摘要:
针对电机匝间短路故障诊断高频浪涌波形测试法存在过度灵敏且测试设备不便携的缺点,提出引入MCA技术,将电机看作包含电感和电阻的复杂等效电路,通过便携的ALL-TEST ⅣPro电机故障检测仪对电机施加高频正弦波,得到阻抗、倍频值和相位角3个核心参数,从而实现电机绕组匝间短路与鼠笼转子导条断裂等故障的快速诊断和定位。试验证明,该方法可提高电机故障诊断的准确率。
Abstract:
Aiming at the problem that high frequency surge waveform testing method for fault diagnosis of interturn short circuit of motor winding had the disadvantage of being too sensitive and not portable, a portable MCA technology was introduced, which regarded the motor as a complex equivalent circuit including inductance and resistance, applied a high frequency sine wave to motor with ALL-TEST IV Pro motor fault detector, and produced three key parameters: the impedance, the doubling frequency value and the phase angle, so as to realize the quick diagnosis and location of the fault such as interturn short circuit of motor winding and the broken guide bar of the squirrel cage rotor. The test results showed that this method could improve the accuracy of motor fault diagnosis.
