摘要
介绍了宁波航煤管道的杂散电流干扰的检测结果及防护措施。检测结果表明,该航煤管道的电位波动是由于地铁杂散电流引起的,且干扰强度较大。使用阳极地床进行排流后,管地电位波动普遍减少了80%以上,杂散电流干扰排除结果满足或超过国家标准的排流要求,管道安全隐患得到了整治。
This section introduces the detection and control of stray current interference for Ningbo aviation fuel pipeline. With the detection, it is affirmed that the fluctuation of pipe-to-earth potential was affected by metro s~＇ay current, and the magnitude of interference is severe.The current was discharged by galvanic anodes bed, the fluctuation of pipe-to-earth potential was reduced up to 80%. The results of interference resolution meet or surpass the GB standards, the pipehne safety was guaranteed.
