Description

Technical Field

[0001] This application relates to the field of civil engineering technology, and in particular to a suspended transformer emergency oil collection tank device. Background Technology

[0002] Transformer oil sumps are critical facilities used to collect waste oil discharged during transformer accidents, preventing environmental pollution and the spread of fire. When an internal transformer fault occurs (such as a short circuit, arcing, or overload), high-temperature insulating oil may leak or splash. The oil sump quickly collects the leaked oil, preventing it from flowing and contacting other flammable materials or high-temperature components, thus avoiding the spread of fire. Conventional transformer oil sumps are located on the ground and are typically constructed of concrete or brick.

[0003] However, in some special locations, such as steep slopes, with the rapid construction of substations in mountainous areas, especially photovoltaic power stations and wind power stations, the number of supporting facilities such as transformers has gradually increased. Many small transformers need to be installed on steep slopes due to terrain limitations, and conventional emergency oil collection devices cannot be installed, or the required engineering work is too large.

[0004] A transformer accident oil collection device that is easy to install and has a low overall cost is needed, based on the actual situation, to meet the fire safety requirements when a transformer accident occurs, and to be compatible with the terrain of steep slopes in mountainous areas and transformers installed overhead. Utility Model Content

[0005] To solve or partially solve the problems existing in the related technologies, this application provides a suspended transformer accident oil collection tank device, which suspends the transformer and uses an overhead oil collection platform and a suspended oil collection tank to collect the insulating oil leaked during an accident.

[0006] This application provides a suspended transformer emergency oil collection tank device, including: a support platform, an oil collection platform and a suspended oil collection tank. The support platform is used to suspend the transformer and the suspended oil collection tank is fixedly connected to the bottom. The oil collection platform extends outward along the support platform. The bottom plate of the oil collection platform is an inclined closed flat plate and the side closest to the support platform is the lowest point. The lowest point is connected to the suspended oil collection tank through an oil collection pipe.

[0007] The oil collection platform is equipped with an oil baffle and railings along its outer perimeter, and an oil baffle plate is installed inside the railings.

[0008] The top of the suspended oil collection tank is suspended and fixed to the lower part of the crossbeam of the support platform using steel profiles and bolts. It includes a first chamber located directly below the transformer and a second chamber connected to the oil collection pipeline. The first chamber and the second chamber are set up independently.

[0009] The suspended oil collection tank is equipped with an oil drain pipe and a drainage pipe controlled by valves.

[0010] The oil drain pipe is located at the top of the suspended oil collection tank, close to the oil layer area, while the drain pipe is located at the bottom of the suspended oil collection tank.

[0011] The technical solution provided in this application may include the following beneficial effects: This application provides a suspended transformer emergency oil collection tank device. Designed for steep slopes and other challenging terrain, it eliminates the need for concrete or brick oil collection pits. By combining an overhead oil collection platform with a suspended oil collection tank, it solves the problems of conventional ground-based oil collection pits being impractical or requiring excessive construction in special terrains. This expands the applicability of outdoor box-type transformers and enhances site adaptability. The device can quickly collect leaked or splashed high-temperature insulating oil during transformer faults, preventing oil from flowing and contacting flammable materials or high-temperature components, thus preventing the spread of fire at its source. This significantly improves the fire and explosion safety of outdoor overhead transformers, ensuring the safety of the surrounding environment and equipment.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 The suspended transformer 3 emergency oil collection tank device shown includes: a support platform 2, an oil collection platform 1, and a suspended oil collection tank 7. For example... Figure 3 As shown, the support platform 2 is used to support the transformer 3 overhead. In order to ensure ventilation and heat dissipation, maintain the stable operation of the transformer 3, and avoid heat accumulation due to the bottom being sealed, thereby preventing the transformer 3 from overheating and causing a fault, the support platform 2 adopts a hollow structure.

[0022] A suspended oil collection tank 7 is fixedly connected to the bottom of the support platform 2. The top of the suspended oil collection tank 7 is suspended and fixed to the lower part of the crossbeam of the support platform 2 using steel profiles and bolts. It includes a first chamber located directly below the transformer 3 and a second chamber connected to the oil collection pipe 6, and the first chamber and the second chamber are set independently. The tank structure is made of non-combustible materials, and the tank volume is sufficient to accommodate the oil leakage in the event of an accident involving the transformer 3.

[0023] Because the bottom of transformer 3 has several leak-prone areas such as the oil drain valve, oil pipe interface, and shell welds, insulating oil can easily leak downwards from these locations when the seals age or fail. The hollow area at the bottom of support platform 2 serves as an oil leakage channel, and the first chamber, which is set at the top opening directly below, acts as an oil receiving device to directly collect the dripping insulating oil.

[0024] The oil collection platform 1 extends outward from the supporting platform 2. The base of the oil collection platform 1 is an inclined, closed flat plate, with the lowest point near the supporting platform 2, gradually increasing in height outward to form an oil-guiding slope. At the lowest point, it connects to the suspended oil collection tank 7 via an oil collection pipe 6, and a filter screen is installed at the oil inlet of the oil collection pipe 6. An oil baffle 4 and a railing 5 are installed along the perimeter of the outer side of the oil collection platform 1, with an oil baffle plate 10 installed inside the railing 5. The oil baffle 4 prevents oil from flowing outward from the platform, primarily addressing oil spills that spread along the platform after a bottom leak. The oil baffle plate 10, made of a sealed material, is installed inside the railing, tightly against the oil baffle 4, forming a continuous, seamless interception barrier that directly blocks oil droplets splashing from the sides and at an angle, preventing them from overflowing over the railing 5. The height of the oil baffle plate 10 can be designed to adapt to different oil droplet spray heights under various fault scenarios, providing dual protection against flow from the oil baffle 4 and against splashing from the oil baffle plate 10. The oil baffle 10 and the oil baffle 4 work together to guide the splashed oil droplets into the oil collection platform 1.

[0025] Since the first chamber collects pure insulating oil leaking directly from the bottom of transformer 3, without the ingress of rainwater or other impurities, it can be recycled or disposed of in compliance with regulations without complex separation treatment, avoiding resource waste caused by the mixing of pure oil and sewage. The second chamber collects an oil-water mixture that may contain rainwater, requiring targeted oil-water separation treatment. Each of the two chambers of the suspended oil collection tank 7 is equipped with a valve-controlled drain pipe 8, and the second chamber also has a drain pipe 9. The drain pipe 8 is located at the top of the suspended oil collection tank 7, close to the oil layer area, ensuring accurate drainage of pure oil and preventing the mixing of bottom water. The drain pipe 9 is located at the bottom of the suspended oil collection tank 7, ensuring thorough drainage of accumulated rainwater and preventing long-term water retention from affecting the tank or oil quality.

[0026] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
