V. Kev txiav txim siab ntawm cov cuab yeej muaj peev xwm Yog tias plaub lub reactors raug tsim, ib lub reactor yuav yog
1500kVA / 200kV / 7.5A / 53H, thiab tag nrho lub peev xwm 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, lub peev xwm tsawg dua lossis sib npaug rau 0.03uF, ntsuas qhov ntsuas hluav taws xob tsawg dua lossis sib npaug ntawm 800kV, thiab lub sijhawm sim ntawm 1min. Siv plaub lub reactors hauv series (coefficient 1.6), L=53*4*1.6=339.2H, ces
