摘要

为了了解设备表面和内部的工频电场

从而更好地研究设备运行的状态及优化改进设备

笔者介绍了一维球型电场传感器的测量原理

设计了一种基于C8051F410单片机的便携式工频电场测量装置

讨论了不同形状及规格电场探头对测量结果的影响并完成了电场探头的选型。在500 kV交流输电线下方和实验室简化同心圆球电极内使用该装置与国外标准仪器进行了对比测量

现场测试结果表明该装置测量数据与国外仪器相比具有较大的相关度

能准确地测量电力系统工频电场

具有很好的实用性。

Abstract

Measuring principle of one-dimensional spherical sensor for electric field is introduced.A portable power frequency electric field measurement device based on C8051F410 MCU is designed.The influences of different shapes and specifications of electric field probes on measurement result are analyzed

and a suitable electric field probe is hence selected.Measurements of the electric fields under a 500 kV AC power transmission line and inside a simplified concentric ball electrode in laboratory indicate that this device can accurately measure power frequency electric field of power system

and the measured data show high correlation with those from the foreign standard instrument.
