| 摘 要： | 沙塘湾110kV变电站所区的平均土壤电阻率过高，采用常规水平接地网方案时，其接地电阻值远不能达到标准的要求。针对此种情况，提出采用扩大水平接地网、深井接地、方孔均压网与不等间距布置相结合的方式对接地网进行优化，有效地降低了接地电阻，同时提出通过二次系统的接地方案来提高变电站电磁兼容水平，较好地满足了变电站对接地网的技术要求。 |
| 关 键 词： | 变电站 接地网 优化设计 二次系统接地 |

| Abstract: | The average soil resistance rate is too high at Shatangwan 110kV substation area. If conventional horizontal ground net is applied,its ground resistance value can not meet the standard. Pointing to the case,the paper puts forward that the ground net will be optimized through horizontal ground net expansion,deep-well grounding,combination of square-hole equalizing net and unequal gap arrangement to reduce ground resistance effectively. It also suggests that substation electromagnetic compatible level can be ... |
