摘要
文章对用于高土壤电阻率地区的各种降阻措施和原理进行了探讨,并对其适用范围进行了详细分析研究;对工程案例广西220 kV甘陈变电站的实际情况进行了分析,因地制宜对各种措施进行合理和综合的选择,进行了降阻优化设计,使得接地网电阻达到了预期效果和目的;对于高土壤电阻率地区的变电站降阻措施具有较高的工程实际意义和参考价值。
This paper makes a research on some resistance reduction measures and principles for high soil resistivity area and analyzes their application scopes in details.Based on analyses on actual situations of Guangxi 220kV Gan-Chen substation,a reasonable and comprehensive selection on all kinds of resistance reduction measures are carried out in line with local conditions.An optimization design for resistance reduction is presented,which makes the grounding grid resistance achieved the desired effect and has great reference value for reducing substation resistance in high soil resistivity area.
