摘　　要：分析了20kV中压配电输送容量大、供电距离长、电压质量高、输送损耗少的特点，并通过20kV和10kV两个电压等级在贵阳电网部分区域技术经济比较，提出了在贵阳电网推广应用20kV供电的方案，此方案能有效缓解电网建设与土地资源利用的矛盾。This thesis analyzes the characteristics of 20kV medium - voltage distribution network from such several respects as the large capability, long distance, high voltage quality, little loss, etc. And puts forward the plan of promoting and applying the 20kV power supply in Guiyang power grid, by comparing the technology economy in parts of Guiyang power grid between the voltage level of 20kV from 10kV. Finally, it is pointed out that the plan could relieve the contradiction between power grid construction and utilization of land resource.
