Description

Technical Field

[0001] This invention relates to the field of auxiliary technology for power equipment transportation and installation, specifically a support bracket for phase switching of an ultra-high voltage reactor. Background Technology

[0002] In ultra-high voltage power transmission projects, shunt reactors are important reactive power compensation devices.

[0003] Taking the BKD-160000 / 1000 type reactor as an example, the single unit has a capacity of 160Mvar, a weight of about 175t, and a height of about 19m. The high voltage bushing is slender and made of ceramic or composite materials, which has limited bending resistance.

[0004] When an internal fault occurs in the operating phase reactor (such as a continuous increase in acetylene in the oil), the standby phase reactor needs to be completely replaced at the faulty phase foundation location, a process known as "complete phase replacement." To shorten the power outage time (usually only about 12 days), the reactor body is transported as a whole with transformer oil during phase replacement without disassembly and oil draining. This places extremely high demands on the safety of the equipment during transportation.

[0005] During the phase-change process, the high-voltage outgoing line device and the riser are localized weak points of the equipment. This area, located between the bushing root and the tank body, bears the dual effects of the bushing cantilever load and transportation vibration impact, making it highly susceptible to stress concentration, which can lead to damage or even breakage of the bushing root. In current engineering practice, no dedicated temporary reinforcement structure has been installed for this weak point. The main approach relies on passive monitoring methods such as installing a 3D impact recorder on the top of the bushing for acceleration monitoring and an inclinometer on the main body, lacking proactive mechanical support and protective measures.

[0006] In the existing technology, the devices related to the transportation support of large power equipment mainly have the following shortcomings: First, the stiffness is not adjustable. The support structure mostly uses fixed rod connections, and once the stiffness is determined, it cannot be adjusted. This makes it difficult to flexibly match the optimal support stiffness according to changing factors such as reactor model, bushing weight, and transportation route conditions. If the stiffness is too high, the impact force during transportation is directly transmitted to the bushing root, exacerbating local stress; if the stiffness is too low, it cannot provide effective restraint. This "one-size-fits-all, fixed-stiffness" approach results in poor versatility of the support system, requiring different models of equipment to be designed and manufactured separately.

[0007] Secondly, the disassembly and assembly are inefficient and pose a risk of secondary damage. Traditional support structures often employ welding or integral designs, requiring large welding or cutting equipment for on-site installation and disassembly, resulting in long operation times and potentially occupying valuable power outage work windows. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a support bracket for the integrated phase switching of ultra-high voltage reactors. It solves the problems of poor versatility caused by the fixed and unadjustable stiffness of existing support structures, the inability to flexibly match the optimal stiffness according to the reactor model and transportation conditions, and the low on-site disassembly and assembly efficiency and easy secondary damage to equipment caused by traditional welded or integral structures.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A support bracket for commutation of an ultra-high voltage reactor includes: a bottom support, a flexible connector, a first connector, and a second connector. The flexible connector includes a connecting body, on the side of which a first connecting column and a second connecting column are fixedly disposed. The first connecting column is rotatably connected to an auxiliary bracket fixedly disposed on the bottom support, and the second connecting column engages with a sliding hole on the auxiliary bracket. The end of the second connecting column is threadedly connected to a second nut head with vibration detection function, and the connection stiffness of the flexible connector is adjusted by the preload of the second nut head and the auxiliary bracket. The first connector is connected to the first side of the connecting body, the second connector is connected to the second side of the connecting body, and the second connector is close to the second connecting post.

[0010] Preferably, the bottom support component includes: a portal frame bracket and a height-adjustable bottom support component installed on the top of the portal frame bracket. The height-adjustable bottom support component includes a bottom support body. The top of the bottom support body has a mating recess. At least two screw components are fixedly connected to the bottom of the bottom support body. The bottom end of the screw component passes through a pre-reserved through hole in the top of the portal frame bracket, and the screw component is fixedly connected to the top of the portal frame bracket using upper and lower double nuts.

[0011] Preferably, the gate-shaped bracket includes: two corresponding uprights, the top ends of the two uprights are connected to a top plate, and the bottom end of each upright is fixedly connected to a mounting plate; Auxiliary supports are fixedly connected between the top plate and the two column members, and a stabilizing crossbar is fixedly connected between the two auxiliary supports. Each of the aforementioned column members has an auxiliary bracket fixedly connected to its side and below the auxiliary support.

[0012] Preferably, the end of the first connecting post is threaded with a first nut head.

[0013] Preferably, an ear-shaped connector is provided on the first side of the connecting body; The first connector is rod-shaped, with one end rotatably connected to the ear-shaped connector and the other end fixedly connected to the main body of the ultra-high voltage reactor through a U-shaped locking member.

[0014] Preferably, an ear-shaped connector is provided on the first side of the connecting body; The first connector includes a right-angled component, the corner of which is rotatably connected to the ear-shaped connector.

[0015] Preferably, the right-angled component includes a first component and a second component, the first end of the first component and the first end of the second component intersect and are fixed, and a connecting seat is provided at the intersection of the first end of the first component and the first end of the second component; Both the second end of the first piece and the second end of the second piece are threadedly connected to an extension rod. The extension rod includes a threaded section and a connecting rod section, with the threaded section and the connecting rod section being integrally formed.

[0016] Preferably, a second connecting portion is provided on the second side of the connecting body; The second connector includes: The diagonal brace has a fixed bottom end with a connecting and mating seat corresponding to the second connecting part; A frame connector, the back of which is fixedly connected to the top of the diagonal brace, the frame connector includes a back plate and two side plates, and the side plates have connection holes on their sides; A flexible fastener, the two ends of which are respectively connected to the corresponding connecting holes on the two side plates.

[0017] Preferably, the flexible fastener includes a steel wire rope, with long screws fixedly connected to both ends of the steel wire rope. The long screws pass through the connecting holes on the side plate and are fixed to the side plate using double nuts.

[0018] Preferably, the connecting seat is mounted on the second connecting part and is fixedly connected by a pin.

[0019] This invention provides a support bracket for the overall commutation of an ultra-high voltage reactor. It has the following beneficial effects: 1. This invention employs a flexible connecting seat as the core connecting hub, and sets a first connecting column and a second connecting column on its connecting body. The first connecting column is rotatably connected to the auxiliary support, while the second connecting column is slidably engaged with the sliding hole. Simultaneously, a second nut head with vibration detection function is provided at the end of the second connecting column. The connection stiffness can be flexibly adjusted by adjusting the preload of the second nut head and the auxiliary support. Therefore, the support stiffness of the support can be dynamically matched according to the reactor model, bushing weight, and transportation route conditions, avoiding the problems of traditional fixed stiffness supports where excessive stiffness leads to direct transmission of impact force to the bushing root, or insufficient stiffness fails to effectively limit movement. This significantly improves the versatility and transportation safety of the support. Furthermore, the vibration detection function integrated into the nut head can provide real-time feedback of vibration data during stiffness adjustment, providing operators with quantitative basis for stiffness-flexibility adjustment and achieving synergistic optimization of support stiffness and vibration isolation effect.

[0020] 2. This invention designs a first connector and a second connector to be connected to the first and second sides of the connecting body, respectively, with the second connector positioned close to the second connecting post, forming an asymmetrical force distribution. This allows for differentiated stiffness distribution on both sides of the flexible connecting seat—the stiffness on the side closer to the second connecting post can be actively adjusted via the second nut head, while the side closer to the first connecting post maintains a stable rotational connection. This enables selective control of the overall stiffness distribution of the support, better matching the vibration and impact characteristics in different directions during reactor commutation transport. Furthermore, the sliding fit between the second connecting post and the sliding hole generates a slight buffer displacement under vibration and impact, further enhancing the support's adaptability to complex road conditions and its impact resistance.

[0021] 3. This invention employs a modular assembly structure, designating the bottom support, flexible connecting seat, first connecting component, and second connecting component as detachable independent parts. These components are connected on-site via rotational connections, sliding fits, and threaded connections, enabling rapid assembly without the need for welding or large cutting equipment. Consequently, the installation and disassembly of the support can be completed quickly, significantly improving on-site construction efficiency and avoiding the occupation of valuable power outage work windows. Simultaneously, the detachable connection method prevents secondary damage to the reactor body and bushing root caused by high welding temperatures or cutting vibrations, effectively protecting the equipment's weak points and further enhancing the safety and reliability of the overall commutation process.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0025] like Figure 1 As shown, during the phase-changing process, the main body b of the UHV reactor has a high-voltage outgoing line device a on one side. Generally, the bushing of the high-voltage outgoing line device a is slender and made of ceramic or composite materials, with limited bending resistance. It is subjected to the dual effects of bushing cantilever load and transportation vibration impact, and is very prone to damage or even breakage at the bushing root due to stress concentration. At present, no special support brackets have been designed for this stage in the construction process. The method of using temporary steel pipes + welded supports has technical problems such as non-adjustable stiffness, low disassembly and assembly efficiency, and risk of secondary damage.

[0026] like Figures 1-10As shown, in order to solve the above-mentioned technical problems, this embodiment provides a support bracket for the overall commutation of an ultra-high voltage reactor, including a bottom support 1, a flexible connector 2, a first connector 3 and a second connector 4.

[0027] The bottom support 1 is used to support the bottom of the high-voltage outgoing line device a, and as the main body, it is used to connect the flexible connector 2, the first connector 3, and the second connector 4. The flexible connector 2 is flexibly installed on the bottom support 1. The first connector 3 is connected to the first side of the flexible connector 2, and the second connector 4 is connected to the second side of the flexible connector 2. The first connector 3 is fixedly installed to the main body of the UHV reactor or an additional bracket structure on the main body of the UHV reactor using a U-shaped locking device. This is used to stabilize the flexible connector 2 and maintain the connection strength of the bottom support 1. The second connector 4 is fixedly connected to the high-voltage outgoing line device a. This is used to stabilize the high-voltage outgoing line device a during the assembly and phase-changing process, reduce the vibration of the high-voltage outgoing line device a, avoid fatigue damage at the connection between the high-voltage outgoing line device a and the main body b of the UHV reactor, and prevent the rigid impact during transportation from directly damaging the high-voltage outgoing line device a.

[0028] Specifically, the flexible connector 2 includes a connecting body 201, which is a solid plate. A first connecting post 202 and a second connecting post 203 are fixedly provided on the side of the connecting body 201. The first connecting post 202 and the second connecting post 203 are provided on a pair of corresponding side surfaces (two side surfaces) of the connecting body 201. The first connecting post 202 is rotatably connected to the auxiliary bracket 109 fixedly provided on the bottom support 1, that is, the entire flexible connector 2 can rotate freely around the axis of the first connecting post 202. The second connecting post 203 is engaged with the sliding hole 1010 opened on the auxiliary bracket 109. This sliding engagement does not affect the overall rotational adjustment of the flexible connector 2.

[0029] The end of the second connecting post 203 is threaded with a second nut head 205 having vibration detection function. The connection stiffness of the flexible connector 2 is adjusted by the pre-tightening force between the second nut head 205 and the auxiliary support 109. That is, the second nut head 205 and the connecting body 201 are clamped on both sides of the auxiliary support 109. The user can adjust the clamping force / pre-tightening force on the auxiliary support 109 by rotating the second nut head 205. It can be understood that the second nut head 205 with vibration detection function is a combination structure of cap nut + vibration sensor. The end of the cap nut integrates a vibration sensor to monitor the vibration data of the cap nut, that is, to reflect the vibration status at the second connecting post 203. When the vibration data (frequency / amplitude) exceeds the preset threshold, the terminal device matched with the vibration sensor issues a prompt. The user can adjust the movement strategy during the assembly and phase change process or rotate the second nut head 205 to adjust the pre-tightening force between the second nut head 205 and the auxiliary support 109, thereby adjusting the connection stiffness of the flexible connector 2 to adapt to the current situation.

[0030] Generally speaking, when the overall stiffness of the support bracket is too high, the impact force during transportation is directly transmitted to the root of the casing, which exacerbates the local stress; when the stiffness is too low, it cannot provide effective limiting, and the root of the casing bears the cantilever load of the casing alone.

[0031] like Figure 9 As shown, the axis of the first connecting post 202 is point O. When the flexible connector 2 rotates as a whole, it rotates around point O. The sliding hole 1010 can be designed as a vertical slot-shaped hole. The diameter of the second connecting post 203 is slightly smaller than the width of the slot-shaped hole, allowing the second connecting post 203 to move along an arc-shaped motion trajectory centered on point O. Under the constraint of the sliding hole 1010, the swing range of the second connecting post 203 is limited. When the second nut head 205 suddenly fails, the flexible connector 2 can remain basically stable.

[0032] On the connecting body 201 of the flexible connector 2, the first connector 3 is connected to the first side of the connecting body 201, the second connector 4 is connected to the second side of the connecting body 201, and the second connector 4 is close to the second connecting post 203.

[0033] Understandably, the second connector 4, positioned near the second connecting column 203, can directly transfer external loads to the vicinity of the connection node between the second connecting column 203 and the auxiliary support 109, effectively shortening the load transfer path and reducing the bending and torsional moments borne by the connecting body 201, thereby improving the overall load-bearing stability of the support. The first connector 3 and the second connector 4 are connected to different sides of the connecting body 201, and their relative positions to the two connecting columns are opposite, giving the flexible connector 2 a clear spatial directionality. This asymmetrical structure facilitates quick identification of the connection direction during on-site installation, reduces the risk of incorrect installation, and improves disassembly and assembly efficiency.

[0034] Understandably, the difference in the distribution positions of the first connector 3 and the second connector 4 on the connecting body 201, combined with the adjustment of the preload at the second connecting post 203 by the second nut head 205, allows for differentiated stiffness distribution on different sides of the flexible connector 2. That is, the connection stiffness on the side closer to the second connecting post 203 can be actively adjusted by the second nut head 205, while the side closer to the first connecting post 202 maintains a relatively stable rotational connection state. This achieves selective control of the overall stiffness distribution of the support, better adapting to the vibration and impact characteristics in different directions during reactor commutation transport.

[0035] In one embodiment, the bottom support 1 includes: a gantry bracket and a height-adjustable bottom support mounted on the top of the gantry bracket. The height-adjustable bottom support can be freely adjusted during use, making the bottom support 1 more widely applicable.

[0036] Specifically, the height-adjustable base support includes a base body 106. The top of the base body 106 has a mating recess 107, within which a necessary elastic protective pad can be designed to stably support the horizontally extending bottom portion of the high-voltage output device a. At least two screw rods 108 are fixedly connected to the bottom of the base body 106. The bottom end of each screw rod 108 penetrates a pre-drilled hole in the top of the portal frame, and is fixedly connected to the top of the portal frame using upper and lower double nuts (two nuts located on the upper and lower sides of the top of the portal frame). By adjusting the two nuts in the upper and lower double nuts, the relative (height) position of the screw rod 108 and the top of the portal frame can be adjusted, thereby adjusting the height of the base body 106. During installation, the base body 106 is first placed below the horizontally extending bottom portion of the high-voltage output device a, and then the height of the base body 106 is adjusted to provide stable support.

[0037] In one embodiment, the portal frame includes: two corresponding upright members 101, the top ends of the two upright members 101 are connected to a top plate member 103, the two upright members 101 and the top plate member 103 form a portal shape, and a mounting plate 102 is fixedly connected to the bottom end of each upright member 101. The mounting plate 102 is fixedly installed with the moving carrier during the assembly and phase change process; auxiliary supports 104 are fixedly connected between the top plate member 103 and the two upright members 101, and a stabilizing crossbar 105 is fixedly connected between the two auxiliary supports 104. The design of the auxiliary supports 104 and the stabilizing crossbar 105 can increase the connection strength between the top plate member 103 and the upright members 101, as well as the overall structural strength of the portal frame.

[0038] Each column 101 has an auxiliary bracket 109 fixedly connected to its side and below the auxiliary support 104. The auxiliary bracket 109 is frame-shaped and is used to cooperate with the installation of the flexible connector 2.

[0039] In one embodiment, to prevent the first connecting post 202 from disengaging from the auxiliary bracket 109, a first nut head 204 is threadedly connected to the end of the first connecting post 202 to limit the axial movement of the flexible connector 2 along the first connecting post 202.

[0040] In one embodiment, an ear-shaped connector 206 is provided on the first side of the connecting body 201; multiple ear-shaped connectors 206 can be distributed to connect multiple first connectors 3.

[0041] Specifically, the first connector 3 is rod-shaped, with one end rotatably connected to the ear-shaped connector 206, and the other end fixedly connected to the main body of the ultra-high voltage reactor through a U-shaped locking member.

[0042] In another embodiment, the first connector 3 includes a right-angle member 301, the corner of which is rotatably connected to the ear-shaped connector 206. The right-angle member 301 has two connection points, enabling more stable installation.

[0043] Specifically, the right-angled component 301 includes a first component 3011 and a second component 3012. The first end of the first component 3011 and the first end of the second component 3012 intersect and are fixed. The included angle between the first component 3011 and the second component 3012 is 60°-120°. A connecting seat 3013 is provided at the intersection of the first end of the first component 3011 and the first end of the second component 3012. The connecting seat 3013 cooperates with the ear-shaped connecting component 206 and is rotated and installed using a pin.

[0044] The second end of the first piece 3011 and the second end of the second piece 3012 are both threadedly connected to an extension rod 302. The extension rod 302 includes a threaded section 3022 and a connecting rod section 3021, which are integrally formed.

[0045] Threaded holes are provided at the ends of the first piece 3011 and the second piece 3012, and the threaded section 3022 of the extension rod 302 is directly threaded into the threaded hole for installation.

[0046] In one embodiment, a second connecting part 207 is provided on the second side of the connecting body 201, and the second connecting part 207 is used to install the second connecting member 4.

[0047] Specifically, the second connector 4 includes: a diagonal brace 401, a mating seat 402, a frame connector 403, and a flexible fastener 404.

[0048] The bottom end of the diagonal brace 401 is fixedly provided with a connecting seat 402 corresponding to the second connecting part 207. The connecting seat 402 is a bayonet that is locked into the second connecting part 207 of the plate and is fixedly connected by a pin. This installation method makes the second connecting part 4 easy to disassemble as a whole, and the support bracket can be separated for transportation / storage.

[0049] The back of the frame connector 403 is fixedly connected to the top of the diagonal brace 401. The frame connector 403 includes a back plate 4031 and two side plates 4032. The side plates 4032 have connection holes 4033 on their sides. The two ends of the flexible fastener 404 are respectively connected to the corresponding connection holes 4033 on the two side plates 4032.

[0050] Multiple flexible fasteners 404 can be provided, which are used to fix the frame connector 403 to the vertical part of the high voltage output device a.

[0051] In one embodiment, the flexible fastener 404 includes a steel wire rope 4041, with long screws 4042 fixedly connected to both ends of the steel wire rope 4041. The long screws 4042 pass through the connecting holes 4033 on the side plate 4032, and the long screws 4042 and the side plate 4032 are fixed with double nuts.

[0052] The flexible structure of the 4041 steel wire rope can adapt to the vertical part of the high-voltage outgoing line device a with different cross-sectional shapes.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
