摘要
文中采用电流环、钳型电流表等电流测量设备,精确测量管道或者其他部位的电流大小及方向,结合开挖检查,查找出阀室内绝缘故障的位置。对某输油管道阀室的阴极保护绝缘故障进行检测,发现阀室内电伴热金属丝与管道存在搭接,导致阀室内管道阴极保护欠保护。
In this paper,current measuring equipment such as current loop and clamp ammeter was used to accurately meas-ure the current size and direction of pipeline or other parts.Combined with excavation inspection,the insulation fault location of valve chamber was found out.The failure of cathodic protection insulation in a valve chamber of an oil pipeline was detected,and it was found that the electric hot wire in the valve chamber overlapped with the pipeline,leading to the underprotection of cathod-ic protection of the pipeline in the valve chamber.
