Grey correlation analysis on related factors of temperature drift in magnetic modulated DCCT

  • 摘要: 为进一步改善磁调制DCCT(Direct Current Current Transducer)的温度特性,将磁调制DCCT化整为零,利用灰色相关理论确定了DCCT各部分温度系数对整机的影响程度;同时,还提出了一种磁调制DCCT温度系数综合评价方法。根据磁调制DCCT的工作原理,把DCCT分为PCB(Printed Circuit Board)、线圈和取样电阻三部分,并分别测出DCCT整机、PCB、线圈和取样电阻的温度系数;然后,利用灰色相关理论对7个被测DCCT的各部分温度系数进行关联计算,获得相应的关联系数,从而确定DCCT温度特性的主要因素。根据DCCT温度特性的主、次要因素并结合工程实际,设定了概念DCCT作为参考,利用灰色相关理论计算出7个被测DCCT与参考DCCT的温度系数的灰色关联加权值,完成了被测磁调制DCCT温度性能的综合评价。最后,指出了降低DCCT整机温度敏感性的研究方向。
