铁基超微晶软磁合金在暂态冲击电流测量中的应用

Application of Fe-based Super-microcrystalline soft Magnetic Alloy in Measurement of Transient Pulse Current

介绍一种新型材料——铁基超微晶软磁合金在暂态冲击电流测量中应用。因其具有高饱和磁感应强度、低矫顽力,低高频损耗、高起始磁导率和高频特性好等优点.我们用它作铁芯。利用磁感应原理来测量上升时间为几微秒和几百微秒、幅值在1kA以下的暂态冲击电流。

This paper introducs the application of a new mateial-----Fe - based supermicrocrystalline soft magnetic alloy in the measurement of transient pulse current. Because of the alloy has excellent properties such as high saturation magnetic induction, low coerice force, low high-frequency loss, high initial pemeability and good high frequency characterstic. we use the iron core rolled with the alloy ribbon, based on the magnetic inducing theory, to induce the trasient impulse current, of which rise times is from several microseconds to hundreds microseconds and peak value is up to 1kA.
