Mu moyo wathu watsiku ndi tsiku, timafunika kugwiritsa ntchito magetsi tsiku lililonse, ndipo sitikudziwa bwino za magetsi olunjika ndi magetsi osinthasintha, mwachitsanzo, mphamvu ya batri ndi mphamvu yolunjika, pomwe magetsi apakhomo ndi a mafakitale ndi magetsi osinthasintha, ndiye kusiyana kotani pakati pa mitundu iwiriyi ya magetsi?
Mphamvu yamagetsi mwachindunji
"Direct current", yomwe imadziwikanso kuti "constant current", constant current ndi mtundu wa direct current, ndi kukula ndi njira ya current sizisintha pakapita nthawi.
Mphamvu yosinthira
Mphamvu yosinthira (AC)ndi mphamvu yamagetsi yomwe kukula kwake ndi momwe imayendera zimasinthasintha nthawi ndi nthawi, ndipo imatchedwa mphamvu yamagetsi yosinthasintha kapena mphamvu yamagetsi yosinthasintha chifukwa mtengo wapakati wa mphamvu yamagetsi yamagetsi munthawi imodzi ndi zero.
Njira yake ndi yofanana pa mafunde osiyanasiyana olunjika. Nthawi zambiri mawonekedwe a mafunde ndi sinusoidal. Mphamvu yosinthira imatha kutumiza magetsi bwino. Komabe, pali mafunde ena omwe amagwiritsidwa ntchito, monga mafunde amakona atatu ndi mafunde a sikweya.
Kusiyana
1. Malangizo: Mu mphamvu yolunjika, njira ya mphamvu nthawi zonse imakhala yofanana, ikuyenda mbali imodzi. Mosiyana ndi zimenezi, njira ya mphamvu yosinthasintha mphamvu imasintha nthawi ndi nthawi, kusinthana pakati pa njira zabwino ndi zoipa.
2. Kusintha kwa ma voltage: Voltage ya DC imakhalabe yokhazikika ndipo siisintha pakapita nthawi. Voltage ya alternating current (AC), kumbali ina, imakhala sinusoidal pakapita nthawi, ndipo nthawi zambiri imakhala 50 Hz kapena 60 Hz.
3. Mtunda wotumizira: Mphamvu ya DC imachepa pang'ono panthawi yotumizira ndipo imatha kutumizidwa patali. Ngakhale mphamvu ya AC mu transmission yakutali imatayika kwambiri, choncho iyenera kusinthidwa ndikulipidwa kudzera mu transformer.
4. Mtundu wa magetsi: Magwero amphamvu omwe amagwiritsidwa ntchito pa DC ndi mabatire ndi ma solar cell, ndi zina zotero. Magwero amphamvu amenewa amapanga mphamvu ya DC. Ngakhale kuti mphamvu ya AC nthawi zambiri imapangidwa ndi mafakitale amagetsi ndipo imaperekedwa kudzera mu ma transformer ndi ma transmission lines kuti agwiritsidwe ntchito m'nyumba ndi m'mafakitale.
5. Madera ogwiritsira ntchito: DC imagwiritsidwa ntchito kwambiri pazida zamagetsi, magalimoto amagetsi,Malo Ochapira Magalimoto a Moto (EV), ndi zina zotero. AC imagwiritsidwa ntchito kwambiri m'nyumba. Mphamvu yosinthira magetsi (AC) imagwiritsidwa ntchito kwambiri pamagetsi apakhomo, kupanga mafakitale, ndi kutumiza mphamvu.
6. Mphamvu yamagetsi: Mphamvu yamagetsi ya AC imatha kusiyanasiyana malinga ndi momwe imagwirira ntchito, pomwe ya DC nthawi zambiri imakhala yosasintha. Izi zikutanthauza kuti mphamvu yamagetsi ya AC ikhoza kukhala yayikulu kuposa ya DC.
7. Zotsatira ndi chitetezo: Chifukwa cha kusiyana kwa kayendetsedwe ka mphamvu ndi mphamvu ya magetsi a alternating current, izi zingayambitse kuwala kwa magetsi, mphamvu yopangira mphamvu ndi mphamvu. Zotsatirazi zitha kukhudza magwiridwe antchito a zida ndi thanzi la anthu nthawi zina. Mosiyana ndi zimenezi, mphamvu ya DC ilibe mavuto amenewa ndipo chifukwa chake imakondedwa pa zida zina zobisika kapena ntchito zinazake.
8. Kutayika kwa Mphamvu Yotumizira: Mphamvu ya DC imakhala ndi mphamvu zochepa zotayika ikatumizidwa mtunda wautali chifukwa sizikhudzidwa ndi kukana ndi kulowerera kwa mphamvu ya AC. Izi zimapangitsa DC kukhala yogwira ntchito bwino pakutumiza ndi kutumiza mphamvu mtunda wautali.
9. Mtengo wa zida: Zipangizo za AC (monga ma transformer, ma jenereta, ndi zina zotero) ndizofala kwambiri komanso zachikulire, motero mtengo wake ndi wotsika. Zipangizo za DC (monga,ma inverter, owongolera magetsi, ndi zina zotero), kumbali ina, nthawi zambiri amakhala okwera mtengo kwambiri. Komabe, ndi chitukuko cha ukadaulo wa DC, mtengo wa zida za DC ukuchepa pang'onopang'ono.
