Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of noise reduction oil-immersed power transformer, including
Outer container 1, the inner chamber of outer container 1 set in case 2, noise reducing plate 3 is set between outer container 1 and interior case 2, and drop is fixedly mounted in the bottom of outer container 1
Make an uproar vibration damper plate 4, noise reduction vibration damper plate 4 is hollow structure inside, and the inner chamber of noise reduction vibration damper plate 4 sets several sponge blocks 5, and noise reduction subtracts
Shake and base 6 is fixedly mounted below plate 4, noise reducing plate 3 and base 6 are honeycomb, and base 6 is the knot that section is in concave
Structure, one end of fix bar 7 being fixedly connected among the bottom of noise reduction vibration damper plate 4, the other end of fix bar 7 is fixedly connected with noise reduction ball 8,
Several through holes 9 are set on noise reduction ball 8, and several through holes 9 communicate with each other, and acoustical panel 10, acoustical panel is fixedly mounted in the inner chamber of through hole 9
Liner plate 11 is fixedly mounted in 10 undulate structures, the inwall of base 6, and liner plate 11 is the trapezoidal structure of section, is consolidated on liner plate 11
