摘要

基于变压器铁芯减振技术

建立10 kV油浸式配电变压器物理模型来研究变压器铁芯和油箱的振动机理、传播规律以及阻尼减振效果

分析已安装和未安装铁芯阻尼垫片情况下不同时刻变压器油箱表面振动位移数据。研究证实

可以通过在油箱与铁芯之间增加减振装置

增大振动能量在传递过程中的损耗

降低油箱振动幅度与噪声排放。根据变压器油的特点和应用需要

选择软木橡胶、丁腈橡胶和氟橡胶三种典型阻尼材料进行了耐油性能测试

结果表明三种橡胶的耐油性能均满足要求。减振性能测试结果表明

软木橡胶与丁腈橡胶不满足变压器本体噪声抑制条件

且在带负载条件下会一定程度增大噪声;氟橡胶减振垫满足变压器振动噪声抑制要求

能有效减小噪声

可作为潜在的油浸式变压器铁芯减振垫材料。

Abstract

A physical model of 10 kV oil-immersed distribution transformer is established to study the vibration mechanism

transmission law and damping effect of transformer core and oil tank

the vibration displacement data of transformer oil tank surface at different time with and without iron core damping gasket are analyzed. It is proved that the vibration amplitude and noise emission of oil tank can be reduced by adding damping device between oil tank and iron core to increase the loss of vibration energy in the process of transmission. According to the characteristics and application requirements of transformer oil

cork rubber

nitrile rubber and fluorine rubber were selected to test their oil resistance. The test results of damping performance show that cork rubber and NBR can not satisfy the noise suppression condition of transformer

and will increase the noise to some extent under the condition of load

the fluorine rubber damping pad can meet the requirements of vibration and noise suppression of transformer

and can effectively reduce the noise. It can be used as a potential damping pad material for oil-immersed transformer iron core.
