In order to monitor the abnormal state of an Ultra-high Voltage (UHV) reactor in real-time, vibration monitoring device was installed with vibration displacement, velocity and acceleration sensors attached on the equipment shell. It is detected that there is a non-core vibration source on the downlead side of the X-pillar iron core during the acetylene growth period. The disintegration results show that there is a significant phenomenon of discharge ablation on the downlead side of the X pillar ground-shield, which agrees with the analysis of vibration monitoring. It is proved that the vibration monitoring method is effective in the analysis and diagnosis of electrical equipment defects.
