Pages: 21-27
Year: Issue:  9
Journal: Transactions of China Electrotechnical Society

Abstract: 研究了Rogowski线圈电流传感器传感头的频率特性,在分析已有传感头信号处理方法的基础上,总结出利用终端电阻值来调整线圈的阻尼率,从而将传感头的频率响应分作三个特征区域,后继信号处理电路的设计针对各频段特性分别进行处理;文中给出了一种新型结构的自积分与外积分复合式罗氏线圈积分器的设计过程和参数选取方法,在保证传感器具有合适灵敏度的前提下,将传感器的工作频带拓宽到线圈的自然谐振频率.仿真与实验验证...
