摘要
针对传统电流互感器体积大、成本高及信息化程度低的问题,提出一种基于磁传感阵列的10kV开关柜电流测量方法.基于傅里叶级数理论,建立了磁传感阵列的数学模型和拓扑模型,设计了一套实验系统对模型进行检验,并根据实验结果对阵列拓扑进行了优化.同时对磁传感阵列测量法的误差进行分析,提出了进一步改进的方法.
According to disadvantages of large size, high cost and low informatization degree for traditional current transformer,a new measuring method based on the magnetic sensor array for the 10 kV switch board was proposed. The mathematical model and the topological model for the array were constructed based on Fourier series theory, and related experiments were designed to confirm the modeling method. According to the experimental results, array topology was optimized, measuring error of the method was analyzed,and then a modified method was proposed.
