Description

Technical Field

[0001] This invention relates to the field of operation and maintenance operating system technology, specifically to an operation and maintenance operating system for a power distribution automation terminal box and its usage method. Background Technology

[0002] Distribution automation terminal boxes are key equipment in distribution automation systems, primarily used for monitoring, controlling, and protecting distribution networks. They are typically installed at critical nodes in distribution lines, such as switching stations, ring main units, and pole-mounted switches, enabling real-time monitoring and remote operation of the distribution network. Distribution automation terminal boxes are widely used in the automated management of distribution networks, providing automated control and monitoring for distribution systems. A distribution automation terminal is a distributed control and monitoring device used in power systems, typically including multiple functional modules such as metering, protection, control, communication, and a human-machine interface.

[0003] A power distribution automation terminal box operation and maintenance device, disclosed in Chinese patent application number CN 117277119 A, includes a telescopic assembly connected to a clamping assembly via an angle adjustment connection assembly. The telescopic assembly has a control unit electrically connected to the clamping assembly. The clamping assembly comprises a bushing, an automatic clamping part, and an auxiliary linkage part. The auxiliary linkage part is rotatably mounted on the bushing, and the automatic clamping part is installed at the front end of the auxiliary linkage part. A clamping bar is suspended on the auxiliary linkage part. Manually driving the clamping bar to raise or lower the auxiliary linkage part causes it to rotate, which in turn drives the automatic clamping part to rotate. This device enables flexible plugging and unplugging of network cables and serial cables through a mechanical mechanism, allowing for basic opening and closing operations of the terminal box without the need for climbing.

[0004] However, in actual use, users still need to go to the location of the power distribution automation terminal box, open the box door to perform maintenance operations, and check the internal wiring of the power distribution automation terminal box.

[0016] Optionally, a locking mechanism is provided inside one side of the power distribution automation terminal box body. The locking mechanism includes a first limiting block, a limiting rod, a support spring, a second limiting block, and a lever. The first limiting block is fixedly installed on one side of the movable door. One end of the movable door has a movable groove corresponding to the first limiting block.

[0019] A method for using the operation and maintenance operating system of a power distribution automation terminal box includes the following steps:

[0020] S1: During the operation and maintenance of the power distribution automation terminal box, the control box is first opened and the control host is operated through the control panel. The camera captures the internal image of the power distribution automation terminal box and displays it through the control host. When a certain line inside the power distribution automation terminal box needs to be detected, the electric push rod extends to make the snap-fit ​​part snap into the snap-fit ​​groove. When the mounting cylinder cannot rotate, the first servo motor is controlled to drive the guide rod with threaded groove to rotate. The guide rod with threaded groove meshes with the threaded hole inside the mounting cylinder, so that the sliding frame slides up and down inside the power distribution automation terminal box. The third servo motor can be used to control the rotation of the shaft, thereby controlling the rotation of the gear. By controlling the rotation of the gear, the gear can mesh with the rack to adjust the position of the moving frame on the side wall of the sliding frame. The fourth servo motor can be used to control the rotation of the second threaded rod, thereby adjusting the position of the movable frame on one side of the movable frame, so that the current transformer core inside the movable frame can better clamp and detect the line.

[0021] S2: By adjusting and moving the current transformer core to the side of the line to be tested, the fifth servo motor can be used to control the rotation of the mounting shaft. The rotation of the mounting shaft can be used to control the rotation of one of the current transformer cores. When one current transformer core rotates, it can drive the other current transformer core to rotate in the opposite direction at the same time through the teeth and grooves, thereby achieving the clamping of the two current transformer cores, so that the line is located on the side of the secondary winding of the current transformer inside the current transformer core. If the ammeter reading is zero, it means that there is no leakage in the line. If the ammeter reading is not zero, it means that there is leakage in the circuit. The wireless connection module is connected to the wireless connector. By setting the wireless connection module, the ammeter can be connected to the central processing unit in the control host through the wireless connector, so that the detection data can be transmitted to the control host, and the detection situation can be directly observed.

[0022] S3: When the production line malfunctions and requires maintenance, the movable door is opened. When the movable door is opened, the first limit block will first contact the second limit block inside the movable groove, pushing the second limit block into the movable cavity. Then, the second limit block pops out under the support of the support spring, locking the first limit block in the movable groove, preventing the movable door from closing. This fixes the position of the movable door after it is opened, preventing the movable door from rotating randomly after it is opened, which would affect the operator's operation.

[0023] This invention has at least the following beneficial effects:

[0024] (1) This solution sets up an operation and maintenance organization and a remote control organization. During the operation and maintenance process, the operation and maintenance personnel operate the operation and maintenance organization through the control host, observe the internal situation of the power distribution automation terminal box through the camera, and make the sliding frame slide up and down inside the power distribution automation terminal box through the rotation of the guide rod. Then, through the rotation of the gear, the movable frame can move laterally inside the power distribution automation terminal box. Then, through the rotation of the second threaded rod, the distance between the movable frame and the moving frame can be adjusted, thereby adjusting the distance between the transformer core and the wire inside the power distribution automation terminal box. This allows the transformer core to be clamped and tested more accurately inside the power distribution automation terminal box. During the test, it is not necessary to open the power distribution automation terminal box, making the entire operation and maintenance test process more time-saving and labor-saving, and making operation and maintenance more convenient and efficient.

[0025] (2) This solution sets up a snap-fit ​​mechanism. When the movable door is opened, the first limit block will first contact the second limit block inside the movable groove, pushing the second limit block into the movable cavity. Then, the second limit block pops out under the support of the support spring, and snaps the first limit block into the movable groove, so that the movable door cannot be closed. This fixes the position of the movable door after it is opened, and prevents the movable door from rotating randomly after it is opened, which would affect the operator's operation.

[0026] (3) This solution can be used to control the movement of the snap-fit ​​component by setting an electric push rod. The snap-fit ​​component can be snapped into the snap-fit ​​groove by moving, and the rotation of the mounting cylinder can be controlled. When the mounting cylinder cannot rotate, the guide rod with the threaded groove can rotate to drive the sliding frame to move. When the mounting cylinder can rotate, the sliding frame can quickly move to the bottom of the guide rod and quickly move to the bottom of the power distribution automation terminal box body to achieve the effect of quick reset.

[0027] (4) This scheme can control the rotation of the first threaded rod by setting a second servo motor. The rotation of the first threaded rod can be used to control the movement of the slider inside the adjustment groove, thereby controlling the position of the camera and making the observation more comprehensive.

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-12 This invention provides an operating system and usage method for the operation and maintenance of a power distribution automation terminal box, including:

[0045] The power distribution automation terminal box body 1 has a rotating movable door 101 installed inside the power distribution automation terminal box body 1. The movable door 101 is engaged with the power distribution automation terminal box body 1 by a latch.

[0046] The operation and maintenance organization is installed inside the main body 1 of the power distribution automation terminal box. The operation and maintenance organization moves and adjusts the position of the two current transformer cores 33 by sliding frame 3 and moving frame 31, and then uses ammeter 331 in conjunction with the two current transformer cores 33 to detect the line current inside the main body 1 of the power distribution automation terminal box to understand the operation status of the main body 1 of the power distribution automation terminal box.

[0047] The remote control mechanism is installed at the bottom of the power distribution automation terminal box 1 and inside the power distribution automation terminal box 1. The remote control mechanism remotely controls the operation and maintenance mechanism through the control host 201.

[0048] In some embodiments, see Figure 6 , Figure 7The operation and maintenance mechanism includes a guide rod 131, a rack 301, a movable frame 32, a rotating shaft 313, a gear 314, and a second threaded rod 315. A sliding groove 13 is provided inside the main body 1 of the power distribution automation terminal box. The guide rod 131 is rotatably connected inside the sliding groove 13. The sliding frame 3 is slidably connected to the side wall of the guide rod 131. The sliding frame 3 is slidably connected inside the sliding groove 13 via the guide rod 131. An installation cylinder 302 is installed inside one end of the sliding frame 3. A threaded hole 303 is provided on the inner wall of the installation cylinder 302. Two guide rods 131 are provided, each located on one side inside the main body 1 of the power distribution automation terminal box. One of the guide rods 131 has a side wall... The power distribution automation terminal box body 1 has a threaded groove and a first mounting cavity 11 inside. A first servo motor 12 is fixedly mounted on the inner wall of the first mounting cavity 11. A guide rod 131 with a threaded groove is fixedly mounted on the output end of the first servo motor 12. The threaded groove fits into the threaded hole 303. A sliding frame 3 is movably connected to the guide rod 131 through a mounting cylinder 302. A rack 301 is fixedly mounted inside the sliding frame 3. A rotating shaft 313 is rotatably connected inside the moving frame 31. A gear 314 is fixedly mounted on the side wall of the rotating shaft 313 and fits into the rack 301. A second threaded rod 315 is rotatably connected inside the moving frame 31. 5. Two movable frames are provided. The movable frame 32 is movably connected to the side wall of the second threaded rod 315. The transformer core 33 has a mounting shaft 333 fixedly installed inside. The two transformer cores 33 are rotatably connected to the movable frame 32 through the mounting shaft 333. One transformer core 33 has several teeth 334 fixedly installed on its side wall, and the other transformer core 33 has several grooves 335 that mesh with the teeth 334 on its side wall. The grooves 335 mesh with the teeth 334. When it is necessary to check the internal wiring of the distribution automation terminal box 1 during operation and maintenance, the movable door 101 is opened, and then the guide rod 131 is rotated through the guide rod 131 with threaded grooves. The sliding frame 31 engages with the threaded hole 303 inside the mounting cylinder 302, allowing the sliding frame 3 to slide up and down inside the power distribution automation terminal box body 1. Then, through the rotation of the gear component 314, it engages with the rack 301, allowing the movable frame 31 to slide on the side wall of the sliding frame 3. This allows the transformer core 33 on one side of the movable frame 31 to move laterally inside the power distribution automation terminal box body 1. The distance between the movable frame 32 and the movable frame 31 can be adjusted by rotating the second threaded rod 315, thereby adjusting the distance between the transformer core 33 and the wires inside the power distribution automation terminal box body 1. This allows the transformer core 33 to be clamped and detected more accurately inside the power distribution automation terminal box body 1.

[0049] In some embodiments, see Figure 7 , Figure 8The bottom of the movable frame 32 is fixedly installed with a fifth servo motor 321. One of the mounting shafts 333 is fixedly installed at the output end of the fifth servo motor 321. The fifth servo motor 321 can be used to control the rotation of the mounting shaft 333. The rotation of the mounting shaft 333 can be used to control the rotation of one of the current transformer cores 33. When one of the current transformer cores 33 rotates, the teeth 334 and the grooves 335 can drive the other current transformer core 33 to rotate in the opposite direction at the same time, thereby realizing the clamping or opening of the two current transformer cores 33.

[0050] In some embodiments, see Figure 2 , Figure 6 , Figure 7 A third servo motor 311 and a fourth servo motor 312 are fixedly installed on one side of the movable frame 31. A rotating shaft 313 is fixedly installed at the output end of the third servo motor 311. A second threaded rod 315 is fixedly installed at the output end of the fourth servo motor 312. By setting the fourth servo motor 312, the rotation of the second threaded rod 315 can be controlled, thereby adjusting the position of the movable frame 32 on one side of the movable frame 31. This allows the current transformer core 33 inside the movable frame 32 to better clamp and detect the wire. By setting the third servo motor 311, the rotation of the rotating shaft 313 can be controlled, thereby controlling the rotation of the gear component 314. By controlling the rotation of the gear component 314, the gear component 314 can mesh with the rack 301, adjusting the position of the movable frame 31 on the side wall of the sliding frame 3.

[0051] In some embodiments, see Figure 6 , Figure 9 An electric push rod 304 is fixedly installed inside one end of the sliding frame 3. A snap-fit ​​component 306 is fixedly installed at the output end of the electric push rod 304. The snap-fit ​​component 306 is slidably connected to the inside of one end of the sliding frame 3 via the electric push rod 304. Several snap-fit ​​grooves 305 are opened on the side wall of the mounting cylinder 302. The snap-fit ​​component 306 fits into the snap-fit ​​grooves 305. The electric push rod 304 can be used to control the movement of the snap-fit ​​component 306. The snap-fit ​​component 306 can be snapped into the snap-fit ​​grooves 305 by moving, thereby controlling the rotation of the mounting cylinder 302. When the mounting cylinder 302 cannot rotate, the guide rod 131 with threaded groove can rotate to drive the sliding frame 3 to move. When the mounting cylinder 302 can rotate, the sliding frame 3 can quickly move to the bottom of the guide rod 131 and quickly move to the bottom of the power distribution automation terminal box body 1, achieving the effect of quick reset.

[0052] In some embodiments, see Figure 2 , Figure 3The power distribution automation terminal box body 1 has a locking mechanism inside one side. The locking mechanism includes a first limiting block 1011, a limiting rod 104, a support spring 105, a second limiting block 106, and a lever 1062. The first limiting block 1011 is fixedly installed on one side of the movable door 101. One end of the movable door 101 has a movable groove 102 corresponding to the first limiting block 1011. A movable cavity 103 is opened on one side of the movable groove 102. The limiting rod 104 is fixedly installed on the other side. A second limiting block 106 is fixedly installed on the inner wall of the movable cavity 103. A limiting hole 1061, which matches the limiting rod 104, is opened inside the second limiting block 106. The second limiting block 106 is slidably connected to the side wall of the limiting rod 104 through the limiting hole 1061. A support spring 105 is fixedly installed between the inner wall of the movable cavity 103 and the second limiting block 106. A lever 1062 is fixedly installed on one side of the second limiting block 106. A through groove 107 is opened on one side of the movable cavity 103. Located inside the through groove 107, the first limiting block 1011 and the second limiting block 106 are both trapezoidal. By setting the first limiting block 1011 and the second limiting block 106, when the movable door 101 is opened, the first limiting block 1011 will first contact the second limiting block 106 inside the movable groove 102, pushing the second limiting block 106 into the movable cavity 103. Then, the second limiting block 106 will pop out under the support of the support spring 105, locking the first limiting block 1011 in the movable groove 102, preventing the movable door 101 from closing. This fixes the position of the movable door 101 after it is opened, preventing the movable door 101 from rotating randomly after it is opened, which would affect the operator's operation. By setting the lever 1062, the second limiting block 106 can be pulled to one side by moving the lever 1062, so that the first limiting block 1011 is disengaged from the limit of the second limiting block 106, allowing the movable door 101 to close.

[0053] In some embodiments, see Figure 11 , Figure 12The remote control mechanism includes a camera 19, an operation box 2, a control panel 202, a wireless connector 203, and a signal antenna 204. The operation box 2 is fixedly installed on the top of the power distribution automation terminal box 1. The camera 19 is installed inside the power distribution automation terminal box 1. The control host 201 is fixedly installed inside the operation box 2. The control host 201 contains a central processing unit 205. The signal antenna 204 is fixedly installed on the connection section of the wireless connector 203. The wireless connector 203 is fixedly installed on the control host 2. On one side, ammeter 331 is fixedly installed on the side wall of one of the current transformer cores 33, and a secondary winding 336 of the current transformer is fixedly installed on one side of the current transformer core 33. The other end of the secondary winding 336 is in contact with one side of the other current transformer core 33. A wireless connection module 332 is fixedly installed inside ammeter 331. During measurement, the wire is directly clamped by the current transformer core 33, so that the wire is located on one side of the secondary winding 336 inside the current transformer core 33. If the reading of ammeter 331 is zero, it indicates that... If there is no leakage in the circuit, and the reading of ammeter 331 is not zero, it indicates that there is leakage in the circuit. Wireless connection module 332 is connected to wireless connector 203. By setting wireless connection module 332, ammeter 331 can be connected to central processing unit 205 in control host 201 through wireless connector 203, so that the detected data can be transmitted to control host 201. By setting wireless connector 203, control host 201 can be wirelessly connected to the outside, so as to realize the effect of remote control and make operation and maintenance more convenient. Central processing unit 205 is connected to first servo motor 12, second servo motor 16, third servo motor 311, fourth servo motor 312, fifth servo motor 321 and electric push rod 304 for control. By setting camera 19, it can be used to capture the internal image of power distribution automation terminal box 1, so that the internal situation of power distribution automation terminal box 1 can be observed through control host 201 and camera 19. Control panel 202 is installed on one side of control host 201.

[0054] In some embodiments, see Figure 2 , Figure 5The power distribution automation terminal box body 1 has an adjustment groove 14 on its inner wall. A first threaded rod 17 is rotatably connected inside the adjustment groove 14. A slider 18 is movably connected to the side wall of the first threaded rod 17. The slider 18 is slidably connected inside the adjustment groove 14 through the first threaded rod 17. A camera 19 is fixedly installed at the bottom of the slider 18. The power distribution automation terminal box body 1 has a second mounting cavity 15 inside. A second servo motor 16 is fixedly installed inside the second mounting cavity 15. The first threaded rod 17 is fixedly installed at the output end of the second servo motor 16. By setting the second servo motor 16, the rotation of the first threaded rod 17 can be controlled. The rotation of the first threaded rod 17 can be used to control the movement of the slider 18 inside the adjustment groove 14, thereby controlling the position of the camera 19.

[0055] The workflow and principle of this invention are as follows: During the operation and maintenance of the power distribution automation terminal box 1, the operation box 2 is first opened, and the control host 201 is operated through the control panel 202. The camera 19 captures the internal image of the power distribution automation terminal box 1, and displays it through the control host 201. When it is necessary to detect a certain line inside the power distribution automation terminal box 1, the electric push rod 304 extends, causing the snap-fit ​​306 to snap into the snap-fit ​​groove 305. When the mounting cylinder 302 cannot rotate, the first servo motor 12 is controlled to run, which can drive the guide rod 131 with threaded grooves to rotate. The guide rod 131 with threaded grooves engages with the threaded hole 303 inside the mounting cylinder 302, so that the sliding frame 3 moves in the power distribution automation terminal box. The end box body 1 slides up and down inside. The rotation of the rotating shaft 313 can be controlled by the third servo motor 311, which in turn controls the rotation of the gear 314. By controlling the rotation of the gear 314, the gear 314 can mesh with the rack 301, adjusting the position of the moving frame 31 on the side wall of the sliding frame 3. The rotation of the second threaded rod 315 can be controlled by the fourth servo motor 312, thereby adjusting the position of the movable frame 32 on one side of the moving frame 31. This allows the current transformer core 33 inside the movable frame 32 to better clamp and detect the wire. By adjusting, the current transformer core 33 is moved to the side of the wire to be detected. The rotation of the mounting shaft 333 can be controlled by the fifth servo motor 321. The rotation of the mounting shaft 333 can control the rotation of one of the current transformer cores 33. When one current transformer core 33 rotates, it can drive the other current transformer core 33 to rotate in the opposite direction simultaneously through the teeth 334 and the slots 335, thereby clamping the two current transformer cores 33 and positioning the wire on one side of the secondary winding 336 inside the current transformer core 33. If the ammeter 331 reads zero, it indicates that there is no leakage in the circuit. If the ammeter 331 reads non-zero, it indicates that there is leakage in the circuit. The wireless connection module 332 is connected to the wireless connector 203. By setting the wireless connection module 332, the ammeter 331 can be connected to the central processing unit in the control host 201 through the wireless connector 203. The device 205 is connected to the control host 201, so that the detection data can be transmitted to the host, and the detection status can be directly observed. When the line has a problem and needs maintenance, the movable door 101 is opened. When the movable door 101 is opened, the first limit block 1011 will first contact the second limit block 106 inside the movable groove 102, pushing the second limit block 106 into the movable cavity 103. Then, the second limit block 106 is popped out under the support of the support spring 105, locking the first limit block 1011 in the movable groove 102, so that the movable door 101 cannot be closed, and the position of the movable door 101 after it is opened is fixed to prevent the movable door 101 from rotating randomly after it is opened, which would affect the operator's operation.

Take pictures of the internal screen of the power distribution automation terminal box (1) through the camera (19) and display them through the control host (201). When it is necessary to detect a certain line inside the power distribution automation terminal box (1), the electric push rod (304) extends to make the snap-fit ​​piece (306) snap into the snap-fit ​​groove (305). When the mounting cylinder (302) cannot rotate, control the first servo motor (12) to run and drive the guide rod (131) with threaded groove to rotate. Through the guide rod (131) with threaded groove and the mounting cylinder (302) The internal threaded hole (303) engages, allowing the sliding frame (3) to slide up and down inside the power distribution automation terminal box body (1).
