Yintoni na inductance efanayo?

Mutual yoqheliso simo oxhasa ezininzi kuThixo izixhobo zombane. Amaninzi imeko, xa umntu ehlaselwa ngqo obubonakala kubomi bemihla ngemihla, kodwa musa nokuba ungazi nto ngaloo nto. Masikhumbule elidlulileyo kutshanje, apho engundoqo ulwazi zothumelo kuthetha ukuba Imiqondiso analog. Kwaye ngoku phantse zonke izixhobo ze-elektroniki ziye zidluliselwe iintlobo kwezwi yedijithali. Isibakala sokuba 'nani "yaziwa engcono bonke. Kodwa uyazibuza, yintoni kanye? Ngokuqinisekileyo, ezinye izindlu nakuba sele ifowuni igxunyekwe iinkonzo i PBX analog. Ukuba uthelekisa i "iiselula 'mihla yaye" nezakudala ", okukuthelekisa ngokucacileyo kwicala le yokugqibela. Yiva kwi imvelaphi incoko kuphazamiseka losasazo okanye igama elithi "best" isekhona unxibelelwano othile - oku akumangalisi. Oku kwenzeka ngenxa yokuba yocingo, iingcingo basondele omnye komnye, ngoko kukho yoqheliso mutual kwi imigca emibini. Omnye umzekelo ezo unqakrazo eliguquguqukayo ukubonakala izithethi le TV okanye izithethi computer yakho, xa kukho mobilka kwaye umnxeba. Ekugqibeleni, endala IDE-neengcingo kunye ababhexeshi-80 kusetyenziswa isiqingatha kuphela kubo, lo gama ezinye 40 kuthintela ineziphumo ezisa induction efanayo. Kukho imizekelo emininzi, yonke isiphumo akwenzi ngqiqo. Kubalulekile nje ukukhumbula ukuba kulo mzekelo, naziphi "crosstalk" - oku ke inductance efanayo.

Ngokuqhelekileyo, eli gama libhekisela inkqubo isenzeko kumandla electromotive (EMF) kwenye izinikezeli ezikufutshane ngexesha xa utshintsho kwezinye ixabiso ezikhoyo ngoku. Kakhulu sachaza nje induction mutual nge sombane. Xa uhlobo yayo elula (a kwimeko ezizodwa), nesiguquli liquka imibhijelo ezimbini isilonda kundoqo efanayo ngemagnethi. Xa ngoku aqukuqela wire elinye kubo, kukho ngeenxa yintsimi ngemagnethi. Ngenxa yoko wabonakala ekubhobhozeni magnetic ingena umqhubi coil yesibini, ukudala EMF kuyo. Wabonakala current eyabangelwa, ngokwaneleyo ukuba sivale ngeziphumo Ikhoyili, ukudala nomxokelelwane. Ngenxa yokwanda ngobunzulu wobhobhozayo Imagnethi kuyenyuka kunye inductance efanayo. Ukuze kufikelelwe iimpawu ezinqwenelekayo (umz, efficiency) usebenzisa izisombululo ezahlukeneyo: ukutshintsha uqwalaselo yesekethe magnetic; indlela ekhethekileyo lwenziwa jiko ngokubhijela kunye Ave inductance nokuhloniphana ilinganiswa variometer.

Njani na kuyo yonke imizekelo echazwe ekuqaleni kweli nqaku? elula kakhulu: phantse kuzo zonke iimeko (ngaphandle iifoni mobile) ibekwe kufuphi ababhexeshi eziliqela, ubuncinane enye bekuza umsinga wombane. Ngenxa yoko, kukho mhlaba otsalayo ovelisa ukubhobhoza ngemagnethi. Le yokugqibela, angena abaqhubi kufutshane ukhuthaza EMF kuzo, kwakunye kwitsheyini na, ke ngoko, ngokungqinelana nomthetho yoqheliso magnetic, uhamba yangoku. ulwalathiso bakhe kumiselwa ngokusebenzisa kolawulo Lenz.

Mutual zazisetyenziswa Electrical Engineering mihla. Ekubeni ezinye iziphumo zalo ezibuhlungu akade ekuqaleni kweli nqaku, iyavakala ukunika imizekelo luncedo. Enye yamacebo ezininzi ezaziwayo-kakuhle - somfanekiso mbane ikhaya. Ngaphakathi kukho sombane (idla uhlobo toroid) kunye nobuninzi ezinjengeetheminali, nganye kufanekisela ixabiso ethile ombane. Kwakhona, kwezinye izixhobo uyakwazi ukufumana isisombululo umdla - bodwa galvanic. Enyanisweni, oku nesiguquli efanayo (ngamanye amaxesha isibini photocoupler), kodwa hayi ukusebenzisa inani elikhoyo iinguqu. Ngenxa yoko, kunokwenzeka ukuba enze ekubhobhozeni magnetic ngokusebenzisa iindlela zonxibelelwano ezininzi, ukubonelela umgangatho ofanelekileyo wokhuseleko zombane. Production umzekelo, oko davit.
