摘要
接地网缺陷诊断是我国电力部门一项重大的反事故措施。针对目前不开挖检测方法过度依赖接地网施工图纸、检测时需全站停电等问题,论文提出了一种基于电磁场理论,结合区域分割检测进行接地网缺陷诊断的方法。首先,构建了基于电磁场理论的通电矩形线圈空间磁场的数学模型,并讨论了区域分割的原则,设计了缺陷诊断方法的测试流程;最后,为验证所述方法的有效性,设计了缺陷诊断仪。实验结果表明,该方法能够准确地判断接地网的缺陷情况,使接地网缺陷诊断真正可控,如能推广必将带来巨大的经济效益。
Grounding grid defect diagnosis is one major anti-accident measure of power department in our country,in view of the present non excavation detection method relying too much on grounding grid construction drawings,the problem such as total station blackout during testing,this paper proposes a defect diagnosis method based on electromagnetic field theory,combined with regional segmentation detection grounding grid.First of all,electrified rectangular coil space mathematical model of the magnetic field is constructed based on the theory of electromagnetic field,and the principle of regional segmentation is discussed,also the testing process of defect diagnosis method is designed.Finally,to verify the effectiveness of the described method,defect diagnosis instrument is designed.The experimental results show that the method can accurately determine the defect of grounding grid,the diagnosis of grounding grid defect iscontrolled,such as promotion will bring huge economic benefits.
