摘要
文章介绍了宝钢一～三期低压供电系统的几种主接线形式和变压器的中性点 5 1GN继电保护。分析了部分主接线设计中存在的问题和现场发生的变压器跳电原因 。
Different single diagrams of the low voltage power system and the 51GN relay protection of tranformer of PhaseⅠ～Ⅲ at Baosteel are presented.A thorough study is made on the design problems in partial system and the power down fault of transformer.The problems can be solved by installing electric blocking.
