在钢结构物的阴极保护中,保护电位是最重要的必需经常控制的参数。保护电位测量一般有两个目的:即观察被保护系统各部位电位分布是否均匀,以及是否经常处于最佳保护电位范围之内;并根据检测结果,及时分析原因,查找影响因素,调整控制,使之稳定在保护范围。电位测量方法是将被保护体接在电压表(内阻要求4×15.5欧姆/伏以上)的(-)端上,把基准电极接在(+)端
In cathodic protection of steel structures, the protective potential is the most important parameter that must be constantly controlled. Protection potential measurement generally has two purposes: to observe the protection system potential distribution of various parts of the uniform, and are often in the best range of protection potential; and based on test results, timely analysis of the causes, find the influencing factors, adjust the control so that Stable in the scope of protection. Potential measurement method is to be protected body connected to the voltmeter (internal resistance requirements 4 × 15.5 ohm / volt) above the (-) terminal, the reference electrode connected to the (+) terminal
