technical field [0001] The invention is a stray current interference corrosion simulation optimization device. General areas of corrosion protection and piping technology involving metallic materials. Background technique [0002] At present, some units and research institutions have carried out laboratory simulation experiments on stray current interference, but due to the limitation of the experimental site, it is very difficult to realize the indoor simulation of stray current interference in long-distance pipelines, so usually only a single Root tubules combined with some small test pieces to simulate interference cannot effectively reflect the actual interference situation of long-distance pipelines. Moreover, the results of simulation experiments are limited by space, and the electric fields of cathodic protection and stray current interference sources have a great influence on each other, making it difficult to conduct experiments accurately and efficiently.
