用于变压器的降噪装置、变压器油箱和变压器
摘要：
本发明公开了一种用于变压器的降噪装置、变压器油箱和变压器。该降噪装置包括：降噪板，以及覆于所述降噪板表面的绝缘层；所述降噪板包括：至少两个纸板层，以及设置于相邻纸板层之间的金属板层；并且，所述降噪板的最顶层和最底层均为纸板层。该降噪装置具有成本低且降噪效果好的优点。并且，由于该降噪装置可以设置于变压器油箱内的闲置空间，因此无需避让线路，也无需增大变压器的体积。同时，变压器内壁平直，也有利于简化该降噪装置的结构，使其易于加工以实现工业化生产。
摘要（英）：

The invention discloses a noise reduction apparatus for a transformer, a transformer oil tank and the transformer. The noise reduction apparatus comprises a noise reduction plate, and an insulating layer for covering the surface of the noise reduction plate, wherein the noise reduction plate comprises at least two paperboard layers, and a metal plate layer arranged between adjacent paperboard layers; and in addition, the topmost layer and the lowest layer of the noise reduction plate are both paperboard layers. The noise reduction apparatus has the advantages of low cost and good noise reduction effect; in addition, the noise reduction apparatus can be arranged in an idle space in the transformer oil tank, so that line avoidance and enlarging of the volume of the transformer are not required; meanwhile, the inner wall of the transformer is flat and straight, so that the structure of the noise reduction apparatus can be simplified; and therefore, the noise reduction apparatus is easy to machine and easy to realize industrial production.
