Description

Technical Field

[0001] This application relates to the field of ring main unit technology, and in particular to an assembled frame for emergency repair of 10kV ring main units. Background Technology

[0002] Ring main units, prefabricated substations, and branch boxes are widely used in urban power distribution networks, and their stable and reliable operation is directly related to power supply security.

[0003] Currently, the main methods for providing installation foundations for these devices (especially 10kV ring main units) include concrete pouring and slag brick masonry foundations. However, these two traditional methods have the following obvious drawbacks in on-site emergency repair scenarios: concrete pouring requires on-site formwork, pouring, and long-term curing and solidification, while slag brick masonry requires brick-by-brick masonry and finishing, neither of which can meet the strict requirements for power restoration time in emergency power repairs; moreover, concrete foundations are large in volume and heavy in weight, and once formed, they are difficult to move, while brick foundations are made of scattered materials, making them inconvenient for rapid transportation, loading and unloading, and flexible on-site deployment as standby emergency supplies; in addition, traditional foundations are mostly disposable structures, often abandoned after the repair task is completed, and cannot be disassembled and reused, resulting in material waste and increased subsequent cleanup costs.

[0004] Therefore, in the face of emergencies such as floods, when it is necessary to quickly restore power to important users such as hospitals, communication hubs, and emergency command centers, there is an urgent need for an emergency equipment foundation that can be quickly erected, is easy to transport and store, and has sufficient mechanical strength and electrical insulation performance to replace the traditional foundation and significantly shorten the repair time.

[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0028] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this application.

[0029] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0030] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0031] In recent years, the negative impacts of human activities on the ecological environment have become increasingly apparent. Excessive deforestation, grazing, fishing, and industrial emissions have exacerbated the greenhouse effect, and abnormal atmospheric circulation has led to frequent natural disasters such as floods and typhoons in some areas. The application of ring main units, prefabricated substations, and branch boxes in various cities has become commonplace. As the main power supply equipment in urban areas, their safety and aesthetic performance cannot be underestimated. They can maintain the reliability of power supply operation and add a touch of style to the city. The foundations of existing operating power supply equipment are hidden underground, and some users' power supply equipment is even built in basements. Once a flood occurs, underground equipment cannot escape the risk of being submerged. Important electrical equipment such as hospitals, communications, and emergency command centers may face power outages. Temporary power generation equipment cannot maintain the operating load of normal equipment. Therefore, there is an urgent need for reliable power supply equipment to provide a stable power supply to meet the demand for high-load, high-quality power supply.

[0032] In related technologies, for routine emergency repairs and power supply tasks of 10kV and below power distribution lines and equipment, as well as emergency rescue and power supply tasks during severe weather, the main methods for emergency repairs of 10kV and below power distribution lines and equipment are concrete pouring and slag ash brick masonry foundations. These methods are time-consuming and labor-intensive, and cannot meet the time requirements for emergency repairs. In addition, concrete pouring foundations are not convenient for manual handling.

[0033] To address the aforementioned problems, this application proposes an assembled frame for emergency repair of 10kV ring main units. The embodiments of this application will be further described below with reference to the accompanying drawings.

[0034] Reference Figures 1 to 2This application provides an assembled frame for emergency repair of a 10kV ring main unit, including a column assembly, a beam assembly, a diagonal support assembly, and an SMC insulation assembly 140. The column assembly, beam assembly, and diagonal support assembly are all made of steel. The column assembly includes a first base column 110, a second base column 111, a third base column 112, and a fourth base column 113. The beam assembly includes a first connecting beam 120, a second connecting beam 121, a third connecting beam 122, and a fourth connecting beam 123. The diagonal support assembly includes at least two sets of double-crossing diagonal columns. One end of the first connecting beam 120 is connected to the top of the first base column 110, and the other end of the first connecting beam 120 is connected to the top of the second base column 111. One end of the second connecting beam 121 is connected to the top of the second base column 111. The other end of the second connecting beam 121 is connected to the top of the third foundation column 112, one end of the third connecting beam 122 is connected to the top of the third foundation column 112, the other end of the third connecting beam 122 is connected to the top of the fourth foundation column 113, one end of the fourth connecting beam 123 is connected to the top of the fourth foundation column 113, and the other end of the fourth connecting beam 123 is connected to the top of the first foundation column 110. Two sets of double-crossing diagonal columns are respectively located between the second foundation column 111 and the third foundation column 112, and between the first foundation column 110 and the second foundation column 111. The SMC insulation component 140 includes multiple SMC aluminum-plastic insulation composite panels, which enclose a fully enclosed structure. The column component, beam component, and diagonal support component are all located inside the SMC insulation component 140.

[0035] It should be noted that the first connecting beam 120 and the third connecting beam 122 are symmetrically arranged, and the second connecting beam 121 and the fourth connecting beam 123 are symmetrically arranged.

[0036] It should be noted that the assembled frame for emergency repair of 10kV ring main units in this application is designed to reduce the construction time of brick-concrete and reinforced concrete equipment foundations, shorten the power restoration time for important users, and ensure the normal operation of important units during disasters. The fully enclosed SMC insulation components 140 ensure good insulation performance at all times, preventing friction with sharp objects. SMC is an abbreviation for Sheet Molding Compound, whose main raw materials consist of GF (special yarn), UP (unsaturated resin), low-shrinkage additives, MD (filler), and various auxiliaries.

[0037] It should be noted that the various components in this application are assembled and connected using 16×50mm bolts.

[0038] In this application, the 10kV ring main unit 200 requiring emergency repair is installed on top of an assembled frame. That is, the ring main unit is located on an SMC aluminum-plastic insulation composite plate above the first connecting beam 120, the second connecting beam 121, the third connecting beam 122, and the fourth connecting beam 123. The steel column assembly, beam assembly, and diagonal support assembly are easy to handle manually and suitable for long-term storage. The column assembly, beam assembly, diagonal support assembly, and SMC insulation assembly 140 are all easy to manufacture and install, easy to handle by machinery and manual labor, and also easy to store emergency repair equipment. The double-crossing diagonal column is a structural design that can improve the stability and seismic resistance of the building. The SMC aluminum-plastic insulation composite plate, as the basic insulation material, has a stable structure and is easy to cut and assemble. At the same time, the steel column assembly, beam assembly, and diagonal support assembly reduce the equipment foundation manufacturing time. This application, through this design, allows for the long-term storage of emergency equipment, while maintaining a lighter weight under load conditions, facilitating mechanical and manual handling. Simultaneously, the materials are easy to process and manufacture, shortening repair time, increasing the power demand for emergency repairs, and ensuring the normal operation of important units during disasters.

[0040] Reference Figure 1Understandably, the crossbeam assembly also includes a fifth connecting crossbeam 124, a sixth connecting crossbeam 125, a seventh connecting crossbeam 126, and an eighth connecting crossbeam 127. One end of the fifth connecting crossbeam 124 is connected to the bottom of the first foundation column 110, and the other end of the fifth connecting crossbeam 124 is connected to the bottom of the second foundation column 111. One end of the sixth connecting crossbeam 125 is connected to the bottom of the second foundation column 111, and the other end of the sixth connecting crossbeam 125 is connected to the bottom of the third foundation column 112. The seventh connecting beam 126 is connected at one end to the bottom of the third foundation column 112, and at the other end to the bottom of the fourth foundation column 113. The eighth connecting beam 127 is connected at one end to the bottom of the fourth foundation column 113, and at the other end to the bottom of the first foundation column 110. The bottom of the fifth foundation column 114 is connected to the sixth connecting beam 125, and the bottom of the sixth foundation column 115 is connected to the eighth connecting beam 127.

[0041] In this embodiment, the fifth connecting beam 124 and the seventh connecting beam 126 are symmetrically arranged, and the sixth connecting beam 125 and the eighth connecting beam 127 are symmetrically arranged; the first connecting beam 120, the second connecting beam 121, the third connecting beam 122, the fourth connecting beam 123, the fifth connecting beam 124, the sixth connecting beam 125, the seventh connecting beam 126 and the eighth connecting beam 127 are all made of 180mm×68mm×7mm channel steel.

[0042] In some embodiments, the SMC insulation assembly 140 includes five SMC aluminum-plastic composite insulation panels, which are respectively a first SMC aluminum-plastic composite panel, a second SMC aluminum-plastic composite panel, a third SMC aluminum-plastic composite panel, a fourth SMC aluminum-plastic composite panel, and a fifth SMC aluminum-plastic composite panel. The first SMC aluminum-plastic composite panel is covered on one side formed by the sequential connection and enclosure of the first foundation column 110, the fifth connecting beam 124, the second foundation column 111, and the first connecting beam 120. The second SMC aluminum-plastic composite panel is covered on one side formed by the sequential connection and enclosure of the second foundation column 111, the second connecting beam 121, the third foundation column 112, and the sixth connecting beam 125. The third SMC aluminum-plastic composite panel is covered on one side formed by the sequential connection and enclosure of the third foundation column 112, the third connecting beam 122, the fourth foundation column 113, and the seventh connecting beam 126. The fourth SMC aluminum-plastic composite panel is covered on the other side.

The sixth SMC aluminum-plastic insulating composite panel is covered on the bottom of the side formed by the sequential connection of the fifth connecting beam 124, a sixth connecting beam 125, a seventh connecting beam 126, and an eighth connecting beam 127. The embodiments of this application are not limited here.

[0043] Reference Figure 1It is understood that the diagonal support assembly includes six sets of double-crossing diagonal columns. These six sets of double-crossing diagonal columns are: the first set 130, the second set 131, the third set 132, the fourth set 133, the fifth set 134, and the sixth set 135. The two ends of the first set 130 are connected to the second foundation column 111 and the fifth foundation column 114, respectively. The two ends of the second set 131 are connected to the fifth foundation column 114, respectively. Column 114 is connected to the third foundation column 112. The two ends of the third group of double-crossing diagonal columns 132 are connected to the third foundation column 112 and the fourth foundation column 113, respectively. The two ends of the fourth group of double-crossing diagonal columns 133 are connected to the fourth foundation column 113 and the sixth foundation column 115, respectively. The two ends of the fifth group of double-crossing diagonal columns 134 are connected to the sixth foundation column 115 and the first foundation column 110, respectively. The two ends of the sixth group of double-crossing diagonal columns 135 are connected to the first foundation column 110 and the second foundation column 111, respectively.

[0044] It should be noted that by setting double-crossing diagonal columns on each side, the stability and earthquake resistance of the building are further improved.

[0045] Reference Figure 1 It is understandable that the first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are all rectangular tubes.

[0046] It should be noted that the rectangular tube shape is closer to that of the reinforced concrete equipment foundation column, and the side facade is flat, making it easier to weld connecting components. The first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are all vertical columns, and the vertical columns use 200mm×200mm×5mm rectangular tubes.

[0047] Reference Figure 1 It is understandable that each set of double-crossing diagonal columns includes two intersecting diagonal support columns, and each diagonal support column is an angle steel with an outer cross-sectional dimension of 50mm×50mm×5mm.

[0048] It should be noted that the angle iron diagonal bracing reinforcement uses galvanized angle steel with an outer cross-sectional dimension of 50mm×50mm×5mm as the diagonal support column.

[0049] Reference Figure 1It is understandable that the lengths of the second connecting beam 121, the fourth connecting beam 123, the sixth connecting beam 125, and the eighth connecting beam 127 are all 4500mm, the lengths of the first connecting beam 120, the third connecting beam 122, the fifth connecting beam 124, and the seventh connecting beam 126 are all 1400mm, and the lengths of the first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are all 1200mm.

[0050] In this embodiment, since the commonly used 10kV ring main unit 200 has a length of 3500mm-4200mm, and with a 150mm allowance on each side of the foundation, the lengths of the second connecting beam 121, the fourth connecting beam 123, the sixth connecting beam 125, and the eighth connecting beam 127 are determined to be 4500mm; since the commonly used 10kV ring main unit 200 has a length of 1200mm-1300mm, and with a 50mm allowance on each side of the foundation, the lengths of the first connecting beam 120, the third connecting beam 125, and the fourth connecting beam 123 are determined to be 4500mm. The lengths of beam 122, the fifth connecting beam 124, and the seventh connecting beam 126 are 1400mm. Referring to the standard 10kV cable bending radius statistics table, the largest standard 10kV cable used by non-industrial users is YJLV22-3×300, with a bending radius of 1155mm. Therefore, the heights of the first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are determined to be 1200mm.

[0051] It should be noted that the foundation dimensions of the 10kV ring main unit 200 emergency repair modular equipment are consistent with the foundation standards for various equipment, with a specification of 4500mm. Measuring 1500mm x 1200mm, it features flexibility, ease of disassembly and assembly, high load-bearing capacity, convenient transportation, and stability and reliability. Its small size and light weight also make it suitable for long-term storage as a spare part in emergency repairs. Faced with an emergency repair project, the equipment foundation construction can be completed within 22 minutes. The remaining installation, commissioning, and power restoration work will be completed at normal speed, and the entire emergency repair operation will be finished in just 16.5 hours, restoring power to critical sectors as quickly as possible. (Reference) Figures 1 to 2This application provides an assembled frame for emergency repair of a 10kV ring main unit, including a column assembly, a beam assembly, a diagonal support assembly, and an SMC insulation assembly 140. The column assembly, beam assembly, and diagonal support assembly are all made of steel.

The diagonal support assembly includes at least two sets of double-crossing diagonal columns. One end of the first connecting beam 120 is connected to the top of the first base column 110, and the other end of the first connecting beam 120 is connected to the top of the second base column 111. One end of the second connecting beam 121 is connected to the top of the second base column 111.

Two sets of double-crossing diagonal columns are respectively located between the second foundation column 111 and the third foundation column 112, and between the first foundation column 110 and the second foundation column 111. The SMC insulation component 140 includes multiple SMC aluminum-plastic insulation composite panels, which enclose a fully enclosed structure. The column component, beam component, and diagonal support component are all located inside the SMC insulation component 140.

[0052] It should be noted that the first connecting beam 120 and the third connecting beam 122 are symmetrically arranged, and the second connecting beam 121 and the fourth connecting beam 123 are symmetrically arranged.

[0053] It should be noted that the assembled frame for emergency repair of 10kV ring main units in this application is used to reduce the construction time of brick-concrete and reinforced concrete equipment foundations, shorten the power restoration time for important users, and ensure the normal operation of important units during disasters; through the insulation enclosure of the fully enclosed SMC insulation component 140, its insulation performance must always be maintained in good condition to avoid scratching with sharp objects.

[0054] It should be noted that the various components in this application are assembled and connected using 16×50mm bolts.

[0055] In this application, the 10kV ring main unit 200 requiring emergency repair is installed on top of an assembled frame. That is, the ring main unit is located on an SMC aluminum-plastic insulation composite plate above the first connecting beam 120, the second connecting beam 121, the third connecting beam 122, and the fourth connecting beam 123. The steel column assembly, beam assembly, and diagonal support assembly are easy to handle manually and suitable for long-term storage. The column assembly, beam assembly, diagonal support assembly, and SMC insulation assembly 140 are all easy to manufacture and install, easy to handle by machinery and manual labor, and also easy to store emergency repair equipment. The double-crossing diagonal column is a structural design that can improve the stability and seismic resistance of the building. The SMC aluminum-plastic insulation composite plate, as the basic insulation material, has a stable structure and is easy to cut and assemble. At the same time, the steel column assembly, beam assembly, and diagonal support assembly reduce the equipment foundation manufacturing time. This application, through this design, allows for the long-term storage of emergency equipment, while maintaining a lighter weight under load conditions, facilitating mechanical and manual handling.

[0060] Reference Figure 1It is understood that the diagonal support assembly includes six sets of double-crossing diagonal columns. These six sets of double-crossing diagonal columns are: the first set 130, the second set 131, the third set 132, the fourth set 133, the fifth set 134, and the sixth set 135. The two ends of the first set 130 are connected to the second foundation column 111 and the fifth foundation column 114, respectively. The two ends of the second set 131 are connected to the fifth foundation column 114, respectively. Column 114 is connected to the third foundation column 112. The two ends of the third group of double-crossing diagonal columns 132 are connected to the third foundation column 112 and the fourth foundation column 113, respectively. The two ends of the fourth group of double-crossing diagonal columns 133 are connected to the fourth foundation column 113 and the sixth foundation column 115, respectively. The two ends of the fifth group of double-crossing diagonal columns 134 are connected to the sixth foundation column 115 and the first foundation column 110, respectively. The two ends of the sixth group of double-crossing diagonal columns 135 are connected to the first foundation column 110 and the second foundation column 111, respectively.

[0061] It should be noted that by setting double-crossing diagonal columns on each side, the stability and earthquake resistance of the building are further improved.

[0062] Reference Figure 1 It is understandable that the first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are all rectangular tubes.

[0063] It should be noted that the shape of the square and rectangular tube is closer to that of the foundation column of the reinforced concrete equipment, and the side facade is flat, making it easier to weld the connecting components.

[0064] The first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are all vertical columns, and the vertical columns are made of 200mm×200mm×5mm square and rectangular tubes.

[0065] Reference Figure 1 It is understandable that each set of double-crossing diagonal columns includes two intersecting diagonal support columns, and each diagonal support column is an angle steel with an outer cross-sectional dimension of 50mm×50mm×5mm.

[0066] It should be noted that the angle iron diagonal bracing reinforcement uses galvanized angle steel with an outer cross-sectional dimension of 50mm×50mm×5mm as the diagonal support column.

[0067] Reference Figure 1It is understandable that the lengths of the second connecting beam 121, the fourth connecting beam 123, the sixth connecting beam 125, and the eighth connecting beam 127 are all 4500mm, the lengths of the first connecting beam 120, the third connecting beam 122, the fifth connecting beam 124, and the seventh connecting beam 126 are all 1400mm, and the lengths of the first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are all 1200mm.

[0068] In this embodiment, since the commonly used 10kV ring main unit 200 has a length of 3500mm-4200mm, and with a 150mm allowance on each side of the foundation, the lengths of the second connecting beam 121, the fourth connecting beam 123, the sixth connecting beam 125, and the eighth connecting beam 127 are determined to be 4500mm; since the commonly used 10kV ring main unit 200 has a length of 1200mm-1300mm, and with a 50mm allowance on each side of the foundation, the lengths of the first connecting beam 120, the third connecting beam 125, and the fourth connecting beam 123 are determined to be 4500mm. The lengths of beam 122, the fifth connecting beam 124, and the seventh connecting beam 126 are 1400mm. Referring to the standard 10kV cable bending radius statistics table, the largest standard 10kV cable used by non-industrial users is YJLV22-3×300, with a bending radius of 1155mm. Therefore, the heights of the first foundation column 110, the second foundation column 111, the third foundation column 112, the fourth foundation column 113, the fifth foundation column 114, and the sixth foundation column 115 are determined to be 1200mm.

[0069] It should be noted that the foundation dimensions of the 10kV ring main unit 200 emergency repair modular equipment are consistent with the standards for foundations of various equipment, with specifications of 4500mm x 1500mm x 1200mm. It features flexibility, ease of use, rapid disassembly and construction, strong load-bearing capacity, convenient transportation, and stable reliability. Its small size and light weight also facilitate long-term storage as a spare part for emergency repairs. For emergency repair projects, the foundation construction can be completed within 22 minutes. The remaining installation, commissioning, and power supply work are completed at normal speed, and the entire emergency repair work can be completed in just 16.5 hours, restoring power to critical sectors as quickly as possible.
