Description

Technical Field

[0001] The invention relates to the technical field of disconnect switches, in particular to an assembly rack for outdoor 220KV high-voltage disconnect switches. Background Art

[0002] The outdoor 220KV disconnector is a high-voltage switchgear, mainly used for isolating power supply, switching operation and maintenance safety measures in power systems. The operating mechanism separates or closes the moving contact and the static contact, thereby isolating or conducting the circuit. In the open state, a clear break is formed between the moving and static contacts, with sufficient insulation distance, which can reliably isolate the power supply and ensure the safety of maintenance personnel and equipment; in the closed state, the moving and static contacts are in close contact, so that the circuit forms a path and allows current to pass normally. The assembly frame of the outdoor disconnector will rust due to the erosion of rainwater during long-term use, which will affect the hardness of the assembly frame. When the assembly frame is hit by hail or other foreign objects, the assembly frame will be deformed, causing the insulator to shift. The insulator shift will make it impossible to accurately align the moving contact and the static contact, and good contact cannot be achieved when closing. This will reduce the contact area between the contacts, increase the contact resistance, and easily generate heat during operation, which accelerates the aging and damage of the contacts. In severe cases, local overheating may occur, causing the metal on the contact surface to melt, further worsening the contact condition, and even causing arcing, threatening the safe operation of the equipment.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. 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.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0032] Reference Figure 3-Figure 5, which is the first embodiment of the present invention, and provides an assembly stand for an outdoor 220KV high-voltage disconnector. The assembly stand for the outdoor 220KV high-voltage disconnector includes an assembly stand 101, an insulator 102 is provided on the assembly stand 101, a moving contact is provided on the top of the insulator 102, there are multiple insulators 102, which are evenly distributed in a straight line on both sides of the top of the assembly stand 101, a gate that can move up and down is provided on the top of the insulator 102 on one side, a moving contact is provided on the gate, and a driving component is provided on the gate for driving the gate to move up and down, so as to complete closing or opening, a metal rod 103 is provided at the bottom of the insulator 102, and the metal rod 103 is used to fix the insulator 102 on the assembly stand 101. The above are all existing technologies, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0033] The correction component 200 is arranged on the assembly frame 101. The number of the correction components 200 corresponds to the insulator 102, including an adjusting part 201. The adjusting part 201 includes a fixed box 2011 fixed to the top of the assembly frame 101. A threaded sleeve 2012 is rotatably connected to the fixed box 2011. The threaded sleeve 2012 is rotatably connected to the fixed box 2011 through a bearing. A threaded rod 2013 is connected to the inner thread of the threaded sleeve 2012. A spherical seat 2014 is fixed to the top of the threaded rod 2013. A spherical sleeve 2014 is provided on the outer side of the spherical seat 2014. The spherical sleeve 2015 is clamped with the spherical seat 2014. Through the cooperation of the two, the support plate 2016 can be tilted at any angle.

[0034] A support plate 2016 is fixed on the top of the spherical sleeve 2015, and the porcelain piece on the outside of the insulator 102 fits with the top of the support plate 2016. Except for the support plate 2016 and the outside of the fixing box 2011, there are four adjusting parts in the adjusting part 201, which are rectangular and evenly distributed at the four corners inside the fixing box 2011.

[0035] The assembly frame 101 is made of Q235B steel. After being used for a long time and rusting, when the assembly frame 101 is hit by hail or foreign objects, the impact force is transmitted to the installation position of the insulator 102 through the crossbeam of the assembly frame 101. The deformation is concentrated at the welding point between the assembly frame 101 and the metal rod 103, causing plastic deformation in this area. After deformation, the local concave amount of the crossbeam of the assembly frame 101 is ≥1.5mm, and the inclination angle of the metal rod 103 is ≥1.2°, resulting in an offset of the insulator 102 of ≥3mm.

[0036] When the assembly frame 101 is deformed, causing the insulator 102 to deflect, the threaded sleeve 2012 in the downward deflection direction of the insulator 102 will rotate, and drive the threaded rod 2013 to move upward. The threaded rod 2013 cooperates with the spherical sleeve 2015 and the spherical seat 2014 to push one side of the support plate 2016 to move upward, and pushes the porcelain part on the outside of the insulator 102 to rotate upward through the support plate 2016, so that the insulator 102 can be corrected and returned to its normal position. In this way, the contact connection part of the disconnector can be restored to a normal state, ensuring uniform contact pressure and stable contact area, keeping the contact resistance within a normal range, avoiding problems such as heating, oxidation and wear caused by increased contact resistance, and ensuring the stable conductive performance of the disconnector.

[0037] The thread pitches of the threaded rod 2013 and the threaded sleeve 2012 are relatively large, so when the threaded sleeve 2012 rotates at a relatively small angle, the threaded rod 2013 can move a relatively long distance.

[0038] The connection between the bottom of the insulator 102 and the metal rod 103 is achieved through an additional set of spherical sleeves 2015 connected to the spherical seat 2014. This ensures that the insulator 102 can adaptively rotate when pushed by the support plate 2016 without getting stuck. The support plate 2016 can support the insulator 102 to prevent the insulator 102 from shaking due to changes in the connection method.

[0039] The correction component 200 also includes a transmission part 202 and a trigger part 203. The number of the transmission parts 202 corresponds to the threaded sleeve 2012. The trigger part 203 includes a connecting seat 2031 threadedly connected to the bottom of the metal rod 103. A threaded hole is provided at the bottom of the metal rod 103. The top of the connecting seat 2031 is a threaded column. The connecting seat 2031 is connected and fixed to the metal rod 103 by threaded locking. A positioning seat 2032 is provided on the outer side of the connecting seat 2031. The positioning seat 2032 is clamped with the outer side of the connecting seat 2031. The positioning seat 2032 can be rotated at the bottom of the connecting seat 2031, and the two will not separate. A gravity ball 2033 is fixed to the bottom of the positioning seat 2032, and the gravity ball 2033 has a certain weight.

[0040] During use, since the positioning seat 2032 can rotate freely at the bottom of the connecting seat 2031, and under the influence of the gravity of the gravity ball 2033, the positioning seat 2032 will always remain in a downward vertical state. If the deformation of the assembly frame 101 causes the insulator 102 to tilt, the gravity ball 2033 and the positioning seat 2032 will remain stationary, and the connecting seat 2031 will rotate in the positioning seat 2032, and drive the threaded sleeve 2012 to rotate through the transmission member 202, so that the insulator 102 can be corrected. Example 2

[0041] Reference Figure 3 、 Figure 6 and Figure 7 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0042] Specifically, the transmission member 202 includes a connecting column 2021 fixed to the bottom of the threaded sleeve 2012, the bottom end of the connecting column 2021 extends to the bottom of the assembly frame 101, and the connecting column 2021 is used to drive the threaded sleeve 2012 to rotate. A rotating rod 2022 is provided on the outer side of the connecting column 2021, and a movable groove 2022-1 is provided in the rotating rod 2022. A clamping block 2023 is provided in the movable groove 2022-1. One side of the clamping block 2023 is inclined. A clamping slot is provided on the connecting column 2021. 2021-1, the block 2023 is engaged with the slot 2021-1, and the rotating rod 2022 is connected to the connecting column 2021 through the cooperation of the two, so that the rotating rod 2022 can drive the connecting column 2021 when rotating, and the connecting column 2021 drives the threaded sleeve 2012 to rotate. When the rotating rod 2022 rotates in the reverse direction to reset, the connecting column 2021 will not rotate in the reverse direction, thereby preventing the threaded sleeve 2012 from rotating in the reverse direction and causing the threaded rod 2013 to move downward.

[0043] There are multiple slots 2021-1, which are evenly distributed in a ring shape on the outside of the connecting column 2021. Through the arrangement of multiple slots 2021-1, the rotating rod 2022 can be rotated at any angle to make the block 2023 engage with the slot 2021-1. A first spring 2024 is fixed on one side of the block 2023, and the other end of the first spring 2024 is fixed to the inner wall of the movable groove 2022-1. The first spring 2024 is used to apply a thrust to the block 2023, so that the block 2023 and the slot 2021-1 are more firmly engaged.

[0044] Specifically, the correction component 200 also includes a pushing member 204, which includes a pressure plate 2041 fixed to the outside of the connecting seat 2031, a support frame 2042 is fixed to one side of the positioning seat 2032, and a push rod 2043 is inserted into the support frame 2042. The push rod 2043 is L-shaped, and the end is in contact with the rotating rod 2022. An extrusion block 2044 is inserted into the positioning seat 2032, and a slot is provided on the support frame 2042. The extrusion block 2044 is inserted into the slot, and one side of the extrusion block 2044 is inclined. The support frame 2042 is used to support and position the push rod 2043 and the extrusion block 2044, so that the two can maintain a horizontal state synchronously with the positioning seat 2032, and will not be offset due to the deformation of the assembly frame 101.

[0045] When the connecting seat 2031 rotates in the positioning seat 2032, since the positioning seat 2032 remains stationary, the connecting seat 2031 will drive the pressure plate 2041 to squeeze the top inclined surface of the extrusion block 2044, thereby pushing the extrusion block 2044 to move downward, and push the push rod 2043 to move through the inclined surface of the extrusion block 2044, so that the push rod 2043 pushes the rotating rod 2022 to rotate, and then the connecting column 2021 can drive the threaded sleeve 2012 to rotate, and the support plate 2016 can push the inclined side of the insulator 102 to move upward, so that the insulator 102 can be corrected.

[0046] The number of the pushing members 204 other than the pressing plate 2041 is four, and they are distributed in a ring shape outside the positioning seat 2032 . The pressing plate 2041 is in a ring shape.

[0047] When the assembly frame 101 is deformed, elastic potential energy is stored, which can be converted into kinetic energy of the rotating rod 2022 through the pusher 204. The rotating rod 2022 can then drive the connecting column 2021 and the threaded sleeve 2012 to rotate, thereby completing the adjustment of the insulator 102 tilt angle.

[0048] When hailstones hit the assembly frame multiple times and cause cumulative deformation, the gravity ball 2033 always triggers the pusher 204 through the positioning seat 2032, forming a closed-loop mechanism of "deformation-triggering-correction", which can meet the service life requirements of outdoor equipment.

[0049] Specifically, the correction component 200 also includes a locking piece 205, which includes a fixed frame 2051 fixed to the bottom of the assembly frame 101, and a locking block 2052 is inserted into the fixed frame 2051. The top side of the locking block 2052 is inclined, and a locking groove 103-1 is provided on the metal rod 103. When the metal rod 103 is inserted into the fixed frame 2051 and the bottom of the insulator 102 contacts the support plate 2016, the locking block 2052 will engage with the locking groove 103-1. Through the cooperation of the two, the metal rod 103 and the insulator 102 can be locked, so that the insulator 102 can be connected and fixed to the assembly frame 101.

[0050] The metal rod 103 and the fixing frame 2051 are both rectangular. When the metal rod 103 is inserted into the fixing frame 2051 , the angle of the insulator 102 can be aligned without adjusting the installation angle of the insulator 102 .

[0051] A mounting block 2053 is fixed to one side of the locking block 2052, and a second spring 2054 is fixed to one side of the mounting block 2053. The other end of the second spring 2054 is fixed to the fixing frame 2051. The mounting block 2053 is used to support the second spring 2054, and a pulling force is applied to the mounting block 2053 through the second spring 2054, and the locking block 2052 is driven to move through the mounting block 2053, so that the locking block 2052 can be more tightly engaged with the locking slot 103-1. A protective frame is fixed to the bottom of the fixing frame 2051.

[0052] Specifically, a slide rail 2025 is fixed to one side of the rotating rod 2022, a positioning shaft 2026 slides inside the slide rail 2025, a stabilizing column 2027 is fixed to the bottom end of the positioning shaft 2026, one end of the stabilizing column 2027 is inserted into the protective frame and is movably connected to the protective frame, a positioning block 2028 is fixed to the outside of the stabilizing column 2027, a third spring 2029 is fixed to one side of the positioning block 2028, and the other end of the third spring 2029 is fixed to the inner wall of the protective frame.

[0053] When the rotating rod 2022 is rotated by the thrust of the push rod 2043, the stabilizing column 2027 will be pushed to move through the cooperation of the slide rail 2025 and the positioning shaft 2026, and the positioning block 2028 will compress the third spring 2029. When the connecting seat 2031 returns to the vertical state and the pressure plate 2041 is separated from the extrusion block 2044, the stabilizing column 2027 can be pushed to move by the third spring 2029, so that the stabilizing column 2027 pushes the rotating rod 2022 to rotate in the opposite direction and reset. At the same time, the rotating rod 2022 will push the push rod 2043 to reset. When the connecting seat 2031 tilts again, the push rod 2043 can be moved again, so that the insulator 102 can always be corrected.

[0054] Specifically, a fixed block 2045 is fixed on one side of the extrusion block 2044, and a fixed column 2046 is fixed at the bottom of the fixed block 2045. The bottom end of the fixed column 2046 is inserted into the support frame 2042 and is movably connected to the support frame 2042. A fourth spring 2047 is fixed at the bottom of the fixed block 2045. When the extrusion block 2044 moves downward, the fourth spring 2047 will be compressed by the fixed block 2045. When the pressure plate 2041 is separated from the extrusion block 2044, the extrusion block 2044 can be pushed upward and reset by the fourth spring 2047. Example 3

[0055] Reference Figure 3 、 Figure 5 、 Figure 8 and Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0056] Specifically, a limiting rod 2017 is fixed to the inner wall of the fixing box 2011, and a limiting groove 2013-1 is provided on the threaded rod 2013. The limiting rod 2017 slides in the limiting groove 2013-1. The two cooperate to limit the threaded rod 2013 to prevent the threaded rod 2013 from rotating with the threaded sleeve 2012. An elastic rod 2018 is fixed to the bottom of the limiting rod 2017. The elastic rod 2018 is inclined, and a positioning groove 2012-1 is provided on the threaded sleeve 2012. There are multiple positioning grooves 2012-1 evenly distributed in an annular shape on the outside of the threaded sleeve 2012. The elastic rod 2018 engages with the positioning groove 2012-1. Through the cooperation of the two, the rotation direction of the threaded sleeve 2012 can be limited so that it can only rotate in the direction of driving the threaded rod 2013 to move upward, and will not rotate in the opposite direction, thereby ensuring stability after adjustment.

[0057] Specifically, a rotating rod 2055 is rotatably connected inside the metal rod 103, and the rotating rod 2055 is rotatably connected to the metal rod 103 through a rotating shaft. One end of the rotating rod 2055 passes through the locking groove 103-1, and the end of the rotating rod 2055 located inside the locking groove 103-1 is L-shaped. The other end of the rotating rod 2055 is located inside the threaded hole, and this end is heavier, so the end located inside the locking groove 103-1 will always be in an upward tilted state, and a groove 2052-1 is provided on the locking block 2052.

[0058] When the metal rod 103 is inserted into the fixed frame 2051 and the locking block 2052 is engaged with the locking groove 103-1, the top of the connecting seat 2031 is connected to the threaded hole. When the top of the connecting seat 2031 moves upward in the threaded hole, it pushes the rotating rod 2055 to rotate upward. At this time, the other end of the rotating rod 2055 rotates downward and engages with the groove 2052-1. Through the cooperation of the two, the locking block 2052 can be locked, so that the locking block 2052 cannot be separated from the locking groove 103-1, thereby further improving the stability of the installation of the insulator 102.

[0059] When in use, when installing the insulator 102, the metal rod 103 is inserted into the fixing frame 2051. When the bottom of the insulator 102 contacts the support plate 2016, the locking block 2052 will engage with the locking groove 103-1. Through the cooperation of the two, the metal rod 103 and the insulator 102 can be locked, so that the insulator 102 can be connected and fixed to the assembly frame 101. At this time, the top of the connecting seat 2031 is connected to the threaded hole. When the top of the connecting seat 2031 moves upward in the threaded hole, it will push the rotating rod 2055 to rotate upward. At this time, the other end of the rotating rod 2055 will rotate downward and engage with the groove 2052-1. Through the cooperation of the two, the locking block 2052 can be locked, so that the locking block 2052 cannot be separated from the locking groove 103-1, thereby further improving the stability of the installation of the insulator 102.

[0060] When the assembly frame 101 rusts due to corrosion from rainwater after long-term use, and deforms due to impact from external forces such as hail, causing the insulator 102 to deviate, the gravity ball 2033 and the positioning seat 2032 will remain stationary, while the connecting seat 2031 will rotate in the positioning seat 2032. The connecting seat 2031 will drive the pressure plate 2041 to squeeze the top inclined surface of the extrusion block 2044, thereby pushing the extrusion block 2044 to move downward, and push the push rod 2043 to move through the inclined surface of the extrusion block 2044, so that the push rod 2043 pushes the rotating rod 2022 to rotate, and then the connecting column 2021 can drive the threaded sleeve 2012 to rotate.

[0061] The threaded sleeve 2012 will drive the threaded rod 2013 to move upward, and the threaded rod 2013 will cooperate with the spherical sleeve 2015 and the spherical seat 2014 to push one side of the support plate 2016 to move upward, and push the porcelain part on the outside of the insulator 102 to rotate upward through the support plate 2016, so that the insulator 102 can be corrected and returned to its normal position. In this way, the contact connection part of the disconnector can be restored to a normal state, ensuring uniform contact pressure and stable contact area, keeping the contact resistance within a normal range, avoiding problems such as heating, oxidation and wear caused by increased contact resistance, and ensuring stable conductive performance of the disconnector.
