Umahluko phakathi kwe-DC yokumelana nesixhobo sovavanyo lombane kunye ne-AC yokumelana nesixhobo sovavanyo lombane

1. Ukwahluka ngendalo

Isixhobo se-AC sokumelana novavanyo lombane: eyona ndlela isebenzayo nethe ngqo yokuchonga amandla okufakelwa kwezixhobo zombane.

I-DC imelana nesixhobo sovavanyo lombane: ukukhangela amandla ombane aphezulu ngokwentelekiso ukuba isixhobo simelana nawo phantsi kovavanyo lwamandla ombane aphezulu.

2. Ezahlukeneyo ezitshabalalisayo

I-DC imelana nesixhobo sovavanyo lombane: Kuba ukugqunyelelwa phantsi kombane we-DC ngokwesiseko akuvelisi ilahleko ye-dielectric, i-DC ukumelana ne-voltage inomonakalo omncinci kwi-insulation.Ukongeza, ekubeni i-DC ukumelana ne-voltage idinga kuphela ukubonelela ngokuvuza okuncinci okwangoku, izixhobo zovavanyo ezifunekayo zinomthamo omncinci kwaye kulula ukuwuthwala.

I-GDYD-M yochungechunge lwe-insulation ukumelana nesixhobo sovavanyo lombane

I-AC yokumelana nombane: I-AC yokumelana nombane iyingozi kakhulu kwi-insulation kune-DC yokumelana nombane.Ekubeni uvavanyo lwangoku lusebenza ngoku, izixhobo zokuvavanya umthamo omkhulu ziyafuneka.

Uvavanyo lokuthintela i-insulation

Uvavanyo lokuthintela ukugqunywa kwezixhobo zombane ngumlinganiselo obalulekileyo wokuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo.Ngokusebenzisa uvavanyo, umgangatho wokufakelwa kwezixhobo ziyakwazi ukulawulwa, iziphene ezifihliweyo ngaphakathi kwe-insulation zingafumaneka ngexesha, kwaye iziphene zinokupheliswa ngokugcinwa.Ukuba inzulu, kufuneka itshintshwe ukuze kuthintelwe ukugquma kwesixhobo ukuba kwenzeke ngexesha lokusebenza.ukuqhekeka, okukhokelela kwilahleko engenakulungiseka njengokumka kombane okanye umonakalo wesixhobo.

Iimvavanyo zokuthintela i-insulation zingahlulwa zibe ngamacandelo amabini:

Olunye luvavanyo olungonakalisiyo okanye uvavanyo lweempawu zokugquma, eziziimpawu ezahlukeneyo zeparameters ezilinganiswe kumbane ophantsi okanye ngezinye iindlela ezingayi konakalisa isigqubuthelo, ngakumbi kubandakanywa umlinganiselo wokunganyangeki, ukuvuza kwangoku, ilahleko yedielectric tangent njl.njl. ., ukuze ugwebe ukuba kukho isiphene ngaphakathi kwesigqubuthelo.Iimvavanyo zibonise ukuba olu hlobo lwendlela luyasebenza, kodwa alunakusetyenziselwa ukugweba ngokuthembekileyo amandla e-dielectric of insulation okwangoku.

Olunye luvavanyo olutshabalalisayo okanye ukuxhathisa isixhobo sovavanyo lombane.Umbane osetyenzisiweyo kuvavanyo uphezulu kunombane osebenzayo wesixhobo.I-voltage yokumelana ikakhulu ibandakanya i-DC ukumelana nombane, i-AC yokumelana nombane njalo njalo.Ukungalungi kokusebenzisa isixhobo sokuvavanya umbane kukuba kuya kubangela umonakalo othile kwi-insulation.
