Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention 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 the bottom of outer container 1 is fixedly mounted noise reduction and subtracted
Plate 4 is shaken, 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, noise reduction vibration damper plate
Base 6 is fixedly mounted below 4, noise reducing plate 3 and base 6 are honeycomb, and base 6 is the structure that section is in concave,
One end of fix bar 7 is 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, drop
Make an uproar and several through holes 9 are set on ball 8, several through holes 9 communicate with each other, and acoustical panel 10, acoustical panel 10 is fixedly mounted in the inner chamber of through hole 9
Liner plate 11 is fixedly mounted in undulate structure, the inwall of base 6, and liner plate 11 is the trapezoidal structure of section, is fixed on liner plate 11
Some pieces of reflecting plates 12 are installed, the angle of inclination of each reflecting plate 12 differs, and above outer container 1 and side is fixedly mounted
Spring 13, the one end of spring 13 away from outer container 1 are fixedly connected with arc 14, and some reflecting plates 12 are fixedly mounted on arc 14,
The outside of outer container 1 sets silencer cover 19, and the side wall of silencer cover 19 sets several hush pipes 20, and hush pipe 20 is U-shaped structure, is disappeared
The both ends of sound tube 20 are arranged at the inwall of silencer cover 19, and the both ends of hush pipe 20 are fixedly connected with horn mouth 21, hush pipe 20
Acoustical panel 10 is fixedly mounted in inwall, and the top of outer container 1, interior case 2 and noise reducing plate 3 is provided with perforation 15, and the top of outer container 1 is fixedly mounted
