  • System for perceiving operating state of large power transformer based on vibro-acoustic integration
    Patent number: 11815565
    Abstract: The present disclosure provides a system for perceiving an operating state of a large power transformer based on vibro-acoustic integration, including a perception layer, a network layer, and a diagnostic layer, where the perception layer is used for monitoring, in real time, a state parameter for a coupling vibration signal and an acoustic signal of each of a transformer core, a winding, a clamp and a housing, a state parameter of each of a vibration signal and an acoustic signal during a gear position change of an on-load tap changer (OLTC), and preliminarily diagnosing and analyzing monitored data. The system can monitor the operating state of the OLTC online for a long time, flexibly configure the sensor channel and the sensor type according to different application requirements, automatically acquire and identify the gear position change, and correctly identify and process a gear position corresponding to the monitoring signal.
