摘要
为提升变电站电磁环境信息采集的工作效率,提高数据测量精度,研究制作一台变电站电磁环境智能移动监测装置。所设计的工频电场探头可实现3个方向工频电场同步测量;带有复位电路的工频磁场采集电路可消除磁阻传感器处于过强磁场干扰时的异常问题;外置温湿度模块可保证测量准确度,采用憎水性复合材料支架,在湿度小于70%条件下测量误差在5%以内。第三方测试结果表明,电磁场测量结果误差在5%以内,采用此装置在实际110 kV变电站进行电磁环境实测,可准确按规定路径自主行走并进行测量。建立三维模型,进行空间电磁场分布的仿真模拟,所得实测数据与仿真数据有相同的变化趋势,进一步验证装置测量的准确性。
In order to improve the efficiency of substation electromagnetic environment information collection and the accuracy of data measurement,an intelligent mobile monitoring device is designed and manufactured in this paper.Selfdesigned power frequency electric field probe can realize synchronous measurement of power frequency electric field in three directions.The power frequency magnetic field acquisition circuit with reset circuit can eliminate the abnormal problem caused by the interference of strong magnetic field to the magneto-resistive sensor.External temperature and humidity module are installed to ensure the accuracy of measurement.When the humidity is less than 70%,the measurement error is within 5%.The third-party test results show that the error of electromagnetic field measurement results is within 5%.The electromagnetic environment measuring results in actual 110 kV substation indicate that,this device can walk and measure accurately following the specified path.A three-dimensional model is established to simulate the spatial electromagnetic field distribution.The measured data and simulation data achieve the same change trend,which further verifies the measuring accuracy of the device.
