| 摘 要： | 通过对电工钢交流磁性检测方法现行国家标准（爱泼斯坦方圈法和标准单片法）在应用中存在的问题进行了梳理和解析，认为主要问题包括次级电压波形失真时需修正比总损耗、约定的有效磁路长度并非实际有效磁路长度以及磁性测量系统校准方法缺失等，并提出了采用数字反馈控制技术控制次级电压波形无需修正比总损耗、取向硅钢单片法测量时采用475 mm有效磁路长度以及磁性测量系统综合校准方案等一些解决方案。

| Abstract: | This paper groomed and analyzed the problems of current national standards of measuring methods for alternating current magnetic properties of electrical steel（including Epstein frame and single sheet test）, such as, correcting specific core loss while waveform distorted, assumed effective magnetic path length is not the true one, and lack of calibration method of magnetic test system. And some solutions were also proposed like using digital feeback control technology to avoid correcting specific core loss, assuming effective magnetic path length as 475mm, and comprehensive calibration method for magnetic test system. |
