【摘要】：在实验室进行埋地管道阴极保护模拟实验时,鉴于多种影响因素的考虑,需要同时进行多组实验,而阴极保护系统中的传统电源价格昂贵,数量有限,特别是对现场所埋试片进行阴极保护时,传统电源的使用极不方便。基于直流电源的埋地管道阴极保护替代方案,通过实验验证了以干电池作为强制电流阴极保护电源的阴极保护系统的有效性,利用失重法对替代方案中涉及的实验组与空白组的试件进行对比分析,结果表明:使用两节1.5 V干电池作为强制电流阴极保护电源的阴极保护系统,对于试件的保护至少在30天内是有效的。
[Abstract]:When the simulation experiment of cathodic protection of buried pipeline is carried out in the laboratory, in view of the consideration of many influencing factors, multiple groups of experiments need to be carried out at the same time, and the traditional power supply in the cathodic protection system is expensive and limited, especially when cathodic protection is carried out for the buried test pieces in the field, the use of the traditional power supply is very inconvenient. Based on the alternative scheme of buried pipeline cathodic protection based on DC power supply, the effectiveness of cathodic protection system with dry battery as forced current cathodic protection power supply is verified by experiments. The experimental group and blank group involved in the alternative scheme are compared and analyzed by weight loss method. The results show that two 1.5V dry batteries are used as forced current cathodic protection power supply. The protection of the specimen is effective for at least 30 days.
