面向电流互感器饱和检测的磁敏传感器误差修正方法
Error Correction Method for Magnetic Sensor for Current Transformer Saturation Detection
摘要
Abstract
In the complex magnetic environment of current transformer,the measurement error of magnetic sensor increases due to the non-uniformity of magnetic field and the change of magnetic field intensity.An error correction method for saturation detection of mag-netic sensor is proposed.The saturation detection process of current transformers is simulated and the type of error caused by magnetic sensors during the detection process is determined.Theoretical calculations is used to calculate the magnetic field parameters such as magnetic flux and magnetic field strength under the saturation state of the current transformer.Through the statistical analysis of the re-al-time output value of the magnetic sensor and its comparison with the theoretical value,the solution result of the detection error value is determined.Three methods is determined self correction,ferromagnetic interference correction,and current compensation are used to achieve error correction of magnetic sensors.The test results show that the correction deviation of magnetic flux and magnetic field strength of the magnetic sensor is obviously reduced after the error correction of the design method,the hysteresis loop of the output of the saturation detection of the current transformer is consistent with the actual situation,and the error is reduced by about 0.87 Wb.关键词
