Description

Technical Field

[0001] This invention relates to equalizing rings, and more particularly to a multi-layer equalizing ring that is easy to assemble and its assembly method. Background Technology

[0002] In the field of high-voltage testing, equalizing rings are mainly used in gas-insulated switchgear with voltage levels of 220kV and above, high-voltage busbars, and high-voltage switches. During on-site AC withstand voltage tests, equalizing rings can uniformize the electric field strength, improve the electric field distribution, and prevent tip discharge.

[0003] Generally, the equalizing ring is installed on the top of the electrical equipment, 3 to 8 meters above the ground. For such a high installation point, the usual installation method is to use a crane to lift the equipment and have the installers use a bucket truck to assist in the installation.

[0004] However, existing equalizing rings are integrated devices. The higher the electrical equipment is from the ground, the larger the equalizing ring becomes, resulting in a greater overall weight. This leads to time-consuming and labor-intensive installation, affecting testing efficiency and increasing labor intensity. Furthermore, in high-voltage testing, the inconvenient installation hinders rapid response and timely handling during maintenance. Simultaneously, larger equalizing rings require excessive storage space, severely impacting the integration and lightweight development of testing systems and the rapid and safe conduct of field tests. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-layer equalizing ring and its assembly method that are easy to assemble, in order to solve the problems of existing equalizing rings being integrated devices, which result in time-consuming and labor-intensive installation and excessive space occupation.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions: On one hand, a multi-layer pressure equalizing ring that is easy to assemble is provided for installation on a target object. It includes: a first ring body, a second ring body, and a third ring body arranged from top to bottom; a plurality of first connecting members; a plurality of second connecting members; and a plurality of clamping members. The diameter of the second ring body is larger than the diameter of the first ring body, and the diameter of the third ring body is larger than the diameter of the second ring body. An installation assembly is provided on the first ring body for detachable installation on the target object. One end of each of the plurality of first connecting members is tightly connected to the second ring body, and the other end is hung on the first ring body. One end of each of the plurality of second connecting members is tightly connected to the third ring body, and the other end passes through the inner ring of the second ring body and hangs on the first ring body. When the second ring body abuts against the second connecting member and the first connecting member is in a taut state, the clamping members clamp the second connecting member and abut against the second ring body.

[0007] Furthermore, the first connector includes a first connecting rope, a first connecting part disposed at one end of the first connecting rope, and a first hanging part disposed at the other end of the first connecting rope. A plurality of the first connecting ropes are evenly arranged and tightly connected to the second ring body, and a plurality of the first hanging parts are evenly arranged and hung on the first ring body.

[0008] Furthermore, the second connector includes a second connecting rope, a second connecting part disposed at one end of the second connecting rope, and a second hanging part disposed at the other end of the second connecting rope. A plurality of second connecting ropes are evenly arranged and tightly connected to the third ring body, and a plurality of second hanging parts are evenly arranged and hung on the first ring body.

[0009] Furthermore, the length of the second connecting rope is greater than the length of the first connecting rope.

[0010] Furthermore, the mounting assembly includes at least two support members and a sleeve member. One end of the support member is fixedly connected to the first ring body, and the other end is fixedly connected to the sleeve member. The sleeve member is used to be fitted onto the target mounting object.

[0011] Furthermore, the first ring, the second ring, and the third ring are all inflatable airbags, and the surface of the first ring, the second ring, and the third ring is coated with a metal coating.

[0012] Furthermore, both the first connecting rope and the second connecting rope are elastic metal ropes.

[0013] Furthermore, each of the first hanging parts is located between two adjacent second hanging parts, and the contact point between each of the second connecting ropes and the second ring body is located between two adjacent first connecting parts.

[0014] On the other hand, a method for installing a multi-layer equalizing ring, as described above, which is easy to assemble, is provided, comprising: The first ring body is installed on the target installation object using the mounting components; The third ring is hung on the first ring by the second connector; The second ring is fitted over the outside of the second connector from top to bottom along the first ring, and the second ring is hung on the first ring through the first connector; Press the second ring down until it abuts against the second connector and the first connector is taut. Clamp the second connector with the clamping member and abut it against the second ring. Furthermore, a method for disassembling a multi-layer equalizing ring, as described above, is provided, comprising: Remove the clamp from the second connector; Remove the first connector from the first ring body, and remove the second ring body from the bottom up along the first ring body; Remove the second connector from the first ring body and remove the third ring body; Remove the mounting components from the target mounting and remove the first ring body.

[0015] This invention provides a multi-layer equalizing ring and its assembly method for easy assembly, used for installation on a target object.

One end of each of the multiple second connectors is tightly connected to the third ring body, and the other end passes through the inner ring of the second ring body and hangs on the first ring body. When the second ring body abuts against the second connector and the first connector is in a taut state, the corresponding clamping members clamp the second connector and abut against the second ring body. This invention achieves detachable connection between the first ring body, the second ring body, and the third ring body through the first connector and the second connector. Furthermore, the connection between the second ring body and the first ring body, and between the third ring body and the first ring body, is reinforced by the clamping member. When disassembling the equalizing ring, the second ring body can be removed from bottom to top by removing the clamping member, and then the third ring body can be removed. This solves the problem that the existing equalizing ring is an integrated device, which causes time-consuming and labor-intensive installation and occupies too much space.

[0022] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0023] Combination Figure 1-3As shown, the present invention provides a multi-layer pressure equalizing ring that is easy to assemble and is used to install on a target mounting object (not shown). It includes: a first ring body 1, a second ring body 2, and a third ring body 3 arranged from top to bottom; multiple first connectors 4; multiple second connectors 5; and multiple clamping members 6. The diameter of the second ring body 2 is larger than the diameter of the first ring body 1, and the diameter of the third ring body 3 is larger than the diameter of the second ring body 2. An installation assembly 11 is provided on the first ring body 1, and the installation assembly 11 is detachably installed on the target mounting object. One end of each of the multiple first connectors 4 is tightly connected to the second ring body 2, and the other end is hung on the first ring body 1. One end of each of the multiple second connectors 5 is tightly connected to the third ring body 3, and the other end passes through the inner ring of the second ring body 2 and hangs on the first ring body 1. The second connectors 5 are located inside the second ring body 2. When the second ring body 2 abuts against the second connectors 5 and the first connectors 4 are in a taut state, the corresponding clamping members 6 clamp the second connectors 5 and abut against the second ring body 2.

[0024] In this embodiment of the invention, the target installation object, i.e., the installation part on the electrical equipment, is detachably connected to the first ring 1, the second ring 2, and the third ring 3 through the first connector 4 and the second connector 5. The equalizing ring composed of the three rings can more accurately and uniformly control the electric field distribution, eliminate corona discharge and partial discharge to the maximum extent, thereby protecting the equipment insulation, reducing energy loss, reducing electromagnetic interference, and extending the equipment life. Secondly, the diameter of the second ring 2 is larger than the diameter of the first ring 1, and the diameter of the third ring 3 is larger than the diameter of the second ring 2. That is, the first ring 1, the second ring 2, and the third ring 3 are in a stepped shape. The multiple gentle steps can more effectively and evenly and smoothly transition the electric field at high potential to low potential. Multiple rings can be arranged at different heights and radial positions of the electrical equipment, avoiding sudden changes in electric field intensity and minimizing the electric field gradient of the entire area, thereby more effectively suppressing corona discharge and partial discharge.

[0025] Furthermore, when installing the multi-layer equalizing ring, the first ring 1 is first installed on the electrical equipment via the mounting assembly 11. Next, the third ring 3 is hung on the first ring 1. Then, the second ring 2 is fitted over the second connector 5 and hung on the first ring 1. When the second ring 2 abuts against the second connector 5 and the first connector 4 is taut (i.e., the other ends of the first and second connectors 4 and 5 are securely hung on the first ring 1), the second connector 5 is also taut. Both ends of the first and second connectors 4 and 5 are securely hung on the first ring 1. The clamping member 6 clamps the second connector 5 to limit the position of the second ring 2. The mechanism maintains the state of the first connecting piece 4 and the second connecting piece 5, thereby reinforcing the connection between the second ring body 2 and the first ring body 1, and the third ring body 3 and the first ring body 1. This ensures that the second ring body 2 and the third ring body 3 will not fall off during the installation of the multi-layer equalizing ring. When it is necessary to replace, store, or transport the equalizing ring, the multi-layer equalizing ring needs to be disassembled. By removing the clamping piece 6, the second ring body 2 can be removed from bottom to top, followed by the third ring body 3, and then the first ring body 1. The three ring bodies can be transformed from a whole into three independent individuals with different diameters, which can be stacked together for storage. This solves the problem that the existing equalizing ring is an integrated device, which causes time-consuming and labor-intensive installation and excessive space occupation.

[0026] In some embodiments, the first connector 4 includes a first connecting rope 43, a first connecting portion 41 disposed at one end of the first connecting rope 43, and a first hanging portion 42 disposed at the other end of the first connecting rope 43. A plurality of first connecting portions 41 are evenly arranged and tightly connected to the second ring body 2, and a plurality of first hanging portions 42 are evenly arranged and hung on the first ring body 1.

[0027] In this embodiment, the uniform arrangement of the first connecting part 41 and the first hanging part 42 ensures a stable connection between the second ring body 2 and the first ring body 1. Adjusting the angle of the first connecting rope 43 helps the first hanging part 42 to hang on the first ring body 1. The first hanging part 42 hanging on the first ring body 1 helps the second ring body 2 to be quickly installed and removed.

[0028] In some embodiments, the second connector 5 includes a second connecting rope 53, a second connecting portion 51 disposed at one end of the second connecting rope 53, and a second hanging portion 52 disposed at the other end of the second connecting rope 53. The plurality of second connecting portions 51 are evenly arranged and tightly connected to the third ring body 3, and the plurality of second hanging portions 52 are evenly arranged and hung on the first ring body 1.

[0029] In this embodiment, the uniform arrangement of the second connecting part 51 and the second hanging part 52 ensures a stable connection between the third ring body 3 and the first ring body 1. Adjusting the angle of the second connecting rope 53 helps the second hanging part 52 to hang on the first ring body 1, which in turn facilitates the quick installation and removal of the third ring body 3. Specifically, when the second ring body 2 abuts against the second connecting rope 53 and the first connecting member 4 is in a taut state, the corresponding clamping member 6 clamps the second connecting rope 53 and abuts against the second ring body 2.

[0030] In some embodiments, the length of the second connecting rope 53 is greater than the length of the first connecting rope 43.

[0031] In this embodiment, when the third ring 3 is connected to the first ring 1 via the second connecting rope 53, and the second ring 2 is fitted around the outside of the first connecting rope 43 from top to bottom along the first ring 1, the length of the second connecting rope 53 is greater than the length of the first connecting rope 43 when the second ring 2 abuts against the second connecting rope 53, which helps to tighten the first connecting rope 43. Then, the clamping member 6 reinforces the connection between the second ring 2 and the first ring 1, and between the third ring 3 and the first ring 1, ensuring that the second ring 2 and the third ring 3 will not detach from the first ring 1 during the installation of the equalizing ring.

[0032] In some embodiments, the mounting assembly 11 includes at least two supports 111 and a sleeve 112. One end of the support 111 is fixedly connected to the first ring body 1, and the other end is fixedly connected to the sleeve 112. The sleeve 112 is used to be sleeved on the target mounting object.

[0033] In this embodiment, at least two support members 111 can ensure the stable installation of the first ring body 1, and the sleeve member 112 is used to sleeve on the target installation object, thereby installing the first ring body 1 on the electrical equipment.

[0034] In some embodiments, the first ring body 1, the second ring body 2, and the third ring body 3 are all inflatable airbags, and the surface of the first ring body 1, the second ring body 2, and the third ring body 3 are all coated with a metal coating.

[0035] In this embodiment, the traditional equalizing ring is made of a metal skeleton, which is large in size and heavy in weight, making its installation time-consuming and labor-intensive, as well as inconvenient for storage and transportation. The first ring body 1, the second ring body 2, and the third ring body 3 use inflatable air bags, which are extremely lightweight. The metal coating on the surface is usually very thin, and the added weight is negligible. This can significantly reduce the overall weight of the equalizing ring, simplify the installation process, reduce installation costs, and reduce storage space and transportation costs.

[0036] In some embodiments, both the first connecting rope 43 and the second connecting rope 53 are elastic metal ropes.

[0037] In this embodiment, both the first connecting rope 43 and the second connecting rope 53 are elastic metal ropes. The elastic metal ropes ensure the conductivity of the first connecting rope 43 and the second connecting rope 53, which helps to connect the first ring 1, the second ring 2 and the third ring 3 into a stepped shape. The multiple gentle steps can more effectively and evenly and smoothly transition the electric field at the high potential to the low potential. At the same time, the first connecting rope 43 and the second connecting rope 53 are elastic, which helps the second ring 2 to abut against the second connecting rope 53 and helps to tighten the first connecting rope 43, thereby ensuring the stability of the connection between the second ring 2 and the first ring 1, and between the third ring 3 and the first ring 1.

[0038] In some embodiments, each first hanging part 42 is located between two adjacent second hanging parts 52, and the contact point between each second connecting rope 53 and the second ring body 2 is located between two adjacent first connecting parts 41.

[0039] In this embodiment, the first hanging part 42 and the second hanging part 52 are hung on the first ring body 1 at intervals, which avoids interference between the first connecting member 4 and the second connecting member 5. The contact point between the second connecting rope 53 and the second ring body 2 is located between two adjacent first connecting parts 41, which avoids interference between the clamping member 6 and the first connecting part 41, and helps to ensure the smooth connection of the entire multi-layer equalizing ring.

[0040] Combination Figure 4 As shown, the present invention also provides an installation method for a multi-layer equalizing ring that is easy to assemble, including steps S10 to S40: S10. Install the first ring body 1 onto the target installation object using the mounting component 11; S20. The third ring body 3 is hung on the first ring body 1 by the second connector 5; S30. The second ring 2 is fitted onto the outside of the second connector 5 from top to bottom along the first ring 1, and the second ring 2 is hung on the first ring 1 through the first connector 4. S40. Press the second ring 2 down until the second ring 2 abuts against the second connector 5 and the first connector 4 is in a taut state. Place the clamping member 6 against the top of the second ring 2 and clamp the second connector 5.

[0041] In this embodiment of the invention, when installing a multi-layer equalizing ring, the first ring body 1 is first installed on the electrical equipment via the mounting assembly 11. Next, the third ring body 3 is hung on the first ring body 1 via the second connector 5. Then, the second ring body 2 is fitted over the second connector 5 from top to bottom along the first ring body 1. The second ring body 2 is then hung on the first ring body 1 via the first connector 4. When the second ring body 2 abuts against the second connector 5 and the first connector 4 is in a taut state, the second connector 5 is also in a taut state. The other ends of both the first connector 4 and the second connector 5 are securely hung on the first ring body 1. The second ring body 2 is limited by clamping the second connector 5 via the clamping member 6, thereby maintaining the state of the first connector 4 and the second connector 5. This strengthens the connection between the second ring body 2 and the first ring body 1, and between the third ring body 3 and the first ring body 1, ensuring that the second ring body 2 and the third ring body 3 will not fall off during the installation of the equalizing ring.

[0042] Combination Figure 5 As shown, the present invention also provides a method for disassembling a multi-layer equalizing ring that is easy to assemble, including steps S50~S80: S50. Remove the clamping member 6 from the second connecting member 5; S60. Remove the first connector 4 from the first ring body 1, and remove the second ring body 2 from the bottom to the top along the first ring body 1; S70. Remove the second connector 5 from the first ring body 1 and remove the third ring body 3; S80. Remove the mounting component 11 from the target mounting object and remove the first ring body 1.

[0043] In this embodiment of the invention, when it is necessary to replace, store, or transport the equalizing ring, the equalizing ring needs to be disassembled. The clamping piece 6 can be removed to remove the second ring 2 from bottom to top, then the third ring 3, and then the first ring 1. The three rings can be transformed from a whole into three independent individuals, and the three have different diameters, so they can be stacked together for storage. This solves the problem that the existing equalizing ring is an integrated device, which causes time-consuming and laborious installation and occupies too much space.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
