Description

Technical Field

[0001] This application relates to the field of bypass switches, and more specifically to a bypass switch impact buffer protection device. Background Technology

[0002] Existing bypass switches can be referenced. Figure 2 The schematic diagram shows that during the opening process, the bypass switch assembly 10 drives the lever 20 to move, exerting a certain impact force on the auxiliary switch assembly 30, causing the auxiliary switch assembly to operate. Furthermore, during the opening process, the operating mechanism of the bypass switch column assembly deforms due to the significant impact force, causing considerable damage to the bypass switch assembly. Therefore, by improving the structure of the auxiliary switch assembly, the impact force on the operating mechanism of the bypass switch column assembly during the opening process can be buffered, thereby effectively reducing the impact damage to the auxiliary switch assembly and mitigating the rebound phenomenon of the bypass switch assembly's operating mechanism to some extent.

It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0029] refer to Figures 1 to 9 According to a preferred embodiment of the present invention, a bypass switch impact buffer protection device is provided, wherein the structure of the bypass switch impact buffer protection device is as follows: Figure 1As shown, the bypass switch impact buffer protection device includes a bypass switch assembly 10, at least one swing lever 20 and at least one auxiliary switch assembly 30. The swing lever 20 and the auxiliary switch assembly 30 are both disposed on the top of the bypass switch assembly 10, and the swing lever 20 and the auxiliary switch assembly 30 are spaced apart. Preferably, there are two swing levers 20 and two auxiliary switch assemblies 30. It should be noted that the bypass switch assembly 10 includes a liftable limiting plate 11. One end of the swing lever 20 is engaged with one end of the limiting plate 11, and the other end is positioned to abut against the side of the auxiliary switch assembly 30 facing the swing lever 20. It should also be noted that the auxiliary switch includes a limiting block 31, and the end of the swing lever 20 abuts against the limiting block 31. Specifically, when the limiting plate 11 moves upward (i.e., in the open state), the limiting plate 11 drives the swing lever 20 to swing outward, impacting the side wall of the limiting block 31. This application improves the limiting block 31... The structure effectively reduces the impact damage to the auxiliary switch and also alleviates the rebound phenomenon of the operating mechanism of the bypass switch assembly 10 to a certain extent. Specifically, the operating mechanism includes a limiting plate 11, a pull rod 12, and a handle 13. The pull rod 12 is vertically and vertically disposed at the center of the bypass switch assembly 10, and the limiting plate 11 is fixed on the pull rod 12 and moves synchronously with the pull rod 12. One end of the handle 13 is rotatably disposed on the top of the bypass switch assembly 10 and cooperates with the top of the pull rod 12. That is, by operating the handle 13, the limiting plate 11 can be raised or lowered by a predetermined distance.

[0030] It should also be noted that the swing lever 20 has an insertion part 21, a rotating part 22, and a stop part 23. The insertion part 21, the rotating part 22, and the stop part 23 together form an arc-shaped structure. The rotating part 22 is rotatably disposed on the top of the bypass switch assembly 10. That is, when the limiting plate 11 moves downward, the limiting plate 11 will press down on the insertion part 21, so that the stop part 23 swings upward. Conversely, when the limiting plate 11 moves upward, the limiting plate 11 will pull up the insertion part 21, so that the stop part 23 swings downward, so that the insertion part 21 abuts against the surface of the limiting block 31.

[0031] It should be noted that the structure of the limiting block 31 is as follows: Figure 6As shown, the top of the limiting block 31 has at least one first mounting hole 3101, and the bottom of the limiting block 31 has at least one buffer groove 3102. The buffer groove 3102 corresponds one-to-one with the first mounting hole 3101, and preferably there are two first mounting holes 3101 and two buffer grooves 3102. The auxiliary switch assembly 30 further includes at least one insertion rod 32. One end of the insertion rod 32 passes through the first mounting hole 3101 and the buffer groove 3102 in sequence and is placed on the outside, while the other end of the insertion rod 32 abuts against the top of the limiting block 31. The auxiliary switch assembly 30 also includes at least one connector 33. One end of the connector 33 is installed on the top of the bypass switch assembly 10, and the other end cooperates with the end of the externally placed insertion rod 32 to define the position of the insertion rod 32.

[0032] Specifically, the auxiliary switch assembly 30 further includes a limit switch 34 and an insulating plate 35. The limit switch 34 is disposed within the limiting block 31, and the insertion rod 32 also passes through the limit switch 34. In addition, the insulating plate 35 is also disposed within the limiting block 31 and placed on top of the limit switch 34, and the insertion rod 32 also passes through the insulating plate 35.

[0033] It should be noted that the limiting block 31 is a concave connector 33. The limiting block 31 has a first connecting wall 311, a second connecting wall 312 and a third connecting wall 313. The first connecting wall 311 and the third connecting wall 313 are arranged vertically, and the two ends of the second connecting wall 312 are respectively connected to the ends of the first connecting wall 311 and the second connecting wall 312. That is, the first connecting wall 311, the second connecting wall 312 and the third connecting wall 313 are integrally formed, and the first mounting hole 3101 is located in the first connecting wall 311, and the buffer groove 3102 is located in the third connecting wall 313. The first connecting wall 311, the second connecting wall 312, and the third connecting wall 313 together form a concave cavity. The limit switch 34 and the insulating plate 35 are both disposed in the concave cavity. In addition, the surface of the second connecting wall 312 has a groove 3103. The upper and lower ends of the groove 3103 are connected to the outside. The groove 3103 is also connected to the concave cavity. The abutting part 23 of the swing lever 20 is configured to abut against the second connecting wall 312 and face the groove 3103.

[0034] It should be noted that the structural design of the buffer groove 3102 can reduce the impact of the swing lever 20 on the auxiliary switch assembly 30. Specifically, the buffer groove 3102 allows the limiting block 31 to have a certain displacement, thereby buffering the impact force of the operating mechanism during the tripping process. Specifically, the first embodiment of the buffer groove 3102 is as follows: Figure 6-7 The buffer groove 3102 has a second mounting hole 31021 and a third mounting hole 31022. The second mounting hole 31021 is directly opposite the first mounting hole 3101, that is, the axis of the second mounting hole 31021 and the axis of the first mounting hole 3101 are both on the same straight line. The third mounting hole 31022 is located on one side of the second mounting hole 31021 and communicates with the second mounting hole 31021. The tops of the second mounting hole 31021 and the third mounting hole 31022 together form an 8-shape. The bottoms of the second mounting hole 31021 and the third mounting hole 31022 together form an ellipse. The third mounting hole 31022 is an oblique hole, such that the wall surface of the insertion rod 32 located within the second mounting hole 31021 is spaced a predetermined distance from the wall surface forming the second mounting hole 31021. This arrangement of the third mounting hole 31022 provides space for the offset of the limit block 31 when the swing lever 20 subsequently impacts the limit block 31, thus achieving buffer protection by cutting off the insertion rod 32. Specifically, the specific formation or structure of the buffer groove 3102 is not limited, such as... Figure 8 As shown, specifically, the wall surface forming the buffer groove 3102 has an abutment surface 31023, and the surface of the insertion rod 32 can abut against the abutment surface 31023 to define the position of the insertion rod 32. The surface of the insertion rod 32, positioned in the buffer groove 3102 and away from the abutment surface 31023, is spaced a predetermined distance from the wall surface forming the buffer groove 3102 and away from the abutment surface 31023 to form a clearance cavity 31024. The clearance cavity 31024 is an inclined cavity. Specifically, the wall surface forming the clearance cavity 31024 forms an angle α with the third connecting wall 313, where the angle α is preferably 10-90 degrees. Furthermore, the bottom wall of the buffer groove 3102 also has an arc-shaped chamfer 31025, which is located below the abutment surface 31023.
