摘　　要：介绍了 5 0 0kV东莞变电站电气主接线 ,通过技术、经济比较 ,进行了 5 0 0kV和 2 2 0kV电气接线方案论证。得出结论 :5 0 0kV采用一台半断路器接线 ,2 2 0kV采用双母线单分段带旁路接线 ,设单旁路、双母联断路器 ,35kV采用单母线单元接线。The main electric connection schemes of 500 kV Dongguan Substation is described. Through technical and economic comparison, schemes for 500 kV and 220 kV electric wiring are demonstrated. It is suggested that the breaker and a half configuration be adopted for 500 kV, the singly sectionalized double bus configuration with auxiliary bus and single by pass, double bus coupling circuit breaker for 220 kV, and the single bus unit configuration for 35 kV.
