Incazelo eningiliziwe yeshidi lensimbi ye-silicon ye-transformer!

Siyazi ukuthi i-transformer yangempela isebenza njalo esimweni se-AC, futhi ukulahleka kwamandla akukhona nje kuphela ekumelaneni kwekhoyili, kodwa futhi nasenhlokweni yensimbi ngaphansi kwe-magnetization yamandla ashintshanayo. Ukulahleka kwamandla enhlokweni yensimbi kuvame ukubizwa ngokuthi "ukulahlekelwa yinsimbi". Ukulahleka kwensimbi kubangelwa izizathu ezimbili, esinye "ukulahlekelwa yi-hysteresis" kanti esinye "ukulahlekelwa yi-eddy current".

Ukulahleka kwe-hysteresis ukulahlekelwa yinsimbi okubangelwa yi-hysteresis ngesikhathi senqubo yokuzibutha kwe-iron core. Ubukhulu balokhu kulahlekelwa buhambisana nobukhulu bendawo evalwe yi-hysteresis loop yezinto. I-hysteresis loop yensimbi ye-silicon incane, kanti ukulahleka kwe-hysteresis kwe-iron core ye-transformer kuncane, okunganciphisa kakhulu izinga lokukhiqizwa kokushisa.

Njengoba insimbi ye-silicon inezinzuzo ezingenhla, kungani ungasebenzisi ucezu lonke lwensimbi ye-silicon njenge-core yensimbi, kodwa futhi uyicubungule ibe ama-flakes? Lokhu kungenxa yokuthi i-chip core inganciphisa olunye uhlobo lokulahlekelwa yinsimbi - "ukulahlekelwa kwamanje kwe-eddy".

Uma i-transformer isebenza, kukhona ugesi oshintshashintshayo kukhoyili, futhi ugesi ophumayo ophumayo uyashintshashintsha. Lokhu kushintsha kogesi ophumayo kubangela ugesi ophumayo enkabeni yensimbi. Ugesi ophumayo ophumayo enkabeni yensimbi ujikeleza endizeni uqonde ngqo ohlangothini logesi ophumayo, ngakho-ke ubizwa ngokuthi ugesi ophumayo.

Ukulahleka kwamanje we-Eddy nakho kuyashisa ingaphakathi. Ukuze kuncishiswe ukulahleka kwamanje we-eddy, ingaphakathi lensimbi le-transformer lenziwe ngamashidi ensimbi ye-silicon ahlanganiswe ngokushisa komunye nomunye, ukuze i-eddy current idlule engxenyeni encane enqamulayo ku-loop encane nende ukuze kwandiswe ukumelana endleleni yamanje we-eddy; ngesikhathi esifanayo, i-silicon ensimbini ye-silicon yenza ukumelana kwezinto kukhule, okusebenza futhi ekunciphiseni i-eddy currents.

Engxenyeni yensimbi ye-transformer, ishidi lensimbi ye-silicon eligoqwe ngokubandayo elinobukhulu obungu-0.35mm livame ukusetshenziswa. Ngokusho kobukhulu bengxenye yensimbi edingekayo, lisikwa libe yingcezu ende, bese lihlanganiswa libe yisimo "sosuku" noma isimo "somlomo". Ngokwemfundiso, ukuze kuncishiswe ugesi we-eddy, lapho ugesi weshidi lensimbi ye-silicon uba mncane futhi uma ishidi elihlanganisiwe lincipha, umphumela uba ngcono. Lokhu akugcini nje ngokunciphisa ukulahleka kogesi we-eddy kanye nokwenyuka kwezinga lokushisa, kodwa futhi kusindisa izinto ezisetshenziselwa amashidi ensimbi ye-silicon.

Kodwa empeleni uma kwenziwa insimbi yensimbi ye-silicon steel sheet. Akuveli nje kuphela ezintweni ezinhle ezishiwo ngenhla, ngoba ukukhiqizwa kwensimbi kuzokwandisa kakhulu amahora okusebenza komuntu futhi kunciphise ukusebenza kahle kwensimbi yensimbi. Ngakho-ke, lapho sisebenzisa amashidi ensimbi ye-silicon ukwenza ama-transformer core, kumelwe siqhubeke nesimo esithile, silinganise izinzuzo nezingozi, bese sikhetha usayizi ongcono kakhulu.

Ama-transformer enziwa ngokwesimiso sokungeniswa kwe-electromagnetic. Kunezimbobo ezimbili, i-primary winding, kanye ne-secondary winding, eziboshwe emlenzeni ovaliwe we-core. Uma i-primary winding iphambene ne-voltage yokunikezwa kwamandla kagesi e-AC. Kukhona i-alternating current eqenjini lokuqala le-Rao, bese kuba khona i-magnetic potential, bese kukhiqizwa i-alternating main magnetic flux e-iron core ngaphansi kwesenzo se-magnetic potential.

Ngokuqondene nokuthi kungani ingakhushulwa, futhi iboshwe? Khona-ke idinga ukuchazwa ngumthetho kaLenz. I-magnetic flux ekhiqizwa yi-induced current ihlala ivimbela ushintsho lwe-circular magnetic flux. Lapho i-magnetic flux yokuqala ikhula, i-magnetic flux ekhiqizwa yi-induced current iphambene ne-magnetic flux yokuqala, okungukuthi, eyesibili I-magnetic flux ekhiqizwa yi-winding iphambene ne-magnetic flux eyinhloko ekhiqizwa yi-primary winding, ngakho-ke kuvela i-voltage eshintshanayo ephansi ekujikeni kwesibili. Ngakho-ke, i-iron core iyingxenye yesekethe ye-magnetic ye-transformer.

Ishidi lensimbi le-silicon
