Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution line fault detection, in particular to a power distribution line distributed fault positioning device. BACKGROUND

[0002] The distribution network fault refers to various faults occurring in the power distribution network, including short circuit, broken line, equipment failure and the like of overhead line. The occurrence of the distribution network fault is affected by various factors. Generally speaking, the larger the scale of the distribution network and the higher the degree of equipment aging, the higher the frequency of fault occurrence. In addition, there are also climate conditions, for example, under adverse weather conditions such as storm, lightning and the like, the distribution network is also prone to failure. According to statistics, the distribution network fault accounts for 80%~90% of the total fault of the power system, and the fault outage time caused by the distribution network accounts for 80% of the total outage time, so the distribution network fault monitoring needs to be strengthened. In the past, most areas still adopted the manual patrol as the main way to detect the fault, but with the emergence of the distributed traveling wave fault positioning technology of the distribution network, the distribution network fault monitoring problem has been effectively solved.

[0003] The power distribution line distributed fault positioning device is based on the traveling wave distance measurement technology, and through the distributed installation of the fault monitoring device on the overhead line of the distribution network, the traveling wave signal and the power frequency signal at the fault moment are collected and analyzed, so that the fault point can be quickly positioned. The fault information is sent to the monitoring system through the 4G / 5G / WIFI network and the like, and the system can also perform fault diagnosis through the deep artificial intelligence learning algorithm, and give early warning for the discharge signal caused by insulation abnormalities, so as to realize the online monitoring of the hidden danger of the distribution network line.

[0004] At present, the power distribution line distributed fault positioning device usually adopts the dual power supply mode of battery + solar panel to ensure the long-term operation of the device in the wild. The device is composed of two half-cylinder shells, the lower half is provided with various functional components, and the upper half shell is provided with a solar cell panel, which is covered with a transparent cover plate to absorb solar energy to power the battery. When installing the fault positioning device on the power distribution line, the device needs to be opened, the high-voltage line is clamped in the device, and then the device is closed and locked. The device is installed on the high-voltage line, which is a steel core aluminum stranded wire composed of multiple wires, and forms multiple spiral grooves on the surface. The device is provided with a clamp at both ends, and the clamp is provided with a rubber pad. The clamp at both ends fixes the high-voltage line, and the rubber pad seals the gap between the clamp and the high-voltage line.

[0005] Because the device is used in the field for a long time, it is blown by the wind and exposed to the sun, the high-voltage line is metal and easy to conduct heat, and the rubber pad is easy to age after long-term use, losing the fixing and sealing effect. If it encounters windy weather, the high-voltage line will sway, and the device will produce a small amount of rotational displacement. If the rotational displacement is accumulated for a long time, the device will rotate 180 degrees directly on the high-voltage line, and the solar panel will turn to the bottom, so that most of it cannot receive sunlight and lose the function of generating electricity and charging. If it encounters rainy weather, rainwater will seep into the device shell through the spiral groove on the high-voltage line. Since the shell is a closed cylindrical area, it is difficult for water to directly drain inside, and after long-term accumulation, it will corrode the components, causing the device to malfunction.

[0046] The working process of the technical scheme is as follows:

[0047] When installing the device, the worker first observes the spiral direction of the high-voltage line 18, separates the first shell 1a and the second shell 1b, then rotates the lower arc plate 8b, ensures that the direction of the anti-rotation plate 9 on the lower arc plate 8b corresponds to the spiral direction of the high-voltage line 18, adjusts the lower arc plate 8b, then places the second shell 1b below the high-voltage line 18, and the lower end surface of the high-voltage line 18 is attached to the inner wall of the lower arc plate 8b, then rotates the upper arc plate 8a, butts the upper arc plate 8a and the lower arc plate 8b, and tightens with screws. At this time, the anti-rotation plate 9 is deformed, the end of the anti-rotation plate 9 and one end of the waterproof fine strip are pressed into the arc-shaped groove of the high-voltage line 18, the upper arc plate 8a and the lower arc plate 8b are installed, the electronic components such as the power taking iron core and the Rogowski coil in the device are installed, finally the first shell 1a and the second shell 1b are closed, and are fixed by tightening with screws. Then a screwdriver and other tools are inserted into the butt joint groove 5a, the adjustment roller 5 is twisted, the water absorption belt 6 and the water absorption fine strip 6a are stretched into a taut state, and the installation is completed. In order to prevent the water absorption fine strip 6a from being broken, the adjustment roller 5 needs to be stopped when a certain resistance is encountered during twisting. When disassembling, the screwdriver and other tools are inserted into the butt joint groove 5a, the expansion rod 7d is pressed downward, the ratchet pawl 7e and the ratchet wheel 7b are disconnected, the screwdriver is reversed, the adjustment roller 5 releases the wound water absorption belt 6, and the water absorption belt 6 and the water absorption fine strip 6a become loose and curved. Then the first shell 1a and the second shell 1b are opened for disassembly.

[0048] When the device body 1 shakes with the high-voltage line 18 in windy weather, the anti-rotation plate 9 abuts in the arc-shaped slot of the high-voltage line 18, preventing the device from rotating on the high-voltage line 18, and at the same time, the water absorption strips 6a are in a straightened state, and the two water absorption strips 6 are connected to the high-voltage line 18 and the adjusting roller 5 in an inverted "8" shape, no matter which direction the body 1 rotates, the corresponding water absorption strip 6 will provide a pulling force to prevent the body 1 from rotating;

[0049] When it rains, rainwater seeps into the device along the arc-shaped slot of the high-voltage line 18, and encounters the water absorption strips 6a. Due to the capillary water absorption effect, the rainwater moves upward along the water absorption strips 6a and the water absorption strips 6. Since the humidity in the drying box 4 is very low, the moisture will continue to enter the drying box 4 along the water absorption strips 6 and be absorbed by the desiccant silica gel particles in the box. At the same time, since the water absorption strips are exposed inside the body 1, even if there is residual water vapor between the two housings, it will also be absorbed by the water absorption strips, and finally absorbed by the desiccant in the drying box 4. At the same time, since the exhaust hole 11 is open downward, the rain cover 14 is provided around the exhaust hole 11, rainwater cannot enter the device through the exhaust hole 11, and the solar radiation intensity is insufficient on rainy days, the temperature in the drying box 4 is relatively low, and the deformation temperature of the memory metal sheet 13 is not reached. The air hole 12a on the movable pipe 12 is located in the exhaust pipe 10, and the exhaust pipe 10 is not connected to the inside of the drying box 4, so external water vapor will not enter the drying box 4 through the exhaust pipe 10.

[0050] When it is sunny, the solar panel 3 continuously absorbs heat to power the built-in battery of the device, ensuring that the device can work in the wild for a long time. At the same time, the heat-absorbing coating on the surface of the drying box 4 also starts to absorb heat, and the drying box 4 rapidly heats up. When the solar radiation intensity is sufficient, the temperature in the drying box 4 can reach 90-120℃, heating and drying the silica gel particles in the box. Since the material of the drying box 4 is metal, the temperature rises quickly, the silica gel particles are dried, and the gas in the box is also rapidly heated and expanded, causing the memory metal sheet 13 to deform. The air hole 12a of the movable pipe 12 extends out of the exhaust pipe 10, and the exhaust pipe 10 is connected to the inside of the drying box 4. The air and water vapor in the box are discharged from the exhaust hole 11 to the outside of the device through the exhaust pipe 10.

[0051] In order to ensure that the temperature in the drying box 4 matches the memory metal sheet 13, a solar selective absorption coating is applied to the drying box 4. The coating method is magnetron sputtering film plating. In summer, when the solar radiation intensity is high, the temperature in the box reaches 120℃. On cloudy days, the solar radiation intensity is insufficient, and the temperature in the box is 70℃. In winter, when the solar radiation intensity is high, the temperature in the box reaches 90℃. On cloudy days, the solar radiation intensity is insufficient, and the temperature in the box is below 20℃. The memory metal sheet 13 is made of titanium-nickel alloy with a deformation temperature of 85℃.

[0052] The technical effects of the technical solution are as follows:

[0053] The anti-rotation plate 9 abuts the water absorption strip 6a in the spiral groove of the high-voltage wire 18, and the adjusting device 7 adjusts the water absorption belt 6 and the water absorption strip 6a to be straightened, in addition to the anti-rotation plate 9, which can prevent the body 1 from rotating on the high-voltage wire 18, one end of the water absorption strip 6a is fixed in the spiral groove of the high-voltage wire 18, and the straightened water absorption belt 6 and water absorption strip 6a also generate a certain tension, which strengthens the anti-rotation effect, even if the body 1 rotates slightly, it will reset under the action of tension, at the same time, the anti-rotation plate 9 presses the waterproof strip in the arc-shaped groove, and the rainwater seeps into the device along the arc-shaped groove of the high-voltage wire 18, and the moisture will continue to enter the drying box 4 along the water absorption strip and be absorbed by the drying agent. The technical solution can not only absorb the rainwater seeping into the spiral groove of the high-voltage wire 18 in time, but also can reinforce the position of the device to prevent the device from rotating; by setting the drying box 4, the memory metal sheet 13 and the exhaust pipe 10, in rainy weather, the air hole 12a of the movable pipe 12 is located in the exhaust pipe 10, which prevents external moisture from entering the drying box 4, after the drying box 4 absorbs the moisture inside the shell, in sunny weather, the heat absorption plate absorbs solar energy, the temperature of the drying box 4 rises rapidly, and the silica gel particles that absorb moisture are dried, at this time, the memory metal sheet 13 deforms, the gas in the drying box 4 expands under heat, the pressure increases, and the water vapor dried out is discharged from the exhaust hole 11 along the exhaust pipe 10, which utilizes solar energy to form a functional cycle of water absorption in rainy weather and water discharge in sunny weather.

[0054] It should be noted that the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other.
