| 摘 要： | 在采用240MVA及以上大容量主变的220kV变电站中,主变10kV侧通常设有限流电抗器,以限制10kV母线故障短路电流。本文研究了两种常用的限流电抗器配置方案,通过技术经济比较分析,推荐变电站采用设有总回路限流电抗器的配置方案,并建议取消电抗器前的隔离开关。

| Abstract: | In order to limit short-circuit current at 10kV bus, Current limiting reactor is usually applied at 220kV substation. which each transformer capacity is 240MVA and above. This paper has studied two disposition scheme of this reactor： the total circuit scheme and the separate one. The total circuit scheme is recommended, according to technological and economical comparison. Besides, the canceling of disconnecting switch ahead the reactor is also recommended. |
