Umsebenzi kunye nendlela yokukhetha ye-AC / DC yokumelana novavanyo lombane

I-AC / DC yokumelana novavanyo lombane kukuveza isixhobo esivavanyiweyo kwindawo enzima kakhulu yombane.Ukuba imveliso inokugcina imeko eqhelekileyo kule ndawo yombane enobunzima, inokumiselwa ukuba inokugcina nokusebenza okuqhelekileyo kwindawo eqhelekileyo.Ngokubanzi, emva koyilo lwemveliso, ukuveliswa, ukuqinisekiswa komgangatho kunye nokugcinwa, uvavanyo loxinzelelo luyafuneka ukuze kuqinisekiswe ukuba imveliso ihlangabezana nemigangatho yokhuseleko kuzo zonke iinkalo.Iimveliso ezahlukeneyo zineenkcazo ezahlukeneyo zobugcisa.I-AC / DC yokumelana novavanyo lombane kukuvavanya iimveliso ezinombane ophezulu kunombane osebenzayo oqhelekileyo, ekufuneka uhlale ixesha elithile.

1. Ukukhethwa kwe-DC ukumelana nezixhobo zovavanyo lombane

I-DC yokumelana novavanyo lombane idinga amandla ombane aphezulu wovavanyo, onempembelelo ekhethekileyo ekufumaneni iziphene ezithile zasekhaya zokugquma.Inokuthi iqhutywe ngaxeshanye kunye novavanyo lwangoku lokuvuza.

Xa kuthelekiswa novavanyo lwe-AC lokumelana nombane, uvavanyo lombane lombane lwe-DC lunoncedo lwezixhobo zovavanyo olulula, umonakalo omncinci wokugquma kwaye kulula ukuzifumana iziphene zasekhaya.Xa kuthelekiswa novavanyo lokumelana nokumelana nombane we-AC, eyona nto ingeloncedo yokumelana novavanyo lombane we-DC kukuba ngenxa yolwabiwo lombane olwahlukileyo kwi-insulation ephantsi kwe-AC kunye ne-DC, uvavanyo lokumelana novavanyo lombane we-DC lusondele kwiimfuno zokwenene zovavanyo kunovavanyo lokumelana nombane we-AC. .

2. Ukukhethwa kwe-AC yokumelana nezixhobo zovavanyo lombane

Uvavanyo lokumelana nombane we-AC lungqongqo kakhulu ekugqumeni, olunokuthi lufumane ngokufanelekileyo iziphene eziyingozi ngakumbi.Yeyona ndlela ichanekileyo yokuchonga amandla okufakelwa kwezixhobo zombane, eyona nto ibaluleke kakhulu ukugweba ukuba izixhobo zombane zinokufakwa ekusebenzeni, kwaye ikwayindlela ebalulekileyo yokuqinisekisa umgangatho wokufakelwa kwezixhobo kunye nokuphepha iingozi zokugquma.

Ukumelana novavanyo lwe-voltage ye-AC ngamanye amaxesha kunokwenza ubuthathaka bokugquma ubushushu buphuhliswe ngakumbi, ke kuyafuneka ukuba kuvavanywe ukuxhathisa kwe-insulation, umlinganiselo wokufunxa, ukuvuza kwangoku, ilahleko ye-dielectric kunye nezinye izinto phambi kovavanyo.Ukuba iziphumo zovavanyo zifanelekile, uvavanyo lwe-AC lokumelana nombane lunokwenziwa.Ngaphandle koko, kufuneka kujongwane nayo ngexesha, kwaye uvavanyo lwe-AC lokumelana nombane kufuneka lwenziwe emva kokuba zonke izalathisi zifanelekile, ukuze kuthintelwe umonakalo ongeyomfuneko wokugquma.

I-AC / DC yokumelana novavanyo lombane luvavanyo olungqongqo kakhulu kwi-insulation kunye nokumelana nokusebenza kombane wento evavanyiweyo.Ngokusebenzisa i-AC / DC yokumelana novavanyo lwe-voltage, iziphene ezinokubakho kunye neengozi ezinokuthi zibekho zokhuseleko lwento evavanyiweyo inokufumaneka kwinkqubo yovavanyo.
