Qhov txawv ntawm AC thiab DC yog dab tsi?

Hluav taws xob siv hluav taws xob los ua lub zog rau peb lub ntiaj teb niaj hnub no, tab sis tsis yog txhua yam hluav taws xob zoo ib yam. Alternating Current (AC) thiab Direct Current (DC) yog ob hom hluav taws xob tseem ceeb, thiab kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau txhua tus neeg uas tab tom tshawb nrhiav cov hauv paus ntawm hluav taws xob lossis cov thev naus laus zis uas siv nws. Tsab xov xwm no piav qhia txog qhov sib txawv ntawm AC thiab DC, lawv cov kev siv, thiab lawv qhov tseem ceeb.

1. Lub ntsiab lus thiab kev ntws

Qhov sib txawv tseem ceeb ntawm AC thiab DC yog nyob rau hauv qhov kev taw qhia ntawm qhov tam sim no ntws:

Tam Sim No Ncaj Qha (DC): Hauv DC, cov hluav taws xob ntws mus rau hauv ib qho kev taw qhia tas mus li. Xav txog cov dej ntws tas mus li los ntawm ib lub yeeb nkab yam tsis hloov nws txoj kev. DC yog hom hluav taws xob uas cov roj teeb tsim tawm, ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob me me xws li xov tooj ntse, teeb ci, thiab laptops.

Hluav Taws Xob Hloov Pauv (AC): AC, ntawm qhov tod tes, nws tig rov qab nws txoj kev ib ntus. Tsis txhob ntws ncaj, nws tig rov qab thiab tig los. Cov hluav taws xob no yog qhov uas muab zog rau feem ntau lub tsev thiab cov lag luam vim nws tuaj yeem xa tau yooj yim mus deb nrog kev poob hluav taws xob tsawg kawg nkaus.

2. Kev Tsim thiab Kev Sib Kis

Kev Tsim Hluav Taws Xob DC: Hluav taws xob DC yog tsim los ntawm cov chaw xws li roj teeb, cov vaj huam sib luag hnub ci, thiab cov tshuab hluav taws xob DC. Cov chaw no muab cov hluav taws xob ntws tas li, ua rau lawv tsim nyog rau cov ntawv thov uas xav tau lub zog ruaj khov thiab txhim khu kev qha.

Kev Tsim Hluav Taws Xob AC: AC yog tsim los ntawm cov alternators hauv cov chaw tsim hluav taws xob. Nws yog tsim los ntawm cov hlau nplaum uas tig hauv cov kauj ntawm cov hlau, tsim cov hluav taws xob uas hloov pauv hauv kev taw qhia. Lub peev xwm ntawm AC hloov mus rau qhov hluav taws xob siab dua lossis qis dua ua rau nws ua haujlwm tau zoo heev rau kev xa mus rau qhov deb heev.

3. Kev Hloov Pauv Hluav Taws Xob

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm AC yog nws qhov sib xws nrog cov transformers, uas tuaj yeem nce lossis txo cov theem voltage raws li qhov xav tau. Kev xa hluav taws xob siab txo qhov poob zog thaum mus ncig deb, ua rau AC yog qhov kev xaiv zoo tshaj plaws rau cov grid fais fab. DC, qhov sib piv, nyuaj dua rau kev nce lossis nqis, txawm hais tias cov thev naus laus zis niaj hnub xws li DC-DC converters tau txhim kho nws qhov kev ywj pheej.

4. Cov ntawv thov

Cov Kev Siv DC: DC feem ntau siv rau hauv cov khoom siv hluav taws xob tsawg thiab cov khoom siv nqa tau. Cov no suav nrog cov khoos phis tawj, teeb pom kev zoo LED, tsheb fais fab, thiab cov tshuab hluav taws xob rov ua dua tshiab. Piv txwv li, cov vaj huam sib luag hnub ci tsim hluav taws xob DC, uas feem ntau yuav tsum tau hloov mus rau AC rau kev siv hauv tsev lossis kev lag luam.

Cov Kev Siv AC: AC siv hluav taws xob rau peb lub tsev, chaw ua haujlwm, thiab kev lag luam. Cov khoom siv xws li lub tub yees, lub tshuab cua txias, thiab TV vam khom AC vim nws ua haujlwm tau zoo rau kev faib hluav taws xob los ntawm cov chaw tsim hluav taws xob hauv nruab nrab.

5. Kev Nyab Xeeb thiab Kev Ua Haujlwm Zoo

Kev Nyab Xeeb: AC cov hluav taws xob siab tuaj yeem ua rau muaj kev phom sij, tshwj xeeb tshaj yog tias tsis siv kom raug, thaum DC cov hluav taws xob qis dua feem ntau muaj kev nyab xeeb dua rau kev siv me me. Txawm li cas los xij, ob qho tib si tuaj yeem ua rau muaj kev pheej hmoo yog tias siv tsis raug.

Kev Ua Haujlwm Zoo: DC ua haujlwm tau zoo dua rau kev xa hluav taws xob luv luv thiab cov hluav taws xob hauv hluav taws xob. AC zoo dua rau kev xa mus ntev vim nws cov hluav taws xob poob qis dua ntawm cov hluav taws xob siab. Xaus Lus

Txawm hais tias AC thiab DC ua haujlwm sib txawv, lawv sib pab txhawb nqa ib leeg hauv kev muab lub zog rau peb lub ntiaj teb. AC txoj kev ua haujlwm zoo hauv kev xa hluav taws xob thiab kev siv dav hauv kev tsim kho vaj tse ua rau nws tseem ceeb heev, thaum DC txoj kev ruaj khov thiab kev sib haum xeeb nrog cov thev naus laus zis niaj hnub ua kom nws muaj txiaj ntsig txuas ntxiv. Los ntawm kev nkag siab txog lub zog tshwj xeeb ntawm txhua tus, peb tuaj yeem nkag siab txog lawv ua haujlwm ua ke li cas los ua kom peb lub neej khiav mus zoo.
