摘要
以JN-QD长输天然气管道为例,根据其2010年-2014年期间管理处阴极保护系统出现故障的种类及频率,对阴极保护系统故障进行分类讨论。根据这7种故障对阴极保护系统的影响,将其分为:直接影响类故障,间接影响类故障和干扰类故障,并对这3类故障分别进行阐述。
Based on JN-QD natural gas pipeline as an example, according to the type and frequency of the period 2010-2014 Management Office of cathodic protection system failure, classifies and discusses on the cathodic protection system failure. According to the characteristics of all kinds of faults, the cathodic protection fault is divided into three categories: direct effects, indirect effects, interferential effects, respectively put forward different solutions to the three types of fault.
