AI Technical Summary
After long-term use, the rubber shock absorbing pads in existing oil-immersed substation equipment have reduced elasticity and are unable to effectively absorb shock and noise, resulting in increased equipment vibration and noise levels.
A shock-absorbing and noise-reducing structure is designed, including a cladding layer and a damping rubber layer embedded in the cladding layer. The damping rubber layer is composed of a main layer, a filling layer, a plasticizing layer, a vulcanizing layer and an aging layer. The plasticizing layer is composed of a material with a damping coefficient of 0.45-0.58 Newtons/meter.
By improving the elasticity of the rubber shock absorbing pad, more effective shock and noise reduction effect is achieved, reducing the vibration and noise level of the equipment.
