针对海南省17个地区,33所变电站的电力设施和基础设施的常见腐蚀形式和重点腐蚀部位进行调查,对变电站腐蚀程度进行分类。对海南省各地区的大气腐蚀性进行评价,其中达到C4级的地区为5个,并且沿海地区的腐蚀速率普遍高于内部地区。高润湿时间和高Cl-是海南省大气腐蚀的主要诱因。缝隙腐蚀和电偶腐蚀则是该地区电力设施最常见的腐蚀形式。 Aiming at the common corrosion forms and key corrosion sites of power facilities and infrastructure in 17 substations and 33 substations in Hainan Province, the corrosion degree of substations is classified. Atmospheric corrosivity was evaluated in all regions of Hainan Province, of which 5 were reached at C4 level, and the corrosion rates in the coastal areas were generally higher than those in the interior regions. High wetting time and high Cl- is the main cause of atmospheric corrosion in Hainan Province. Crevice and galvanic corrosion are the most common forms of corrosion in electrical installations in the area.
