Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line maintenance, and in particular to a rapid isolation and maintenance device for power equipment. Background Art

[0002] Transmission lines are a vital component of the power system. Their primary function is to efficiently and safely transmit electricity generated by power plants to load centers or substations. Transmission lines typically consist of conductors, insulators, poles, towers, and hardware. These components work together to ensure stable and reliable power transmission over long distances. However, transmission lines can fail due to various reasons, such as lightning strikes, overloads, equipment aging, and external damage. Once a fault occurs, rapid isolation and power outage are necessary to prevent the fault from spreading, reduce the scope and duration of the outage, and ensure the safe and stable operation of the power system. Furthermore, to quickly restore power, transmission line maintenance is essential. Traditional methods of power outages, such as manually operated circuit breakers or disconnectors, suffer from slow response times and rely heavily on manual experience. In some emergency situations, faulty lines may not be disconnected in time, leading to widespread power outages and severe disruptions to residents and businesses. Moreover, traditional maintenance methods often require complex preparations and a long time to complete the maintenance tasks when inspecting transmission lines after a power outage, affecting the reliability and efficiency of power supply. In addition, with the continuous expansion of the scale of power systems and the demand for intelligent development, higher requirements are placed on the rapid isolation, power outage and maintenance of transmission lines.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] See also Figure 1 - Figure 11The present invention provides a technical solution: a rapid isolation device for power equipment, comprising an isolation box 1, a fixing plate 2 is installed at the bottom end of the isolation box 1, a fixing hole 3 is opened on the surface of the fixing plate 2, a photovoltaic panel 4 is installed on the top of the isolation box 1, and inspection ports are provided on the front and back of the isolation box 1. A baffle 5 is detachably installed at the inspection port by bolts, and openings 6 are opened at both ends of the isolation box 1. A first insulating pad 7 is installed at the top end of the interior of the isolation box 1, a first electric push rod 8 is installed at the bottom end of the first insulating pad 7, a mounting seat 9 is installed at the bottom end of the interior of the isolation box 1, and first insulators 10 are installed at both ends of the mounting seat 9, and conductive sheets 11 are installed at the tops of the two first insulators 10, a second insulating pad 12 is installed on one side of the interior of the isolation box 1, a second insulator 13 is fixedly installed on the surface of the second insulating pad 12, and a rotating seat 1 is fixedly installed on one side of one of the conductive sheets 11 4. A rotating shaft 15 is installed at the end of the second insulator 13, and the rotating shaft 15 is connected to the rotating seat 14. A first gate blade 16 and a second gate blade 17 are rotatably installed in the rotating seat 14 through the rotating shaft 15. The first gate blade 16 is fitted with the second gate blade 17. A first gate blade seat 18 is installed at the bottom of one end of the other conductive sheet 11. The first gate blade seat 18 clamps and fixes the first gate blade 16. A groove is provided on the surface of the mounting seat 9, and a metal gasket 19 is installed in the groove. A second gate blade seat 20 is installed on the surface of the metal gasket 19, and the second gate blade seat 20 clamps and fixes the second gate blade 17. The conductive sheet 11 connected to the rotating seat 14 is connected to the first gate blade 16 through a wire, and the metal gasket 19 is connected to the grounding wire 21. A pushing member 22 is installed at the telescopic end of the first electric push rod 8. A through hole is provided in the middle of the pushing member 22, and the first gate blade 16 is inserted into the through hole.

[0034] Specifically, after the fixing plate 2 is installed on the top of the tower or transmission frame through the fixing hole 3, the transmission lines at both ends are respectively connected to the two conductive plates 11. When the first switch blade 16 is closed with the first switch blade seat 18, the two transmission lines are connected, thereby realizing current conduction, and then realizing power transmission through the transmission line. The second switch blade 17 is closed with the second switch blade seat 20. Since the second switch blade seat 20 is connected to the metal gasket 19, and the metal gasket 19 is connected to the grounding wire 21, the device is made safer in this way. When a fault occurs in the transmission line, the first electric push rod 8 drives the pusher 22 to move downward, and the first switch blade 16 is inserted into the through hole in the middle of the pusher 22. Therefore, the pusher 22 will drive the first switch blade 16 to make an arc motion with the rotating shaft 15 as the center, thereby causing the first switch blade 16 to disengage from the first switch blade seat 18, thereby disconnecting the circuit in this way, and then the above method can achieve rapid isolation and power outage of the transmission line.

[0035] In this embodiment, an arc-extinguishing hood 23 is installed at the top of the mounting seat 9. The arc-extinguishing hood 23 is arranged directly below the first knife seat 18. When the first knife blade 16 detaches from the first knife seat 18, it enters the arc-extinguishing hood 23. The arc-extinguishing hood 23 is connected to the metal gasket 19.

[0036] Specifically, since the transmission line is a high-voltage line, an arc will be generated when the first switch blade 16 is detached from the first switch blade seat 18, and the arc will be pulled into the arc extinguishing grid of the arc extinguishing hood 23 under the action of the contraction force of the electromagnetic force. The arc extinguishing grid of the arc extinguishing hood 23 has a gap, so the arc will be divided into multiple short arcs after entering. When the AC current passes through zero, all short arcs will be extinguished. At the same time, the arc extinguishing grid of the arc extinguishing hood 23 will dissipate heat, and the arc will cool down quickly, thereby achieving the arc extinguishing effect.

[0037] In this embodiment, an L-shaped clip 24 is installed on the surface of the rotating shaft 15, and a mounting groove 25 is opened at the end of the clip 24. The first gate blade 16 is arranged in the mounting groove 25. A limit plate 26 is installed at the end of the clip 24. The limit plate 26 limits and fixes the first gate blade 16 in the mounting groove 25.

[0038] Specifically, the first gate blade 16 is placed in the mounting groove 25 and the first gate blade 16 is limited and fixed by the limiting plate 26, and the rotating shaft 15 is installed at the end of the second insulator 13. Therefore, in this way, when the pushing member 22 drives the first gate blade 16 to rotate, the rotation stability of the first gate blade 16 can be improved under the action of the clip 24, so that when the pushing member 22 drives the first gate blade 16 to close the first gate blade seat 18, the closing failure will not be caused by the displacement of the position of the first gate blade 16.

[0039] In this embodiment, the mounting seat 9 , the pushing member 22 , the clip 24 and the limiting plate 26 are all made of ceramic.

[0040] Specifically, the above method can effectively improve the safety of the device during use, and prevent the normal operation of the device from being affected by a short circuit caused by electrical conduction.

Guide holes are opened on the surfaces of the two corresponding vertical plates 306, and the guide rod 310 is inserted and installed in the guide holes.

[0043] Specifically, the servo motor 303 drives the reducer 302, so that the bidirectional screw 304 starts to rotate. When the bidirectional screw 304 rotates, the screw nut 305 on the surface drives the vertical plate 306 to move toward or away from each other. When the screw nut 305 moves toward each other, the transmission frame will be clamped between the corresponding insulating rollers 308. One of the insulating rollers 308 is connected to the drive motor 309, so the drive motor 309 drives the corresponding insulating roller 308 to rotate, so that the walking mechanism 30 can drive the support plate 29 to move along the transmission line, and then the robot arm 31 can maintain the transmission line fault.
