摘　　要：采用溶液等电位原理，设计制作了能自动彻底消除杂散电流腐蚀，实现杂散电流在线监测的模拟实验装置。实验室模拟实验和氯碱厂现场试验结果均证实，用溶液等电位法消除杂散电流腐蚀是完全彻底的，监测杂散电流是准确可靠的。A simulative test plant was made to automatically eliminate stray current corrosion and realize on line monitor of stray current by using the solution isopotential.The results of the simulative test in lab and the test in situ in a salt plant show that the solution isopotential method can eliminate stray current corrosion exhaustively and monitor stray current corrosion accurately and reliably.
