摘要

提出了一种基于电磁感应原理的自供电励磁涌流测量系统。信号线圈和功率采集线圈采用Rogowski线圈，嵌套在电流通道中。电源单元从涌流中提取能量。经过信号调理，可以得到瞬态浪涌电流的极性、峰值和发生时间。可以对当前信息进行断电存储，并通过ZigBee协议实现无线数据传输。实验证明，该系统可以利用浪涌电流自供电，实现10kA ~ 200kA范围内的线性测量。

A Self-powered Wireless Inrush Current Measurement System

A self-powered inrush current measurement system based on the electromagnetic induction principle is proposed. Signal coil and power harvesting coil adopt Rogowski coils, which are nested in the current channel. Power supply unit draw out energy from inrush current. After signal conditioning, polarity, peak value and occurrence time of transient surge current can be acquired. The current information can be power-down stored, and wireless data transmission is achieved through ZigBee protocol. Experiments prove that the system can be self-powered by inrush current and realize linear measurement within the range of 10kA to 200kA.
