摘要
对 2台变压器供电的变电站备用电源自动投入方式进行了分析 ,说明了现有的备用电源自动投入装置在供电可靠性和经济性中的矛盾和问题 。
The switching mode of internal bridge connected automatic standby power supply for substations with two transformers is analyzed in this paper. It is pointed out that there exists contradiction between reliability and economy and some other issues when the current switching device is used.
