Description

Technical Field

[0001] The invention belongs to the technical field of lightning arrester testing, and in particular is a lightning arrester live testing device and a testing method thereof. Background Art

[0002] A lightning arrester is an electrical appliance used to protect electrical equipment from high transient overvoltages and to limit the follow-on time and follow-on amplitude. A lightning arrester is an important and indispensable device for the power system. If the power grid is attacked by atmospheric overvoltage or internal overvoltage, the lightning arrester will instantly act to conduct to the ground, and the insulation will be restored after releasing the overvoltage energy, thereby protecting the power grid from overvoltage damage. It is necessary to inspect the lightning arrester regularly to ensure its effectiveness.

[0003] For example, a Chinese patent with application number 2022105058272 discloses a lightning arrester live test device and test method, which include: a base and a detector fixed on the base, a visual sensor is fixed on the detector, a fixed plate is also fixed on the base, and a plurality of groups of symmetrically arranged wheels are rotatably mounted on the base; a driving mechanism is provided on the fixed plate, and a lifting mechanism connected to the driving mechanism is provided on the base. However, if the wind force is too strong, the test line will be twisted, and in severe cases, the test line will be bent, affecting the test effect.

[0004] Based on the above scheme, during the test process, the test line will shake under the action of wind, causing the connection between the wiring clip and the lightning arrester terminal to loosen, resulting in poor contact; if the wind is too strong, the test line will be twisted, and in severe cases, the test line will be bent, affecting the test effect; when there is poor contact between the wiring clip and the lightning arrester connection, the resistance becomes larger, causing the temperature of the wiring clip and the test line to rise.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 10 As shown, a lightning arrester live testing device of the present invention comprises a testing component 1, a limiting component 2 is arranged on one side of the testing component 1, and a protection component 3 is arranged above the testing component 1.

[0042] like Figure 2 As shown, the test component 1 includes a tester body 103 and a test line 105, one end of the test line 105 is provided with a wiring plug 106, and the end of the test line 105 away from the wiring plug 106 is provided with a wiring clip 107, the surface of the tester body 103 is provided with a test socket adapted to the wiring plug 106, the test line 105 is connected to the tester body 103 through the wiring plug 106, and the end of the wiring clip 107 away from the test line 105 is provided with a lightning arrester terminal.

[0043] A placing table 102 is arranged below the tester body 103, a mobile body 101 is arranged below the placing table 102, a storage box 104 is arranged on one side of the placing table 102 for storing the test line 105, a through hole is opened on the surface of the storage box 104 for the test line 105 to enter and exit, an electric telescopic rod 108 is arranged above the mobile body 101, an insulating bracket 109 is arranged above the electric telescopic rod 108, a fixing frame 201 is arranged on the insulating bracket 109, and a fixing groove is opened at the position where the fixing frame 201 is connected to the insulating bracket 109.

[0044] like Figures 3 to 5 As shown, the limit assembly 2 includes a fixed frame 201, a fixed seat 202 is arranged above the fixed frame 201, a hydraulic rod 203 is arranged on the surface of the fixed seat 202, a limit seat 204 is arranged at one end of the hydraulic rod 203 away from the fixed seat 202, a compression spring 205 is arranged at one end of the limit seat 204 away from the hydraulic rod 203, a limit clamping plate 206 is arranged at one end of the compression spring 205 away from the limit seat 204, limit sliding columns 208 are arranged at both ends of the limit clamping plate 206, a limit sliding seat 207 is arranged at one end of the limit sliding column 208 away from the limit clamping plate 206, and one end of the limit sliding seat 207 away from the limit sliding column 208 is connected to the limit seat 204.

[0045] There are four limit clamps 206 , and the four limit clamps 206 are arranged in a ring shape on the surface of the test line 105 . The surface of the limit clamp 206 is provided with an arc groove matched with the test line 105 .

[0046] When in use, the controller controls the four hydraulic rods 203 to extend respectively, and the hydraulic rods 203 drive the limit seat 204, the compression spring 205 and the limit clamp 206 to move in the direction close to the test line 105, so that the four limit clamps 206 clamp and limit the test line 105. During this process, the compression spring 205 is compressed, and the limit slide 208 moves inside the limit slide 207, and the length of the limit slide 208 extending out of the limit slide 207 is reduced. By setting the limit slide 208, the limit slide 207 and the compression spring 205 to cooperate, the test line 105 is elastically clamped.

[0047] When in use, first use the mobile body 101 to move the tester body 103 to the test position according to the lightning arrester, so as to flexibly move the tester body 103 according to the test position, and then connect the tester body 103 to the lightning arrester to be tested through the test line 105. At this time, the end of the test line 105 with the wiring plug 106 is inserted into the test socket on the tester body 103, and then according to the wiring height of the lightning arrester, the controller controls the electric telescopic rod 108 to extend, and the electric telescopic rod 108 drives the insulating bracket 109 and the limit assembly 2 to move together. In this process, the end of the test line 105 with the wiring clip 107 is raised together with the electric telescopic rod 108, and then the wiring clip 107 is installed at the lightning arrester wiring terminal. After the wiring is completed, check whether the line is connected again, and then turn on the power switch to perform a live test on the lightning arrester through the tester body 103.

[0048] During the test, the test line 105 may be shaken by the wind, causing the connection between the wiring clip 107 and the lightning arrester terminal to loosen, resulting in poor contact. If the wind is too strong, the test line 105 may be twisted, and in severe cases, the test line 105 may be bent, affecting the test effect. When there is poor contact between the wiring clip 107 and the lightning arrester connection, the resistance increases, causing the temperature of the wiring clip 107 and the test line 105 to rise. If the temperature is too high, it will affect the safety of use.

[0049] In order to solve the above problems, the testing device also includes:

[0050] like Figures 6 to 9As shown, the protection component 3 includes a protection sleeve 301, a support frame 304 is arranged inside the protection sleeve 301, an elastic airbag 305 is arranged on the support frame 304, an air hose 307 is arranged at one end of the elastic airbag 305, an adjusting airbag 306 is arranged at the end of the air hose 307 away from the elastic airbag 305, a small air pump is equipped on the air hose 307, an air nozzle 308 is arranged at the end of the elastic airbag 305 away from the air hose 307, a connecting strip 309 is arranged at the end of the elastic airbag 305 away from the test line 105, a ventilation plate 310 is arranged at the end of the connecting strip 309 away from the elastic airbag 305, a ventilation groove 303 is opened on the surface of the protection sleeve 301, the ventilation groove 303 is adapted to the ventilation plate 310, a plurality of heat sinks 302 are arranged on the protection sleeve 301, a plurality of heat dissipation holes are opened on the surface of the heat sink 302, and the heat dissipation of the test line 105 is dissipated by setting the heat sink 302.

[0051] There are four elastic airbags 305 , which are arranged in a ring shape on the surface of the test line 105 . There are four regulating airbags 306 , which are arranged in a ring shape on the surface of the test line 105 .

[0052] like Figure 3 As shown, the test line 105 passes through and extends to the outside of the protective component 3, the protective component 3 is arranged at one end of the test line 105 close to the wiring clip 107, the air nozzle 308 passes through and extends to the outside of the protective cover 301, and the air nozzle 308 is located on the side close to the wiring clip 107.

[0053] When in use, the protective component 3 is used to limit the end of the test line 105 close to the wiring clip 107, and the elastic airbag 305 and the regulating airbag 306 are used to elastically support the end of the test line 105 close to the wiring clip 107 to prevent the test line 105 from being twisted off at the connection between the wiring clip 107 when it is windy. In addition, the controller controls the small air pump to transport the gas in the elastic airbag 305 to the regulating airbag 306 through the air hose 307, thereby increasing the expansion amount of the regulating airbag 306, thereby changing the pressure of the regulating airbag 306 on the test line 105.

[0054] like Figure 6 As shown, a mounting frame 311 is provided on the surface of the protective cover 301, and the protective cover 301 is supported by the mounting frame 311. A support platform 312 is provided below the mounting frame 311, and one end of the insulating bracket 109 away from the electric telescopic rod 108 is connected to the support platform 312, and both ends of the support platform 312 are provided with limiting card plates 313, and one end of the mounting frame 311 close to the limiting card plate 313 is provided with a protrusion, and a card groove matched with the protrusion is opened on the surface of the limiting card plate 313, and the protrusion and the card groove are matched, so that the limiting card plate 313 limits the mounting frame 311.

[0055] A pressure sensor is provided inside the limiting clamp 206. When the limiting clamp 206 is squeezed by the test line 105, the pressure sensor detects the pressure exerted by the test line 105 on the limiting clamp 206, thereby determining the degree of deviation of the test line 105 under the action of wind.

[0056] During the test, the test line 105 may be shaken by the wind, so that the test line 105 may press the limit clamp 206. Fig.10 ), specifically:

[0057] When the test line 105 deviates to the left, the test line 105 squeezes the limit clamp 206 on the left side, and the compression spring 205 is deformed. During this process, the limit clamp 206 drives the limit slide 208 to move in the direction close to the compression spring 205. At this time, the length of the limit slide 208 extending out of the limit slide seat 207 is reduced. Under the squeezing action of the limit clamp 206, the compression spring 205 is compressed and deformed. The greater the compression of the compression spring 205, the greater the squeezing force of the test line 105 on the limit clamp 206, and the greater the detection value of the pressure sensor on the limit clamp 206.

[0058] When the detection value of the pressure sensor exceeds the preset value, it indicates that the distortion degree of the test line 105 increases. The controller controls the hydraulic rod 203 on the left to extend. The hydraulic rod 203 drives the limit seat 204, the compression spring 205 and the limit clamp 206 to move in the direction close to the test line 105. At this time, the limit clamp 206 applies a thrust to the test line 105. At this time, the thrust direction is opposite to the offset direction of the test line 105, thereby reducing the distortion degree of the bent part of the test line 105, avoiding excessive distortion of the test line 105, causing the test line 105 to bend, and affecting the test effect.

[0059] When the test line 105 deviates to the right, the test line 105 squeezes the limit clamp 206 on the right side, and the compression spring 205 is deformed. In this process, the limit clamp 206 drives the limit slide 208 to move in the direction close to the compression spring 205. At this time, the length of the limit slide 208 extending out of the limit slide seat 207 is reduced. Under the squeezing action of the limit clamp 206, the compression spring 205 is compressed and deformed. When the detection value of the pressure sensor exceeds the preset value, it indicates that the test line 105 moves in the direction away from the wiring clip 107. The controller controls the hydraulic rod 203 on the right to extend, and the hydraulic rod 203 drives the limit seat 204, the compression spring 205 and the limit clamp 206 to move together in the direction close to the test line 105. At this time, the limit clamp 206 applies a thrust to the test line 105 to prevent the test line 105 from pulling the wiring clip 107 to loosen or fall off, affecting the test effect.

[0060] At the same time, the controller controls the small air pump to transport the gas in the elastic airbag 305 to the regulating airbag 306 through the air hose 307, thereby increasing the expansion volume of the four regulating airbags 306, so that the regulating airbags 306 squeeze and fix the test line 105 to prevent the test line 105 in the protective cover 301 from moving.

[0061] If the test line 105 shakes back and forth (see Fig.10 ), for example, specifically:

[0062] When the test line 105 deviates backward, the test line 105 squeezes the limit clamp 206 on the rear side, and the compression spring 205 is deformed. During this process, the limit clamp 206 drives the limit slide 208 to move in the direction close to the compression spring 205. At this time, the length of the limit slide 208 extending out of the limit slide 207 is reduced. Under the squeezing action of the limit clamp 206, the compression spring 205 is compressed and deformed. The greater the compression of the compression spring 205, the greater the squeezing force of the test line 105 on the limit clamp 206, and the greater the detection value of the pressure sensor on the limit clamp 206.

[0063] When the detection value of the pressure sensor exceeds the preset value, it indicates that the distortion degree of the test line 105 increases. The controller controls the hydraulic rod 203 on the rear side to extend. The hydraulic rod 203 drives the limit seat 204, the compression spring 205 and the limit clamp 206 to move in the direction close to the test line 105. At this time, the limit clamp 206 applies a thrust to the test line 105. At this time, the thrust direction is opposite to the offset direction of the test line 105, thereby reducing the distortion degree of the bent part of the test line 105, avoiding excessive distortion of the test line 105, causing the test line 105 to bend, and affecting the test effect.

[0064] In this process, since the test line 105 squeezes the regulating airbag 306 on the rear side, the controller controls the small air pump to transport the gas in the elastic airbag 305 on the rear side to the regulating airbag 306 through the air hose 307, thereby increasing the expansion amount of the regulating airbag 306 on the rear side, and increasing the squeezing force of the regulating airbag 306 on the test line 105, thereby correcting the test line 105 and reducing the degree of distortion of the test line 105.

[0065] When there is a poor contact between the wiring clip 107 and the arrester connection, the resistance increases, causing the temperature of the wiring clip 107 and the test line 105 to rise. At this time, the elastic airbag 305 and the regulating airbag 306 expand due to the heat. The temperature of the end of the test line 105 close to the wiring clip 107 is determined by detecting the deformation of the elastic airbag 305. The larger the deformation of the elastic airbag 305, the higher the temperature of the test line 105. Specifically:

[0066] When the deformation of the elastic airbag 305 is at the first threshold, the elastic airbag 305 expands and the regulating airbag 306 expands and contacts the heat sink 302, thereby transferring the heat of the test line 105 to the heat sink 302 through the elastic airbag 305 and the regulating airbag 306, increasing its heat dissipation area and reducing the temperature at the wiring clip 107 and the test line 105.

[0067] In the above process, since the elastic airbag 305 expands due to heat and becomes larger in volume, the elastic airbag 305 squeezes the connecting strip 309, and the connecting strip 309 drives the ventilation plate 310 to move away from the test line 105, so that the ventilation plate 310 extends out of the ventilation groove 303 on the surface of the protective cover 301, so that the outside air enters the interior of the protective cover 301, allowing the air to circulate and enhancing the heat dissipation effect.

[0068] When the deformation of the elastic airbag 305 exceeds the first threshold, the controller opens the valve so that the gas inside the four elastic airbags 305 is sprayed toward the wiring clamp 107 through the air nozzle 308, accelerating the air flow around the wiring clamp 107, thereby achieving jet cooling.

[0069] When the deformation of the elastic airbag 305 exceeds the second threshold, in order to avoid danger caused by excessive temperature, the controller first controls the hydraulic rods 203 at the front and rear ends of the fixing frame 201 to contract (see for details). Fig.10), thereby separating the limit clamps 206 at the front and rear ends from the test line 105, and then controlling the left hydraulic rod 203 to extend through the controller, so that the left hydraulic rod 203 drives the limit seat 204, the compression spring 205 and the limit clamp 206 to push the test line 105 in the direction away from the wiring clip 107. At the same time, the controller controls the right hydraulic rod 203 to contract, so that the right hydraulic rod 203 drives the limit seat 204, the compression spring 205 and the limit clamp 206 to move in the direction away from the wiring clip 107. Under the joint action of the left and right hydraulic rods 203, the test line 105 is pulled and the wiring clip 107 is separated from the arrester wiring terminal, thereby disconnecting the protection thereof.

[0070] It is worth noting that; in this process, the adjustment airbag 306 is expanded and squeezed to fix the test line 105 at that location, so that the test line 105 drives the support frame 304, the protective cover 301 and the mounting frame 311 to move in the direction away from the wiring clip 107. At this time, the protrusion on the mounting frame 311 is disengaged from the slot on the limiting card plate 313, so that the mounting frame 311 moves on the support platform 312.

[0071] A testing method for a lightning arrester live testing device, the specific testing method steps are as follows:

[0072] S1: First, move the test assembly 1 to a designated test position, and then connect the tester body 103 to the circuit as required;

[0073] S2: Secondly, when connecting the line, connect the end of the test line 105 with the wiring plug 106 to the tester body 103, and connect the end of the test line 105 with the wiring clip 107 to the arrester wiring terminal;

[0074] S3: Then the test line 105 is limited by the limit component 2 to prevent the test line 105 from shaking under the action of wind and affecting the accuracy of the test result;

[0075] S4: After the wiring is finally completed, check again whether the line is connected, turn on the power switch, and use the tester body 103 to perform the test.

[0076] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
