摘要:
由于电气化铁路、以接地为回路的输电系统等的客观存在,不可避免地会产生杂散电流,并使埋地管道因杂散电流而产生腐蚀。杂散电流腐蚀具有强度高、危害大,范围广、随机性强等特点,介绍了对直流杂散电流腐蚀的控制,提出了最大限度地减少干扰泄漏电流、符合安全距离、增加回路电阻、排流保护和其他保护等措施;并对强电线路、输油管道、油库等交流杂散电流腐蚀的防护方面提出了数种可采取的保护措施。
Abstract:
The occurrence of stray current is unavoidable due to the existence of the power transmission system of electric railway and grounded circuit,and makes buried corrosion occur on the buried pipeline.Stray current have many characteristics such as high intensity,heavy harm, wide extent and occurrence in random.The control of DC stray current corrosion is described and a number of prevention measures are proposed such as minimizing interference leakage current to the utmost,keeping safety distance,increasing circuit resistance,drainage protection and so on.Also several protective measures are raised to prevent from AC stray current corrosion under the intensive power line and on the oil pipeline and oil tank farm.
