Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Figure 1 to Figure 3 It shows an embodiment of the oil-immersed transformer based on the magnetic damping sound insulation board of the present invention. In this embodiment, the damping sound insulation board is installed and tested on a scale model of a 110kV test transformer. The damping sound insulation board is installed and tested. The sound board 2 is installed between the oil tank shell 1 of the transformer and the heat sink 4, and is fixed on the sides 13 of the oil tank shell 1 of the transformer by strong magnets; the structure of the damping sound insulation board 2 is composed of two layers of aluminum layers and a flexible sound insulation layer 22, the flexible sound insulation layer 22 is placed between two aluminum layers, the two damping sound insulation panels 2 adjacent to the same side 13 are overlapped by...
