摘要： 箱式变电站由于长期运行屋顶密封不严,开关柜内出现凝露现象并引发跳闸,文中从故障现象发生到如何处理进行了清晰细致的说明,并提出了合理的预防措施及建议。

关键词: 箱式变, 凝露, 预控措施

Abstract: Since the box substation’s roof is sealed untightly after long-term operation,the condensation arises and then causes tripping in the switchgear.The paper explains the breakdown and the management clearly,and puts forward the reasonable preventive measures and suggestions.

Key words: box substation, condensation, pre-control measures
