ICanwin iyiNkampani Yokuguqula Amandla Kagesi & Umkhiqizi Wesiguquli Kagesi
Ama-transformer cores asetshenziswa kakhulu ngokuvamile enziwa ngamashidi ensimbi ye-silicon. I-Silicon steel iwuhlobo lwensimbi eyenziwe nge-silicon (i-silicon ibizwa nangokuthi i-silicon), kanti okuqukethwe kwayo kwe-silicon kungu-0.8 kuya ku-4.8%. Umnyombo wensimbi we-transformer wenziwe ngensimbi ye-silicon ngoba insimbi ye-silicon ngokwayo iyinto yamagnetic enokungena okuqinile kazibuthe.
Siyazi ukuthi i-transformer yangempela isebenza ngaso sonke isikhathi esimweni se-AC, futhi ukulahlekelwa kwamandla akukhona nje ukumelana nekhoyili, kodwa futhi kumgogodla wensimbi ngaphansi kwe-magnetization yamanje eshintshanayo. Ukulahlekelwa kwamandla kumongo wensimbi ngokuvamile kubizwa ngokuthi "ukulahlekelwa kwensimbi". Ukulahleka kwe-iron kubangelwa izizathu ezimbili, esinye "ukulahlekelwa yi-hysteresis" kanti esinye "ukulahlekelwa kwe-eddy yamanje".
Ukulahlekelwa kwe-hysteresis ukulahlekelwa kwensimbi okubangelwa i-hysteresis phenomenon phakathi nenqubo ye-magnetization ye-iron core. Ubukhulu balokhu kulahlekelwa bulingana nobukhulu bendawo evalwe yi-hysteresis loop yezinto. I-hysteresis loop yensimbi ye-silicon incane, futhi ukulahlekelwa kwe-hysteresis yensimbi ye-transformer kuncane, okunganciphisa kakhulu izinga lokukhiqiza ukushisa.
Njengoba insimbi ye-silicon inalezi zinzuzo ezingenhla, kungani ungasebenzisi lonke ucezu lwensimbi ye-silicon njengomgogodla wensimbi, kodwa futhi uyicubungule ibe ama-flakes? Lokhu kungenxa yokuthi i-chip core inganciphisa olunye uhlobo lokulahlekelwa kwensimbi - "ukulahlekelwa kwamanje kwe-eddy".
Lapho i-transformer isebenza, kuba khona amandla ashintshayo kukhoyili, futhi i-flux kazibuthe eyikhiqizayo iyashintshana. Lokhu kushintsha kwe-magnetic flux kubangela i-current in the iron core. I-current induced ekhiqizwa kumongo wensimbi izungeza endizeni iqonde ngqo lapho kugeleza khona kazibuthe, ngakho ibizwa ngokuthi i-eddy current.
Ukulahlekelwa kwamanje kwe-Eddy nakho kushisa umnyombo. Ukuze kuncishiswe ukulahlekelwa kwamanje kwe-eddy, i-iron core ye-transformer yenziwe ngamashidi ensimbi e-silicon ahlanganiswe komunye nomunye, ukuze i-eddy current idlule engxenyeni encane yesiphambano ku-loop encane futhi ende ukwandisa ukumelana. endleleni yamanje ye-eddy; ngesikhathi esifanayo, i-silicon ensimbi ye-silicon yenza i-Resistivity yezinto ezibonakalayo ikhule, ephinde isebenze ekunciphiseni ama-eddy currents.
Ngomgogodla wensimbi we-transformer, kusetshenziswa ishidi lensimbi ye-silicon egoqwe ngokubanda enogqinsi oluyi-0.35mm. Ngokusho kobukhulu bensimbi edingekayo, inqunywa ibe yisiqephu eside, bese ihlanganiswa ibe yisimo "sosuku" noma umumo "womlomo". Uma sikhuluma ngokwethiyori, ukuze kwehliswe i-eddy current, ukuncipha kokuqina kweshidi lensimbi ye-silicon kanye nokuncipha kweshidi elihlukene, umphumela uba ngcono. Lokhu akugcini nje ukunciphisa ukulahleka kwamanje kwe-eddy kanye nokukhuphuka kwezinga lokushisa, kodwa futhi kusindisa izinto ezisetshenziselwa amashidi ensimbi ye-silicon.
Kodwa empeleni lapho wenza i-silicon steel sheet iron core. Akukona nje kuphela ezicini ezithandekayo ezibalwe ngenhla, ngoba ukukhiqizwa kwensimbi kuzokwandisa kakhulu amahora-amahora futhi kunciphise ukuphambana okuphumelelayo kwe-iron core. Ngakho-ke, lapho sisebenzisa amashidi ensimbi ye-silicon ukwenza ama-cores e-transformer, kufanele siqhubekele esimweni esithile, silinganise izinzuzo nezingozi, futhi sikhethe usayizi ongcono kakhulu.
Ama-transformer enziwa ngokulandela isimiso sokungeniswa kwe-electromagnetic. Kunama-windings amabili, ukujika okuyinhloko, kanye nokujika kwesibili, inxeba emlenzeni ophakathi ovaliwe. Uma ukujikajika okuyinhloko kungamanga ku-voltage kagesi we-AC. Kukhona umsinga oshintshanayo eqenjini langempela le-Rao, futhi amandla kazibuthe ayasungulwa, futhi ukushintshashintsha okuyinhloko kazibuthe kukhiqizwa engxenyeni yensimbi ngaphansi kwesenzo samandla kazibuthe.
Ngokuqondene nokuthi kungani ingakhuliswa, futhi ikhishwe? Bese idinga ukuchazwa ngumthetho kaLenz. I-flux kazibuthe ekhiqizwa i-current induced ihlale ivimbela ukuguqulwa kwe-circular magnetic flux. Lapho i-flux yasekuqaleni kazibuthe ikhula, ukugeleza kazibuthe okukhiqizwe amandla kazibuthe kuphambene ne-flux yasekuqaleni kazibuthe, okungukuthi, eyesibili I-flux yamagnetic eyenziwe yi-winding iphambene ne-magnetic flux eyinhloko ekhiqizwa ukuzungeza okuyinhloko, ngakho-ke. i-voltage eshintshashintshayo enezinga eliphansi ivela endaweni ephendukayo yesibili. Ngakho-ke, i-iron core iyingxenye yesifunda kazibuthe ye-transformer.
I-Silicon steel sheet
Ishidi lensimbi ye-silicon elisetshenziswa ugesi livame ukubizwa ngokuthi i-silicon steel sheet noma ishidi le-silicon steel. Njengoba igama lisho, iyinsimbi kagesi ye-silicon enokuqukethwe kwe-silicon efinyelela ku-0.8% -4.8%, eyenziwe ngokugoqeka okushisayo nokubanda. Ngokuvamile, ubukhulu bungaphansi kwe-1mm, ngakho-ke kubizwa ngokuthi ipuleti elincane.
