Description

Technical Field

[0001] This utility model relates to the field of transformer-related technology, and in particular to a seismic protection device for power transformers. Background Technology

[0002] As one of the main power transmission and transformation equipment in a substation, the transformer holds a core position within the substation. It can be said that the transformer is the heart of the substation. The condition of the transformer directly affects the entire substation. Therefore, a seismic protection device for power transformers is particularly needed.

[0003] However, existing transformers and traditional transformer seismic protection devices mostly adopt rigid support structures, which are difficult to effectively disperse the impact energy in different directions when encountering seismic waves, and are prone to stress concentration leading to equipment displacement. The heat dissipation system usually relies on natural convection heat dissipation. Under the condition of equipment vibration caused by continuous earthquakes, the heat sink is prone to structural deformation, resulting in a sharp drop in heat dissipation efficiency. This affects the operational safety and service life of the transformer. Utility Model Content

[0004] The purpose of this utility model is to provide a seismic protection device for power transformers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power transformer anti-vibration protection device, comprising a transformer body, a protective mechanism provided on the upper surface of the transformer body, and a cooling mechanism provided on one side surface of the transformer body;

[0006] The protective mechanism includes a base, a first spring, a protective plate, a fixed plate, a connecting plate, a swing block, a second spring, and a fixed shaft. The transformer body is provided with a base, the base is provided with a first spring, one end of the first spring is fixed with a protective plate, a fixed plate is installed on the outer wall of the protective plate, a connecting plate is provided inside the fixed plate, a swing block is installed at one end of the connecting plate, a second spring is fixed at one end of the swing block, and a fixed shaft is provided inside the second spring.

[0007] Preferably, the cooling mechanism includes a water pump, a water supply pipe, a water tank, a water outlet pipe, and a circulating water pipe. The water pump is installed on the outer wall of the transformer body. A water supply pipe is installed at one end of the water pump. A water tank is fixed at one end of the water supply pipe. A water outlet pipe is installed at one end of the water pump. A circulating water pipe is fixed at one end of the water outlet pipe.

[0008] Preferably, the first spring and the protective plate form a telescopic structure, and the swing block and the second spring form a telescopic structure.

[0009] Preferably, there are two swing blocks, which are arranged symmetrically about the length centerline of the protective plate.

[0012] Preferably, the circulating water pipe is sleeved on the outer wall of the transformer body, and one end of the circulating water pipe is connected to the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This type of seismic protection device for power transformers, through the installation of a protective mechanism, allows for initial buffering of the vibrations experienced by the transformer body during an earthquake. The protective plate, under the elastic force of the first spring, initially cushions the vibrations. Simultaneously, the swing block, under the elastic force of the second spring, pushes the fixed plate to swing via the connecting plate, further buffering the vibrations and preventing stress concentration that could lead to equipment displacement, thus improving the safety and stability of the transformer's operation. A cooling mechanism is also included. When the internal temperature of the transformer rises, a water pump starts, delivering coolant from the tank to the circulating water pipe. The coolant absorbs the heat generated by the transformer as it flows through the circulating water pipe. The coolant then returns to the tank through the outlet pipe, where it is cooled, forming a complete heat dissipation cycle. This improves the transformer's heat dissipation efficiency, prevents damage from high temperatures, and extends the transformer's service life. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a power transformer anti-vibration protection device, including a transformer body 1, a protection mechanism 2 provided on the upper surface of the transformer body 1, and a cooling mechanism 3 provided on one side surface of the transformer body 1.

[0022] The protective mechanism 2 includes a base 21, a first spring 22, a protective plate 23, a fixing plate 24, a connecting plate 25, a swing block 26, a second spring 27, and a fixed shaft 28. The transformer body 1 is provided with a base 21, and a first spring 22 is mounted on the base 21. One end of the first spring 22 is fixed to the protective plate 23. A fixing plate 24 is installed on the outer wall of the protective plate 23. A connecting plate 25 is provided inside the fixing plate 24. A swing block 26 is installed at one end of the connecting plate 25. A second spring 27 is fixed at one end of the swing block 26. A fixed shaft 28 is provided inside the second spring 27. The structure is connected via the base 21, the first spring 22, the protective plate 23, the fixing plate 24, the connecting plate 25, the swing block 26, and the second spring 28. The arrangement of 7 and fixed shaft 28 allows the protective mechanism 2 to buffer and protect the transformer body 1 during an earthquake, preventing it from being subjected to excessive impact. When impacted, the protective plate 23 is first subjected to force, at which point the first spring 22 will extend and retract, providing initial buffering. Simultaneously, the swing block 26 is subjected to force and swings horizontally around the fixed shaft 28, at which point the second spring 27 will extend and retract, further providing buffering. This increases the stability of the transformer body 1 during an earthquake. Through the arrangement of the protective mechanism 2, the impact energy of seismic waves on the transformer body 1 is effectively dispersed, preventing displacement and improving the safety of the transformer body 1 during an earthquake.

[0023] Furthermore, the cooling mechanism 3 includes a water pump 31, a water supply pipe 32, a water tank 33, a water outlet pipe 34, and a circulating water pipe 35. A water pump 31 is installed on the outer wall of the transformer body 1. A water supply pipe 32 is installed at one end of the water pump 31, and a water tank 33 is fixed to one end of the water supply pipe 32. A water outlet pipe 34 is installed at one end of the water pump 31, and a circulating water pipe 35 is fixed to one end of the water outlet pipe 34. Through the arrangement of the water pump 31, water supply pipe 32, water tank 33, water outlet pipe 34, and circulating water pipe 35, the transformer body 1 can be cooled in a timely manner when its temperature rises. After the water pump 31 starts, it delivers the coolant from the water tank 33 to the corrugated radiator through the water supply pipe 32. As the coolant flows in the corrugated radiator, it absorbs the heat generated by the transformer body 1 and returns to the water tank 33 through the water outlet pipe 34 and the circulating water pipe 35 for cooling circulation. This cooling method not only has high heat dissipation efficiency but also ensures the stable operation of the transformer body 1 in high-temperature environments.

[0024] Furthermore, the first spring 22 and the protective plate 23 form a telescopic structure, and the swing block 26 and the second spring 27 form a telescopic structure. With the setting of the protective plate 23, the protective plate 23 can be moved when the first spring 22 extends or retracts, thereby achieving protection for the transformer body 1.

[0025] Furthermore, there are two swing blocks 26, which are symmetrically arranged about the length of the protective plate 23. By setting the swing blocks 26, the swing blocks 26 can be driven to swing when the second spring 27 extends or retracts.

[0026] Furthermore, two sets of first springs 22 are provided. The first springs 22 are symmetrically arranged with respect to the length centerline of the protective plate 23. By setting the first springs 22, the two sets of first springs 22 can extend and retract simultaneously when subjected to impact, thereby improving the buffering effect and ensuring the stability of the transformer body 1.

[0027] Furthermore, a water supply pipe 32 is fixed to one end of the water pump 31, and a water outlet pipe 34 is fixed to the other end of the water pump 31. Through the setting of the water pump 31, coolant can be drawn from the water tank 33 and delivered to the corrugated radiator through the water supply pipe 32. At the same time, after absorbing heat, the coolant flows back to the water tank 33 through the water outlet pipe 34, forming a cooling cycle.

[0028] Furthermore, a circulating water pipe 35 is fitted onto the outer wall of the transformer body 1, with one end of the circulating water pipe 35 connected to the water tank 33. The circulating water pipe 35 ensures that the coolant, while flowing in the corrugated radiator, fully absorbs the heat generated by the transformer body 1 and returns to the water tank 33 for cooling, thus achieving effective heat dissipation for the transformer body 1.

[0029] Working Principle: During operation, firstly, when the transformer body 1 is impacted by seismic waves, the protective mechanism 2 quickly activates its buffering protection function. The impact first acts on the protective plate 23, and the first spring 22 begins to extend and retract, effectively absorbing part of the impact force. Simultaneously, the swing block 26 swings around the fixed shaft 28, and the second spring 27 extends and retracts accordingly, further dispersing and absorbing the impact energy, preventing the transformer body 1 from shifting due to stress concentration, and ensuring its safety during earthquakes. Secondly, when the operating temperature of the transformer body 1 rises, the cooling mechanism 3 activates to dissipate heat. The water pump 31 operates, drawing coolant from the water tank 33 through the water pipe 32. The coolant flows in the corrugated radiator, efficiently absorbing the heat generated by the transformer body 1. Subsequently, the coolant enters the circulating water pipe 35 through the outlet pipe 34 and finally flows back to the water tank 33 for cooling circulation, ensuring that the transformer body 1 can still operate stably in high-temperature environments.
