I. Isifinyezo Esijwayelekile Somkhiqizo
Uchungechunge lwe-SCB12, SCB14, kanye ne-SCB18 lwe-35kV luyiziguquli zamandla ezintathu ezigxile ezindaweni ezomile ezifakwe i-epoxy resin. Zinezici zenuzi yensimbi ye-silicon eqondiswe ku-grain enokungena okuphezulu kanye nezingqimba ezifakwe i-vacuum ezine-F/H grade insulation. Izici zenuzi zihlanganisa ukuvimbela umlilo okungenayo uwoyela, ukumelana nesekethe elifushane, ukukhishwa okuncane kwengxenye, ukonga amandla, nokungadingi ukugcinwa. Ziklanywe futhi zakhiqizwa ngokuqinile ngokuhambisana namazinga afana ne-GB 20052-2024 "Energy Efficiency Limits and Energy Efficiency Grades for Power Transformers", GB/T 1094, kanye ne-GB/T 22072. Zisetshenziswa ikakhulukazi ezindaweni zokusabalalisa zokugcina lapho amandla angu-35kV ehla ngqo aye ku-0.4kV. Lokhu kususa isidingo sesigaba esiphakathi sesiguquli samandla angu-10kV futhi kufaneleka eziteshini zamandla ezinkulu zasemadolobheni, izindawo ezinkulu zezimboni, izikhungo zedatha, izakhiwo eziphakeme, izitimela ezingaphansi komhlaba, izikhumulo zezindiza, kanye nezindawo ezibalulekile zasendlini ezinemibandela eqinile yokuvikela umlilo kanye nemvelo.
Incazelo Yemodeli: S = omathathu; C = ukubunjwa nge-epoxy resin; B = ukugoqwa kwe-foil yamandla aphansi; 12/14/18 = inombolo yokulandelana yomklamo wokusebenza (ihambisana namazinga okonga amandla).
Izinga Lamandla Kagesi: Amandla aphezulu angu-35kV, amandla aphansi angu-0.4kV (ejwayelekile), angalungiswa ukuze ahambisane namazinga amaningi kagesi angu-35/6/10kV.
Ububanzi bamandla: 500kVA kuya ku-25000kVA (okujwayelekile kusuka ku-800kVA kuya ku-10000kVA).
Ukuhlanganisa nokupholisa: Izinga elijwayelekile le-F (155℃), izinga le-H (180℃) elikhethwayo; izindlela zokupholisa i-AN (ukuzipholisa) / i-AF (ukupholisa ngomoya).
Izinga Lokuvikela: IP20 (ejwayelekile), i-IP30, i-IP54 (evikela uthuli nomswakama) ezikhethwayo.
Ukucushwa Okuyinhloko: Akukho ukulawulwa kwe-voltage ngaphandle kokuvuselela (±2×2.5%), kuhlomele ukulawula izinga lokushisa okuhlakaniphile, ukuxhumanisa ifeni, ukuxhumana kwe-RS485, nemisebenzi ye-alamu yokuphazamiseka.

II. Ukuqhathaniswa Kwezinto Eziyinhloko Zochungechunge (GB 20052-2024)
I-SCB12 imodeli yokusebenza kahle kwamandla ye-Class 3 (i-NX3), esebenza njengemodeli eyisisekelo yamamitha omoya omile angu-35kV. Inobuchwepheshe obuvuthiwe nozinzile, izindleko eziphansi, nokusebenza okuhlukahlukene. Ukulahleka okungenamthwalo nokulahleka komthwalo kuhlangabezana nezidingo eziphansi kakhulu ezijwayelekile zikazwelonke. Inhliziyo isebenzisa amashidi ensimbi ye-silicon esezingeni eliphezulu, inesakhiwo esihlangene futhi kulula ukuyifaka. Isetshenziswa ikakhulukazi ekulungisweni kwezindawo ezikhona, ukufakwa kwezinto ezindala, kanye nezakhiwo ezijwayelekile zezimboni nezomphakathi ezinemibhajethi elinganiselwe, efanele izimo ezinokushintshashintsha okuncane komthwalo kanye nesikhathi esiphakathi sokusebenza.

SCB14 iyimodeli ye-Class 2 yokusebenza kahle kwamandla (NX2), eyingxenye yemodeli yokonga amandla evamile emakethe. Ukulahleka kokung carga kwe-SCB14 kwehlelwa cishe ngo-15%, kanti ukulahleka kokucindezela kwehlelwa cishe ngo-10%. Isebenzisa amaphepha ensimbi ye-silicon enokuhamba okuphezulu kwe-magnetic conductivity kanye nokwakhiwa kwe-air duct okuhlelwe kahle, okuholela ekutheni kube nendawo encane, umsindo ophansi, kanye nokukhishwa kokushisa okuqinile. Ukusebenza kwezindleko kuphumelela kakhulu, kufanelekile ezimeni eziningi ezifana nezikhungo zokuhweba ezintsha, izibhedlela, izikole, imboni ephakathi, kanye neziteshi ezijwayelekile zasemadolobheni. Kuyikhethwa okuvamile kwemaphrojekthi amasha.

I-SCB18 imodeli ye-Class 1 yokonga amandla (i-NX1), emele izinga eliphezulu kakhulu lokonga amandla okuphelele kumathuluzi omile angu-35kV. Ukulahleka okungenamthwalo kwe-SCB18 kuncishiswe ngo-25% kuya ku-30% uma kuqhathaniswa ne-SCB12, futhi ukulahleka komthwalo kuncishiswe cishe ngo-12%. Isebenzisa amashidi ensimbi ye-silicon ye-Hi-B enokuhamba okuphezulu kakhulu kukagesi, izixhumanisi eziyisicaba eziningi eziyisicaba, kanye nobuchwepheshe bokulahleka okuphansi, ngokukhishwa kwendawo okungu-≤ 5pC, umsindo ongaphansi kuka-≤ 45dB, kanye nokusebenza okuhle kakhulu kokumelana nokushaqeka nokushaqeka. Ukutshalwa kwezimali kokuqala kuphezulu kakhulu, kodwa kunikeza ukonga ugesi okubalulekile minyaka yonke, futhi izindleko zingabuyiselwa phakathi neminyaka emi-3 kuya kwemi-5. Isetshenziswa ngokukhethekile kumalabhorethri edatha, izikhungo zenethiwekhi yamandla, izakhiwo eziphakeme kakhulu, iziteshi zamandla amasha, izindawo ezinamanani aphezulu kagesi, kanye namaphrojekthi abalulekile wokungathathi hlangothi kwekhabhoni esikhathini eside esigcwele.

III. Ubuchwepheshe Obubalulekile Nezici Zesakhiwo

2. Ama-Windings: Uhlobo lwe-foil oluphansi, uhlobo lwe-wire winding / foil oluphakeme, ukusakazwa kwe-epoxy resin nge-vacuum pressure, nokuvuselelwa nge-glass fiber ngaphakathi nangaphandle. Kunamandla omshini aphezulu, amandla aqinile okuvimbela ukushintshana okufushane, ukumelana nomswakama, ukumelana nothuli, akukho ukuqhekeka, nokukhishwa okuncane kakhulu kwengxenye.
3. Ukuphepha Nokuvikelwa Kwemvelo: Akukho mafuta, ukuvimbela umlilo, ukuzishisa okuzimele, akukho gazi eliyingozi ngesikhathi sokushiswa. Kungafakwa ngqo endaweni yokulayisha, akukho ukugcinwa, akukho ukungcoliswa, isikhathi sokuphila esingaphezu kweminyaka engu-30.
4. Ukukhishwa Kwamazinga Okushisa Nokulawula Izinga Lokushisa: Umgudu wokuhambisa umoya + ukupholisa komoya okwenziwayo (AF), enekhono eliqinile lokulayisha; ifakwe i-PT100 yokukala izinga lokushisa kanye nomlawuli wezinga lokushisa ohlakaniphile, ifinyelela esixwayisweni sokushisa esiphezulu, ukuqala-n停止 kwefan ngokuzenzakalelayo nokubhekwa kude.
5. Ukusebenza Kokuvikela Ugesi: Ukuvikela okuyinhloko kwezinga elingu-35kV kanye nomklamo wokuvikela ovundlile, okumelana nokushaywa umbani, okuhlangabezana namazinga okumelana namandla kagesi omjikelezo ojwayelekile, okufanelekayo ezindaweni ezinzima njengomswakama, uthuli, nenkungu kasawoti.

IV. Izinzuzo Eziyinhloko Zokuphakama Kwe-voltage Okungu-35kV
Yenza lula inethiwekhi yamandla: Yehla ngqo kusuka ku-35kV kuye ku-0.4kV, kunciphisa isidingo seziteshi zamandla ezingama-10kV, futhi kunciphisa ukutshalwa kwezimali, ukulahleka komugqa, kanye nezindleko zokusebenza nokugcinwa.
Umthamo omkhulu: Umthamo omkhulu womshini owodwa ungama-25,000 kVA, ulungele izindawo ezinkulu ezinomthwalo omkhulu kanye nokuhlinzekwa kwamandla kwemishini enamandla aphezulu.
Ukuthembeka okuphezulu: Uhlelo lwe-35kV lunokuzinza okungcono kune-10kV, lufanele abasebenzisi ababalulekile nezimo eziyinhloko zokusabalalisa amandla.
Igcina indawo kakhulu: Uma iqhathaniswa nama-transformer agxiliswe uwoyela, inevolumu encane, isisindo esilula, ayidingi amabanga okwahlukanisa umlilo noma amachibi kawoyela, futhi ilungele izindawo zangaphakathi, ezingaphansi komhlaba, nezindawo ezinomkhawulo wesikhala.
