Ndeipi yakawiriranwa inductance?

Mutual induction Fani irimo munhu muzvizhinji kuti magetsi mano. Kazhinji mamiriro, kana munhu akasangana zvakananga kuonekwa muupenyu hwezuva nezuva, asi havazivi nezvazvo. Ngationei kuyeuka ichangobva kare, apo mukuru mashoko yedzimudzangara nzira dzakanga analoginen anonongedzera. Zvino zvinenge zvose yemagetsi midziyo vave kune digitaalinen vachisiyanisa inzwi mhando. Chokwadi chokuti "nhamba" iri nani kuzivikanwa vose. Asi iwe vanoshamisika, chii chaizvo? Chokwadi, dzimwe dzimba vachiri vane the wired dzorunhare Serviced nemunhu analoginen PBX. Kana iwe enzanisa mashoko ano "mobile nhare" uye "oldies", fananidzo zvakajeka kwete nyasha chechipiri. Inzwai pamusoro pakanyorwa kurukurirano ndatovhiringidza nhepfenyuro kana kunyange "zvakanakisisa" Shoko ichiri kukurukurirana munhu - ichi hazvishamisi. Izvi zvinoitika nokuti parunhare wire, tambo vari pedyo nepedyo, saka pane yakawiriranwa induction ari misara miviri. Mumwe muenzaniso avo pulsating the clicks iri TV kuti vakurukuri kana kombiyuta yako vakurukuri, kana paine mobilka uye kudanwa. Pakupedzisira, vatana Ide-netambo pamwe 80 conductors kushandiswa chete hafu yavo, nepo vamwe 40 kudzivisa migumisiro chinounza yakawiriranwa induction. Kune mienzaniso yakawanda, vose mugumisiro hazvina musoro. Zvakakosha chete kuyeuka kuti iyi nyaya, chero "crosstalk" - ichi ndicho yakawiriranwa inductance.

Kazhinji, izvi izwi rinoreva nedanho panowanikwa ane electromotive simba (EMF) muna rimwe pedyo conductors panguva apo kuchinja zvimwe huripo kukosha ano. Most nyore akatsanangura yakawiriranwa induction ane transformer. In yayo nyore chimiro (nyaya chaiyo), kuti transformer unotora Coils maviri vanga pamusoro chete rinobva core. Kana ano runoyerera napakati waya wavo, pane kumativi ari remagineti. Naizvozvo akazviratidza rinobva nekubudisa chinopinda wechipiri coils kondakita, nokusika emf mairi. Akazviratidza vakafurira ano, zvakakwana kuvhara zvakawanwa pakati coils, pakusika nengetani. With kuwedzera kukuru pamusoro rinobva nekubudisa ichiwedzerwa uye tose inductance. Kuti vabudirire unodikanwa unhu (semuenzaniso, kushanda zvakanaka) vari kushandisa zvinogadzirisa dzakasiyana: kusandura configuration ari rinobva redunhu; inokosha nzira zvaakafunga ichitenderera Coils uye Ave. dzekuno inductance kunoyerwa ane variometer.

Sei kunoratidzwa muna mienzaniso ambotaurwa munyaya ino? nyore kwazvo: kazhinji kacho (kunze Mobile nhare) dziri pedyo conductors akawanda, pane imwe iyo inopfuura magetsi. Somugumisiro, pane remagineti generating rinobva nekubudisa. Ekupedzisira, rakapinza conductors pedyo induces EMF mavari, uyewo nengetani Saka, maererano nemutemo wenyika remagetsi induction, munhu kuitika Rwako. nhungamiro yake vagara vafungirwa nokushandisa nokutonga Lenz.

Mutual zvinowanzoshandiswa ano magetsi mapurani. Sezvo zvimwe zvayo kunaka migumisiro vakaverengwa kwokutanga munyaya ino, zvine musoro kuti kupa mienzaniso anobatsira. Mumwe inozivikanwa zvikuru mano - mhuri stabilizer mains. Inside pane transformer (kazhinji toroid mhando) pamwe muzvizhinji pamusoro zviteshi, chimwe nechimwe unoenderana imwe voltage ukoshi. Uyewo, pane dzimwe namano unogona kuwana inonakidza mhinduro - galvanic zindoga. Kutaura zvazviri, izvi ndiwo transformer (dzimwe nguva photocoupler hangaiwa), asi kwete kushandisa kuchinja coefficient. Somugumisiro, zvinobvira kuita rinobva nekubudisa kuburikidza vakawanda kukurukura nzira, ichipa zvakakodzera pamwero magetsi kuchengeteka. Production Somuenzaniso, davit.
