Measurement and Analysis of Vibration Characteristic of 1000kV Reactor tank

In order to obtain the vibration characteristics of 1000kV reactor, the acceleration signals of 1000kV three-phase reactor tank are fully measured. The analyses show that vibration energy of transformer concentrates on 100Hz, and the total vibration speed level can be equal to the 100Hz component with an error less than 1%. As the asymmetry of the reactor structure will affect its vibration distribution characteristics, the vibration distribution and the average vibration speed level of the four faces of the tank are different. Thus, the vibration and noise reduction and sound source modeling should be dealt separately of each tank face. The vibration of the reactor tank shows that vibration is stronger when the measuring point is closer to the middle position , and vibration of the stiffener structure is much smaller than that of the adjacent flat structure. It can be seen that the reinforcement can effectively reduce the vibration of the tank.
