[0024] It should be noted that the four shock-absorbing structures 3 can be used to reduce the vibration of the special transformer, so as to prevent the vibration caused by the operation of the device from generating noise and affecting the hearing health of the staff.

[0025] See also Figure 2-4 In order to facilitate the replacement of the desiccant, in this embodiment, the connecting mechanism 5 includes a fixing port 501 opened on the left and right sides of the upper surface of the protective shell 4, a frame 502 is fixed inside the fixing port 501, a circulation support net 503 is fixed on the lower side of the frame 502, a drying bag 504 is placed on the upper surface of the circulation support net 503, a sealing cover 505 is fixed to the upper surface of the frame 502 by bolts, and connecting pipes 506 are fixed on the left and right sides of the protective shell 4. When it is necessary to replace the drying bags 504 inside the two frames 502, the bolts on the upper surfaces of the two sealing covers 505 can be twisted with a screwdriver, and then the two sealing covers 505 can be removed. At this time, the drying bags 504 inside the two frames 502 can be taken out by hand and replaced, and the air inside the protective shell 4 can be dried by the drying bags 504 inside the left and right frames 502.

[0026] In this embodiment, the opposite sides of the left and right connecting tubes 506 pass through the left and right sides of the protective shell 4 and are connected to the opposite sides of the left and right frame bodies 502. The outer threaded seal at the bottom end of the connecting tube 506 is connected to a conical tube 507. A filter screen 508 is fixed inside the conical tube 507.

[0031] When it is necessary to replace the drying bag 504 inside the two frames 502, the bolts on the upper surfaces of the two sealing covers 505 can be twisted with a screwdriver, and then the two sealing covers 505 can be removed. At this time, the drying bags 504 inside the two frames 502 can be taken out by hand and replaced. The drying bags 504 inside the left and right frames 502 can dry the air inside the protective shell 4 to improve the dryness of the special transformer. The four shock-absorbing structures 3 can reduce the vibration of the special transformer to prevent the device from generating noise due to vibration during operation. Noise affects the hearing health of the staff. By turning on the heat dissipation fan 509, the air dried inside the left frame 502 flows into the inside of the air outlet plate 512 through the input pipe 510 and the output pipe 511. The air outlet plate 512 evenly discharges air and dissipates heat to the special transformer body 2. The air flowing inside the protective shell 4 can be discharged through the right circulation support net 503, the frame 502, the connecting pipe 506 and the tapered pipe 507, and can also be discharged through the left connecting pipe 506 and the tapered pipe 507, thereby improving practicality.
