Abstract: The dry-type transformers have vibration and noise problems during operation. In order to study
the vibration rules and characteristics of dry-type transformer, the mechanism of vibration and noise gener-
ation of dry-type transformer were studied and simulated. The finite element simulation model of dry-type
transformer vibration was established. The corresponding magnetic field distribution was obtained by electro-
magnetic analysis, and then the structural vibration was used to obtain the relevant laws of its vibration. The
characteristic frequency of transformer vibration was obtained through the measured analysis of transformer
vibration data in operation state. The characteristic frequency of transformer vibration was found by com-
paring and analyzing the simulation results. The results can provide a reference for the research of vibration
reduction of dry-type transformers.
