Abstract

The invention relates to the technical field of transformer monitoring and particularly relates to a transformer voiceprint vibration monitoring system based on the Internet of Things technology. The system comprises a plurality of vibration sensors, three PT transformers, three CT transformers, a neutral point current sensor, a multi-channel acquisition board, a communication module and a server, wherein a plurality of vibration sensors are distributed and installed on the transformer shell, the neutral point current sensor is coupled with a neutral line to monitor current signals in the neutral line, and the plurality of vibration sensors, the three PT transformers, the three CT transformers and the neutral point current sensor are all connected with the multi-channel acquisition board; and the multi-channel acquisition board is in communication connection with the server through the communication module. The transformer vibration voiceprint acquisition system is advantaged in that vibration signals of the transformer shell are acquired through the vibration sensor, the multi-channel acquisition board acquires the vibration signals and sends the vibration signals to the server, online acquisition of transformer vibration information is achieved, and the server performs data processing and analysis to obtain the vibration voiceprint of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformer monitoring, in particular to a transformer voiceprint vibration monitoring system based on Internet of Things technology. Background technique [0002] Transformer is an important equipment for power transmission and transformation. Iron core and winding are the core components of the transformer. Due to mechanical fatigue and manufacturing process problems caused by the long-term operation of the transformer, the inner iron core of the transformer will loosen and the compression force of the winding coil will decrease. There is a high probability that the winding will be deformed if there is a short circuit impact! Once the winding of the transformer is deformed, it will leave hidden troubles and cause major accidents at any time. At present, transformer winding deformation faults occur frequently. Since the internal mechanical loosening of transformers and winding deformation are mechanical...
