Description

Technical Field

[0001] The present invention relates to the technical field of disconnect switches, and particularly to an assembly frame for an outdoor 220KV high-voltage disconnect switch. Background Art

[0002] An outdoor 220KV disconnect switch is a high-voltage switch electrical appliance, mainly used for isolating power sources, switching operations, and maintenance safety measures in the power system. By operating the operating mechanism, the moving contact is separated from or closed with the static contact, thereby realizing the isolation or conduction of the circuit. In the open state, an obvious break is formed between the moving and static contacts, with sufficient insulation distance to reliably isolate the power source and ensure the safety of maintenance personnel and equipment; in the closed state, the moving and static contacts are in close contact, forming a path for the circuit and allowing current to pass through normally. During long-term use of the assembly frame of the outdoor disconnect switch, it will be corroded by rain erosion, which will affect the hardness of the assembly frame. When the assembly frame is impacted by hail or other foreign objects, the assembly frame will be deformed, resulting in the offset of the insulator. The offset of the insulator will cause the moving and static contacts to be unable to be accurately aligned. When closing, good contact cannot be achieved, which will reduce the contact area between the contacts, increase the contact resistance, and easily heat up during operation, accelerating the aging and damage of the contacts. In severe cases, local overheating may occur, melting the metal on the surface of the contacts, further deteriorating the contact condition, and even causing an arc, threatening the safe operation of the equipment.

Specific embodiments

[0028] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. Embodiment 1

[0031] Refer to Figures 3 - 5, which is the first embodiment of the present invention. This embodiment provides an assembly rack for an outdoor 220KV high-voltage disconnector. The assembly rack for the outdoor 220KV high-voltage disconnector includes an assembly rack 101. An insulator 102 is provided on the assembly rack 101. A moving contact is provided at the top of the insulator 102. The number of insulators 102 is multiple, and they are evenly distributed in a straight line on both sides of the top of the assembly rack 101. A movable brake is provided at the top of the insulators 102 on one side. A moving contact is provided on the movable brake. A driving component is provided on the movable brake for driving the movable brake 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. The metal rod 103 is used to fix the insulator 102 on the assembly rack 101. The above are all prior arts and will not be elaborated in this solution. And those skilled in the art can clearly understand the working principle.

[0032] The deviation correction component 200 is provided on the assembly rack 101. The number of the deviation correction components 200 corresponds to that of the insulators 102, and includes an adjusting member 201. The adjusting member 201 includes a fixed box 2011 fixed to the top of the assembly rack 101. A threaded sleeve 2012 is rotatably connected in the fixed box 2011. The threaded sleeve 2012 is rotatably connected to the fixed box 2011 through a bearing. A threaded rod 2013 is threadedly connected in the threaded sleeve 2012. A spherical seat 2014 is fixed to the top end of the threaded rod 2013. A spherical sleeve 2015 is sleeved outside 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.

[0033] A support plate 2016 is fixed to the top of the spherical sleeve 2015. The porcelain part outside the insulator 102 is attached to the top of the support plate 2016. Except for the support plate 2016 and the outside of the fixed box 2011 in the adjusting member 201, the quantity is four, and they are evenly distributed at the four corners inside the fixed box 2011 in a rectangle.

[0034] The assembly rack 101 is made of Q235B steel. After the assembly rack 101 is used for a long time and rusts, when it is hit by hail or foreign objects, the impact force is transmitted to the installation part of the insulator 102 through the cross beam of the assembly rack 101. The deformation is concentrated at the welding part of the assembly rack 101 and the metal rod 103, resulting in plastic deformation in this area. The local concave amount of the cross beam of the deformed assembly rack 10 is ≥1.5mm, and the inclination angle of the metal rod 103 is ≥1.2°, resulting in the offset of the insulator 102 ≥3mm.

[0035] When the assembly frame 101 is deformed, resulting in the offset of the insulator 102, at this time, the threaded sleeve 2012 in the downward offset direction of the insulator 102 will rotate, driving the threaded rod 2013 to move upward. The threaded rod 2013 is matched with the spherical seat 2014 through the spherical sleeve 2015 to push one side of the support plate 2016 upward, and the porcelain part outside the insulator 102 is pushed to rotate upward through the support plate 2016, so as to correct the deviation of the insulator 102 and make the insulator 102 return to the normal position. In this way, the contact connection part of the disconnector can be restored to the normal state, ensuring that the contact pressure is uniform, the contact area is stable, the contact resistance is kept within the normal range, avoiding problems such as heating, oxidation and wear caused by the increase of the contact resistance, and ensuring the stable conductivity of the disconnector.

[0036] The thread pitch of the threaded rod 2013 and the threaded sleeve 2012 is relatively large. Therefore, when the threaded sleeve 2012 rotates at a small angle, the threaded rod 2013 can move a long stroke.

[0037] The connection between the bottom of the insulator 102 and the metal rod 103 is connected through an additional set of spherical sleeves 2015 and spherical seats 2014. This can ensure that when the insulator 102 is pushed by the support plate 2016, it can rotate adaptively without getting stuck. The support plate 2016 can support the insulator 102 to avoid the shaking of the insulator 102 due to the change of the connection method.

[0038] The deviation correction assembly 200 further includes a transmission part 202 and a trigger part 203. The number of the transmission parts 202 corresponds to that of the threaded sleeves 2012. The trigger part 203 includes a connection 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 end of the connection seat 2031 is a threaded column. The connection seat 2031 is fixedly connected to the metal rod 103 by means of threaded locking. A positioning seat 2032 is sleeved outside the connection seat 2031. The positioning seat 2032 is clamped with the outside of the connection seat 2031. The positioning seat 2032 can rotate freely at the bottom of the connection seat 2031 and the two will not separate. A gravity ball 2033 is fixed at the bottom of the positioning seat 2032, and the gravity ball 2033 has a certain weight.

[0039] During the use process, since the positioning seat 2032 can rotate freely at the bottom of the connection seat 2031 and under the influence of the gravity of the gravity ball 2033, the positioning seat 2032 will always maintain a downward vertical state. If the deformation of the assembly frame 101 causes the insulator 102 to tilt, at this time, the gravity ball 2033 and the positioning seat 2032 will remain stationary, while the connection seat 2031 will rotate within the positioning seat 2032 and drive the threaded sleeve 2012 to rotate through the transmission part 202, so as to correct the deviation of the insulator 102. Embodiment 2

[0040] Referring to Figure 3 、 Figure 6 and Figure 7 , this is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] 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 penetrates below the assembly frame 101. The connecting column 2021 is used to drive the threaded sleeve 2012 to rotate. A rotating rod 2022 is sleeved outside the connecting column 2021. An activity groove 2022-1 is opened in the rotating rod 2022. A clamping block 2023 is arranged in the activity groove 2022-1. One side of the clamping block 2023 is inclined. A clamping groove 2021-1 is opened on the connecting column 2021. The clamping block 2023 is engaged with the clamping groove 2021-1. Through the cooperation of the two, the rotating rod 2022 is connected to the connecting column 2021, 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 and resets, the connecting column 2021 will not rotate in the reverse direction, thereby avoiding the situation that the threaded sleeve 2012 rotates in the reverse direction and causes the threaded rod 2013 to move downward.

[0042] The number of the clamping grooves 2021-1 is multiple, and they are evenly distributed in a ring outside the connecting column 2021. Through the arrangement of the multiple clamping grooves 2021-1, the clamping block 2023 can be engaged with the clamping groove 2021-1 at any rotation angle of the rotating rod 2022. A first spring 2024 is fixed on one side of the clamping block 2023. The other end of the first spring 2024 is fixed to the inner wall of the activity groove 2022-1. The first spring 2024 is used to apply a thrust to the clamping block 2023 to make the engagement between the clamping block 2023 and the clamping groove 2021-1 tighter.

[0043] Specifically, the deviation correction assembly 200 further includes a pushing member 204. The pushing member 204 includes a pressing 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. A push rod 2043 is inserted into the support frame 2042. The push rod 2043 is L-shaped and its end contacts the rotating rod 2022. An extrusion block 2044 is inserted into the positioning seat 2032. A slot is opened on the support frame 2042. The extrusion block 2044 is inserted into the slot. 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 keep the same horizontal state as the positioning seat 2032 and will not be offset due to the deformation of the assembly frame 101.

[0044] When the connecting seat 2031 rotates within the positioning seat 2032, since the positioning seat 2032 remains stationary, the connecting seat 2031 drives the pressing plate 2041 to squeeze the top inclined surface of the extrusion block 2044, thereby pushing the extrusion block 2044 downward, and pushing the push rod 2043 to move through the inclined surface of the extrusion block 2044, causing the push rod 2043 to push the rotating rod 2022 to rotate. Furthermore, 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 upward, thereby correcting the deviation of the insulator 102.

[0045] Except for the pressing plate 2041, the number of other components in the pusher 204 is four, which are annularly distributed outside the positioning seat 2032, and the pressing plate 2041 is annular.

[0046] When the assembly frame 101 deforms, it stores elastic potential energy, and thus it can be converted into the kinetic energy of the rotating rod 2022 through the pusher 204. Furthermore, the rotating rod 2022 can drive the connecting column 2021 and the threaded sleeve 2012 to rotate, and complete the adjustment of the inclination angle of the insulator 102.

[0047] When the hail hits multiple times and causes the cumulative deformation of the assembly frame, the gravity ball 2033 always triggers the pusher 204 through the positioning seat 2032, forming a closed-loop mechanism of "deformation - trigger - deviation correction", which can meet the requirements of the service life of outdoor equipment.

[0048] Specifically, the deviation correction assembly 200 further includes a locking member 205. The locking member 205 includes a fixed frame 2051 fixed to the bottom of the assembly frame 101. A locking block 2052 is inserted into the fixed frame 2051. One side of the top of the locking block 2052 is inclined. A locking groove 103-1 is formed 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 be engaged with the locking groove 103-1. Through the cooperation of the two, the metal rod 103 and the insulator 102 can be locked, thereby connecting and fixing the insulator 102 to the assembly frame 101.

[0049] Both the metal rod 103 and the fixed frame 2051 are rectangular. After the metal rod 103 is inserted into the fixed frame 2051, the angle of the insulator 102 can be in an aligned state without adjusting the installation angle of the insulator 102.

[0050] One side of the lock block 2052 is fixed with a mounting block 2053. One side of the mounting block 2053 is fixed with a second spring 2054. The other end of the second spring 2054 is fixed to the fixed frame 2051. The mounting block 2053 is used to support the second spring 2054. A pulling force is applied to the mounting block 2053 through the second spring 2054, and the lock block 2052 is driven to move through the mounting block 2053, so that the lock block 2052 can be more tightly engaged with the lock groove 103-1. A protective frame is fixed to the bottom of the fixed frame 2051.

[0051] Specifically, a slide rail 2025 is fixed to one side of the rotating rod 2022. A positioning shaft 2026 slides in the slide rail 2025. The bottom end of the positioning shaft 2026 is fixed with a stabilizing column 2027. One end of the stabilizing column 2027 is inserted into the protective frame and is movably connected to the inside of the protective frame. A positioning block 2028 is fixed to the outside of the stabilizing column 2027. One side of the positioning block 2028 is fixed with a third spring 2029. The other end of the third spring 2029 is fixed to the inner wall of the protective frame.

[0052] When the rotating rod 2022 rotates under the thrust of the push rod 2043, the stabilizing column 2027 is pushed to move through the cooperation of the slide rail 2025 and the positioning shaft 2026, and the positioning block 2028 compresses the third spring 2029. When the connecting seat 2031 returns to the vertical state and the pressing plate 2041 is separated from the extrusion block 2044, the stabilizing column 2027 can be pushed to move through the third spring 2029, so that the stabilizing column 2027 pushes the rotating rod 2022 to rotate reversely 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.

[0053] Specifically, a fixing block 2045 is fixed to one side of the extrusion block 2044. A fixing column 2046 is fixed to the bottom of the fixing block 2045. The bottom end of the fixing column 2046 is inserted into the support frame 2042 and is movably connected to the inside of the support frame 2042. A fourth spring 2047 is fixed to the bottom of the fixing block 2045. When the extrusion block 2044 moves downward, the fourth spring 2047 will be compressed through the fixing block 2045. When the pressing plate 2041 is separated from the extrusion block 2044, the extrusion block 2044 can be pushed to move upward and reset through the fourth spring 2047. Embodiment 3

[0054] Refer to Figure 3 、 Figure 5 、 Figure 8 and Figure 9 This is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0055] Specifically, a limiting rod 2017 is fixed to the inner wall of the fixed box 2011. 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 along 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. A positioning groove 2012-1 is provided on the threaded sleeve 2012. The number of the positioning grooves 2012-1 is multiple and they are evenly distributed in a ring on the outer side of the threaded sleeve 2012. The elastic rod 2018 is engaged with the positioning groove 2012-1. Through the cooperation of the two, the rotation direction of the threaded sleeve 2012 can be restricted, so that it can only rotate in the direction of driving the threaded rod 2013 to move upward and will not rotate in the reverse direction, thereby ensuring the stability after adjustment.

[0056] Specifically, a rotating rod 2055 is rotatably connected inside the metal rod 103. The rotating rod 2055 is rotatably connected to the inside of the metal rod 103 through a rotating shaft. One end of the rotating rod 2055 penetrates into the locking groove 103-1. One 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 the end part has a heavier weight. Therefore, the end located inside the locking groove 103-1 will always be in an upwardly tilted state. A groove 2052-1 is provided on the locking block 2052.

[0057] 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, at this time, the top end of the connecting seat 2031 is connected to the threaded hole. When the top end 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 be engaged 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 installation stability of the insulator 102.

[0058] During use, when installing the insulator 102, insert the metal rod 103 into the fixed frame 2051. When the bottom of the insulator 102 contacts the support plate 2016, the locking block 2052 will be engaged with the locking groove 103-1. Through the cooperation of the two, the metal rod 103 and the insulator 102 can be locked, thereby connecting and fixing the insulator 102 to the assembly frame 101. At this time, connect the top end of the connecting seat 2031 to the threaded hole. When the top end 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 be engaged 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 installation stability of the insulator 102.

[0059] When the mounting frame 101 is corroded by rainwater and rusted after long-term use, and is deformed due to the impact of external forces such as hail, resulting in the deviation of the insulator 102, at this time, the gravity ball 2033 and the positioning seat 2032 will remain stationary, while the connecting seat 2031 will rotate within the positioning seat 2032. The connecting seat 2031 will drive the pressing plate 2041 to squeeze the top inclined surface of the extrusion block 2044, thereby pushing the extrusion block 2044 to move downward, and pushing the push rod 2043 to move through the inclined surface of the extrusion block 2044, so that the push rod 2043 drives the rotating rod 2022 to rotate, and then the connecting column 2021 can drive the threaded sleeve 2012 to rotate.

[0060] The threaded sleeve 2012 will drive the threaded rod 2013 to move upward. The threaded rod 2013 cooperates with the spherical seat 2014 through the spherical sleeve 2015 to push one side of the support plate 2016 upward, and drives the porcelain part outside the insulator 102 to rotate upward through the support plate 2016, so as to correct the deviation of the insulator 102, make the insulator 102 return to the normal position, so that the contact connection part of the disconnecting switch can return to the normal state, ensure that the contact pressure is uniform and the contact area is stable, keep the contact resistance within the normal range, avoid problems such as heating, oxidation and wear caused by the increase of the contact resistance, and ensure the stable conductivity of the disconnecting switch.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
