摘要
针对湘钢三中央变电站２２０ｋＶ备用电源自投装置存在的问题，提出了新的方式和设想．分析采用新的方式后，停电时间由３．５ｓ缩短至０．０４～０．０９ｓ的可行性．同时还提出在ＳＦ６断路器的变电站，自投装置应采用的方式．
New modes and suggestions are proposed on the basis of problems of automatic turning on devices of 220kv stand-by power of No. 3 central substation of Xiangtan Iron and Steel Plant. Feasibility of reducing outage time from 3. 5s to 0. 04-0. 09s is analyzed when a new method is used. It proposes suitable modes for automatic turning on devices In a substation with SF6. disconnectors.
