摘要

电机定子绕组温升限值和测试要求由行业标准、客户规范或绝缘系统中使用的材料确定。NEMA, IEC和CSA标准描述了如何根据某些标准测量定子绕组温升，例如电机的额定值或机架尺寸。本文详细介绍了这些标准的差异，以及所测试的电机温升如何根据所使用的标准而变化。研究了放置在定子槽内的嵌入式探测器测量的温升值，并将其与热稳定测试的结果进行了比较，热稳定测试的温度是通过电阻计算确定的。提供了大中型电机的试验数据。

Stator Winding Temperature Rise Testing for Medium and Large Polyphase Induction Motors Investigated

Motor stator winding temperature rise limits and test requirements are established by industry standards, customer specifications or the materials used in the insulation system. NEMA, IEC, and CSA standards describe how stator winding temperature rise is measured based on certain criteria, such as the rating or frame size of the motor. This paper details the differences in these standards and how the tested motor temperature rise varies depending on the standard being used. The value of temperature rise measured by embedded detectors placed in the stator slot is investigated and compared to the results from thermal stabilization tests where the temperature is determined from a rise by resistance calculation. Test data for Medium and Large motors is provided.
