Yintoni kanye kanye umahluko phakathi kwe-AC kunye ne-DC?

Kubomi bethu bemihla ngemihla, kufuneka sisebenzise umbane yonke imihla, kwaye asiqhelekanga ngoku ngokuthe ngqo kunye nokutshintshisana ngoku, umzekelo, imveliso yangoku yebhetri ikhoyo ngoku, ngelixa umbane wendlu kunye nombane wemizi-mveliso utshintshana ngoku, ngoko yintoni na. Ngaba umahluko phakathi kwezi ntlobo zimbini zombane?

Ngqo ngoku

"Umsinga othe ngqo", owaziwa ngokuba yi "constant current", umsinga oqhubekayo luhlobo oluthile lwangoku ngokuthe ngqo, ubukhulu bangoku kunye nolwalathiso alutshintshi kunye nexesha.
Ukutshintshana kwangoku

Ukutshintshana kwangoku (AC)ngumsinga otshintsha ubungakanani kunye nomkhombandlela ngamaxesha athile, kwaye ubizwa ngokuba ngumsinga otshintshanayo okanye umsinga otshintshayo kuba umndilili wexabiso langoku kumjikelo omnye nguziro.
Isalathiso siyafana kwimisinga ethe ngqo eyahlukeneyo.Ngokuqhelekileyo i-waveform i-sinusoidal.Ukutshintshana kwangoku kunokuhambisa umbane ngokufanelekileyo.Nangona kunjalo, kukho ezinye iifom zamaza ezisetyenziswa ngokwenene, njengamaza angama-triangular kunye namaza angama-square.

Umahluko

1. Ulwalathiso: Ngokuthe ngqo, ulwalathiso lwangoku luhlala lufana, luhamba ngendlela enye.Ngokwahlukileyo, isalathiso sangoku ekutshintsheni utshintsho lwangoku ngamaxesha, lutshintshana phakathi kweendlela ezilungileyo nezingalunganga.

2. Ukutshintsha kwamandla ombane: I-voltage ye-DC ihlala ingatshintshi kwaye ayitshintshi ngokuhamba kwexesha.I-voltage ye-alternating current (AC), ngakolunye uhlangothi, i-sinusoidal ngokuhamba kwexesha, kwaye i-frequency i-50 Hz okanye i-60 Hz.

3. Umgama wothumelo: I-DC inelahleko encinci yamandla ngexesha lothumelo kwaye inokudluliselwa kumgama omde.Ngelixa amandla e-AC kumgama omde aya kuba nelahleko enkulu yamandla, ngoko ke kufuneka ahlengahlengiswe kwaye abuyekezwe nge-transformer.

4. Uhlobo lonikezelo lwamandla: Imithombo yamandla eqhelekileyo ye-DC ibandakanya iibhetri kunye neeseli zelanga, njl njl. Le mithombo yamandla ivelisa i-DC yangoku.Ngelixa amandla e-AC edla ngokuveliswa zizityalo zombane kwaye abonelelwe ngeenguqu kunye neentambo zothumelo kusetyenziso lwasekhaya nakwimizi-mveliso.

5. Iindawo zesicelo: I-DC isetyenziswa ngokuqhelekileyo kwizixhobo zombane, izithuthi zombane,iinkqubo zamandla elanga, njl njl. I-AC isetyenziswa ngokubanzi kwizicelo zendlu.I-alternating current (AC) isetyenziswa kakhulu kumbane wasekhaya, imveliso yemizi-mveliso, kunye nokuhanjiswa kwamandla.

6. Amandla angoku: Amandla akhoyo e-AC anokwahluka kwimijikelo, ngelixa i-DC ihlala ihlala ingatshintshi.Oku kuthetha ukuba kumandla afanayo, amandla akhoyo e-AC anokuba makhulu kunalawo e-DC.

7. Iziphumo kunye nokhuseleko: Ngenxa yeeyantlukwano kwicala langoku kunye nombane wombane otshintshayo wangoku, inokubangela imitha ye-electromagnetic radiation, inductive kunye ne-capacitive effects.Ezi ziphumo zinokuba nefuthe ekusebenzeni kwezixhobo kunye nempilo yabantu phantsi kweemeko ezithile.Ngokwahlukileyo, amandla eDC akanazo ezi ngxaki kwaye ke ngoko akhethwa kwisixhobo esithile esibuthathaka okanye usetyenziso oluthile.

8. Ilahleko yoThumelo: Amandla eDC anelahleko ephantsi xa egqithiselwa kumgama omde kuba awachatshazelwa kukuxhathisa kunye nokunyanzeliswa kwamandla e-AC.Oku kwenza i-DC isebenze ngakumbi kuthumelo lomgama omde kunye nokudluliselwa kwamandla.

9. Iindleko zezixhobo: Izixhobo ze-AC (umzekelo, ii-transformers, iijeneretha, njl.) zixhaphake kakhulu kwaye zivuthiwe, kwaye ke ixabiso layo liphantsi.Izixhobo zeDC (umz.,ii-inverters, i-voltage regulators, njl.), kwelinye icala, idla ngokubiza kakhulu.Nangona kunjalo, ngophuhliso lobuchwepheshe be-DC, iindleko zezixhobo ze-DC ziyancipha ngokuthe ngcembe.
