Variable Frequency series resonance test System yog tsim los ua kom tau raws li cov qauv siab tshaj plaws, kom ntseeg tau tias nws ua tau zoo thiab ntseeg tau hauv txhua daim ntawv thov. Nrog rau ntau yam ntawm resonant zaus muaj, xws li transformer, cable, switchgear, CT PT, GIS, Circuit Court breakers.
8400kVA / 600kV Variable Frequency series resonance test System Tested daim ntawv thov thiab yuav tsum tau
1.For 400kV/2000mm2 cable 1km ACHV test, capacitance Tsawg dua los yog sib npaug rau 0.209uF, xeem zaus 20-300Hz, kuaj voltage tsis tshaj 420kV, xeem lub sij hawm 60min.
2, Rau 400kV thiab hauv qab substation khoom: CT, GIS, hloov, Circuit Court breaker, bushing, xeem voltage Tsawg dua los yog sib npaug rau 600kV, xeem lub sij hawm 1 ~ 15min;
Kev ua haujlwm
1.Ib puag ncig kub: -100C -{2}}C; 2.relative humidity: Tsawg dua los yog sib npaug rau 90% RH; 3.altitude: Tsawg dua lossis sib npaug li 1000m;
