[0002] Fault-finding deep-fusion circuit breakers are a new type of equipment in power systems that integrates fault isolation, location, and intelligent control. Through deep integration of primary and secondary equipment and traveling wave ranging technology, they achieve efficient and precise fault handling. These circuit breakers embed components such as traveling wave ranging modules, high-precision sensors, and intelligent control units into the switch body, enabling real-time acquisition of traveling wave, transient, and power frequency signals. Combined with BeiDou clock synchronization technology (accuracy ≤0.1μs), they achieve precise fault location within hundreds of meters.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the second motor in the moving component drives the driven wheel via a bevel gear kit, which, in conjunction with the track with an internal toothed structure, enables the circuit breaker to automatically move to the detection area without manual intervention, improving the flexibility and efficiency of detection. Upon arrival, the telescopic component operates, with the first motor driving the transmission rod via a crank-connecting rod mechanism, pushing the telescopic connecting rod frame of the cross-hinged joint to extend and retract, adjusting the position of the detection component so that the arc-shaped detector on the arc plate is precisely close to the line and the spacing and posture are adjusted, improving the detection accuracy.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Refer to Figure 1 - Figure 4 As shown: In this embodiment, a fault-finding deep fusion circuit breaker is included, comprising a telescopic assembly 1, which includes a mounting housing 101, a first motor 102, a connecting rod 103, a movable rod 104, a transmission rod 105, and a telescopic linkage frame 106. The first motor 102 is mounted on the mounting housing 101, and its output end is connected to the connecting rod 103. The connecting rod 103 is connected to the movable rod 104, and the movable rod 104 is connected to the transmission rod 105. The transmission rod 105 is connected to the telescopic linkage frame 106. A moving assembly 2 is also included. The system includes two motors 201, a first bevel gear assembly 202, a second bevel gear assembly 203, a driven wheel 204, and a track 205. The output end of the second motor 201 is connected to the first bevel gear assembly 202. The first bevel gear assembly 202 meshes with the second bevel gear assembly 203. The second bevel gear assembly 203 is connected to the driven wheel 204. The track 205 cooperates with the driven wheel 204. The system also includes a detection component 3, which includes an arc plate 301 and an arc detector 302. The arc detector 302 is mounted on the arc plate 301 and the detection component 3 is connected to the telescopic component 1.

[0026] The effect achieved by the entire embodiment 1 is as follows: the second motor 201 outputs power to drive the first bevel gear assembly 202 to rotate. Since the first bevel gear assembly 202 meshes with the second bevel gear assembly 203, the power is transmitted to the second bevel gear assembly 203, which in turn drives the driven wheel 204 to rotate. The driven wheel 204 cooperates with the track 205 (which has a toothed structure on its inner side that meshes with the driven wheel 204), causing the track 205 to rotate and drive the entire circuit breaker device to automatically move to the designated line detection area. No manual handling is required, and it can quickly adapt to multi-section detection of long-distance lines. This greatly improves the flexibility and efficiency of the detection process. After reaching the detection position, the telescopic component 1 begins to work: the first motor 102 starts, and its output end drives the connecting rod 103 to rotate. The connecting rod 103 converts the rotation into the linear reciprocating motion of the movable rod 104 through a crank-connecting rod mechanism. The movable rod 104 drives the transmission rod 105 to move, thereby pushing the telescopic connecting rod frame 106, which is composed of multiple cross-hinged connecting rods, to extend or retract (the end of the transmission rod 105 is connected to the cross-hinged connection of the connecting rod frame, which can change the extension range). This adjusts the position of the detection component 3, allowing the arc plate 301 to move. The arc-shaped detector 302 is precisely positioned close to the power line to be tested. It can flexibly adjust the spacing and posture of the detection component 3 according to the spatial position of the line to ensure that the arc-shaped detector 302 and the line are in the best detection state, thereby improving the detection accuracy. Subsequently, the detection component 3 plays its role: the arc-shaped detector 302 (as a sensor for detecting current traveling wave signals) embedded in the inner arc surface of the arc plate 301 can capture the current traveling wave signal in the line in real time after the telescopic component 1 is adjusted to the correct position (a characteristic traveling wave will be generated when a fault occurs). The arc surface design of the arc plate 301 can increase the sensing area with the line, receive signals more comprehensively, and reduce omissions. By analyzing parameters such as the propagation time and amplitude of the traveling wave, fault location is achieved. Overall, the moving component 2 allows the device to flexibly cover a wide area of ​​lines, the telescopic component 1 can precisely adjust the detection posture, and the detection component 3 can efficiently capture fault signals. This not only improves the autonomy and efficiency of fault location, but also reduces the problem of electronic system interference through mechanical structure linkage. It can work stably in complex power environments, providing reliable support for the rapid location and isolation of distribution network faults, effectively shortening the fault handling time and improving power supply reliability.

[0027] Example 2: According to Figure 1 - Figure 4As shown: The telescopic linkage frame 106 is composed of multiple cross-hinged linkages. The end of the transmission rod 105 is connected to the cross-hinged joint of the telescopic linkage frame 106. The first bevel gear assembly 202 includes a first bevel gear and a second bevel gear that mesh with each other. The output end of the second motor 201 is connected to the first bevel gear. The second bevel gear is connected to the second bevel gear assembly 203. The second bevel gear assembly 203 includes a third bevel gear and a fourth bevel gear that mesh with each other. The third bevel gear is connected to the first bevel gear assembly 202, and the fourth bevel gear is connected to the driven wheel 20. The shaft of 4 is connected, and the inner side of the track 205 is provided with a toothed structure that meshes with the driven wheel 204. The arc detector 302 is a sensor used to detect the current traveling wave signal, and the arc detector 302 is embedded in the inner arc surface of the arc plate 301. The mounting shell 101 is a hollow cuboid structure, and the bottom of the mounting shell 101 is connected to the moving component 2. The connecting rod 103 is connected to the movable rod 104 through a crank-connecting rod mechanism, so that when the first motor 102 drives the connecting rod 103 to rotate, it drives the movable rod 104 to perform linear reciprocating motion.

[0028] The overall effect of the second embodiment is as follows: the second motor 201 starts, and its output end drives the first bevel gear in the first bevel gear assembly 202 to rotate. Since the first bevel gear and the second bevel gear mesh with each other, the power is transmitted to the second bevel gear, which in turn drives the third bevel gear in the second bevel gear assembly 203 to rotate. The third bevel gear meshes with the fourth bevel gear, so the fourth bevel gear rotates and drives the shaft of the driven wheel 204 to rotate. Since the inner side of the track 205 is provided with a toothed structure that meshes with the driven wheel 204, the driven wheel 204 rotates and drives the track 205 to rotate. The mounting shell 101 is a hollow cuboid and its bottom is connected to the moving component 2, so it can move with the track. Track 205 moves and carries the telescopic assembly 1 and detection assembly 3 to the area to be inspected. This design of vertical transmission with bevel gears and track 205 adapts to complex outdoor terrain and ensures stable power transmission through gear meshing. It can quickly and accurately reach the inspection point without manual handling, greatly improving the flexibility of inspection. Then, the telescopic assembly 1 starts to work: the first motor 102 drives the connecting rod 103 to rotate. Since the connecting rod 103 is connected to the movable rod 104 through a crank-connecting rod mechanism, the rotation of the connecting rod 103 is converted into the linear reciprocating motion of the movable rod 104. The movable rod 104 drives the transmission rod 105 to move. The end of the transmission rod 105 is connected to a multi-linkage mechanism. The telescopic linkage 106, composed of cross-hinged rods, is connected at its cross-hinged joints, thereby extending or retracting the telescopic linkage 106 to adjust the position and orientation of the detection component 3. Finally, the detection component 3 comes into play: the arc-shaped detector 302 is a sensor for detecting current traveling wave signals and is embedded in the inner arc surface of the arc-shaped plate 301. When the telescopic component 1 is adjusted to the correct position, the arc surface of the arc plate 301 can better fit the power line, increasing the sensing area and allowing the arc detector 302 to more comprehensively capture the current traveling wave signals in the line (especially during faults). By analyzing parameters such as the propagation time and amplitude of the traveling wave, fault location can be achieved. Overall, the movement... Component 2, relying on bevel gear transmission and track 205, achieves flexible movement and stable power transmission, allowing the device to quickly reach the detection area. Telescopic component 1, through crank-connecting rod mechanism, drives telescopic connecting rod frame 106 to precisely adjust the position of detection component 3, ensuring detection accuracy. Detection component 3, through its arc design and embedded sensors, efficiently captures fault signals. The linkage of these three components not only improves the automation and efficiency of fault location but also reduces the possibility of interference to the electronic system through precise transmission of the mechanical structure. It works stably in complex power environments, providing reliable support for rapid fault location and isolation in the distribution network, effectively shortening fault handling time and improving power supply reliability.

[0029] Working principle: When power line fault detection is carried out, the moving component 2 starts operating first: the second motor 201 outputs power, which drives the first bevel gear in the first bevel gear kit 202 to rotate. Because the first bevel gear meshes with the second bevel gear in the kit, the power is smoothly transmitted to the second bevel gear, which then drives the third bevel gear in the second bevel gear kit 203 to rotate. The third bevel gear meshes with the fourth bevel gear in the same kit, causing the fourth bevel gear to rotate synchronously and drive the shaft of the driven wheel 204 to rotate. Since the inner side of the track 205 has a toothed structure that meshes with the driven wheel 204, the rotation of the driven wheel 204 drives the track 205 to run stably. The mounting shell 101 is a hollow cuboid structure, and its bottom is connected to the moving component. 2. Fixed connection, capable of carrying the telescopic component 1 and detection component 3 along with the movement of the track 205, ultimately enabling the entire circuit breaker device to automatically reach the designated line detection area. This design, which achieves vertical transmission through bevel gears in conjunction with the track 205, can adapt to complex outdoor terrain and ensures the stability of power transmission through gear meshing. It allows the device to quickly and accurately reach the detection point without manual handling, greatly improving detection flexibility and adaptability to multi-section detection of long-distance lines. Upon reaching the detection position, the telescopic component 1 immediately starts working: the first motor 102 starts, and its output drives the connecting rod 103 to rotate. Because the connecting rod 103 is connected to the movable rod 104 through a crank-connecting rod mechanism, the rotation of the connecting rod 103 is controlled by the rotation of the connecting rod. The linear reciprocating motion of the movable rod 104 causes the transmission rod 105 to move synchronously. The end of the transmission rod 105 is connected to the cross-hinged joint of the telescopic linkage frame 106, which is composed of multiple connecting rods. This causes the telescopic linkage frame 106 to extend or retract, thereby flexibly adjusting the position and orientation of the detection component 3. This ensures that the arc detector 302 on the arc plate 301 can accurately approach the power line to be tested and can flexibly adjust the spacing and orientation of the detection component 3 according to the spatial position of the line. This keeps the arc detector 302 in the optimal detection state with the line, effectively improving the detection accuracy. Subsequently, the detection component 3 begins to perform its fault detection function: the arc detector 302 is a transmission rod specifically designed for detecting current traveling wave signals. The sensor is embedded in the inner arc surface of the arc plate 301. After the telescopic component 1 completes its position adjustment, the arc surface design of the arc plate 301 can increase the sensing area with the power line, allowing the arc detector 302 to more comprehensively receive the current traveling wave signal in the line (especially the characteristic traveling wave generated when a fault occurs), reducing signal loss. By analyzing key parameters such as the propagation time and amplitude of the traveling wave, accurate fault location can be achieved. Overall, the moving component 2, relying on the cooperation of bevel gear transmission and track 205, realizes the flexible movement and stable power transmission of the device, ensuring its rapid arrival at the detection area. The telescopic component 1, through the crank-connecting rod mechanism, drives the telescopic connecting rod frame 106 to precisely adjust the position and attitude of the detection component 3, ensuring detection accuracy.The detection component 3, through the arc-shaped plate 301 and the embedded arc-shaped detector 302, efficiently captures fault traveling wave signals. The coordinated operation of these three components significantly improves the automation and efficiency of fault location, and the precise transmission of the mechanical structure reduces the possibility of interference with the electronic system. This enables the device to operate stably in complex power environments, providing reliable support for rapid fault location and isolation in distribution networks, effectively shortening fault handling time and improving power supply reliability.
