Kodi pali kusiyana kotani pakati pa AC ndi DC?

M'moyo wathu watsiku ndi tsiku, tiyenera kugwiritsa ntchito magetsi tsiku ndi tsiku, ndipo sitikudziwa bwino panopa ndi alternating panopa, mwachitsanzo, linanena bungwe la batire panopa mwachindunji panopa, pamene nyumba ndi mafakitale magetsi alternating panopa, kotero chiyani pali kusiyana pakati pa mitundu iwiri ya magetsi?

Direct panopa

"Direct current", yomwe imadziwikanso kuti "constant current", yomwe imakhalapo nthawi zonse ndi mtundu wamakono, ndi kukula kwake ndi kayendetsedwe kake sikumasintha ndi nthawi.
Alternating current

Alternating current (AC)ndi yapano yomwe kukula kwake ndi mayendedwe ake zimasintha nthawi ndi nthawi, ndipo imatchedwa alternating current kapena kungosinthana pang'onopang'ono chifukwa pafupifupi mtengo wanthawi ndi nthawi mumkombero umodzi ndi ziro.
Njirayi ndi yofanana ndi mafunde osiyanasiyana.Kawirikawiri mawonekedwe a waveform ndi sinusoidal.Makina osinthira amatha kutumiza magetsi bwino.Komabe, pali mafunde ena omwe amagwiritsidwa ntchito, monga mafunde a katatu ndi mafunde a square.

Kusiyanitsa

1. Kuwongolera: Pakali pano, mayendedwe apano nthawi zonse amakhalabe ofanana, akuyenda mbali imodzi.Mosiyana ndi izi, mayendedwe apano pakusintha kwapano nthawi ndi nthawi, kusinthasintha pakati pa zabwino ndi zoyipa.

2. Kusintha kwa magetsi: Magetsi a DC amakhalabe osasintha ndipo sasintha pakapita nthawi.Mpweya wa alternating current (AC), kumbali ina, ndi sinusoidal pakapita nthawi, ndipo mafupipafupi amakhala 50 Hz kapena 60 Hz.

3. Mtunda wotumizira: DC imakhala ndi mphamvu zochepa panthawi yopatsirana ndipo imatha kufalikira pamtunda wautali.Ngakhale mphamvu ya AC mumayendedwe akutali idzakhala ndi mphamvu yayikulu yotaya mphamvu, chifukwa chake iyenera kusinthidwa ndikulipidwa kudzera pa thiransifoma.

4. Mtundu wamagetsi: Mphamvu zomwe zimagwiritsidwa ntchito pa DC zimaphatikizapo mabatire ndi ma cell a dzuwa, ndi zina zotere.Ngakhale mphamvu ya AC nthawi zambiri imapangidwa ndi mafakitale amagetsi ndikuperekedwa kudzera mu thiransifoma ndi mizere yopatsirana kuti igwiritsidwe ntchito m'nyumba ndi m'mafakitale.

5. Malo ogwiritsira ntchito: DC imagwiritsidwa ntchito kwambiri pazida zamagetsi, magalimoto amagetsi,machitidwe a mphamvu ya dzuwa, ndi zina zotero. AC imagwiritsidwa ntchito kwambiri pazinthu zapakhomo.Alternating current (AC) imagwiritsidwa ntchito kwambiri pamagetsi apanyumba, kupanga mafakitale, komanso kutumiza magetsi.

6. Mphamvu zamakono: Mphamvu zamakono za AC zimatha kusiyanasiyana mozungulira, pamene DC nthawi zambiri imakhala yosasinthasintha.Izi zikutanthauza kuti mphamvu zomwezo, mphamvu zamakono za AC zikhoza kukhala zazikulu kuposa za DC.

7. Zotsatira ndi chitetezo: Chifukwa cha kusiyanasiyana komwe kulipo komanso mphamvu yamagetsi yamagetsi osinthasintha, zitha kuyambitsa ma radiation a electromagnetic, inductive and capacitive zotsatira.Zotsatirazi zitha kukhala ndi zotsatira pakugwiritsa ntchito zida komanso thanzi la anthu nthawi zina.Mosiyana ndi izi, magetsi a DC alibe mavutowa motero amawakonda pazida zina zodziwika bwino kapena mapulogalamu enaake.

8. Kutaya Kutumiza: Mphamvu ya DC imakhala ndi mphamvu yochepa yotaya mphamvu ikatumizidwa pamtunda wautali chifukwa sichikhudzidwa ndi kukana ndi kulowetsa mphamvu ya AC.Izi zimapangitsa kuti DC ikhale yogwira ntchito pamayendedwe akutali komanso kutumiza mphamvu.

9. Mtengo wa zipangizo: Zida za AC (mwachitsanzo, ma transformer, jenereta, etc.) ndizofala kwambiri komanso zokhwima, choncho mtengo wake ndi wotsika kwambiri.Zida za DC (mwachitsanzo,ma inverters, ma voltage regulators, etc.), komano, nthawi zambiri amakhala okwera mtengo.Komabe, ndi chitukuko chaukadaulo wa DC, mtengo wa zida za DC ukuchepa pang'onopang'ono.
