摘　　要：利用爱泼斯坦方圈测试系统,首先针对变压器制造厂商常用国内外取向硅钢片磁性能和损耗曲线进行测量和对比分析。其次,对比分析了电工钢片退火前后磁性能数据和损耗数据,目的是研究退火对电工钢片磁性能的影响。然后,考察长期运行条件下硅钢片磁特性的变化情况。最后,针对标准外不同频率和温度影响下的电工钢片磁特性进行了测量。本次测量获得的取向硅钢片磁性能数据对取向硅钢片磁性能模拟技术及变压器铁心设计、制造等方面研究具有重要意义。Firstly,the magnetic properties and loss curve of the commonly used domestic and foreign oriented silicon steel are measured and compared.Secondly,the comparison and analysis of the magnetic performance and the loss data before and after the annealing are made to study the influence of annealing on the magnetic properties of the electrical steel sheet.Then,the changes in the magnetic properties of silicon steel on the long-term operating conditions are studied.Finally,the magnetic properties of the electrical steel sheets are measured under different frequencies and temperatures.The magnetic properties of oriented silicon steel obtained from this measurement are of great significance for the research on the magnetic properties of oriented silicon steel and the design and manufacture of transformer cores.
