Kodi Kusiyana Pakati pa AC ndi DC N'chiyani?

Monga gawo lofunika kwambiri mu gridi yamagetsi, Zosinthira Mphamvu Ndiwo maziko a momwe timagawira ndi kugwiritsa ntchito magetsi. Koma magetsi omwe amayenda kudzera mu ma transformer awa amabwera m'njira ziwiri zazikulu: Alternating Current (AC) ndi Direct Current (DC). Kumvetsetsa kusiyana ndikofunikira kwambiri kuti timvetsetse machitidwe amagetsi amakono.

Pa[Bungwe la Zaumoyo wa Anthu Onse], katswiri muchosinthira mphamvuPakupanga, timagwiritsa ntchito mphamvu ya AC tsiku lililonse. Munkhaniyi, tifotokoza momveka bwino kusiyana pakati pa AC ndi DC, chifukwa chake AC inakhala muyezo wa ma gridi amagetsi, komanso komwe DC ndi yofunika kwambiri.

Kusiyana Kwakukulu: Kufanizira Kosavuta

Tangoganizirani momwe magetsi akuyendera ngati madzi omwe akuyenda mu chitoliro.

 

Mphamvu Yolunjika (DC)ali ngati madzi akuyendamokhazikika komanso mosalekeza mbali imodzipansi pa chitoliro chowongoka. Ndi chinthu chodziwikiratu komanso chofanana.

Mphamvu Yosinthira (AC)ali ngati madzikuthamanga mofulumira mozunguliramu chitoliro. Kuyenda kwa ukonde kuli zero, koma mphamvu ikupititsidwabe kudzera mu kuyendako.

 

Kusiyana kwakukulu kumeneku munjira yoyenderandiye maziko a AC ndi DC.

 

 

Kuyerekeza Mbali ndi Mbali: AC vs. DC

 

 

Kuzama Kwambiri mu Kusiyana Kofunika Kwambiri

1. Kuyenda ndi Kutsogolera kwa Panopa

DC:Chinsinsi apa ndiMwachindunjiMphamvu yamagetsi imayenda mbali imodzi, yosagwedezeka kuchokera ku positive kupita ku negative terminal. Taganizirani za tochi yoyendetsedwa ndi batri; mphamvuyo imayenda molunjika kuchokera ku batri kupita ku babu.

NDI:Chinsinsi apa ndiKusinthanaMphamvu yamagetsi nthawi ndi nthawi imatembenuza njira. Mu machitidwe ambiri amagetsi, izi zimachitika nthawi 50 kapena 60 pa sekondi (yomwe imayesedwa ngati Hertz, Hz). Izi zikutanthauza kuti ma elekitironi omwe ali mu waya wa nyumba yanu akugwedezeka mobwerezabwereza nthawi 60 pa sekondi, osayenda mozungulira mosalekeza.

2. "Nkhondo ya Mitsinje" ndi Chifukwa Chake AC Yapambana pa Kutumiza kwa Gridi

Izi si mbiri chabe; ndi chifukwa chachikulu chomwe gridi yathu yamagetsi imamangidwa pa AC, ndipo chifukwa chake, chifukwa chakema transformer amphamvundi otsutsa kwambiri.

Kumapeto kwa zaka za m'ma 1800, Thomas Edison adapambana mpikisano wa DC, pomwe Nikola Tesla ndi George Westinghouse adapambana mpikisano wa AC. AC idapambana "Nkhondo ya Currents" pachifukwa chimodzi chachikulu:kusinthika.

Vuto ndi Kutumiza DC:Magetsi akamayenda mtunda wautali, amakumana ndi kukana kwa mawaya, zomwe zimapangitsa kuti magetsi awonongeke chifukwa cha kutentha. Kuti muchepetse kutayika kumeneku, muyenera kutumiza mphamvu pa nthawi yoyenera.mphamvu yamagetsi yapamwambakenako "tsikirani pansi" ku mphamvu yotetezeka komanso yotsika ya magetsi m'nyumba ndi mabizinesi.

Cholakwika Chachikulu cha DC:Mu zaka za m'ma 1880, panalibe njira yothandiza komanso yotsika mtengo yowonjezerera kapena kuchepetsa mphamvu ya DC.

Ubwino Wopambana wa AC:Mphamvu yamagetsi ya AC imatha kuwonjezeka mosavuta (kukwera mmwamba) ndi kuchepetsedwa (kutsika pang'onopang'ono) pogwiritsa ntchito chipangizo chotchedwatransformer.

Apa ndi pomwe ukatswiri wathu umayambira.Ma transformer amagetsiPa malo opangira magetsi, magetsi a AC amakwera kufika pamlingo wapamwamba kwambiri (monga ma volts 400,000 kapena kuposerapo) kuti magetsi azitha kuyenda bwino mtunda wautali popanda kutayika kwambiri. Kenako, pa malo ocheperako omwe ali pafupi ndi madera okhala anthu ambiri, ma transformer ena amatsitsa magetsi kufika pa 120/240V yomwe timagwiritsa ntchito m'nyumba zathu.

Mphamvu yosavuta iyi yosinthira magetsi ndiyo chifukwa chake AC inakhala muyezo wosatsutsika wa ma gridi amagetsi padziko lonse lapansi.

3. Ntchito Zamakono: Kumene Chilichonse Chimawala

Ngakhale kuti AC ndiye imalamulira gridi, DC si yakale kwenikweni. Mtundu uliwonse umachita bwino kwambiri m'dera lake:

AC ndi yabwino kwambiri pa:

Kulimbikitsa mizinda yonse ndi nyumba.

Ma injini ndi makina a mafakitalezomwe ndi zosavuta komanso zodalirika kwambiri pa AC.

Mapulogalamu amphamvu kwambirimonga kutentha ndi magetsi.

DC ndi yofunika kwambiri pa:

Zamagetsi:Foni yanu, laputopu, TV, ndi zipangizo zonse za digito zimagwira ntchito mkati mwa DC. Ichi ndichifukwa chake ma adapter awo amphamvu (kapena "ma charger") ndi ma converter a AC-to-DC.

 

Mabatire:Mabatire onse (kuphatikizapo omwe ali mu ma EV) amasunga ndi kupereka mphamvu ya DC.

 

Mphamvu ya Dzuwa:Ma solar panels amapanga magetsi a DC, zomwe zimafuna inverter kuti isinthe kukhala AC kuti igwiritsidwe ntchito kunyumba.

 

Magalimoto Amagetsi:Mabatire a EV amagwiritsa ntchito DC, ndipo malo ochaja mwachangu a DC akukhala muyezo.

 

Mapeto: Mgwirizano Wogwirizana

Kusiyana pakati pa AC ndi DC sikuti ndi komwe kuli bwino; koma ndi komwe kuli koyenera pantchitoyo. Dziko lathu lamakono limadalira mgwirizano wamakono pakati pa awiriwa.

 

ACndiye ngwazi yakutumiza ndi kugawa mphamvu pa mtunda wautali, othandizidwa ndi odzichepetsa koma ofunikirachosinthira mphamvu.

 

DCndiye ngwazi yamalo osungira mphamvu ndi zamagetsi a digitozomwe zimalimbitsa moyo wathu wa tsiku ndi tsiku.

 

PaBungwe la Zaumoyo wa Anthu OnseNdife akatswiri pankhani ya AC ya mgwirizanowu. Timapanga ndi kupanga zinthu zodalirika.ma transformer amphamvuzomwe zimapanga maziko a zomangamanga zamagetsi, kuonetsetsa kuti mphamvu ya AC yopangidwa pafakitale ikuperekedwa bwino komanso mosamala pakhomo panu.
