脉冲电流法在矿用防爆变压器局部放电监测中的应用

Application of Pulse Current Method in Partial Discharge Monitoring of Mine-used Flameproof Transformer

局部放电在线监测已成为监测变压器绝缘系统的一种有效手段。分析了局部放电对绝缘劣化的影响,以脉冲电流法为切入点,对矿用防爆变压器的局部放电监测进行了简要论述,并说明了其在煤矿应用中的意义。

Partial discharge monitoring has already become an effective means of monitoring transformer insulation system.Analysed the influences of local discharge to insulation deterioration,taking the pulse current law as a starting point,partial discharge of mine-used flameproof transformer were briefly discussed in this paper,and the significance of application in coal mine was also illustrated.
