Gawo nambala kusiyanitsa

Itha kugawidwa m'magawo atatu osinthira ndi gawo limodzi.Mu magawo atatu mphamvu dongosolo, ambiri ntchito atatu-gawo thiransifoma, pamene mphamvu ndi lalikulu kwambiri ndi zoletsedwa ndi zinthu zoyendera, mu magawo atatu mphamvu dongosolo angagwiritsidwenso ntchito atatu gawo limodzi thiransifoma zikuchokera thiransifoma gulu.

Kuthamanga kusiyanitsa

Zitha kugawidwa muwiri wokhotakhota thiransifoma ndi atatu okhotakhota thiransifoma.Nthawi zambiri thiransifoma ndi ma thiransifoma oyenda pawiri, ndiko kuti, pali ma windings awiri pachimake chitsulo, chimodzi ndi choyambirira, chimodzi ndi chachiwiri.Ma thiransifoma oyenda katatu ndi ma transfoma akulu akulu (pamwamba pa 5600 kVA) omwe amagwiritsidwa ntchito kulumikiza mizere itatu yotumizira ma voltage.Muzochitika zapadera, palinso ma Transformers a Saton omwe amagwiritsa ntchito ma windings ambiri.

Magulu a kamangidwe

Itha kugawidwa kukhala chitsulo-pachimake thiransifoma ndi chitsulo-chipolopolo thiransifoma.Ngati phukusi lokhotakhota pamphepete mwapakati ndi chosinthira chamtundu wapakatikati;Ngati chitsulo chapakati chazunguliridwa mozungulira pozungulirapo, chimakhala chosinthira chachitsulo.Awiriwo ndi osiyana pang'ono mu kapangidwe, koma palibe kusiyana kofunikira pa mfundo.Magetsi osinthira mphamvu ndi amtundu wapakati.

Transformer imapangidwa makamaka ndi chitsulo chachitsulo, mapindikidwe, thanki yamafuta, pilo yamafuta, chitsamba chotsekereza, chosinthira chapampopi ndi kutumizirana gasi.

Chitsulo chachitsulo

Chitsulo chachitsulo ndi gawo la maginito a transformer. Hysteresis imfa ndi kuwonongeka kwa eddy panopa kumapangidwa panthawi yogwira ntchito. conductivity zosakwana 0.35mm. Malinga ndi dongosolo la mapiringidzo pachimake, pali pachimake mtundu ndi chipolopolo mtundu.

Mu thiransifoma wa mphamvu yaikulu, kuti kutentha kwaiye chifukwa imfa ya chitsulo pachimake akhoza kwathunthu kuchotsedwa ndi insulating mafuta pa mkombero, kuti tikwaniritse kuzirala kwenikweni, kuzirala mafuta njira nthawi zambiri amapereka mu pachimake chitsulo.

Kumazungulira

Mapiringidzo ndi chitsulo pakati ndi zigawo zikuluzikulu za transformer.Chifukwa chakuti pali kutsutsa mu mphepo yokhayokha kapena kukaniza kukhudzana ndi mgwirizano, kutentha kumayenera kupangidwa ndi lamulo la Joule.Chotero, kupukuta sikungathe kudutsa panopa kuposa momwe akuyembekezeredwa kwa nthawi yaitali.Kuonjezera apo, mphamvu yachidule yamagetsi idzatulutsa mphamvu yaikulu yamagetsi pamagetsi ndikuwononga transformer.

Zolakwa zazikulu za thiransifoma windings ndi dera lalifupi pakati pa kutembenuka ndi dera lalifupi kwa chipolopolo.Interturn yochepa dera makamaka chifukwa cha kutchinjiriza kukalamba, kapena chifukwa cha thiransifoma zimamuchulukira ndi kudzera yochepa dera kutchinjiriza ndi kuwonongeka makina.Mafuta pamwamba pa thiransifoma akutsikira, kotero kuti mapiringidzo amawonekera pamwamba pa mafuta, kusinthasintha kwafupipafupi kungathenso kuchitika; Kuonjezerapo, pamene mukudutsa dera lalifupi, chifukwa cha kuwonjezereka kwaposachedwa kwa mapindidwe opindika, kotero kuti kutchinjiriza ndi kuwonongeka kwa mawotchi, komanso kutulutsa kozungulira kozungulira.Pankhani ya interturn short circuit, yomwe ili mumayendedwe afupiafupi imatha kupitirira mtengo wovotera, koma panopa pamapiritsi onse sangapitirire mtengo wovotera.Pachifukwa ichi, chitetezo cha gasi, vuto lalikulu, chipangizo chotetezera chosiyana chidzakhalanso chikugwira ntchito. Chifukwa chafupikitsa cha chipolopolocho chimakhalanso chifukwa cha kukalamba kapena kunyowa kwa mafuta, kutsika kwa mafuta, kapena chifukwa cha mphezi ndi ntchito overvoltage.Kuonjezera apo, pamene mukudutsa mufupipafupi, kupukuta kumakhala kopunduka chifukwa cha kupitirira apo, ndipo chochitika chachifupi chidzachitikanso ku chipolopolo.Pamene chipolopolocho chimakhala chachifupi, nthawi zambiri chimakhala choteteza mpweya komanso chitetezo chapansi.

Tanki yamafuta

Thupi (lozungulira ndi chitsulo) la chosinthira chomizidwa ndi mafuta limayikidwa mu thanki yamafuta yodzaza ndi mafuta osinthira, ndipo thanki yamafuta imawotchedwa ndi mbale zachitsulo.Tanki yamafuta ya thiransifoma yapakatikati ndi yaying'ono imapangidwa ndi chipolopolo cha bokosi ndi chivundikiro cha bokosi.Thupi la transformer limayikidwa mu chipolopolo cha bokosi.Chophimba cha bokosi chikhoza kutsegulidwa kuti chitulutsidwe kunja kwa thupi kuti chisamalidwe.

Kachitidwe kosintha mawu

A. Kuphatikiza pa waya wamkuwa wocheperako, mafunde otsika kwambiri a thiransifoma yomizidwa ndi mafuta nthawi zambiri amatengera mawonekedwe a silinda a zojambula zamkuwa kuzungulira tsinde;Mapiritsi amphamvu kwambiri amatengera mawonekedwe a silinda angapo, kotero kuti kugawa kwa ampere-kutembenukira kumakhala koyenera, kutulutsa kwa maginito kumakhala kochepa, mphamvu yamakina ndi yayikulu, ndipo kukana kwafupipafupi kumakhala kolimba.

B. Njira zomangirira zimatengera pachimake ndi mapindikidwe motsatana.Zigawo zomangirira monga kutalika kwa chipangizocho ndi waya wotsogola otsika-voltage zonse zili ndi mtedza wodzitsekera woletsa kumasula, ndipo kapangidwe kake popanda kukweza pachimake amatengedwa kuti athe kupirira kugwedezeka kwamayendedwe.

C. Koyilo ndi pachimake pogwiritsa ntchito vacuum kuyanika, thiransifoma mafuta ntchito zingalowe mafuta fyuluta ndi mafuta jekeseni ndondomeko, kuti thiransifoma chinyezi mkati osachepera.

D. Tanki yamafuta imatenga pepala lamalata, lomwe lili ndi ntchito yopuma kuti lipereke malipiro a kusintha kwa mafuta chifukwa cha kusintha kwa kutentha, kotero kuti mankhwalawa alibe thanki yosungiramo mafuta, zomwe mwachiwonekere zimachepetsa kutalika kwa thiransifoma.

E. Chifukwa pepala lamalata linalowa m'malo mwa thanki yosungiramo mafuta, mafuta a thiransifoma amasiyanitsidwa ndi dziko lakunja, kuti ateteze bwino kulowa kwa mpweya ndi madzi ndikupangitsa kuchepa kwa ntchito yotsekera.

F. Malingana ndi mfundo zisanu zomwe zili pamwambazi, thiransifoma yomizidwa ndi mafuta sichifunikira kusintha mafuta pakugwira ntchito bwino, zomwe zimachepetsa kwambiri mtengo wokonza thiransifoma ndikuwonjezera moyo wautumiki wa transformer.
