摘　　要：通过某变电站接地网腐蚀严重这一现状分析其腐蚀原因,从电化学的角度分期其腐蚀原理,并针对电化学腐蚀原理提出利用电化学原理采用阳极保护法的原则,并提出在各种土壤环境下选取不同的阳极材质进行保护,并提出一般采用较组成变电站接地网扁钢更为活泼的金属与接地网连接,形成无源电路模型,利用牺牲阳极的方法来保护阴极的接地网,最后从电化学的角度得到非常实用的变电站接地网防腐蚀方案。The article the author through the substation ground network this serious corrosion by analyzing the corrosion reasons, from the Angle of the electrochemical staging its corrosion principle, using the electrochem- ical principle are put forward based on electrochemical corrosion principle based on the principle of anode pro- tection law, and puts forward the selection of different anode material under various soil environment protec- tion, and put forward the general use of a substation grounding network flat more active metal and grounding network connection, form the passive circuit model, the method of using sacrificial anode to protect cathode grounding network, and finally from the point of view of electrochemical very practical substation ground net- work anticorrosion scheme.
