| 配电变压器振动与噪声问题日益凸出，研究配电变压器振动与噪声特性对其振动与噪声控制具有重要意义。本文以一台35kV/800kVA油浸式配电变压器为研究对象，对不同激励电压作用下配电变压器铁心振动、油箱振动以及噪声进行测试。测试结果表明：配电变压器铁心、油箱振动与噪声具有相似频谱特征，均表现出以100Hz、200Hz为主要峰值的频谱特征；随着激励电压增加，变压器振动及噪声水平明显增大；变压器油箱振动值大于铁心，侧面振动水平较高，油箱正面和顶面振动水平略低。测试结果准确的反应了配电变压器铁心与油箱的振动与噪声特性，对于其噪声振动控制具有参考价值。 |
| 英文摘要: |
| The vibration and noise problems of distribution transformers are increasingly prominent. Studying the vibration and noise characteristics of distribution transformers are significance for noise control. A 35kV/800kVA oil-immersed distribution transformer is used as the research object. The core vibration, tank vibration and noise of distribution transformer are tested under different excitation voltages. The test results show that core vibration、tank vibration and noise of distribution transformer have similar spectrum characteristics，all of them exhibit spectrum characteristics with 100Hz and 200Hz as the main peaks；As the excitation voltage increases, the transformer vibration and noise levels increase significantly；The vibration value of the transformer oil tank is higher than that of the iron core, the vibration level of the front and top surfaces of the oil tank is slightly lower. The test results accurately reflect the vibration and noise characteristics of the distribution transformer core and oil tank, which have a reference value for its noise and vibration control. |
