Description

Technical Field

[0001] The present invention relates to the field of line protectors, in particular to a 10kV line protector with a gap. Background Art

[0002] As a crucial component of the power system, line protectors (P&Ds) have demonstrated the continuous advancement and development of power technology through their development history, classification, application, and technical characteristics. With the development of smart grids and the widespread adoption of new energy sources, P&Ds will play an even more crucial role, providing a strong guarantee for the safe and stable operation of power systems.

[0003] The invention patent with patent publication number CN 113708338 A discloses a line protector, including a connection box, the side wall of which is provided with an induction cavity and a sliding cavity, the inner wall of the sliding cavity is sealed and slidably connected to a slide, the side wall of one end of the slide is provided with a power connection plate, the side wall of the other end of the slide is connected to the inner wall of the sliding cavity by a compression spring, the inner wall of the induction cavity is sealed and slidably connected to a push block, the side wall of the push block is provided with a fixed plate, the side wall of the fixed plate is welded with a connecting rod, the connecting rod extends into the interior of the sliding cavity and abuts against the power connection plate.

[0004] In the above-mentioned invention patent, when there is an overcurrent in the circuit, the resistor will generate a large amount of heat. The evaporative liquid absorbs heat and evaporates, which can realize the separation of the connecting rod and the power board, realize the disconnection of the circuit, and play a protective role for the electrical appliance. By setting a compression spring in a compressed state, the connection between the power board and the connecting rod can be achieved when there is an overcurrent for a short time, thereby ensuring the normal use of the electrical appliance. However, when the line protector works in an icy and snowy environment, excessive accumulation of snow on the surface of the protector will cause the protector to be in a low temperature state, resulting in the evaporative liquid unable to absorb heat and evaporate normally, affecting the protective effect of the protector on the circuit. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a 10kV line protector with a gap, which solves the problems raised in the above background technology.

Pressing the buckle makes it rotate, and the rotating buckle releases the limit on the adjustment plate, and the installation position of the protector can be adjusted at this time.

[0007] Preferably, the turntable and the pressure plate are both foldable and can only be flipped upwards. In the early installation stage, the connection between the protector terminal and the transmission line is facilitated by flipping the turntable and the pressure plate upwards.

[0008] Preferably, the insert strip is plugged into the surface of the column, and the two are completely fitted together at the plug-in point. The scraper adopts a modular design and is disassembled when not in use, and will not block the connection between the power transmission line and the protector.

[0009] Preferably, the pressure plate is parallel to the turntable, and the pressure plate is driven to rotate when the turntable rotates.

[0010] Preferably, the surface of the adjusting plate is fixedly mounted with several protrusions, the top of the fixing rod is provided with an opening, the top of the fixing rod is rotatably mounted with a buckle, a second torsion spring is provided between the buckle and the fixing rod, the buckle passes through the opening on the surface of the fixing rod and contacts the protrusion, a connecting rod is slidably mounted on the surface of the fixing rod, a third spring is provided between the connecting rod and the fixing rod, a round table is sleeved on the surface of the connecting rod, the bottom of the round table is sleeved on the surface of the adjusting plate near the clamping ring, the bottom of the round table is provided with an inclined surface, a friction plate is slidably mounted on the surface of the clamping ring near the round table, a fourth spring is provided between the friction plate and the clamping ring, the shape of the friction plate is consistent with the shape of the clamping ring, when the position of the protector is adjusted, the friction plate moves to contact and fit with the line column, thereby increasing the friction force between the clamping ring and the line column, improving the support of the clamping ring to the protector, and avoiding the protector shaking and falling off when the position of the protector is adjusted.

[0011] Preferably, the connecting rod is movably connected to the circular table. No matter where the adjustment plate moves, the connecting rod is always connected to the circular table and can drive the circular table to move.

[0012] Preferably, the connecting rod is L-shaped, and the shorter end is located below the buckle. When the buckle is pressed to move the buckle, the buckle squeezes the connecting rod to move the connecting rod.

[0013] Preferably, a threaded rod is fixedly installed on the surface of the adjustment plate near the clamping ring, and an adjustment ring is threadedly installed on the surface of the threaded rod. The adjustment ring is fixedly installed on the end of the elastic spring away from the clamping ring. By moving the position of the adjustment ring on the surface of the threaded rod, the deformation degree of the elastic spring is changed, so that the elastic spring can provide different sizes of elastic force to the clamping ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The turntable and pressure plate in the 10kV gap line protector can prevent snow from directly covering the protector surface in snowy weather, and avoid the accumulated snow from accidentally touching the discharge head on the protector surface. The discharge gap between the discharge heads is connected in advance during the normal operation of the line, causing the normal operating current transmitted in the transmission line to be introduced into the ground through the protector, which can effectively prevent the accumulated snow from accidentally touching the discharge head, ensure the protection effect of the protector, and avoid false triggering.

[0016] (2) For the 10kV line protector with gaps, when the snow on the surface of the pressure plate accumulates excessively, the turntable will drive the pressure plate to rotate. The pressure plate will rub against the scraper during rotation, and the scraper will peel off the snow on the surface of the pressure plate. After the snow on the surface of the pressure plate is cleared, it will follow the turntable to reset under the elastic force of the first torsion spring, continue to block the snow for the protector, and prepare for the next snow cleaning work on the surface.

[0017] (3) The 10kV line protector with gap can release the limit of the adjustment plate by pressing the buckle to release the fixed rod, move the protector to adjust the protector to the working area, and adjust the position of the protector according to the length of the protected line section and different working conditions. When adjusting the protector, since the clamping ring clamps the line column, the protector is in a semi-fixed state, which is convenient for the staff to adjust. At the same time, during the adjustment process, the friction plate will contact the line column, increasing the friction between the clamping ring and the line column, and avoiding the protector shaking and falling off during the adjustment process.

[0018] (4) The 10kV line protector with gaps can move the adjusting ring on the surface of the threaded rod by rotating the adjusting ring, squeezing or dragging the elastic spring. The deformation of the elastic spring will change the elastic force on the clamping ring, and drag the clamping ring to rotate. According to the model and diameter of different line poles, the opening degree and the holding force of the clamping ring can be adjusted so that the protector can be fixed on the surface of different types of line poles, making the protector applicable to more working scenarios and improving the utilization rate.

The top of the stop cover 11 is completely fitted with the bottom of the eccentric box 10. A limit strip 12 is fixedly installed on the surface of the turntable 9. The limit strip 12 is fitted with the bottom of the stop cover 11. The end of the limit strip 12 away from the turntable 9 is set to an inclined plane. A slot 13 is opened on the surface of the turntable 9, and a slider 14 is slidably installed in the slot 13. A pressure plate 15 is fixedly installed on the top of the slider 14. A limit rod 16 is slidably installed on the surface of the column 8. A first spring is provided between the limit rod 16 and the column 8. The top of the limit rod 16 is released from the bottom of the slider 14, and the surface contacts the inner wall of the slot 13. An insert 17 is sleeved on the surface of the column 8. The insert 17 is L-shaped. A scraper 18 is slidably installed on the end of the insert 17 away from the column 8. A second spring is provided between the scraper 18 and the insert 17. Press the buckle 23 to rotate it. The rotating buckle 23 releases the limit on the adjustment plate 20, and the installation position of the protector can be adjusted at this time.

[0029] The turntable 9 and the pressure plate 15 are both foldable and can only be flipped upwards. In the early installation stage, the turntable 9 and the pressure plate 15 are flipped upwards to facilitate the connection between the protector terminal 2 and the transmission line.

[0030] The inserting strip 17 is plugged into the surface of the column 8, and the two are completely fitted at the plugging point. The scraper 18 adopts a modular design and is in a disassembled state when not in use, and will not block the connection between the transmission line and the protector.

[0031] The pressure plate 15 is parallel to the turntable 9 , and the pressure plate 15 is driven to rotate when the turntable 9 rotates.

[0032] The surface of the adjusting plate 20 is fixedly mounted with a number of protrusions 24, the top of the fixing rod 19 is provided with an opening, the top of the fixing rod 19 is rotatably mounted with a buckle 23, a second torsion spring is provided between the buckle 23 and the fixing rod 19, the buckle 23 passes through the opening on the surface of the fixing rod 19 and contacts the protrusion 24, the surface of the fixing rod 19 is slidably mounted with a connecting rod 25, a third spring is provided between the connecting rod 25 and the fixing rod 19, the surface of the connecting rod 25 is sleeved with a round table 26, the bottom of the round table 26 is sleeved on the surface of the adjusting plate 20 Near the clamping ring 21, an inclined surface is provided at the bottom of the cone 26, and a friction plate 27 is slidably installed on the surface of the clamping ring 21 near the cone 26. A fourth spring is provided between the friction plate 27 and the clamping ring 21. The shape of the friction plate 27 is consistent with the shape of the clamping ring 21. When the position of the protector is adjusted, the friction plate 27 moves to contact and fit with the line column, thereby increasing the friction force between the clamping ring 21 and the line column, improving the support of the clamping ring 21 for the protector, and avoiding the protector shaking and falling off when the position of the protector is adjusted.

[0033] The connecting rod 25 is movably connected to the round platform 26. No matter where the adjusting plate 20 moves, the connecting rod 25 is always connected to the round platform 26 and can drive the round platform 26 to move.

[0034] The connecting rod 25 is L-shaped, with the shorter end located below the buckle 23 . When the buckle 23 is pressed to move it, the buckle 23 squeezes the connecting rod 25 to move it.

[0035] A threaded rod 28 is fixedly installed on the surface of the adjustment plate 20 near the clamping ring 21, and an adjustment ring 29 is threadedly installed on the surface of the threaded rod 28. The adjustment ring 29 is fixedly installed on the end of the elastic spring 22 away from the clamping ring 21. By moving the position of the adjustment ring 29 on the surface of the threaded rod 28, the deformation degree of the elastic spring 22 is changed, so that the elastic spring 22 can provide different sizes of elastic force to the clamping ring 21.

[0036] Adjust the protector to the working height, clamp the clamping ring 21 on the surface of the transmission line pole, fix the protector, and ensure that the unpowered transmission line is on the surface of the protector terminal 2, determine the transmission line area that the protector needs to protect, adjust the distance between the protector and the line pole according to the size of the protected area, press the buckle 23 to rotate the buckle 23, and the rotating buckle 23 moves away from the adjustment plate 20 and no longer contacts the protrusion 24 on the surface of the adjustment plate 20, release the limit of the fixing rod 19 on the adjustment plate 20, push and pull the protector, and adjust the distance between the protector and the line pole. At the same time, when pressing the buckle 23, the buckle 23 rotates and squeezes the connecting rod 25 to move the connecting rod 25 downward, and the moving connecting rod 25 drives the round table 26 to move downward. The bottom inclined surface of the moving round table 26 squeezes and pushes the friction plate 27 on the surface of the clamping ring 21, so that the friction plate 27 moves toward the line pole. The moved friction plate 27 fits with the surface of the line pole, improving the clamping ring The friction between 21 and the surface of the line column prevents the protector from falling off due to the shaking of the clamping ring 21 when adjusting the position of the protector. After the protector completes its movement, the buckle 23 is released, and the buckle 23 returns to its original position and rotates under the elastic force of the second torsion spring. The rotated buckle 23 contacts the protrusion 24 on the surface of the adjusting plate 20 again, clamping the adjusting plate 20 to fix the protector. After adjusting the working area of ​​the protector, the cover plate 6 is covered on the transmission line on the surface of the terminal 2, and the fixing screws 7 on the cover plate 6 are aligned with the docking holes on the surface of the terminal 2 and tightened to connect the transmission line with the protector terminal 2, and the grounding terminal 3 at the bottom of the protector is connected to the grounding module on the surface of the line column. When the line is energized, the protector can effectively protect the line, which is convenient for the staff to install the protector, and the position of the protector can be reasonably adjusted according to the length of the protected line section to improve the protection effect of the protector on the line.

[0037] The adjusting ring 29 on the surface of the threaded rod 28 is rotated to move the adjusting ring 29 on the surface of the threaded rod 28. The moving adjusting ring 29 squeezes or drags the elastic spring 22 to cause the elastic spring 22 to contract and extend. When the elastic spring 22 contracts and extends, the clamping ring 21 can be driven to rotate to different degrees along the adjusting plate 20, and the position of the clamping ring 21 is adjusted to be suitable for line poles of different models and diameters. At the same time, after the elastic spring 22 is deformed, the elastic force between the clamping ring 21 and the adjusting plate 20 is changed, providing different sizes of elastic force for the clamping ring 21, so that the clamping ring 21 can clamp line poles of different models and diameters, so that the protector can be applied to more working scenarios, thereby improving the efficiency and flexibility of the protector.

[0038] When snow and ice weather comes, snowflakes will fall onto the surface of the protector of the prior art. When the snow on the surface of the protector is excessively accumulated, it will affect the working efficiency of the protector. It may also accidentally touch the first discharge head 4 and the second discharge head 5 on the surface of the protector, causing the two to be connected in advance, resulting in the normal working current transmitted in the power transmission line being introduced into the ground through the grounding terminal 3, affecting the normal operation of the power transmission line. The turntable 9 of the present invention is arranged above the protector, which can effectively prevent the snow from directly covering the protector. When the snow accumulates on the pressure plate on the surface of the turntable 9, the turntable 9 will be opened. When the eccentric box 10 is full of snow at this time, the gravity on the side of the eccentric box 10 is greater than that on the other side. Under the influence of the gravity difference on both sides, the turntable 9 is released. The limited turntable 9 rotates, and the rotating turntable 9 drives the pressure plate 15 to rotate. When the pressure plate 15 rotates, the snow on the surface will come into contact with the scraper 18. Under the reaction force, the scraper 18 pushes the snow on the surface of the pressure plate 15, so that the snow falls off the surface of the pressure plate 15. Because the turntable 9 and the pressure plate 15 are inclined, the snow will slide along the surface of the pressure plate 15, achieving the effect of cleaning the snow on the surface of the pressure plate 15. When the turntable 9 rotates, it drives the eccentric shaft box 10 and the blocking cover 11 to rotate. When the blocking cover 11 rotates to a position away from the limit When the snow on the surface of the pressure plate 15 and the inside of the eccentric box 10 is cleared, the gravity difference on both sides of the turntable 9 disappears, and the turntable 9 is reset and rotated under the elastic force of the first torsion spring. The reset turntable 9 drives the pressure plate 15, the eccentric box 10 and the baffle 11 to reset, and continues to block the snow for the protector and prepares for the next snow cleaning work.

[0039] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
