V. Kev txiav txim siab ntawm cov cuab yeej muaj peev xwm
Yog tias plaub lub reactors tsim, ib lub reactor yuav yog 1500kVA / 200kV / 7.5A / 53H, thiab tag nrho cov peev txheej ntawm cov cuab yeej yuav yog 6000kVA.
1. AC tiv taus qhov ntsuas hluav taws xob rau GIS, nrog rau qhov ntsuas zaus ntawm 30-300Hz, capacitance
Tsawg dua lossis sib npaug rau 0.03uF, ntsuas qhov ntsuas hluav taws xob tsawg dua lossis sib npaug rau 800kV, thiab lub sijhawm sim ntawm 1min.
Siv plaub lub reactors hauv series (coefficient 1.6), L=53*4*1.6=339.2H, ces
Test zaus: f{{0}}/2π√LC=1/(2×3.14×√339×0.03×10-6)=50Hz
Test tam sim no: I{{0}}πfCU Test=2π × 50 × 0.03 × 10-6 × 800 × 103=7.5A- 4 -
Cov cuab yeej muaj peev xwm tau teeb tsa ntawm 6000kVA / 800kV; Lub reactor muab faib ua plaub
ntu, thiab ib ntu ntawm reactor yog 1500kVA / 200kV / 7.5A / 53H.
Los ntawm kev siv ua ke, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom kuaj tau hais los saum toj no.
