Description

Technical Field

[0001] The utility model provides a power grid fault locating device for a power grid GIS three-dimensional platform, belonging to the technical field of power grid fault locating. Background Art

[0002] The 3D Power Grid GIS platform is a power management hub that integrates geographic information systems and 3D modeling technologies. It builds a digital twin system using high-precision geographic data and 3D models of power grid equipment, enabling three-dimensional management of power grid spatial resources. In the field of power grid operation and maintenance, transmission line fault location is crucial for ensuring a stable power supply. The 3D Power Grid GIS platform analyzes information provided by multiple fault location devices to accurately pinpoint fault locations and ensure power supply.

[0003] However, with the continuous expansion of power grids and the increasing complexity of their structures, traditional fault location methods have many limitations. Existing fault location devices often require manual operation to wrap the cables with conductive rubber to achieve electrical connection and signal acquisition. This method is not only inefficient but also prone to problems such as uneven wrapping and unreliable connections, affecting the accuracy and timeliness of fault location. Furthermore, after wrapping the conductive rubber, the fault location device must be manually fixed to the cable by turning bolts. This process is cumbersome and requires workers to possess certain professional skills and experience. The difficulty of operation is further increased when working at height or in confined spaces. A slight mistake can cause the tool to fall, or even cause a safety accident such as a fall, posing a serious threat to the safety of workers. Furthermore, manual installation methods make it difficult to ensure the installation accuracy of the fault location device, which may affect the electrical connection performance between the device and the cable, reducing the reliability and efficiency of fault location.

[0004] Therefore, it is necessary to provide a new power grid fault location device for a power grid GIS three-dimensional platform to solve the above technical problems. Utility Model Content

[0029] like Figures 1 to 5 As shown, the utility model provides a power grid fault locating device for a power grid GIS three-dimensional platform, the device comprising: a base 1, a fixed shell 2 fixedly connected to the top of the base 1, fixed baffles 3 fixedly connected to both sides of the fixed shell 2, a fault locating device body 4 fixedly connected inside the fixed shell 2, a Y-shaped rod 5 symmetrically fixedly connected inside the fixed shell 2, a movable shell 6 installed on the fixed shell 2, a rotating rod 7 fixedly connected to the bottom of the movable shell 6, both ends of the rotating rod 7 are rotatably connected to the fixed shell 2, movable baffles 8 fixedly connected to both sides of the movable shell 6, slots are respectively provided on the movable baffle 8 and the fixed baffle 3 for installing a cable body 9, a winding roller 10 is further installed in the fixed shell 2, a conductive rubber 11 is installed on the outer wall of the winding roller 10, an opening and closing component for opening and closing the movable shell 6 is installed inside the fixed shell 2, a driving component for driving the winding roller 10 to rotate is installed inside the fixed shell 2, and a plane formed after the fixed baffle 3 and the movable baffle 8 are closed has an angle with the horizontal plane at the bottom of the base 1.

[0030] It should be noted that the fault location device body 4 sends information to the power grid GIS three-dimensional platform by regularly transmitting wireless signals, reducing battery power consumption. When the fault location device body 4 identifies a fault signal, it will continuously send information to the power grid GIS three-dimensional platform to issue an alarm, and the power grid GIS three-dimensional platform will find the fault location through data analysis. The rotation of the winding roller 10 can drive the conductive rubber 11 to wrap around the cable body 9. The conductive rubber 11 has good conductivity and can form a reliable electrical connection with the outer surface of the cable body 9. This enables the fault location device body 4 to accurately detect electrical signals such as current and voltage in the cable body 9, providing accurate data for fault location. The conductive rubber 11 can also prevent external electromagnetic waves from interfering with the internal signals of the cable body 9, and also prevent the signals in the cable body 9 from generating electromagnetic radiation to the outside world, ensuring that the signals obtained by the fault location device body 4 are accurate and reliable, reducing the possibility of errors and misjudgments. The angle design allows the device to be vertically raised close to the cable body 9 to place the cable body 9 in the slots of the two fixed baffles 3, achieving the effect of quickly aligning the cable body 9 and improving installation efficiency.

[0031] See also Figures 2 to 3 The opening and closing assembly includes: a drive motor 21, a first gear 22 and a second gear 23. The drive motor 21 is fixedly installed in the fixed shell 2, the output end of the drive motor 21 is fixedly connected to the first gear 22, the middle part of the rotating rod 7 is fixedly connected to the second gear 23, the first gear 22 and the second gear 23 are engaged, and a battery is fixedly connected to the inside of the fault locating device body 4, and the drive motor 21 is electrically connected to the battery.

[0032] It should be noted that: since the first gear 22 is engaged with the second gear 23 in the middle of the rotating rod 7, the second gear 23 is driven to rotate, and then the rotating rod 7 is rotated. The rotating rod 7 drives the movable shell 6 to rotate around the fixed shell 2, and the movable baffles 8 on both sides of the movable shell 6 rotate accordingly to realize the opening and closing of the movable shell 6. The movable baffle 8 and the fixed baffle 3 jointly clamp the cable body 9 to complete the fixation of this device.

[0033] See also Figures 2 to 5 The driving assembly includes: a transmission rod 31, a third gear 32, an active roller 33, a driven roller 34, an auxiliary roller 35 and a U-shaped rod 36. The transmission rod 31 is rotatably connected between the two Y-shaped rods 5. The middle part of the transmission rod 31 is fixedly connected to the third gear 32, and the third gear 32 is engaged with the first gear 22. The side of the Y-shaped rod 5 close to the transmission rod 31 is rotatably connected to the active roller 33, and the side of the Y-shaped rod 5 close to the transmission rod 31 is symmetrically rotatably connected to the driven roller 34. The side of the Y-shaped rod 5 close to the transmission rod 31 is equidistantly rotatably connected to the auxiliary roller 35. Both ends of the transmission rod 31 are fixedly connected to the corresponding active roller 33. The active roller 33 and the corresponding driven roller 34 are driven by a belt. The U-shaped rod 36 is placed inside the multiple groups of auxiliary rollers 35 and the driven roller 34.

[0034] Among them, the diameter of the second gear 23 is twice the diameter of the first gear 22, the diameter of the first gear 22 is twice the diameter of the third gear 32, the U-shaped rod 36 opens upward, the winding roller 10 is fixedly connected to the two U-shaped rods 36, and the multiple auxiliary rollers 35 are located on both sides of the U-shaped rod 36.

[0035] It should be noted that the auxiliary roller 35 assists the U-shaped rod 36 in rotating, ensuring the stable operation of the U-shaped rod 36 .

[0036] The working principle of the power grid fault location device for the power grid GIS three-dimensional platform provided by the utility model is as follows:

[0037] Opening and closing components work:

[0038] When the device needs to be installed on the cable body 9, the device is vertically raised close to the cable body 9 in the open state, and the cable body 9 is placed in the slots of the two fixed baffles 3, and the cable body 9 is simultaneously located in the U-mouths of the two U-shaped rods 36. At this time, one end of the conductive rubber 11 on the winding roller 10 is bonded to the cable body 9, and the drive motor 21 is started. The first gear 22 at the output end of the drive motor 21 rotates. Since the first gear 22 is engaged with the second gear 23 in the middle of the rotating rod 7, the second gear 23 is driven to rotate, and then the rotating rod 7 is rotated. The rotating rod 7 drives the movable shell 6 to rotate around the fixed shell 2, and the movable baffles 8 on both sides of the movable shell 6 rotate accordingly, realizing the opening and closing of the movable shell 6. The movable baffle 8 and the fixed baffle 3 jointly clamp the cable body 9 to complete the fixation of the device;

[0039] Drive component work:

[0040] When the driving motor 21 drives the first gear 22 to rotate, since the third gear 32 is meshed with the first gear 22 and the third gear 32 is fixed to the middle of the transmission rod 31, the transmission rod 31 rotates, and both ends of the transmission rod 31 are fixedly connected to the active roller 33, thereby driving the active roller 33 to rotate, and the active roller 33 drives the driven roller 34 to rotate through a belt transmission. A U-shaped rod 36 is placed on one side of the auxiliary roller 35 and the driven roller 34. The winding roller 10 is fixedly connected to the two U-shaped rods 36. The rotating belt drives the U-shaped rod 36 and the winding roller 10 to rotate with the axis of the cable body 9 as the rotation center through friction, so that the conductive rubber 11 on the outer wall of the winding roller 10 is evenly wound around the cable body 9. Through this transmission method, the conductive rubber 11 automatically wraps the cable body 9. When the movable shell 6 is completely closed, the conductive rubber 11 completes the winding of the cable body 9.

[0041] Overall operation:

[0042] After the device is installed, the fault location device body 4 starts working, and is electrically connected to the cable body 9 through the conductive rubber 11. The fault location device body 4 is based on the traveling wave principle. When a fault occurs in the cable body 9 and a traveling wave is generated, the sensor in the fault location device body 4 senses the traveling wave and accurately measures the time and waveform characteristics of the traveling wave reaching each sensor. These signals are transmitted to the device for processing and interact with the power grid GIS three-dimensional platform for data. The power grid GIS three-dimensional platform accurately locates and visualizes the fault location based on the spatial information of the cable and the collected electrical signals. During the entire operation process, the battery powers the drive motor 21 to ensure the normal operation of the device.
