[3] 张平,向波,龚树鸣,等. 埋地钢质管道交流干扰防护技术标准: 短时间内连续发生,也很难确认冲击固态去耦合器的 故障电流和雷电电流都低于其额定值。因此,对于固 态去耦合器的使用寿命很难做出确切的规定,有必要 研究适用于现场的检测方法。 3 结论 管道接地是对交流感应干扰进行缓解的有效措 施,在使用正电性材料接地或者外界存在直流杂散电 流干扰时,可通过固态去耦合器阻断管道与接地间的 直流通路。在固态去耦合器产品的选型指标、产品检 验检测及现场安装等方面,亟需专业的技术规范指导: (1)在设备选型时应对固态去耦合器产品的直流 电流泄漏量严格要求,以避免交流干扰防护设施对管 道阴极保护产生影响;固态去耦合器的某些重要技术 指标,如交流阻抗,在设备选型中尚未获得足够重视;Fail-Safe 功能应作为固态去耦合器的强制指标要求。 (2)接地材料铜和锌用于交流干扰防护时的腐蚀 寿命问题,尚待继续研究;对于已经采用铜作为接地材 料的管道排流点,应加强对管道电位和固态去耦合器 性能的检测、跟踪。 (3)产品性能的第三方检验、安装后的性能检验, 尚待继续研究。 (4)用于绝缘装置的过电压防护时,存在安装导线 过长的问题。 目前国内管道业界在交流干扰防护方面的设计理 念较为粗放。在进行故障电流以及电磁感应交流干扰 防护时,排流点的数量及设计工程量远超过实际需求, 既造成了工程投资的巨大浪费,又给管道后续的防腐 层和阴极保护检测带来负面影响。 GB/T 50698-2011[S]. 北京:中国计划出版社,2011:3.
