N2 - The gas insulated switchgear (GIS) vibrates during operation. To analyze the impact of harmonic components in the power grid on the vibration characteristics of the GIS. This paper analyzes the vibration mechanism of the GIS busbar shell, and the relationship between the vibration-related physical quantities and excitation current is established. In addition, the vibration test platform is established based on the existing GIS single-phase bus barrel model in the laboratory, and the vibration characteristics of the GIS at different measuring point and under the excitation of multi-frequency sinusoidal current are measured. The measurement results indicate that the vibration amplitude of the GIS shell is roughly symmetrically distributed in the axial direction, and the main vibration acceleration frequency is twice the frequency of the excitation current. When multiple harmonic currents coexist, its vibration frequency is more abundant, and it is easier to cause mechanical resonance.
