Description
Technical Field
[0001] The utility model relates to the technical field of arrester leakage current test, in particular to an auxiliary component based on arrester leakage current test. Background Art
[0002] The arrester resistive leakage current detector is an instrument used to measure resistive current, so as to analyze the degree of aging and moisture of zinc oxide. It can also be used as an instrument for factory and acceptance tests in laboratories. The current passing through the zinc oxide resistor is called the leakage current of the zinc oxide arrester, which is also considered to be the total leakage current of the arrester. Under normal rated power frequency voltage, the arrester can be regarded as an insulator. The leakage current can reflect the insulation condition of the arrester and is an important means to judge the quality of the arrester under the operating voltage.
[0003] The current arrester test can sensitively detect degraded arresters, but due to the constraints of the surrounding environment of the substation site, it is impossible to achieve the same test conditions as the manufacturer. During the test, it may happen that the value cannot be measured or the test data is abnormal, and multiple adjustments are required until accurate data is measured. Abnormal test data will occur. When the test abnormality occurs, it will cause the test personnel to repeat work, seriously affecting the test efficiency. The higher the voltage level of the arrester, the longer the body and the induced voltage increase. In addition, some arrester leads use tube-type wiring. The removal of high-voltage leads requires the use of lifts, cranes and other facilities, which requires a large workload, a long time to disconnect and connect, and a high cost, and poses a certain threat to personal and equipment safety.
[0004] A Chinese patent document discloses an auxiliary device for lightning arrester leakage current test (Announcement No. CN115453179A), which includes a housing, a mounting plate, a rotary switch, a grounding terminal, a measuring terminal, a first resistor, a second resistor, and a measuring microammeter. The mounting plate is mounted on the housing, and the rotary switch, the grounding terminal, the measuring terminal, the first resistor, the second resistor, and the measuring microammeter are mounted on the mounting plate; however, the following defects still exist in the implementation process:
[0005] Although the device in the above-mentioned document can minimize the size of the device, is easy to carry, and performs reasonable wiring and internal space allocation to optimize the internal heat dissipation environment of the device, avoid system instability caused by overheating, and can achieve free switching of 0 megohm, 5 megohm, and 10 megohm resistance values, the device in the above-mentioned document has certain limitations when used in emergency situations. During the lightning arrester leakage current test, if there is a sudden strong wind or rain or other weather that is not suitable for the test, the connecting wires built outdoors at high altitude cannot be disconnected in time, and the wiring is easily shaken by wind and falls off, or eroded by rain, threatening the safety of personnel and equipment, and reducing the accuracy of the test results.

[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

Specifically, the inclined surfaces on both sides of the extruded conical plate are set. When the magnetic joint is connected to the arrester, the push plate is squeezed to make the third spring behind it contracted. When the electromagnetic lock inside the magnetic joint is disconnected, the force applied by the magnetic joint to the push plate is reduced. At this time, the third spring is reset and pushes the push plate and the extruded conical plate to move in the fixed frame, and pushes the magnetic joint to completely disconnect from the arrester. Therefore, the connection between the two can be disconnected in time in the fastest time, thereby improving the safety of detection.

At the same time, under the action of the second spring, the impact of the wind on the connecting line is buffered, thereby improving the stability of the connecting line during the test, and further improving the safety of the test and the accuracy of the data.

[0035] The utility model is further described in detail below in conjunction with the embodiments.
[0036] Example 1
[0037] like Figure 1 , Figure 2 and Figure 6 As shown, the utility model provides an auxiliary component based on the arrester leakage current test, including a detection body 1; the output end of the detection body 1 is connected to a voltage multiplier cylinder 2 through a wiring harness, the top of the voltage multiplier cylinder 2 is detachably connected to a connecting wire 5, the outer wall of the voltage multiplier cylinder 2 is fixedly connected to a first support seat 4, the connecting wire 5 and the first support seat 4 are slidably connected, the end of the first support seat 4 close to the voltage multiplier cylinder 2 is fixedly connected to an arc-shaped baffle 7, the end of the first support seat 4 away from the arc-shaped baffle 7 is fixedly connected to a conical protective cover 6, the end of the connecting wire 5 away from the voltage multiplier cylinder 2 is fixedly connected to a magnetic suction joint 20, an electromagnetic lock is arranged inside the magnetic suction joint 20, and a protective component is arranged outside the magnetic suction joint 20, and the protective component is used to assist the magnetic suction joint 20 to detach from the lightning arrester.
[0038] In this embodiment, the magnetic connector 20 is provided to connect with the lightning arrester, and the leakage current is detected in cooperation with the detection body 1 and the voltage multiplier cylinder 2. One end of the connecting line 5 passes through the first support seat 4 and is connected with the voltage multiplier cylinder 2. The conical protective cover 6 and the arc baffle 7 at both ends of the first support seat 4 are arranged in an arc shape, which limits the swinging and floating of the connecting line 5 while protecting the surface of the connecting line 5, avoiding damage to the connecting line 5 caused by friction with the first support seat 4 due to wind. In response to sudden severe weather, the protective component is used to disconnect the connection with the lightning arrester to improve safety.
[0039] Preferably, Figure 6 , Figure 7 and Figure 8 As shown, the protective component includes a fixed frame 21, the outer wall of the magnetic connector 20 is fixedly connected to the fixed frame 21 by an elastic rope, the interior of the fixed frame 21 is fixedly connected with a third spring 22, the front end of the third spring 22 is fixedly connected with a pushing plate 23, the front end of the pushing plate 23 is symmetrically fixedly connected with an extrusion cone plate 24, the extrusion cone plate 24 is arranged in an inclined surface, the side of the fixed frame 21 away from the magnetic connector 20 is fixedly connected with a counterweight block 26, the bottom of the fixed frame 21 is fixedly connected with a plug-in base 25, and an arc-shaped spring piece is arranged at the middle position of the plug-in base 25.
[0040] In this embodiment, although the connection between the magnetic joint 20 and the lightning arrester increases the stability of the connection, it is not suitable for leakage current testing in sudden severe weather. At this time, the staff has to climb to a high place to remove the magnetic joint 20, which increases the risk of the test. By setting an electromagnetic lock in the magnetic joint 20, the connection of the magnetic joint 20 can be disconnected in time in sudden severe weather. However, at this time, part of the magnetic joint 20 may still be connected to the lightning arrester. Specifically, the inclined surfaces on both sides of the extrusion conical plate 24 are set. When the magnetic joint 20 is connected to the lightning arrester, the push plate 23 is squeezed to make it The third spring 22 is in a contracted state. When the electromagnetic lock inside the magnetic connector 20 is disconnected, the force applied by the magnetic connector 20 to the push plate 23 is reduced. At this time, the third spring 22 is reset and pushes the push plate 23 and the extrusion conical plate 24 to move in the fixed frame 21, and pushes the magnetic connector 20 to completely disconnect from the lightning arrester. Therefore, the connection between the two can be disconnected in time as quickly as possible, thereby improving the safety of detection. It should be noted that the fixed frame 21 is connected to the base of the lightning arrester through the plug-in base 25, and the counterweight block 26 arranged on the side increases the stability of the installation of the fixed frame 21.
[0041] Example 2
[0042] like Figure 2 , Figure 3 and Figure 6As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, an arc-shaped protective ring 8 is fixedly connected to the inner wall of the first support seat 4 close to the conical protective cover 6, and a plurality of supporting spring plates 9 are fixedly connected to the inner wall of the arc-shaped protective ring 8. The arc-shaped protective ring 8 and the supporting spring plates 9 are elastically arranged, and a fixing rod 17 is fixedly connected to one side of the connecting line 5 close to the magnetic suction joint 20. The fixing rod 17 is elliptical in shape, and a second spring 18 is fixedly connected to the outer wall of the fixing rod 17. A supporting round rod 19 is fixedly connected to the outer wall of the second spring 18, and a through hole is opened on the outer wall of the supporting round rod 19.
[0043] Since the arrester leakage current test is mostly carried out at high altitude, the connecting wire 5 will inevitably shake, affecting the safety of the test and the accuracy of the data. The shaking at high altitude will also cause the surface of the connecting wire 5 to wear and reduce its service life. Severe intermittent contact of the terminal blocks will cause local discharge and generate high-temperature arcs, which may burn the surface of the arrester or ignite surrounding combustibles.
[0044] In this embodiment, an arc-shaped protective ring 8 and a supporting spring sheet 9 are arranged inside the first supporting seat 4 to reduce the wear of the connecting line 5 caused by swinging. A fixing rod 17, a second spring 18 and a supporting round rod 19 are arranged on the outer wall of the connecting line 5 fixed at a high altitude. It should be noted that a through hole is opened on the surface of the supporting round rod 19. When it is in the air and exposed to wind, the wind passes through the through holes on the surface of the supporting round rod 19. Since the fixing rod 17 is elliptical, the wind passes through the flat sides of the fixing rod 17, which reduces the influence of wind on the connecting line 5 and reduces the shaking of the connecting line 5. At the same time, under the action of the second spring 18, the impact of wind on the connecting line 5 is buffered, thereby improving the stability of the connecting line 5 during the test, and further improving the safety of the test and the accuracy of the data.
[0045] Example 3
[0046] like Figure 1 , Figure 4 and Figure 5 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the outer wall of the supporting round rod 19 is provided with a hollow rod 10, one end of the hollow rod 10 is fixedly connected with a buffer pad 11, the hollow rod 10 and the supporting round rod 19 are slidably connected, both sides of the buffer pad 11 are fixedly connected with an isolation cover 3, the buffer pad 11 is elastically arranged, and a weakening groove is provided on the surface of the buffer pad 11, the inner wall of the isolation cover 3 is slidably connected with a fixed plate 12, the inner wall of the fixed plate 12 is fixedly connected with a cleaning cotton 13, a plurality of nozzles 16 are fixedly connected to the inner side wall of the cleaning cotton 13, a plurality of limiting slide grooves 14 are provided on the inner side wall of the isolation cover 3, a first spring 15 is fixedly connected to the inner wall of the plurality of limiting slide grooves 14, and the first spring 15 is fixedly connected to the outer wall of the fixed plate 12.
[0047] Since the lightning arrester is located at high altitude, there are impurities such as oil and dust on its surface. Direct leakage current test will cause the current to be artificially high, making the test result inaccurate.
[0048] In this embodiment, the opening of the isolation cover 3 is set in an outwardly flipped arc shape. The opening can be aligned with the lightning arrester and pressed to directly fix it on the outside of the lightning arrester. The staff can rotate the isolation cover 3 to allow the internal cleaning cotton 13 to clean the surface of the lightning arrester. It should be noted that the inner wall of the cleaning cotton 13 is provided with a nozzle 16, which can spray anhydrous alcohol on the surface of the lightning arrester to prevent the surface leakage current from interfering with the test results.
[0049] The supporting round rod 19 is located on the inner wall of the hollow rod 10. The hollow rod 10 is connected to the isolation cover 3 through a buffer pad 11. During the test, the buffer pad 11 absorbs the impact of wind force again, further improving the safety of the test and the accuracy of the data.
[0050] The working principle of the auxiliary component based on the arrester leakage current test is explained in detail below.
[0051] like Figure 1-Figure 8As shown, when in use, the connecting line 5 is first connected to the detection body 1, the voltage multiplier 2 and the lightning arrester. When the test is started, the magnetic suction joint 20 is connected to the lightning arrester to increase the stability of the connection. In case of sudden severe weather, the connection of the magnetic suction joint 20 can be disconnected in time. The inclined surfaces on both sides of the extrusion cone plate 24 are arranged. When the magnetic suction joint 20 is connected to the lightning arrester, the pushing plate 23 is squeezed to make the third spring 22 behind it contracted. When the electromagnetic lock inside the magnetic suction joint 20 is disconnected, the force applied by the magnetic suction joint 20 to the pushing plate 23 is reduced. At this time, the third spring 22 is reset and pushes the pushing plate 23 and the extrusion cone plate 24 to move in the fixed frame 21, and pushes the magnetic suction joint 20 to completely disconnect from the lightning arrester, so that the connection between the two can be disconnected in time as soon as possible. The conical protective cover 6 and the arc baffle 7 at both ends of the first support seat 4 are arranged in an arc shape, which restricts the swinging and floating of the connecting line 5 while protecting the surface of the connecting line 5, so as to avoid the friction between the connecting line 5 and the first support seat 4 caused by the wind blowing, causing the connecting line 5 is damaged, a through hole is opened on the surface of the supporting round rod 19, when it is in the air and is blown by the wind, the wind passes through the through holes on the surface of the supporting round rod 19, and because the fixing rod 17 is set in an elliptical shape, the wind passes through the flat sides of the fixing rod 17, reducing the influence of wind on the connecting line 5 and reducing the shaking of the connecting line 5. At the same time, under the action of the second spring 18, the impact of wind on the connecting line 5 is buffered, and the opening of the isolation cover 3 is set in an arc shape that is turned outward. The opening can be aligned with the lightning arrester and pressed to directly fix it on the outside of the lightning arrester. The staff rotates the isolation cover 3 to allow the internal cleaning cotton 13 to clean the surface of the lightning arrester. It should be noted that the inner wall of the cleaning cotton 13 is provided with a nozzle 16, which can spray anhydrous alcohol on the surface of the lightning arrester to avoid surface leakage current interfering with the test results. The supporting round rod 19 is located on the inner wall of the hollow rod 10, and the hollow rod 10 is connected to the isolation cover 3 through a buffer pad 11. During the test, the buffer pad 11 is relied on to absorb the impact of wind again, further improving the safety of the test and the accuracy of the data.
[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
