Description

Technical Field

[0001] This invention relates to the field of disconnecting switch technology, and more specifically to a disconnecting switch and its operating mechanism. Background Technology

[0002] Disconnect switches are used to open or close circuits, and feature rapid opening or closing to minimize the impact of electric arcs. These switching devices are typically constructed so that an operator manually or with other tools operates a lever to actuate a series of linked components, causing the moving contact to open or close the stationary contact. When disconnected, a disconnect switch isolates non-energized parts from energized parts, creating a clear break point to isolate faulty equipment or equipment undergoing power outage maintenance. During power outage maintenance of electrical equipment, isolating the equipment from the power supply prevents safety accidents. Disconnect switches are widely used in power distribution and automation systems in construction, power, petrochemical, and other industries. Common rotary disconnect switches include an operating mechanism and a contact system, with the contact system consisting of a moving contact and a stationary contact. The operating mechanism of the disconnect switch moves the moving contact through the rotation of a rotating element, thereby opening or closing it with the stationary contact. Currently, the operating mechanisms of disconnect switches are complex and space-consuming, hindering product miniaturization. Summary of the Invention

[0003] Therefore, in response to at least one of the above problems, the present invention provides a disconnecting switch and its operating mechanism.

[0004] This invention is implemented using the following scheme:

[0005] This invention proposes an operating mechanism for a disconnecting switch, comprising a base and a linkage component. The linkage component is rotatably disposed within the base. The rotation of the linkage component actuates the contact system of the disconnecting switch to achieve opening and closing. A connecting rod and an energy storage element are connected between the linkage component and the base. The rotation of the linkage component actuates the energy storage element to store energy. The connecting rod is used to guide and limit the energy storage element. One end of the connecting rod is hinged and positioned relative to the base, while the other end of the connecting rod is rotatably and slidably connected to the linkage component.

[0006] In one embodiment, the linkage member is provided with a pivot shaft, and one end of the connecting rod is provided with a groove, in which the pivot shaft of the linkage member passes through the groove, so that one end of the connecting rod is rotatably and slidably connected to the linkage member.

[0007] In one embodiment, the energy storage element is directly or by means of an accessory fitted onto the connecting rod.

[0008] In one embodiment, the energy storage element is a compression spring, which is directly sleeved on the connecting rod; at least a portion of the length of the groove on the connecting rod covers the energy storage compression stroke of the compression spring.

[0009] In one embodiment, one end of the connecting rod is hinged to the base by a pin, and two sliding sleeves are fitted on the pin. One end of the compression spring abuts against the pin through the sliding sleeves, and the other end of the compression spring abuts against the pivot shaft.

[0010] In one embodiment, the system further includes a main shaft and a first gear and a second gear that mesh with each other. The first gear is coaxially connected to one end of the main shaft, and the second gear and the linkage component are engaged through a mating structure to achieve synchronous rotation. The linkage component is provided with a first cylindrical structure, which has a first connecting structure. The second gear is provided with a second cylindrical structure, which has a second connecting structure. The first connecting structure and the second connecting structure are a set of mating cylinders and mating holes that can be mated with each other. The first cylindrical structure and / or the second cylindrical structure serve as the pivot shaft.

[0011] In one embodiment, the system further includes a main shaft and a first gear and a second gear that mesh with each other. The first gear is coaxially connected to one end of the main shaft. The second gear and the linkage component are mated together by an interlocking structure to achieve synchronous rotation. The linkage component is provided with a first cylindrical structure, which has a first connecting structure. The second gear is provided with a second cylindrical structure, which has a second connecting structure. The first connecting structure and the second connecting structure are a set of mating cylinders and mating holes that can be interlocked. The depth of the mating hole is less than the length of the mating cylinder, so there is an assembly gap between the first cylindrical structure and the second cylindrical structure. The width of the assembly gap is slightly greater than the thickness of the connecting rod, so that the mating cylinder passes through the groove and serves as the pivot shaft.

[0012] In one embodiment, the axis of the first gear and the axis of the second gear are perpendicular to each other.

[0013] In one embodiment, the energy storage element and the connecting rod constitute an energy storage assembly. The energy storage assembly is provided with two sets and is symmetrically arranged around the rotation axis of the linkage member. The linkage member is provided with two pivot shafts, which respectively cooperate with the two sets of the energy storage assemblies.

[0014] In one embodiment, the system further includes a main shaft, which is connected to the linkage component and can drive the linkage component to rotate. The main shaft includes a first shaft segment and a second shaft segment, which are intermittently connected by transmission.

[0015] In one embodiment, a first transmission structure is provided at one end of the first shaft segment, and a second transmission structure is provided at one end of the second shaft segment. The first transmission structure and the second transmission structure are a set of shafts with keyed teeth and shaft holes with keyways that can cooperate with each other for transmission. The central angle corresponding to the keyway is greater than the central angle corresponding to the keyed teeth, thereby realizing an intermittent transmission connection between the first shaft segment and the second shaft segment.

[0016] The present invention also proposes a disconnecting switch, characterized in that it includes a disconnecting switch operating mechanism as described in any of the preceding claims.

[0017] The technical solution provided by this invention has the following technical effects:

[0018] This invention provides an operating mechanism for a disconnecting switch, including a base, a main shaft, and a linkage component. The main shaft is driven by the linkage component and can rotate the linkage component. The rotation of the linkage component actuates the contact system of the disconnecting switch to achieve opening and closing. The rotation of the linkage component can compress the energy storage element for energy storage. A connecting rod is used to guide and limit the energy storage element. One end of the connecting rod is hinged to the base, and the other end of the connecting rod is rotatably and slidably connected to the linkage component. Compared with a connecting rod that is rotatably and slidably connected to the base, in this invention, the connecting rod is rotatably and slidably connected to the linkage component. Thus, the pushing of the linkage component causes one end of the connecting rod to protrude into the linkage component, resulting in a smaller base volume and a more compact product. Furthermore, this invention has a simple structure, is easy to manufacture, and can reduce costs. Attached Figure Description

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] like Figure 1-7 As shown, this embodiment provides a disconnector switch operating mechanism 1, including a base 10, a main shaft 70, a first gear 80, a second gear 20, an energy storage element 30, a pin 40, a connecting rod 50, and a linkage component 60.

[0030] The first gear 80 is coaxially connected to one end of the main shaft 70, which is used to transmit rotational motion, such as the rotational motion of a handle. This rotational motion, after transmission, actuates the contact system to achieve opening and closing of the circuit breaker. Specifically, the axis of the main shaft 70 is perpendicular to the axis of the second gear 20. The first gear 80 includes a first bevel gear structure 81, and the second gear 20 includes a second bevel gear structure 21. The bevel gear structures of the first gear 80 and the second gear 20 cooperate with each other to achieve vertical power transmission.

[0031] Reference Figure 6 The second gear 20 and the linkage component 60 are rotatably mounted within the base 10. The second gear 20 and the linkage component 60 are engaged through an interlocking structure to achieve synchronous rotation. The linkage component 60 is provided with a first cylindrical structure 61, and the first cylindrical structure 61 is provided with a first connecting structure 611. The second gear 20 is provided with a second cylindrical structure 22, and the second cylindrical structure 22 is provided with a second connecting structure 221. The first connecting structure 611 and the second connecting structure 221 are a set of cylinders and holes that can be interlocked, thereby realizing the interlocking engagement of the second gear 20 and the linkage component 60.

[0032] In this embodiment, the first cylindrical structure 61 is provided with a docking cylinder 611, and the second cylindrical structure 22 is provided with a docking hole 221. The docking cylinder 611 can be inserted and mated with the docking hole 221.

[0033] The linkage component 60 drives the actuation mechanism of the contact system. The rotation of the main shaft 70 realizes the rotation of the linkage component 60, and the rotation of the linkage component 60 is used to actuate the contact system to realize the opening and closing of the circuit breaker.

[0034] This embodiment illustrates power transmission vertically by aligning the axis of the main shaft 70 with the axis of the second gear 20. In other embodiments, depending on the specific rotational transmission direction, the axis of the main shaft 70 may be parallel to the axis of the second gear 20, or at a certain angle, which also achieves power transmission; alternatively, the main shaft 70 may be directly linked to the linkage component 60, which is also a feasible technical solution.

[0035] The energy storage element 30 can be a compression spring, a tension spring, or other energy storage elements, such as a gas spring. This embodiment uses a compression spring as an example. The rotation of the linkage member 60 can actuate the energy storage element 30 to store energy. In this embodiment, the rotation of the linkage member 60 can compress the compression spring to store energy. The energy storage element 30 is sleeved on the connecting rod 50, which is used to guide and limit the energy storage element 30 during compression storage or release. One end of the connecting rod 50 is hinged and positioned relative to the base 10. For example, one end of the connecting rod 50 is hinged to the base 10 via a pin 40, thereby one end of the connecting rod 50 is hinged and positioned relative to the base 10. The other end of the connecting rod 50 is provided with a groove 51, and the mating cylinder 611 of the linkage member 60 passes through the groove 51, so that the other end of the connecting rod 50 is rotatably and slidably connected to the linkage member 60. The energy storage element 30 has its two ends abutting against the pin 40 and the first cylindrical structure 61 and / or the second cylindrical structure 22, respectively. Alternatively, the connecting rod 50 can guide and limit the energy storage element 30 in other ways, such as by providing a guide groove on the connecting rod 50, through which the energy storage element 30 is guided and limited. In this embodiment, the energy storage element 30 is sleeved on the connecting rod 50, thereby allowing the connecting rod 50 to guide and limit the energy storage element 30 during energy storage or release, resulting in a simpler structure.

[0036] Of course, in some other embodiments, when the energy storage element 30 is a gas spring, the gas spring can be fitted onto the connecting rod 50 by means of an accessory, for example, the gas spring can be fitted onto the connecting rod 50 by means of an additional sleeve.

[0037] When the energy storage element 30 is a tension spring, the tension spring is configured to have an orientation opposite to that of the compression spring in this embodiment, so that the rotation of the linkage member 60 can pull the tension spring to store energy.

[0038] In other embodiments, the groove 51 of the connecting rod 50 can also be provided at the opposite end to this solution. That is, one end of the connecting rod 50 can be hinged to the linkage member 60, and the other end of the connecting rod 50 can be provided with the groove 51 and slidably connected to the pin 40. This is also a feasible technical solution. However, in this solution, the end of the connecting rod 50 with the groove 51 may protrude outward from the base 10 due to the pushing of the linkage member 60, resulting in the base 10 needing to have a larger volume, which is not conducive to the miniaturization of the product. That is, compared with the rotatable and slidable connection between the connecting rod 50 and the base 10, in this embodiment, the connecting rod 50 and the linkage member 60 are rotatable and slidable. Thus, the pushing of the linkage member 60 causes the end of the connecting rod 50 with the groove 51 to protrude inward from the linkage member 60, so the base 10 has a smaller volume, the product is more compact, and this solution has a simple structure, is easy to manufacture, and can reduce costs.

[0039] In this embodiment, two sliding sleeves 41 are fitted onto the pin 40, so that one end of the energy storage element 30 does not directly abut against the pin 40, but rather one end of the energy storage element 30 abuts against the sliding sleeve 41. This reduces wear on the pin 40 and makes the operation of the energy storage element 30 more flexible. In other embodiments, the first cylindrical structure 61 and the second cylindrical structure 22 can be replaced with columnar structures with non-cylindrical outer surfaces, such as columnar structures with polygonal outer surfaces. However, in this embodiment, using a cylindrical structure further enhances the flexibility of the operation of the energy storage element 30.

[0040] The depth of the mating circular hole 221 is less than the length of the mating cylinder 611, thus providing an assembly gap between the first cylindrical structure 61 and the second cylindrical structure 22. The width of this assembly gap is slightly greater than the thickness of the connecting rod 50, thereby enabling the mating cylinder 611 of the linkage component 60 to pass through the groove 51. The connecting rod 50 is positioned in the gap between the first cylindrical structure 61 and the second cylindrical structure 22 in the thickness direction, which is beneficial to the stability of the connecting rod 50 and can guide the movement of the connecting rod 50. Of course, in other embodiments, there is no gap between the first cylindrical structure 61 and the second cylindrical structure 22, that is, the first cylindrical structure 61 and the second cylindrical structure 22 are tightly fitted, and the first cylindrical structure 61 and / or the second cylindrical structure 22 passes through the groove 51, which is also a feasible technical solution.

[0041] like Figure 1 As shown, the linkage component 60 starts rotating from the first position shown in the figure along direction B, corresponding to the rotation direction of the main shaft 70 as direction A. At this time, the first cylindrical structure 61 slides in the groove 51, and the distance between the first cylindrical structure 61 and the pin 40 is shortened, thereby compressing and storing energy in the energy storage element 30; as Figure 2As shown, the rotation of the linkage component 60 causes the energy storage element 30 to reach its maximum compression, thus maximizing the energy stored in the energy storage element 30. At this point, the linkage component 60 reaches its dead center position. After reaching this position, the linkage component 60 continues to rotate along direction B, as... Figure 3 As shown, after the linkage component 60 rotates past its dead center, the energy storage element 30 releases energy, driving the linkage component 60 to rotate rapidly, and the linkage component 60 rotates to reach the point shown in the figure. Figure 3 The second position shown.

[0042] As mentioned above, since the linkage component 60 is connected to the actuation mechanism of the contact head system, when the linkage component 60 is driven by, as Figure 1 The first position shown is the steering. Figure 3 In the second position shown, the contact state of the contact system switches from the first state to the second state; for example, the contact system switches from the open state to the closed state. At least a portion of the length of the groove 51 on the connecting rod 50 covers the energy storage compression stroke of the compression spring.

[0043] The energy storage element 30 and the connecting rod 50 constitute an energy storage assembly. In this embodiment, two sets of centrally symmetrical energy storage assemblies are provided, each cooperating with one of the two cylindrical structures of the linkage member 60. Compared to having only one set of energy storage assemblies, this embodiment has two sets of energy storage assemblies arranged symmetrically around the rotation axis of the linkage member 60, thereby achieving symmetrical compression energy storage, more balanced force distribution, and reducing friction between the main shaft 70 and the base 10, resulting in less wear on parts and significantly extending the product's service life.

[0044] The first bevel gear structure 81 of the first gear 80 is a sector bevel gear structure, and the second bevel gear structure 21 of the second gear 20 is a sector bevel gear structure. This makes the processing of parts simpler and requires less material, while also making full use of the installation space of the base 10, thus improving the miniaturization of the product.

[0045] The end of the slide groove 51 furthest from the center of the connecting rod 50 is defined as the outer end. The slide groove 51 of the connecting rod 50 can serve as a limiting structure to limit the rotation of the linkage member 60. For example, when the linkage member 60 is located at such a position... Figure 1 The first position shown or as Figure 3 In the second position shown, the cylindrical structure of the linkage member 60 is located at the outer end of the slide groove 51, thereby limiting the maximum rotation angle of the linkage member 60 by the slide groove 51. Of course, in some other embodiments, the slide groove 51 does not serve as a limiting structure, and the linkage member 60 is located as shown in the figure. Figure 1 The first position shown or as Figure 3In the second position shown, the cylindrical structure of the linkage member 60 does not reach the outer end of the slide groove 51. The rotation of the linkage member 60 is limited by other structures, which is also a feasible solution. For example, the two cylindrical structures of the linkage member 60 are located at the two ends of the sector bevel gear structure of the second bevel gear structure 21, respectively. The two cylindrical structures of the linkage member 60 serve as limiting mechanisms at the meshing ends of the bevel gear structures of the first gear 80 and the second gear 20, thereby limiting the rotation of the linkage member 60.

[0046] Reference Figure 7-8 The main shaft 70 includes a first shaft segment 71 and a second shaft segment 72, which are intermittently connected by a transmission. One end of the second shaft segment 72 is connected to the first shaft segment 71 by a transmission.

[0047] One end of the first shaft segment 71 is provided with a first transmission structure 711, and one end of the second shaft segment 72 is provided with a second transmission structure 721. The other end of the second shaft segment 72 is connected to a first gear 80. The first transmission structure 711 and the second transmission structure 721 are a set of shafts with keyed teeth and shaft holes with keyways that can cooperate to transmit power. The central angle corresponding to the keyway is larger than the central angle corresponding to the key teeth, thereby realizing an intermittent transmission connection between the first shaft segment 71 and the second shaft segment 72.

[0048] In this embodiment, a drive shaft portion 712 is provided at one end of the first shaft segment 71, and a key 711 is provided on the drive shaft portion 712. The drive shaft portion 712 with the key 711 is the first transmission structure. A drive shaft hole 722 is provided at one end of the second shaft segment 72, and a keyway 721 is provided in the drive shaft hole 722. The drive shaft hole 722 with the keyway 721 is the second transmission structure. The drive shaft 712 is rotatably fitted with the drive shaft hole 722. The key 711 fits into the keyway 721. The central angle N corresponding to the keyway 721 is greater than the central angle M corresponding to the key 711. There is a transmission clearance angle K between the keyway 721 and the key 711. The transmission clearance angle K is equal to the central angle N corresponding to the keyway 721 minus the central angle M corresponding to the key 711. Thus, after the first shaft segment 71 rotates through the transmission clearance angle K, it contacts and drives the second shaft segment 72, which in turn drives the second shaft segment 72 to rotate. The second shaft segment 72 drives the first gear 80 to rotate, which in turn drives the second gear 20 and the linkage component 60 to rotate, thereby compressing the energy storage element 30 and realizing energy storage.

[0049] When the linkage component 60 rotates to the dead center position, such as Figure 2As shown, the energy storage element 30 reaches its maximum energy storage value. When the main shaft 70 continues to rotate, the energy storage mechanism passes the dead point and quickly begins to release energy. Because the first shaft segment 71 and the second shaft segment 72 are intermittently connected by transmission, there is a transmission gap between the first shaft segment 71 and the second shaft segment 72. Therefore, in the initial stage of energy release, the energy storage mechanism drives the second shaft segment 72 to rotate within the travel range of the transmission gap angle K. After the second shaft segment 72 has rotated through the travel range of the transmission gap angle K, the second shaft segment 72 drives the first shaft segment 71 to rotate. This allows the energy storage mechanism to obtain a large acceleration in the initial stage of energy release, thereby increasing the initial movement speed of the actuation mechanism of the contact system, which is beneficial for realizing the closing / opening of the contact system. During manual closing / opening via the handle, the hand's movement is slow compared to the millisecond-level energy release speed of the energy storage element 30 (such as a spring). If there is no transmission clearance angle K between the first shaft segment 71 and the second shaft segment 72, the hand becomes part of the resistance during the initial energy release of the energy storage element 30. This results in the energy storage element 30 driving the main shaft 70 to rotate, which in turn drives the hand to rotate, leading to extremely poor operating feel and affecting the energy release speed of the energy storage element 30. This is especially dangerous during opening, as it slows down the contact separation speed and arc transfer speed, exacerbating contact erosion. In severe cases, it may prevent the arc from being broken, leading to safety risks.

[0050] In this embodiment, the transmission clearance angle K is approximately 25°. There are three key teeth 711 and three keyways 721. Of course, the number of key teeth 711 and keyways 721 can also be other than the number of key teeth 711 and keyways 721, as long as the number of key teeth 711 and keyways 721 corresponds.

[0051] This embodiment also provides a disconnecting switch, including the disconnecting switch operating mechanism 1 as described above.
