沧州、衡水地区变电站接地网腐蚀情况分析

Corrosion Analysis on Earthing Network of Cangzhou and Hengshui Substation

通过对沧州、衡水地区部分变电站接地网开挖检查和土壤分析,初步掌握了沧州、衡水部分代表性变电站接地网腐蚀情况,以pH值、氯离子含量、矿化度(全盐含量)、土壤电阻率等因素来综合评价土壤腐蚀性,划分了沧州、衡水地区土壤腐蚀性等级,为沧州、衡水地区接地网选材和防腐措施选用提供了基础依据。

Through soil analysis and digging on earthing network of Cangzhou and Hengshui substation, the corrosion condition of Cangzhou and Hengshui substation is mastered. The soil causticity is evaluated from the aspects of pH value, Cl hydronium content, mineralization degree and soil resistance,the soil causticity level of Cangzhou and Hengshui region are measured off,to provide based foundation for material chosen and anti-corrosion measures chosen of earthing network of Cangzhou and Hengshui region.
