Abstract
Reactors produce noise that negatively impacts the environment during their operation. This study focused on vibration and noise reduction in shunt oil reactors through an enhanced design, aiming to mitigate these environmental consequences. Additionally, the precision of measuring vibroacoustic characteristics was enhanced by employing the finite element method. This study utilized the 110–750 kV reactor, POM-60000/525-У1. To minimize noise and vibrations from the active part to the tank, the rubber gaskets’ thicknesses, dimensions, and placements were carefully chosen, considering the magnetic system’s design specifics and pressing forces within the reactor frame. The reactor’s design underwent improvements through modeling and optimization. In the revised design, the number of radiators in the cooling system on both sides and the stiffeners on the reactor tank’s walls were increased, while the reactor’s overall dimensions were preserved. The isosurfaces derived from vibroacoustic testing on the reactor tank model facilitated the processing and visualization of results, thereby validating the model’s accuracy and effectiveness. The average background noise levels of the enhanced reactor were significantly lowered, with the noise difference between the reactor and its surroundings being nearly double that of its existing counterpart. Since noise from wall vibrations and the cooling system impacts reactor lifecycles, reducing these vibrations is crucial for extending the lifespan of the improved reactor.
