Muhupenyu hwedu hwezuva nezuva, tinofanira kushandisa magetsi zuva nezuva, uye hatizivi magetsi akananga nemagetsi anowirirana, semuenzaniso, magetsi anobuda mubhatiri ndiwo magetsi akananga, nepo magetsi emumba neemumaindasitiri ari magetsi anowirirana, saka musiyano uripi pakati pemhando mbiri idzi dzemagetsi?
"Direct current", inozivikanwawo se "constant current", constant current imhando ye direct current, ndiyo current size uye direction hazvichinje nekufamba kwenguva.
Kuchinjana kwemagetsi
Kuchinjana kwemagetsi (AC)imagetsi ane hukuru negwara zvinoshanduka nguva nenguva, uye anonzi alternating current kana kungochinjana mafambiro nekuti avhareji yehuwandu hwemagetsi enguva dzose mudenderedzwa rimwe izero.
Mafambiro akafanana kune mafungu akasiyana-siyana akananga. Kazhinji mafungu acho anoshanduka kuita sinusoidal. Kuchinjana kwemagetsi kunogona kufambisa magetsi zvinobudirira. Zvisinei, kune mamwe mafungu anoshandiswa chaizvo, akadai semafungu etriangular nemafungu esquare.
Kusiyanisa
1. Kutungamira: Mumagetsi akananga, mafambiro emagetsi anogara akafanana, achiyerera munzira imwe chete. Kusiyana neizvi, mafambiro emagetsi mumagetsi anochinja nguva nenguva, achichinjana pakati pemafambiro akanaka neasina kunaka.
2. Kuchinja kwevoltage: Voltage yeDC inoramba yakadaro uye haichinji nekufamba kwenguva. Voltage ye alternating current (AC), kune rumwe rutivi, inoshanduka nekufamba kwenguva, uye frequency yacho inowanzova 50 Hz kana 60 Hz.
3. Kureba kwekutumira: DC ine simba shoma panguva yekutumira uye inogona kutumirwa kure. Kunyange zvazvo simba reAC mukutumira kure richarasikirwa nesimba guru, saka rinofanira kugadziriswa uye kubhadharwa kuburikidza netransformer.
4. Rudzi rwemagetsi: Masimba anowanikwa muDC anosanganisira mabhatiri nemasero ezuva, nezvimwewo. Masimba aya anogadzira magetsi eDC. Kunyange hazvo simba reAC richiwanzogadzirwa nemagetsi uye richipihwa kuburikidza nematransformer netambo dzekutumira magetsi kuti zvishandiswe mudzimba nemumaindasitiri.
5. Nzvimbo dzekushandisa: DC inowanzoshandiswa mumidziyo yemagetsi, mota dzemagetsi,Nzvimbo dzekuchaja mota dzemagetsi, nezvimwewo. AC inoshandiswa zvakanyanya mumabasa epamba. Alternating current (AC) inoshandiswa zvakanyanya mumagetsi epamba, kugadzira maindasitiri, uye kutumira simba.
6. Simba remagetsi: Simba remagetsi reAC rinogona kusiyana mumasekonzi, nepo simba reDC richigara risingachinji. Izvi zvinoreva kuti nesimba rimwe chete, simba remagetsi reAC rinogona kunge rakakura kupfuura reDC.
7. Mhedzisiro uye kuchengetedzeka: Nekuda kwekusiyana kwenzira yemagetsi uye voltage yemagetsi anochinja-chinja, zvinogona kukonzera mwaranzi yemagetsi, inductive uye capacitive effects. Mhedzisiro iyi inogona kukanganisa mashandiro emidziyo uye hutano hwevanhu pasi pemamwe mamiriro ezvinhu. Kusiyana neizvi, simba reDC harina matambudziko aya uye nekudaro rinofarirwa kune mimwe michina inonzwisisika kana mashandisirwo chaiwo.
8. Kurasikirwa Kwemagetsi: Simba reDC rinorasikirwa nesimba zvishoma kana richifambiswa kure nekuti harikanganiswi nekusagadzikana uye kupinza kwesimba reAC. Izvi zvinoita kuti DC ishande zvakanaka mukufambisa magetsi kure uye kufambisa magetsi.
9. Mutengo wemidziyo: Midziyo yeAC (semuenzaniso, matransformer, majenareta, nezvimwewo) yakajairika uye yakakura, saka mutengo wayo wakaderera. Midziyo yeDC (semuenzaniso,ma inverter, vanodzora magetsi, nezvimwewo), kune rumwe rutivi, kazhinji zvinodhura. Zvisinei, nekuvandudzwa kwetekinoroji yeDC, mutengo wemidziyo yeDC uri kudzikira zvishoma nezvishoma.
