[0027] With the above structure, after the dry-type transformer body 1 and the connecting block 2 are placed inside the placement groove 2 6 opened inside the fixing plate 2 5, the connecting block 2 can be fit into the placement groove 2 6. When the dry-type transformer body 1 vibrates during operation, the elastic force of the telescopic spring 1 8 installed at the left and right ends of the placement groove 2 6 can make the connected rubber block 9 elastically recover the generated left and right vibration force to reduce the amplitude of the vibration.
[0028] Furthermore, a thread groove 13 is provided inside the placement groove 4, and four thread grooves 13 are regularly provided along the interior of the placement groove 4. A noise reduction box 14 is inserted and installed inside the placement groove 4. The noise reduction box 14 is a square shape with a hollow interior. Ventilation holes 15 are provided at the front and rear ends of the noise reduction box 14, and thread grooves 2 16 are provided on the outer walls of the left and right ends of the noise reduction box 14.

At this time, by rotating the threaded rod 21, the noise reduction box 14 can be quickly engaged and fixed. Moreover, the noise reduction box 14 is made of a sound-insulating sponge material, which can further insulate and reduce the noise of the dry-type transformer body 1 after installation.

At this time, after rotating the threaded rod 19, the filter cover 17 can be quickly installed on the outer wall of the noise reduction box 14, so that the dry-type transformer main body 1 can be subjected to noise reduction treatment without affecting the ventilation and heat dissipation effect of the dry-type transformer main body 1, and the filter cover 17 can be quickly disassembled and assembled to clean the filter cover 17 to prevent dust accumulation from affecting the ventilation and heat dissipation effect of the dry-type transformer main body 1.
