摘　　要：采用电化学方法测量镀锌钢和碳钢电极在不同的电位下电化学阻抗谱,可以确定其阴极保护参数和最佳保护电位。通过实际应用,进一步证明了采用电化学阻抗谱测试的方法来研究阴极保护的最佳保护电位,简单可行,对防止接地网的腐蚀、延长接地网的服务寿命、保证接地装置的安全运行意义重大。外加电流阴极保护法采用远程控制,有效地降低了后期的运行维护费用。It is able to determine cathodic protection parameters and optimum protection potential by measuring electrochemical impedance spectrum （EIS） of galvanized steel and carbon steel electrodes under various potentials using electrochemical methods. Practical application further proves that it is simple and feasible of studying optimum protection potential of cathodic protection using EIS. It has great significance in ground grid corrosion prevention, prolonging ground grid life, and ensuring ground devices safe operation. External current cathodic protection uses remote monitoring, which effectively reduces operation and maintenance costs.
