DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figures 1-6 The utility model provides a technical scheme: a kind of efficient shock-absorbing dry-type power transformer, including transformer body 1, connecting plate 2, bottom plate 3, fixed rod 4, communication rod 5, spring 6, pressing block 7, connecting frame 8, arc spring piece 9, buffer bag 10, fixed groove block 11, sliding rod 12, rotating plate 13, support plate 14.

[0031] Embodiment 1: the efficient shock-absorbing dry-type power transformer is provided with shock-absorbing structure, can reduce the vibration of transformer body 1, avoids internal parts damage, specifically:

[0032] A connecting plate 2 is fixedly installed on the lower surface of the transformer body 1, and a base plate 3 is also included. A fixing rod 4 is fixedly installed on the upper surface of the base plate 3. A shock-absorbing structure is connected to the base plate 3. The shock-absorbing structure can reduce the vibration of the transformer body 1 quickly by pressing the buffer bladder 10 through the pressure block 7. The shock-absorbing structure includes a connecting rod 5, which is installed through the upper surface of the connecting plate 2. The lower surface of the connecting rod 5 has an opening through which the fixing rod 4 slides. The upper end of the fixing rod 4 is connected to a spring 6, and the upper end of the spring 6 is fixedly installed on the upper surface of the inner wall of the connecting rod 5. A pressure block 7 is fixedly installed on the lower surface of the connecting plate 2. The lower end of the pressure block 7 corresponds to the position of the opening on the upper surface of the connecting frame 8. The connecting frame 8 is fixedly installed on the upper surface of the base plate 3. An opening is provided on the outer surface of the connecting frame 8. An arc-shaped spring piece 9 is fixedly installed in this opening. A buffer bladder 10 is fixedly installed on the bottom surface of the inner wall of the connecting frame 8. The lower surface of the pressure block 7 corresponds to the position of the upper surface of the buffer bladder 10. Two connecting frames 8 are symmetrically arranged.

[0033] When this high-efficiency vibration-damping dry-type power transformer is in use, the base plate 3 is fixedly installed in the installation position. When the transformer body 1 is turned on, vibration will be generated, such as... Figure 4 As shown, this will cause the connecting plate 2 to press downwards, causing the two pressure blocks 7 installed on the lower surface of the connecting plate 2 to slide downwards in the connecting frame 8. Since a buffer bladder 10 is fixedly installed on the inner wall of the connecting frame 8, the buffer bladder 10 will be squeezed downwards. When the buffer bladder 10 is squeezed, its outer surface will expand, as shown. Figure 2 As shown, the arc-shaped spring piece 9, which is fixedly installed on the outer surface of the connecting frame 8, corresponds to the outer surface of the buffer bag 10. Therefore, the buffer bag 10 will squeeze the arc-shaped spring piece 9, thereby further buffering the vibration. The upper end of the fixing rod 4, which is fixedly installed on the upper surface of the base plate 3, slides through the upper surface of the connecting plate 2 and enters the connecting rod 5. The connecting rod 5 can prevent the connecting plate 2 from displacing during vibration. At the same time, the spring 6 connected to the upper end of the fixing rod 4 and the upper surface of the inner wall of the connecting rod 5 can buffer the amplitude. Since the spring 6 is inside the connecting rod 5, the constraint of the connecting rod 5 can prevent the spring 6 from resonating, making the whole more stable. Furthermore, the arc-shaped spring piece 9 and the buffer bag 10 can also reduce vibration noise and reduce the impact of vibration and collision on the internal components of the transformer.

[0034] Example 2: This high-efficiency vibration-damping dry-type power transformer is equipped with a support structure. The support plate 14 increases the support area of ​​the transformer body 1, making the transformer body 1 more stable. Specifically:

[0035] The connecting plate 2 is connected to a support structure. The support structure can move the support plate 14 to support the ground via the sliding rod 12. The support structure includes a fixed groove block 11, which is embedded in the lower surface of the connecting plate 2. The sliding rod 12 is slidably installed on the inner wall surface of the fixed groove block 11. The rotating plate 13 is rotatably installed on the outer surface of the sliding rod 12. The rotating shaft of the support plate 14 is rotatably installed on the inner side surface of the rotating plate 13. The support plate 14 corresponds to the slotted position on the lower surface of the fixed groove block 11. The lower surface of the support plate 14 is provided with anti-slip particles.

[0036] Furthermore, such as Figure 5 As shown, a fixing slot 11 is installed when embedded in the lower surface of the connecting plate 2, and four fixing slots 11 are installed. Pulling the support plate 14 outward will cause the support plate 14 to drive the rotating plate 13 to move, so that the rotating plate 13 drives the sliding rod 12 to slide on the inner wall surface of the fixing slot 11. Since the rotating plate 13 is rotatably installed on the outer surface of the sliding rod 12, rotating the rotating plate 13 downward will cause the support plate 14, which is rotatably installed on the inner surface of the rotating plate 13, to rotate, so that the lower surface of the support plate 14 contacts the ground. The anti-slip particles on the lower surface of the support plate 14 can enhance the friction with the ground. The support plate 14 and the rotating plate 13 support the transformer body 1, making the transformer body 1 more stable, improving the overall stability, better maintaining balance, reducing the risk of tipping over, and distributing the weight of the transformer body 1 more evenly on the ground, reducing damage caused by excessive local pressure, reducing the risk of the transformer tilting, shifting or even tipping over due to external forces, and ensuring that the transformer can operate safely and reliably under various environmental conditions.

[0037] Working principle: When using this high-efficiency vibration-damping dry-type power transformer, a vibration-damping structure is set up. The arc-shaped spring sheet 9 and the buffer bag 10 can reduce the vibration of the transformer body 1 and avoid damage to internal parts. A support structure is also set up. The support plate 14 contacts the ground to increase the support area of ​​the transformer body 1, making the transformer body 1 more stable and increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
