Abstract
The electromagnetic parameters of the dry-type air-core reactor are calculated by the finite element method in this paper, which contain serf inductance, mutual inductance, and eddy-current loss. The overall changing patterns of the dry-type air-core reactor's inductance are analyzed under different frequency source with inter-turn insulation defects. An effective method of impulse-voltage test to detect the inter-turn insulation defects within reactor is proposed based on the experimental results. Moreover, the testing method is actually implemented on a set of device to detect the reactor's insulation defects, which is also extensively discussed in the paper. Under conditions of good quality and short-circuit of inter-turn insulation in the reactor, the waveforms of its voltage and current are compared to examine the proposed method. The final result validates the effectiveness of the impulse-voltage test technique.关键词
