Transformer is one of the most important equipment in the power system, and its own health level and operation status will directly affect the safe operation of the entire power system. How to monitor and analyze the vibration and noise of the transformer during operation has attracted more and more attention. Our company has developed a transformer operating state sensor based on vibration and noise. The hardware part aims at the characteristics of the transformer vibration and noise signal, and the real-time data acquisition module. The sensor mainly collects the vibration and noise signal of the transformer during operation.

The product adopts ultra-low power consumption design, radio frequency communication, CRC calibration and other technologies, and is characterized by green environment, maintenance free, complete electrical isolation, convenient installation, strong anti-interference ability, reliable operation, compact size, etc. This product uses the 2.4GHz LoRa wireless communication technology platform, and the communication protocol uses the Internet of Things micro power wireless network communication protocol of the State Grid power transmission and transformation equipment to achieve dual-way communication, realize intelligent management of power equipment operation monitoring, and provide data support for the safe operation of power grid equipment.

Application field: It is applicable to power industry, and is widely used in transformer online monitoring solutions for substations and distribution stations.
