Cathodic Protection Potential Remote Measure System for Buried Natural Gas Piping and Its Application

阐述了在上海天然气高压管道上进行电位遥测的活动,介绍了一种基于微功耗技术设计的数据远程遥控和传输系统的结构组成、配置和功能。通过遥测系统对杂散电流干扰下的管地电位测试分析及采取的排流措施。实践表明:该系统对杂散电流的实时监测效果显著,适用于天然气管道杂散电流干扰下的管道电位测量。

The potential remote measurement for high pressure natural gas piping in Shanghai was described in this article.The system structure,configuration and function of remote control data transmit system,which is designed based on micro-consumption electronic technology,was introduced.By using this telemetry system,the piping ground potential disturbed by stray current is measured and analyzed.It has been shown from practice that using this system for real-time monitoring stray current is prominently effective,thus,it is applicable to stray current disturbed potential of natural gas piping.
