摘要
针对变电站接地网腐蚀现象,研制了基于PC/104的接地网检测系统,该系统能准确测量接地网腐蚀速率、腐蚀深度和接地电阻等参数,有效地为用户提供接地网的腐蚀状况。本文提出了阶跃电位对接地网的测量原理,给出了仪器的总体框图,分别从硬件和软件入手完成对系统的设计。通过现场试验结果表明,该仪器数据准确可信,经济实用,具有较高的推广价值。
A new method for the transformer substation＇s Grounding Grids Corrosion has been developed based on PC/104.This proposed system can measure the parameters of Corrosion, such as rate, depth, the value of earth resistance accurately in order to ensure the customs hand these information very well.The measurement principle which uses Potential step method is proposed, and then the main function block diagram of equipment is given.The system hardware and software aspects are introduced in detail.The results of field application prove that the data of instrument is accurate and feasible.It ＇s worth brighter prospect for the economical and practical characteristic.
