摘　　要：文章针对某300MW汽轮发电机组密封油真空油箱磁翻板液位显示始终在某一固定位置,不随油箱实际油位发生变化这一异常现象,对磁翻板液位计、浮子及相关部件进行检查,确定异常原因为磁性液位开关磁性过大所致,并提出解决办法。At some 300 MW steam turbine generator,vacuum sealing oil tank magnetism vane liquid meter fixed a level,and it is not changed as oil tank＇s actual level.In order to resolve this problem magnetism vane liquid meter,floater and related components are checked.Finally it is the level switch which has big magnetic force with the floater.
