大罐罐底阴极保护全寿命周期监测技术研究
Study on Life-Circle Monitoring Technology of Cathodic Protection on Tank Bottom
摘要
Abstract
For monitoring the effect of cathodic protection on the tank bottom, the long-term reference electrode( Cu/CuSO4 ) was laid in the sand seam of tank bottom foundation during the construction. Because the longest life of the long-term reference electrode( Cu/CuSO 4 ) is 10 a, and the design life of the cathodic protection of tank bottom is at least 30 a. If the reference electrode fails, it cannot be replaced and the protection potential cannot be detected. On the other hand, if the reference electrode fails, the transformer cannot receive the potential signal feedback from the reference electrode so that the transformer should not automatically adjust the output current. So the cathodic protection system cannot operate normally. Therefore, it is necessary to embed reference electrode channel in the tank bottom so that the reference electrode can measure the potential value in the tank bottom.关键词
