Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, and more particularly to an outdoor AC high-voltage vacuum circuit breaker. Background Technology

[0002] Outdoor high-voltage vacuum circuit breakers are widely used in overhead power distribution networks, rural power grids and other open-air power distribution scenarios. The spring-operated mechanism is the core component of the circuit breaker to realize energy storage and opening / closing actions. It mainly relies on the cooperation structure of the internal ratchet and pawl to transmit torque to complete the energy storage locking, thereby ensuring the safe operation of the equipment during normal energy storage.

[0003] Existing energy storage ratchet and pawl structures are mostly unidirectional locking, unable to rotate in reverse. When problems such as energy storage overshoot, transmission jamming, or assembly misalignment occur, the mechanism can only be disassembled to reset, making maintenance and debugging operations cumbersome. At the same time, during the performance testing phase, due to the constraint of the unidirectional structure, the ratchet cannot be adjusted for steering, nor can it be used to perform idle testing with the energy storage rod. When encountering energy storage overshoot or jamming faults, disassembly and reset are still required, and only a batch testing mode can be adopted, resulting in low overall testing efficiency.

At this time, the tripping assembly and the arc extinguishing assembly maintain normal connection. When an abnormal voltage fault occurs, the tripping assembly releases the stored energy and drives the arc extinguishing assembly to disconnect, realizing arc extinguishing protection. If an overshoot or jamming fault occurs during energy storage, energy storage can be stopped and the equipment can be switched to a non-energy storage state. Rotating the adjusting component changes the rotation direction, and adjusting the energy storage position can complete the fault reset.

After maintenance, resetting the adjusting component restores the mechanism to the normal unidirectional energy storage working mode, effectively ensuring the basic energy storage and disconnection function of the circuit breaker. When a fault occurs, the mechanism can be reset without disassembling it, and the batch testing process is eliminated, effectively improving the efficiency of maintenance and performance testing, and ensuring the overall controllability and reliability of the tripping mechanism.

Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1, referring to Figure 1 - Figure 2 The first embodiment of the present invention provides an outdoor AC high-voltage vacuum circuit breaker. This device includes: a support member 1, an operating unit 2 fixedly installed on the support member 1, and an arc extinguishing unit 3 fixedly installed on the support member 1. The support member 1 serves as the load-bearing base of the whole machine and provides an installation and positioning foundation for the operating unit 2 and the arc extinguishing unit 3.

[0033] The control unit 2 includes a device component 21 fixedly installed on the support 1, and a control component 22 fixedly installed on the inner wall of the device component 21. The device component 21 provides encapsulation and protection for the internal components. The control component 22, as the core of the mechanism, relies on the output power of the internal drive component 221 to drive the linkage component 223 to rotate, thereby driving the energy storage component 224 to complete the energy storage operation.

[0034] Furthermore, the arc extinguishing unit 3 includes an arc extinguishing component 31 fixedly installed on the support member 1, and the arc extinguishing component 31 is rotatably connected to the operating component 22; when an abnormal fault occurs in the line voltage, the operating component 22 releases the stored energy and drives the arc extinguishing component 31 to quickly perform the disconnection action through the rotatable connection relationship, thereby realizing arc extinguishing protection.

[0035] During use, when the circuit breaker is storing energy normally, the drive component 221 of the tripping assembly 22 outputs power to drive the linkage component 223 to rotate, which in turn drives the energy storage component 224 to store energy. The adjustment component 226 limits and locks the linkage component 223 to maintain the unidirectional locking state of the energy storage transmission. When the linkage component 223 touches the energy storage sensor 227, it is determined that the energy storage is completed. At this time, the tripping assembly 22 and the arc extinguishing assembly 31 maintain a transmission connection.

[0036] When an abnormal voltage fault occurs, the tripping component 22 releases the stored energy to drive the arc extinguishing component 31 to quickly disconnect, thereby achieving arc extinguishing protection.

[0037] If an overshoot or jamming fault occurs during energy storage, energy storage can be stopped and the equipment switched to a non-energy storage state. The control adjustment component 226 releases the one-way locking constraint on the linkage component 223, and the rotation direction and energy storage position can be changed to complete the fault reset. At the same time, under maintenance and testing conditions, after the control adjustment component 226 is released from the limit, the direction adjustment and free rotation of the energy storage component 224 can be realized, thereby completing the inspection and maintenance of the spring-operated energy storage structure. After maintenance, the control adjustment component 226 is reset to restore the one-way locking limit, and the mechanism can return to the normal one-way energy storage working mode. This can effectively ensure the basic function of the circuit breaker's energy storage breaking. When a fault occurs, the mechanism can be reset without disassembling it, and the batch testing process is eliminated, improving the efficiency of maintenance and performance testing, and ensuring the overall controllability and reliability of the breaking mechanism.

[0038] Example 2, refer to Figure 1 - Figure 11 This is the second embodiment of the present invention, which differs from the first embodiment in that: the equipment assembly 21 includes an equipment box 211 fixedly mounted on the support member 1, a partition plate 212 slidably mounted on the inner wall of the equipment box 211, and a partition plate 213 fixedly mounted on the inner wall of the equipment box 211, and the partition plate 213 is slidably connected to the partition plate 212; the equipment box 211 forms a closed protection for all internal transmission components, which can resist the intrusion of outdoor dust and condensation; the partition plate 213 serves as the mounting base for each moving component of the operating assembly 22, and the partition plate 212 and the partition plate 213 slide together to achieve internal chamber partitioning and isolation; a support rod 225 is fixedly mounted on the equipment box 211, and a circuit breaker sensor 228 is fixedly mounted on the bottom of the support rod 225 for collecting and feeding back the circuit breaker opening signal.

[0039] Compared to Embodiment 1, the further control assembly 22 includes a drive component 221 fixedly mounted on the partition 213, a linkage component 223 rotatably mounted on the drive component 221, an energy storage component 224 fixedly mounted on the linkage component 223, and an energy storage rod 222 rotatably mounted on the output end of the drive component 221, and the energy storage rod 222 is rotatably connected to the partition 213; an energy storage sensor 227 is fixedly mounted on the partition 213 for identifying the energy storage completion status; an adjustment component 226 is rotatably mounted on the partition 213, and the adjustment component 226 is rotatably connected to the partition plate 212. The adjustment component 226 can realize one-way locking and unlocking of the linkage component 223 to meet the different working conditions of normal energy storage, fault reset and maintenance testing.

[0040] Furthermore, the drive component 221 includes a motor 2211 fixedly mounted on the partition 213, a transmission rod 2212 fixedly mounted on the output end of the motor 2211, a drive wheel 2213 fixedly mounted on the outer wall of the transmission rod 2212, and a synchronization chain 2214 meshing with the outer wall of the drive wheel 2213, and the synchronization chain 2214 meshing with the linkage component 223; the motor 2211 outputs torque, which is transmitted to the linkage component 223 via the transmission rod 2212, the drive wheel 2213, and the synchronization chain 2214 to realize the power input for electric energy storage.

[0041] Furthermore, a return spring 2215 is fixedly installed on the inner wall of the transmission rod 2212, and a limit strip 2216 is fixedly installed on the other end of the return spring 2215. The limit strip 2216 is slidably connected to the transmission rod 2212. The limit strip 2216, in conjunction with the return spring 2215, can achieve a unidirectional sliding relationship during electric energy storage and a locking force transmission relationship during manual energy storage.

[0042] Furthermore, the energy storage rod 222 includes a sleeve 2221 rotatably mounted on the outer wall of the transmission rod 2212, a limiting block 2222 fixedly mounted on the inner wall of the sleeve 2221, a rotating collar 2223 fixedly mounted on the outer wall of the sleeve 2221, and a rotating arm 2224 fixedly mounted on the rotating collar 2223. The rotating collar 2223 is rotatably connected to the partition plate 213. The limiting block 2222 and the limiting strip 2216 inside the sleeve 2221 cooperate to pull the rotating arm 2224 to drive the sleeve 2221 to rotate in the opposite direction, thereby realizing manual energy storage operation.

[0043] Furthermore, the linkage 223 includes an energy storage arm 2231 rotatably mounted on the partition 213, a limiting ring 2233 fixedly mounted on the outer wall of the energy storage arm 2231, a ratchet 2234 fixedly mounted on the energy storage arm 2231, and an energy storage wheel 2232 fixedly mounted on the energy storage arm 2231. The energy storage wheel 2232 is meshed with the synchronous chain 2214. The synchronous chain 2214 drives the energy storage wheel 2232 to rotate the energy storage arm 2231. The ratchet 2234 and the adjusting member 226 cooperate to complete one-way locking to prevent reverse energy release after energy storage is completed.

[0044] Furthermore, the energy storage component 224 includes a conical rotating component 2241 fixedly mounted on the energy storage boom 2231, a connecting rod 2242 fixedly mounted on the conical rotating component 2241, a connecting block 2243 rotatably mounted on the outer wall of the connecting rod 2242, an energy storage spring 2244 fixedly mounted on the connecting block 2243, a connecting block 2245 fixedly mounted on the other end of the energy storage spring 2244, and an adjusting shaft 2246 rotatably mounted on the bottom of the connecting block 2245. The adjusting shaft 2246 is fixedly connected to the equipment box 211. When the energy storage boom 2231 rotates, it drives the energy storage spring 2244 to compress and store energy. When a line fault occurs, the energy storage spring 2244 releases potential energy to output disconnection power.

[0045] Furthermore, a limiting sliding wheel 2249 is fixedly installed on the connecting rod 2242, and the limiting sliding wheel 2249 is slidably connected to the support rod 225 and the trip sensor 228; a rotating shaft 2247 is rotatably installed on the connecting rod 2242, and a linkage rod 2248 is fixedly installed on the rotating shaft 2247, and the linkage rod 2248 is rotatably connected to the arc extinguishing assembly 31. When the mechanism performs the tripping action, the limiting sliding wheel 2249 triggers the trip sensor 228 to feed back the tripping signal, and the linkage rod 2248 transmits the tripping driving force to the arc extinguishing assembly 31.

[0046] Furthermore, the adjusting component 226 includes an adjusting rod 2261 rotatably mounted on the partition 213, a rotating rod 2262 engaged with the adjusting rod 2261, a limiting ring 2263 fixedly mounted on the outer wall of the rotating rod 2262, a ratchet disc 2264 fixedly mounted on the outer wall of the rotating rod 2262, a locking plate 2265 rotatably mounted on the inner wall of the ratchet disc 2264, a spring plate 2266 fixedly mounted on the locking plate 2265, and a connecting block 2267 fixedly mounted on the other end of the spring plate 2266. The connecting block 2267 is fixedly connected to the ratchet disc 2264. During normal energy storage, the spring plate 2266 pushes the locking plate 2265 to engage the ratchet mechanism 2234 to achieve one-way locking; rotating the adjusting rod 2261 can drive the ratchet disc 2264 to rotate, causing the locking plate 2265 to disengage from the ratchet mechanism 2234 and release the lock, thereby realizing fault reset and mechanism idle test. After reset, the one-way locking state can be restored.

[0047] During use, the equipment component 21 first relies on the equipment box 211 to form a closed protection for all internal transmission parts, resisting the interference of dust and condensation in the outdoor environment; the partition 213 serves as the main mounting base for the moving parts of the control component 22, and the partition plate 212 and the partition plate 213 slide together to achieve internal chamber partitioning and isolation; the support rod 225 is fixedly arranged with the circuit breaker sensor 228, which is used to collect and feedback the circuit breaker opening signal.

[0048] During normal energy storage operation, the motor 2211 inside the drive component 221 outputs power, which is transmitted to the torque via the transmission rod 2212, drive wheel 2213, and synchronous chain 2214, driving the energy storage wheel 2232, energy storage arm 2231, and ratchet 2234 of the linkage component 223 to rotate synchronously. The energy storage arm 2231 drives the energy storage component 224 to move, compressing the energy storage spring 2244 to complete the closing and energy storage. During this process, the pawl disc 2264 and the locking plate 2265 inside the adjusting component 226 abut against and engage the ratchet 2234 under the elastic force of the spring plate 2266, limiting and locking the linkage component 223 to achieve one-way locking, preventing the ratchet 2234 from rotating in the opposite direction after energy storage is completed and causing the spring to release energy unexpectedly. When the linkage component 223 rotates and contacts the energy storage sensor 227, the system determines that the spring has finished storing energy, and the mechanism enters the waiting-to-open state.

[0049] When the motor 2211 drives the transmission rod 2212 to rotate and store energy, the transmission rod 2212 rotates inside the sleeve 2221. Relying on the irregular structure of the limiting strip 2216 inside the transmission rod 2212 and the limiting block 2222 on the inner wall of the sleeve 2221 (one side rounded, one side right angle), the limiting strip 2216 can compress the return spring 2215 and slide it relative to the limiting block 2222 in one direction, thus realizing power transmission under motor-driven energy storage. When manual energy storage is required, pulling the rotating arm 2224 causes the rotating collar 2223 to drive the sleeve 2221 and the limiting block 2222 to rotate in the opposite direction. The limiting block 2222 engages with the limiting strip 2216 in the opposite direction, thereby driving the transmission rod 2212 to rotate synchronously, completing manual energy storage.

[0050] When an abnormal voltage fault occurs in the line, the energy storage spring 2244 quickly releases its elastic potential energy. The power is output outward through the conical rotating part 2241, the connecting power through the connecting rod 2242, and the linkage rod 2248, driving the arc extinguishing component 31 to perform a rapid disconnection operation. After the disconnection and arc extinguishing are completed, the limit sliding wheel 2249 on the connecting rod 2242 touches the trip sensor 228 and outputs a trip completion signal.

[0051] If energy storage overshoot or transmission jamming occurs during the energy storage process, first cut off the power output of the drive component 221 to switch the equipment to the non-energy storage state. Then, manually operate the adjusting rod 2261 of the adjusting component 226, which drives the ratchet plate 2264 to rotate through the rotating rod 2262. This causes the locking plate 2265 to overcome the elastic force of the spring plate 2266 and disengage from the ratchet component 2234. After releasing the one-way locking constraint, the mechanism can be manually rotated to achieve the energy storage position retraction and reset. During whole machine maintenance and performance testing, the locking can also be released by operating the adjusting component 226 in the same way, allowing the energy storage component 224 to achieve steering adjustment and idling, facilitating assembly verification and fault diagnosis. After maintenance and debugging are completed, reset the adjusting component 226. The spring plate 2266 will push the locking plate 2265 to engage and lock the ratchet component 2234 again, restoring the mechanism to the original working mode of one-way energy storage locking.

[0052] This structure, with the help of equipment box 211, is adapted to harsh outdoor working conditions. It collects the operating status of the mechanism in real time through energy storage sensor 227 and circuit breaker sensor 228. It is compatible with both electric and manual energy storage methods. It can stably realize the basic protection functions of circuit breaker energy storage and rapid fault disconnection. In the event of a fault, it can be reset without disassembling parts. During the testing phase, it eliminates the batch testing process, effectively improving the efficiency of assembly, debugging and fault repair. After debugging, it can completely restore the original unidirectional transmission logic, taking into account both the convenience of operation and the safety of equipment operation, and ensuring the overall controllability and reliability of the operating mechanism.

[0053] The remaining structure is the same as that in Example 1.

[0054] Example 3, referring to Figure 1 - Figure 12 This is the third embodiment of the present invention, which differs from the second embodiment in that: the arc extinguishing assembly 31 includes a support base 311 fixedly installed on the inner wall of the support member 1, an arc extinguishing tube 312 fixedly installed on the support base 311, a connecting tube 313 fixedly installed on the arc extinguishing tube 312, a trigger rod 314 fixedly installed on the inner wall of the connecting tube 313, a buffer member 318 fixedly installed on the support base 311, a connecting base 317 fixedly installed on the buffer member 318, and a transmission rod 315 fixedly installed on the connecting base 317. The trigger rod 314 is slidably connected to the support base 311, which serves as the overall load-bearing base and positions and installs components such as the arc-extinguishing tube 312. The arc-extinguishing tube 312 and the connecting pipe 313 together form the arc-extinguishing channel for cooling and extinguishing the electric arc. During normal closing, the transmission rod 315 presses the trigger rod 314 to maintain the closed and conductive contact inside the arc-extinguishing tube 312. During fault opening, the transmission rod 315 retracts to release the trigger rod 314, the contacts separate to generate an electric arc, and the arc is extinguished in the arc-extinguishing channel. The buffer 318 is used to absorb the opening impact caused by the high-speed movement of the connecting base 317 and reduce the vibration and wear of the components.

[0055] Compared to Embodiment 2, the connecting seat 317 is further equipped with a second connecting rod 319, which is rotatably connected to the linkage rod 2248. A sealing element 316 is fixedly installed on the inner wall of the arc-extinguishing tube 312, and the sealing element 316 is slidably connected to the transmission rod 315. The second connecting rod 319 realizes the power transmission between the operating component 22 and the arc-extinguishing component 31. When closing, the linkage rod 2248 pushes the connecting seat 317 through the second connecting rod 319. When opening, the connecting seat 317 is pulled to drive the transmission rod 315 back. After the fault is eliminated, the transmission is reset with the energy storage mechanism. The sealing element 316 and the transmission rod 315 slide to form a dynamic seal, preventing outdoor water vapor and dust from entering the interior of the arc-extinguishing tube 312, ensuring the arc-extinguishing chamber is sealed and ensuring the reliability of the arc-extinguishing operation.

[0056] During use, the arc extinguishing component 31 is first installed on the support base 311 and rotatedly connected to the linkage rod 2248 of the operating component 22. Under normal closing conditions, the operating component 22 completes energy storage. The linkage rod 2248 keeps the connecting base 317 in a limited position through the connecting rod 319, so that the transmission rod 315 continuously presses the trigger rod 314. The internal contacts of the arc extinguishing tube 312 remain in a closed and conductive state. The sealing element 316 fits against the transmission rod 315 to make a sliding seal, preventing external moisture and dust from entering the interior of the arc extinguishing tube 312 and maintaining a sealed working environment of the arc extinguishing chamber.

[0057] When a short circuit, overvoltage, or other voltage abnormality fault occurs in the line, the energy storage spring 2244 of the tripping component 22 instantly releases the stored elastic potential energy. The power is transmitted sequentially through the conical rotating part 2241 and the first connecting rod 2242 to the linkage rod 2248. The linkage rod 2248 pulls the second connecting rod 319, causing the connecting seat 317 to move rapidly. The connecting seat 317 causes the transmission rod 315 to retract backward, releasing the pressure constraint on the trigger rod 314. The moving and stationary contacts inside the arc extinguishing tube 312 quickly separate and generate a high-temperature arc. The arc is extinguished by arc extinguishing. The arc-extinguishing channel formed by pipe 312 and connecting pipe 313 is cooled and elongated to extinguish the arc, thereby completing the disconnection of the faulty line. During this process, the buffer component 318 buffers and unloads the high-speed tripping impact of the connecting seat 317, absorbs mechanical impact energy, and reduces the vibration and wear of each transmission component. After the entire tripping action is completed, the limit sliding wheel 2249 on the connecting rod 2242 slides along the support rod 225 and touches the tripping sensor 228, outputting an electrical signal indicating that the tripping is complete, which is then collected by the background system to monitor the circuit breaker status.

[0058] After the line fault is cleared, the operating component 22 resumes electric or manual energy storage. The linkage rod 2248 moves in the opposite direction with the mechanism, pushing the connecting rod 319, connecting seat 317, and transmission rod 315 to reset in sequence. The transmission rod 315 presses the trigger rod 314 again, and the internal contacts of the arc extinguishing tube 312 close again, restoring the circuit breaker to closing and conducting, effectively protecting the safety of the power distribution line. The buffer component weakens the tripping impact and extends the service life of the components. The sealed structure is suitable for complex outdoor working conditions. The entire transmission link is simple and reliable. With the help of the sensor, the tripping status feedback is realized. After the fault is cleared, it can be reset with the operating mechanism, helping the power supply line to be quickly restored.

[0059] The remaining structure is the same as that in Example 2.
