Empilweni yethu yansuku zonke, sidinga ukusebenzisa ugesi nsuku zonke, futhi asijwayelene nogesi oqondile kanye nogesi oshintshanayo, isibonelo, ugesi ophumayo webhethri ugesi oqondile, kanti ugesi wasekhaya nowezimboni ugesi oshintshanayo, ngakho-ke uyini umehluko phakathi kwalezi zinhlobo ezimbili zikagesi?
“Ugesi oqondile”, owaziwa nangokuthi “ugesi oqhubekayo”, ugesi oqhubekayo uwuhlobo lwamandla aqondile, usayizi wamanje kanye nesiqondiso akushintshi ngokuhamba kwesikhathi.
Ukushintshana kwamandla kagesi
Ukushintshana kwamandla kagesi (i-AC)ingumbane osayizi wawo kanye nesiqondiso sawo kushintsha njalo, futhi ubizwa ngokuthi umbane oshintshanayo noma umane ushintshanayo ngoba inani elimaphakathi lombane ophindaphindayo emjikelezweni owodwa lingu-zero.
Indlela iyafana yemisinga eqondile ehlukene. Ngokuvamile i-waveform iyi-sinusoidal. I-alternating current ingadlulisa ugesi kahle. Kodwa-ke, kunezinye izinhlobo zamagagasi ezisetshenziswayo, njengamagagasi angunxantathu namagagasi ayisikwele.
Ukwehlukaniswa
1. Isiqondiso: Ku-direct current, isiqondiso samandla kagesi sihlala sifana, sigeleza ohlangothini olulodwa. Ngokuphambene nalokho, isiqondiso samandla kagesi ekushintsheni kwamandla kagesi sishintsha njalo, sishintshana phakathi kwesiqondiso esihle nesingesihle.
2. Izinguquko ze-voltage: I-voltage ye-DC ihlala ingaguquki futhi ayishintshi ngokuhamba kwesikhathi. I-voltage ye-alternating current (AC), ngakolunye uhlangothi, i-sinusoidal ngokuhamba kwesikhathi, futhi imvamisa ivame ukuba yi-50 Hz noma i-60 Hz.
3. Ibanga lokudlulisa: I-DC inokulahlekelwa kwamandla okuncane ngesikhathi sokudlulisa futhi ingadluliselwa emabangeni amade. Ngenkathi amandla e-AC ekudlulisweni kwebanga elide azolahlekelwa amandla amakhulu, ngakho-ke kudingeka alungiswe futhi abuyiselwe nge-transformer.
4. Uhlobo lokunikezwa kwamandla: Imithombo yamandla evamile ye-DC ifaka amabhethri namaseli elanga, njll. Le mithombo yamandla ikhiqiza amandla kagesi e-DC. Ngenkathi amandla e-AC evame ukukhiqizwa yizitshalo zamandla futhi anikezwa ngama-transformer kanye nemigqa yokudlulisela ukusetshenziswa kwasekhaya nasezimbonini.
5. Izindawo zokusetshenziswa: I-DC ivame ukusetshenziswa emishinini kagesi, ezimotweni zikagesi,Iziteshi Zokushaja I-EV, njll. I-AC isetshenziswa kabanzi ezisetshenziswa zasekhaya. I-Alternating current (AC) isetshenziswa kabanzi ekugesini kwasekhaya, ekukhiqizweni kwezimboni, nasekudlulisweni kwamandla.
6. Amandla wamanje: Amandla wamanje we-AC angahluka ngemijikelezo, kanti amandla e-DC avame ukuhlala engaguquki. Lokhu kusho ukuthi ngamandla afanayo, amandla wamanje we-AC angaba makhulu kunalawo e-DC.
7. Imiphumela kanye nokuphepha: Ngenxa yokwehluka kwendlela yamanje kanye ne-voltage yamandla ashintshanayo, kungabangela imisebe kagesi, imiphumela ye-inductive kanye ne-capacitive. Le miphumela ingaba nomthelela ekusebenzeni kwemishini kanye nempilo yabantu ngaphansi kwezimo ezithile. Ngokuphambene nalokho, amandla e-DC awanazo lezi zinkinga ngakho-ke ayathandwa emishinini ethile ebucayi noma ekusetshenzisweni okuthile.
8. Ukulahlekelwa Kokudlulisela: Amandla e-DC anokulahlekelwa kwamandla okuphansi uma edluliselwa emabangeni amade ngoba awathintwa ukumelana nokungena kwamandla e-AC. Lokhu kwenza i-DC isebenze kahle kakhulu ekudluliseni nasekudluliseni amandla emabangeni amade.
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-inverter, abalawuli bamandla kagesi, njll.), ngakolunye uhlangothi, ngokuvamile kubiza kakhulu. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe be-DC, izindleko zemishini ye-DC ziyehla kancane kancane.
