Description

Technical Field

[0001] The present invention relates to the technical field of power grid monitoring, and in particular to a device for accurately locating distributed faults in power transmission lines. Background Art

[0002] During the operation of the transmission line, due to various reasons, including weather factors, load trends, performance of equipment after being put into operation, malicious human damage, etc., the transmission line may fail, affecting the stable operation of the power grid. Therefore, it is particularly important to quickly and accurately locate the fault point to ensure the safe operation of the power grid. The ordinary transmission line fault location method is usually a single location, which cannot quickly locate the fault point and cannot monitor the line status in real time. The distributed fault location device based on the Internet of Things technology can accurately locate the fault by collecting and processing line fault signals. The distributed fault location device adopts the Internet of Things technology and wireless communication technology. Through the distributed deployment of monitoring terminals, it can capture the instantaneous traveling wave signal of the fault at close range and regularly collect the operation status of the power grid. When a fault occurs, the fault point can be located in time and accurately according to the monitoring data provided by the remote monitoring system to ensure the stable operation of the power grid.

[0003] After the existing distributed fault precise positioning device of the transmission line is installed on the cable, when the maintenance personnel move the pulley basket on the cable to inspect the line, the fault monitoring and positioning device will hinder the movement of the pulley basket. Therefore, it is necessary to remove the monitoring and positioning device from the cable and reinstall it after the pulley basket passes over, which is troublesome and inconvenient for the regular maintenance of the cable. Summary of the invention

Through the setting of the clamping mechanism, when the pulley basket moves on the cable, the pulley rolls and moves on the cable. When the pulley rolls close to the device, the pulley squeezes and pushes the rocker arm to deflect toward the middle position. After the pulley pushes the rocker arm to deflect to a certain angle, the rocker arm actively deflects away from the pulley, thereby causing the rocker arm to disengage from the wheel groove portion of the pulley, and the clamping component 2 disengages from the clamping component 1. The movable shell component 1 and the movable shell component 2 are flipped and unfolded to both sides, and the pulley is rolled over the throat hoop, thereby smoothly passing over the device and continuing to move on the cable, and the movable shell component 1 and the movable shell component 2 are closed and clamped upward to complete the reassembly, so that the device is easy to operate when it is closed after being unfolded, and the pulley basket passes over the device during maintenance.

When the round wheel 234 passes the vertex 232 of the curved plate 231, the wheel seat 233 actively moves to the right under the action of the extrusion spring 237, so that the pull rod 210 moves to the right, thereby actively pulling the rocker arm 220 to deflect to the right through the insertion rod 212, so that after the pulley pushes the rocker arm 220 to deflect to the middle position, the rocker arm 2 20 actively deflects away from the pulley, so that the rocker arm 220 is separated from the wheel groove of the pulley, which facilitates the subsequent opening of the movable shell 110 and the movable shell 2 120 to both sides. The middle position of the inner wall of the mounting groove 121 is fixedly connected with the pop-up module 240, and the pop-up module 240 includes a slide bar 245, and the slide bar 245 is fixedly connected to the inner wall of the mounting groove 121.

When the connecting rod 242 pushes the push block 244 on the left to move left, the rocking plate 253 pushes the baffle 213 to the right, so that the pull rod 210 The rod 210 moves to the left until the round wheel 234 passes the apex 232 of the curved plate 231 to the left, and the push block 244 moves to the right until the round rod 255 moves to the transition portion 254, and the rocking plate 253 deflects downward, so that the rocking plate 253 is out of contact with the baffle 213, thereby preventing the rocking plate 253 from blocking the rightward movement of the baffle 213 when the device is opened, and facilitating the rightward movement of the push block 244 when it moves to the right to drive the pull rod 210. A sliding groove 221 is provided on one side wall of the rocker arm 220, and one end of the insertion rod 212 is slidably connected to the inner wall of the sliding groove 221. One end of the rocker arm 220 is rotatably connected to a roller to reduce the friction between the rocker arm 220 and the pulley on the hanging basket, and facilitate the deflection of the rocker arm 220.

[0031] Both ends of the second mounting groove 121 are fixedly connected with a vertical shell 122, and the vertical shell 122 is used to shield the other end of the rocker arm 220. The plug rod 212 is slidably plugged into the vertical shell 122. Opening grooves for avoiding the rocker arm 220 are opened at both ends of the mobile shell 120. The vertical shell 122 is used to shield the opening grooves at both ends of the mobile shell 120 to reduce the entry of external rainwater from the opening grooves. The cross-sections of the intermediate shell 100, the mobile shell 1 10 and the mobile shell 2 120 are all arc-shaped, which facilitates the intermediate shell 100, the mobile shell 1 10 and the mobile shell 2 120 to be combined into a cylindrical shape and fixed on the cable, and the fan angle of the intermediate shell 100 is less than sixty degrees to avoid interference between the intermediate shell 100 and the hanging basket pulley. The outer walls of the mobile shell 1 10 and the mobile shell 2 120 are embedded and fixed with photovoltaic panels, which are used to drive the detection module, the positioning module and the signal transmission module 102.

[0032] Working principle: When in use, place the intermediate shell 100 under the cable, bind the throat clamp 103 to the cable and tighten it, close the movable shell 110 and the movable shell 2 120, and clamp the clamp 1 112 and the adjacent clamp 2 211, so that the intermediate shell 100, the movable shell 1 110 and the movable shell 2 120 are combined into a cylindrical shape and fixed on the cable. The current on the cable flows through the throat clamp 103 and passes through the detection module. The detection module checks the current on the cable and sends the detection data to the server through the signal transmission module 102;

[0033] During the maintenance process, when the pulley basket moves on the cable, the pulley rolls on the cable. When the pulley rolls close to the device, the pulley squeezes and pushes the rocker arm 220 to deflect toward the middle position, so that the rocker arm 220 pushes the pull rod 210 to move toward the middle through the insertion rod 212, and the pull rod 210 drives the wheel seat 233 to move to the right through the fixed plate 236. When the round wheel 234 passes the vertex 232 of the curved plate 231, the wheel seat 233 actively moves to the right under the action of the squeezing spring 237, thereby making the pull rod 210 move to the right. When the pull rod 210 moves to the right, the rocker arm 220 is actively pulled to deflect to the right by the insertion rod 212, so that after the pulley pushes the rocker arm 220 to deflect to the middle position, the rocker arm 220 actively deflects away from the pulley, so that the rocker arm 220 is separated from the wheel groove of the pulley. When the pull rod 210 moves to the right, it drives the second clamping member 211 to separate from the first clamping member 112, and the pop-up module 130 and the pop-up module 240 pop out from each other, so that the mobile shell 110 and the mobile shell 2 120 are turned over and unfolded to both sides, and the pulley rolls over the throat hoop 103. After the pulley passes over the device, the moving shell 110 and the moving shell 2 120 are manually deflected upward and closed at the same time, and the pop-up module 130 and the pop-up module 2 240 are in contact and squeezed, so that the spring telescopic rod 243 contracts, thereby pushing the push block 244 on the left to move left through the connecting rod 242, and the rocking plate 253 pushes the baffle 213 to the right, so that the pull rod 210 moves left, until the round wheel 234 passes the vertex 232 of the curved plate 231 to the left, and the push block 244 moves right to the round rod 255 and moves to the transition part 254 When the device is opened, the rocking plate 253 deflects downward, so that the rocking plate 253 is out of contact with the baffle 213, thereby preventing the rocking plate 253 from blocking the rightward movement of the baffle 213 when the device is opened. After the clamp 1 12 and the clamp 2 211 are interlaced, the clamp 2 211 moves rightward and engages with the clamp 1 112 under the elastic force of the extrusion spring 237, so that the movable shell 1 110 and the movable shell 2 120 are closed and engaged, completing the reassembly, making the device easy to operate when unfolding and closing, and facilitating the pulley basket to pass over the device during maintenance.
