实用接地网腐蚀缺陷诊断评估系统的研究

Research on Diagnostic Evaluation System for Corrosion Defect of Practical Earthing Network

介绍一种自主研发的实用接地网腐蚀缺陷诊断评估系统,其硬件采集分析系统实现了自动采集、粗大误差报警及8路测试信号半双工传输等功能;软件诊断与评估系统的核心为诊断评估算法,实现了地网图形输入、可测性分析、测试方案优化选择、撕裂分块诊断和地网参数评估等功能。

The paper introduces a corrosion defect evaluation system of self development for practical earthing network, and the hardware acquisition analysis system of the system realizes the functions, such as automatic acquisition, gross error alarming as well as half-duplex transmission with 8-path test signals. Diagnostic evaluation algorithm based the software diagnosis ＆ evaluation system of the system realizes some functions, which are graphic input for the earthing network, testability analysis, optimal selection of test scheme, tear ＆ block diagnosis and parameters evaluation of the earthing network
