| Abstract: | This paper analyzes the reason for Meizhou county power plant sixth unit No. 4 bearing Y direc- tion vibration signal mutation Guangdong Yue Jia Electric Power Co. , Ltd. Finally it is confirmed that vi- bration probe extension cable 1 meter layup exists budge phenomenon, which causes signal sometimes bad contact, which is the reason why the vibration signal mutates. The fault phenomenon is eliminated after re- placing the probe. |
