摘　　要：位于滨海滩涂的接地装置受海水电化学腐蚀、海洋微生物和海洋生物腐蚀的影响,引起接地体的受损甚至断裂,得不到有效保护的焊接点因腐蚀而受损,严重时引起接地体剥离,接地装置解裂。文章分析了金属接地体的腐蚀成因,并从接地体的选择、优化接地体布置方式、焊接点的防腐蚀和接地装置腐蚀防护等方面进行研究分析,得到提高滨海滩涂输电线路接地装置耐腐蚀性的方法。The grounding conductors in coastal mud fiat area may be damaged or break off from the earthing devices due to electrochemical corrosion of sea water, and marine microorganism and organism corrosions, and even worse damages may be expected for corrosion on the vices based on the corrosion protection due to the above corrosions to the unprotected welding joints. The paper analyzes the causes grounding conductor, and obtains corrosion-protection improvement methods for the earthing de- analyses on selection of grounding conductors, layout optimization of grounding conductor, and of welding joint and earthing device.
