封闭开关柜中熔断器过热烧坏分析

The melting of high voltage fuse in swith cabinet of box type transformer

针对箱变封闭开关柜中熔断器过热烧坏的问题,从熔断器发热功率方面进行了分析,解决了夏季高峰负荷时熔断器过热爆炸的问题,达到了夏季高峰负荷时稳定供电的效果。

The paper analyze the melting of high-voltage fuse in switch cabinet of box-type transformer and point out the main reason lies in the thermal power of fuse. Thus solving the problem of explosion of fuse during the peak time of summer and improving the reliability of lower supply.
