用瞬态波形存贮器统一直流、交流、脉冲磁性的测量

To Unify DC,AC and Pulse Magnetic Measurement Methods by Means of the Instantaneous Wave Storage

对用瞬态波形存贮器统一直流、交流、脉冲磁性测量进行了试验、分析 给出测量一般原理 ,并测量了直流、脉冲退磁曲线 ,交流磁滞回线 将直流、交流测量和传统的方法进行比较 ,对脉冲测量进行定量计算 ,并讨论了误差及引起误差的原因 对测量中遇到的问题以及解决方法 ,作了说明 结果证明文中方法是可行的 ,但一些技术性细节问题还有待改进 。

The DC,AC and pulse magnetic measurements using the instantaneous wave storage(IWS) are discussed and summarized:the general principle of the measurement is presented,and the DC and pulse demagnetized curves and AC hysteresis loop are measured,in which DC and AC measurements are compared with the conventional method.The quantitative calculation has been made on the pulse measurement,and the errors and their causes are discussed.The problems encountered during measurement and the solutions are explained in detail.It is believed that this method is feasible,but some technological problems need to be settled.
