AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.
