Okokuqala, malunga nokuba amandla anokugcinwa na, makhe sijonge umahluko phakathi kweenguqu ezifanelekileyo kunye neziguquli ezisebenzayo:
1. Inkcazo kunye neempawu zee-transformers ezifanelekileyo
Iindlela zokudweba eziqhelekileyo zee-transformers ezifanelekileyo
I-transformer efanelekileyo yinto efanelekileyo yesekethe. Ithatha: akukho ukuvuza kwamagnetic, akukho ukulahleka kobhedu kunye nokulahlekelwa kwentsimbi, kunye ne-self-inductance engapheliyo kunye ne-coefficients ye-inductance efanayo kwaye ayitshintshi ngexesha. Ngaphantsi kwezi ngcinga, i-transformer efanelekileyo iqonda kuphela ukuguqulwa kwe-voltage kunye nangoku, ngaphandle kokubandakanya ukugcinwa kwamandla okanye ukusebenzisa amandla, kodwa idlulisela kuphela igalelo lamandla ombane ekupheleni kokuphuma.
Ngenxa yokuba akukho kuvuza kwamagnetic, intsimi yamagnetic ye-transformer efanelekileyo ivalelwe ngokupheleleyo kumbindi, kwaye akukho mandla ombane wemagnethi aveliswa kwindawo ejikelezileyo. Ngexesha elifanayo, ukungabikho kokulahleka kobhedu kunye nokulahlekelwa kwentsimbi kuthetha ukuba i-transformer ayiyi kuguqula amandla ombane ekushiseni okanye ezinye iindlela zokulahlekelwa kwamandla ngexesha lokusebenza, kwaye ayiyi kugcina amandla.
Ngokomxholo we "Imigaqo yeSekethe": Xa i-transformer enentsimbi yentsimbi isebenza kwi-unsaturated core, i-magnetic permeability inkulu, ngoko i-inductance inkulu, kwaye ilahleko engundoqo ayinanto, inokuthi ithathwe njengento efanelekileyo. isitshintshi.
Masiphinde sijonge kwisigqibo sakhe. “Kwisiguquli esifanelekileyo, amandla afunxwa kukujija okuphambili yi-u1i1, kwaye amandla afunxwa kukujija okwesibini ngu-u2i2=-u1i1, oko kukuthi, igalelo lamandla kwicala eliphambili le-transformer liphuma kumthwalo ngokusebenzisa icala lesibini. Amandla apheleleyo athathwe yi-transformer yi-zero, ngoko ke i-transformer efanelekileyo iyingxenye engagcini amandla okanye isebenzise amandla.
” Ngokuqinisekileyo, abanye abahlobo nabo bathi kwisiphaluka se-flyback, i-transformer inokugcina amandla. Enyanisweni, ndihlolisise ulwazi kwaye ndafumanisa ukuba i-transformer yayo yokuphuma inomsebenzi wokugcina amandla ngaphezu kokufezekisa ukuhlukaniswa kombane kunye nokuhambelana nombane.Owokuqala yipropati ye-transformer, kwaye le yokugqibela yipropati ye-inductor.Ngoko ke, abanye abantu bayibiza ngokuba yi-inductor transformer, oku kuthetha ukuba ukugcinwa kwamandla ngokwenene kuyipropati ye-inductor.
2. Iimpawu ze-transformer ekusebenzeni kwangempela
Kukho umlinganiselo othile wokugcinwa kwamandla ekusebenzeni kwangempela. Kwiinguqu zangempela, ngenxa yezinto ezifana nokuvuza kwamagnetic, ukulahleka kobhedu kunye nokulahlekelwa kwentsimbi, i-transformer iya kuba nenani elithile lokugcinwa kwamandla.
Ingundoqo yentsimbi ye-transformer iya kuvelisa ilahleko ye-hysteresis kunye nelahleko yangoku ye-eddy phantsi kwesenzo se-alternating field magnetic. Ezi lahleko ziya kudla inxalenye yamandla ngokohlobo lwamandla obushushu, kodwa ziya kubangela ukuba umlinganiselo othile wamandla emagnethi ugcinwe kumbindi wentsimbi. Ngoko ke, xa i-transformer ifakwe ekusebenzeni okanye inqunyulwe, ngenxa yokukhululwa okanye ukugcinwa kwamandla amagnetic kwi-core iron, i-overvoltage yexesha elifutshane okanye i-surge phenomenon ingenzeka, ibangele impembelelo kwezinye izixhobo kwinkqubo.
3. Iimpawu zokugcina amandla e-inductor
Xa i-current in the circuit iqala ukwanda, iinductoriyakuthintela utshintsho lwangoku. Ngokomthetho we-electromagnetic induction, i-self-induced force electromotive iveliswa kuzo zombini iziphelo ze-inductor, kwaye isalathiso saso sichasene nolwalathiso lwenguqu yangoku. Ngeli xesha, unikezelo lwamandla lufuna ukoyisa i-self-induced electromotive force ukwenza umsebenzi kunye nokuguqula amandla ombane abe yimagnethi yamandla kwi-inductor yokugcina.
Xa ikhoyo ngoku ifikelela kwisimo esizinzile, intsimi yamagnetic kwi-inductor ayisayi kutshintsha, kwaye i-self-induced force electromotive i-zero. Ngeli xesha, nangona i-inductor ingasawathathi amandla kunikezelo lwamandla, isawagcina amandla emagnethi agcinwe ngaphambili.
Xa i-current in circuit iqala ukunciphisa, i-magnetic field kwi-inductor iya kuba buthathaka. Ngokomthetho we-electromagnetic induction, i-inductor iya kuvelisa i-self-induced force electromotive kwicala elifanayo nokuncipha kwangoku, ukuzama ukugcina ubukhulu bangoku. Kule nkqubo, amandla ombane agcinwe kwi-inductor aqala ukukhululwa kwaye aguqulelwe kumandla ombane ukuze abuyele kwisekethe.
Ngenkqubo yayo yokugcina amandla, sinokuqonda ngokulula ukuba xa kuthelekiswa ne-transformer, igalelo lamandla kuphela kwaye akukho mveliso yamandla, ngoko ke amandla agcinwa.
Oku kungasentla luluvo lwam lobuqu. Ndiyathemba ukuba iya kunceda bonke abaqulunqi beebhokisi ezipheleleyo ze-transformers ukuqonda abaguquli kunye nee-inductors! Ndingathanda ukwabelana nawe ngolwazi lwezenzululwazi:ii-transformers ezincinci, i-inductors, kunye ne-capacitors ezidityanisiweyo kwizinto zombane zendlu kufuneka zikhutshwe ngaphambi kokuba zichukumise okanye zilungiswe ngabaqeqeshi emva kokuphela kombane!
