Asebenza Kanjani Ama-Power Transformers?
Ama-Power transformer adlulisa amandla kagesi ngokusebenzisa inkambu kazibuthe eshintshayo. I-voltage eshintshanayo esetshenziswa ekujikeni okukodwa isungula i-flux kazibuthe eshintshanayo, eyenza i-voltage kwenye i-wiring exhunywe yilokho kugeleza. Uma umthwalo uxhunyiwe, ukugeleza kwamanje kumjikelezo wokuphumayo futhi i-transformer idonsa amandla okufaka ahambisanayo, kanye nokulahlekelwa kwayo.
Ubudlelwano bamajika obumangelengele bunquma isilinganiso esiyisisekelo se-voltage. Ayiwakhi amandla engeziwe. Le ncazelo isebenzisa i-AC evamile, i-transformer enamawindi amabili njengesiqalo sayo; imiklamo engokoqobo yengeza ukwahlukanisa, ukupholisa kanye nezinye izici ukuze kugcinwe leyo nqubo ngaphakathi kwemingcele kagesi neyokushisa yezinto zokusebenza.
I-Alternating Voltage Idala I-Magnetic Flux
I-winging exhunywe emthonjeni ibizwa ngokuthi i-primary winding. Lapho i-AC voltage isetshenziswa, i-magnetic flux iyashintsha ngokuqhubekayo. Ku-transformer evamile, ingqikithi kazibuthe inikeza indlela exhumanisa ama-windings futhi isekele ukuhlangana kwawo kwe-electromagnetic.
Ukulandelana kulula ukukuqonda njengenqubo: I-voltage ye-AC isetshenziswa kweyinhloko, i-flux eshintshashintshayo ixhumanisa ama-windings, futhi i-voltage ifakwa kwesesibili. Lezi yimiphumela kagesi exhunyiwe, hhayi izenzo zemishini ezihlukene. Ayikho i-generator ejikelezayo ngaphakathi kwesiguquli samandla esivamile.
Indima yomgogodla inguzibuthe. Akuyona intambo ethwala i-primary current kusekethe yesibili. Ku-transformer evamile enamawindi ahlukene, amandla adluliswa ngokuhlanganiswa kazibuthe kuyilapho isistimu yokuhlukanisa ihlinzeka ngokuhlukana okuklanyiwe phakathi kwamasekhethi.
Indlela I-Voltage Eyenziwe Ngayo Komunye Umoya
I-winding exhunywe ngokushintsha i-flux kazibuthe idala i-voltage eyenzelwe. Ngakho-ke i-winding yesibili ine-voltage kumatheminali ayo ngisho nangaphambi kokuba umthwalo wangaphandle udonse amandla kuwo. Ukuxhuma umthwalo ofanele kuqeda isifunda esikhiphayo futhi kuvumela i-transformer ukuthi inikeze amandla kulowo mthwalo.
Lo mehluko wehlukanisa i-voltage kumandla alethiwe. Isesibili esinamandla esingenawo umthwalo oxhunyiwe singaba ne-voltage ekhona ngaphandle kokuletha amandla awusizo okulayisha. Akumele kuthathwe njengokuphephile ngenxa nje yokuthi akukho mshini noma isekethe edonsa amanzi.
“Okuyinhloko” kanye “nokwesibili” kuhlonza indima yokufaka neyokukhiphayo encazelweni. Azisho ngokuzenzakalelayo i-voltage ephezulu kanye ne-low voltage. Kuhlelo lokusebenza lokukhuphuka, i-winding yokufaka isebenza ku-voltage ephansi; ohlelweni lokuya phansi, lusebenza ku-voltage ephezulu.
Ukuthi I-turns Ratio Ishintsha kanjani i-Voltage
Kumodeli ekahle enamawindi amabili, isilinganiso samandla kagesi ajikajikayo silandela isilinganiso sokuphenduka:
V2 /V1 =N2 /N1
V1 futhi V2 ama-voltages aqala kanye nawesibili okujikajika; N1 kanye no-N2 izinombolo ezihambisanayo zamajika. Ukuphenduka okwengeziwe kwesibili kunikeza i-voltage yesibili ephezulu. Ukujika kwesibili okumbalwa kunikeza i-voltage ephansi.
Ukuze uthole i-transformer ekahle engokomfanekiso, isilinganiso esingu-2:1 sokuphenduka okuyisisekelo ukuya kwesesibili sizonciphisa okungu-200 V kumjikelezo oyisisekelo siye ku-100 V ngaphesheya kwesibili. Lesi isibonelo sokufundisa, hhayi isilinganiso somkhiqizo we-JSGK noma isincomo sedizayini.
