ng'anjo yapakatikati yapakatikati

Ng'anjo yapakatikati AMAGWIRITSA NTCHITO magetsi apakati pakuwotcha, kusungunula ndi kuteteza kutentha.Sing'anga pafupipafupi ng'anjo makamaka ntchito smelting mpweya zitsulo, aloyi zitsulo, mtundu wa zitsulo, komanso angagwiritsidwe ntchito mkuwa, zotayidwa ndi zina sanali achitsulo kusungunula zitsulo ndi kutentha raising.Small kukula, kulemera kuwala, mkulu mlingo, otsika mphamvu mowa. , kusungunuka kwachangu, kosavuta kulamulira kutentha kwa ng'anjo, ng'anjo yapamwamba yopangidwa ndi ng'anjo yapakati nthawi zambiri imagwiritsidwa ntchito popanga fakitale ndi chithandizo cha kutentha.Wapakati pafupipafupi ng'anjo pang'onopang'ono m'malo malasha ng'anjo, gasi ng'anjo, mafuta ng'anjo ndi wamba kukana ng'anjo, ndipo wakhala ankakonda watsopano mu fakitale kuponyera ndi kutentha mankhwala.One, sing'anga pafupipafupi ng'anjo ntchito mfundoWapakatikati pafupipafupi ng'anjo kudzera pakachitsulo ankalamulira rectifier inverter kupanga wapakatikati. mphamvu pafupipafupi, anatumiza kwa ng'anjo thupi koyilo, ng'anjo (koyilo) pakati pa sing'anga pafupipafupi electromagnetic munda, kuti zitsulo mu ng'anjo thupi kutulutsa Eddy panopa, Eddy panopa ndiyeno kupanga zitsulo kutulutsa kuchuluka kwa kutentha kotero. ng'anjo yapakatikati ya ng'anjo yapakatikati imapangidwa ndi magetsi, mphete yolumikizira ndi crucible yopangidwa ndi zinthu zokanira mu mphete yolowera. kutulutsa maginito osinthira maginito mu koyilo yolowera, chingwe champhamvu chamagetsi mu ng'anjo yowotchera moto, chitsulo chimapangidwa mu ng'anjo yopangira ma electromotive mphamvu, chifukwa cholemetsa chokha chimapanga chipika chotsekeka, mfundo yokhotakhota iyi imangotembenuka ndipo Chotsekedwa.Choncho, inductive current imapangidwa nthawi imodzi mumalipiro.Pamene mpweya wonyengedwa umadutsa pamtengowo, ndalamazo zimatenthedwa kuti zisungunuke.Njira yogwira ntchito ya ng'anjo yapakatikati ya ng'anjo imakhalanso ngati chophika chophika, motere: choyamba, kupyolera mu inverter magetsi, kusinthasintha kwa magawo atatu. rectifier panopa (SCR) mu gawo limodzi dc, ndiye ndi inverter mlatho inverter mu mtundu wa alternating panopa (ac), 500-1000 Hz pafupipafupi kugunda kudzera mkuwa mapangidwe mphete mu ng'anjo maginito, kupanga bwalo zitsulo zimapanga eddy panopa. magnetic field, eddy current imayenda muzitsulo zotentha, imapanga kutentha, kuti ikwaniritse cholinga chosungunula zitsulo. Mafupipafupi a ng'anjo yamagetsi yamagetsi ndi 800-20000Hz. makinawo amatengera gawo la magawo atatu a mlatho wowongolera, inverter imatenga gawo limodzi la gawo limodzi la mlatho wozungulira, katunduyo ndi mawonekedwe ofanana, ulalo wosefera wa DC ndi kusefa kwakukulu kwa inductance, kuti akwaniritse zofunikira zolowetsa za ma inverters ofanana.
