Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an oil tank mechanism and a transformer. Background Technology

[0002] The 8MW and above high-capacity new energy power generation transformer is designed to be matched with containerized substations. On one hand, because these containerized substations often operate in semi-indoor spaces with poor heat dissipation, the transformer's heat dissipation capacity needs to be improved. On the other hand, since the transformer needs to be installed in a standard-sized container, a compact structure is required. However, existing transformer technologies struggle to balance both good heat dissipation and a compact structure.

[0003] Therefore, there is an urgent need for an oil tank mechanism and transformer to solve the above problems. Utility Model Content

[0016] As an optional solution, the fuel tank mechanism further includes a first reinforcing rib, a second reinforcing rib, and a support assembly. One end of the first reinforcing rib is connected to the gooseneck tube of the gooseneck radiator, and the other end extends along the stacking direction of the multiple heat sinks of the gooseneck radiator and connects to the heat sinks. The second reinforcing rib connects at least two heat sinks of the gooseneck radiator. The support assembly includes a support member, a support member, and a tie rod. The support member is installed at the lower end of the gooseneck radiator and at the end away from the fuel tank body. The support member connects the support member and the side wall of the fuel tank body. The lower end of the tie rod is connected to the support member, and the upper end is connected to the fuel tank body. Wherein:

[0017] The support member is provided with a mounting hole, and the lower end of the pull rod passes through the mounting hole and is connected to a limiting member.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides a fuel tank mechanism, such as Figure 1 As shown, the oil tank mechanism includes an oil tank body 10 and an oil conservator 50. The oil tank body 10 is used to house at least part of the transformer body and oil used to cool the transformer body. The oil conservator 50 is installed above the oil tank body 10. The oil conservator 50 and the oil tank body 10 are connected by a connecting pipe 83. When the oil temperature in the oil tank body 10 rises and expands, the oil enters the oil conservator 50 through the connecting pipe 83, which prevents the oil tank body 10 from bearing excessive pressure or forming a vacuum, and the oil can enter the oil conservator 50 for heat dissipation and cooling.

[0050] like Figure 1 and Figure 2As shown, the tank body 10 includes a housing 11 and a cover 12. The upper end of the housing 11 is open to facilitate the installation of the transformer body and / or other components into the housing 11. The cover 12 is placed over the opening of the housing 11 to achieve a seal for the tank body 10. In this embodiment, the housing 11 is approximately constructed as a cuboid structure. The projection of the housing 11 onto the horizontal plane is a rectangle, the long side of which is the major axis of the tank body 10, and the short side of which is the minor axis of the tank body 10.

[0051] like Figure 1 and Figure 3 As shown, the fuel tank mechanism also includes a bracket 90, which is installed on the top of the fuel tank body 10, and the fuel tank 50 is installed on the bracket 90. The bracket 90 creates a gap between the lower side of the fuel tank 50 and the top of the fuel tank body 10, allowing airflow to pass through. This facilitates heat dissipation for both the fuel tank 50 and the fuel tank body 10, thereby improving the heat dissipation capacity of the fuel tank mechanism itself. Optionally, multiple brackets 90 can be provided between the fuel tank 50 and the fuel tank body 10, spaced apart, to ensure the stability of the support for the fuel tank 50 and to ensure uniform heat dissipation for all parts of the lower side of the fuel tank 50 and all parts of the top of the fuel tank body 10. In this embodiment, as... Figure 3 As shown, the cross-section of the oil tank 50 is smaller than that of the oil tank body 10. Therefore, after the oil tank 50 is installed on the oil tank body 10, there is still a certain space above the oil tank body 10 around the oil tank 50. The connecting pipe 83 is installed in this space. That is, the projection of the connecting pipe 83 on the tank cover 12 is located in the area covered by the tank cover 12, so as not to increase the overall maximum external size of the oil tank mechanism, which is conducive to improving the structural compactness of the oil tank mechanism.

[0052] like Figure 3As shown, a gas relay 84 is installed on the connecting pipe 83. The gas relay 84 is used to monitor the amount of gas generated by the transformer body inside the oil tank body 10 due to a fault and the oil flow rate, and provides an action signal to the protection device, thereby ensuring the safe operation of the transformer. The structure and working principle of the gas relay 84 are existing technologies and will not be described in detail here. In this embodiment, one end of the connecting pipe 83 is connected to the top of the oil tank body 10, and the other end is connected to the bottom of the oil conservator 50. In this embodiment, a pipe is provided at the upper end of the oil conservator 50 to connect to the external atmosphere. The oil tank mechanism also includes a dehumidifier 85, which is installed on the pipe. The dehumidifier 85 is used to absorb moisture in the air to prevent humid air from entering the oil conservator 50 and contaminating the oil. In this embodiment, the gas relay 84 and the dehumidifier 85 are both arranged above the main body of the oil tank 10 and in the space around the oil storage tank 50. That is, the projections of the gas relay 84 and the dehumidifier 85 on the tank cover 12 are both located within the area covered by the tank cover 12, so as not to increase the maximum external dimensions of the oil tank mechanism, which is beneficial to improving the structural compactness of the oil tank mechanism.

[0053] like Figure 3 and Figure 4 As shown, the fuel tank mechanism also includes a connecting pipe valve 60. The first end (i.e., the upper end) of the connecting pipe valve 60 is connected to the inside of the oil reservoir 50, and the second end (i.e., the lower end) of the connecting pipe valve 60 is connected to the inside of the fuel tank body 10. When the temperature of the oil in the fuel tank body 10 rises and its volume expands, the oil in the fuel tank body 10 can not only enter the oil reservoir 50 through the connecting pipe 83, but also enter the oil reservoir 50 through the connecting pipe valve 60. This increases the flow path of the oil between the oil reservoir 50 and the fuel tank body 10. The process of the oil flowing in the connecting pipe valve 60 can dissipate heat, thereby improving the heat dissipation capacity of the entire fuel tank mechanism. In this embodiment, the projection of the connecting pipe valve 60 on the tank cover 12 is located within the area covered by the tank cover 12, thus not causing an increase in the maximum external dimensions of the fuel tank mechanism, which is beneficial to improving the structural compactness of the fuel tank mechanism.

[0054] like Figure 3 and Figure 4 As shown, the upper end of the connecting pipe valve 60 is connected to the upper region of the oil tank 50. Normally, the connection point between the connecting pipe valve 60 and the oil tank 50 is above the oil surface in the oil tank 50, hence the temperature at this location is lower. In other words, by placing the upper end of the connecting pipe valve 60 in the upper region of the oil tank 50, the temperature difference between the two ends of the connecting pipe valve 60 is increased. This facilitates the expansion of the oil in the oil tank body 10 due to heat, allowing it to flow through the connecting pipe valve 60 into the oil tank 50. During this flow, the oil can dissipate heat more effectively, improving the heat dissipation effect of the oil in the oil tank body 10.

[0055] like Figure 4As shown, the connecting pipe valve 60 includes a first pipe 61, a bellows 63, and a second pipe 62. The two ends of the first pipe 61 are connected to the oil reservoir 50 and one end of the bellows 63, respectively. The two ends of the second pipe 62 are connected to the other end of the bellows 63 and the oil tank body 10, respectively. The bellows 63 can deform to a certain extent. By using a bellows 63 for a part of the connecting pipe valve 60, situations where the connecting pipe valve 60 cannot be assembled due to processing errors, assembly errors, or other factors can be avoided. In this embodiment, the bellows 63 can be a metal bellows, which not only allows for adaptive deformation but also has good heat dissipation capabilities. Both the first pipe 61 and the second pipe 62 are made of rigid materials. The rigidity of the first pipe 61 and the second pipe 62 can maintain the shape of the entire connecting pipe valve 60, preventing it from contacting the oil tank body 10 or the oil reservoir 50, thereby ensuring good heat dissipation. Optionally, both the first pipe 61 and the second pipe 62 are made of metal materials, which not only provides good structural strength but also good heat dissipation.

[0056] like Figure 4 As shown, the connecting pipe valve 60 also includes connecting flanges 64. Connecting flanges 64 are provided at the end of the first pipe 61 near the bellows 63, at both ends of the bellows 63, and at the end of the second pipe 62 near the bellows 63. The first pipe 61 and the second pipe 62 are connected to the connecting flanges 64 at both ends of the bellows 63 respectively through their respective connecting flanges 64. The structure is simple and the connection operation is convenient. Furthermore, by providing a sealing element between adjacent connecting flanges 64, the overall sealing performance of the connecting pipe valve 60 can be improved.

[0057] like Figure 1 As shown, the oil tank mechanism also includes a gooseneck radiator 20, which is installed on at least one side wall of the oil tank body 10. The gooseneck radiator 20 is used to dissipate heat from the oil inside the oil tank body 10.

[0058] like Figure 1 and Figure 5As shown, the gooseneck radiator 20 includes a gooseneck tube 21 and multiple parallel and spaced-apart heat sinks 22. The heat sinks 22 are parallel to the side wall of the oil tank body 10 on which the gooseneck radiator 20 is installed. The gooseneck radiator 20 includes two gooseneck tubes 21, located above and below the heat sinks 22 respectively. The upper gooseneck tube 21 is connected to the upper end of the oil tank body 10, and the lower gooseneck tube 21 is connected to the lower end of the oil tank body 10. The upper and lower ends of each heat sink 22 are connected to the upper and lower gooseneck tubes 21 respectively, and the heat sink 22 at the ends is positioned opposite to the side wall of the oil tank body 10. When the oil temperature in the oil tank body 10 rises, the oil enters the gooseneck radiator 20 from the upper gooseneck tube 21. After the oil flows downward through the heat sinks 22 and is sufficiently cooled, it flows back into the oil tank body 10 from the lower gooseneck tube 21, thus achieving a cooling effect.

[0059] like Figure 2 and Figure 5 As shown, a first mating flange 23 is provided at the end of the gooseneck tube 21, and a second mating flange 113 is provided on the side wall of the oil tank body 10. The first mating flange 23 and the second mating flange 113 abut and connect, thereby realizing the connection between the gooseneck radiator 20 and the oil tank body 10. The thickness of the first mating flange 23 and the second mating flange 113 themselves creates a gap 40 between the heat sink fins 22 located at the end and the side wall of the oil tank body 10 (e.g., ...). Figure 8 (As shown). It is understandable that by increasing the oil passage gap in the heat sink 22 of the gooseneck radiator 20, the heat dissipation capacity of the gooseneck radiator 20 can be improved.

[0060] like Figure 1 and Figure 2 As shown, the sidewall parallel to the major axis of the fuel tank body 10 is defined as the first sidewall 111, and the sidewall parallel to the minor axis of the fuel tank body 10 is defined as the second sidewall 112. The fuel tank body 10 has two first sidewalls 111 and two second sidewalls 112. In this embodiment, four gooseneck radiators 20 are provided on each first sidewall 111. In other embodiments, the number of gooseneck radiators 20 on each first sidewall 111 can be flexibly set, or gooseneck radiators 20 can be provided only on one sidewall. In other embodiments, gooseneck radiators 20 can also be provided on the second sidewall 112, which is not limited here.

[0061] like Figure 5As shown, in some embodiments, the fuel tank mechanism further includes a first reinforcing rib 81 and a second reinforcing rib 82. One end of the first reinforcing rib 81 is connected to the gooseneck tube 21 of the gooseneck radiator 20, and the other end extends along the stacking direction of the multiple heat dissipation fins 22 of the gooseneck radiator 20 and is connected to the heat dissipation fins 22. The first reinforcing ribs 81 located on both sides of the gooseneck tube 21 form a V-shaped reinforcing structure. The second reinforcing rib 82 connects at least two heat dissipation fins 22 of the gooseneck radiator 20. By setting the first reinforcing rib 81 and the second reinforcing rib 82, the structural robustness of the gooseneck radiator 20 can be improved, preventing damage during transportation and use. Optionally, both the first reinforcing rib 81 and the second reinforcing rib 82 can be connected to the gooseneck radiator 20 by welding. Optionally, both the first reinforcing rib 81 and the second reinforcing rib 82 can be made of metal materials, thereby not only improving the structural strength of the gooseneck radiator 20, but also improving its heat dissipation capacity.

[0062] like Figure 6 As shown, the fuel tank mechanism also includes a support assembly 70, which includes a support member 71, a support member 72, and a tie rod 73. The support member 71 is installed at the lower end of the gooseneck radiator 20 and at the end away from the fuel tank body 10. The support member 72 connects the support member 71 and the side wall of the fuel tank body 10. The tie rod 73 is inclined, with its lower end connected to the support member 71 and its upper end connected to the fuel tank body 10. Thus, the support member 72, the tie rod 73, and the side wall of the fuel tank body 10 form a triangular support structure, thereby providing reliable support for the gooseneck radiator 20 and preventing it from cracking during transportation. Specifically, as... Figure 8 As shown, the support 71 is connected to the gooseneck tube 21 below the gooseneck radiator 20. Optionally, several gooseneck radiators 20 located on the same side wall of the oil tank body 10 can be connected by the same support 71, so that the gooseneck radiators 20 form mutual limiting and fixing, further preventing the gooseneck radiators 20 from loosening during transportation. Optionally, the support 71 can be an angle steel.

[0063] In some embodiments, such as Figure 6 and Figure 7 As shown, the support member 71 is provided with a mounting hole 711, and the lower end of the pull rod 73 passes through the mounting hole 711 and is connected to the limiting member 75. Optionally, the limiting member 75 can be a nut, which is threadedly connected to the lower end of the pull rod 73. In other embodiments, the limiting member 75 can also be a pin, which passes through the lower end of the pull rod 73 to prevent the lower end of the pull rod 73 from coming out of the mounting hole 711 from bottom to top. In this embodiment, as Figure 7As shown, the cross-sectional area of ​​the mounting hole 711 is larger than that of the pull rod 73, so that the position of the upper end of the pull rod 73 is adjustable. During actual installation of the pull rod 73, if the installation of the mating structure on the fuel tank body 10 (such as the hook 74 or snap fastener described below) used to mate with the pull rod 73 has errors, the upper end of the pull rod 73 may not be able to be installed correctly. By setting the cross-sectional area of ​​the mounting hole 711 to be larger than that of the pull rod 73, the lower end of the pull rod 73 can be connected to the limiter 75 and then swing for adjustment, thereby allowing the position of the upper end of the pull rod 73 to be adjusted and thus successfully mating with the aforementioned mating structure.

[0064] In some embodiments, such as Figure 6 As shown, a hook 74 is welded to the side wall of the fuel tank body 10, and the upper end of the pull rod 73 is sleeved on the hook 74, thereby achieving a connection with the fuel tank body 10. The connection is reliable and the operation is convenient. In some embodiments (not shown), a fastener is fixed to the side wall of the fuel tank body 10, and the upper end of the pull rod 73 is held by the fastener. It is understood that the fastener can be any existing structure capable of holding the rod, and is not limited here.

[0065] like Figure 6 As shown, the fuel tank mechanism also includes a column 76. The upper end of the column 76 is connected to the support assembly 70, and the lower end of the column 76 is used for support on the ground. During transportation of the fuel tank mechanism, the column 76 may not be installed. After the fuel tank mechanism is transported and placed in its intended location, the column 76 can support the support assembly 70, thereby improving the support and reinforcement of the gooseneck radiator 20 and enhancing the overall stability of the fuel tank mechanism. Optionally, the upper end of the column 76 can be connected to either the support member 71 or the support member 72; this is not limited here. Optionally, the column 76 can be an existing horizontal support leg; its specific structure and usage will not be described in detail.

[0066] like Figure 2 and Figure 8As shown, the tank mechanism also includes a corrugated radiator 30, which is connected to the side wall of the tank body 10. At least one corrugated radiator 30 is located within the gap 40 formed between the gooseneck radiator 20 and the side wall of the tank body 10. The corrugated radiator 30 can increase the heat dissipation effect on the surface of the tank body 10. In this embodiment, the tank mechanism is equipped with both a gooseneck radiator 20 and a corrugated radiator 30, resulting in good heat dissipation. Furthermore, since the corrugated radiator 30 is located within the gap 40 naturally formed when the gooseneck radiator 20 is connected to the tank body 10, it does not increase the maximum external dimensions of the tank mechanism. Therefore, this embodiment's tank mechanism, while maintaining a compact overall structure, has strong heat dissipation capacity, thus meeting the requirements for use in containerized substations. Optionally, the corrugated radiator 30 can be connected to the tank body 10 by welding. Optionally, in some embodiments, the corrugated radiator 30 can be a solid corrugated fin, which is simple in structure and easy to install. In some embodiments, the corrugated radiator 30 is a corrugated fin with an internal channel that communicates with the tank body 10, thereby further improving the heat dissipation capacity of the tank mechanism.

[0067] like Figure 1 , Figure 2 and Figure 8 As shown, in this embodiment, a corrugated radiator 30 is provided between each gooseneck radiator 20 and the oil tank body 10. That is, multiple corrugated radiators 30 are provided on the first side wall 111 of the oil tank body 10. In other embodiments, corrugated radiators 30 may be provided only in the interval 40 between some of the gooseneck radiators 20 and the oil tank body 10, which is not limited here.

[0068] like Figure 2 and Figure 8 As shown, a corrugated radiator 30 is also provided on the second side wall 112, which can further improve the surface heat dissipation effect of the fuel tank body 10 and improve the overall heat dissipation capacity of the fuel tank mechanism. It should be noted that the second side wall 112 of the fuel tank body 10 has a protruding port for connecting to an external power source. As long as the height of the corrugated radiator 30 does not exceed the height of the port, it will not lead to an increase in the maximum external dimensions of the fuel tank mechanism, thus ensuring the compactness of the structure.

[0069] like Figure 2As shown, longitudinal reinforcing ribs 13 and transverse reinforcing ribs 14 are provided on the sidewalls of the fuel tank body 10. The longitudinal and transverse reinforcing ribs 13 and 14 improve the structural strength of the fuel tank body 10 and prevent deformation due to excessive external connections. In this embodiment, multiple longitudinal reinforcing ribs 13 are provided on the first sidewall 111, spaced laterally, and transverse reinforcing ribs 13 are provided on adjacent longitudinal reinforcing ribs 14. Corrugated radiators 30 are disposed within the area enclosed by the longitudinal and transverse reinforcing ribs 13 and 14.
