火力发电机组机端电压互感器一次保险熔断分析与研究

摘要

根据某电厂机组的实例可以看出，发电机机端电压互感器一次保险熔断或接触不良，对机组的正常运行有很大危害，直接会影响测量、计量、保护等二次设备动作准确性，甚至导致非停事故的发生。必须采取必要的防范措施，确保机组安全稳定运行。%According to the example of a power plant, it can be seen that the power of generator terminal voltage transformer has a great harm to the normal operation of the unit,which will cause the accuracy of measurement,measureme nt,protection,etc.,and even lead to the occurrence of the accident.Must take necessary precautions to ensure the safety and stabilityof the unitoperation.
