TECHNICAL FIELD

[0001] The utility model relates to isolating switch equipment technical field, concretely relates to a connection structure of rotating flange and rotating insulator flange for isolating switch. BACKGROUND

[0002] In modern power system, the substation as the key hub of power transmission and distribution, its safe and stable operation is very important. Isolating switch as indispensable electrical primary equipment in substation, it is mainly used for isolating power supply when electrical equipment overhauls, forms obvious disconnecting point, to ensure the safety of the maintenance personnel.

[0003] In prior art, for part of the isolating switch conductive base, a relatively simple connection mode is adopted between the rotating flange and the rotating insulator flange, that is, four screw rods are connected, and the insulating rod (insulator) drives the rotating flange of isolating switch to rotate through screw rod, to realize the switching operation of switch, complete the isolation and conduction control of circuit.

[0004] However, in actual operation process, the above existing connection structure exposes a big hidden danger. In the rotating process of isolating switch, due to the force transmission mode and structural characteristics, four screw rods need to bear huge shearing force. Under the action of this high shearing force for a long time, the screw rod is easy to appear skew, deformation and even breakage, and then directly affect the normal rotation of isolating switch, lead to isolating switch unable to operate according to the expected, seriously threaten the safe and stable operation of power system.

[0005] Therefore, how to solve the problem of the above existing technology that the screw rod is easy to deform, becomes the subject to be studied and solved by the utility model. UTILITY MODEL CONTENT

[0006] The utility model aims at providing a connection structure of rotating flange and rotating insulator flange for isolating switch.

[0007] In order to achieve the above object, the utility model adopts the following technical scheme:

[0008] A connection structure of rotating flange and rotating insulator flange for isolating switch, for connecting rotating flange and rotating insulator flange, the connection structure includes first connecting assembly, second connecting assembly, third connecting assembly and fourth connecting assembly;

[0009] The first connecting assembly is used as the mechanism for being detachably connected with the rotating flange;

[0010] The second connecting assembly is used as the mechanism for being detachably connected with the rotating insulator flange;

[0011] The third connecting assembly is connected to the first connecting assembly;

[0012] The fourth connecting assembly is connected to the second connecting assembly and serves as a mechanism for detachable connection with the third connecting assembly;

[0013] The third connecting assembly comprises a first connecting plate and at least one first connecting nut, the first connecting plate is connected to the first connecting assembly, the first connecting plate is provided with first through holes, and the number of the first through holes is the same as that of the first connecting nut;

[0014] The fourth connecting assembly comprises a second connecting plate and at least one second connecting nut, the second connecting plate is connected to the second connecting assembly, the second connecting plate is provided with second through holes, and the number of the second through holes, the number of the second connecting nut and the number of the first through holes are the same;

[0015] At least one of the third connecting assembly and the fourth connecting assembly comprises at least one connecting screw, and the number of the connecting screw is the same as that of the second through holes.

[0016] In the above scheme, the connection mode of the rotating flange and the rotating insulator flange in the disconnecting switch is redesigned. Compared with the existing screw, the contact area of the first connecting plate with the first connecting assembly is larger, and the force can be more evenly distributed on the first connecting plate, avoiding the force concentrated on a few points, greatly reducing the shear force borne by the local part, thereby reducing the possibility of damage due to excessive local stress, realizing reliable connection of the rotating flange and the rotating insulator flange in the disconnecting switch, ensuring reliable operation of the disconnecting switch, and reducing the probability of failure of related equipment.

[0017] Further technical solutions, the connecting structure is configured to have a connection state:

[0018] In the connection state, the first connecting assembly is detachably connected with the rotating flange, the second connecting assembly is detachably connected with the rotating insulator flange, the connecting screw passes through the first through hole and the second through hole, and the first connecting nut and the second connecting nut are threadedly connected with the connecting screw to realize detachable connection of the first connecting plate and the second connecting plate.

[0019] Through the arrangement of this part, the reliable connection of the first connecting plate and the second connecting plate is stably realized, and the separation of the two is facilitated.

[0020] Further technical solutions, the first connecting plate is connected to the central part of the first connecting assembly, and / or the second connecting plate is connected to the central part of the second connecting assembly.

[0021] With the first connecting plate connected to the center part of the first connecting assembly as an example, by defining the connecting area, the force can be more evenly transmitted from the connecting plate to the first connecting assembly, avoiding the situation that the local force is too large, thereby reducing the stress concentration phenomenon and improving the carrying capacity of the first connecting assembly.

[0022] Further, the first through hole is arranged along the thickness direction of the first connecting plate, and the second through hole is arranged along the thickness direction of the second connecting plate.

[0023] In the connected state, the thickness direction of the first connecting plate is parallel to the thickness direction of the second connecting plate.

[0024] Through the arrangement of this part, the first connecting plate and the second connecting plate can better share the external force and improve the carrying capacity of both.

[0025] Further, in the connected state, in the thickness direction of the first connecting plate, the area of the part where the projection of the first connecting plate and the projection of the second connecting plate overlap each other is A, the area of the part of the projection of the first connecting plate that does not overlap with the projection of the second connecting plate is B, and the area of the part of the projection of the second connecting plate that does not overlap with the projection of the first connecting plate is C.

[0026] A and B satisfy: A > B;

[0027] A and C satisfy: A > C.

[0028] Through the arrangement of this part, the first connecting plate and the second connecting plate can better share the external force and ensure that both have sufficient carrying capacity.

[0029] Further, the first through hole and the second through hole are both long circular holes, and the extension direction of the long circular hole is parallel to the direction from the rotating flange to the rotating insulator flange.

[0030] The long circular hole can provide a larger connection margin. Taking the rotating flange and the rotating insulator flange as an example, it is suitable for different distances between the two, improves the application scope of the application, and improves the practicality of the application.

[0031] Further, the first connecting assembly includes a first connecting flange and a first threaded connecting structure, the first connecting flange is detachably connected to the rotating flange through the first threaded connecting structure, and a third through hole is arranged on the first connecting flange corresponding to the first threaded connecting structure.

[0032] The second connecting assembly comprises a second connecting flange and a second threaded connecting structure, the second connecting flange is detachably connected with the rotating insulator flange through the second threaded connecting structure, and a fourth through hole is arranged on the second connecting flange and corresponds to the second threaded connecting structure.

[0033] Taking the first connecting assembly as an example, the detachable connection between the first connecting assembly and the rotating flange is realized by the above arrangement, which is convenient, fast and simple in structure.

[0034] Further, the third through hole and the fourth through hole are both long circular holes, and the extension direction of the long circular hole is parallel to the horizontal direction.

[0035] In this part, the arrangement of the long circular hole has the same effect as the above arrangement of the long circular hole, further improves the application range of the application, and further improves the practicability of the application.

[0056] The third connecting assembly 5 comprises a first connecting plate 51 and at least one first connecting nut 52, the first connecting plate 51 is connected to the first connecting assembly 3, the first connecting plate 51 is provided with a first through hole 511, the number of the first through hole 511 is the same as that of the first connecting nut 52;

[0057] The fourth connecting assembly 6 comprises a second connecting plate 61 and at least one second connecting nut 62, the second connecting plate 61 is connected to the second connecting assembly 4, the second connecting plate 61 is provided with a second through hole 611, the number of the second through hole 611, the number of the second connecting nut 62 and the number of the first through hole 511 are the same;

[0058] At least one of the third connecting assembly 5 and the fourth connecting assembly 6 comprises at least one connecting screw 7, the number of the connecting screw 7 is the same as that of the second through hole 611.

[0059] In some embodiments, the first connecting plate 51 is fixedly connected with the first connecting assembly 3, and the second connecting plate 61 is fixedly connected with the second connecting assembly 4, so as to improve the connection strength.

[0060] Rotary flange 1 is installed on conductive base 8, and rotary insulator flange 2 is installed on rotary insulator 9.

[0061] In some embodiments, the first connecting plate 51 and the second connecting plate 61 have the same structure.

[0062] The first connecting component 3 and the second connecting component 4 are described in detail in the following embodiments, and will not be elaborated here. The focus of this application is on the third connecting component 5 and the fourth connecting component 6.

[0063] In some embodiments, taking the third connecting component 5 as an example, the two can be connected by a fixed method such as welding, or by a detachable method such as threaded connection. Compared with the threaded connection method in the prior art, the connection method is more diversified and can be flexibly selected according to requirements.

[0064] This application essentially replaces the existing screw with the third connecting component 5 and the fourth connecting component 6. Specifically, the existing screw is replaced by the first connecting plate 51 and the second connecting plate 61, while the connecting screw 7 and other structures serve as components connecting the first connecting plate 51 and the second connecting plate 61. The effects are as follows: The connection method of the rotating flange 1 and the rotating insulator flange 2 in the disconnecting switch has been redesigned. Compared with the existing screw, taking the first connecting plate 51 as an example, the contact area between the first connecting plate 51 and the first connecting component 3 is larger, which can distribute the force more evenly on the first connecting plate 51, avoiding the force concentration on a few points, greatly reducing the shear force borne locally, thereby reducing the possibility of damage due to excessive local force, realizing a reliable connection between the rotating flange 1 and the rotating insulator flange 2 in the disconnecting switch, ensuring reliable operation of the disconnecting switch, and reducing the probability of related equipment failure.

[0065] It should be emphasized that this application provides two connecting plates, which has additional effects on improving the applicability and practicality compared to providing only a single connecting plate. For details, please refer to the description of the elongated hole in the following embodiments.

[0066] See Figure 2 In this embodiment, the connection structure is configured to have a connected state:

[0067] In the connected state, the first connecting component 3 is detachably connected to the rotary flange 1, the second connecting component 4 is detachably connected to the rotary insulator flange 2, the connecting screw 7 passes through the first through hole 511 and the second through hole 611, and the first connecting nut 52 and the second connecting nut 62 are threadedly connected to the connecting screw 7 to realize the detachable connection between the first connecting plate 51 and the second connecting plate 61.

[0068] In some embodiments, multiple connecting screws 7 are provided, and each connecting screw 7 is respectively provided with a first through hole 511 and a second through hole 611. Each first connecting nut 52 and each second connecting nut 62 are respectively threadedly connected to each connecting screw 7 to realize the detachable connection between the first connecting plate 51 and the second connecting plate 61.

[0069] For ease of understanding, the following description uses a single first through hole 511, a single second through hole 611, a single connecting screw 7, a single first connecting nut 52, and a single second connecting nut 62. The connecting screw 7 passes through the first through hole 511 and the second through hole 611. One end of the connecting screw 7 is located on the side of the first connecting plate 51 away from the second connecting plate 61 and is threadedly connected to the first connecting nut 52. The other end is located on the side of the second connecting plate 61 away from the first connecting plate 51 and is threadedly connected to the second connecting nut 62. The first connecting nut 52 and the second connecting nut 62 clamp and fix the first connecting plate 51 and the second connecting plate 61, thereby achieving a detachable connection between the first connecting plate 51 and the second connecting plate 61.

[0070] The configuration in this embodiment ensures a stable and reliable connection between the first connecting plate 51 and the second connecting plate 61, while also facilitating their separation.

[0071] See Figure 4 , Figure 5 In this embodiment, the first connecting plate 51 is connected to the central portion of the first connecting component 3, and / or the second connecting plate 61 is connected to the central portion of the second connecting component 4.

[0072] For ease of understanding, the first connecting plate 51 is described here as a square plate and the first connecting component 3 is a cylindrical structure, with the axis of the first connecting plate 51 coinciding with the axis of the first connecting component 3.

[0073] In some embodiments, the first connecting plate 51 is connected to the central portion of the first connecting component 3, and the second connecting plate 61 is connected to the portion near the central portion of the second connecting component 4.

[0074] Taking the first connecting plate 51 connected to the center part of the first connecting component 3 as an example, by limiting the connection area, the force can be transmitted from the connecting plate to the first connecting component 3 more evenly, avoiding excessive local stress, thereby reducing stress concentration and improving the load-bearing capacity of the first connecting component 3.

[0075] See Figure 2 , Figure 4 and Figure 5In this embodiment, the first through hole 511 passes through the first connecting plate 51 along the thickness direction of the first connecting plate 51, and the second through hole 611 passes through the second connecting plate 61 along the thickness direction of the second connecting plate 61.

[0076] In the connected state, the thickness direction of the first connecting plate 51 is parallel to the thickness direction of the second connecting plate 61.

[0077] The purpose of this embodiment can be seen as limiting the connection to ensure that the surface with the largest area on the first connecting plate 51 and the surface with the largest area on the second connecting plate 61 are closely fitted in the connected state.

[0078] Through the configuration of this embodiment, the first connecting plate 51 and the second connecting plate 61 can better distribute external forces and improve their load-bearing capacity.

[0079] See Figure 2 In this embodiment, in the connected state, in the thickness direction of the first connecting plate 51, the area of ​​the portion where the projection of the first connecting plate 51 and the projection of the second connecting plate 61 overlap is set as A, the area of ​​the portion of the projection of the first connecting plate 51 that does not overlap with the projection of the second connecting plate 61 is set as B, and the area of ​​the portion of the projection of the second connecting plate 61 that does not overlap with the projection of the first connecting plate 51 is set as C.

[0080] A and B satisfy the condition: A>B;

[0081] The condition A and the condition C satisfy: A > C.

[0082] The purpose of this embodiment can be seen as limiting the area of ​​the region where the largest surface area on the first connecting plate 51 and the largest surface area on the second connecting plate 61 are closely attached in the connected state.

[0083] The configuration of this embodiment enables the first connecting plate 51 and the second connecting plate 61 to better distribute external forces, ensuring that both have sufficient load-bearing capacity.

[0084] In some embodiments, B and C may be set to zero or approximately zero.

[0085] To avoid misunderstanding, it is emphasized here that the explanation is based on the first connecting plate 51, and the area of ​​the part of the projection of the first connecting plate 51 that overlaps with the projection of the second connecting plate 61 is set as A.

[0086] See Figure 4 , Figure 5 In this embodiment, both the first through hole 511 and the second through hole 611 are elongated holes, and the extension direction of the elongated holes is parallel to the direction along the rotating flange 1 to the rotating insulator flange 2.

[0087] by Figure 2 With the orientation of the central structure as a reference, the first perforation 511 and the second perforation 611 can be considered to extend vertically.

[0088] The elongated hole can provide a larger connection margin, as illustrated by the rotary flange 1 and the rotary insulator flange 2, which are suitable for situations where the spacing between the two is different, thereby improving the applicability and practicality of this application.

[0089] See Figure 2 , Figure 3 In this embodiment, the first connecting assembly 3 includes a first connecting flange 31 and a first threaded connection structure 32. The first connecting flange 31 is detachably connected to the rotary flange 1 through the first threaded connection structure 32. A third through hole 311 is provided on the first connecting flange 31 corresponding to the first threaded connection structure 32.

[0090] The second connecting assembly 4 includes a second connecting flange 41 and a second threaded connection structure 42. The second connecting flange 41 is detachably connected to the rotating insulator flange 2 through the second threaded connection structure 42. A fourth through hole 411 is provided on the second connecting flange 41 corresponding to the second threaded connection structure 42.

[0091] It should be noted that, taking the first connecting component 3 as an example, the flange structure (first connecting flange 31) and the threaded connection structure (first threaded connection structure 32) are both existing technologies, and the specific implementation method can also refer to the above-mentioned method of connecting the first connecting plate 51 and the second connecting plate 61.

[0092] Taking the first connecting component 3 as an example, this embodiment uses the above-mentioned settings to achieve a detachable connection between the first connecting component 3 and the rotating flange 1, which is convenient, quick and simple in structure.

[0093] See Figure 4 , Figure 5 In this embodiment, both the third perforation 311 and the fourth perforation 411 are elongated holes, and the extension direction of the elongated holes is parallel to the horizontal direction.

[0094] It should be noted that the above horizontal direction is based on... Figure 2 Figure 2 Figure 3 Figure 4 Figure 5 Figure 2 The explanation is based on the orientation of the central structure. To make it clearer, it is further explained that the extension directions of the third perforation 311 and the fourth perforation 411 are perpendicular to the extension direction of the first perforation 511.

[0095] The oblong hole in this embodiment has the same effect as the oblong hole described above, further improving the applicability and practicality of this application.

[0096] In this embodiment, the oblong hole is suitable for different first threaded connection structures 32 and different second threaded connection structures 42.

[0097] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
