Kuyang'ana koyamba kwa ma frequency osintha kwambiri, mawu oyamba a mfundo ya thiransifoma

1, Chiyambi cha mfundo ya thiransifoma

Transformer monga dzina limatanthawuzira, sinthani voteji ya zida zamagetsi zamagetsi.Ndiko kugwiritsa ntchito mfundo ya Faraday electromagnetic induction posintha chipangizo chamagetsi cha AC, makamaka ndi koyilo yoyambira, pachimake chachitsulo, koyilo yachiwiri ndi zida zina.Iwo akhoza kukwaniritsa athandizira ndi linanena bungwe panopa, voteji ndi impedance yofananira kutembenuka, etc. Iwo akhoza kukwaniritsa kudzipatula thupi la pulayimale siteji.Malinga ndi ma voltage osiyanasiyana a gawo loyambira, imatha kugawidwa kukhala chosinthira chotsika, chosinthira chokwera, chosinthira chodzipatula, ndi zina zambiri.

2, Malinga ndi ma frequency osiyanasiyana ogwirira ntchito, amagawidwa kukhala otsika pafupipafupi thiransifoma ndi otsika pafupipafupi thiransifoma.

Mafupipafupi amagetsi opanga moyo wathu watsiku ndi tsiku ndi 50 Hz, timatcha mphamvu iyi ya AC otsika ma frequency AC mphamvu.Ngati thiransifoma imagwira ntchito pafupipafupi, timapanga thiransifoma iyi kukhala yotsika kwambiri, yomwe imatchedwanso mafakitale frequency transformer.Mtundu uwu wa thiransifoma ndi waukulu komanso wosagwira ntchito bwino, pachimakecho amapangidwa ndi kuyika mapepala achitsulo a silicon otsekedwa kuchokera kwa wina ndi mzake, ma coil oyambirira ndi apamwamba amavulazidwa ndi waya wa enamelled ndipo voteji yoyambira imayenderana ndi chiwerengero chawo chotembenukira.

Kuphatikiza pa izi, ma thiransifoma ena amagwira ntchito pazikhazikiko makumi angapo a kilohertz mazana angapo, ndipo ma transfoma awa amakhala osintha pafupipafupi.Ma transformer apamwamba nthawi zambiri sagwiritsa ntchito chitsulo, koma maginito pachimake.Ma transfrequency transformer ndi ophatikizika, okhala ndi ma coil ochepa oyambira ndi apachiwiri komanso kuchita bwino kwambiri.

3, High ndi otsika pafupipafupi thiransifoma kusiyana ndi kukhudzana.

Mafupipafupi osinthira thiransifoma pafupipafupi amakhala makumi a kilohertz mpaka mazana a kilohertz, thiransifoma imagwiritsa ntchito maginito pachimake, chigawo chachikulu chapakati ndi manganese zinc ferrite, izi zomwe zili mumtundu wapamwamba wa eddy pano ndizochepa, kutayika kotsika, kuchita bwino kwambiri. .Otsika mafupipafupi thiransifoma ntchito pafupipafupi kunyumba kwa 50 Hz, thiransifoma pachimake ndi zitsulo zofewa maginito zakuthupi, woonda pepala pakachitsulo zitsulo akhoza kwambiri kuchepetsa Eddy panopa imfa, koma kuposa mkulu pafupipafupi thiransifoma pachimake imfa akadali yaikulu.

Zomwezo linanena bungwe mphamvu thiransifoma, mkulu-pafupipafupi thiransifoma voliyumu otsika pafupipafupi thiransifoma ndi ang'onoang'ono, otsika kutentha m'badwo.Choncho, ambiri panopa ogula zamagetsi ndi maukonde mankhwala adaputala mphamvu, ndi kusintha kotunga magetsi, mkati mkulu-pafupipafupi thiransifoma ndi chigawo chofunika kwambiri cha kotunga magetsi kusintha.Mfundo yofunikira ndikutembenuza zolowetsa za AC kukhala DC kenako kudzera pa transistor kapena chubu chothandizira kumunda kukhala ma frequency apamwamba kudzera pamagetsi osinthira pafupipafupi, mukakonzanso zotulutsa, kuphatikiza magawo ena owongolera, voteji ya DC yokhazikika.

Mwachidule, otsika ndi otsika mafupipafupi thiransifoma ndi ofanana mu ntchito electromagnetic kupatsidwa ulemu mfundo, kusiyana otsika pafupipafupi thiransifoma ndi silikoni zitsulo pepala zakhala zikuzunza m'miyoyo pakati zitsulo, mkulu pafupipafupi thiransifoma ndi manganese nthaka ferrite ndi zinthu zina butt mu chipika chonse.
