1. Izinhlelo ezihlukile zokusebenzisa:
Amakhebula we-DCzisetshenziswa ezinhlelweni eziqondile zokuhambisa zamanje ngemuva kokulungiswa kabusha, ngenkathi amakhebuli e-AC asetshenziswa kakhulu ezinhlelweni zamandla ezisebenza kumvamisa yezimboni (50hz).
2. Ukulahleka kwamandla okuphansi ekudlulisela:
Uma uqhathanisa nezintambo ze-AC, amakhabethe ama-DC abukwa ukulahleka kwamandla amancane ngesikhathi senqubo yokuhambisa. Ukulahleka kwamandla kumakhekhe we-DC ngokuyinhloko kubangelwa ukumelana okuqondile kwabaqhubi, ngokulahleka kokufakelwa okuncane (kuncike ekushintshashintsheni kwamanje ngemuva kokulungiswa kabusha). Ngakolunye uhlangothi, ukumelana kwe-AC kwamakhekhe aphansi we-ac kukhulu kakhulu kune-DC ukumelana, futhi amakhekhe aphezulu, lapho kuncipha khona amandla okumelana nomphumela wesikhumba, lapho kutholwa khona amandla okuvikelwa yi-capcacitance kanye ne-intanethi.
3. Ukusebenza kahle okuphezulu nokulahleka komugqa ophansi:
Amakhekhe we-DC anikela ngokudluliswa okuphezulu kokudlulisela okuphezulu nokulahleka komugqa omncane.
4. Kulula ukuguqula ukuqondiswa kwamanje nokushintsha kwamandla okuhambisa amandla.
5 Amakhekhe we-DC ane-bipolar, enesakhiwo esilula, ngenkathi amakhebuli e-AC anezigaba ezintathu ezinama-wire ezine noma amahlanu anezidingo eziphakeme zokuphepha ezifakwayo kanye nesakhiwo esiyinkimbinkimbi ngokwengeziwe. Izindleko zezintambo ze-AC zingaphezu kwamahlandla amathathu ka-DC.
6. Ukuphepha okuphezulu ekusetshenzisweni kwamakhekhe we-DC:
- Izici ezingokwemvelo zokuhanjiswa kwe-DC kwenza kube nzima ukunxenxa kwamanje nokuvuza kwamanje, ukugwema ukuphazanyiswa kwe-electromagnetic nezinye izintambo ezibekiwe.
- Izintambo ezihlangene ze-single-core azinazo ukulahleka kwamandla kazibuthe ngenxa yamathreyi wensimbi ekhebula amakhebula, ukulondolozela ukusebenza kokuhambisa ikhebula.
- Izintambo ze-DC zine-Short-Circuit Circ-Circuit kanye nokuvikelwa kokuvikela.
- Lapho amasimu afanayo kagesi asetshenziswa ekufakweni, insimu kagesi ye-DC iphephe kakhulu kunenkambu kagesi ye-AC.
7. Ukufakwa okulula, ukulungiswa okulula, kanye nezindleko eziphansi zamakhekhe ama-DC.
UkwahlukanisaIzidingo ze-voltage efanayo ne-DC kanye namanje:
Lapho kufakwa i-voltage efanayo ekufakweni, insimu kagesi kumakhekhe we-DC incane kakhulu kunezintambo ze-AC. Ngenxa yokwehluka okubalulekile kwesakhiwo phakathi kwezinkambu ezimbili, inkambu kagesi ephezulu ngesikhathi se-AC Cable Energlization igxile eduze komqhubi, ngenkathi kufinyelela amakheshana e-DC, ikakhulukazi kugxila ngaphakathi kwesendlalelo sokufakelwa. Ngenxa yalokhu, izintambo ze-DC ziphephile (izikhathi ezingama-2.4) lapho kufakwa i-voltage efanayo ekufakweni.
