Description

Technical Field

[0001] The present invention relates to the field of electric power, and more particularly to a discharge device. Background Art

[0002] Electricity is an energy production and consumption system consisting of power generation, transmission, transformation, distribution and consumption. The transmission is completed by the high-voltage power grid. In case of failure, maintenance and other situations, the high-voltage power grid needs to be shut down for maintenance. Generally speaking, after the high-voltage power grid is out of power, there may be residual charge or energy on the high-voltage line. If it is not discharged, it may have adverse effects on the surrounding personnel and equipment. For example, discharge may cause electric shock to personnel, damage to equipment or facilities, etc. Therefore, the high-voltage power grid needs to be discharged first after power outage to ensure safety and reliability before maintenance work can be carried out. The high-voltage discharge rod is a device used by power workers to discharge the high-voltage power grid. The existing high-voltage discharge rod is mainly composed of an insulating rod, a discharge rod, and a discharge rod. It consists of a tip, a discharge hook, a release resistor, a grounding wire, etc., wherein the discharge tip is fixed on the end face of the insulating rod, the discharge hook is fixed on the side of the insulating rod, the discharge tip is connected to the grounding wire through the release resistor and the socket, and the discharge hook is connected to the grounding wire through the same socket. When discharging, hold the insulating rod and move slowly, so that the discharge tip slowly approaches the high-voltage cable, and it first discharges freely through the gap air. At this time, a hissing sound can be heard. When there is no sound, touch the high-voltage cable with the discharge tip, and then hook the discharge hook on the cable for secondary discharge. The discharge time is affected by the voltage level, cable length, temperature, etc. Generally speaking, the discharge time of the high-voltage cable after a power outage is generally between several hours and several days.

[0003] However, the discharge tip and discharge hook on the existing high-voltage discharge rod are directly exposed to the outside, which is easy to injure power workers during transportation and handling, has low safety, is easily deformed under the action of external forces, has a short service life, and power workers rely entirely on their hands to control the discharge tip to slowly approach the high-voltage cable, which is difficult to control the approach speed. It is also extremely time-consuming and labor-intensive and difficult to operate. Therefore, there is an urgent need to design a discharge device. Summary of the invention

[0044] Working principle:

[0045] First, insert the ground wire into the ground wire socket 15, then rotate the movable ring 33, and then the movable ring 33 rotates with the external thread ring 34, and then the external thread ring 34 moves upward under the action of the thread cooperation between it and the internal thread ring groove 32, and then the external thread ring 34 moves upward with the movable ring 33, and then the external thread ring 34 is separated from the internal thread ring groove 32, and then an upward thrust is applied to the movable ring 33, and then the movable ring 33 moves upward with the linkage slide 36 through the guide ring groove 35, and then the linkage slide 36 slides upward inside the guide strip hole 37, and then the linkage slide 36 moves upward with the insulating platform 38, and then the insulating platform 38 moves upward with the discharge hook 17, and at the same time, the insulating platform 38 moves upward on the outside of the conductive long rod 25 The insulating platform 38 moves upward with the conductive ring 809 through the torsion chamber 808, and then the top of the discharge hook 17 passes through the hook receiving hole 39, and then the external threaded ring 34 at the top of the moving ring 33 is inserted into the internal threaded ring groove 32 at the top of the receiving ring groove 31, and then the moving ring 33 is rotated, and then the moving ring 33 rotates with the external threaded ring 34, and then the external threaded ring 34 enters the internal threaded ring groove 32 under the action of the threaded fit between it and the internal threaded ring groove 32, and then the extended state of the discharge hook 17 is fixed, and then the discharge hook 17 is hooked on the high-voltage cable, and then the discharge device is moved downward under the action of gravity, and then the high-voltage cable adjusts the position of the discharge hook 17 through the surface of the discharge hook 17, and then the discharge hook The two inner sides of the sub 17 are in contact with the high-voltage cable to achieve calibration. At this time, the discharge tip 16 is aligned with the high-voltage cable, and then an upward thrust is applied to the binding ring 63, and then the binding ring 63 moves upward and is pulled out of the binding notch 65, and then the flipping arm 54 is released, and then the traction spring 56 applies a pulling force to the traction arm 57, and then the traction arm 57 brings the flipping arm 54 to flip outward with the flip short axis 53 as the center axis, and then the inner wall of the flip side groove 52 blocks the flipping arm 54. At this time, the flipping arm 54 flips ninety degrees, and then the binding ring 63 is released, and then the upper magnetic ring 62 applies a magnetic thrust to the lower magnetic ring 64, and then the lower magnetic ring 64 pushes the binding ring 63 to move downward, and then the binding ring 63 is in the binding ring groove 61 The first threaded rod 405 is moved downward to the extreme position, and then one hand holds the insulating handle 11, and the other hand applies a flipping force to the flipping arm 54, and then the flipping arm 54 rotates with the driving short column 403 through the flipping short shaft 53 and the flipping side groove 52, and then the driving short column 403 rotates with the rotating short column 402 relative to the insulating handle 11, and then the rotating short column 402 rotates synchronously with the internal threaded tube 404, and then the plug-in action between the anti-rotation plug plate 406 and the near-angle cavity 401 restricts the external threaded rod 405 so that it cannot rotate, and then the external threaded rod 405 rotates relative to the internal threaded tube 404, and then the external threaded rod 405 moves upward under the action of the threaded cooperation between it and the internal threaded tube 404, and then the external threaded rod 405 moves upward with the anti-rotation plug plate 406,Then, the anti-rotation plug plate 406 moves upward with the lower column 407, and then the lower column 407 moves upward against the anti-rotation displacement plate 410, and then the anti-rotation displacement plate 410 moves upward with the upper column 411, and then the upper column 411 pushes the tip storage square column 24 to move upward. During this process, the insulating plug plate 75 applies a thrust to the conductive slide bar 76 under the action of the elastic force of the pre-compression spring 74, so that the end of the conductive slide bar 76 is always slidably connected with the surface of the contact conductive bar 77, and then the tip storage square column 24 moves upward with the conductive long rod 25 through the conductive short column 801, the insulating elastic member 803, and the conductive slide column 804, and then the conductive long rod 25 moves upward with the discharge tip 16, and then the discharge tip 16 gradually approaches the high-voltage cable, driving The faster the driving short column 403 rotates, the faster the discharge tip 16 approaches the high-voltage cable; the slower the driving short column 403 rotates, the slower the discharge tip 16 approaches the high-voltage cable; the rotation speed of the driving short column 403 is controlled as needed, and then the electric energy on the high-voltage cable is discharged freely through the gap air between the discharge tip 16 and the high-voltage cable; then the discharge tip 16 transmits the electric energy to the grounding wire through the conductive long rod 25, the conductive sliding column 804, the torsion boss 806, the conductive short column 801, the release resistor 18, the conductive sliding bar 76, the contact conductive bar 77, and the grounding socket 15, and the grounding wire realizes the discharge; then the discharge tip 16 is against the surface of the high-voltage cable, and then the high-voltage cable applies a reverse thrust to the discharge tip 16, and then the discharge tip 16 is passed through the conductive long rod 25, the conductive sliding column 804, the torsion boss 806, the conductive short column 801, the release resistor 18, the conductive sliding bar 76, the contact conductive bar 77, and the grounding socket 15. The conductive long rod 25 moves the conductive slide column 804 to the inside of the plug-in column groove 802, and then the conductive slide column 804 squeezes the insulating elastic member 803, the insulating elastic member 803 is elastically compressed, and the elastic potential energy increases, and then the torsion boss 806 slides inside the torsion slot 805, and then the torsion boss 806 applies a turning force to the conductive slide column 804 through the inner wall of the torsion slot 805, and then the conductive slide column 804 turns over with the overlapping lower spring bar 807 and the conductive long rod 25, and then the conductive long rod 25 turns over synchronously with the overlapping upper spring bar 812 through the plug-in effect between the synchronous slot ring 810 and the conductive boss 811, and the conductive ring 809, and then the overlapping lower spring bar 807 contacts the contact conductive bar 77, and at the same time, the overlapping upper spring bar 812 contacts the release The electric hook 17 contacts, at which time the tip storage square column 24 moves upward to the extreme position, and the rotation of the driving short column 403 stops. Then the electric energy on the high-voltage cable is released through the discharge hook 17, the overlapping upper spring bar 812, the conductive ring 809, the conductive boss 811, the conductive long rod 25, the conductive slide column 804, the overlapping lower spring bar 807, the contact conductive bar 77, the grounding socket 15, and the grounding wire to achieve secondary discharge. After the discharge work and maintenance work are completed, when the discharge device needs to be disassembled, the driving short column 403 is rotated in the opposite direction, and then the tip storage square column 24 moves downward under the elastic tension of the tip storage spring 23, and then the conductive slide column 804 moves out from the inside of the plug-in column slot 802 under the elastic force of the insulating elastic member 803.Then, the torsion boss 806 applies a thrust to the inner wall of the torsion slot 805, and then the conduction slide 804 flips in the opposite direction, and then the conduction slide 804 flips in the opposite direction with the overlapping lower spring bar 807, the conduction long rod 25, the synchronous slot ring 810, the conduction boss 811, the conduction ring 809, and the overlapping upper spring bar 812, and then the overlapping lower spring bar 807 is separated from the contact conduction bar 77, and the overlapping upper spring bar 812 is separated from the discharge hook 17, and then the torsion boss 806 moves downward to the extreme position inside the torsion slot 805, and then the conduction short column 801 moves downward with the conduction slide 804 through the plug-in effect between the torsion boss 806 and the torsion slot 805, and then the conduction slide 804 moves downward with the discharge tip 16 through the conduction long rod 25, and then the discharge tip 16 retracts into the tip storage hole 26, and then the restraining ring 63 moves upward to completely release the flip side groove 52, and then the flip force arm 54 is flipped to make The flipping force arm 54 is inserted into the flipping side groove 52, and then the binding ring 63 is released. The binding ring 63 moves downward under the action of magnetic repulsion and is inserted into the binding notch 65, limiting the flipping force arm 54 inside the flipping side groove 52. In this process, the flipping force arm 54 pulls the traction spring 56 through the traction arm 57, and the traction spring 56 is elastically stretched, and the elastic potential energy increases. Then the discharge hook 17 is removed from the high-voltage cable, and then the shifting ring 33 is rotated to separate the external thread ring 34 from the internal thread ring groove 32, and then the shifting ring 33 is moved downward with the insulating platform 38 through the linkage slide 36, and then the insulating platform 38 moves downward with the discharge hook 17, and then the discharge hook 17 is retracted into the hook receiving hole 39, and then the external thread ring 34 at the bottom of the shifting ring 33 enters the internal thread ring groove 32 and is threadedly matched, and the discharge hook 17 is fixed inside the hook receiving hole 39, and then the discharge device is transferred.
