无刷励磁机旋转二极管非导通检测系统故障分析

Analysis of Non-Conduction Detection System Fault in Brushless Exciter Rotary Diode

介绍某发电厂旋转二极管非导通检测系统(DNC)的基本原理,分析和探讨该检测系统发出报警信号及跳闸信号后的处理方法。提出非导通检测系统的薄弱环节在于传感器CAPT,对投运时间较长的传感器要做定期的动态波形分析,以便及时发现和处理缺陷。

This paper introduce the main principle of the generator diode non conduction detection system of one power station,analysis and discussion procedure when a failure of the system is signaled.It proposes the weak link of DNC is sensor CAPT,and makes dynamic waveform analysis to sensor which put into service for a long time.
