霍尔电流传感器故障引起的励磁系统故障

On an Excitation System Failure Caused by Hall Current Sensor Fault

针对某电厂励磁系统发故障报警,经过多次排查分析,最终找出故障原因为5号整流柜负极霍尔电流传感器因磁饱和导致测量失真。此励磁系统故障处理过程可为其他励磁系统用户提供借鉴。

In response to a fault alarm in the excitation system of a certain power plant,multiple investigations and analysis are carried out,based on which it is ultimately found that the fault is caused by measurement distortion due to magnetic saturation of the negative Hall current sensor of the 5th rectifier cabinet.Such an excitation system fault handling process is availablel to offer reference for other excitation system users.
