摘要
在电气化轨道交通沿线,有列车经过的时候,轨道电流必将在地埋管道上产生较大的杂散电流,从而使地埋管道产生电化学腐蚀,对管道产生极大的破坏。因此,为找出腐蚀点的具体位置,设计了本检测设备,包括中断器及管道电位检测仪。设备以高速微处理器为系统核心,应用GPS技术,通过同步通断测量技术准确测量管道电位,并选用液晶屏及薄膜按键进行了良好的人机交互设计。
Along the line of the electrification subway,when there coming the train,the electricity of the railway would produce desirable stray current on the pipes covered under the earth,which can cause electrochemical corrosion that may make great harm to the pipes.In order to precisely locate the corrosion pit,this detection equipment containing interrupter and pipe electric potential detector has been designed.We adopt high-speed microprocessor as the system core and measure the pipe electric potential with the application of GPS technology,as well as the excellent design of HMI with LCD and film touch.
