Umahluko phakathi kweentambo ze-DC kunye ne-AC kwiintambo zamandla

Intambo yeDC inezi mpawu zilandelayo xa ithelekiswa nentambo ye-AC.
1. Inkqubo esetyenziswayo yahlukile. Intambo ye-DC isetyenziswa kwinkqubo yothumelo elungisiweyo ye-DC, kwaye intambo ye-AC isoloko isetyenziswa kwi-frequency yamandla (yasekhaya 50 Hz) inkqubo yamandla.

2. Xa kuthelekiswa nentambo ye-AC, ilahleko yamandla ngexesha lokuhanjiswa kwentambo ye-DC incinci.

Ilahleko yamandla yentambo ye-DC ubukhulu becala yilahleko yokuxhathisa kwe-DC ye-conductor, kwaye ilahleko yokugquma incinci (ubungakanani buxhomekeke ekuguquguqukeni kwangoku emva kokulungiswa).

Ngelixa uxhathiso lwe-AC lwentambo ye-AC ye-voltage ephantsi inkulu kancinci kunokumelana ne-DC, intambo ye-voltage ephezulu ibonakala, ngakumbi ngenxa yesiphumo sokusondela kunye nesiphumo solusu, ilahleko yokumelana nokufakwa kwe-insulation kubala umlinganiselo omkhulu, ngakumbi ukungasebenzi okwenziwa yi-capacitor kunye ne-inductor.

3. Ukuhanjiswa okuphezulu kunye nokulahleka komgca ophantsi.

4. Kukulungele ukulungelelanisa okwangoku kwaye utshintshe indlela yokuhambisa amandla.

5. Nangona ixabiso lezixhobo zokuguqula liphezulu kunelo loguquli, iindleko zokusebenzisa umgca wentambo ziphantsi kakhulu kune-AC cable.

Intambo ye-DC inezibonda ezilungileyo kwaye ezimbi, kwaye isakhiwo silula; intambo ye-AC yinqanaba lesithathu leentambo ezine, okanye i-five-wire system, iimfuno zokhuseleko lokugquma ziphezulu, ulwakhiwo lunzima, kwaye iindleko zentambo ziphindwe kathathu kunentambo yeDC.

6. Intambo yeDC ikhuselekile ukuyisebenzisa:

I-1) Iimpawu zendalo zokuhanjiswa kwe-DC, kunzima ukuvelisa i-current induced current kunye ne-leakge current, kwaye ayiyi kuphazamisa intsimi yombane eyenziwa ngezinye iintambo.

2) Intambo yokubeka i-single-core ayichaphazeli ukusebenza kokuhanjiswa kwentambo ngenxa yokulahleka kwe-hysteresis yebhuloho yesakhiwo sensimbi.

3) Inamandla okuthintela aphezulu kunye nokhuseleko olusike kakhulu kuneentambo ze-DC zesakhiwo esifanayo.

4) Umbane othe tye, otshintshayo wombane wombane ofanayo usetyenziswa kwi-insulation, kwaye intsimi yombane ye-DC ikhuselekile kakhulu kunentsimi yombane ye-AC.

7. Ufakelo kunye nokugcinwa kwentambo ye-DC ilula kwaye ixabiso liphantsi.
