II. Ukwakheka Komqulu
1. Inhliziyo
I-core yenziwe ngama-sheetensimbi e-silicon aqinile, aqondiswe ngokusanhla, aqinile. Inezindawo ezigcwele zokugoba, akukho zimbobo zokubopha, kanye nezingqimba eziningi, okwenza ukulahleka okuphansi, umsindo ophansi, kanye nomfutho ophansi wokuvuselela.
2. Imisongelo
Ama-windings aphezulu kakhulu asebenzisa uhlobo olulukiwe kanye nesakhiwo esiqhubekayo sokuvikela sangaphakathi;
Izintambo eziphakathi nezishintshayo zisebenzisa uhlobo oluyisipikili noma oluqhubekayo;
Ukusetshenziswa kwezintambo ezihlukene kuqinisekisa ukucindezela okuphelele okuqinile kanye nekhono eliqinile lokumelana nokushintsha okufushane.
3. Ithangi lamafutha
Ikakhulu izimbiza zikawoyela ezimile okwezinsimbi, ezinamandla aphezulu futhi zilula ukuphakamisa nokuhlola imbiza;
Isakhiwo esivalekile sonke sivimbela ngempumelelo ukuvuza kwamafutha nokumunca umswakama.
4. Izesekeli eziyinhloko
I-bushing ephezulu engu-220kV, i-bushing ephakathi nephansi engu-110kV/35kV
I-reservoir kawoyela (umcamelo kawoyela), isikhwama / isicindezeli
Uhlelo lokuphehla amafutha oluphusha ngamandla + ifeni
On-load tap changer kanye nomshini kagesi
I-relay yegesi, ivolovula lokukhulula ingcindezi
I-gauge yokushisa kukagwayela / yokushisa kwezintambo, i-gauge yomkhawulo kawoyela, i-desiccant
Ingafakwa idivayisi yokuqapha i-online oil chromatography

III. Izici Zomkhiqizo
1. Ukuthembeka okuphezulu kokuvikela
Kusetshenziswa uhlelo lokuhlanganisa uwoyela-iphepha, ngokujova kwe-vacuum nokwelashwa komjikelezo wamafutha ashisa kakhulu, ukukhishwa kwengxenye kungaphansi futhi ukusebenza kokuhlanganisa kuzinzile.
2. Ukulahleka okuphansi, ukonga amandla
Kuhambisana namazinga kazwelonke wokonga amandla, ngokulahlekelwa okuncane okungenamthwalo nokomthwalo, ukusebenza kwesikhathi eside kunemiklomelo emikhulu yezenotho.
3. Ukumelana Namandla Okufushane Komjikelezo
Ukusekelwa okugoqayo kuqinile, futhi ukucindezelwa kwe-axial ne-radial kuthembekile, okwazi ukumelana nokushaqeka okungazelelwe okufushane emgqeni.
4. Ukusebenza Okuphephile Nokuzinzile
Ukulungiselelwa okuphelele kokuvikela kungafinyelela izivikelo eziningi ezifana nokushisa ngokweqile, igesi elikhanyayo, igesi elinzima, nokukhululwa kwengcindezi.
5. Ukuzivumelanisa Nemvelo Yangaphandle
Ingasebenza ngaphandle isikhathi eside, ikwazi ukumelana nezimo ezinzima njengokushisa okuphezulu nokuphansi, iziphepho zesihlabathi, imvula, neqhwa.
