Description

Technical Field

[0001] This application relates to the field of offshore wind power technology, and in particular to a line-out structure, electrical equipment, and wind power device. Background Technology

[0002] With the continuous advancement of wind power technology and the ongoing reduction in costs, wind energy is becoming a major force in the context of a low-carbon economy. Among them, offshore wind power, as one of the main pathways to achieve carbon neutrality, is poised for rapid development. Offshore wind power has advantages such as not occupying land resources, proximity to power loads, high utilization hours, relatively stable wind resources, and high power generation. However, due to the constraints of special geographical environmental factors, offshore wind power stations have high technical requirements for electrical equipment, with strict requirements on product performance, weight, and size.

[0003] Connecting offshore wind farms to the onshore power grid requires high-strength transmission lines. These lines have ground capacitance, which is particularly large for lines laid on the seabed. This increases the capacitive reactive current flowing through the series inductance of the lines, causing a rise in the voltage at the unloaded end of the line, resulting in a capacitive effect. To provide safe and high-quality power, shunt reactors are typically used to reduce the ground capacitance of the transmission lines and suppress the rise in power frequency voltage.

[0004] For three-phase integrated shunt reactors used in offshore wind power, the unique environment of offshore platforms, such as the continuous loads exerted by wind and waves, necessitates transformers for offshore wind power that not only require high voltage levels and large capacities but also excellent insulation performance and mechanical strength. Traditional shunt reactors typically employ integrally molded insulation components and through-shielding structures, resulting in a large and heavy output structure. Given the impact of external factors like wind and waves on offshore wind power platforms, the large and heavy output structure of these shunt reactors is inconvenient to install, significantly increasing installation costs. Summary of the Invention

[0005] Therefore, it is necessary to provide a line structure, electrical equipment, and wind power device to address the problem that the traditional shunt reactor line structure is not convenient for installation on offshore wind power platforms.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] See Figure 1 and Figure 2 The outgoing structure provided in one embodiment of this application includes an outgoing wire 10, a connecting component 20, and a cable terminal 30.

[0039] The conductor located outside the electrical equipment and used to connect the various leads of the internal windings of the electrical equipment is called the lead wire 10 or lead wire, used to output electrical energy from the electrical equipment to the outside. The electrical equipment can be a transformer, reactor, or other equipment used to output electrical energy. The cable terminal 30 is a device installed at the beginning and end of the cable line to complete the connection with other electrical equipment. There are outdoor terminal heads, indoor terminal heads, elbow terminal heads, etc. The cable terminal 30 integrates waterproofing, stress control, shielding, and insulation, and has good electrical and mechanical properties, and can be used for a long time under various harsh environmental conditions.

[0040] One end of the connecting component 20 in the longitudinal direction is connected to the lead wire 10, and the other end in the longitudinal direction is connected to the cable terminal 30, so that the lead wire 10 and the cable terminal 30 are electrically connected to each other through the connecting component 20, so that the electrical energy output by the electrical equipment can be led out to the outside of the electrical equipment through the lead wire 10, and transmitted to the cable terminal 30 through the connecting component 20, and finally transmitted to other electrical equipment, such as electrical appliances, through the cable terminal 30.

[0041] The connecting component 20 includes multiple sequentially connected connectors 21 along its longitudinal direction. Adjacent connectors 21 are detachably connected. In other words, the connecting component 20 can be disassembled into multiple connectors 21 to facilitate segmented transportation of the connecting component 20 and reduce transportation costs.

[0042] Furthermore, if the connecting component 20 cannot be disassembled, when the aforementioned outgoing line structure is applied to an offshore wind power platform, after one end of the connecting component 20 is connected to the lead-out line 10, the other end is affected by the load of sea waves, causing a certain positional deviation in the cable terminal 30 or the lead-out line 10. This can easily lead to a situation where the connecting component 20 cannot be connected to the cable terminal 30. However, by disassembling the connecting component 20 into multiple connecting pieces 21, the lead-out line 10 and the cable terminal 30 can be connected to the connecting pieces 21 at both ends of the connecting component 20 first, and then the remaining connecting pieces 21 can be gradually assembled together. Finally, the assembled connecting component 20 can adapt to the positions of the lead-out line 10 and the cable terminal 30 to meet the installation requirements of the offshore wind power platform.

[0043] The aforementioned outgoing line structure connects the lead-out line 10 and the cable terminal 30 via a connecting component 20, allowing the electrical energy output from the electrical equipment to be transmitted through the connecting component 20 to the cable terminal 30, and finally to other electrical equipment via the cable terminal 30. The connecting component 20 includes multiple sequentially connected connectors 21 along its longitudinal direction. Adjacent connectors 21 are detachable. By disassembling the connecting component 20 into multiple connectors 21, the lead-out line 10 and the cable terminal 30 can be connected to the connectors 21 at both ends of the connecting component 20 first. Then, the remaining connectors 21 can be gradually assembled, ultimately allowing the assembled connecting component 20 to adapt to the positions of the lead-out line 10 and the cable terminal 30 to meet the installation requirements of offshore wind power platforms.

[0044] In the embodiments of this application, since the ends of the lead wire 10 and the cable terminal 30 are usually not on the same horizontal plane in actual applications, the connecting component 20 is configured to extend in a zigzag manner to adapt to the positions of the lead wire 10 and the cable terminal 30. Furthermore, since the connecting component 20 can be disassembled into multiple connectors 21, even with its zigzag extension, it can be disassembled into multiple connectors 21 for ease of transportation and installation.

[0045] In some embodiments, among two adjacent connectors 21, one connector 21 includes a connecting portion 22 and a corner portion 23 that are connected to each other, the connecting portion 22 extending longitudinally along a first direction X. The other connector 21 extends longitudinally away from the connecting portion 22 along a second direction Y that intersects with the first direction X, and is detachably connected to the corner portion 23, so that the two connecting portions 22 and connectors 21 extending longitudinally in different directions can be connected to each other through the corner portion 23.

[0046] In one specific embodiment, the connecting component 20 includes two connectors 21, namely a first connector 24 and a second connector 25. The first connector 24 extends longitudinally along a first direction X and includes a connecting portion 22 and a corner portion 23 that are connected to each other. One end of the connecting portion 22 is connected to the lead wire 10, and the other end is connected to one end of the corner portion 23. The other end of the corner portion 23 is connected to one end of the second connector 25, and the other end of the second connector 25 is connected to the cable terminal 30.

[0047] The connecting portion 22 extends longitudinally along the first direction X, the second connecting member 25 extends longitudinally along the second direction Y, and the corner portion 23 is bent at 90° so that the corner portion 23 can connect to the connecting portion 22 and the second connecting member 25 respectively. In this way, the connecting assembly 20 is L-shaped as a whole through the first connecting member 24 and the second connecting member 25, which has a simple structure and is easy to install.

[0048] Optionally, each of the connectors 21 is a copper rod. In other embodiments, the connector 21 may also be a conductive component such as a cable or a copper pipe. Compared with a cable or copper pipe, the connector 21 is a copper rod, which has a simpler structure, is easier to install, and is easier to insulate.

[0049] In the embodiments of this application, in order to insulate the connecting assembly 20, the outgoing structure further includes a housing 40, which has an insulating cavity 41 for containing insulating oil. One end of the lead wire 10 connected to the connecting assembly 20 is located inside the insulating cavity 41, and the other end of the cable terminal 30 connected to the connecting assembly 20 is also located inside the insulating cavity 41. Thus, when the connecting assembly 20 connects the lead wire 10 and the connecting assembly 20, the entire connecting assembly 20 is located inside the insulating cavity 41. When the insulating cavity 41 is filled with insulating oil, the entire connecting assembly 20 is immersed in the insulating oil, thereby insulating the connecting assembly 20 through the insulating oil.

[0050] In some embodiments, if the connecting component 20 is connected to the cable terminal 30 and no additional fixing is performed, the connecting component 20 is subject to the load of sea waves on the offshore wind power platform for a long time, which may easily cause the connecting component 20 to detach from the lead wire 10 or the cable terminal 30, resulting in the inability to transmit power normally.

[0051] Therefore, the outgoing cable structure also includes a fixing component 50. The connecting component 20 is fixedly installed on the inner wall of the insulating cavity 41 via the fixing component 50, so as to provide additional fixation for the connecting component 20. Since the fixing component 50 and the connecting component 20 are in direct contact, electrical energy on the connecting component 20 can be transferred to the housing 40 through the fixing component 50, creating a safety hazard. Therefore, the outgoing cable structure also includes an insulating component 60, which is disposed between the fixing component 50 and the connecting component 20 to prevent direct contact between them and to provide insulation.

[0052] In some embodiments, the fixing assembly 50 includes a clamping member 51 mounted on the inner wall of the insulating cavity 41, the clamping member 51 having a clamping hole 52 through it, and an insulating member 60 sleeved on one of the connectors 21 on the connecting assembly 20, the connector 21 passing through the clamping hole 52, so as to support the connector 21 by the clamping member 51 and to insulate it by the insulating member 60 sleeved on the connector 21.

[0053] Specifically, the clamping hole 52 is a U-shaped hole with the opening facing upward in the second direction Y, and supports the bottom of the connecting component 20 in the second direction Y. At the same time, in the offshore wind power platform, due to the influence of waves, the outgoing structure will be subjected to loads along the second direction Y, which is the direction of gravity in actual application. Through the U-shaped hole, the connecting piece 21 of the connecting component 20 can bounce along the second direction Y in the U-shaped hole, so as to alleviate the load on the connecting component 20 and avoid the load acting directly on the connection between the connecting component 20 and the clamping piece 51, which would affect the supporting effect of the clamping piece 51 on the connecting component 20.

[0054] Specifically, in this embodiment, multiple clamping members 51 are included, all of which are disposed on the first connecting member 24 of the connecting assembly 20. All clamping members 51 are spaced apart along the first direction X and located on the connecting portions 22 of the first connecting member 24, so that the first connecting member 24 is supported by the multiple clamping members 51. Since the second connecting member 25 extends longitudinally along the second direction Y, and the load on the second connecting member 25 in the first direction X is relatively small, only the first connecting member 24 needs to be fixed.

[0055] In a specific embodiment, the fixing component 50 further includes a plurality of fixing members 53, which correspond one-to-one with a plurality of clamping members 51. The fixing members 53 are L-shaped, and one end of the fixing member 53 is fixedly installed on the inner wall of the insulating cavity 41, while the other end is connected to the corresponding clamping member 51, so as to fix the corresponding clamping member 51 on the inner wall of the insulating cavity 41 through the fixing member 53.

[0056] In offshore wind power platforms, waves can affect not only the connection between the connecting component 20 and the fixed component 50, but also the connection between the connecting component 20 and the lead wire 10 and the cable terminal 30. For example, long-term exposure to the loads exerted by waves can cause the connection between the connecting component 20 and the lead wire 10 and the cable terminal 30 to detach, affecting the transmission of electrical energy.

[0057] Therefore, in some embodiments, the outgoing cable structure further includes a flexible element 62. One end of the connecting component 20 is connected to the lead wire 10 through the flexible element 62, so that while maintaining the connection between the connecting component 20 and the lead wire 10, the deformation of the flexible element 62 itself can reduce the impact of waves. For example, the flexible element 62 is a flexible copper sheet. In addition to electrically connecting the connecting component 20 and the lead wire 10, the flexible copper sheet can also eliminate positional changes between the connecting component 20 and the lead wire 10 through its own deformation, thereby ensuring the connection effect between the connecting component 20 and the lead wire 10.

[0058] Furthermore, the other end of the connecting component 20 is also connected to the cable terminal 30 via the flexible element 62, so as to eliminate the relative displacement between the connecting component 20 and the cable terminal 30 and ensure the effectiveness of the support between the connecting component 20 and the cable terminal 30. It should be noted that in other embodiments, the connecting component 20 and the lead wire 10 can be connected via the flexible element 62, while the connecting component 20 and the cable terminal 30 can be directly rigidly connected, or the connecting component 20 and the lead wire 10 can be rigidly connected, while the connecting component 20 and the cable terminal 30 can be connected via the flexible element 62.

[0059] In some embodiments, since the lead wire 10 needs to pass through the outside of the housing 40 and into the insulating cavity 41 inside the housing 40, the lead wire 10 may come into contact with the housing 40, causing electrical energy on the lead wire 10 to leak into the housing 40. Therefore, the lead wire structure also includes an insulating sleeve 61 sleeved on the lead wire 10 to insulate the lead wire 10 from the housing 40. Optionally, the insulating sleeve 61 is an oil-oil sleeve, meaning both ends of the insulating sleeve 61 are immersed in insulating oil to improve the insulation effect of the insulating sleeve 61.

[0060] The insulating sleeve 61 is arranged parallel to the cable terminal 30, and both extend longitudinally along the second direction Y. In traditional outgoing cable structures, the insulating sleeve 61 is usually placed horizontally, intersecting the extension direction of the cable terminal 30, so that the lead wire 10 inside the insulating sleeve 61 can be directly connected to the cable terminal 30. However, in offshore wind power platforms, the outgoing cable structure is subjected to loads from waves for a long time. Therefore, the horizontally placed insulating sleeve 61 is subject to vertical loads and interferes with other components, causing the insulating sleeve 61 to fall off and leak oil. By placing the insulating sleeve 61 along the second direction Y, that is, along the vertical direction, even if subjected to vertical loads, the degree of interference between the insulating sleeve 61 and other components is reduced, ensuring the reliability of the insulating sleeve 61. The reason for placing the cable terminal 30 along the second direction Y is the same as that for the insulating sleeve 61, and will not be elaborated here.

[0061] The above-mentioned outgoing line structure has at least the following advantages:

[0062] The lead-out line 10 and the cable terminal 30 are connected by a connecting component 20, so that the electrical energy output by the electrical equipment is transmitted to the cable terminal 30 through the connecting component 20, and finally transmitted to other electrical equipment through the cable terminal 30. The connecting component 20 includes multiple sequentially connected connectors 21 along its longitudinal direction. Adjacent connectors 21 are detachable. By disassembling the connecting component 20 into multiple connectors 21, the lead-out line 10 and the cable terminal 30 can be connected to the connectors 21 at both ends of the connecting component 20 respectively. Then, the remaining connectors 21 are gradually assembled together, so that the assembled connecting component 20 can adapt to the position of the lead-out line 10 and the cable terminal 30 to meet the installation requirements of offshore wind power platforms.

[0063] This application also provides an electrical device that includes the outgoing line structure as described in any of the preceding claims, and through the aforementioned outgoing line structure, the power transmission between the electrical device and other devices is made more stable, which can meet the installation and use requirements of offshore wind power platforms.

[0064] Optionally, the above-mentioned electrical equipment is a three-phase integrated parallel reactor. In other embodiments, the above-mentioned electrical equipment may also be a transformer or transformer, etc., which is not limited here.

[0065] This application also provides a wind power device, which includes the electrical equipment as described in any of the above embodiments. Since the wind power device includes all the technical features of the aforementioned electrical equipment, it possesses all the technical effects of the aforementioned electrical equipment, and will not be elaborated further here. Optionally, the above-mentioned wind power device is a wind power device for offshore wind power, and through the above-mentioned outgoing line structure, it is made more adaptable to the installation and use of offshore wind power platforms.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
