接地网腐蚀的诊断研究

根据电路原理和故障诊断原理，提出一种新的接地网腐蚀诊断方法。该方法将接地网看成纯电阻网络，利用实际接地网的拓扑结构和接地引线间电阻的测量数据，应用特勒根定理建立接地网的腐蚀诊断方程，通过求解诊断方程得到接地网支路导体的变化值，进而判断接地网的腐蚀程度。仿真计算、模拟实验和现场试验都表明，该方法可快速确定腐蚀支路。

Grounding Grid Corrosion Diagnosis

Based on circuit theory and principles of fault diagnosis,a new method of grounding grid corrosion diagnosis is proposed.This method will be as pure resistance of grounding grid network,the actual grounding grids and grounding of the topological structure of inter-wire resistance measurements,the application of Tellegen's theorem to establish grounding grid corrosion diagnosis equation,by solving the equation has been diagnosed slip grounding grid conductor changes in value,and then the extent of corrosion ...
