Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a corrugated transformer oil tank. Background Art

[0002] Corrugated transformer oil tanks are widely used in power systems. Their main function is to store transformer oil and allow a certain degree of volume change to accommodate the expansion or contraction of the oil volume caused by temperature changes.

[0003] Most of the corrugated transformer tanks on the market currently rely on a single-layer corrugated design. Although this design simplifies the manufacturing process to a certain extent, it has many shortcomings in practical applications. First, the single-layer corrugation cannot effectively disperse stress. Especially under extreme working conditions, the corrugation is prone to permanent deformation, which reduces the overall performance of the tank. Secondly, the single-layer corrugated structure performs poorly in adapting to a wide range of temperature changes and cannot meet the growing demand for tank performance in modern power systems. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] The present invention is proposed in view of the fact that the above-mentioned single-layer corrugation cannot effectively disperse stress, and in particular, the corrugation is prone to permanent deformation under extreme working conditions, thereby reducing the overall performance of the oil tank.

[0006] Therefore, an object of the present invention is to provide a corrugated transformer oil tank.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a corrugated transformer oil tank, comprising: a main body assembly, including an oil tank body, a sleeve member arranged at the top of the oil tank body for connecting a line, the sleeve member is evenly arranged along the length direction of the oil tank body, and a bottom plate member for driving the overall movement of the transformer is installed at the bottom end of the oil tank body; and

[0008] The heat dissipation assembly includes a heat dissipation member arranged on the side wall of the oil tank body. The heat dissipation member is located around the oil tank body and is evenly distributed for heat dissipation of the oil tank body. An expansion member is arranged inside the heat dissipation member to reserve expansion space for oil expansion.

[0009] As a preferred solution of the corrugated transformer oil tank of the present invention, the side wall of the bushing is equipped with a lifting and hanging stirrer, and the lifting and hanging stirrer is symmetrically arranged with respect to the central axis of the oil tank body.

[0011] As a preferred solution of the corrugated transformer oil tank of the present invention, the heat sink is made of high-efficiency heat dissipation material.

[0012] As a preferred solution of the corrugated transformer oil tank of the present invention, the design of the expansion member can adapt to the volume change of the oil body under different temperature conditions, and has a corrugated shape to enhance the expansion efficiency.

[0013] As a preferred solution of the corrugated transformer oil tank of the present invention, the bushing member includes a high-voltage bushing arranged at the top of the oil tank body, a low-voltage bushing is arranged on the side wall of the high-voltage bushing, and the bottom end of the low-voltage bushing is connected to the oil tank body.

[0014] As a preferred solution of the corrugated transformer oil tank of the present invention, the bushing member further comprises a gas relay arranged at the top of the oil tank body, and a tubular oil level gauge is installed on the side of the low-voltage bushing away from the gas relay.

[0015] As a preferred solution of the corrugated transformer oil tank of the present invention, the bottom plate member includes a bottom angle arranged at the bottom end of the oil tank body, the bottom angle is arranged in an inverted "U" shape, and a moving wheel is installed at the bottom end of the bottom angle.

[0016] As a preferred solution of the corrugated transformer oil tank of the present invention, the heat sink includes a shell arranged on the side wall of the oil tank body, a fixing groove is arranged inside the shell, and the top and bottom ends of the shell gradually narrow to form a limiting groove.

[0017] As a preferred solution of the corrugated transformer oil tank of the present invention, the expansion member includes an expansion plate arranged inside the fixing groove, the expansion plate is arranged in a corrugated shape and connected to and communicated with the oil tank body, the top and bottom ends of the expansion plate are slowly narrowed in opposite directions and are equipped with a sliding block, and the sliding block is located inside the limiting groove;

[0018] A buffer plate is installed on the side wall of the expansion plate. The buffer plate is located inside the fixing groove, and the buffer plate has three surface contacts with the expansion plate through spring washers, so as to improve the expansion stability of the expansion plate.

[0019] Beneficial effects of the present invention: By adding a design of a corrugated expansion plate and equipping it with a sliding block and a buffer plate, the present invention can effectively disperse stress and reduce the risk of permanent deformation of the corrugation when the volume of the oil body changes due to temperature changes, thereby improving the deformation resistance of the oil tank. The multi-point contact design of the spring gasket and the expansion plate improves the stability of the expansion plate during the expansion and contraction process, prevents mechanical stress damage caused by sudden changes in oil temperature, and makes the expansion plate work more reliable. By optimizing the design of the expansion piece, the present invention not only solves the problem of easy deformation of the single-layer corrugation, but also improves the overall durability of the oil tank, extends the service life of the equipment, and reduces the cost of maintenance and replacement. The heat sink is evenly distributed around the oil tank body, and the fixed groove and limit groove design inside the shell ensure the effective operation of the heat sink, improve the heat dissipation efficiency, and help maintain the temperature of the transformer within a safe range during operation. Through an effective stress dispersion mechanism and a stable expansion plate design, the present invention can maintain the integrity of the oil tank under extreme working conditions, avoid potential safety problems caused by internal pressure fluctuations, and improve the safety of equipment operation.

[0020] In summary, the present invention significantly improves the shortcomings of traditional single-layer corrugated oil tanks by introducing a multi-layer corrugated design and an enhanced buffer mechanism, which not only improves the durability and stability of the oil tank, but also optimizes the heat dissipation effect and simplifies maintenance work, thereby improving the performance and safety of the corrugated transformer oil tank as a whole.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0040] Example 1, reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides a corrugated transformer oil tank, including an oil tank body 101 as a sealed container, which not only stores transformer oil, but also isolates the external environment to prevent the oil from being contaminated.

[0041] Specifically, the main assembly 100 includes an oil tank body 101, a sleeve member 102 arranged at the top of the oil tank body 101 for connecting the line, the sleeve member 102 is evenly arranged along the length direction of the oil tank body 101, and a bottom plate member 103 for driving the overall movement of the transformer is installed at the bottom of the oil tank body 101. The main function of the corrugated transformer oil tank is to contain transformer oil and protect the internal electrical components. The oil tank body 101 is a sealed container for storing transformer oil and preventing the external environment from affecting the oil quality. As the main oil storage container, the oil tank body 101 not only provides a closed space for storing transformer oil, but also its corrugated design can adapt to the volume change of the oil body due to temperature changes and reduce internal pressure fluctuations.

[0042] Furthermore, a lifting and mixing device 104 is installed on the side wall of the bushing member 102. The lifting and mixing device 104 is symmetrically arranged with respect to the central axis of the oil tank body 101. The lifting and mixing device 104 ensures that the transformer can be safely and smoothly installed or moved.

[0043] Furthermore, the bushing 102 includes a high-voltage bushing 102a disposed at the top of the oil tank body 101, which is used to connect the high-voltage circuit part of the transformer to ensure that the current is input into the transformer from the external power supply. The side wall of the high-voltage bushing 102a is provided with a low-voltage bushing 102b, which is connected to the low-voltage output part of the transformer so that the current can be transmitted to the load. The bottom end of the low-voltage bushing 102b is connected to the oil tank body 101. The high-voltage bushing 102a and the low-voltage bushing 102b are respectively used to connect the high-voltage and low-voltage parts of the transformer. The gas relay 102c detects the gas content in the transformer oil and promptly discovers possible faults. The tubular oil level gauge 102d displays the changes in the oil level to help operators monitor the oil volume and ensure that the oil volume is within a safe range.

[0044] Furthermore, the bushing 102 further includes a gas relay 102c disposed at the top of the oil tank body 101, and a tubular oil level gauge 102d is installed on a side of the low-pressure bushing 102b away from the gas relay 102c.

[0045] Furthermore, the bottom plate member 103 includes a bottom corner 103a arranged at the bottom end of the tank body 101, the bottom corner 103a is arranged in an inverted "U" shape, and a moving wheel 103b is installed at the bottom end of the bottom corner 103a. The bottom plate member 103 provides mobility, and the bottom corner 103a and the moving wheel 103b enable the entire device to be moved between different positions.

[0046] Operation process: Before installation, ensure that all components are intact and prepare the necessary tools and equipment. Install the bottom plate 103 at the bottom end of the tank body 101, and ensure that the bottom corner 103a and the moving wheel 103b are firmly installed. Install the high-pressure bushing 102a at the top of the tank body 101, and install the low-pressure bushing 102b on the side wall of the high-pressure bushing 102a, ensuring that both are tightly connected to the tank body 101. Install the gas relay 102c and the tubular oil level gauge 102d, and arrange them reasonably with the high-pressure bushing 102a and the low-pressure bushing 102b. Install the lifting and mixing 104 on the side wall of the bushing 102, and ensure that it is symmetrically arranged to facilitate subsequent lifting operations. Before use, check whether all components are installed correctly, especially whether the gas relay 102c and the tubular oil level gauge 102d are working properly. According to the indication of the tubular oil level gauge 102d, ensure that the oil level is within the appropriate range. Use a crane or other suitable equipment to smoothly lift the corrugated transformer tank and move it to the designated location by hoisting 104. Connect the high-voltage bushing 102a and low-voltage bushing 102b to the power system to ensure that the electrical connections are correct. Regularly check the oil level and the status of the gas relay 102c to ensure that the equipment is operating normally. If the equipment needs to be moved, use the moving wheels 103b to easily move it to the desired location.

[0047] Example 2, reference Figure 1 and Figure 3~Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the heat dissipation component 200 is used to improve the heat dissipation effect of the transformer oil tank and solve the problem of volume change of the oil body caused by temperature change.

[0048] Specifically, the heat dissipation assembly 200 includes a heat dissipation member 201 arranged on the side wall of the oil tank body 101. The heat dissipation member 201 is located around the oil tank body 101, and the heat dissipation member 201 is evenly distributed for heat dissipation of the oil tank body 101. An expansion member 202 is arranged inside the heat dissipation member 201. The expansion member 202 is used to reserve expansion space for oil expansion. The heat dissipation member 201 is designed around the oil tank body 101, and uses natural air convection or forced air cooling to take away the heat generated during the operation of the transformer. The expansion member 202 provides additional space required for the oil body to change in volume due to temperature changes, thereby avoiding safety problems caused by excessive or insufficient internal pressure.

[0049] Furthermore, the heat sink 201 includes a shell 201a arranged on the side wall of the oil tank body 101, and a fixing groove 201b is arranged inside the shell 201a. The top and bottom ends of the shell 201a slowly narrow to form a limiting groove 201c. The top and bottom ends of the shell 201a are designed to gradually narrow to form a limiting groove 201c, which is used to limit the movement range of the expansion member 202 and ensure that the expansion member 202 can freely expand and contract within a certain range.

[0050] The rest of the structure is the same as that of Example 1.

[0051] Operation process: Make sure that all components have been correctly installed in accordance with the requirements of Example 1. Prepare the tools and materials required to install the heat dissipation components. Distribute the heat sink 201 evenly around the oil tank body 101 and ensure that it is firmly installed. Check whether the heat sink 201 is damaged or deformed, and replace it with a new one if necessary. Place the expansion member 202 in the fixing groove 201b inside the heat sink 201. Confirm that the expansion member 202 can move freely in the limit groove 201c, but will not deviate from the fixed range. Check the ventilation effect of the heat sink 201 to ensure that it can dissipate heat effectively. Observe the working status of the expansion member 202 to ensure that it can freely expand and contract with the change of oil temperature without jamming. Start the transformer and observe the temperature change of the oil tank body 101. Monitor whether the gas relay 102c is working properly to ensure that the gas relay 102c can accurately reflect the gas content in the oil. Use the tubular oil level gauge 102d to check whether the oil level is within the normal range and adjust it with the temperature change. Regularly check whether the heat sink 201 is blocked or damaged, and clean the dust or debris on the surface of the heat sink. Regularly check the expansion of the expansion member 202 to ensure that it can work normally. Adjust the cooling method according to the actual situation, such as turning on the forced air cooling system in a high temperature environment.

[0052] Through the above operation process, it can be ensured that the corrugated transformer oil tank can maintain good heat dissipation performance under different working conditions, and when the oil body changes in volume due to temperature changes, the expansion member 202 can effectively absorb this part of the change to prevent abnormal pressure inside the oil tank. This not only improves the reliability of the equipment, but also extends the service life of the transformer.

[0053] Example 3, reference Figure 3~Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that: Embodiment 3 further optimizes the design of the expansion member 202 on the basis of Embodiment 2, aiming to improve the stability and reliability of the expansion member 202.

[0054] Specifically, the expansion member 202 includes an expansion plate 202a disposed inside the fixed groove 201b, the expansion plate 202a is arranged in a corrugated shape and connected to and communicated with the oil tank body 101, the top and bottom ends of the expansion plate 202a are slowly narrowed in opposite directions and are equipped with a sliding block 202b, the sliding block 202b is located inside the limiting groove 201c, the corrugated expansion plate 202a can be stretched or contracted according to the change of oil temperature, and the sliding block 202b ensures the expansion plate 202a to move smoothly in the limiting groove 201c;

[0055] Furthermore, a buffer plate 202d is installed on the side wall of the expansion plate 202a. The buffer plate 202d is located inside the fixing groove 201b, and the buffer plate 202d has three surface contacts with the expansion plate 202a through the spring gasket 202e, which is used to improve the expansion stability of the expansion plate 202a. The buffer plate 202d and the spring gasket 202e are used in combination to enhance the stability of the expansion plate 202a and prevent mechanical stress damage caused by sudden changes in oil temperature.

[0056] The rest of the structure is the same as that of Example 2.

[0057] Operation process: Confirm that all components of Example 2 have been correctly installed and are in good condition. Prepare the tools and materials required for installing and debugging the expansion member. Place the corrugated expansion plate 202a into the fixed groove 201b of the heat sink 201. Make sure that the sliding block 202b of the expansion plate 202a is located in the limiting groove 201c of the heat sink 201 housing 201a and can slide freely. Install the buffer plate 202d in the fixed groove 201b and make it contact with the expansion plate 202a through the spring gasket 202e. Check whether the contact between the buffer plate 202d and the expansion plate 202a is good to ensure that the buffer plate can play a stabilizing role when the expansion plate is retracted. After the installation is completed, carefully check whether all components of the expansion member 202 are installed correctly to ensure that the positions of the sliding block 202b and the buffer plate 202d are accurate. Test the telescopic performance of the expansion plate 202a to ensure that it can move smoothly in the limiting groove 201c without any jamming or looseness. Start the transformer and observe the changes in the oil temperature and oil level in the oil tank body 101 .

[0058] Through the above operation process, Example 3 not only improves the reliability of the expansion member 202, but also enhances its adaptability in complex environments, ensuring that the corrugated transformer oil tank can operate safely and stably under various working conditions.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
