Uyini Umehluko Phakathi Kwe-AC Ne-DC?

Njengengxenye eyinhloko kugridi kagesi, Ama-Power Transformers ziyisisekelo sendlela esasabalalisa futhi sisebenzise ngayo ugesi. Kodwa ugesi ogeleza ngalezi ziguquli uza ngezindlela ezimbili eziyinhloko: Ukushintshana Kwamanje (AC) kanye Nokuqondile Kwamanje (DC). Ukuqonda umehluko kubalulekile ekuqondeni izinhlelo zamandla zesimanje.

Ku-[I-ejensi Yezempilo Yomphakathi], uchwepheshe kuisiguquli samandlaEkukhiqizeni, sibhekana namandla e-AC nsuku zonke. Kulesi sihloko, sizochaza ngokucacile umehluko phakathi kwe-AC ne-DC, ukuthi kungani i-AC yaba yindinganiso yamagridi kagesi, nokuthi i-DC ibaluleke kakhulu kuphi.

Umehluko Omkhulu: Isifaniso Esilula

Cabanga ngokugeleza kukagesi njengamanzi ageleza epayipini.

 

I-Direct Current (DC)kufana namanzi agelezakancane kancane futhi njalo ohlangothini olulodwaphansi ngepayipi eliqondile. Kubikezelwa futhi kuyafana.

I-Alternating Current (AC)kufana namanziukushesha emuva naphambili ngesigqiepayipini. Ukunyakaza kwenetha kungu-zero, kodwa amandla asadluliselwa ngokunyakaza.

 

Lo mehluko oyisisekelo ku-isiqondiso sokugelezayiwona mqondo we-AC ne-DC.

 

 

Ukuqhathaniswa Kohlangothini: I-AC vs. I-DC

 

 

Ukujula Ngokujulile Ezinhlotsheni Eziyinhloko

1. Ukugeleza Kwamanje kanye Nesiqondiso

I-DC:Isihluthulelo laphaOkuqondileIshaja kagesi igeleza ngendlela eyodwa, engaguquki isuka endaweni enhle iye endaweni engeyinhle. Cabanga ngethoshi elisebenzisa ibhethri; amandla ageleza ngqo esuka ebhethri aye ebhalbhu.

FUTHI:Isihluthulelo laphaUkushintshana. Ukushaja kukagesi kuguqula indlela ngezikhathi ezithile. Ezinhlelweni eziningi zamandla, lokhu kwenzeka izikhathi ezingu-50 noma ezingu-60 ngomzuzwana (kulinganiswa njenge-Hertz, Hz). Lokhu kusho ukuthi ama-electron asezintambo zasekhaya lakho ayadlidliza emuva naphambili izikhathi ezingu-60 ngomzuzwana, awahambi ngendlela eqhubekayo.

2. "Impi Yama-Currents" kanye Nesizathu Sokuthi I-AC Iwine Ekudlulisweni Kwegridi

Lokhu akuyona nje umlando; yisona sizathu esiyinhloko esenza igridi yethu yamandla yakhelwe ku-AC, futhi ngenxa yalokho, yingakhoama-transformer kagesizigxeka kakhulu.

Ngasekupheleni kwekhulu le-19, uThomas Edison walwela i-DC, kanti uNikola Tesla noGeorge Westinghouse balwela i-AC. I-AC yanqoba "iMpi Yama-Currents" ngesizathu esisodwa esiyinhloko:ukuguqulwa.

Inkinga Ngokudluliswa Kwe-DC:Uma ugesi uhamba amabanga amade, ubhekana nokumelana ezintanjeni, okubangela ukulahlekelwa ugesi njengokushisa. Ukuze unciphise lokhu kulahlekelwa, udinga ukudlulisa ugesi ngesikhathi esifanele.i-voltage ephezulubese "wehla" uye ku-voltage ephephile nephansi yamakhaya namabhizinisi.

Iphutha Elibulalayo le-DC:Ngawo-1880, kwakungekho ndlela ephumelelayo neyongayo yokwandisa noma yokunciphisa i-DC voltage.

Inzuzo Yokuwina ye-AC:I-voltage ye-AC ingakhushulwa kalula (inyuswe) futhi yehliswe (inyuswe) kusetshenziswa idivayisi ebizwa ngokuthi i-i-transformer.

Yilapho ubuchwepheshe bethu bungena khona.Ama-transformer kagesieziteshini ezikhiqizayo nyusa i-voltage ye-AC iye emazingeni aphezulu kakhulu (njengama-volt angu-400,000 noma ngaphezulu) ukuze kudluliselwe kahle ibanga elide futhi kube nokulahlekelwa okuncane. Bese kuthi, eziteshini ezincane eziseduze nezindawo ezinabantu abaningi, amanye ama-transformer ehlise i-voltage iye ku-120/240V esiyisebenzisayo emakhaya ethu.

Leli khono elilula lokuguqula i-voltage yingakho i-AC yaba yindinganiso engenakuphikiswa yamagridi kagesi omhlaba.

3. Izicelo Zanamuhla: Lapho Ngayinye Ikhanya Khona

Nakuba i-AC ibusa igridi, i-DC ayisasebenzi nhlobo. Uhlobo ngalunye luhamba phambili endaweni yalo:

I-AC ilungele kakhulu:

Ukunika amandla amadolobha nemizi yonke.

Izimoto nemishini yezimboniokulula futhi okuthembekile kakhulu ku-AC.

Izinhlelo zokusebenza ezinamandla aphezulunjengokushisa nokukhanyisa.

I-DC ibalulekile ku:

Izinto zikagesi:Ifoni yakho, i-laptop, i-TV, kanye nawo wonke amadivayisi edijithali asebenza ngaphakathi ku-DC. Yingakho ama-adapter abo kagesi (noma "amashaja") empeleni engabaguquli be-AC-to-DC.

 

Amabhethri:Wonke amabhethri (kufaka phakathi lawo akwi-EV) agcina futhi anikeze amandla e-DC.

 

Amandla Elanga:Amaphaneli elanga akhiqiza ugesi we-DC, okudinga i-inverter ukuze iwuguqulele ku-AC ukuze usetshenziswe ekhaya.

 

Izimoto Zikagesi:Amabhethri e-EV asebenzisa i-DC, kanti iziteshi zokushaja okusheshayo ze-DC seziba yizindinganiso.

 

Isiphetho: Ubambiswano Olubambisene

Umehluko phakathi kwe-AC ne-DC awukona ukuthi yikuphi okungcono; kodwa ukuthi yikuphi okulungile emsebenzini. Izwe lethu lanamuhla lithembele ekubambisaneni okuyinkimbinkimbi phakathi kwalokhu okubili.

 

I-ACungumpetha weukudluliswa kwamandla ebanga elide kanye nokusatshalaliswa kwawo, enikwe amandla yilabo abathobekile kodwa ababalulekileisiguquli samandla.

 

I-DCungumpetha weisitoreji samandla kanye ne-elekthronikhi yedijithaliezinika amandla izimpilo zethu zansuku zonke.

 

Ku-I-ejensi Yezempilo Yomphakathi, singochwepheshe ohlangothini lwe-AC lwalobu budlelwano. Siklama futhi sikhiqiza ngendlela ethembekileama-transformer kagesiezakha umgogodla wengqalasizinda kagesi, okuqinisekisa ukuthi amandla e-AC akhiqizwa esitshalweni alethwa kahle nangokuphephile emnyango wakho.
