摘要(Abstract)：

对各种双母接线二次电压切换回路的优缺点作了分析,结合故障实例,对缺陷回路进行了分析并提出了改进建议,提高了电压切换回路的可靠性。
With the continuous development of relay protection technology and sophisticated,voltage switch circuit has also experienced a number of technical updates,but still insufficient,especially when non-normal secondary voltage juxtaposition will easily lead to secondary side circulation,or under special operating mode in the secondary to an anti-charging,causing the air switch tripping operation,Furthermore,the whole transformer substation may lose voltage under another fault. For the existing hidden trouble of the voltage switch circuit,the detailed analysis is made in this paper. Also,some corresponding measures are brought forth,which can improve the reliability of voltage switch circuits and the operation of transformer substations. The actual operation of the substation has a high practical value.
