Description

Technical Field

[0001] The utility model relates to the technical field of lightning arrester leakage current detection, in particular to a lightning arrester leakage current detection device. Background Art

[0002] A lightning arrester is an electrical device used to protect power system equipment from overvoltage (such as lightning strikes, operating overvoltage, etc.). It is usually installed in parallel on key equipment (such as transformers, switchgear) or the ground side of transmission lines. It limits the voltage amplitude by "discharging" overvoltage energy. The tiny leakage current generated by the lightning arrester during normal operation or non-ideal conditions is called the leakage current. Abnormal increase may indicate equipment hidden dangers (such as aging, moisture), which need to be promptly checked through regular inspections (such as infrared temperature measurement, leakage current monitoring) to avoid system failures caused by lightning arrester failure.

[0003] However, the installation location of the lightning arrester (such as high altitude or narrow space) will lead to low efficiency of manual detection, and there will be problems such as blind detection areas, large environmental interference, and inability to conduct real-time dynamic tracking. This will cause safety hazards when the staff detect the downstream current of the lightning arrester, and will not be conducive to the safe operation of the staff. Therefore, a lightning arrester downstream current detection device is provided to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a lightning arrester leakage current detection device to solve the problem of potential safety hazards in the manual detection process due to the installation position of the lightning arrester in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A lightning arrester leakage current detection device comprises a bottom plate, universal wheels are fixedly mounted at four corners of the bottom surface of the bottom plate, and a mounting bracket is fixedly mounted on the upper surface of the bottom plate, a support seat is fixedly mounted on the middle of the mounting bracket, and the bottom end of the support seat is fixedly connected to the upper surface of the bottom plate, a rotating mechanism is mounted on the top of the mounting bracket, and a detection mechanism for detecting the leakage current is fixedly mounted on the top of the rotating mechanism;

[0007] The rotating mechanism includes a base fixedly installed on the top of the mounting bracket, a rotating ring gear is rotatably connected inside the base, a rotating gear is rotatably connected at one end inside the base, and the rotating gear and the rotating ring gear are meshedly connected, a rotating motor is fixedly installed at the bottom end of the base, and the output end of the rotating motor passes through the side wall of the base and is fixedly connected to the rotating gear.

[0008] By adopting the above technical scheme, when the arrester has a leakage current phenomenon, local overheating will occur. Therefore, temperature detection can be used to determine whether the leakage current phenomenon occurs based on the above phenomenon. However, due to the diversity of the installation positions of the arrester, some positions (higher positions, installation positions closer to the outside of the building, etc.) are more dangerous during the detection process, which is not conducive to the safe operation of the staff. Therefore, the setting of this device is used to solve the above problem. The mutual transmission cooperation of the rotating mechanism and the detection mechanism can realize the rapid detection of the arrester when the leakage current occurs, thereby improving the safety of the staff when performing the detection operation. The cooperation of the rotating mechanism and the detection mechanism can simulate the inspection of the arrester by the staff.

[0009] A further improvement of the technical solution of the utility model is that the rotating mechanism also includes a top cover fixedly installed on the top of the base, the inner ring of the top cover is rotatably connected to a rotating plate, and the lower surface of the rotating plate is fixedly connected to the upper surface of the rotating gear ring, a hydraulic cylinder is fixedly installed in the middle of the rotating plate, and the bottom end of the hydraulic cylinder is rotatably connected to the upper surface of the mounting bracket.

[0010] By adopting the above technical scheme, in the process of detecting the discharge current of the lightning arrester, it is necessary to quickly and adaptively adjust the direction of the detection mechanism so that the detection mechanism can detect the discharge current of the lightning arrester. In this process, the rotating motor drives the rotating gear and the rotating ring gear to rotate, and then drives the rotating plate and the hydraulic cylinder to rotate synchronously through the rotating ring gear. As the hydraulic cylinder rotates, the detection mechanism will follow the synchronous rotation, thereby realizing the adjustment of the direction of the detection mechanism. The setting of the rotating mechanism can quickly adjust the direction of the detection mechanism, which is convenient for the subsequent detection mechanism to detect the discharge current of the lightning arrester. The rotating mechanism of the rotating mechanism can adjust the direction of the device according to the actual installation position of the lightning arrester, thereby reducing the workload of the staff, simplifying the procedure of the detection process, and making it more convenient to detect the discharge current of the lightning arrester.

[0011] A further improvement of the technical solution of the utility model is that the detection mechanism includes a connecting frame fixedly installed on the output end of the hydraulic cylinder, a cross plate fixedly installed on the top of the connecting frame, mounting blocks symmetrically fixedly installed on the two ends of the upper surface of the cross plate, a servo moving device installed between the two mounting blocks, the output end of the servo moving device is transmission-connected with a sliding seat, the top of the sliding seat is fixedly installed with a mounting frame, the top of the mounting frame is fixedly installed with a mounting ring sleeve, the interior of the mounting ring sleeve is provided with a mounting groove, the bottom end of the mounting ring sleeve is fixedly installed with a working motor, the output end of the working motor is fixedly installed with a driving gear through the side wall of the mounting ring sleeve, and the driving gear is arranged inside the mounting ring sleeve, the interior of the mounting ring sleeve is rotatably connected with a rotating gear ring, and the driving gear is meshingly connected with the rotating gear ring, the bottom end of the rotating gear ring is fixedly installed with a connecting seat, and the top of the connecting seat is fixedly installed with a temperature measuring device.

[0012] By adopting the above technical solution, after the rotating mechanism completes the adjustment of the orientation of the detection mechanism, at this time, the servo moving device drives the sliding seat to move, and the position of the mounting frame and the mounting ring sleeve is adjusted by the movement of the sliding seat, so that the mounting ring sleeve is sleeved on the outside of the lightning arrester. Subsequently, the working motor drives the driving gear and the rotating gear ring to rotate, and then the connecting seat can be driven to follow the rotating gear ring to perform a large-scale circular arc motion along the mounting groove, and a temperature measuring device is fixedly installed on the top of the connecting seat. As the connecting seat moves, the temperature measuring device will rotate together. As the temperature measuring device rotates, the temperature measuring device can better detect the lightning arrester, and then the detection end of the temperature measuring device can be more accurately directed to the heating part of the lightning arrester, further improving the accuracy of the detection. The heating part of the lightning arrester can be quickly detected by the setting of the detection mechanism, and the large-scale circular arc motion of the detection mechanism can further improve the detection mechanism The positioning and capture of the heating part, thereby increasing the detection accuracy of the detection mechanism, the downward leakage current phenomenon of the lightning arrester is quickly detected by the mutual cooperation of the devices, and the detection process can be optimized while further improving the safety of the detection process, avoiding direct construction by the staff.

[0013] A further improvement of the technical solution of the utility model is that a fixing seat for protecting the temperature measuring device is fixedly installed on the top of the connecting seat.

[0014] By adopting the above technical solution, the fixing seat arranged at the top of the connecting seat can protect the temperature measuring device, so that the temperature measuring device can be protected during movement, further improving the safety of the device during operation.

[0015] A further improvement of the technical solution of the utility model is that a connecting plate which is mounted and matched with the connecting frame is fixedly installed at the output end of the hydraulic cylinder, a special-shaped protrusion which is mounted and matched with the connecting frame is arranged at the top end of the connecting plate, and a matching groove which is plugged and matched with the special-shaped protrusion is opened in the middle of the connecting frame.

[0016] By adopting the above technical solution, the connecting plate arranged on the top of the hydraulic cylinder can increase the connection area between the connecting plate and the connecting frame, further improve the fit between the two, and improve the stability of the device during operation, while the special-shaped protrusion on the top of the connecting plate and the matching groove on the connecting frame can further improve the fit between the two and increase the connection strength between the two.

[0017] A further improvement of the technical solution of the utility model is that sleeves are symmetrically provided on both sides of the hydraulic cylinder, and the bottom ends of the two sleeves are fixedly connected to the upper surface of the rotating plate, the two sleeves are internally slidably connected with connecting rods, and the top ends of the two connecting rods are fixedly connected to the lower surface of the connecting frame.

[0018] By adopting the above technical solution, the sliding fit between the sleeve and the connecting rod can increase the stability of the detection mechanism during lifting and lowering, further limit the lifting and lowering of the detection mechanism, and improve the operating stability of the device.

[0019] A further improvement of the technical solution of the utility model is that a counterweight block is fixedly installed at one end of the bottom of the transverse plate.

[0020] By adopting the above technical solution, the counterweight block arranged at the end of the horizontal plate can cooperate to adjust the balance of the detection mechanism, thereby further improving the stability of the device during operation.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model can quickly adjust the direction of the detection mechanism through the setting of the rotating mechanism, which is convenient for the subsequent detection mechanism to detect the discharge current of the lightning arrester. The rotating mechanism of the rotating mechanism can adjust the direction of the device according to the actual installation position of the lightning arrester, thereby reducing the workload of the staff, simplifying the procedure of the detection process, and making it more convenient to detect the discharge current of the lightning arrester.

[0023] 2. The utility model can quickly detect the heating part of the lightning arrester through the setting of the detection mechanism, and the large-range arc movement of the detection mechanism can further improve the detection mechanism's positioning and capture of the heating part, thereby increasing the detection accuracy of the detection mechanism. Through the mutual cooperation of the devices, the downward leakage current phenomenon of the lightning arrester can be quickly detected, and the safety of the detection process can be further improved while optimizing the detection process, avoiding direct construction by staff.

[0036] In this embodiment, when the arrester has a leakage current phenomenon, local overheating will occur. Therefore, temperature detection can be used to determine whether the leakage current phenomenon occurs based on the above phenomenon. However, due to the diversity of the installation positions of the arrester, some positions (higher positions, installation positions closer to the outside of the building, etc.) are more dangerous during the detection process, which is not conducive to the safe operation of the staff.

[0039] In this embodiment, in the process of detecting the discharge current of the lightning arrester, it is necessary to quickly and adaptively adjust the direction of the detection mechanism 6 so that the detection mechanism 6 can detect the discharge current of the lightning arrester. During this process, the rotating motor 10 drives the rotating gear 9 and the rotating ring gear 8 to rotate, and then drives the rotating plate 12 and the hydraulic cylinder 13 to rotate synchronously through the rotating ring gear 8.

The device 30 rotates, and the temperature measuring device 30 can better detect the lightning arrester, and then the detection end of the temperature measuring device 30 can be more accurately directed to the heating part of the lightning arrester, thereby further improving the detection accuracy. The heating part of the lightning arrester can be quickly detected through the setting of the detection mechanism 6, and the large-range circular motion of the detection mechanism 6 can further improve the positioning and capture of the heating part by the detection mechanism 6, thereby increasing the detection accuracy of the detection mechanism 6. Through the mutual cooperation of the devices, the downward leakage current phenomenon of the lightning arrester can be quickly detected, and the detection process can be optimized while further improving the safety of the detection process to avoid direct construction by the staff.

[0043] like Figure 4 , Figure 5 and Figure 6 As shown, preferably, a fixing seat 29 for protecting the temperature measuring device 30 is fixedly mounted on the top of the connecting seat 28 .

[0044] In this embodiment, the fixing seat 29 disposed at the top of the connecting seat 28 can protect the temperature measuring device 30, so that the temperature measuring device 30 can be protected during the movement, further improving the safety of the device during operation.

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, preferably, the output end of the hydraulic cylinder 13 is fixedly mounted with a connecting plate 14 which is mounted and matched with the connecting frame 17, the top end of the connecting plate 14 is provided with a special-shaped protrusion which is mounted and matched with the connecting frame 17, and the middle part of the connecting frame 17 is provided with a matching groove which is plugged and matched with the special-shaped protrusion.

[0051] In this embodiment, the counterweight block 31 disposed at the end of the transverse plate 18 can cooperate to adjust the balance of the detection mechanism 6 to further improve the stability of the device during operation.

[0052] The working principle of the arrester downstream current detection device is described in detail below.

[0053] like Figure 1-Figure 6As shown, when the arrester is inspected, the staff moves the device to a suitable working position, and then the rotating mechanism 5 and the detection mechanism 6 cooperate with each other to realize rapid detection of the arrester when a leakage current occurs, thereby improving the safety of the staff when performing the inspection operation;

[0054] During the detection of the lightning arrester's discharge current, it is necessary to quickly and adaptively adjust the direction of the detection mechanism 6 so that the detection mechanism 6 can detect the discharge current of the lightning arrester. During this process, the rotating motor 10 drives the rotating gear 9 and the rotating ring gear 8 to rotate, and then drives the rotating plate 12 and the hydraulic cylinder 13 to rotate synchronously through the rotating ring gear 8. As the hydraulic cylinder 13 rotates, the detection mechanism 6 will follow the synchronous rotation, thereby realizing the adjustment of the direction of the detection mechanism 6. The setting of the rotating mechanism 5 can quickly adjust the direction of the detection mechanism 6, which is convenient for the subsequent detection mechanism 6 to detect the discharge current of the lightning arrester. The rotating mechanism of the rotating mechanism 5 can adjust the direction of the device according to the actual installation position of the lightning arrester, thereby reducing the workload of the staff, simplifying the procedure of the detection process, and making it more convenient to detect the discharge current of the lightning arrester.

[0055] After the rotating mechanism 5 has adjusted the orientation of the detection mechanism 6, the servo moving device 20 drives the sliding seat 21 to move, and the position of the mounting frame 22 and the mounting ring 23 is adjusted through the movement of the sliding seat 21, so that the mounting ring 23 is sleeved on the outside of the lightning arrester.

As the connecting seat 28 moves, the temperature measuring device 30 will rotate together. By rotating, the temperature measuring device 30 can better detect the lightning arrester, and then the detection end of the temperature measuring device 30 can be more accurately directed to the heating part of the lightning arrester, thereby further improving the detection accuracy. The heating part of the lightning arrester can be quickly detected through the setting of the detection mechanism 6, and the large-range circular motion of the detection mechanism 6 can further improve the positioning and capture of the heating part by the detection mechanism 6, thereby increasing the detection accuracy of the detection mechanism 6. Through the mutual cooperation of the devices, the downward leakage current phenomenon of the lightning arrester can be quickly detected, and the detection process can be optimized while further improving the safety of the detection process to avoid direct construction by the staff.
