Kungani engakunaki nokubhuza transformer: izimbangela futhi kungenzeka nokuqedwa umsindo

Uma e-United States ekuqaleni kwekhulu lamashumi amabili kwaba ukukhangisa ethandwa ku "Izinceku buthule". Umbuzo ukhathazekile amandla, noma kunalokho, ikhono layo buthule enze imisebenzi ehlukahlukene. General Electric Inkampani uye wafuna zidonse ukunaka kwanoma abathengi ukuba zasendlini. Kodwa uma touch a kungokomzimba wo inqubo, ugesi imisebenzi, ke ematfuba ukuphuma, okungukuthi enjalo 'ithule. " Isibonelo transformer owaziwa umshini uyakwazi ukukhiqiza impela Ukuduma komsindo omkhulu. Ngakho kungani kuyachwaza transformer?

Kanjani a transformer

Ukuze uqonde lokhu, kungaphazamisi khumbula esikoleni sifundo physics, echaza isimiso yokusebenza transformer. Transformer siphela ngesisekelo umthetho lokungeniswa kagesi. Kuhlanganisa wire ikhoyili isilonda ka diameters ezahlukene kanye nezinombolo ezahlukene ematfuba. Lezi ohlobo kukhona Windings aphansi nezamabanga aphakeme we transformer. Phakathi Windings sekunokuxhumana. It is zilandelwa ngu uhlobo izindandatho olukhethekile steel ferromagnetic. Ring wabizwa ngokuthi core futhi itholakala ngaphakathi Windings. kakhulu Umklamo core libuthene amapuleti mncane.

Lapho eyinhloko izinkampani ihlinzekwa kushintshana zamanje, uveza kazibuthe e ekujuleni kwenhliziyo. Le nkambu iyahlukahluka ngokuhambisana nezinguquko eyaqanjwa wamanje yayo. Futhi, lokungeniswa ensimini eheha electromotive sisebenza kuleli yesibili ikhoyili - aguqukile kagesi lamanje.

okokusebenza core sehlukaniswe sebuningini microregions. ingxenye ngayinye enjalo ngaphandle kobukhona i voltage okokufaka samanje nozibuthe iqondiswe okuphambene ngokuvamile komunye nomunye. Nokho, ngaphansi kokucindezeleka zonke izindikimba uqale ukuba aphuthume kwelinye direction, udala uzibuthe onamandla. Konke lokhu kuhambisana ushintsho izilinganiso ngokomzimba core. Manje ungabona ukuthi kungani kuyachwaza transformer.

magnetostriction

Njengoba insimu kushintshana, plate core bese uqalisa ekuhlehleni welulele ngesikhathi nabo. Le nqubo ibizwa ngokuthi magnetostriction. Ikhishwa ukunyakaza okunjalo kwenza nge imvamisa eliphezulu 100 Hz at a imvamisa samanje 50 Hz, isikhala iza vibration elinendawo band izwi futhi akachazeki by endlebeni yomuntu. Ngaphezu izinga ejwayelekile, lichaza ekwakheni AC has ngaphezulu imvamisa high Harmonics. Babengaphezu, transformer ngaphezulu ukulayishwa, okuyinto yena, kunyakaza obuhlabayo futhi ezwakalayo. Yingakho kuyachwaza transformer.

Okunye izimbangela kunomsindo transformer

Kodwa akuzona zonke izizathu ngenxa "talkativeness" transformer kufihlwe magnetostriction. Kungani laden transformer engakunaki nokubhuza? Emit umsindo:

• Transformer Windings. Lokhu kungenxa yokuthi i-magnetic ecucuza ezivivinya ukuba azixoshe ngokuhlobene emazombezombe core. Umsindo iyakhula esimweni kabi isilonda ikhoyili, uma iphendula ezimbi eduze komunye nomunye.
• amapuleti Core. Kungani? Transformer ngokuvamile babesha amashushu lapho bengakwamukeli futhi babe izikhala phakathi esipara. Khona-ke, ngaphezu kokucindezelwa, umsindo is wezwa ensimbini ikhala.

• Enesici, noma ukulimala ukwahlukanisa izintambo zethusi. Lokhu kungenzeka ukushuba emazombezombe, lapho kukhona izindawo ezinezinga lokushisa eliphakeme. Kulokhu, phakathi Windings kungaba lushelele inhlansi, kulandele ngokuchofoza. Ukudedelwa unamandla kakhulu, isici umsindo uzwakala ukuthi unejubane.
• Zonke Looseness e transformer kungani? Transformer ukudlidliza ngesikhatsi kokuhlinzwa, njengoba khenqeza.

Ukuze ugweme lokhu ethile, Transformers, izinhlobo buthule zenzelwe. icebo labo wakhiwa ngendlela yokuthi a wamanje imvamisa ukuguqulwa (ukwanda) ezingeni lapho vibration akuyona waqonda ku uhla audio. Lokhu 10 kHz nangaphezulu. Transformers ezithule lingakanani kanye nesisindo kuvamile kakhulu.

isiphetho

Hhayi ukuze zibuze umbuzo wokuthi kungani kuyachwaza transformer, wonke amamodeli enamandla udinga ukuthatha eliphezulu, abakhiqizi elihle. amandla okuphansi akunjalo afune izinto ngenkani kwabanye ekusebenzeni ukunemba. Kodwa uma isatholakala lapho transformer kwenza umsindo, ungazama ukuyisusa ngu igciwane amapuleti nge ngezikulufo. Kuphela uzame hhayi overzealous hhayi delaminate core sensimbi. Uma amabhawudo azitholakali, ukusetshenziswa nail noma i-glue, okuyinto ugcwele core. Ukuphungula ngisisho ngekhanda Windings kungenzeka kuphela ngosizo rewinding yabo.
