【摘要】：根据相关标准规定,钢制埋地管道阴极保护效果评价应采用断电电位指标,现场测试通常使用同步中断法,但其并不适用于无法同步中断管中阴极保护电流、以及受杂散电流干扰的管段。阴极保护电位检查片可以解决这一难题,通过模拟管道防腐层漏点,利用检查片的瞬间断开电位实现近似管道断电电位的测量。本文详细介绍了管道阴极保护电位检查片的适用范围、设计、安装、测试及分析等内容,通过具体实施案例明确了数据记录的规范性,并验证了测试方法的可行性,为该方法的推广应用奠定实践基础。
[Abstract]:According to the relevant standard, the evaluation of cathodic protection effect of steel buried pipeline should be based on the electric potential index, and the synchronous interruption method is usually used in the field test, but it is not suitable for the cathodic protection current in the unsynchronized interrupting tube. And the section of the tube which is disturbed by stray current. The cathodic protection potential detector can solve this problem. By simulating the leakage point of the anticorrosion layer of the pipeline, the instantaneous disconnection potential of the detector can be used to realize the measurement of the approximate pipeline power failure potential. This paper introduces in detail the applicable range, design, installation, test and analysis of the pipeline cathodic protection potential inspection sheet, and clarifies the standardization of the data record through the concrete implementation case, and verifies the feasibility of the test method. It lays a practical foundation for the popularization and application of this method.
