关于接地降阻材料的应用研究

Research on the Application of Grounding Resistance Reducer

重点分析和研究了降阻材料中降阻剂,电解地极的降阻机理;论述了降阻剂在实际接地工程中对接地体的腐蚀,降阻的稳定性,降阻效果,施工工艺以及降阻剂对环境的污染等问题;提出了在选择降阻剂时,应从降阻剂的电阻率,对钢接地体的腐蚀率,降阻剂的稳定性和长效性,对环境的污染以及降阻剂的价格等方面综合考虑;阐述了降阻措施应建立在对接地装置周围的地形、地势及土壤电阻率分布进行认真勘探、测量的基础上。

The resistance reduction mechanism of ground resistance reducing material and electrolytic electrode are studied. Corrosion of resistance reducer on grounding object in grounding engineering,it＇s stability and effect,working process and environment pollution of reducer are described. It is proposed that synthetic consideration on reducer resistivity, its corrosion to grounding object, stability and durability of reducer,environment contamination and cost of reducer. The resistance reducing measures shall be determined on the basis of careful survey and measurement on geographic features and ground resistivity near the grounding obiect.
