Sound absorbing and noise reducing material and transformer vibration isolating and noise reducing device

Abstract

The invention provides a sound absorbing and noise reducing material and a transformer vibration isolating and noise reducing device. The sound absorbing and noise reducing material mainly comprises asphalt, organic silicon, micro-pore ceramic and micro-pore glass balls; the asphalt and organic silicon are mixed filler; the mixed filler and the micro-pore ceramic and micro-pore glass balls as sound absorbing raw materials are mixed according to the following weight percentage: 20-90% of asphalt and organic silicon and micro-pore ceramic mixed filer is mixed with 10-80% of micro-pore ceramic and micro-pore glass balls mixed material, to form the sound absorbing and noise reducing material with a certain strength and binding property. The transformer vibration isolating and noise reducing device is arranged on at least one vibration damping base of the lower part of a transformer body by a group of dampers, and is characterized in that the damping base is pre-formed on a ground base, and sound absorbing and noise reducing materials integrated with the ground base are spread on four sides of the damping base. The sound absorbing and noise reducing material and a transformer vibration isolating and noise reducing device have the characteristics of wide source of raw materials, low cost, easy manufacturing, reasonable structure of device, convenient construction and the like.

Description

technical field [0001] The invention relates to a sound-absorbing and noise-reducing material and a transformer vibration-isolation and noise-reducing device, which belong to the technical field of vibration-damping materials and vibration-damping devices. Background technique [0002] With the increasing scale of urbanization in our country, the number of transformers and other power transmission and transformation equipment installed in urban and rural residential quarters and commercial areas is also increasing day by day, and most of the power transmission and transformation equipment such as transformers are directly placed in residential quarters or very close to the residence. place. However, the transformer is prone to the following problems during operation: 1. The transformer often produces serious environmental vibration and noise pollution problems during operation; noise. This directly affects the normal life of the residents, and even causes discomfort in...

However, the transformer is prone to the following problems during operation: 1. The transformer often produces serious environmental vibration and noise pollution problems during operation; noise

[0004] The above-mentioned prior art transformer vibration isolation and noise reduction base can isolate the transmission of solid-borne sound, but there are the following problems: first, installation is more troublesome, and does not have the performance of moisture-proof and anti-corrosion, the service life of the base is short, and the cost is high; 2. The base cannot effectively reduce the high and low frequency vibration of the transformer body, and the vibration reduction effect is not obvious
