摘　　要：电压互感器是水电厂自动化控制系统重要的一环,电压互感器一次保险熔断后,对发电机的安全运行有着很大的影响。一次保险熔断的原因有很多种,需从设备质量、检修工艺、运行管理等方面去解决,同时出现一次保险熔断情况时,要尽可能利用已有的监视设备尽早发现设备隐患,及时消除缺陷,避免故障扩大。Voltage transformer is an important part of automatic control system in hydropower plant.The primary fuse fusing of voltage transformer has a great influence on the safe operation of generator.There are many reasons for fuse fusing,which need to be solved from the aspects of equipment quality,maintenance process,operation management and so on.At the same time,when a fuse fusing occurs,the existing monitoring equipment should be used as soon as possible to find the hidden dangers of the equipment,eliminate the defects in time and avoid the expansion of the fault.
