[0022] Referring to Figure 5 As shown in the embodiment, the two sides of the inside of the sliding sleeve 13 are provided with a first sliding groove 17, and the two sides of the sliding rod 15 are fixedly connected with a first sliding block 18. The inside of the first sliding groove 17 is slidably connected with the first sliding block 18. Through the arrangement of the first sliding groove 17 and the first sliding block 18, the sliding rod 15 can be stably limited when sliding in the inside of the sliding sleeve 13, so that the sliding rod 15 will not move excessively, effectively improving the stability during the installation and disassembly of the noise reduction shell 2.

[0023] Referring to Figure 5As shown, in the embodiment: the second sliding groove 19 is arranged on both sides of the fixed block 9, and the second sliding block 20 is fixedly connected to both sides of the buckle 10. The second sliding groove 19 is in sliding connection with the second sliding block 20. The second sliding groove 19 and the second sliding block 20 can guide the buckle 10 to slide in the fixed block 9, so that the buckle 10 does not deviate when being buckled to the clamping groove 7, thereby effectively ensuring the effective installation of the noise reduction shell 2 and improving the stability of noise reduction.

[0024] Referring to Figure 5 As shown, in the embodiment: the surface of the sliding rod 15 is sleeved with an energy storage spring 21. One end of the energy storage spring 21 close to the push-pull plate 16 is fixedly connected to the push-pull plate 16, and the other end of the energy storage spring 21 away from the push-pull plate 16 is fixedly connected to the sliding sleeve 13. When the user presses the push-pull plate 16 to drive the sliding rod 15 to move and then releases the push-pull plate 16, the stored elastic force of the energy storage spring 21 drives the sliding rod 15 to return to the initial position, thereby achieving quick resetting of the sliding rod 15 after movement and facilitating next use.

[0025] Referring to Figure 3 With Figure 5 As shown, in the embodiment: the surface of the buckle 10 is provided with a round corner 22, and the top end of the mounting plate 6 is provided with two contact plates 23. The round corner 22 and the contact plate 23 can make the process of buckling the buckle 10 into the clamping groove 7 more rapid, and the buckle 10 is not prone to shaking after buckling, thereby effectively improving the installation speed and stability of the noise reduction shell 2.

[0026] Referring to Figure 4 As shown, in the embodiment: the rubber pad 24 is arranged at the position where the top end of the base 1 is in contact with the bottom end of the transformer main body 8. The rubber pad 24 can reduce the magnetic vibration between the iron core sheets, effectively reduce the noise of the transformer main body 8, and effectively isolate the vibration of the transformer main body 8 from being transmitted to the foundation and the ground, thereby avoiding resonance.

[0027] Referring to Figure 2 As shown, in the embodiment: the noise reduction shell 2 is made of engineering plastic. The noise reduction shell 2 made of engineering plastic has good heat conduction and sound insulation performance, can quickly conduct the heat generated by the transformer main body 8, effectively reduces the operating temperature of the transformer main body 8, effectively blocks the transmission of the noise of the transformer main body 8, and has a soft texture and a certain sound absorption effect.

[0028] Working principle: when the staff needs to reduce the noise of the transformer body 8, the clamping slot 7 on the mounting plate 6 is buckled into the buckle 10, and the elastic force of the elastic spring 12 makes the buckle 10 firmly clamped in the clamping slot 7, achieving the quick installation of the noise reduction shell 2. When the noise reduction shell 2 needs to be disassembled, press the push-pull plate 16 inward to drive the sliding rod 15 to resist the buckle 10, so that the buckle 10 is disconnected with the clamping slot 7, achieving the disassembly of the noise reduction shell 2. When the noise reduction degree needs to be adjusted, install the noise reduction plate in the slot 4 according to the demand, and adjust the noise reduction degree. By installing different number of noise reduction plates in the noise reduction shell 2, the noise reduction degree of the transformer body 8 can be flexibly adjusted according to different noise reduction needs, so that the transformer body 8 can adapt to various working environments and noise reduction standards. Whether in the city center substation or in the industrial environment such as factory, the noise reduction measures can be easily adjusted according to the specific noise limitation conditions, improving the versatility and adaptability of the transformer body 8. Through the setting of the first sliding groove 17 and the first sliding block 18, the sliding rod 15 can slide stably in the sliding sleeve 13, so that the sliding rod 15 will not move too much, effectively improving the stability of the noise reduction shell 2 during installation and disassembly. Through the setting of the second sliding groove 19 and the second sliding block 20, the buckle 10 can slide stably in the fixed block 9, so that the buckle 10 will not deviate when clamped with the clamping slot 7, effectively ensuring the effective installation of the noise reduction shell 2 and improving the stability of noise reduction. Through the setting of the energy storage spring 21, when the user presses the push-pull plate 16 to drive the sliding rod 15 to move, the push-pull plate 16 is released, and the stored elastic force of the energy storage spring 21 drives the sliding rod 15 to return to the initial position, so that the sliding rod 15 can be quickly reset after moving, which is convenient for next use. Through the setting of the round corner 22 and the contact plate 23, the buckle 10 can be clamped into the clamping slot 7 more quickly, and the clamping is not easy to shake after completion, effectively improving the installation speed and stability of the noise reduction shell 2. Through the setting of the rubber pad 24, the magnetic vibration between the iron core pieces can be reduced, the noise of the transformer body 8 can be effectively reduced, and the vibration of the transformer body 8 can be effectively isolated from the foundation and the ground, avoiding the occurrence of resonance phenomenon. By using the noise reduction shell 2 made of engineering plastic, the heat generated by the transformer body 8 can be quickly conducted away, the operating temperature of the transformer body 8 can be effectively reduced, and the transmission of the noise of the transformer body 8 can be effectively blocked. At the same time, its texture is soft, which has certain absorption effect on sound wave.
