Mu ma transfoma othamanga kwambiri, zotsatira zake zidzakhala zotani ngati mtengo wa inductance upitilira mulingo womwe waperekedwa?

 

Transformer yapamwamba kwambirindi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kutembenuza magetsi ndi magetsi. Amagwiritsidwa ntchito polumikizira opanda zingwe, kutembenuza mphamvu, ndizida zamagetsi. Muma transfoma apamwamba kwambiri, kusankha ndi kulamulira kwa inductance n'kofunika kwambiri chifukwa kudzakhudza mwachindunji ntchito ndi kukhazikika kwa transformer. Ngati inductance ipitilira muyeso womwe wapatsidwa, zotsatirazi zitha kuchitika:

1. Magnetic core saturation: Muma transfoma apamwamba kwambiri, iron cores kapena maginito zipangizo nthawi zambiri ntchito kuonjezerainductance. Pamene inductance idutsa muyeso wina, pachimake chikhoza kukhala chodzaza. Machulukidwe apakati amayambitsa kuchulukirachulukira kwa flux, komwe kumabweretsa kusakhazikika komanso kupotoza kwa inductor. Izi zingayambitse kusakhazikika komanso kusokonezeka kwa harmonic mu mphamvu yamagetsi.

2. Kuwonongeka kwakukulu: Pachimake ndi koyilo mkati mwa inductor zidzatulutsa zotayika zina, nthawi zambiri monga kutayika kwa mkuwa ndi kutayika kwachitsulo. Pamene inductance ikukwera kwambiri, panopa mu koyiloyo imakhala yaikulu, zomwe zimapangitsa kuti ziwonongeke zamkuwa. Kuphatikiza apo, kuchulukitsidwa kwapakati kudzatsogoleranso kuwonjezereka kwa kutayika kwachitsulo. Izi zitha kukhalahigh frequency transformerosagwira bwino ntchito.

3. Vuto la kutentha: Kuwonongeka kowonjezereka kumapangitsanso kuti transformer itenthe kwambiri. Ngati sichikuzizira bwino kapena ndi kutentha kosakwanira, izi zingayambitse kutentha, ndipo pamapeto pake zimakhudza moyo ndi kudalirika kwa transformer yothamanga kwambiri.

4. Kuvuta kwa Malamulo: Muzogwiritsira ntchito maulendo apamwamba, zowona zenizeni za inductance nthawi zambiri zimafunika kuti zitsimikizire kuti transformer idzagwira ntchito mkati mwazomwe zimapangidwira. Ngati mtengo wa inductance umaposa zomwe zaperekedwa, kusintha kumakhala kovuta kwambiri ndipo transformer ingafunikire kukonzanso.

5. Nkhani za Harmonic: Magwiridwe a ma harmonic a ma transformer apamwamba kwambiri ndi ofunika kwambiri pazinthu zina, monga machitidwe oyankhulana opanda zingwe. Kusankhidwa kolakwika kwa mtengo wa inductor kungayambitse kusokoneza kwa harmonic, kukhudza khalidwe la kulankhulana.

Kupewa mavutowa, kusankhainductormtengo uyenera kuganiziridwa mosamala popanga ma transfoma apamwamba kwambiri ndikuwonetsetsa kuti ili mkati mwa mapangidwe. Nthawi zambiri, kusankha kwa mtengo wa inductor kumakhudzidwa ndi zinthu monga zofunikira za kapangidwe kake, ma frequency ogwiritsira ntchito, magetsi olowera, ndi magetsi otulutsa. M'mapangidwe enieni, kuyerekezera dera ndi kutsimikizira koyesera nthawi zambiri kumafunika kuonetsetsa kuti kusankhidwa kwa mtengo wa inductor ndi koyenera ndipo kumatha kukwaniritsa ntchito ndi kukhazikika.

Pamafunso azinthu, chonde onanitsamba mankhwala, nanunso mwalandiridwaLumikizanani nafekudzera muzomwe zili pansipa, tidzakuyankhani mkati mwa 24.
