摘　　要：基于有限元方法并结合现场试验开展了35kV干式空心并联电抗器匝间短路保护特征量的研究,研究结果表明,35kV干式空心并联电抗器匝间短路时电抗器的电压幅值变化不大。Based on the finite element method, combined with field test, the protection characteristic quantity of turn-to-turn short circuit in 35kV dry-type air-core shunt,reactor are researched. The results indicated that the change of voltage amplitude is not obvious during the turn-to-turn short circuit in 35kV dry-type air-core shunt reactor.
