- 摘要:
区域阴极保护系统是保障站内埋地管道、设备安全运行的重要措施。通过岳106井站增加区域阴极保护系统对站内埋地管道进行保护的实践,分析得出阳极地床形式的选择和位置的布置对于区域阴极保护系统的正常运行具有十分重要的意义。对于已建站场,如选择深井阳极地床则可大大减少现场施工工程量,同时也能发挥非常好的保护效果;区域阴极保护系统通电点的设置一定要考虑阴极保护电流的均匀分布情况,防止出现电流屏蔽现象,才能使站内所有埋地管道得到保护;区域阴极保护系统用设备可采用阴极保护成套橇装设备,橇装设备既能保证施工质量,减少现场施工工程量,同时也方便区域阴极保护系统今后的日常维护管理。
Regional cathodic protection system is an important measure to ensure the safe operation of buried pipelines and equipment in the station.By increasing regional cathodic protection system for protection of buried pipeline in AN YUE 106 well station, it is concluded that the form and position of the anode ground bed is of great significancefor the normal operation of the regional cathodic protection system,and for established station, the deep well anode ground bed can greatly reduce the workload at site, also can provide a very good protection effect.The setting of the drain point of the regional cathodic protection system must consider the uniform distribution of the cathodic protection current,and prevent the occurrence of current shielding,so as to protect all buried pipelines in the station.The prefabricated equipment of cathodic protection can be used for the regional cathodic protection system, which can not only ensure the construction quality and reduce the workload at site, but also facilitate the daily maintenance and management of the regional cathodic protection system in the future.
