Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly transformer technology, specifically to an environmentally friendly oil-immersed transformer. Background Technology

[0002] Environmentally friendly transformers are those that significantly reduce their environmental impact during design, manufacturing, operation, and recycling. This is primarily achieved through reducing the use of hazardous substances, improving energy efficiency, reducing noise, and using recyclable materials. They employ biodegradable insulating oil (such as vegetable ester oil) or dry-type design (oil-free) to avoid toxic substances such as those found in PCBs. They comply with international energy efficiency standards (such as IEC 60076 and Chinese GB 20052) and use materials such as amorphous alloy cores to reduce no-load losses (60-70% less than traditional silicon steel sheets). Their structural design facilitates disassembly, and they use recyclable metals (such as copper and aluminum) and environmentally friendly insulating materials (such as cellulose insulating paper). Through optimized magnetic circuit design and vibration damping structures, noise levels can be reduced to 45-55 decibels (compared to approximately 60-70 decibels for traditional transformers), making them suitable for residential areas.

[0003] Existing environmentally friendly oil-immersed transformers often have welded or bent corners in their tanks, lacking cushioning structures and being in geometrically protruding positions, making them susceptible to contact with external objects. Furthermore, the tank steel plate thickness is typically 3-6mm (potentially even thinner for smaller transformers), leading to stress concentration at the corners and weak impact resistance. Therefore, during the handling or installation of these transformers, operating conditions, environmental factors, and human error make the tank corners vulnerable to impacts. This can cause the anti-corrosion paint to peel off, accelerating localized corrosion, and in severe cases, even deformation or damage to the tank, leading to oil leaks.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The present invention provides an environmentally friendly oil-immersed transformer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly oil-immersed transformer includes an oil tank and multiple detachable protective mechanisms located at the corners of the oil tank. Each corner of the oil tank has a mounting plate with mounting holes on its surface. Each protective mechanism includes an anti-collision plate, with a second mounting plate inside the anti-collision plate. The bottom of the second mounting plate has a mounting rod that mates with the mounting holes. Connecting blocks are located on both sides of the anti-collision plate, and buffers are rotatably mounted on each connecting block. Abutments are located on both sides of the corners of the oil tank, and the output end of the buffer abuts against the abutments.

[0008] Preferably, each of the mounting rods has a through hole on its surface, and the mounting rod is inserted into the mounting hole, with a pin inside the through hole.

[0009] Preferably, the anti-collision plate is made of steel and is arranged in a "C" shape.

[0010] Preferably, the stop block has a "C" shaped structure, and the output end of the buffer is embedded in the stop block.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions of one or more of the environmentally friendly oil-immersed transformers provided in this utility model embodiment have at least one of the following technical effects:

[0013] This utility model, through the above-mentioned technical solution, provides a protective mechanism at the corners of the oil tank. During handling or installation, the anti-collision plate protects the corners of the oil tank. When impacted, the external object first contacts the outer surface of the anti-collision plate, causing the anti-collision plate to rotate and transfer the impact force to the buffer. The buffer then buffers and weakens the impact force, effectively protecting the corners of the oil tank and preventing them from being bumped during handling or installation. This improves the service life of the transformer and reduces maintenance costs. Attached Figure Description

[0023] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0024] like Figure 1-4 The diagram shown is a structural schematic of an environmentally friendly oil-immersed transformer according to a preferred embodiment of the present invention.

[0025] In this embodiment, the system includes a fuel tank 1 and multiple detachable protective mechanisms 2 located at the corners of the fuel tank 1. At least four protective mechanisms 2 are provided, depending on the number of corners of the fuel tank 1. A mounting plate 3 is welded to each corner of the fuel tank 1. The mounting plate 3 has a circular mounting hole 4 on its surface. Each protective mechanism 2 includes an anti-collision plate 5. An additional mounting plate 6 is provided inside the anti-collision plate 5. A mounting rod 7, which is circular, is provided at the bottom of the mounting plate 6 and mates with the mounting hole 4. When the mounting rod 7 is inserted into the mounting hole 4, it acts as a pivot, allowing the anti-collision plate 5 to rotate along the axis of the mounting hole 4. Connecting blocks 8 are provided on both sides of the anti-collision plate 5, and buffers 9 are rotatably mounted on each connecting block 8. Abutment blocks 10 are welded to both sides of each corner of the fuel tank 1. The abutment blocks 10 on both sides of the corner of the fuel tank 1 are symmetrically arranged. The output end of the buffer 9 mates with the abutment block 10. When subjected to a collision, the external object will first come into contact with the outer side of the anti-collision plate 5, causing the anti-collision plate 5 to rotate and transfer the impact force generated by the collision to the buffer 9. The buffer 9 will buffer and weaken the impact force, thereby effectively protecting the corners of the oil tank 1 and preventing the corners of the oil tank 1 from being bumped during handling or installation. This improves the service life of the transformer, reduces maintenance costs, and after the handling or installation is completed, the protective mechanism 2 can be disassembled by pulling the mounting rod 7 out of the mounting hole 4.

[0026] In this embodiment, each of the mounting rods 7 has a through hole 11 on its surface. The mounting rod 7 is inserted into the mounting hole 4, and a pin 12 is provided in the through hole 11. This structure serves to limit the mounting rod 7, preventing it from automatically dislodging from the mounting hole 4 and preventing the protective mechanism 2 from falling off.

[0027] In this embodiment, the anti-collision plate 5 is made of steel and has a "C" shaped structure. This structure allows the anti-collision plate 5 to cover a larger angle and range of the corners of the fuel tank 1, resulting in better protection.

[0028] In this embodiment, the abutment block 10 has a "C" shaped structure, and the output end of the buffer 9 is embedded in the abutment block 10. The output end of the buffer 9 is snapped into the abutment block 10 and abuts against the abutment block 10. The abutment block provides a support point and limit function for the output end of the buffer 9, so that the output end of the buffer 9 has a force point.

[0029] This utility model discloses an environmentally friendly oil-immersed transformer. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0030] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0031] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
