Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and more particularly to a 10KV outdoor vacuum circuit breaker. Background Art

[0002] Outdoor vacuum circuit breakers are widely used in all aspects of the power system, including transmission, distribution and consumption. They are an indispensable and important part of the power system. In new energy grid-connected projects, such as photovoltaic and wind power, outdoor vacuum circuit breakers also play an important role, ensuring the stable grid connection and efficient utilization of new energy. Outdoor vacuum circuit breakers are mainly composed of porcelain sleeves, vacuum interrupter chambers, operating mechanisms and other parts. They have the function of breaking circuits and ensuring the safe and stable operation of power systems.

[0003] When an outdoor vacuum circuit breaker is in the closed condition, its vacuum interrupter and isolation mechanism must simultaneously maintain a conductive state. When in the open condition, the two must work together to achieve complete electrical isolation. According to power system operating procedures, the power-off operation must strictly follow the standard operating sequence of "first opening the vacuum circuit breaker main contacts, then opening the disconnector." The power-on operation must follow the reverse process of "first closing the disconnector to establish a current-carrying path, then closing the vacuum circuit breaker to put it into operation." The essence of this operating logic is to utilize the transient arc suppression capability of the vacuum circuit breaker's core interrupter to create a physical protection barrier for the disconnector, thereby ensuring that arc discharges prevent corrosive damage to primary equipment during the transient process of opening and closing. Failure to follow the established operating procedures will result in serious violations of the live disconnector operation, directly causing arc flash, equipment damage, and cascading failures in the power system, while also exposing operators to occupational health risks such as arc burns.

[0004] In the existing technology, the main contact opening and closing mechanism of the vacuum interrupter and the disconnector operating system adopt a non-linked independent design, and the two lack an interlocking mechanism. Although this design scheme realizes modular control of the switchgear, it exposes significant operational safety defects. When the operation and maintenance personnel mistakenly execute the opening and closing sequence, the disconnector will be opened and closed while energized because the system is not equipped with operation sequence verification and forced locking functions. Such illegal operations will cause multiple risks: First, the energized opening and closing of the disconnector will directly induce arc discharge, causing contact erosion and deterioration of the equipment insulation performance. Second, the arc energy may cause insulation flash of adjacent equipment through conduction or radiation, resulting in cascading failures in the power system. Finally, the operator may be exposed to the high-temperature arc radiation area, posing an occupational safety and health hazard. The technical problem is essentially that the switchgear operation process lacks a logical interlocking protection mechanism, and fails to use technical means to force the operator's behavior sequence to be regulated, making the operational safety of key equipment in the power system completely dependent on the subjective judgment of the personnel, with a significant risk of human error. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a 10KV outdoor vacuum circuit breaker to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a 10KV outdoor vacuum circuit breaker, comprising a main body, an operating mechanism, an isolation mechanism and a control unit, The control unit realizes the action sequence interlocking of the operating mechanism and the isolation mechanism through a single-axis transmission structure. When opening, the operating mechanism acts before the isolation mechanism, and when closing, the isolation mechanism acts before the operating mechanism.

[0007] Preferably, the main body is provided with a vacuum portion, which includes a vacuum interrupter chamber and an operating mechanism located below the vacuum interrupter chamber; The operating mechanism includes a first rotating shaft, and the rotation of the first rotating shaft can control the opening and closing of the vacuum interrupter.

[0008] Preferably, the main body is provided with an isolation portion, which includes a connecting plate and an isolation mechanism; The isolation mechanism includes a second rotating shaft, and the rotation of the second rotating shaft can control the opening and closing of the isolation mechanism.

[0009] Preferably, the isolation mechanism includes an elastic buffer component, which is hingedly matched with the vertical slot of the support frame through a rocker rod and is provided with an axial reset device for controlling the buffer stroke of the isolation mechanism.

[0010] Preferably, the control unit includes: a linear transmission assembly linked to the operating mechanism, a rotary transmission assembly linked to the isolation mechanism, and a control box integrating a driving shaft and a control rod. The driving shaft synchronously drives the two sets of transmission assemblies through the circular rings at both ends.

[0011] Preferably, the linear transmission assembly comprises an eccentric transmission structure and a linear drive component, wherein the eccentric transmission structure forms a displacement conversion mechanism with a guide column of the linear drive component through a guide groove.

[0012] Preferably, the operating mechanism and the linear transmission assembly are rotated and controlled via a mechanical linkage mechanism.

[0013] Preferably, the rotary transmission assembly comprises a track linkage component and a sliding drive component, wherein the rotation groove of the track linkage component and the plug post of the sliding drive component form a cam follower mechanism.

[0014] Preferably, a guide sliding structure is provided in the control box, and the structure comprises mutually cooperating slide rails and a slide plate with a connecting rod.

[0015] Preferably, the isolation mechanism and the rotation transmission assembly are controlled by a mechanical transmission mechanism.

[0016] The technical effects and advantages of the present invention are as follows: 1. The present invention utilizes the coordinated arrangement of the main body, vacuum interrupter, isolation mechanism, and operating mechanism. When the circuit is opened or closed, the high insulation and arc-extinguishing properties of the vacuum medium are utilized to rapidly diffuse and cool the arc generated between the contacts when the circuit breaker is opened. Utilizing the characteristics of metal vapor condensation and rapid recombination of charged particles, the arc is extinguished at the natural zero-crossing point of the current, thereby safely disconnecting the circuit. This process can effectively prevent equipment damage or power accidents caused by arc reignition.

[0017] 2. The present invention adopts an integrated operating mechanism design through the coordinated arrangement of a control rod, a driving shaft, a cam, a disc, a slide, a guide column, a guide groove, a plug column, a rotating groove, a first rotating shaft and a second rotating shaft. The control system innovatively breaks through the "break first and then isolate" timing operation specification of traditional switchgear, and realizes the intrinsically safe reconstruction of the electrical operation logic through a single control rod multi-dimensional linkage mechanism. Its technical implementation path is: during the opening process, the control unit drives the composite connecting rod mechanism to first complete the zero-current disconnection of the main contacts of the vacuum arc chamber, and then automatically triggers the separation action of the isolating knife switch. When closing, it follows the reverse operation sequence, and the isolation mechanism first establishes a current-carrying channel, and then drives the arc chamber contacts to realize circuit conduction. This design completely eliminates the operator's reliance on subjective judgment of the opening and closing timing. This innovative architecture not only realizes the miniaturization and integration of switchgear, but also constructs multiple barriers for arc protection through forced timing control strategies, providing a paradigm-level solution for the operational safety of key equipment in the power system.

DETAILED DESCRIPTION

[0025] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example 1 See also Figures 1 to 6 As shown, this embodiment provides a KV outdoor vacuum circuit breaker, including a main body 1, a vacuum part 2, which includes a vacuum interrupter 21 and an operating mechanism 22, the operating mechanism 22 is used to control the opening and closing of the vacuum interrupter 21, an isolation part 3, which includes a connecting plate 31, and an isolation mechanism 32 is provided on the connecting plate 31. The control part 4 includes a driving shaft 43, and a linear transmission component 41 connected to the operating mechanism 22 and a rotating transmission component 42 connected to the isolation mechanism 32 are provided on the outside of the driving shaft 43. When the driving shaft 43 rotates, the operating mechanism 22 and the isolation mechanism 32 act in sequence according to its rotation direction: when rotating forward, the operating mechanism 22 moves first and the isolation mechanism 32 moves later; when rotating reversely, the isolation mechanism 32 moves first and the operating mechanism 22 moves later.

[0027] The operating mechanism 22 includes a first rotating shaft 221, and the contacts in the vacuum arc chamber 21 can be contacted or separated by rotating the first rotating shaft 221. The connection relationship between the first rotating shaft 221 and the operating mechanism 22 is the existing technology and will not be repeated in this application, thereby realizing the opening or closing of the operating mechanism 22. During the opening and closing process, an arc will be formed between the contacts, and the porcelain sleeve in the vacuum arc chamber 21 can play a role in suppressing the arc.

[0028] The isolation mechanism 32 includes a second rotating shaft 321 , and the isolation mechanism 32 can be controlled to open or close by rotating the second rotating shaft 321 .

[0029] A support frame 322 is fixedly connected to the connecting plate 31, and a vertical slot 323 is provided on the support frame 322. A rocker arm 324 corresponding to the vertical slot 323 is fixedly connected to the second rotating shaft 321. The free end of the rocker arm 324 is hinged to a limiting shaft 325. The shape of the limiting shaft 325 is that the diameter of one end is larger than the diameter of the other end. There is a stepped surface at the intersection of the two ends of the limiting shaft 325. The end of the limiting shaft 325 extends into the vertical slot 323 and is hinged to the support frame 322. The limiting shaft 325 is provided with a first spring 326 located between its stepped surface and the support frame 322.

[0030] In actual use, there is an energy storage device in the operating mechanism 22. The function of the energy storage device is to provide power for the closing and separating of the operating mechanism 22. The energy storage device can be stored manually or by using a motor. This technology is an existing technology and will not be repeated here. When the vacuum circuit breaker is in a closed state and needs to be disconnected, it is necessary to first control the operating mechanism 22 to disconnect, and then control the isolation mechanism 32 to disconnect. A high-voltage arc will be generated at the moment the circuit is disconnected. When the operating mechanism 22 is disconnected, the vacuum arc chamber 21 can extinguish the arc. The specific operation is to rotate the first shaft 221. The first shaft 221 rotates, thereby realizing the disconnection between the contacts in the vacuum arc chamber 21 through the operating mechanism 22. A high-voltage arc will be generated at the moment the contacts are disconnected. The vacuum arc chamber 21 uses high vacuum to reduce ions and molecules, thereby quickly extinguishing the arc. At this time, the entire circuit is already in a disconnected state.

[0031] When the contacts in the vacuum interrupter 21 of the vacuum circuit breaker are disconnected, the second rotating shaft 321 is controlled to rotate, and the second rotating shaft 321 drives the isolation mechanism 32 to rotate. At the same time, the second rotating shaft 321 drives the rocker arm 324 to swing upward, and the rocker arm 324 drives the limit shaft 325 to swing upward. When the second rotating shaft 321 drives the rocker arm 324 to swing upward to the extreme position, the isolation mechanism 32 is in an open state. At this time, due to the limitation of the first spring 326, the entire isolation mechanism 32 remains in an open state in the absence of external force. At this time, the isolation mechanism 32 is open, and the circuit is in a disconnected state.

[0032] When the vacuum circuit breaker is in the open state and needs to be closed, it is necessary to first control the isolation mechanism 32 to close, and then control the operating mechanism 22 to close. Because a high-voltage arc will be generated at the moment the circuit is closed, when the operating mechanism 22 is closed, the vacuum arc extinguishing chamber 21 can extinguish the arc. The specific operation is to control the second shaft 321 to rotate, and the second shaft 321 drives the isolation mechanism 32 to rotate. At the same time, the second shaft 321 drives the rocker 324 to swing downward, and the rocker 324 drives the limit shaft 325 to swing downward. When the second shaft 321 drives the rocker 324 to swing downward to the extreme position, the isolation mechanism 32 is in a closed state at this time. At this time, due to the limitation of the first spring 326, the entire isolation mechanism 32 remains in a closed state in the absence of external force.

[0033] When the isolation mechanism 32 is closed, the first rotating shaft 221 is rotated. The first rotating shaft 221 rotates, thereby realizing the movement of the contacts in the vacuum interrupter 21 toward each other through the operating mechanism 22. A high-voltage arc is generated at the moment the contacts touch. The vacuum interrupter 21 uses high vacuum to reduce ions and molecules, thereby quickly extinguishing the arc. At this time, the entire circuit is already in a closed state. When the circuit is opened or closed, the high insulation and arc extinguishing characteristics of the vacuum medium are utilized to rapidly diffuse and cool the arc generated between the contacts when the circuit breaker is opened. The characteristics of metal vapor condensation and rapid recombination of charged particles are utilized to extinguish the arc at the natural zero crossing point of the current, thereby safely cutting off the circuit. This process can effectively avoid equipment damage or power accidents caused by the reignition of the arc.

[0034] Example 2 On the basis of the above embodiment, since the main contact opening and closing mechanism of the vacuum interrupter 21 and the disconnector operating system adopt a non-linked independent design, the two lack an interlocking mechanism. When the operation and maintenance personnel mistakenly execute the opening and closing sequence, the disconnector will be opened and closed in a live state. The live opening and closing of the disconnector will directly induce arc discharge, causing contact erosion and deterioration of the equipment insulation performance. The arc energy may cause insulation flashover of adjacent equipment through conduction or radiation, resulting in cascading failures in the power system, and the operator may be exposed to the high-temperature arc radiation area.

[0035] See also Figures 1 to 6 As shown, the control unit 4 includes a linear transmission component 41 for controlling the opening and closing of the operating mechanism and a rotary transmission component 42 for controlling the opening and closing of the isolation mechanism 32. It also includes a driving shaft 43. When the circuit needs to be disconnected, the driving shaft 43 rotates to realize that the operating mechanism 22 is disconnected first and the isolation mechanism 32 is disconnected later. When the circuit needs to be closed, the isolation mechanism 32 is closed first and the operating mechanism 22 is closed later.

[0036] The control unit 4 includes a control box 44, which is fixedly connected to the main body 1. The driving shaft 43 is rotatably connected to the control box 44. The front end of the driving shaft 43 passes through the control box 44 and is provided with a control rod 45. Both ends of the control rod 45 are provided with rings 46.

[0037] The linear transmission assembly 41 includes a disc 411, which is coaxially fixedly connected to the driving shaft 43. A guide groove 412 is provided on the disc 411. Figure 5 The guide groove 412 shown has two states, one of which is a small radius state and the other is a large radius state. A first rack 413 is slidably connected in the main body 1. The free end of the first rack 413 extends into the control box 44 and is provided with a guide column 414 inserted into the guide groove 412.

[0038] A first gear 415 is coaxially fixedly connected to the first rotating shaft 221 , and the first gear 415 can mesh with the first rack 413 .

[0039] The rotary transmission assembly 42 includes a cam 421 coaxially fixedly connected to the driving shaft 43. Figure 6 The cam 421 shown is provided with a rotating groove 424, and the shape of the rotating groove 424 is the same as the outline of the cam 421. The rotating groove 424 exists in two states, one is a small diameter state, and the other is a large diameter state. A slide plate 422 is provided in the control box 44, and a connecting rod 427 is fixedly connected to the slide plate 422, and a column 428 inserted into the rotating groove 424 is fixedly connected to the connecting rod 427.

[0040] A slide rail 423 is provided in the control box 44 , and the slide plate 422 is slidably connected to the slide rail 423 .

[0041] A second rack 425 is fixedly connected to the upper end of the slide plate 422 , and a second gear 426 that can mesh with the second rack 425 is coaxially fixedly connected to the second rotating shaft 321 .

[0042] In actual use, based on the above embodiment, when the vacuum circuit breaker is in the closed state and needs to be disconnected, the right side of the control rod 45 is pushed downward, and the control rod 45 drives the active shaft 43 to rotate clockwise, and the active shaft 43 drives the disc 411 and the cam 421 to rotate clockwise synchronously, and the disc 411 drives the guide groove 412 to rotate clockwise, so that the guide column 414 moves from the small radius state to the large radius state in the guide groove 412, and the guide column 414 drives the first rack 413 to move to the right, and the first rack 413 engages with the first gear 415, so that the first rotating shaft 221 rotates counterclockwise. When the guide column 414 moves to the large radius state in the guide groove 412, the first rotating shaft 221 rotates counterclockwise to the limit position, and the first rotating shaft 221 drives the operating mechanism 22 to realize the disconnection operation of the contacts in the vacuum interrupter 21.

[0043] In the above process, the driving shaft 43 drives the cam 421 to rotate clockwise, and the cam 421 drives the rotating groove 424 to rotate clockwise, so that the plug post 428 moves in the small diameter state of the rotating groove 424. During this process, the positions of the plug post 428 and the connecting rod 427 relative to the cam 421 remain unchanged. As the driving shaft 43 continues to rotate, the plug post 428 is transformed from the small diameter state to the large diameter state in the rotating groove 424. During the transformation process, the plug post 428 is pushed by the guide groove 412 to drive the slide plate 422 downward through the connecting rod 427, and the slide plate 422 drives the second rack 425 to move downward. During the downward movement of the second gear 426, it meshes with the second rack 425, causing the second rotating shaft 321 to rotate upward, and the second rotating shaft 321 drives the rocking rod 324 to swing upward. The rocking rod 324 The limit shaft 325 is driven to swing upward and compress the first spring 326. When the plug 428 moves to the large diameter state in the rotating groove 424, the second rotating shaft 321 drives the rocker arm 324 to move upward to the limit position. At this time, the isolation mechanism 32 is disconnected, and the rotating shaft remains stationary under the action of the first spring 326, so that the isolation mechanism 32 is in a disconnected state without external intervention. At this time, the circuit is disconnected. During this process, the guide column 414 slides in the large diameter in the guide groove 412, and the first rack 413 does not move. The operating mechanism 22 is in a disconnected state. This process only requires controlling the swing of the control rod 45. When the vacuum circuit breaker is disconnected in the closed state, the operating mechanism 22 first drives the contacts in the vacuum arc chamber 21 to disconnect. After the contacts are disconnected, the isolation mechanism 32 is disconnected.

[0044] When the vacuum circuit breaker is in the open state and needs to be closed, the left side of the control rod 45 is pushed downward, and the control rod 45 drives the driving shaft 43 to rotate counterclockwise, and the driving shaft 43 drives the cam 421 to rotate counterclockwise, and the cam 421 drives the rotating groove 424 to rotate counterclockwise, so that the plug post 428 switches from the large diameter state to the small diameter state in the rotating groove 424, so that the plug post 428 drives the connecting rod 427 to move upward, and the connecting rod 427 drives the slide 422 to move upward, and the slide 422 drives the second rack 425 to engage with the second gear 426 , so that the second gear 426 drives the second rotating shaft 321 to rotate downward, the second rotating shaft 321 drives the rocker rod 324 to swing upward, the rocker rod 324 drives the limiting shaft 325 to swing upward and compresses the first spring 326. When the plug 428 switches to the small diameter state in the rotating groove 424, the second rotating shaft 321 drives the limiting shaft 325 to swing downward to the limit position through the rocker rod 324. At this time, under the action of the first spring 326, the second rotating shaft 321 remains stationary, and the second rotating shaft 321 drives the isolation mechanism 32 to close.

[0045] In the above process, the guide column 414 is in the large diameter state in the guide groove 412, and the operating mechanism 22 is in the disconnected state. As the driving shaft 43 continues to rotate counterclockwise, the guide column 414 switches from the large diameter state to the small diameter state in the guide groove 412, so that the guide column 414 drives the first rack 413 to move left, and the first rack 413 drives the first gear 415 to rotate clockwise, so that the first gear 415 drives the first rotating shaft 221 to rotate clockwise. When the guide column 414 switches to the large diameter state in the guide groove 412, the first rotating shaft 221 drives the contacts in the vacuum interrupter 21 to close through the operating mechanism 22. In the above process, the plug column 428 moves in the small diameter state in the rotating groove 424. This process The slide plate 422 does not move, that is, the second rotating shaft 321 remains stationary, and the switch of the isolation mechanism 32 is in a closed state. At this time, under the limit of the operating mechanism 22, the first rotating shaft 221 is limited, and the first rotating shaft 221 cannot rotate, so that the driving shaft 43 cannot rotate, so that the control board is stationary in the absence of external force, and the circuit is in a closed state. This process only requires controlling the swing of the control rod 45 so that when the vacuum circuit breaker is disconnected in the disconnected state, the isolation mechanism 32 is closed first. After the isolation mechanism 32 is closed, the entire circuit is still in a disconnected state, and then the operating mechanism 22 drives the contacts in the vacuum interrupter 21 to contact, so that the entire circuit is closed, avoiding the generation of an arc when the isolation mechanism 32 is closed.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
