1. Iinkqubo ezahlukeneyo zokusetyenziswa:
Iintambo zeDCzisetyenziswa kwiinkqubo zothumelo lwamandla oluthe ngqo emva kokulungiswa, ngelixa iintambo ze-AC zisetyenziswa rhoqo kwiinkqubo zamandla ezisebenza kwi-industrial frequency (50Hz).
2. Ukulahleka Kwamandla Okuncinci Kwindlela Yokuhambisa:
Xa kuthelekiswa neentambo ze-AC, iintambo ze-DC zibonisa ukulahleka kwamandla okuncinci ngexesha lenkqubo yokudlulisela. Ukulahleka kwamandla kwiintambo ze-DC kubangelwa ikakhulu kukuxhathisa ngqo kwamandla ombane kwee-conductors, apho ukulahleka kobushushu kuncinci (kuxhomekeke kubukhulu bokuguquguquka kwamandla emva kokulungiswa). Kwelinye icala, ukuxhathisa kwe-AC kweentambo ze-AC ezine-voltage ephantsi kukhulu kancinci kunokumelana kwe-DC, kwaye kwiintambo ze-voltage ephezulu, ukulahleka kubalulekile ngenxa yempembelelo yokusondela kunye nempembelelo yesikhumba, apho ukulahleka kokuxhathisa kobushushu kudlala indima enkulu, ikakhulu okubangelwa yi-impedance evela kwi-capacitance kunye ne-inductance.
3. Ukusebenza kakuhle koThumelo kunye nokulahlekelwa yiMigca esezantsi:
Iintambo zeDC zibonelela ngokusebenza kakuhle kothumelo kunye nokulahleka okuncinci kwemigca.
4. Ilungele ukulungelelanisa iNdlela yoThumelo lwaMandla olutshintshayo kunye nolutshintshayo.
5. Nangona ixabiso eliphezulu lezixhobo zokuguqula xa lithelekiswa neetransformer, ixabiso lilonke lokusebenzisa iintambo zeDC liphantsi kakhulu kuneentambo zeAC. Iintambo zeDC zi-bipolar, zinesakhiwo esilula, ngelixa iintambo zeAC ziyinkqubo ye-four-wire okanye ye-five-wire enezigaba ezintathu ezineemfuno eziphezulu zokhuseleko lokufakelwa kunye nesakhiwo esintsonkothileyo. Ixabiso leentambo zeAC lingaphezulu kwesithathu kuneentambo zeDC.
6. Ukhuseleko Oluphezulu Ekusetyenzisweni Kweentambo zeDC:
- Iimpawu ezisisiseko zothumelo lwe-DC zenza kube nzima ukubangela umbane kunye nokuvuza kombane, kuthintelwe ukuphazamiseka kwe-electromagnetic nezinye iintambo ezibekwe kunye.
- Iintambo ezifakwe ngomsonto omnye azifumani lahleko ye-magnetic hysteresis ngenxa yeetreyi zentambo ezakhiweyo zentsimbi, nto leyo egcina ukusebenza kothumelo lweentambo.
- Iintambo ze-DC zinamandla aphezulu okukhusela i-short-circuit kunye ne-overcurrent.
- Xa kusetyenziswa amandla ombane afanayo ombane kwi-insulation, amandla ombane e-DC akhuselekile kakhulu kune-AC.
7. Ukufakela okulula, Ukulungiswa okulula, kunye neendleko eziphantsi zeentambo zeDC.
Ukuvala ubushushuIimfuneko zeVolthi kunye neKhona ye-AC kunye ne-DC efanayo:
Xa kusetyenziswa i-voltage efanayo kwi-insulation, intsimi yombane kwiintambo ze-DC incinci kakhulu kuneentambo ze-AC. Ngenxa yomahluko omkhulu wolwakhiwo phakathi kwala macandelo mabini, intsimi yombane ephezulu ngexesha lokunika amandla iintambo ze-AC ixinene kufutshane nomqhubi, ngelixa kwiintambo ze-DC, igxile kakhulu ngaphakathi komaleko we-insulation. Ngenxa yoko, iintambo ze-DC zikhuselekile (amaxesha angama-2.4) xa kusetyenziswa i-voltage efanayo kwi-insulation.
