Among them, the fault indicator can be installed in the middle section of the long line and at the entrance of the branch to indicate the line fault area and the fault branch; it can also be installed at the exit of the substation to determine whether it is an internal or external fault; it can also be installed at the user's distribution transformer high-voltage incoming line to determine whether the fault is caused by the user; it can also be installed at the connection between the cable and the overhead line to distinguish whether the fault is in the cable section.

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Please also read Figures 1 to 7, the 10KV line grounding fault detection device provided by the present invention is now described. The 10KV line grounding fault detection device comprises a lift 1, a mechanical arm 2, a plurality of fault indicators 3 and a grounding fault detection system 4, the lift 1 has a telescopic freedom in the height direction, a moving part 11 is connected to the bottom of the lift 1, the moving part 11 has a freedom to move in any direction, a rotating platform 5 is connected to the top of the lift 1, and the upper end of the rotating platform 5 has a circumferential rotation freedom in the horizontal plane; the mechanical arm 2 is connected to the upper end of the rotating platform 5, and has a clamping end 21 that can move in multiple directions and is suitable for clamping, and the rotating platform 5 is suitable for controlling the rotation of the mechanical arm 2 to adjust the clamping position of the clamping end 21; multiple fault indicators 3 are all placed on the top of the lift 1, and the mechanical arm 2 is suitable for controlling the movement of the clamping end 21 and clamping multiple fault indicators 3 in sequence, and then respectively installed on the line or the substation outlet; the grounding fault detection system 4 is respectively connected to the multiple fault indicators 3 in communication, and the grounding fault detection system 4 is suitable for respectively detecting the operating status of the multiple fault indicators 3 to judge the fault line.

[0042] Compared with the prior art, the 10KV line grounding fault detection device provided by the present invention can be raised and lowered by setting a lift 1, and multiple fault indicators 3 can be installed in sequence on multiple lines or substation outlets by setting a mechanical arm 2. The clamping position of the mechanical arm 2 can be adjusted by a rotating table 5. The line grounding fault can be received and detected in real time by using a grounding fault detection system 4, and the detection result can be output if a fault occurs. The technical problem that the fault indicator 3 is not convenient to install on the line or at the substation outlet, and there are safety hazards during installation, making it inconvenient to perform grounding fault detection, is solved. The device has the technical effect of being able to automatically install the fault indicator 3, eliminating manual climbing operations, reducing safety hazards, and facilitating grounding fault detection.

[0043] The fault indicator 3 used in this embodiment is a prior art product, which can detect the grounding fault of the line and send a signal if there is a fault. The grounding fault detection system 4 is a system that can automatically detect and analyze the operating status of multiple fault indicators 3 to judge the fault line. The grounding fault detection system 4 is a prior art, such as a comprehensive test system for the performance of single-phase grounding fault judgment of a power distribution terminal. The specific detection and analysis principles can refer to the prior art. In this embodiment, the lifting height of the elevator 1 can realize the installation of the fault indicator 3. During the installation process, the mechanical arm 2 does not contact the line and can realize the live installation. The clamping end 21 of the mechanical arm 2 can realize the clamping of the fault indicator 3 and install the fault indicator 3 on the line. The fault indicator 3 is a prior art product, which can be easily installed on the line and will not be separated from the line after installation. Generally, if there are three lines, three fault indicators 3 need to be installed in sequence. If the installation position needs to be adjusted, it can be moved by moving the elevator 1. The moving part 11 includes a motor and a plurality of wheels. The motor can drive two wheels to rotate, thereby moving the moving part 11. The position of the moving part 11 after moving can be locked, that is, the motor is stopped and the wheels are locked. The rotating table 5 is an electric rotating table, which can be controlled to rotate, such as clockwise or counterclockwise, and then the clamping direction of the mechanical arm 2 can be adjusted, and then the fault indicator 3 at different positions can be installed on the line. By setting the mechanical arm 2 and the rotating table 5, the installation of the fault indicator 3 is facilitated. The mechanical arm 2 is a six-axis freedom manipulator in the prior art, which can realize position adjustment or movement in multiple directions, thereby facilitating the installation of the fault indicator 3.

[0044] In order to accommodate or place multiple fault indicators 3 and facilitate installation on the line, in some embodiments, refer to Figure 1, a rotating plate 6 is hinged on one side of the top of the lift 1. The rotating plate 6 has the freedom to rotate toward or away from the mechanical arm 2. The rotating plate 6 has multiple accommodating chambers 61. Multiple fault indicators 3 are respectively placed in the multiple accommodating chambers 61. The clamping end 21 clamps and takes out the fault indicators 3 from the multiple accommodating chambers 61 in turn. The rotating plate 6 is equivalent to a container for placing multiple fault indicators 3. It can move with the lifting of the lift 1, so as to facilitate the mechanical arm 2 to take out the fault indicators 3. As a preference, three accommodating chambers 61 are usually provided on the rotating plate 6. Since it is installed on three lines, the mechanical arm 2 takes out the fault indicators 3 from the three accommodating chambers 61 in turn, and then can be installed on the line or the substation outlet. After the installation is completed, it is convenient to perform ground fault detection. The position of the rotating plate 6 relative to the top of the lift 1 can be locked, that is, the position after rotation can be locked, and the use of the rotating plate 6 cannot affect the placement of the fault indicator 3. The depth of the accommodating cavity 61 is approximately half of the thickness of the fault indicator 3 . The fault indicator 3 can be snapped into the accommodating cavity 61 and prevented from falling naturally. If clamped by a robotic arm 2 , it can be taken out of the accommodating cavity 61 .

[0045] When installing the fault indicator 3, in order to realize automatic operation, in some embodiments, refer to Figure 1 The mechanical arm 2 is electrically connected to a wireless communication unit. The 10KV line grounding fault detection device also includes a remote controller 7 that is wirelessly connected to the wireless communication unit. The remote controller 7 is suitable for controlling the operation of the mechanical arm 2. The remote controller 7 is also connected to the grounding fault detection system 4 and is suitable for receiving the fault line information output by the grounding fault detection system 4. The remote controller 7 has a control module that can control the operation of the mechanical arm 2 and the operation of the elevator 1. By manipulating the remote controller 7, the operation of the mechanical arm 2 and the elevator 1 can be controlled, and then the automatic lifting and adjusting of the fault indicator 3 during installation and the automatic grabbing and installation of the fault indicator 3 can be realized. After installation, grounding fault detection can be performed. The grounding fault detection system 4 can output detection information after detection, and will synchronously send the detection result to the remote controller 7, and the detection result can be displayed on the display screen on the remote controller 7.

[0046] In some embodiments, see Figures 4 to 5The fault indicator 3 includes a fault indicator body 31, a frame 32, a wireless communication module 33, a positioning module 34 and a monitoring module 35. The fault indicator body 31 is a product in the prior art and can detect the grounding fault of the line. The fault indicator body 31 is slidably connected to the inside of the frame 32, and the frame 32 can be limited relative to the fault indicator body 31. The wireless communication module 33 is connected to the inner wall of the frame 32 and is suitable for sending and receiving wireless communication signals. The positioning module 34 is connected to the inner wall of the frame 32 and is suitable for locating the current position of the fault indicator body 31. The monitoring module 35 is connected to the top of the frame 32 and is suitable for video monitoring of the lines or substation exits around the fault indicator body 31. The positioning module 34 and the monitoring module 35 are both wirelessly connected to the remote controller 7 through the wireless communication module 33. The remote controller 7 is suitable for receiving the current position information of the fault indicator body 31 and the information monitored by the monitoring module 35. The purpose of the frame 32 is to facilitate the installation of the wireless communication module 33, the positioning module 34 and the monitoring module 35. The setting of the frame 32 does not affect the normal use of the fault indicator 3. The frame 32 is in the shape of a gate, and the connection end between the fault indicator 3 and the line is located at the lower end of the fault indicator 3. The frame 32 does not affect the clamping and operation of the mechanical arm 2, nor does it affect the installation of the mechanical arm 2 on the line after clamping the fault indicator 3. The wireless communication module 33 can realize wireless communication with the outside world, and can transmit positioning information and monitoring information to the remote control 7. The frame 32 is made of insulating material, and the wireless communication module 33 and the positioning module 34 are both at a certain distance from the line, that is, they do not affect each other. The wireless communication module 33 and the positioning module 34 are both electronic products of the prior art, which can realize wireless communication with the outside world and locate the fault indicator 3.

[0047] The staff can see the information detected by the fault indicator body 31 by holding the remote control 7. The monitoring module 35 can monitor the information of the outer surface of the surrounding lines, such as stains, cracks, breaks, etc. If the outer wall of some lines has quality defects, it can be seen through the monitoring module 35, which can remind the staff to pay attention to the quality of the line. The positioning module 34 can locate the current position of the fault indicator 3, so that the maintenance position can be accurately determined when the line is repaired later.

[0048] To achieve power supply, in some embodiments, refer to Figures 4 to 5 The frame 32 has a detachable power supply module 36 inside, which is electrically connected to the fault indicator body 31, the positioning module 34 and the monitoring module 35 and is used to supply power respectively. The power supply module 36 is a battery that can be removed from the frame 32 and can be powered by electrical connection. When the battery needs to be charged, it can be removed from the frame 32, which is convenient to use.

[0049] In some embodiments, see Figures 4 to 5 The frame 32 includes two side panels 321, a top panel 322 and two groups of slide rails 323. The two side panels 321 are arranged vertically and at intervals; the top panel 322 is arranged horizontally and connected to the tops of the two side panels 321. The wireless communication module 33 and the positioning module 34 are connected to the bottom wall of the top panel 322, and the monitoring module 35 is connected to the top of the top panel 322; the two groups of slide rails 323 are respectively connected to the inner walls of the two side panels 321, the slide rails 323 are arranged horizontally, and the two ends of the slide rails 323 extend to the ends of the side panels 321 respectively. Slide blocks 37 are arranged on the two opposite outer side walls of the fault indicator body 31. The two groups of slide blocks 37 are slidably connected to the two groups of slide rails 323 at the same time. A plurality of through holes 324 are arranged on the two side panels 321. A limiting member is penetrated in the through hole 324. The limiting member is used to pass through the through hole 324 and abut the slide block 37 to limit the position of the fault indicator body 31 on the slide rail 323. The two side panels 321 are respectively located on the left and right sides of the fault indicator body 31. The setting of the frame 32 does not affect the normal use of the fault indicator body 31. The top plate 322 is located above the fault indicator body 31 and does not contact each other. In order to enable the fault indicator body 31 to slide inside the frame 32, two sets of slide rails 323 are provided for the fault indicator body 31 to slide. In order to prevent the fault indicator body 31 from slipping off the slide rails 323, limit blocks (not shown in the figure) are provided at both ends of the slide rails 323. When it is necessary to limit the position of the fault indicator body 31 in the frame 32, a limiter can be used to pass through a through hole 324 at a corresponding position, and the limiter can play a role in limiting the slider 37. A plurality of through holes 324 are provided and are arranged in sequence along the sliding direction of the fault indicator body 31.

[0050] Preferably, a photovoltaic power supply component 325 is provided on the outer wall of the frame 32, and the power output end of the photovoltaic power supply component 325 is electrically connected to the battery and can charge the battery, so that the battery can be charged during field operations to avoid affecting the technical effect of use.

[0051] In addition to line ground fault detection, in some embodiments, see Figure 5The side wall of the side plate 321 is connected with a vertical rail 326, which is arranged in a vertical shape. A machine vision detection component 327 is slidably connected to the vertical rail 326. The machine vision detection component 327 is suitable for machine vision detection of the line or substation outlet around the fault indicator body 31, and can output the detection result after detection. The detection height of the machine vision detection component 327 can be adjusted and limited. The machine vision detection component 327 is connected with the remote control 7 by wireless communication and its operation is controlled by the remote control 7. The machine vision detection component 327 can realize machine vision detection of the line or substation outlet. The purpose of the detection is to perform machine vision detection on the quality defects of the line appearance. For example, if the line appearance has cracks, stains, impurities, etc., it can be detected by the machine vision detection component 327, and the detection result can be output, which can remind the staff to pay attention so that the section of the line can be repaired or cleaned later to avoid affecting the normal use of the line. The height of the machine vision detection component 327 can be adjusted by sliding on the vertical rail 326. After adjustment, it is limited on the vertical rail 326. The detection result of the machine vision detection component 327 can be received and seen through the remote control 7. The machine vision detection component 327 includes an industrial CCD camera, etc., which can shoot or collect images toward the line. Through the built-in database, it can be analyzed and judged whether there are appearance quality defects in this section of the line. For the specific operating principle of the machine vision detection component 327, reference can be made to the prior art.

[0052] In some embodiments, see Figure 6 to Figure 7 , a slideway 328 is provided on the top of the frame 32, and the monitoring module 35 has the freedom to slide in the slideway 328. The slideway 328 is provided to facilitate the movement or adjustment of the position of the monitoring module 35, so that the monitoring module 35 can monitor or collect image information for lines at different positions or in different directions. The slideway 328 in this embodiment can be in a cross shape, a T-shape, a straight shape, or the like.

[0053] To automatically adjust the position of the monitoring module 35, in some embodiments, refer to Figure 6 to Figure 7A push rod 38 and a slide groove 39 are provided at the top of the frame 32. The length direction of the slide groove 39 is parallel to the length direction of the slideway 328. A limit block 310 is slidably connected in the slide groove 39. The limit block 310 is connected to the monitoring module 35 through a connecting rod 311. One end of the push rod 38 is connected to the top of the frame 32 and the other end is connected to the limit block 310. The push rod 38 is suitable for pushing the limit block 310 to slide, and then pushing the monitoring module 35 to slide in the slideway 328, so that the monitoring module 35 can monitor the lines or substation outlets at different positions. The push rod 38 is wirelessly connected to the remote control 7 and its operation is controlled by the remote control 7. By controlling the extension and retraction of the push rod 38 on the remote controller 7, the limit block 310 can slide in the slide groove 39, and the linkage of the connecting rod 311 can push the monitoring module 35 to slide, thereby adjusting the position of the monitoring module 35. The connecting rod 311 has various shapes. Different sizes can be reasonably selected according to different working conditions or the pushing distance of the monitoring module 35. Straight rods or curved rods can be selected. The purpose is to achieve the connection with the limit block 310 and the monitoring module 35, and the monitoring module 35 can be pushed to move through the connection. In this embodiment, the sliding of the monitoring module 35 is parallel to the pushing direction of the push rod 38, and cannot slide in other directions.

After the rotating disk 351 rotates, the monitoring direction of the monitor 352 can be adjusted, so that the lines or substations in different directions can be monitored. After monitoring, the staff can receive the monitoring picture or information through the remote controller 7, so as to monitor the surrounding conditions of the lines or substations. The rotating disk 351 is an electric rotating table 5 in the prior art. The monitoring information can be viewed by operating the remote controller 7.
