebenza ezinamandla ema-ndaweni okusebenza, okusebenza kwezindawo zokusebenza, okusebenza kwezindawo zokulima, nokusebenza kwezindawo zokusebenza okuncane.

Kufakwa ngqo kumkhosi wokusebenza, le zinhlobo zokuthunywa azikho indawo yokusebenza yazo noma isikhundla sokufaka ngaphansi kwemali, futhi ukubeka kwazo okuncane kuyasinda ukusetshenziswa kwemali, ukusebenza kwemali, nokufakwa kwazo, okuyenza kube yisibonelo esihle kakhulu kwezindawo zokuthunywa ngaphandle kwemithwana kwezindawo zokusebenza nezindawo zokulima.

Izinhlobo zokuthunywa zokufakwa kumkhosi wokusebenza zika-DINGXIN zikhona kwi-tshiphi tshithe thuluzi:

• Ithayiphi yezinye: iyafakelwa ngezindlela zokuvikela zokuthunywa zokusebenza okuncane ukuze kuhlanganise nezindlela zokuvikela eziphakathi kwemithwana yokusebenza;
• Ithayiphi yezinye Yonke Yokuvikela—CSP: kufunekwe ngamathuba okulungisa okwesibonelo njenge-fuse yokuqala, isikhombisa sokuphakamisa kanye ne-circuit breaker yokuqala, kusukela kubekiwe kwisayensi esivumelwe;
• Uhlobo lwesikhombisa sokuphakamisa: kufunekwe ngamathuba okulungisa okwesibonelo kusuka kumkhosi wokuphakamisa kwekuqala ukuze kuzamele izinkinga zokulungisa kwe-distribution zomthengi.

Izinhambetho zesithembiso sezindawo zokusebenza ziyaphila kusukela ku- 10 kVA ku-250 kVA . Izinhambetho ezinye, kusukela kuma-unit eziyaphila ku-333 kVA, kungazamelekwa emva kokubhekwa kwemfundo yezinto eziningi njengezindawo zokuphakama kwe-pole, ubunzima bwe-transformer, i-voltage, amasimbi, kanye nezinkinga zokufaka.

I-voltage yokuqala, i-voltage yokwesibili, imithombo yewinding, imithombo yewebhu, iliquido lokulungisa, isistimu yokulungisa kanye nokuhlukaniswa kokufaka kungashintshwa.

U-Dingxin uyaweka umda ogcwele wezisilindi zokuguqula fomu elilodwa. I-transformers ezisilindi zikhona njengezifanekiso (5-167kVA), ziyimpela (CSP 5-75kVA), noma izibophezela (5-167kVA) kwiindlela ezahlukene ukwanelisa noma ukuphumelela kwiindlela eziphathelene ne-ANSI® neNEMA®. Iindlela ezinhlelwe ngokwemigaqo ye-Rural Utilities Service (RUS) zikhona nazo.

Izitransformer ze-CSP zinezinkwele zokugcinwa zokwesibili, izithuthi zokulandelana nezifuse zokugcinwa kwezinhloso. Lokhu kuthula inkinobodla yokuthenga izinkwele zokugcinwa ngokwesibonelo futhi kunciphisa izindleko zokufaka.

Ukubeka kwe-pole okuphezulu kakhulu

I-transformer ifakwa ngokudlula kwe-pole yomthengi futhi ayikhiphi indawo eyodwa yendawo yokuqondisa. Ayikho inkundla yomthengi yokuqondisa noma isiqondiso sesithembiso sokufaka kuyadingeka ngokujulile, okusiza ukunciphisa izindlela zokubhala kanye nokufaka.

Ukusebenza ngokusebenzayo kwekhono

Amaphakathi amagnethi nezinkamba ziyadesigniwa ukukhokha izinkinga zokusebenza ngaphandle kokusebenza nokusebenza. Izinketho zihlanganisa iphakathi le-CRGO yomthwalo wesiSilicon-steel okanye iphakathi le-amorphous-alloy kubizo obuyisisekelo labo abadinga izinkinga zokusebenza ngaphandle kokusebenza eziphansi kakhulu.

Izinhlobo zokusebenza ngokuphelele zingadesigniwa ngokwesikhundla sesiprojekthi esiyisisekelo. Kufanele kubonakaliswe ukuthi isithuthi siphatha ngokuphelele kwezimali zaseNingizimu Afrika kusithuthi esithile, isilinganiso, nokumakheti.

Ukuvikela phandle kwemvumo yamazulu

Isitanki esisilayiwa kusiza ukuvikela ukuvikela kwezindawo zokusebenza zokugcina phakathi kwamazulu, amandla, nokungena komnye umnyango. Isistimu sokuchitha singakhethwa ngokwesikhundla sokufaka, kuhlanganisa ukuchitha okuzenzakaleyo phakathi kwemini noma ukuchitha okujulile kwezinyo zokuvikela kwezinyo.

Izinketho Zokuguqula Ivolthi Nezinhlobo

UDINGXIN uyavikela izinhlobo eziningi zezivolthi zokuphambuka nezokuphambuka, izinhlobo, izifrequensi, izitapu, nezindlela zokugcina. Izithuthi zesivoli zokuphambuka noma zokuphambuka okuhlanganisa okuhlelwa ngokwezinyo zingatholakala emva kokuhlola kwe-engineering.

Ukuvikela Okungafani

Kukhetha izinkambo zokulinda kwe-CSP, izinkambo zokulinda zingakwenzelwa ngqo kule-transformer noma kusuka kumandla wakhe. Lokhu kungahlela ukuthi kuzofanele ukubeka izinkambo ezithile eziphakanyiswe ngokwezinye, ukuphazamisa ukubeka amandla emkhosi, nokunciphisa izindlela zokufaka.

Izidingo Zokunakekelwa Okuphansi

Ukubekwa kwemvelo yokugcina, isibonelo sokulindela ukuchitha, nokusebenza kwezinto ezinamandla kusuka kumandla wokuphuma kuzosula ukuthi kuzofanele ukwenza izinyathelo zokulinda ngokuphakeme, nokuhambisa ukusebenza kwezindawo zokuphuma ngokudlula.

Ukufaka Ngokuthe ngokushesha

Izitransformer ezibekwe kumthambo zingafakwa, zingashaniswa noma zingabuyiselwa ngokushesha kunamanye amandla okusakaza ekhaya. Lokhu kuzosula ukuthi ziyisisekelo sokunika amandla okusebenza ngokuthemporary, amandla okusebenza ngokwesihlanu, nokuthuthukisa ngokushesha amandla okusakaza.
