Problems solved by technology

The severe vibration of the reactor not only affects the voltage quality, is not conducive to loss reduction and efficiency increase, but also generates excessive noise
If the reactor group is forced to continue to operate under the condition of severe vibration, it will not only affect the safe production of the power system, cause equipment loss, but also greatly damage the life of surrounding buildings, endangering the production and operation environment

Description

technical field [0001] The invention relates to an on-line vibration monitoring device for a power reactor. Background technique [0002] With the rapid development of our country's economy and the improvement of people's living standards, the scale of the power grid is gradually expanding, and the power load is increasing rapidly. The requirements for power quality are getting higher and higher. The reactor is an important part of the power reactive power compensation complete set, which can compensate the capacitive effect of the long line, limit the voltage rise, maintain the reactive power balance, and play an important role in improving the power supply efficiency of the power grid, improving the voltage quality, and reducing the loss of the power grid. When in use, it is generally a group power reactor switching operation. [0003] Power reactor is an important equipment to ensure the voltage quality of users. Once a failure occurs, it will have a great impact on the ...
