Abstract:  In order to solve the problem of the equipment noise and vibration in a substation reactor, finite element analysis model of the reactor was established by numerical simulation method. The modal and harmonic response analysis also were completed using ANSYS software. It was concluded that the main reason causing vibration and noise is the basis of the reactor failed to isolating vibration that producing lowfrequency noise. Therefore the improved method increasing rubber vibration isolator between the base and equipment was proposed. Comparing with the original equipment, the improved structure shows that reduction effect of vibration and noise is obvious.
