[0002] Switchgear, such as disconnecting switches, is an electrical product used to close and disconnect circuits. It typically includes at least one conductive device and an operating mechanism driven by the conductive device to close or open it. The closing or opening of the conductive device is achieved through the contact or separation of its internal moving contact mechanism and stationary contact. The speed at which the moving and stationary contacts open and the final gap size determine the electrical performance of the switching device. Existing switchgear is often limited by its size, preventing the achievement of larger opening gaps and faster opening and closing speeds, thus affecting product performance.

[0035] The following is in conjunction with the appendix Figure 1-9 The given embodiments further illustrate specific implementations of the switching device of the present invention. The switching device of the present invention is not limited to the descriptions of the following embodiments.

[0036] like Figure 9 As shown, the present invention provides a switching device, preferably an isolating switch, which includes an operating mechanism 1 and a conductive device 2. The operating mechanism 1 is driven and connected to the conductive device 2 to drive the conductive device 2 to conduct or disconnect. Further, the conductive device 2 includes a conductive device housing and a contact system and an arc-extinguishing system disposed within the conductive device housing and used in conjunction with it. The contact system includes a moving contact mechanism pivotally mounted on the conductive device housing and a stationary contact cooperating with the moving contact mechanism.

Two stationary contacts are disposed on both sides of the moving contact mechanism and respectively cooperate with both ends of the moving contact assembly. The arc-extinguishing system includes two arc-extinguishing chambers respectively disposed on both sides of the contact system.

[0037] like Figure 9 As shown, the switching device of the present invention has conductive devices 2 on both sides of its operating mechanism 1, which are respectively connected to its drive.

[0038] In another embodiment of the switching device of the present invention, a conductive device 2 connected to the operating mechanism 1 is provided only on the side of the operating mechanism 1.

[0039] like Figure 1-8 The figure shown is one embodiment of the operating mechanism 1.

[0040] The operating mechanism 1 includes an operating mechanism housing 1-0 and a second operating shaft assembly 1-1b, a second transmission structure 1-2b, an energy storage structure 1-3b, and a power output structure 1-4b respectively disposed within the operating mechanism housing 1-0. The second operating shaft assembly 1-1b is driven to cooperate with the second transmission structure 1-2b, and the second operating shaft assembly 1-1b rotates around its own axis to drive the second transmission structure 1-2b to reciprocate. The energy storage structure 1-3b includes an energy storage shaft 1-30b and a second energy storage spring structure 1-31b, one end of which is connected to the energy storage shaft. One end of 1-30b is driven and connected, and the other end is rotatably configured. The second transmission structure 1-2b is driven and engaged with the energy storage shaft 1-30b to drive its rotation, causing the second energy storage spring structure 1-31b to store energy. After the second energy storage spring structure 1-31b rotates past the second dead center position, it releases energy to drive the energy storage shaft 1-30b to rotate rapidly. The energy storage shaft 1-30b includes an energy storage shaft gear 1-301b, and the power output structure 1-4b includes a power output gear shaft 1-41b. The energy storage shaft gear 1-301b meshes with the power output gear shaft 1-41b to drive the power output gear shaft 1-41b to rotate. Specifically, the power output gear shaft 1-41b is driven and connected to the moving contact mechanism 2-1 of the conductive device 2. Of course, the power output gear shaft 1-41b can be directly or indirectly connected to the moving contact mechanism 2-1.

[0041] The operating mechanism's energy storage shaft drives the power output gear shaft to rotate through the cooperation of the energy storage shaft gear and the power output gear shaft. By setting a reasonable radius ratio between the energy storage shaft gear and the power output gear shaft, the breaking efficiency can be improved, and the opening distance of the contact system connected to the operating mechanism can be increased.

[0042] Preferred, such as Figure 1 As shown, the gear radius of the energy storage shaft gear 1-301b is larger than that of the power output gear shaft 1-41b, which is beneficial to increasing the rotational speed and angle of the power output gear shaft 1-41b, thereby increasing the breaking speed and opening distance of the conductive device 2 connected to the power output gear shaft 1-41b.

[0043] like Figure 1-2 As shown, the second transmission structure 1-2b includes a second transmission rack 1-22b, and the second operating shaft assembly 1-1b includes a second operating shaft 1-10b and a second drive gear 1-13b disposed on the second operating shaft 1-10b and rotating synchronously therewith. The second drive gear 1-13b meshes with the second transmission rack 1-22b. The second operating shaft assembly 1-1b and the second transmission structure 1-2b use a gear and rack engagement method for transmission, which is beneficial to improving transmission efficiency and reliability.

[0044] like Figure 1 , 4As shown in Figure 5, the second transmission structure 1-2b further includes a second transmission structure drive part 1-21b, which is a second drive finger extending and protruding towards the energy storage shaft 1-30b; the energy storage shaft 1-30b further includes a second driven structure, which includes two spaced-apart force-bearing sides 1-302b of the energy storage shaft, and the second transmission structure drive part 1-21b is located between the two force-bearing sides 1-302b of the energy storage shaft, and cooperates with the two force-bearing sides 1-302b of the energy storage shaft to drive the energy storage shaft 1-30b to rotate in opposite directions.

[0045] like Figure 6 As shown, the energy storage shaft 1-30b further includes an energy storage shaft connecting column 1-303b disposed at one axial end thereof; as Figure 1-2 As shown, the second energy storage spring structure 1-31b includes a second energy storage spring 1-310b, a spring support rod 1-311b, a spring support seat 1-312b, and a limiting shaft 1-313b. The spring support seat 1-312b is fixedly mounted on the operating mechanism housing 1-0 of the operating mechanism. One end of the spring support rod 1-311b is rotatably connected to the energy storage shaft connecting column 1-303b, and the other end passes through the spring support seat 1-312b and is connected to the limiting shaft 1-313b. The limiting shaft 1-313b and the spring support seat 1-310b are connected to each other. -312b is a limiting fit to prevent the spring support rod 1-311b from disengaging from the spring support seat 1-312b. The second energy storage spring 1-310b is sleeved on the spring support rod 1-311b and its two ends are in elastic contact with the spring support rod 1-311b and the spring support seat 1-312b, respectively. The energy storage shaft 1-30b rotates and drives the spring support rod 1-311b to move relative to the spring support seat 1-312 through the energy storage shaft connecting column 1-303b, so that the second energy storage spring 1-310b is compressed to store energy.

[0046] In another embodiment, the spring support rod 1-311b can also be a telescopic rod, and the spring support seat 1-312b and the limiting shaft 1-313b can be omitted. The second energy storage spring 1-310b is sleeved on the telescopic rod. One end of the telescopic rod is rotatably connected to the energy storage shaft connecting column 1-310b, and the other end is rotatably mounted on the operating mechanism housing 1-0 of the operating mechanism 1. When the second energy storage spring 1-310 is compressed or relaxed, the telescopic rod shortens or extends.

[0047] Preferred, such as Figure 6 As shown, the energy storage shaft 1-30b includes two energy storage shaft connecting columns 1-303b arranged parallel to each other on one of its axial ends. Two sets of second energy storage spring structures 1-31b are respectively arranged on the radial sides of the energy storage shaft 1-30b and are driven and cooperated with the two energy storage shaft connecting columns 1-303b respectively.

[0048] like Figure 1-2 As shown, the operating mechanism 1 includes two symmetrically arranged energy storage shafts 1-30b and two symmetrically arranged power output gear shafts 1-41b, with the energy storage shaft gears 1-301b of the two energy storage shafts 1-30b meshing with the two power output gear shafts 1-41b respectively. Further, as... Figure 1-2 As shown, one end of the spring support rod 1-311b of each group of the second energy storage spring structure 1-31b is located between the two energy storage shafts 1-30b and is rotatably connected to the two corresponding energy storage shaft connecting columns 1-303b of the two energy storage shafts 1-30b respectively.

[0049] like Figure 1-2 As shown, the power output structure 1-4b further includes an output structure bracket 1-5b fixedly connected to the operating mechanism housing 1-0, and two power output gear shafts 1-41b are rotatably mounted on both sides of the output structure bracket 1-5b, with each power output gear shaft 1-41b located between the output structure bracket 1-5b and the operating mechanism housing 1-0.

[0050] Preferred, such as Figure 1-2 As shown, the output structure bracket 1-5b includes two mutually cooperating single-sided structural brackets. The two single-sided structural brackets are respectively fixedly connected to a pair of opposite side walls of the operating mechanism housing 1-0. Each single-sided structural bracket has a groove on the side facing the operating mechanism housing 1-0 for accommodating the power output gear shaft 1-41b. The bottom wall of the groove has a shaft hole for rotatably mounting the power output gear shaft 1-41b. The single-sided structural bracket has a positioning boss on the side facing the second operating shaft 1-10b. The positioning boss has a half-shaft groove, and two half-shaft grooves are joined together to form an operating shaft mounting hole for the second operating shaft 1-10b to be rotatably inserted. Further, as... Figure 1-2 As shown, each of the single-sided structural supports has connecting ears at both ends for fixed connection with the operating mechanism housing 1-0.

[0051] Preferred, such as Figure 3 As shown, an annular limiting platform 1-12b is also provided on the circumferential side of the second operating shaft 1-10b. The annular limiting platform 1-12b cooperates with the output structure bracket 1-5b to limit and prevent the second operating shaft 1-10b from moving away from the second transmission structure 1-2b.

[0052] like Figure 1-2As shown, the spring support rod 1-311b is configured as follows to drive and cooperate with the two symmetrically arranged energy storage shafts 1-30b: the spring support rod 1-311b includes a support rod connecting part and a support rod bearing part. The support rod connecting part is a U-shaped structure, which includes a pair of support rod connecting side plates, which are rotatably connected to the two energy storage shaft connecting columns 1-303 of the two energy storage shafts 1-30b respectively. The bottom plate of the U-shaped structure of the support rod connecting part is connected to one end of the support rod bearing part. The other end of the support rod bearing part is used to connect to the limiting shaft 1-313b. The second energy storage spring is sleeved on the support rod bearing part and its two ends are in elastic contact with the spring support seat 1-312b and the support rod connecting part respectively.

[0053] like Figure 4 As shown, the second transmission structure 1-2b includes two parallel and spaced-apart second transmission structure drive units 1-21b, which respectively drive and cooperate with two symmetrically arranged energy storage shafts 1-30b. Specifically, as... Figure 4 As shown, this is one embodiment of the second transmission structure 1-2b: the second transmission structure 1-2b includes a second transmission structure base plate 1-200b and a second transmission structure side plate 1-201b. The two second transmission structure side plates 1-201b are bent and connected to the second transmission structure base plate 1-200b and form an overall U-shaped structure. The side of the second transmission structure side plate 1-201b away from the second transmission structure base plate 1-200b is provided with a second transmission structure driving part 1-21b. The drive unit 1-21b of the transmission structure is symmetrically arranged and is driven and cooperated with the second driven structure of the two energy storage shafts 1-30b respectively. The inner side wall of one second transmission structure side plate 1-201b (that is, the side wall opposite to the other second transmission structure side plate 1-201b) is provided with a second transmission rack 1-22b. The bottom plate 1-200b of the second transmission structure is provided with a second transmission structure clearance hole 1-23b in the middle for the second operating shaft 1-10b to pass through.

[0054] As another embodiment of the second transmission structure 1-2b: the second transmission structure 1-2b may not have the second transmission structure side plate 1-201b. Instead, two second transmission structure drive parts 1-21b are arranged in parallel and spaced apart on the second transmission structure base plate 1-200b and located on both sides of the second transmission structure clearance hole 1-23b. A second transmission rack 1-22b is provided on one inner side wall of the second transmission structure clearance hole 1-23b.

[0055] like Figure 5-6The image shows one embodiment of the energy storage shaft 1-30b: The energy storage shaft 1-30b includes an energy storage shaft body 1-300b, an energy storage shaft gear 1-301b, a second driven structure, and an energy storage shaft connecting column 1-303b.

The second driven structure includes two symmetrically spaced energy storage shaft force-bearing surfaces 1-302b. The two energy storage shaft connecting columns 1-303b are parallel to each other and spaced apart on one axial end of the energy storage shaft body 1-300b, symmetrically distributed on both sides of the axis of the energy storage shaft 1-30b. The extending direction of the energy storage shaft connecting columns 1-303b is parallel to the axial direction of the energy storage shaft 1-30b. Further, the energy storage shaft force-bearing surface 1-302b is an arc-shaped surface.

[0056] like Figure 1-2 As shown, the operating mechanism 1 further includes an auxiliary switch and an auxiliary switch drive structure 1-6b. The second operating shaft assembly 1-1b further includes an auxiliary drive gear 1-11b that is mounted on the second operating shaft 1-10b and rotates synchronously therewith. The auxiliary switch drive structure 1-6b includes an auxiliary driven rack 1-61b, and the auxiliary drive gear 1-11b meshes with the auxiliary driven rack 1-61b. When the second operating shaft 1-10b rotates, the auxiliary switch drive structure 1-6b is driven to move to trigger the auxiliary switch through the engagement of the auxiliary drive gear 1-11b and the auxiliary driven rack 1-61b. Further, as... Figure 1-2 As shown, the operating mechanism 1 of the second embodiment includes two auxiliary switches, namely a first auxiliary switch 1-70b and a second auxiliary switch 1-71b respectively disposed on both sides of the first operating shaft 1-10; the auxiliary switch driving structure 1-6b also includes a driving structure body 1-60b, a first trigger arm 1-62b and a second trigger arm 1-63b, the first trigger arm 1-62b and the second trigger arm 1-63b are respectively connected to both ends of the driving structure body 1-60b and respectively drive and cooperate with the first auxiliary switch 1-70b and the second auxiliary switch 1-71b, and the auxiliary driven rack 1-61b is disposed on the driving structure body 1-60b.

[0057] like Figure 8The diagram shows an embodiment of the auxiliary switch drive structure 1-6b: The auxiliary switch drive structure 1-6b includes a drive structure body 1-60b, an auxiliary driven rack 1-61b, a first trigger arm 1-62b, and a second trigger arm 1-63b. The drive structure body 1-60b is a square frame structure with a drive structure clearance hole 1-64b in its middle for the second operating shaft 1-10b to pass through. The auxiliary driven rack 1-61b is disposed on an inner sidewall of the drive structure clearance hole 1-64b. The first trigger arm 1-62b and the second trigger arm 1-63b are respectively connected to both ends of the drive structure body 1-60b and extend toward the first auxiliary switch 1-70b and the second auxiliary switch 1-71b, respectively.

[0058] Preferred, such as Figure 8 As shown, the first trigger arm 1-62b includes a first trigger side and a first release side arranged sequentially along its extension direction. The first release side is located close to the drive structure body 1-60b, and the first trigger side is higher than the first release side in the direction toward the first auxiliary switch 1-70b. The second trigger arm 1-63b includes a second trigger side and a second release side arranged sequentially along its extension direction. The second trigger side is located close to the drive structure body 1-60b, and the second trigger side is higher than the second release side in the direction toward the second auxiliary switch 1-71b.

[0059] Preferably, the first auxiliary switch 1-70b and the second auxiliary switch 1-71b are triggered simultaneously. Further, as... Figure 1-2 As shown, the auxiliary switch is a micro switch, which includes a drive rod. The drive rods of the two micro switches are simultaneously pressed or released by the auxiliary switch drive structure 1-6b.

[0060] The following will combine Figure 1 The operation process of the operating mechanism 1 is described below:

[0061] One end of the second operating shaft 1-10b protrudes outside the operating mechanism housing 1-0 for human operation. Driven by external force, the second operating shaft 1-10b rotates, causing the second drive gear 1-13b to rotate synchronously. Through the engagement of the second drive gear 1-13b and the second transmission rack 1-22b, the second operating shaft 1-10b drives the second transmission structure 1-2b to slide on the operating mechanism housing 1-0. The second transmission structure 1-2b, through its drive part 1-21b, pushes the energy storage shaft force-bearing side 1-302b of the energy storage shaft 1-30b, causing the energy storage shaft 1-30b to rotate. The energy storage shaft 1-30b then drives the second... The rotation of the energy storage spring structure 1-31b compresses the second energy storage spring to store energy. When the second energy storage spring structure 1-31b rotates to the second dead point position, the axis of the second energy storage structure 1-31b coincides with the axis of the energy storage shaft 1-30b. After the energy storage shaft 1-30b drives the second energy storage spring structure 1-31b to rotate past the second dead point position, the second energy storage spring structure 1-31b drives the energy storage shaft 1-30b to rotate rapidly. The energy storage shaft 1-30b drives the power output gear shaft 1-41b to rotate rapidly, so that it outputs driving force to drive the moving contact mechanism 2-1 of the conductive device 2 to rotate, so that the conductive device 2 is connected or disconnected.

[0062] like Figure 1 The image shows one layout of the operating mechanism 1:

[0063] The second operating shaft 1-10b of the second operating shaft assembly 1-1b is arranged along the length of the operating mechanism 1. One end of the second operating shaft 1-10b protrudes outside the length of the operating mechanism for operation by external force. The second transmission structure 1-2b is slidably disposed at the other end of the operating mechanism along the length of the operating mechanism. The first auxiliary switch 1-70b and the second auxiliary switch 1-71b are arranged side by side at intervals along the width of the operating mechanism. The auxiliary switch drive structure 1-6b, the power output structure 1-4b, and the second energy storage spring structure are arranged sequentially along the length of the operating mechanism and located at the auxiliary switch (i.e., the first auxiliary switch 1-70b). Between the second auxiliary switch 1-71b and the second transmission structure 1-2b, two power output gear shafts 1-41b are arranged side-by-side and spaced apart on both sides of the second operating shaft 1-10b along the thickness direction of the operating mechanism 1. Two energy storage shafts 1-30b are also arranged side-by-side and spaced apart on both sides of the second operating shaft 1-10b along the thickness direction of the operating mechanism 1. The output structure bracket 1-5b of the power output structure 1-4b is located between the two power output gear shafts 1-41b. The two power output gear shafts 1-41b are rotatably mounted on the output structure bracket 1-5b, and the second operating shaft 1-10b passes through the middle of the output structure bracket 1-5b. Specifically, as shown... Figure 1 direction shown, Figure 1 The vertical direction is the length direction of operating mechanism 1. Figure 1The left and right directions are the width direction of the operating mechanism 1. Figure 1 The inner and outer directions are the thickness directions of the operating mechanism 1.

[0064] like Figure 1 As shown, the axial direction of the second operating shaft 1-10b is perpendicular to the axial direction of the power output gear shaft 1-41b, perpendicular to the axial direction of the energy storage shaft 1-30b, perpendicular to the moving direction and plane of the second transmission structure 1-2b, and perpendicular to the moving direction of the auxiliary switch drive structure 1-6b; the axial direction of the power output gear shaft 1-41b is parallel to the axial direction of the energy storage shaft 1-30b, the two are coplanar, and both are parallel to the moving direction and plane of the second transmission structure 1-2b, and parallel to the plane of the auxiliary switch drive structure 1-6b.

[0065] like Figure 9 As shown, in the switching device of the present invention, the operating mechanism 1 is driven to connect with the conductive device 2 through a first connecting structure, and the conductive devices 2 are driven to connect with each other through a second connecting structure. The first connecting structure includes the power output shaft of the operating mechanism 1 and the contact support 2-10 of the conductive device 2. A first free stroke is provided between the power output shaft and the contact support, so that the power output shaft rotates through a preset angle before engaging with the contact support and driving it to rotate. The second connecting structure includes the contact supports of two adjacent conductive devices 2 and a shaft connector 4. The shaft connector 4 is respectively limited to the two contact supports at both ends of its axial direction and rotates synchronously. Further, the power output shaft of the operating mechanism is the power output gear shaft 1-41b of the operating mechanism 1, but other operating mechanisms can also be used.

[0066] Specifically, when the power output gear shaft 1-41b of the operating mechanism 1 rotates through the first free stroke relative to the contact support, the second energy storage spring completes energy storage. When the power output gear shaft 1-41b continues to rotate, that is, after the second energy storage spring 1-31b rotates through the second dead point position, the second energy storage spring begins to release energy and drives the contact support to rotate rapidly through the power output gear shaft 1-41b, so that the conductive device 2 can be quickly closed or opened.

[0067] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
