Design and implementation of a distributed vibration monitoring system for power transformer
Power transformer plays an important role in the power system. The traditional transformer fault detection method has the disadvantages of large construction difficulty and low sensitivity. By collecting the vibration information of the transformer, online and more accurate monitoring of the transformer operating status can be achieved. The existing vibration acquisition systems are mostly integrated design, which cannot guarantee the diversity and accuracy of the information. This paper designed a distributed transformer vibration monitoring system, which can collect a variety of types and multi-channel signals, and has strong expansion performance. Effectively avoid signal interference in the station. By installing the vibration acquisition unit on the side of the transformer, the collected vibration signal is digital-analog converted and sent to the upper computer for analysis and processing. The online monitoring of the working state of the transformer can be realized, and the transformer winding can be diagnosed whether it is deformed. The corresponding vibration acquisition system was designed and installed for the Guangzhou substation on the ground, and it has been successfully put into use.
