Ziziphi iingxaki ezimele ziqwalaselwe ekulinganiseni umlinganiselo we-absorption ratio polarization index

Imiqathango yokulinganisa umlinganiselo wokufunxa

Umlinganiselo we-absorption kunye ne-polarization index ye-transformer kunye neklasi ye-voltage ye-10kv kunye nomthamo we-transformer yenethiwekhi yokusabalalisa ngaphantsi kwe-4000kvA ayinakulinganiswa.

Xa inqanaba lombane we-transformer liyi-220kv okanye ngaphezulu kwaye umthamo ungaphezulu kwe-120MVA, umvavanyi we-5000V wokumelana ne-insulation kufuneka usetyenziswe ukulinganisa umlinganiselo wokufunxa.Umlinganiselo wokufunxa akufanele ube ngaphantsi kwe-1.5 kwiqondo lokushisa.Xa ixabiso lokumelana ne-insulation lingaphezulu kwe-10000MΩ kwi-R60min, isalathisi se-polarization ayifuni.

Ezi ngxaki zilandelayo kufuneka ziqwalaselwe ekulinganiseni i-absorption ratio polarization index

(1) Umlinganiselo ngamnye kufuneka ukhethe umvavanyi wokumelana nomgangatho wombane ofanayo, abavelisi abahlukeneyo abanampembelelo;

(2) Ngexesha lokulinganisa, umgca wokukhupha umbane ophezulu kufuneka ukhethwe njengomgca okhethekileyo wokukhusela umbane ophezulu, kwaye umgca wokuphuma uL kunye no-N awunakutshintshwa, umgca wokuvavanya akufanele ube nenxeba kwaye umiswe ngokusemandleni;

(3) Ukuthintela umrhumo oshiyekileyo ekuchaphazeleni iziphumo zovavanyo, into evavanyiweyo kufuneka ikhutshwe ngokupheleleyo phambi kovavanyo;

(4) Ngaphambi kovavanyo, susa ucingo lokuvavanya, sula umxube wokuvavanya kwaye uqinisekise ukuba umhlaba unokwethenjelwa;

(5) Ukuthintela impembelelo yokuvuza komphezulu wangoku kangangoko kunokwenzeka kumswakama womoya luvavanyo oluncinane, xa kuyimfuneko ukudibanisa umsesane wekhaka;

Ezi zingasentla ziingxaki ekufuneka ziqwalaselwe xa kulinganiswa i-absorption ratio polarization index.Kuyimfuneko ukunikela ingqalelo ekukhethweni kombane kwisixhobo sombane.Kufuneka ihambelane neenkcukacha zovavanyo.
