Description

Technical Field

[0001] This invention relates to the field of lightning strike fault detection technology, specifically to a method for monitoring and locating lightning strike faults in high-voltage lines. Background Technology

[0002] High-voltage lines generally refer to transmission lines that carry voltages of 10kV or higher. According to GB / T 2900.50-2008, definition 2.1 stipulates that high voltage usually does not include 1000V. The voltage levels of high-voltage transmission lines in China are generally divided into: 35kV, 110kV, 220kV, 330kV, 500kV, 750kV, etc. Since all lines at high altitudes are connected, if a high-voltage line is struck by lightning, it will cause the line to become unusable or unable to connect. At this time, lightning strike fault detection equipment is needed to detect the lightning strike condition to facilitate subsequent operation and maintenance.

[0003] When existing lightning strike fault detection devices are in use, a strong changing magnetic field and residual electricity are generated around the high-voltage output line when lightning strikes it. The strike can also damage high-voltage line components, causing them to fall. High-voltage lines are usually located high in the air, and without warning, passersby may be involved in serious safety accidents. Moreover, the location of the lightning strike is usually difficult to determine quickly after it occurs, which greatly reduces safety. Summary of the Invention

[0008] Preferably, the positioning mechanism includes a storage device, which is fixed to the rear side of the lower surface of the second mounting plate. An alarm light is installed on the front side of the lower surface of the second mounting plate. A fixing box is installed on the lower surface of the lightning strike fault detection device. An electromagnetic coil is installed inside the fixing box. The lower surface of the fixing box is fixed to the upper surface of the fixing plate. A sliding groove is formed on the lower part of the inner wall of the lightning strike fault detection device. Electromagnetic seats are installed on the front and rear sides of the inner wall of the sliding groove. Electromagnetic blocks are provided on the opposite side surfaces of the two electromagnetic seats. The two electromagnetic blocks are slidably connected to the lower surface of the sliding groove. Mounting slots are formed on the front and rear sides of the lower part of the inner wall of the sliding groove. Springs are installed on the lower part of the inner walls of the two mounting slots. Rotating plates are installed on the upper ends of the two springs. The opposite side surfaces of the two rotating plates are rotatably connected to the inner wall of the mounting slot through a rotating shaft.

[0009] Preferably, the alarm mechanism includes a smoke sensor, the lower surface of which is fixed to the front side of the upper surface of the second mounting plate, a photovoltaic panel is installed below the outer surface of the lightning strike fault detection device, a storage battery is installed on the rear side of the upper surface of the second mounting plate, the storage battery is electrically connected to the photovoltaic panel, and multiple alarm lights are installed below the front surface of the lightning strike fault detection device, the multiple alarm lights being connected in series via wiring.

[0010] Preferably, the first mounting plate has multiple air outlets on its rear side on the upper surface, and the first mounting plate is made of insulating material.

[0014] Preferably, the lightning strike fault detection device is provided in multiple sets, and the multiple lightning strike fault detection devices are respectively arranged above the corresponding fixed plates, and the internal structure of the multiple lightning strike fault detection devices is the same.

[0015] This invention also discloses a method for implementing a high-voltage line lightning strike fault monitoring device, specifically including the following steps:

[0016] S1. Lightning strike detection and positioning: First, the corresponding mounting bases are installed in the designated positions using multiple sets of thickened mounting bolts. Multiple lightning strike fault detection devices are installed above the designated locations, and multiple high-voltage lines are installed through multiple sets of fixing rings. When a lightning strike occurs near the line, the photovoltaic panels on the lightning strike fault detection device convert the light energy and solar energy absorbed inside into electrical energy to charge the battery through the lines. Moreover, after a lightning strike, a strong magnetic field is generated near the lightning strike fault detection device. At this time, a current is generated in the electromagnetic coil inside the fixing box, which charges the energy storage device through the wires.

[0017] S2, at this time, the rotating block supplies power to the two electromagnetic seats in the slide groove through the wire. Before this, the springs in the two mounting slots are in an uncompressed state, which can prevent the two electromagnetic blocks from attracting each other. Since the rotating block supplies power to the two electromagnetic seats in the slide groove through the wire, at this time, the corresponding set of electromagnetic seats and electromagnetic blocks repel each other on opposite sides, while the two electromagnetic blocks attract each other on opposite sides. The magnetic force will compress the two springs, so that the two rotating plates are in a horizontal state. When the attraction is completed, the two electrode plates contact each other, and then a path is formed between the wire and the GPS positioning device. The GPS positioning device quickly locates the lightning strike location through the background data, which is convenient for subsequent maintenance by the staff. Beneficial effects

[0018] This invention provides a method for monitoring and locating lightning strike faults in high-voltage power lines. Compared with existing technologies, it has the following advantages:

[0019] 1. This high-voltage line lightning strike fault monitoring and location method, through a mounting base, thickened mounting bolts, vertical rod, fixing plate, lightning strike fault detection device, fixing ring, rotating shaft, opening, and positioning mechanism, not only achieves rapid location of lightning strikes by connecting the lines between the electromagnetic base, electromagnetic block, GPS positioning device, battery, electromagnetic coil, and energy storage device, but also utilizes the natural wind force at high altitudes to capture the smoke generated after a lightning strike, thereby causing the alarm light in the alarm mechanism to flash to warn pedestrians to stay away. This solves the problem that high-voltage lines are generally located at high altitudes, and without warning, pedestrians passing by may cause serious safety accidents. Moreover, the lightning strike location is usually difficult to determine quickly after a strike, greatly reducing safety.

[0020] 2. This high-voltage line lightning strike fault monitoring and location method, through the setting of the air outlet, allows the smoke generated by the lightning strike to overflow through the air outlet, avoiding it from staying in the equipment and affecting its operation. Through the setting of the light-transmitting plate, and the fact that the light-transmitting plate is made of silicone material, it can not only protect the photovoltaic panel below, but also play a certain role in waterproofing without affecting the photovoltaic panel's absorption of light energy.

[0021] 3. This high-voltage line lightning strike fault monitoring and location method uses fixed blocks, windward plates, and spikes. The windward plates are made of acetal steel, which is slippery and can prevent birds from standing on the equipment and causing damage. By setting up multiple sets of lightning strike fault detection devices, each set of devices is spaced at the same interval, making the location of lightning strikes more accurate.

[0029] The technical solutions in the embodiments of the present invention have been clearly and completely described. 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.

[0030] Please see Figure 1-6 This invention provides a technical solution: a high-voltage line lightning fault monitoring device, including a mounting base 1. Multiple thickened mounting bolts 2 are provided on the upper surface of the mounting base 1. A vertical rod 3 is installed at the center of the upper surface of the mounting base 1. A fixing plate 4 is installed on the upper surface of the vertical rod 3. A lightning fault detection device 5 is installed on the upper surface of the fixing plate 4. Multiple fixing rings 6 are installed on the front side of the lower surface of the fixing plate 4 via multiple connecting rods. A high-voltage line is installed inside each of the multiple fixing rings 6. The lightning fault detection device 5 includes two rotating shafts 8, the rear ends of which are respectively connected to the lightning fault detection... The device 5 has a rotating connection on the left and right sides of the rear side of the inner wall. The upper surface of the lightning strike fault detection device 5 has an opening 7, and a rotating mechanism is set below the opening 7. The lightning strike fault detection device 5 has a positioning mechanism inside. It can not only quickly locate the lightning strike location by connecting the lines between the electromagnetic base 26, electromagnetic block 27, GPS positioning device 21, battery 18, electromagnetic coil 23, and energy storage device 24, but also capture the smoke generated after the lightning strike by the natural wind at high altitude, thereby causing the alarm light 20 in the alarm mechanism to flash to remind pedestrians on the roadside to stay away.

[0031] like Figure 1 and 2 As shown, multiple fixing blocks 33 are installed on the upper surface of the lightning strike fault detection device 5. Each fixing block 33 has spikes 34 installed on its upper surface. Multiple wind-facing plates 10 are made of acetal steel, which is slippery and can prevent birds from standing on the equipment and causing damage. A light-transmitting plate 32 is installed on the upper surface of the outer side of the lightning strike fault detection device 5. The light-transmitting plate 32 is made of silicone material, which can not only protect the photovoltaic panel 17 below it, but also play a certain role in waterproofing without affecting the photovoltaic panel 17's absorption of light energy. Multiple sets of lightning strike fault detection devices 5 are provided, and multiple lightning strike fault detection devices 5 are respectively set on the upper surface of the corresponding fixing plates 4. The internal structure of multiple lightning strike fault detection devices 5 is the same, which can make the lightning strike location more accurate.

[0032] like Figure 4 As shown, multiple air outlets 15 are provided on the rear side of the upper surface of the first mounting plate 14. The first mounting plate 14 is made of insulating material, which allows the smoke generated by lightning strikes to overflow through the air outlets 15, preventing it from remaining in the equipment and affecting its operation.

[0033] This invention provides a technical solution: a method for implementing a high-voltage line lightning strike fault monitoring device, specifically including the following steps:

[0034] S1. Lightning strike detection and positioning: First, install the corresponding mounting base 1 in the designated position using multiple sets of thickened mounting bolts 2. Multiple lightning strike fault detection devices 5 are installed on the designated fixing plate 4, and multiple high-voltage lines are installed through multiple sets of fixing rings 6. When a lightning strike occurs near the line, the photovoltaic panel 17 on the lightning strike fault detection device 5 converts the light energy and solar energy absorbed inside into electrical energy to charge the storage battery 18 through the line. Moreover, after a lightning strike, a strong magnetic field will be generated near the lightning strike fault detection device 5. At this time, a current will be generated in the electromagnetic coil 23 inside the fixing box 22, which will charge the storage device 24 through the wire.

[0035] S2, at this time, the rotating block 9 supplies power to the two electromagnetic seats 26 in the slide groove 25 through the wire. Before this, the springs 31 in the two mounting slots 29 are in an uncompressed state, which can prevent the two electromagnetic blocks 27 from being attracted. Since the rotating block 9 supplies power to the two electromagnetic seats 26 in the slide groove 25 through the wire, at this time, the corresponding set of electromagnetic seats 26 and electromagnetic blocks 27 repel each other on the opposite side, while the two electromagnetic blocks 27 attract each other on the opposite side. The magnetic force will compress the two springs 31, so that the two rotating plates 30 are in a horizontal state. When the attraction is completed, the two electrode plates 28 are in contact, and then a path is formed between the wire and the GPS positioning device 21. The GPS positioning device 21 quickly locates the lightning strike location through the background data, which is convenient for subsequent maintenance by the staff.

[0036] The alarm principle of this invention is as follows: Since multiple lightning strike fault detection devices 5 are located at high altitudes, when a lightning strike occurs, the lines are damaged and burned, producing smoke. At this time, the wind generated at high altitudes will cause multiple wind-facing plates 10 to rotate on the rotating block 9, thus driving the rotating shaft 8 to rotate inside the lightning strike fault detection device 5. The front end of the rotating shaft 8 will drive the suction fan 13 in the air intake channel 12 to rotate. The smoke from the vicinity will enter the air intake channel 12 through the air inlet 11. The smoke enters below the first mounting plate 14 and is captured by the smoke sensor 19 on the surface of the second mounting plate 16, causing multiple alarm lights 20 to flash. A buzzer can also be installed here for use. The flashing red light of the alarm lights 20 can warn nearby passersby that a lightning strike has occurred nearby and they should not approach.

[0037] The lightning strike fault detection device 5 is equipped with multiple fixing blocks 33, and multiple spikes 34 are installed on the multiple fixing blocks 33. The multiple spikes 34 can prevent some flying birds from flying onto the equipment and affecting the operation of the equipment. When birds see the barbs on the multiple spikes 34, they naturally dare not land on the equipment, thus playing a role in repelling them.

[0038] Finally, it should be noted that the corresponding electromagnetic bases 26 and electromagnetic blocks 27 have the same magnetic poles on opposite sides, while the two electromagnetic blocks 27 have opposite magnetic poles on opposite sides. The right electrode 28 is connected to the GPS positioning device 21 via a wire, and the GPS positioning device 21 is connected to the positive terminal of the battery 18 via a wire. The left electrode 28 is connected to the negative terminal of the smoke sensor 19 via a wire. When the two electrode 28 come into contact, the circuit is connected. At this time, the computer backend can receive the lightning strike location information transmitted by the GPS positioning device 21, which is convenient for subsequent inspection and maintenance. Under normal conditions, the magnetic force generated between the corresponding electromagnetic bases 26 and electromagnetic blocks 27 is insufficient to compress the two springs 31, so the two electrode 28 cannot come into contact. The smoke sensor 19 can be energized through the branch of the wire connected to the battery 18 to detect smoke and transmit a signal to the alarm light 20, which in turn causes the alarm light 20 to flash.
