基于方形骨架的宽频雷击电流传感器理论研究与实验
Theoretical and Experimental Research on Broadband Lightning Current Sensor Based on Square Frame
摘要
Abstract
According to the requirements of accurate detection of the standard lightning current waveform characteristics in the national standard, two Rogowski coils with different structure parameters were designed.On the basis of in-depth analysis and calculation of the principle of coil measurement, the simulation and experimental study was carried out with the dynamic characteristics of the measurement.It is concluded that the measured current frequency range reached 50 Hz-394 MHz and 743 Hz-394 MHz for square and circular skeleton of the Rogowski coil respectively;the sensitivities of the coil square and the circular skeleton were 117 mV/kA and 111.3 mV/kA respectively.The actual test results show that, the lightning current sensor with two kinds of coil frame could detect the lightning current with rapid change, and exhibited good sensitivity and linearity.At the same time, the parameters of the coil designed with different structure were compared and analyzed.It is found that the lightning current sensor based on square frame exhibited smaller measurement error and wider lightning current frequency band.关键词
