Okokuqala, mayelana nokuthi amandla angagcinwa yini, ake sibheke umehluko phakathi kwama-transformer afanelekile kanye nama-transformer asebenzayo:
1. Incazelo kanye nezici zama-transformer afanelekile
Izindlela zokudweba ezivamile zama-transformers afanelekile
I-transformer efanelekile iyisici sesekethe esifanelekile. Ithatha ngokuthi: akukho ukuvuza kazibuthe, akukho ukulahlekelwa kwethusi nokulahlekelwa kwensimbi, kanye ne-self-inductance engapheli kanye ne-mutual inductance coefficients futhi ayishintshi ngokuhamba kwesikhathi. Ngaphansi kwalokhu kucatshangelwa, i-transformer ekahle ibona kuphela ukuguqulwa kwe-voltage kanye neyamanje, ngaphandle kokufaka isitoreji samandla noma amandla adlayo, kodwa idlulisela kuphela amandla kagesi okufakwayo ekupheleni kokukhipha.
Ngenxa yokuthi akukho ukuvuza kazibuthe, inkambu kazibuthe ye-transformer ekahle ivalelwe ngokuphelele enkabeni, futhi awekho amandla kazibuthe akhiqizwa endaweni ezungezile. Ngesikhathi esifanayo, ukungabikho kokulahlekelwa kwethusi nokulahlekelwa kwensimbi kusho ukuthi i-transformer ngeke iguqule amandla kagesi ekushiseni noma ezinye izinhlobo zokulahlekelwa kwamandla ngesikhathi sokusebenza, futhi ngeke igcine amandla.
Ngokusho kokuqukethwe "Kwizimiso Zesekethe": Uma i-transformer ene-iron core isebenza ku-unsaturated core, ukufinyeleleka kwayo kazibuthe kukhulu, ngakho-ke i-inductance inkulu, futhi ukulahlekelwa okuyisisekelo akunakwa, cishe kungathathwa njengento efanelekile. i-transformer.
Ake sibheke isiphetho sakhe futhi. “Ku-transformer ekahle, amandla amuncwa ukujikajika okuyinhloko ngu-u1i1, futhi amandla amuncwa ukujikajika kwesibili ngu-u2i2=-u1i1, okusho ukuthi, amandla okufaka ohlangothini oluyinhloko lwe-transformer aphuma emthwalweni ngokusebenzisa uhlangothi lwesibili. Amandla aphelele amuncwa i-transformer ayi-zero, ngakho-ke i-transformer ekahle iyisici esingagcini amandla noma sisebenzise amandla.
” Yiqiniso, abanye abangani baphinde bathi kumjikelezo we-flyback, i-transformer ingagcina amandla. Eqinisweni, ngihlole ulwazi futhi ngathola ukuthi i-transformer yayo ephumayo inomsebenzi wokugcina amandla ngaphezu kokufeza ukuhlukaniswa kukagesi kanye nokufanisa i-voltage.Owokuqala uyimpahla ye-transformer, kanti lena yokugcina iyimpahla ye-inductor.Ngakho-ke, abanye abantu bayibiza ngokuthi i-inductor transformer, okusho ukuthi ukugcinwa kwamandla empeleni kuyimpahla ye-inductor.
2. Izici zama-transformer ekusebenzeni kwangempela
Kunenani elithile lesitoreji samandla ekusebenzeni kwangempela. Ku-transformers wangempela, ngenxa yezici ezifana nokuvuza kwamagnetic, ukulahlekelwa kwethusi nokulahlekelwa kwensimbi, i-transformer izoba nenani elithile lokugcina amandla.
I-iron core ye-transformer izokhiqiza ukulahlekelwa kwe-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy ngaphansi kwesenzo se-alternating magnetic field. Lokhu kulahlekelwa kuzodla ingxenye yamandla ngendlela yamandla okushisa, kodwa futhi kuzobangela inani elithile lamandla kazibuthe ukuthi ligcinwe kumongo wensimbi. Ngakho-ke, lapho i-transformer isetshenziswa noma inqanyulwa, ngenxa yokukhululwa noma ukugcinwa kwamandla kazibuthe ku-core iron, i-overvoltage yesikhathi esifushane noma into yokuhlinzwa ingase yenzeke, okubangela umthelela kwezinye izinto zokusebenza ohlelweni.
3. Izici zokugcina amandla e-Inductor
Lapho i-current in the circuit iqala ukwanda, iinductorizophazamisa ukushintshwa kwamandla. Ngokomthetho wokungeniswa kwe-electromagnetic, amandla e-electromotive azenzelayo akhiqizwa kuzo zombili iziphetho ze-inductor, futhi isiqondiso sawo siphambene nesiqondiso soshintsho lwamanje. Ngalesi sikhathi, ukunikezwa kwamandla kudinga ukunqoba amandla e-electromotive azidalayo ukuze enze umsebenzi futhi aguqule amandla kagesi abe amandla kazibuthe ku-inductor ukuze agcinwe.
Lapho i-current ifinyelela esimweni esizinzile, inkambu kazibuthe ku-inductor ayisashintshi, futhi amandla e-electromotive azenzela wona anguziro. Ngalesi sikhathi, nakuba i-inductor ingasawamumbi amandla kugesi, isawagcina amandla kazibuthe agcinwe ngaphambili.
Lapho i-current in circuit iqala ukwehla, insimu yamagnetic ku-inductor izophinde ibe buthakathaka. Ngokomthetho wokungeniswa kwe-electromagnetic, i-inductor izokhiqiza amandla e-electromotive azenzelayo endaweni efanayo nokuncipha kwamanje, izama ukugcina ubukhulu bamanje. Kule nqubo, amandla kazibuthe agcinwe ku-inductor aqala ukukhululwa futhi aguqulwe abe amandla kagesi ukuze abuyele kumjikelezo.
Ngenqubo yayo yokugcina amandla, singamane siqonde ukuthi uma kuqhathaniswa ne-transformer, inokufakwa kwamandla kuphela futhi akukho okukhipha amandla, ngakho-ke amandla agcinwa.
Okungenhla kuwumbono wami siqu. Ngethemba ukuthi kuzosiza bonke abaklami bamabhokisi aguquguqukayo aphelele ukuze baqonde ama-transformer nama-inductors! Ngingathanda futhi ukwabelana nawe ngolwazi lwesayensi:ama-transformers amancane, ama-inductors, nama-capacitor ahlakazwe ezintweni zikagesi zasendlini kufanele akhishwe ngaphambi kokuthintwa noma kulungiswe ochwepheshe ngemva kokuhamba kukagesi!
