Ndeipi migumisiro yekudonha kwepakati petransformer?

Musiki wekutanga: Chiedza cheMidziyo

Mukuongorora matransformer mufekitori, ma magnetic cores mazhinji etransformer haana mablocks nekuda kwekukanganiswa kwema bumps kana fixture pressure. Ndeipi mhedzisiro yekudonha kwe transformer core? Chinyorwa chino chichakurukura zviri mukati mayo.
Tinoziva kuti mumatransformer, basa guru re magnetic core nderekupa magnetic circuit, zvichibvumira transformer kutakura simba zvinobudirira. Izvi zvinogonawo kuratidzwa zvakanaka mu formula yekuverenga ye inductance:

Kazhinji, tinoona kubvumidzwa kwemhepo se1, nepo kubvumidzwa kwemagineti kunogona kusvika pamakumi, uye akawanda anogona kusvika zviuru kana kunyange makumi ezviuru.
Kubva pamaonero aya, ma transformer ane ma magnetic cores anowedzera zvakanyanya inductance yawo, uye simba rinochengetwa uye rinotumirwa rinogonawo kuwedzerwa zvinoenderana. Kushanda zvakanaka kwe transmission yavo kuchavandudzwawo kusvika pamwero wakati.
Pamusoro pezvo, musimboti wetransformer une rutsigiro rwakati rwechimiro pane chigadzirwa chose chetransformer, izvo zvinobatsira kuchengetedza kugadzikana kwetransformer uye kuderedza ruzha nekudedera.

Kana paine bhuroko risipo mu core ye transformer, zvinokanganisa kufambiswa kwe magnetic circuit yakajairika. Kana magnetic core isipo, chikamu chekutanga che magnetic core chinova mhepo, zvichikonzera kuwedzera kwe magnetic resistance, kudzikira kwekushanda, uye muzviitiko zvakakomba, kudzikira kwe inductance, zvichiisa panjodzi kushanda kwakajairika kwemuchina wese.
Mamwe matransformer anewo macore emagineti asipo. Munguva yekushanda kwenguva refu kwemuchina wese, macracks ari mukati mecore yemagineti (chikamu chisina kudonha kubva pablock) anokurumidza uye anokura, zvichikonzera kurasikirwa kwakanyanya uye kukwira kwetembiricha yetransformer yese, izvo zvinozoita kuti muchina ushaye simba.

Kubva pamaonero aya, kushaikwa kwema "magnetic core blocks" muma "transformers" hakungokanganisi mashandiro chete, asiwo kune simba pakushanda uye kuvimbika kwema "transformers". Parizvino, zviyero zvekuonekwa kwe "magnetic core chipping" yevagadziri vazhinji ndeizvi: nzvimbo ye "chipping" imwe chete haifanirwe kudarika 3% yenzvimbo yese ye "magnetic core", uye nzvimbo ye "chipping" mbiri kana kupfuura haifanirwe kudarika 5%.
Vamwe vagadziri vanewo misiyano, iyo isingazotsanangurwi pano. Chinhu chikuru musiyano uripo pakati pemagadzirirwo pakati pevagadziri, izvo zvinoita kuti pave nematanho akasiyana ekudzora.

Zvichienzaniswa nezvinodiwa, tinotenda kuti chikonzero chekudonha kwepakati petransformer chinonyanya kukosha. Kunyanya kana tichitungamirirwa nemasimba ekunze, pamusoro pepakati petransformer hapagoni kudonha chete, asi zvinogonawo kukonzera mitswe mukati mepakati petransformer, uye njodzi haigone kungoongororwa chete.
Muchiitiko ichi, kuitika kwekuputsika kwemagnetic core mu transformer kunonyanya kukosha kuti titarisire uye tifunge nezvako.
