低频干扰电流探头中磁芯材料的选择对其检测性能的影响

The Influence of selection of Magnetic Material on Its Experimental Performance in Low Frequency Interference Current Probe

本文通过分别对采用铁氧体和铁基非晶合金为磁芯材料的低频干扰电流探头的测试性能的比较分析 ,讨论了由于铁基非晶合金自身良好的磁性能 ,使得电流探头在测试低频干扰电流时的测试性能大大提高 ,从而对于解决目前国内所设计制作的干扰电流探头在测试低频干扰电流时探头灵敏度低。

This paper compares and analyzes the experimental performance of low frequency interference current probe made from ferrite and from amorphous Fe-M-B alloy, discusses the great improvement of performance of current probe in the test of low frequency interference current due to amorphous Fe-M-B alloy's good magnetic performance.The analysis provides the experimental proof to the resolution of the problem of poor precision and low sensitivity in the test of low frequency interference current probe designed and manufactured in our country at present.
