摘要
提出一种基于巨磁阻传感器的智能高压开关柜大电流测量方法。在论述巨磁阻效应及其测量机理的基础上,给出一套大电流测量和预警系统设计方案,说明了该系统的硬件和软件设计过程。通过实验的方法验证了巨磁阻传感器测量系统的稳定性和准确性。
A large current measurement method for intelligent high-voltage switchgear based on GMR magnetic sensor was proposed. On the basis of discussing the GRM effect and its measuring mechanism,the designing scheme for super-current measurement and early warning system was presented,including design process of the hardware and software of the system in detail. The experimental results verify both stability and accuracy of the GMR magnetic sensor measurement system.
