Umehluko phakathi kwezintambo ze-DC ne-AC kumakhebuli kagesi

Ikhebuli ye-DC inezici ezilandelayo uma iqhathaniswa nekhebula le-AC.
1. Uhlelo olusetshenziswayo luhlukile. Ikhebula le-DC lisetshenziswa ohlelweni lokudlulisa olulungisiwe lwe-DC, futhi ikhebula le-AC livame ukusetshenziswa kusistimu yamandla yamandla (yasekhaya engu-50 Hz).

2. Uma kuqhathaniswa nekhebula le-AC, ukulahleka kwamandla ngesikhathi sokudluliselwa kwentambo ye-DC kuncane.

Ukulahleka kwamandla ekhebula le-DC ngokuyinhloko ukulahlekelwa kokumelana kwe-DC kwe-conductor, futhi ukulahlekelwa kokufakwa kuncane (usayizi uncike ekuguquguqukeni kwamanje ngemva kokulungiswa).

Ngenkathi ukumelana kwe-AC kwentambo ye-AC ene-voltage ephansi kukukhulu kancane kunokumelana ne-DC, ikhebula le-high-voltage lisobala, ikakhulukazi ngenxa yomphumela oseduze nomphumela wesikhumba, ukulahlekelwa kokumelana nokufakwa kwe-insulation kubala ingxenye enkulu, ikakhulukazi i-impedance ekhiqizwa i-capacitor kanye ne-inductor.

3. Ukusebenza kahle kokudlulisa kanye nokulahleka komugqa ophansi.

4. Kulula ukulungisa okwamanje futhi ushintshe isiqondiso sokudlulisa amandla.

5. Nakuba intengo yemishini yokuguqula iphakeme kuneye-transformer, izindleko zokusebenzisa umugqa wekhebula ziphansi kakhulu kunekhebula le-AC.

Ikhebula le-DC liyizigxobo ezinhle nezingezinhle, futhi isakhiwo silula; ikhebula le-AC liwuhlelo olunezigaba ezintathu ezinezintambo ezine, noma izintambo ezinhlanu, izidingo zokuphepha zokuvikela ziphakeme, isakhiwo siyinkimbinkimbi, futhi izindleko zekhebula zingaphezu kokuphindwe kathathu kunentambo ye-DC.

6. Ikhebula le-DC liphephile ukusebenzisa:

I-1) Izici ezingokwemvelo zokudluliselwa kwe-DC, kunzima ukukhiqiza i-current induced kanye nokuvuza kwamanje, futhi ngeke kuphazamise insimu kagesi ekhiqizwa ezinye izintambo.

2) Ikhebula lokubeka eliwumgogodla owodwa akuthinti ukusebenza kokudluliselwa kwekhebula ngenxa yokulahlekelwa kwe-hysteresis yebhuloho lesakhiwo sensimbi.

3) Inamandla okunqamula aphezulu kanye nokuvikela ukusika ngokweqile kunezintambo ze-DC zesakhiwo esifanayo.

4) Inkambu kagesi eqondile, eshintshanayo ye-voltage efanayo isetshenziswa ku-insulation, futhi inkambu kagesi ye-DC iphephe kakhulu kunenkambu kagesi ye-AC.

7. Ukufakwa nokugcinwa kwentambo ye-DC kulula futhi izindleko ziphansi.
