Uyini ngempela umehluko phakathi kwe-AC ne-DC?

Ekuphileni kwethu kwansuku zonke, kudingeka sisebenzise ugesi nsuku zonke, futhi asijwayelene namandla aqondile kanye ne-alternating current, isibonelo, ukukhishwa kwamanje kwebhethri kungokuqondile, kuyilapho ugesi wasendlini kanye nowezimboni ushintshashintsha, ngakho-ke yini umehluko phakathi kwalezi zinhlobo ezimbili zikagesi?

Amanje aqondile

"Direct current", eyaziwa nangokuthi "constant current", i-current current iwuhlobo lwamanje oluqondile, ubukhulu bamanje kanye nesiqondiso akushintshi ngokuhamba kwesikhathi.
Ishintshana yamanje

I-alternating current (AC)imanje ubukhulu bayo nendlela eshintsha ngayo ngezikhathi ezithile, futhi ibizwa ngokuthi imanje eshintshanayo noma imanje eshintshanayo ngenxa yokuthi inani elimaphakathi lamanje lenkathi ethile kumjikelezo owodwa linguziro.
Isiqondiso siyafana emisinga eqondile ehlukene.Ngokuvamile i-waveform i-sinusoidal.Ukushintshana kwamandla kungadlulisa ugesi ngendlela efanele.Kodwa-ke, akhona amanye amagagasi asetshenziswayo ngempela, njengamagagasi angunxantathu namagagasi ayisikwele.

Umehluko

1. Isiqondiso: Esikhathini samanje esiqondile, isiqondiso samanje sihlala sifana, sigeleza ohlangothini olulodwa.Ngokuphambene, isiqondiso samanje ekushintsheni kwamanje sishintsha ngezikhathi ezithile, sishintshana phakathi kwezikhombisi-ndlela ezinhle nezingezinhle.

2. Izinguquko zamandla kagesi: I-voltage ye-DC ihlala ingashintshi futhi ayishintshi ngokuhamba kwesikhathi.I-voltage ye-alternating current (AC), ngakolunye uhlangothi, i-sinusoidal ngokuhamba kwesikhathi, futhi imvamisa ngokuvamile i-50 Hz noma i-60 Hz.

3. Ibanga lokudlulisela: I-DC inokulahlekelwa kwamandla amancane ngesikhathi sokudlulisela futhi ingadluliselwa ebangeni elide.Ngenkathi amandla e-AC ekudlulisweni kwebanga elide azolahlekelwa amandla amakhulu, ngakho-ke kudingeka alungiswe futhi anxeshezelwe nge-transformer.

4. Uhlobo lokunikezwa kwamandla: Imithombo yamandla evamile ye-DC ihlanganisa amabhethri namaseli elanga, njll. Le mithombo yamandla ikhiqiza i-DC current.Nakuba amandla e-AC ngokuvamile akhiqizwa izitshalo zikagesi futhi ahlinzekwa ngama-transformer nezintambo zokudlulisa ukuze zisetshenziswe ezindlini nasezimbonini.

5. Izindawo zokufaka isicelo: I-DC ijwayele ukusetshenziswa emishinini kagesi, ezimotweni zikagesi,izinhlelo zamandla elanga, njll. I-AC isetshenziswa kakhulu ezinhlelweni zasendlini.I-alternating current (AC) isetshenziswa kakhulu kugesi wasendlini, ukukhiqizwa kwezimboni, kanye nokudluliswa kwamandla.

6. Amandla amanje: Amandla amanje e-AC angahluka ngemijikelezo, kuyilapho awe-DC ngokuvamile ahlala engashintshi.Lokhu kusho ukuthi ngamandla afanayo, amandla amanje e-AC angaba makhulu kunalawo e-DC.

7. Imithelela nokuphepha: Ngenxa yokuhluka kwendlela yamanje kanye ne-voltage yamanje ashintshayo, kungase kubangele imisebe kazibuthe, imiphumela eguquguqukayo kanye ne-capacitive.Le miphumela ingase ibe nomthelela ekusebenzeni kwemishini kanye nempilo yomuntu ngaphansi kwezimo ezithile.Ngokuphambene, amandla e-DC awanazo lezi zinkinga ngakho-ke ancanyelwa izinto ezithile ezibucayi noma izinhlelo zokusebenza ezithile.

8. Ukulahleka Kokudlulisa: Amandla e-DC anokulahleka kwamandla aphansi uma edluliswa ebangeni elide ngoba awathintwa ukumelana nokungena kwamandla e-AC.Lokhu kwenza i-DC isebenze kahle kakhulu ekudluliseni amabanga amade nokudluliswa kwamandla.

9. Izindleko zemishini: Imishini ye-AC (isb., ama-transformer, ama-generator, njll.) ivame kakhulu futhi ivuthiwe, ngakho-ke izindleko zayo ziphansi kakhulu.Imishini ye-DC (isb,ama-inverters, izilawuli zamandla kagesi, njll.), ngakolunye uhlangothi, ngokuvamile zibiza kakhulu.Kodwa-ke, ngokuthuthukiswa kobuchwepheshe be-DC, izindleko zemishini ye-DC ziyancipha kancane kancane.
