Chidziwitso cha Transformer

Transformer ndi chipangizo chomwe chimagwiritsa ntchito mfundo ya electromagnetic induction kuti isinthe magetsi a AC.Zigawo zake zazikulu zimaphatikizapo koyilo yoyamba, koyilo yachiwiri ndi chitsulo chachitsulo.

Mu ntchito yamagetsi, nthawi zambiri mumatha kuona mthunzi wa thiransifoma, zomwe zimagwiritsidwa ntchito kwambiri pamagetsi monga kutembenuka kwamagetsi, kudzipatula.

Mwachidule, chiŵerengero cha voteji cha ma coils oyambirira ndi apamwamba ndi ofanana ndi chiŵerengero cha kutembenuka kwa ma coils oyambirira ndi apamwamba.Chifukwa chake, ngati mukufuna kutulutsa ma voltages osiyanasiyana, mutha kusintha kuchuluka kwa ma coils.

Malinga ndi ma frequency osiyanasiyana ogwiritsira ntchito ma transfoma, amatha kugawidwa m'magawo otsika kwambiri komanso ma transfrequency transfoma.Mwachitsanzo, m'moyo watsiku ndi tsiku, ma frequency amagetsi osinthira mphamvu ndi 50Hz.Timatcha thiransifoma ntchito pafupipafupi otsika pafupipafupi thiransifoma;Ma frequency ogwiritsira ntchito osinthira ma frequency apamwamba amatha kufika makumi a kHz mpaka mazana a kHz.

Voliyumu ya transformer yothamanga kwambiri ndi yaying'ono kwambiri kuposa ya otsika-frequency transformer yokhala ndi mphamvu yotulutsa yomweyi.

Transformer ndi gawo lalikulu kwambiri pamagawo amagetsi.Ngati mukufuna kuti voliyumu ikhale yaying'ono ndikuwonetsetsa mphamvu yotulutsa, muyenera kugwiritsa ntchito chosinthira chapamwamba kwambiri.Chifukwa chake, ma transfoma apamwamba kwambiri amagwiritsidwa ntchito posinthira magetsi.

Mfundo yogwira ntchito ya high frequency transformer ndi low frequency transformer ndi yofanana, zonsezi zimatengera mfundo ya electromagnetic induction.Komabe, ponena za zipangizo, "cores" awo amagwiritsa ntchito zipangizo zosiyanasiyana.

Pakatikati pachitsulo cha transformer yotsika kwambiri nthawi zambiri imakhala ndi mapepala ambiri azitsulo za silicon, pomwe chitsulo chachitsulo chosinthira ma frequency apamwamba chimapangidwa ndi maginito apamwamba kwambiri (monga ferrite).(Choncho, chitsulo chachitsulo cha high-frequency transformer nthawi zambiri chimatchedwa magnetic core)

Mu DC yokhazikika yamagetsi yamagetsi, chosinthira chotsika pafupipafupi chimatumiza siginecha ya sine wave.

Posinthira magetsi, thiransifoma yothamanga kwambiri imatumiza siginecha yothamanga kwambiri.

Pa mphamvu yovotera, chiŵerengero chapakati pa mphamvu yotulutsa ndi mphamvu yowonjezera ya transformer imatchedwa mphamvu ya transformer.Pamene mphamvu yotulutsa thiransifoma ikufanana ndi mphamvu yowonjezera, mphamvuyo ndi 100%.Ndipotu, transformer yotereyi kulibe, chifukwa kutaya kwa mkuwa ndi kutayika kwachitsulo kulipo, transformer idzakhala ndi zotayika zina.

Kodi kutaya mkuwa ndi chiyani?

Chifukwa koyilo ya thiransifoma imakhala ndi kukana kwina, pomwe pano ikudutsa mu coil, gawo la mphamvuyo lidzakhala kutentha.Chifukwa koyilo ya thiransifoma imavulazidwa ndi waya wamkuwa, kutayika kumeneku kumatchedwanso kutaya kwa mkuwa.

Kodi kutayika kwachitsulo ndi chiyani?

Kutayika kwachitsulo kwa thiransifoma kumaphatikizapo mbali ziwiri: kutaya kwa hysteresis ndi kutayika kwa eddy;Hysteresis imfa imatanthawuza kuti pamene kusinthasintha kwamakono kumadutsa mu koyilo, mizere ya maginito ya mphamvu idzapangidwa kuti idutse pakati pa chitsulo, ndipo mamolekyu omwe ali mkati mwachitsulo amatsitsirana wina ndi mzake kuti apange kutentha, motero amawononga mbali ya mphamvu yamagetsi;Chifukwa mphamvu ya maginito imadutsa pakati pa chitsulo, chitsulo chachitsulo chidzapanganso mphamvu yamagetsi.Chifukwa chapano chikuzungulira, chimatchedwanso eddy current, ndipo kutayika kwapano kwa eddy kudzadyanso mphamvu yamagetsi.
