摘要

低压感应电动机的绕组绝缘可调速驱动系统与voltage-fed大大强调了逆变器电压分布不均和过度的电压应力(dv / dt),导致过早绝缘击穿。本文介绍了逆变用5马力380v感应电动机绝缘特性的试验结果。8种不同类型的绝缘技术分别应用于40个感应电动机。绝缘特性在局部放电、电容、电流和损耗因数测试中进行了比较。并进行了高压脉冲绝缘击穿试验，得到了相应的击穿电压。

Accessing the insulation characteristics for stator windings of low-voltage induction motors for adjustable-speed drive applications

The winding insulation of low-voltage induction motors in adjustable-speed drive systems with voltage-fed inverters are substantially stressed by the uneven voltage distribution and excessive voltage stress (dv/dt), which result in the premature insulation breakdown. This paper describes test results of the insulation characteristics of a 5 HP, 380 V induction motors for inverter applications. Eight different types of insulation techniques are applied to 40 induction motors respectively. Insulation characteristics are compared with respect to partial discharge, capacitance, current, and dissipation factor tests. Also, the insulation breakdown tests by high voltage pulses are performed and the corresponding breakdown voltages are obtained.
