摘要: Corona cage was an important research method to corona effect. As design cage, the distance form wall conductor, critical of AC charge, and length, these questions should be resolved. onset voltage, breakdown voltages were coefficients conductor characteristics, this significant for transmission line design. To a certain diameter small enough make at low voltage. Simultaneously, gap between lager enough, so as voltage 50% higher than The charge calculated, length selected. cross-section side width 1.8m × 1.8m., measurement 3m, both protection 0.5m respectively. in test, conductors placed center loss system adopted measure loss. LGJ-630/45, LGJ-400/35, LGJ-300/40 measured, excellent test effect obtained.
