Description

Technical Field

[0001] The present invention belongs to the technical field of power grid equipment warning, and specifically relates to a power grid equipment fault warning device and its usage method. Background Art

[0002] As an important part of urban power supply, the stable operation of the distribution network is crucial for people's life and work. However, due to various reasons, such as equipment aging, external force damage, etc., short circuits and grounding faults often occur in the distribution network, posing safety hazards and losses to power supply. In order to detect faults in a timely manner and accurately locate them, a traveling wave type fault warning and positioning device for the distribution network has emerged.

[0003] The traveling wave type fault warning and positioning device for the distribution network is installed on the line. Through sensors and monitoring devices installed on the wires, it can collect data such as voltage, current, and resistance of the wires in real time, and transmit the data to the data processing center through wireless communication. By using big data analysis and intelligent algorithms to monitor and analyze the collected data, it can identify fault signals such as wire short circuits and groundings, and send warning signals to remind maintenance personnel to carry out repairs, making great contributions to the stable operation of the distribution network. During the long-term use of the traveling wave type fault warning and positioning device for the distribution network, it usually needs to be maintained. In daily maintenance, not only does it need to be inspected to observe its appearance, but also it needs to be cleaned, calibrated, and updated regularly to maintain the accuracy and sensitivity of the traveling wave type fault warning and positioning device for the distribution network in identifying wire faults. However, since the traveling wave type fault warning and positioning device for the distribution network is installed on the overhead line and is fixedly connected to the wire through a fixed structure to ensure the stable connection between the device and the line, during maintenance or repair, the staff needs to disassemble and reinstall it. Due to the large fixing strength between the device and the wire, during the frequent disassembly and installation process, not only is the operation difficult, but also it is easy to damage the wire insulation layer.

[0004] The related technology discloses a traveling wave fault warning and positioning device for the distribution network, with the application number CN2023111749751. In this solution, by setting a buffer clamping component, when the locking ring moves, the annular clamping piece will generate a large clamping force on the cable. To prevent damage to the cable during clamping, through the sliding cooperation of the inner cavity of the mounting post, the elastic member, and the positioning post, the annular clamping piece has a buffering effect from the elastic member during clamping, reducing damage to the outer peripheral wall of the cable and improving the service life of the cable outer shell. However, it is found in the actual application process that although the elastic clamping can effectively reduce the damage of the device to the wire, the complex structure makes the frequent installation and disassembly of the device on the wire more troublesome, so that the maintenance and repair operations of the device by the staff are more cumbersome.

Specific embodiments

[0045] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0046] As Figures 1 to 10 shown, a power grid equipment fault warning device of the present invention includes a fault warning main body, the fault warning main body is composed of a left end 1 and a right end 11, a detection groove 12 is jointly opened on the left end 1 and the right end 11, and the fault warning main body is sleeved on the cable through the detection groove 12;

[0047] It further includes a combined fixing component, the combined fixing component is installed on the cable, and the combined fixing component is used to fix the fault warning main body;

[0048] The combined fixing component includes a fixed frame plate 2, a positioning hoop 21 and a connecting pipe 25;

[0049] The fixed frame plate 2 is a frame-shaped plate-like structure body, the two fixed frame plates 2 are fixedly connected by connecting bolts, connection grooves 22 are opened on both the left end 1 and the right end 11, and the left end 1 and the right end 11 are connected to the fixed frame plate 2 through the connection grooves 22;

[0050] A positioning hoop 21 is installed in the middle of the fixed frame plate 2, and the fixed frame plate 2 is fixedly connected to the cable through the positioning hoop 21;

[0051] The bottom ends of the left end portion 1 and the right end portion 11 are hinged through a torsion spring. Step holes 23 are formed at the top ends of the left end portion 1 and the right end portion 11. A fixing bolt 24 is rotatably installed in the step holes 23. A connecting pipe 25 is installed on the fixed frame plate 2. The connecting pipe 25 is aligned with the step holes 23, and the connecting pipe 25 is threadedly connected to the fixing bolt 24.

[0052] During the normal use of the traveling wave fault warning device, in order to maintain the use effect of the traveling wave fault detection device, it is not only necessary to regularly clean, calibrate, and update the software of the device, but also when the device has a fault, it is necessary to repair and maintain the device in a timely manner. Since the traveling wave fault detection device is installed on the cable, in order to reduce the damage to the cable during frequent disassembly and assembly, a combined fixing component is provided in the present invention. The traveling wave fault detection device is installed on the cable through the combined fixing component. When disassembling and assembling the fault warning main body, there is no need to operate on the cable, thereby reducing the influence of device maintenance and repair on the cable.

[0053] Specifically, the combined fixing component includes a fixing frame plate 2, a positioning hoop 21 and a connecting pipe 25. The fixing frame plate 2 is symmetrically installed on both sides of the cable, and the two fixing frame plates 2 are fixed by connecting bolts. The positioning hoop 21 installed in the middle of the fixing frame plate 2 is used to fix the position between the fixing frame plate 2 and the cable, so that the cable is always in the middle of the fixing frame plate 2, thereby providing an installation basis for the fault warning main body. The fault warning main body consists of a left end 1 and a right end 11. An induction power generation module for inductive power generation, a sensor module for detecting traveling waves, a wireless communication module for communication, etc. are installed in the left end 1 and the right end 11. By closing the left end 1 and the right end 11 and making the cable pass through the detection groove 12 commonly opened on the left end 1 and the right end 11, the cable can be subjected to traveling wave fault warning and positioning operations (this is a mature technology at present and will not be described in detail here). When assembling the fault warning main body and the combined fixing assembly, since the fixing frame plate 2 is a frame-shaped plate structure, connecting grooves 22 are opened on the left end 1 and the right end 11. The connecting grooves 22 are located on the side where the left end 1 and the right end 11 are close to each other. When the left end 1 and the right end 11 are closed, the connecting grooves 22 are aligned to form a chamber for combining with the fixing frame plate 2. The parts of the left end 1 and the right end 11 except the connecting grooves 22 correspond to the blank positions of the fixing frame plate 2. When the left end 1 and the right end 11 are closed, this part is used to connect with the cable. Since the bottoms of the left end 1 and the right end 11 are hinged, after the left end 1 and the right end 11 are clamped on the fixing frame, by turning the fixing bolt 24 in the stepped hole 23 with a tool, so that the fixing bolt 24 is threadedly connected with the connecting pipe 25, the fault warning main body can be fixed on the fixing frame plate 2. When maintaining or repairing the traveling wave fault warning device, the staff can turn the fixing bolt 24 to separate the fixing bolt 24 from the connecting pipe 25, and then the fault warning main body can be separated from the fixing frame plate 2. Since the main operation modules of the traveling wave fault warning device are all located on the fault warning main body, there is no need to disassemble the fixing frame plate 2. After the inspection or maintenance is completed, the fault warning main body and the fixing frame plate 2 are connected again and the fixing bolt 24 is reset.

[0054] In the present invention, by setting the combined fixing component, by fixedly installing the combined fixing component on the cable to form a fixed installation structure body, and then installing the fault warning main body on the combined fixing component. During the maintenance or repair process, only the connection between the fault warning main body and the combined fixing component needs to be disassembled and assembled, and the cable is not directly involved in the operation process. Therefore, during frequent disassembly and assembly, the surface layer of the cable will not be damaged. Since the connection method between the combined fixing component and the fault warning main body is relatively simple, the disassembly and assembly process of the fault warning main body is more convenient.

[0055] As a preferred embodiment of the present invention, sliding grooves 26 and fixing grooves 3 are formed in the fixing frame plates 2. The sliding grooves 26 extend to the middle of the fixing grooves 3. One end of the fixing groove 3 is open. The connecting pipes 25 are slidably installed in the sliding grooves 26. Fixing ropes 31 are fixedly installed on the connecting pipes 25. A pressing plate 32 is elastically installed in the fixing groove 3 through a spring. A combined groove 33 is formed in the pressing plate 32. The fixing ropes 31 extend into the combined groove 33. A clamping pipe 34 is fixedly installed at one end of the fixing rope 31 in the combined groove 33. In the initial state, the combined groove 33 is misaligned with the sliding groove 26.

[0056] During long-term use, when using bolts for connection, problems such as bolt corrosion may cause problems such as bolt slipping. Therefore, in the present invention, by providing the clamping pipe 34 and the fixing rope 31, there is another disassembly method for the fault warning main body and the fixing frame plate 2. Specifically, when the two fixing frame plates 2 are installed on the cable, the pressing plate 32 connected by the spring is installed in the fixing groove 3 formed by the left end portion 1 and the right end portion 11. A tool is used to press the pressing plate 32 so that the pressing plate 32 does not block the opening of the sliding groove 26. Then, the fixing rope 31 on the connecting pipe 25 is inserted into the sliding groove 26 and extends from the sliding groove 26 into the fixing groove 3. Then, the pressing on the pressing plate 32 is released. The pressing plate 32 moves downward under the action of the spring and gradually aligns with the sliding groove 26. During this process, the clamping pipe 34 installed at the end of the fixing rope 31 gradually enters the combined groove 33 on the pressing plate 32. When the pressing plate 32 stops moving, at this time, the combined groove 33 is misaligned with the sliding groove 26, and the gap width between the two is smaller than the width of the clamping pipe 34. Therefore, the pressing plate 32 fixes the clamping pipe 34. When disassembling the fault warning main body and the fixing bolt 24 cannot be normally disassembled, the staff lifts the pressing plate 32 with a tool, so that the combined groove 33 on the pressing plate 32 is aligned with the sliding groove 26 again. At this time, the gap between the two increases, and the clamping pipe 34 can enter the sliding groove 26. By pulling the connecting pipe 25 by the fixing bolts 24 on the left end portion 1 and the right end portion 11, the long strip-shaped structure formed by the connecting pipe 25, the fixing rope 31, and the clamping pipe 34 can be separated from the sliding groove 26, thereby completing the disassembly of the fault warning main body.

[0057] As a preferred embodiment of the present invention, it further includes a remote operation component. The remote operation component includes an operating rod 4, an extension wire 41, and a clamping rod 42;

[0058] The connecting groove 22 is open at the bottom of the left end portion 1 and the right end portion 11. The operating rod 4 extends into the fixing groove 3 through the bottom opening of the connecting groove 22. The operating rod 4 is a hollow tubular structure. A rotating plate 43 is rotatably installed at the end of the operating rod 4. A through hole 44 is formed in the rotating plate 43. The diameter of the through hole 44 is smaller than the diameter of the clamping rod 42;

[0059] An extension line 41 is fixedly installed at the bottom of the clamping rod 42. The extension line 41 extends into the operating rod 4 through a through hole 44. The clamping rod 42 is in interference fit with the clamping tube 34. The clamping rod 42 and the clamping tube 34 are used to fixedly connect the extension line 41 and the fixing rope 31.

[0060] Since the traveling wave fault warning device is mostly installed on overhead electric wires, when the staff disassembles and installs the traveling wave fault warning device, they usually need to climb into the air with the help of tools. It is inconvenient for the staff in the air to operate, which leads to a relatively high probability of the staff accidentally touching the electric wire. Although the staff will wear protective equipment during the operation and cut off the power of the cable in the working section when necessary, when the staff works around the cable, due to the inconvenient operation, there will still be certain potential safety hazards to the cable or the staff. Therefore, a remote operation component is provided in the present invention. Through the remote operation component, the staff can operate in the air at a certain distance from the cable, so that the staff is separated from the cable and the degree of mutual influence between the staff and the cable is reduced.

[0061] Specifically, during actual operation, the staff climbs to the lower part of the cable installed with the fault warning device with the help of tools. Then, they hold the operating rod 4 and pull the extension line 41 inside the operating rod 4, causing the extension line 41 to be tightened, so that the clamping rod 42 is fixed on the rotating plate 43 at the end of the operating rod 4. Then, the staff holds up the operating rod 4 and inserts the operating rod 4 into the fixing groove 3 through the connecting groove 22 at the bottom of the fault warning main body. During the insertion process, by rotating the operating rod 4, the two clamping rods 42 are aligned with the combined groove 33. During the continuous upward movement of the operating rod 4, the clamping rod 42 gradually inserts into the clamping tube 34, so that the fixing rope 31 is connected to the extension line 41. Since the clamping rod 42 and the clamping tube 34 are in interference fit, a relatively large force is required to separate them after the clamping rod 42 and the clamping tube 34 are connected. Continuing to push the operating rod 4, the operating rod 4 gradually pushes the pressure plate 32, so that the combined groove 33 is aligned with the sliding groove 26. At this time, under the action of the gravity of the fault warning main body and the torsion spring between the left end 1 and the right end 11, the fault warning main body automatically opens and disengages from the fixed frame plate 2. As the fault warning main body continues to descend, the extension line 41 in the operating rod 4 gradually rises. When the descending degree of the fault warning main body reaches the requirement, the staff releases the lifting of the operating rod 4, causing the pressure plate 32 to reset. After the pressure plate 32 resets, it clamps the extension line 41 by the dislocation of the combined groove 33 and the sliding groove 26, so that the fault warning main body is suspended in mid-air. Thus, when the staff repairs or maintains the fault warning main body, it can avoid the influence of the cable. After the repair is completed, the staff holds up the operating rod 4 with one hand, pushes the combined groove 33 to align with the sliding groove 26, and pulls the extension line 41 with the other hand, so that the fault warning main body rises and resets. Finally, through the reset of the pressure plate 32, the clamping tube 34 is fixed again, and then by pulling the extension line 41 forcefully, the separation of the clamping tube 34 and the clamping rod 42 can be completed.

[0062] By setting the remote operation component, the present invention uses the remote operation component to enable the staff to complete the disassembly and assembly of the fault warning main body and the fixed frame plate 2 at a certain distance from the cable and repair the fault warning main body at a position far from the cable. Therefore, during the whole operation process, the mutual influence between the staff and the cable is effectively reduced, which can not only reduce the potential safety hazards during the repair process, but also enhance the convenience of the repair operation.

[0063] As a preferred embodiment of the present invention, a through slot 45 is opened on the clamping tube 34, a telescopic slot 46 is opened on the clamping rod 42, a clamping block 47 is elastically installed in the telescopic slot 46 through a spring, the clamping block 47 extends outside the telescopic slot 46, the clamping block 47 cooperates with the through slot 45, the size of the combined groove 33 matches that of the clamping tube 34, and the bottom of the sliding groove 26 is designed as an inclined surface for guiding the clamping tube 34 into the combined groove 33.

[0064] Using the method of forcefully inserting and pulling to achieve the disassembly and assembly of the clamping tube 34 and the clamping rod 42 will cause damage to the clamping tube 34 and the clamping rod 42, resulting in deformation problems, and further reducing the connection effect between the two. In order to maintain the connection effect between the two, by setting the telescopic groove 46 and the clamping block 47, when the clamping rod 42 is inserted into the clamping tube 34, the clamping block 47 on the clamping rod 42 contacts the clamping tube 34 through the inclined surface. Under the restriction of the clamping tube 34, the clamping block 47 is caused to contract into the telescopic groove 46. When the clamping rod 42 is aligned with the clamping tube 34, at this time the clamping block 47 is aligned with the through slot 45. When the staff continues to push the pressing plate 32 upward, the combined groove 33 is gradually aligned with the sliding groove 26. During this process, the clamping block 47 enters the through slot 45 under the action of the spring. When the clamping tube 34 and the clamping rod 42 enter the sliding groove 26, the clamping block 47 extends to the outside of the clamping tube 34 through the through slot 45, and further makes the clamping rod 42 and the clamping tube 34 be clamped and connected. When the maintenance is completed, manually pull the extension line 41 to make the clamping tube 34 enter the gap between the combined groove 33 and the sliding groove 26 again, and synchronously relax the operating rod 4, causing the pressing plate 32 to descend. During the descent of the pressing plate 32, the combined groove 33 and the sliding groove 26 are gradually misaligned. Then, under the forced push of the pressing plate 32 and the guidance of the inclined surface at the bottom of the sliding groove 26, the clamping tube 34 enters the combined groove 33 again. And during the process of the clamping tube 34 entering the combined groove 33, the clamping block 47 gradually retracts into the telescopic groove 46. When the pressing plate 32 is reset, the end of the clamping block 47 enters the through slot 45. At this time, pulling the clamping block 47 forcefully can complete the separation of the clamping rod 42 and the clamping tube 34.

[0065] The end of the operating rod 4 is designed in a screw shape, and the open end of the fixed groove 3 is designed in a threaded groove shape. The operating rod 4 is threadedly connected to the fixed groove 3. The setting of the threaded connection between the operating rod 4 and the fixed groove 3 enables the operating rod 4 to enter the fixed groove 3 in a rotating and rising manner. And when the operating rod 4 is threadedly connected to the fixed groove 3, the staff does not need to continuously lift the operating rod 4, and can make the operating rod 4 hang on the fixed frame plate 2 temporarily, which is convenient for the staff to operate.

[0066] A hanging ring 5 is fixedly installed on the fixed frame plate 2. The hanging ring 5 is used to cooperate with a rope to connect to a fixed building. By setting the hanging ring 5, when installing the fixed frame plate 2, tie a rope to the hanging ring 5 and connect the other end of the rope to the fixed building, thereby realizing the suspension of the fixed frame plate 2, reducing the influence of the overall gravity of the device on the cable. At the same time, when disassembling and assembling the fault warning main body, it can reduce the influence of the pulling force on the cable and enhance the installation stability of the device on the cable.

[0067] A wire wheel 51 is rotatably installed on the operating rod 4. The extension line 41 is wound and installed on the wire wheel 51. A handle 52 is fixedly installed on the wire wheel 51. The settings of the wire wheel 51 and the handle 52 can facilitate the recovery and storage of the extension line 41.

[0068] A gravity block 53 is fixedly installed at the bottom of the fixed frame plate 2. In order to maintain the position of the fixed frame always vertically downward, the gravity block 53 is used to change the center of gravity of the fixed frame, so that the center of gravity is below the cable, and the fixed frame can always be vertically downward.

[0069] An elastic support ring 54 is fixedly installed on the operating rod 4. The elastic support ring 54 is larger than the bottom opening of the connecting groove 22. Since the operating rod 4 passes through the fault emergency main body through the connecting groove 22, it can guide the fault emergency main body during the descent process. The setting of the elastic support ring 54 is used to support and elastically buffer the fault emergency main body. Cooperating with the torsion spring hinge of the left end 1 and the right end 11, the fault emergency main body is unfolded and falls on the elastic support ring 54, so that it is convenient for the staff to repair without holding it by hand.

[0070] As Figure 11 shown, a usage method of a power grid equipment fault warning device, the usage method includes the following steps:
