Umahluko phakathi kweentambo zeDC kunye neze-AC kwiintambo zamandla

Intambo ye-DC ineempawu ezilandelayo xa ithelekiswa nentambo ye-AC.
1. Inkqubo esetyenzisiweyo yahlukile. Intambo ye-DC isetyenziswa kwinkqubo yokudlulisa i-DC elungisiweyo, kwaye intambo ye-AC isetyenziswa rhoqo kwinkqubo yamandla e-frequency yamandla (yasekhaya ye-50 Hz).

2. Xa kuthelekiswa nentambo ye-AC, ukulahleka kwamandla ngexesha lokudluliselwa kwentambo ye-DC kuncinci.

Ukulahleka kwamandla kwentambo ye-DC ikakhulu kukulahlekelwa kukumelana kwe-DC komqhubi, kwaye ukulahleka kobushushu kuncinci (ubukhulu buxhomekeke kukuguquguquka kwamandla emva kokulungiswa).

Nangona ukumelana kwe-AC kwentambo ye-AC ene-voltage ephantsi kukhulu kancinci kunokumelana kwe-DC, intambo ye-voltage ephezulu iyabonakala, ikakhulu ngenxa yesiphumo sokusondela kunye nesiphumo sesikhumba, ukulahleka kokumelana nobushushu kubangela inxalenye enkulu, ikakhulu i-impedance eveliswa yi-capacitor kunye ne-inductor.

3. Ukusebenza kakuhle kothumelo kunye nokulahleka komgca ophantsi.

4. Kulula ukulungisa umbane kunye nokutshintsha indlela yokudlulisela umbane.

5. Nangona ixabiso lezixhobo zokuguqula liphezulu kunele-transformer, ixabiso lokusebenzisa umgca wentambo liphantsi kakhulu kunelekhebula le-AC.

Intambo ye-DC ineepali ezintle nezimbi, kwaye ulwakhiwo lulula; intambo ye-AC yinkqubo yezintambo ezine ezinezigaba ezintathu, okanye iintambo ezintlanu, iimfuno zokhuseleko lokufakelwa ubushushu ziphezulu, ulwakhiwo luyinkimbinkimbi, kwaye ixabiso lentambo lingaphezulu kokuphindwe kathathu kunentambo ye-DC.

6. Intambo ye-DC ikhuselekile ukuyisebenzisa:

1) Iimpawu ezisisiseko zothumelo lwe-DC, kunzima ukuvelisa umbane obangelwa yi-induced kunye nomsinga ovuzayo, kwaye akuyi kuphazamisana nentsimi yombane eveliswa zezinye iintambo.

2) Intambo yokubeka engundoqo omnye ayichaphazeli ukusebenza kokudluliselwa kwentambo ngenxa yokulahleka kwe-hysteresis kwebhulorho yesakhiwo sentsimbi.

3) Inamandla aphezulu okubamba kwaye ikhusela kakhulu kuneentambo zeDC zesakhiwo esifanayo.

4) Intsimi yombane ethe tye, etshintshanayo ye-voltage efanayo ifakwa kwi-insulation, kwaye intsimi yombane ye-DC ikhuselekile kakhulu kunentsimi yombane ye-AC.

7. Ukufakela nokugcina intambo yeDC kulula kwaye ixabiso liphantsi.
