摘要

逆变器浪涌是一种高压现象，它是由逆变器和负载(如电缆和电机)的阻抗不匹配引起的重叠返回波产生的。随着工业电机等电气仪表控制系统的发展，变频器已成为可能。随着功率半导体技术的发展，电流变化率的增加导致浪涌电压的升高，从而增加了故障事件的数量。局部放电(PD)测量评估技术具有重要意义，因为逆变器浪涌导致击穿的机理是局部放电产生的原因之一。本研究开发了一种重复脉冲电压发生器，用于检测逆变器浪涌中的局部放电。本文报道了用重复冲击电压发生器确定逆变电机绝缘质量的结果。

Evaluation of novel impulse voltage generator for detecting partial discharge

The Inverter surge is a high-voltage phenomenon that is generated by the overlap returning wave by impedance mismatching to an inverter and load like cables and motors. The inverter has been available by advancement of control system of electrical instrument, such as the industrial motor. The increase of current changing rate with the advance of power semiconductor causes the surge voltage to rise, increasing the number of failure events. The evaluation technology by partial discharge (PD) measurement is important because the mechanism leading to breakdown by the inverter surge is a cause of PD. In this study, a repetitive impulse voltage generator has been developed which is used in detecting PD in the inverter surge. We report the result that repetitive impulse voltage was applied to confirm the insulation dignity of inverter-fed motor insulation using the repetitive impulse voltage generator.
