摘要
介绍了阳极串深井阳极的设计、选材和安装,深井阳极主要用于地表空间狭小或土壤电阻率高的场合下的阴极保护系统。采用深井阳极的优点是,阳极与被保护结构有一定距离,使保护电流的分布更加均匀,同时减小了对其它埋地金属结构的腐蚀干扰。为了便于阳极的安装,保证工程质量,近年发展起来的混合金属氧化物阳极串得到了广泛应用。
The design, material selection and installation of anode-string deep well anode are introduced in the article. The deep well anode is mainly used in the cathodic protection system that is at a narrow surface or at the soil with a high resistivity. The advantages of deep well anode embody that there is a relevant distance between the anode and the protected structure, which makes the distribution of protective current evener, and meanwhile, the corrosion disturbance to other buried metal structures reduced.
