Description

Technical Field

[0001] This invention relates to the field of surge arrester technology, specifically to a surge arrester monitoring device. Background Technology

[0002] A surge arrester is an electrical device used to protect electrical equipment from high transient overvoltages and to limit the duration and amplitude of follow current. It is typically connected in parallel between the protected equipment and ground. Under normal operating voltage, it is in an insulating state. When lightning or switching overvoltage occurs, it quickly conducts, dissipating the overvoltage energy into the ground, thereby limiting the voltage amplitude and protecting the equipment's insulation. It quickly returns to its original state after the overvoltage disappears. To monitor the surge arrester's status, monitoring devices are installed around it to track its operation in real time. Most existing surge arrester monitoring devices have the functions of real-time monitoring of leakage current, recording of lightning strikes, providing fault warnings, and supporting remote communication and intelligent management. At the same time, the monitoring devices are equipped with counters and milliammeters so that staff can intuitively control the use of surge arresters. However, when the monitoring devices are installed at high altitudes, it is not convenient for staff to observe them from the ground. In addition, as the monitoring devices are placed outdoors for a long time, external dust and other substances will adhere to the monitoring devices, affecting the clarity of observation. At the same time, dust will also adhere to the surge arresters when they are placed outdoors. In a humid environment, dirt on the surface of the insulators will form a conductive layer, which will increase the leakage current and affect the monitoring accuracy of the surge arresters. Therefore, we propose a surge arrester monitoring device. Summary of the Invention

[0011] Optionally, the inner diameters of the second mounting hole and the first mounting hole are equal to the outer diameter of the threaded end of the screw hole.

[0012] This invention provides a surge arrester monitoring device, which has the following advantages: 1. This surge arrester monitoring device mounts the surge arrester monitor on a mounting plate. An inner protective shell, an outer protective shell, and a convex lens are fitted around the surge arrester monitor. The surge arrester body is monitored using the current transmission line and current transformer connected to the surge arrester monitor. The angle of the surge arrester monitor can be adjusted by rotating the rotating base and mounting plate, allowing ground personnel to easily view the monitored data.

[0013] 2. In this surge arrester monitoring device, when the controller detects that the surge arrester monitoring instrument has sensed the surge arrester in use, the controller controls the operation of the electric telescopic rod. The electric telescopic rod drives the rack to move laterally back and forth. Through the transmission between the rack, the first spur gear, the drive shaft, the second spur gear, and the internal gear ring, the air guide box, the second connecting steel pipe, and the blower pipe reciprocate on the outside of the surge arrester body. In addition, the movement of the rack causes the push-pull rod, the push-pull plate, and the first piston rod to drive the first piston plate to move back and forth in the inner cavity of the first air box. This allows the two first one-way valves to reciprocate to draw external air to both ends of the inner cavity of the first air box, and the two second one-way valves to reciprocate to discharge the air from both ends of the inner cavity of the first air box. The air is then introduced from the first connecting steel pipe, the first air guide steel pipe, the air guide box, and the air guide pipe into the blower pipe and ejected. The gas ejected from the blower pipe blows away the floating dust on the surge arrester body, preventing the dust on the surface of the insulator on the outside of the surge arrester body from forming a conductive layer in a humid environment, which would increase the leakage current and affect the monitoring accuracy of the surge arrester.

[0014] 3. When the push-pull plate moves, the second piston rod and the second piston plate move synchronously, causing the two third one-way valves to reciprocate to draw external air to both ends of the inner cavity of the second air filling box, and the two fourth one-way valves to reciprocate to discharge the air from both ends of the inner cavity of the second air filling box. The air is then introduced from the second connecting steel pipe, the second air guiding steel pipe, and the damping flexible pipe to the blower hood and sprayed out. The gas sprayed out by the blower hood blows away the floating dust on the outside of the convex lens, ensuring the clarity of the data observed by the personnel on the surge arrester monitoring instrument through the convex lens.

Dust filters can be installed at the bottom ends of the two third one-way valves 57 and the two first one-way valves 45. Units, such as filter cotton, prevent dust from entering. The bottom of the second air box 54 is fixedly sleeved with four one-way valves 58 at both ends. The two four one-way valves 58 can only allow the air inside the second air box 54 to enter and exit through the second connecting steel pipe 59. The two four one-way valves 58 are fixedly sleeved with the second connecting steel pipe 59.

[0023] Both the electrical box 1 and the bracket 2 are fitted with clamps 63, which consist of a U-shaped double-ended screw, a nut, a washer, etc., so as to install the electrical box 1 and the bracket 2 on the utility pole.

[0024] The multiple insertion holes 15 are evenly arranged in a circle with the axis of rotation of the rotating seat 18 as the center. The inner diameter of the insertion hole 15 is equal to the outer diameter of the threaded end of the wing screw 22, ensuring that the threaded end of the wing screw 22 can be inserted into each insertion hole 15, and ensuring the stability of the end of the wing screw 22 inserted into the insertion hole 15, thereby fixing the rotating seat 18, the mounting plate 19, and the surge arrester monitor 6 after angle adjustment.

[0025] The inner diameters of the second mounting hole 27 and the first mounting hole 29 are equal to the outer diameter of the threaded end of the screw hole 20, ensuring the stability of the screw hole 20 passing through the second mounting hole 27 and the first mounting hole 29, so as to stably install the surge arrester monitor 6 and the inner protective shell 23 on the mounting plate 19.

[0026] In summary, when using this surge arrester monitoring device, firstly, the electrical box 1 and bracket 2 are installed on the utility pole using clamps 63. Then, the bottom end of the surge arrester body 4 is inserted into the mounting hole 3 on the bracket 2 and secured with a nut. This positions the surge arrester body 4 inside the vent box 42. Simultaneously, a through-core current transformer 10 is fitted onto the bottom end of the surge arrester body 4, and a grounding wire 12 is connected. Furthermore, the surge arrester monitor 6 is placed on the mounting plate 19 on the side of the electrical box 1. An inner protective shell 23 and an outer protective shell 24 are fitted onto the outside of the surge arrester monitor 6. Hex bolts 30 are inserted into the first mounting hole 29 and the second mounting hole 27, with the threaded ends of the hex bolts 30 installed in the screw holes 20 to secure the surge arrester monitor 6. The current transmission line 11 on the side of the current transformer 10 is connected to the surge arrester monitor 6, and the current sensing line 14 on the controller 13 is also connected to the surge arrester monitor 6. Then, the wing screw 22 is rotated so that its end is disengaged from the inner cavity of one of the sockets 15, thereby releasing the fixing plate 21, the rotating seat 18 and the electrical box 1. Rotating the rotating seat 18 causes the mounting plate 19 and the surge arrester monitor 6 to rotate, so that the end of the surge arrester monitor 6 and the convex lens 25 are facing a position that is easy for the staff to observe on the ground. At this time, the wing screw 22 is aligned with the other socket 15, and the wing screw 22 is rotated so that its end is inserted into the other socket 15 to fix the fixing plate 21 and the rotating seat 18. At this time, the outer protective shell 24 is rotated. The distance between the convex lens 25 and the milliammeter, pollution meter, and action counter on the surge arrester monitor 6 is adjusted by the threaded engagement between the outer protective shell 24 and the inner protective shell 23. This allows the convex lens 25 to amplify the monitoring values ​​on the surge arrester monitor 6, making it easier for ground personnel to view. Then, when the surge arrester body 4 and the grounding wire 12 conduct high-voltage current to the ground, the current conducted on the surge arrester body 4 is sensed by the current transformer 10 and transmitted to the surge arrester monitor 6 through the current transmission line 11. The action counter on the surge arrester monitor 6 is activated, and the surge arrester monitor 6 receives current through the current sensing line 14. At this time, the controller 13 controls the electric telescopic pole 34 to operate once. Finally, when the electric telescopic rod 34 drives the rack 35 away from the mounting base 32, the meshing transmission between the rack 35 and the first spur gear 53 drives the transmission shaft 51 and the second spur gear 52 to rotate. The meshing transmission between the second spur gear 52 and the internal gear ring 41 drives the internal gear ring 41, the air box 42, the air pipe 49, and the blower pipe 50 to rotate around the outside of the arrester body 4. When the rack 35 and the first spur gear 53 drive once, the air pipe 49 rotates once around the arrester body 4. This is achieved through gear ratio matching, which will not be elaborated further. At the same time, the rack 35 drives the push-pull rod 36 and the push-pull plate 37 to move. The push-pull plate 37 pulls the first piston rod 38, the first piston plate 39, the second piston rod 56, and the second piston plate 55.When the first piston plate 39 moves within the inner cavity of the first inflation box 31, a first one-way valve 45 introduces external air into one end of the inner cavity of the first inflation box 31. Simultaneously, the first piston plate 39 draws air from the other end of the inner cavity of the first inflation box 31 through a second one-way valve 46, a first connecting steel pipe 47, a first air guide steel pipe 48, and an air guide box 42 into an air guide pipe 49. This causes the air in the air guide pipe 49 to be ejected from the blower pipe 50. The air, while rotating, blows out dust from the outside of the arrester body 4. When the second piston plate 55 moves within the inner cavity of the second inflation box 54, a third one-way valve 57 introduces external air. The air from one end of the second air box 54 is drawn through the second piston plate 55 to the other end of the second air box 54 via the fourth one-way valve 58, the second connecting steel pipe 59, the second air guide steel pipe 60, and the damping flexible pipe 61, and then blown out through the blower hood 62. The air blown out by the blower hood 62 is used to clean the dust on the outside of the convex lens 25. When the electric telescopic rod 34 drives the rack 35 to move in the opposite direction, the transmission between the rack 35, the first spur gear 53, the drive shaft 51, the second spur gear 52, and the internal gear ring 41 drives the air guide box 42 and the second connecting steel pipe 59 to rotate in the opposite direction. At this time, the rack 35 drives the push-pull rod 36. The push-pull plate 37 moves in the opposite direction to push the first piston rod 38, the first piston plate 39, the second piston rod 56, and the second piston plate 55. When the first piston plate 39 moves in the opposite direction inside the first air box 31, another first one-way valve 45 introduces external air into the other end of the first air box 31's inner cavity. The first piston plate 39 then guides the air from one end of the first air box 31's inner cavity through the second one-way valve 46, the first connecting steel pipe 47, the first air guide steel pipe 48, and the air guide box 42 into the air guide pipe 49, causing the air in the air guide pipe 49 to be ejected from the blower pipe 50. Similarly, the air is blown out while rotating. Air is used to blow away dust from the outside of the surge arrester body 4. When the second piston plate 55 moves in the reverse direction within the second inflation chamber 54, another third one-way valve 57 introduces external air to the other end of the second inflation chamber 54. The second piston plate 55 then uses the second piston plate 55 to guide air from the other end of the second inflation chamber 54 through the fourth one-way valve 58, the second connecting steel pipe 59, the second air guide steel pipe 60, and the damping flexible pipe 61 to the blower hood 62, which blows the air out again to clean the dust on the outside of the convex lens 25. This achieves the function of cleaning dust from the outside of the surge arrester body 4 and the convex lens 25.
