Among them, the single-phase grounding fault rate is as high as over 80%. In addition, the distribution lines are complex, the fault points are very hidden, manual troubleshooting is difficult, the processing cycle is long, and the power supply reliability is not guaranteed. In order to solve the problems existing in fault detection and positioning of traditional distribution networks, improve the efficiency and accuracy of fault handling, ensure the stable operation of the power grid, and meet the needs of the development of smart grids, an intelligent transmission and distribution network fault early warning management system is proposed.

It adopts distributed traveling wave detection technology and has the functions of fault location and hidden danger warning. The monitoring terminal looks like a square box and has the properties of rainproof, moisture-proof, corrosion-proof, vibration-resistant, lightning-proof, and electromagnetic interference-proof. It is installed on the conductors of overhead distribution lines with a card line structure. It can collect high-frequency fault currents and fault traveling wave currents generated by line faults and ground electric field signals in real time, and upload them to the monitoring center through a wireless network.
[0004] During the operation and use of the conventional intelligent power transmission and distribution network fault early warning management system, although its monitoring terminal has good stability in the early stage after fixed installation, with the increase of years of use, especially under the influence of external weather factors such as wind, rain and snow in mountainous areas, the transmission line sways, which is likely to cause the loosening of the fixed line structure, and thus may cause the displacement of the monitoring terminal. Especially when the line is broken due to severe weather such as rain, snow, and freezing rain, the displaced monitoring terminal is likely to detach along the line, causing damage to the monitoring terminal. Even if it is not detached from the line, it may hit the surface of the pole, causing damage to the monitoring terminal, which will affect the normal operation of the intelligent power transmission and distribution network fault early warning management system.

[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The present invention is provided with a wire-contacting driving wheel, a toothed pulley, a toothed belt, a driven wheel, a screw piston, a wire-clamping driven wheel, a liquid circuit, a liquid rod, a clamping plate, a movable shaft sleeve and a piston shaft tube. During installation, it can not only cooperate with the positioning structure configured by the device itself to perform flat-joint and fitting extrusion positioning of the distribution line, thereby avoiding irreparable dents on the surface of the distribution line caused by excessive reliance on the positioning structure, thereby affecting the normal service life of the distribution line, but also can avoid the situation where the positioning structure is cut when the device is active, and slide-guide and protect the surface of the distribution line. At the same time, according to the specific sliding situation when the device is active, the device can be adaptively matched to complete the emergency compression positioning on the surface of the distribution line, thereby preventing the stability of the device and the line from being affected by too small or too large extrusion force.
[0022] 2. The present invention arranges a line-contact driving wheel, a toothed pulley, a toothed belt, a driven wheel, a screw piston, a line-holding passive wheel, a liquid circuit, a liquid rod, a clamping plate, a movable sleeve and a piston shaft tube. When the upper structure and the lower structure of the fault warning management device are out of the positioning state and slide along the line where they are located, the rolling friction with the line surface is utilized to drive the line-contact driving wheel. The toothed pulley, the toothed belt and the combination of the toothed belt are used as the power to drive the screw piston to rotate, so that the liquid inside the specific channel is pushed in a threaded manner to act on the two ends and the inside of the line-holding passive wheel, so as to further press and clamp the line-holding passive wheel and the clamping plate to the power transmission line. This can prevent the equipment belonging to the intelligent power transmission and distribution network fault warning management system from being out of the broken line and crashing, and can also further enhance the safety and stability of the use of the intelligent power transmission and distribution network fault warning management system.
[0023] 3. The present invention can utilize the friction force sliding along the line to drive the driven wheel to rotate rapidly by means of the arrangement of a line-contacting driving wheel, a toothed pulley, a toothed belt, a driven wheel, a large gear, a small gear, a water drop wheel, an air pump, an air pump, a telescopic air bag, a telescopic air pipe and an air valve. Then, in combination with a combination of large and small gear groups, the low-frequency rotation is converted to a high-frequency rotation, so that the air pump is driven to move back and forth up and down, and during the movement, the air valve is cooperated to complete the inflation of the telescopic air bag. In this way, a layer of air cushion isolation can be provided at the bottom of the lower structure of the fault warning management device to prevent the power transmission line from accidentally breaking and hitting the surface of the line pole to cause damage. At the same time, the fault warning management device and the line pole can be insulated and isolated to prevent contact and conduction between the line and the line pole.
[0024] 4. The present invention provides a compression bag, a push switch and a warning light. After the telescopic airbag is inflated by introducing air, the compressed material inside the compression bag can expand rapidly and press against the surface of the push switch, thereby realizing the connection and power supply between the warning light and the internal circuit of the upper structure or the lower structure of the fault warning management device, and using the light to provide contact warnings around and light guidance at the fault location, so as to prevent the maintenance personnel from being affected by night or bad weather in locating the fault warning management device.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] See also Figures 1 to 9 , the present invention provides a technical solution for an intelligent power transmission and distribution network fault early warning management system:
[0041] An intelligent power transmission and distribution network fault early warning management system, comprising an upper structure 1 of a fault early warning management device and a lower structure 2 of the fault early warning management device, wherein the upper structure 1 of the fault early warning management device and the lower structure 2 of the fault early warning management device are fixedly connected to the power transmission and distribution line in a joint manner by a plurality of bolts, and are arranged at a position close to an electric pole, and further comprising a bottom buffer structure 3, wherein the bottom buffer structure 3 is fixedly installed at the bottom of the lower structure 2 of the fault early warning management device by a plurality of bolts;
[0042] The lower structure 2 of the fault warning management device includes a lower shell 201. A through hole for threading and positioning the wire is provided at the center of the upper surface of the lower shell 201, and two grooves are provided at intervals in the concave position inside the wire hole. A wire-attaching driving wheel 202 is connected to the groove near the wire outlet through a bearing. The wheel surface of the wire-attaching driving wheel 202 is slightly convex, and an arc-shaped groove with the same radius as the wire hole is provided on the wheel surface, so that it is more convenient to attach to the surface of the power transmission line. The shafts at both ends of the wire-attaching driving wheel 202 extend to the inside of the lower shell 201 and are connected to the same axis through the shaft. The toothed pulley 2021 connected to the lower shell 201 is fixedly connected, a toothed belt 203 is wound around the wheel body of the toothed pulley 2021, and the toothed belt 203 is connected to the driven wheel 204 located in the same longitudinal direction of the line entry groove, and a through-limiting slide groove is provided inside the driven wheel 204, and the driven wheel 204 is connected to the screw piston 2041 through the slide groove. The screw piston 2041 is composed of a limiting slide rod, a screw and a piston, and the screw part is threadedly connected to the threaded hole pre-opened in the same longitudinal direction of the line entry groove inside the lower shell 201, and the piston slides The piston shaft tube 2055 is connected to the U-shaped fluid channel opened at the output end of the threaded hole, and a piston shaft tube 2055 is slidably connected in the output channel of the U-shaped fluid channel. The upper end of the piston shaft tube 2055 is integrally connected to the bottom of the movable sleeve 2054, and a vertical through-hole is opened at the center position of the interior, and the hole extends upward to penetrate the movable sleeve 2054. A raised ring body is provided at the middle position of the inner ring surface of the movable sleeve 2054, and the movable sleeve 2054 is rotatably sleeved on the rotating shafts at both ends of the wire clamping passive wheel 205, and is limited by the ring body during the rotation process, and the wire clamping passive wheel 205 is moved by the movable sleeve 2054. The movable shaft sleeve 2054 is connected to the inside of the groove at the line entry end, and the rotating shaft surfaces at both ends of the line-clamping passive wheel 205 are provided with annular grooves larger than the thickness of the ring body at the ring body position of the movable shaft sleeve 2054, and the bottom surface of the annular groove is provided with a liquid path 2051 distributed along the axis core in an annular manner, which first extends toward the axis core direction, then extends along the axis core and finally passes from the axis core to the outside, and the inside of the liquid path 2051 is slidably connected with a liquid rod 2052, and the end of the liquid rod 2052 away from the axis core is integrally connected with a clamping plate 2053, and the upper edge of the clamping plate 2053 is flush with the arc groove on the side of the line-clamping passive wheel 205;
[0043] The driven wheel 204 is integrally connected with a large gear 2042 at the axial end opposite to the screw piston 2041. The large gear 2042 is movably connected to the space opened in the lower shell 201 through a bearing, and a small gear 2043 connected to the connecting space on one side is meshed for transmission. One axial end of the small gear 2043 is integrally connected with a water drop wheel 2044. The lower side surface of the water drop wheel 2044 is always in movably contact with the upper end of the air pumping rod 2045. A ball is fixedly installed on the upper end of the air pumping rod 2045, and a piston is fixedly installed on the lower end. A reset spring 2046 is sleeved on the rod body between the ball and the piston. The reset spring 2046 is limited by a ring plate integrally fixed on the rod body of the air pumping rod 2045, and the lower end of the reset spring 2046 is pressed against a hole groove pre-opened in the lower shell 201.
[0044] The upper structure 1 of the fault warning management device is different from the lower structure 2 of the fault warning management device, and does not include the large gear 2042, the small gear 2043, the water drop wheel 2044, the air pumping rod 2045 and the return spring 2046.
[0045] During operation, after a certain number of years of use, if severe weather conditions such as heavy rain, snow, freezing rain, etc. occur, causing the transmission line to sway or break, the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device may slide along the line due to strong centrifugal force. When the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device slide along the surface of the line, the friction of the line surface will drive the line-contacting active wheel 202 to roll, and the line-contacting active wheel 202 will simultaneously drive the toothed belt wheel 2021 to rotate, and the rotating toothed belt wheel 2021 will synchronously drive the driven wheel 204 through the toothed belt 203, and the driven wheel 204 will simultaneously drive the screw piston 2041 and the large gear 2042 to rotate, wherein the screw piston 2041 will be threadedly advanced along the threaded hole, and during the advancement process, it will push the liquid inside the pipeline where the screw piston 2041 is located to move, so that the liquid flows from one end of the U-shaped pipeline to the other. The movable sleeve 2054 drives the passive line-clamping wheel 205 to move, so that the wheel surface of the passive line-clamping wheel 205 gradually protrudes inside the line hole and further adheres to the power transmission line. During the movement of the passive line-clamping wheel 205, some liquid enters the liquid path 2051 from the hole in the center of the piston shaft tube 2055, and after gradually filling the liquid path 2051, it pushes the liquid rod 2052 to move along the hole from the inside to the outside, and the moving liquid rod 2052 pushes the clamping plate 2053 to gradually protrude from the inside of the passive line-clamping wheel 205. As the passive line-clamping wheel 205 and the clamping plate 2053 are pressed against the surface of the power transmission line, the line will be further stuck, thereby preventing the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device from continuing to slide along the line.
[0046] In summary, by configuring the line-sticking active wheel 202, the toothed pulley 2021, the toothed belt 203, the driven wheel 204, the screw piston 2041, the line-sticking passive wheel 205, the liquid circuit 2051, the liquid rod 2052, the clamping plate 2053, the movable sleeve 2054 and the piston shaft tube 2055, when the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device are out of the positioning state and slide along the line where they are located, the rolling friction with the line surface is used to drive the line-sticking active wheel 202, and this is used as the power. The screw piston 2041 is driven to rotate by utilizing the toothed pulley 2021, the toothed belt 203 and the combination of the toothed belt 203, so that the liquid inside the specific channel is pushed in a threaded manner to act on both ends and the inside of the wire-clamping passive wheel 205, thereby further pressing and locking the wire-clamping passive wheel 205 and the clamping plate 2053 to the transmission line. This can prevent the equipment belonging to the intelligent transmission and distribution network fault early warning management system from detaching from the broken line and crashing, and can also further enhance the safety and stability of the use of the intelligent transmission and distribution network fault early warning management system.
[0047] As an embodiment of the present invention, Figure 3 , 4 As shown in Figure 8, the bottom buffer structure 3 includes a telescopic airbag 301, and a telescopic air tube 3011 connected to the upper and lower walls is fixedly installed inside the telescopic airbag 301 on the same radial path of the inflation rod 2045, and the lower end of the inflation rod 2045 extends into the telescopic air tube 3011. The telescopic air tube 3011 is configured with three ports, wherein an air valve 3012 is fixedly installed at the pipe opening connected to the outside and the inside of the telescopic airbag 301, and the working modes of the two air valves 3012 are opposite, and the bottom surface below the inside of the telescopic airbag 301 is integrally connected with a A compression bag 3013, the interior of which is filled with a compressible material that expands upon contact with air, and a push switch 3014 is provided on the soft insulation below the compression material, the push switch 3014 is electrically connected to an electric control module inside an upper structure 1 of the fault warning management device or a lower structure 2 of the fault warning management device through a connecting line, and is electrically connected to a warning light 3015 fixed on the bottom surface of the telescopic airbag 301 through a connecting line extending downward through the telescopic airbag 301, the surface of the warning light 3015 is covered with a reinforced cover, and a lightning symbol is engraved on the surface of the cover.
[0048] During operation, the driven wheel 204 will coaxially drive the large gear 2042 to rotate, and the large gear 2042 will drive the small gear 2043 to rotate in a meshing transmission manner, and the small gear 2043 will coaxially drive the water drop wheel 2044 to rotate, and the water drop wheel 2044 will push the air pump rod 2045 downward through the undulating path on the surface, so that the air pump rod 2045 moves downward along the designated channel, and compresses the return spring 2046 during the downward movement, and the reciprocating up and down movement of the air pump rod 2045 will drive the piston at the lower end to suck the external gas into the telescopic air pipe 3011 through the air valve 3012, and push the gas through the air valve 3 012 enters the telescopic airbag 301, thereby inflating the telescopic airbag 301 and making it gradually inflate, thereby insulating and isolating the bottom of the lower structure 2 of the fault warning management device and providing elastic protection. Due to the influence of the air filling in the telescopic airbag 301, the compression material sponge, foam plastic, etc. inside the compression bag 3013 will expand to a certain extent and press against the surface of the push switch 3014, thereby achieving the connection of the circuit between the upper structure 1 of the fault warning management device or the lower structure 2 of the fault warning management device and the warning light 3015, and then the warning light 3015 will emit light to warn the surroundings.
[0049] In summary, by configuring the line-contacting driving wheel 202, toothed pulley 2021, toothed belt 203, driven wheel 204, large gear 2042, small gear 2043, water drop wheel 2044, inflating rod 2045, inflating rod 2045, telescopic airbag 301, telescopic air pipe 3011 and air valve 3012, the friction force sliding along the line can be used to drive the driven wheel 204 to rotate quickly, and then combined with the combination of large and small gear groups, the low-frequency rotation is converted to high-frequency rotation, so that the inflating rod 2045 is driven to move back and forth up and down, and during the movement, the air valve 3012 is cooperated to complete the inflation of the telescopic airbag 301, so that a layer of air cushion isolation can be performed at the bottom of the lower structure 2 of the fault warning management device to avoid transmission. When the electric line breaks accidentally, it hits the surface of the pole and causes damage. At the same time, the fault warning management device and the pole can be insulated to avoid contact and conduction between the line and the pole. Through the arrangement of the compression bag 3013, the push switch 3014 and the warning light 3015, after the telescopic airbag 301 is inflated by introducing air, the compressed material inside the compression bag 3013 can expand rapidly and press against the surface of the push switch 3014, so as to realize the connection and power supply between the warning light 3015 and the internal circuit of the upper structure 1 or the lower structure 2 of the fault warning management device, and use the light to warn the surrounding contacts and guide the light of the fault location, so as to avoid the maintenance personnel affecting the positioning of the fault warning management device at night or in bad weather.
[0050] Working principle: When working, first determine the installation location and method of the device according to the device's instruction manual and technical requirements. Generally speaking, the device should be installed at the key nodes of the distribution network to facilitate the monitoring of the entire network. The installation operation should be carried out according to the device's installation instructions, including fixing the device, connecting cables, etc. After the installation is completed, the device should be tested and debugged to ensure that the device operates normally and has early warning and positioning functions. After a certain number of years of use, if severe weather conditions such as heavy rain, snow, freezing rain, etc. occur, causing the transmission line to sway or break, the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device may slide along the line due to strong centrifugal force. If slippage occurs, the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device slide along the surface of the line, and the friction of the line surface will drive the line-contacting active wheel 202 to roll, and the line-contacting active wheel 202 will simultaneously drive the toothed belt wheel 2021 to rotate, and the rotating toothed belt wheel 2021 will synchronously drive the driven wheel 204 through the toothed belt 203, and the driven wheel 204 will simultaneously drive the screw piston 2041 and the large gear 2042 to rotate, wherein the screw piston 2041 will be threadedly advanced along the threaded hole, and during the advancement process, it will push the liquid inside the pipeline where the screw piston 2041 is located to move, so that the liquid flows out from one end of the U-shaped pipeline. Toward the other end, thereby pushing the piston shaft tube 2055 in the pipeline at the other end to move, and the piston shaft tube 2055 will push the movable sleeve 2054 along the pipeline, and the movable sleeve 2054 will drive the line-clamping passive wheel 205 to move, so that the wheel surface of the line-clamping passive wheel 205 gradually protrudes from the inside of the line hole and further adheres to the power transmission line. During the movement of the line-clamping passive wheel 205, some liquid will enter the liquid path 2051 from the hole in the center of the piston shaft tube 2055, and after gradually filling the liquid path 2051, it will push the liquid rod 2052 from the inside to the outside to move along the hole, and the moving liquid rod 2052 will push the clamping plate 2053 to gradually protrude from the inside of the line-clamping passive wheel 205. As the line-clamping passive wheel 205 and the clamping plate 2053 are pressed against the surface of the power transmission line, the line will be further stuck, thereby preventing the upper structure 1 of the fault warning management device and the lower structure 2 of the fault warning management device from continuing to slide along the line;During the above process, the large gear 2042 driven by the driven wheel 204 will drive the small gear 2043 to rotate in a meshing transmission manner, and the small gear 2043 will coaxially drive the water drop wheel 2044 to rotate. The water drop wheel 2044 will push the air pump 2045 downward through the undulating path on the surface, so that the air pump 2045 moves downward along the specified channel and compresses the return spring 2046 during the downward movement. The air pump 2045 that moves up and down reciprocatingly will drive the piston at the lower end to suck the external gas into the telescopic air pipe 3011 through the air valve 3012, and push the gas through the air valve 3012 into the telescopic air pipe 3011. The inside of the telescopic airbag 301 is compressed, so that the telescopic airbag 301 can be inflated and gradually expanded, and the bottom of the lower structure 2 of the fault warning management device is insulated and elastically protected. Due to the influence of the air filled in the telescopic airbag 301, the compression material sponge, foam plastic, etc. in the compression bag 3013 will expand to a certain extent and press against the surface of the push switch 3014, so that the circuit between the upper structure 1 of the fault warning management device or the lower structure 2 of the fault warning management device and the warning light 3015 can be connected, and then the warning light 3015 will emit light to warn the surrounding. ;
[0051] It should be noted that the contact surface between the line-contacting driving wheel 202 and the line has a certain degree of roughness, and the line can drive the line-contacting driving wheel 202 to rotate.
[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
