Resin-insulated Dry-mtundu Transformer SCB18-2000/10

Dry transformer ndi mtundu wa thiransifoma yamphamvu yosiyana ndi thiransifoma yomizidwa ndi mafuta, thiransifoma yomizidwa ndi mafuta ndikugwiritsa ntchito mafuta osinthika pakutchinjiriza ndi kutulutsa kutentha, koma zida zotchinjiriza za thiransifoma wowuma nthawi zambiri zimakhala kutchinjiriza komwe kumapangidwa ndi epoxy resin kuthira.

(1) Kapangidwe kachitsulo. Pakatikati pachitsulo cha transformer youma ndi gawo la maginito, lomwe limapangidwa ndi magawo awiri: chitsulo chachitsulo ndi goli lachitsulo. Kumangirira kumayikidwa pachimake, ndipo goli limagwiritsidwa ntchito kutseka maginito onse. Mapangidwe a pachimake amatha kugawidwa m'magulu awiri: mtundu wapakati ndi mtundu wa zipolopolo. Pachimake chimadziwika ndi goli lachitsulo pamwamba ndi pansi pamapiringidzo, koma silimazungulira mbali yokhotakhota; Chigoba cha chipolopolo chimadziwika ndi goli lachitsulo lomwe limazungulira osati pamwamba ndi pansi pamphepete mwamapiringidzo, komanso mbali za mafunde. Chifukwa mapangidwe ake ndi osavuta, mawonekedwe omangika ndi kutchinjiriza nawonso ndiabwino, kotero zosintha zamphamvu zaku China zowuma zimagwiritsa ntchito pachimake, pokhapokha muzitsulo zina zapadera zowuma (monga thiransifoma ya ng'anjo yamagetsi) kugwiritsa ntchito chipolopolo pachimake.

(2) Chitsulo chachitsulo. Chifukwa pachimake chitsulo ndi maginito ozungulira owuma mtundu thiransifoma, zinthu zake zimafuna maginito permeability, ndipo kokha maginito permeability kungachititse kuti chitsulo kutaya chitsulo. Chifukwa chake, pachimake chachitsulo cha thiransifoma chowuma chimapangidwa ndi chitsulo cha silicon. Pali mitundu iwiri ya silicon zitsulo pepala: otentha adagulung'undisa ndi ozizira adagulung'undisa zitsulo pepala. Chifukwa chitsulo chozizira chozizira chimakhala ndi permeability yapamwamba komanso kutayika kwazing'ono pamene ikuyendetsa njira yozungulira, ntchito yake ndi yabwino kusiyana ndi pepala lachitsulo chotentha, ndipo zosinthira zouma zapakhomo zonse zimagwiritsa ntchito pepala lozizira lachitsulo la silicon. The makulidwe a zoweta ozizira adagulung'undisa zitsulo pepala ndi 0,35, 0,30, 0.27mm ndi zina zotero. Ngati pepala ndi wandiweyani, eddi panopa imfa ndi lalikulu, ndipo ngati pepala ndi woonda, koyezera lamination ndi laling'ono, chifukwa pamwamba pa silikoni zitsulo pepala ayenera yokutidwa ndi wosanjikiza utoto insulating kuti insulate pepala ku chidutswa chimodzi. kwa wina.

Mapiringidzo ndi gawo lozungulira la chosinthira chowuma, chomwe nthawi zambiri chimapangidwa ndi aluminiyamu wokutidwa ndi mapepala kapena waya wamkuwa wowotchedwa.

Malinga ndi makonzedwe osiyanasiyana a ma windings apamwamba ndi otsika, ma windings amatha kugawidwa kukhala concentric ndi rhomboid. Kwa ma concentric windings, kuti athandizire kutsekemera pakati pa mafunde ndi pachimake, mafunde otsika-voltage nthawi zambiri amaikidwa pafupi ndi chigawo chapakati: kwa ma windings osakanikirana. Kuti muchepetse mtunda wa kutchinjiriza, mafunde otsika-voltage nthawi zambiri amayikidwa pafupi ndi goli.

Zida zazikulu zotchingira mkati mwa thiransifoma youma ndi mafuta owuma a thiransifoma, makatoni otsekereza, pepala la chingwe, pepala lamalata ndi zina zotero.

Kuti apereke voteji khola, kulamulira mphamvu kuyenda kapena kusintha katundu kukana panopa, m'pofunika kusintha voteji wa thiransifoma youma. Pakali pano, njira ya voteji kusintha youma-mtundu thiransifoma ndi kukhazikitsa wapampopi mbali imodzi ya mapiringidzo kudula kapena kuonjezera mbali ya matembenuzidwe matembenuzidwe kusintha chiwerengero cha mokhota makhota, kuti tikwaniritse njira ya kusintha kwa voteji posintha chiŵerengero cha voteji. Dera lomwe mapiringidzo amakokedwa ndikuwongolera kuti aziwongolera magetsi amatchedwa dera lowongolera ma voltage; Chosinthira chomwe chimagwiritsidwa ntchito posintha popi kuti chiwongolere kupanikizika kumatchedwa tap switch. Kawirikawiri, sitepe yotsatira ndikujambula pompopi yoyenera pa mafunde apamwamba kwambiri. Izi ndichifukwa choti ma voliyumu okwera kwambiri nthawi zambiri amayikidwa panja, zomwe zimapangitsa kuti pampuyo ikhale yabwino, chachiwiri, mbali yamagetsi yamagetsi ndi yaying'ono, gawo lomwe likunyamula papampopi ndi chosinthira chapampopi ndi laling'ono, komanso kulumikizana mwachindunji ndi makinawo. switch ndizothekanso kupangidwa.

Kuwongolera voteji mbali yachiwiri ya thiransifoma yowuma popanda kukana katundu, ndipo mbali yoyamba imachotsedwanso ku gululi yamagetsi (palibe mphamvu yamagetsi), imatchedwa lamulo la voteji popanda kutengeka, ndi lamulo la voteji ndi kukana katundu kwa kutembenuka kugogoda.
