消磁工作线圈电流对纵向补偿的干扰研究

从现行消磁工作线圈电流对纵向补偿效果产生较大干扰的事实出发，研究其干扰程度。计算得到相关消磁线圈电感，利用法拉第电磁感应定律具体计算了在工作线圈电流首脉冲换向过程中纵向补偿线圈感应电流的大小。进而提出降低干扰的改进方案，通过科学计算及仿真分析检验了方案效果。研究结果表明改进方案可行。

Analysis of the Disturbance of Working Coil Current Cause to Compensating Coil in Synthetical Degaussing

From the fact that the actual degaussing current brings terrible influence on the lengthways compensation coil and deteriorate the erasure performance,this paper studied the degree of the influence.Through two methods,the paper obtain self-inductance and mutual-inducatance of degaussing coils.Then according to Faraday’s law of electromagnetic induction,the impact is quantified.On the base of that,the paper proposed a project to alleviate the impact.Calculation and emulational experiment testified the effectiveness of the project.
