Description

Technical Field

[0001] The utility model belongs to the technical field of basic engineering of box-type oil-immersed transformers, and in particular relates to an integrated oil-water separation box-type transformer basic structure. Background Art

[0002] With the growth of my country's new energy demand and the improvement of technology, the construction and operation and maintenance of power systems have also received more attention and importance. As a modern substation equipment, the infrastructure construction of oil-immersed box-type substation has also become a focus, which directly affects the stability and reliability of the power station. The box-type substation foundation is an infrastructure used in actual production of box-type substations. Its main function is to support the box-type substation body, fix the box-type substation, and improve the stability and safety of the box-type substation. According to the substation design specifications, the foundation of the oil-immersed box-type substation should be equipped with an oil storage tank.

[0003] Today's traditional box-type transformer foundations usually have open brick-concrete oil pools around the foundation. However, during the rainy season, a large amount of rainwater will enter these oil pools and quickly fill the entire space. Once the box-type transformer equipment fails, such as transformer oil leakage, since the oil pool is already filled with rainwater, the leaked cooling oil is likely to overflow the oil pool, causing environmental pollution and safety hazards. Therefore, operation and maintenance personnel need to go to each box-type transformer location in time after the rain to perform drainage operations to ensure the normal use of the oil pool.

[0004] However, renewable energy power stations are usually widely distributed, with a large number of box-type transformers and scattered locations, which means that operation and maintenance personnel need to invest a lot of time and manpower in daily drainage work, which not only increases operation and maintenance costs, but also greatly reduces work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated oil-water separation box-type transformer basic structure to solve the problems mentioned in the background technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is an integrated oil-water separation box transformer basic structure, comprising an equipment installation platform, a base, an oil storage tank, a filter, a guide groove and an oil baffle plate, wherein the box transformer equipment is fixed to the upper side of the equipment installation platform by bolts, and the base is fixed to the lower side of one end of the equipment installation platform; an oil storage tank is fixed to one end of the base, wherein the upper end of the oil storage tank is fixed to the lower side of the equipment installation platform, and a filter is fixed inside the end of the equipment installation platform close to the oil storage tank; a guide groove is fixed to the outer side of the oil storage tank, wherein the oil baffle plate is fixed to the upper side of the outer edge of the guide groove.

[0008] Furthermore, the oil storage tank includes a tank body, a first oil tank cabin body, a second oil tank cabin body, a baffle, a connecting hole and a drain hole, wherein a side surface of the lower end of the tank body is fixed to the base, and an upper end of the tank body is fixed to a lower side surface of an equipment mounting platform; a first oil tank cabin body and a second oil tank cabin body are respectively provided inside the tank body, wherein a baffle is provided between the first oil tank cabin body and the second oil tank cabin body, an outer edge of the baffle is fixed to an inner wall of the tank body, and a connecting hole is provided through the lower end of the baffle; a drain hole is provided on a side surface of the upper end of the tank body, and such an arrangement can store accumulated water and automatically drain excess accumulated water when the box-type transformer equipment is operating normally, and when the box-type transformer equipment fails and the transformer leaks oil, since the density of the cooling oil is less than that of water, the cooling oil can be stored inside the first oil tank cabin body and handled by operation and maintenance personnel.

[0009] Furthermore, the base and the oil storage tank are both fixed inside the ground, and the lower end of the guide groove is flush with the ground. Such an arrangement not only reduces the floor space, but also improves the safety of the equipment.

[0010] Furthermore, the upper side of the filter screen is flush with the upper side of the equipment installation platform, and the lower side of the filter screen is in contact with the upper side of the guide groove. Such an arrangement can filter the accumulated water and cooling oil passing through.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] First, when the box-type transformer equipment is operating normally, rainwater in the guide trough flows through the filter net into the first oil pool cabin. The first oil pool cabin and the second oil pool cabin are connected by a connecting hole. When the accumulated water is higher than the drain hole, the accumulated water is discharged from the second oil pool cabin through the drain hole. The operation and maintenance personnel do not need to drain the oil storage tank after rain, thereby reducing the operation and maintenance workload. Secondly, when the box-type transformer equipment fails and the transformer leaks oil, the cooling oil can also flow into the first oil pool cabin through the filter net. Since the density of the cooling oil is less than that of water, it will automatically float above the previous accumulated water. Under the action of the cooling oil's own weight, the accumulated water in the first oil pool cabin is squeezed out, flows into the second oil pool cabin through the connecting hole, and is finally discharged through the drain hole. In this way, the cooling oil is effectively stored in the first oil pool cabin, waiting for the operation and maintenance personnel to handle it. This design not only realizes the automatic separation of oil and water, but also avoids the use of pipelines for oil transportation, thereby eliminating the hidden dangers of pipeline failure, reducing the foundation cost, and improving the stability and reliability of the entire system.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 3As shown, the utility model is an integrated oil-water separation box transformer foundation structure, including an equipment installation platform 1, a base 2, an oil storage tank 3, a filter screen 4, a guide groove 5 and an oil baffle plate 6, the upper side of the equipment installation platform 1 is fixed with a box transformer equipment by bolts, and the base 2 is fixed with the lower side of one end of the equipment installation platform 1; the oil storage tank 3 is fixed at one end of the base 2, wherein the upper end of the oil storage tank 3 is fixed to the lower side of the equipment installation platform 1, and the filter screen 4 is fixed inside the end of the equipment installation platform 1 close to the oil storage tank 3; the guide groove 5 is fixed on the outer side of the oil storage tank 3, wherein the oil baffle plate 6 is fixed on the upper side of the outer edge of the guide groove 5.

[0023] like Figure 4 As shown, the oil storage tank 3 includes a tank body 31, a first oil tank cabin body 32, a second oil tank cabin body 33, a baffle 34, a connecting hole 35 and a drainage hole 36. A side surface of the lower end of the tank body 31 is fixed to the base 2, and the upper end of the tank body 31 is fixed to the lower side surface of the equipment installation platform 1; the first oil tank cabin body 32 and the second oil tank cabin body 33 are respectively provided inside the tank body 31, wherein a baffle 34 is arranged between the first oil tank cabin body 32 and the second oil tank cabin body 33, the outer edge of the baffle 34 is fixed to the inner wall of the tank body 31, and the lower end of the baffle 34 is penetrated by a connecting hole 35; a side surface of the upper end of the tank body 31 is provided with a drainage hole 36, when the box transformer equipment is operating normally, rainwater in the guide groove 5 passes through the filter screen 4 and flows into the first oil tank cabin body 32 and the second oil tank cabin body 33 In the body 32, there is only water in the first oil pool cabin body 32. The first oil pool cabin body 32 and the second oil pool cabin body 33 are connected through the connecting hole 35. When the accumulated water is higher than the drain hole 36, the accumulated water is discharged from the second oil pool cabin body 33 through the drain hole 36, and no manual drainage is required. When the box-type transformer equipment fails and the transformer leaks oil, the cooling oil passes through the filter screen 4 and flows into the first oil pool cabin body 32. Since the density of the cooling oil is less than the density of water, the cooling oil in the first oil pool cabin body 32 floats on the accumulated water before, and then under the action of the self-weight of the cooling oil, the accumulated water in the first oil pool cabin body 32 is discharged into the second oil pool cabin body 33 through the connecting hole 35, and the cooling oil is stored in the first oil pool cabin body 32 and processed by the operation and maintenance personnel.

[0024] Specifically, the base 2 and the oil storage tank 3 are both fixed inside the ground, and the lower end of the guide groove 5 is flush with the ground. This arrangement not only reduces the footprint, but also improves the safety of the equipment and avoids potential damage to the oil storage tank by external factors such as man-made damage or natural disasters.

[0025] Specifically, the upper side of the filter screen 4 is flush with the upper side of the equipment mounting platform 1, and the lower side of the filter screen 4 is in contact with the upper side of the guide groove 5. When in use, the accumulated water and cooling oil inside the guide groove 5 can flow into the first oil pool cabin 32 at the position of the filter screen 4, wherein the filter screen 4 can filter the accumulated water and cooling oil passing through.

[0026] See also Figure 1-4 As shown, the utility model is an integrated oil-water separation box transformer basic structure, and its working principle is: when in use, the box transformer equipment is fixed on the equipment installation platform 1, when the box transformer equipment works normally and it rains, the rainwater sliding down the box transformer equipment will enter the guide groove 5, and then flow along the guide groove 5 to the position of the filter screen 4, and then pass through the filter screen 4 into the first oil pool cabin 32, because the first oil pool cabin 32 and the second oil pool cabin 33 are connected by the connecting hole 35, so the water level line height inside the first oil pool cabin 32 and the second oil pool cabin 33 is the same, and when the accumulated water is higher than the drainage hole 36, the accumulated water flows through the drainage hole 3 6 discharges the second oil pool cabin 33, and no manual drainage is required. When the box-type transformer equipment fails and the transformer leaks oil, the cooling oil will flow into the guide groove 5 along the box-type transformer equipment, and then pass through the filter screen 4 and flow into the first oil pool cabin 32. Since the density of the cooling oil is less than the density of water, and there is accumulated water in the first oil pool cabin 32, the cooling oil in the first oil pool cabin 32 will float on the accumulated water, and then under the action of the cooling oil's own weight, the accumulated water in the first oil pool cabin 32 is discharged to the second oil pool cabin 33 through the connecting hole 35, and the cooling oil is stored in the first oil pool cabin 32 and processed by the operation and maintenance personnel.
