摘要

本文在分析高频电流互感器(HFCT)工作原理的基础上，设计了一种用于电缆中间接头局部放电(PD)检测的高灵敏度小型HFCT，并对影响传感器灵敏度的因素进行了分析。仿真分析和实验结果表明，该传感器在通带内具有良好的线性度，在1MHz~5MHz频率范围内的增益可达到44dB (150mV/mA)以上，灵敏度高，并能耦合出较小的局部放电电流，具有较强的实际应用价值。

A high sensitivity high-frequency current sensor design

In this paper, based on the analysis of the working principle of high-frequency current transformer (HFCT), a high sensitivity small HFCT is designed for partial discharge (PD) detection of cable intermediate joints, and the factors affecting the sensitivity of the sensor are analyzed. The results of simulation analysis and experiments show that the sensor has good linearity in the passband, and the gain in the frequency range of 1MHz~5MHz can reach more than 44dB (150mV/mA), with high sensitivity, and can couple out the small partial discharge current, which has strong practical application value.
