Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a reliability testing device for a lightning protection device. Background Art

[0002] A surge protector, also known as a lightning arrester, is a device used to protect electrical equipment from voltage surges or overvoltage damage. In the power system, voltage surges or overvoltages may occur due to lightning strikes, switch operations, power load changes, etc., which may cause damage or failure to the equipment. The function of a surge protector is to protect electrical equipment from being affected by absorbing, dispersing or suppressing these overvoltages.

[0003] Surge protectors must undergo various tests during the production process. Among them, reliability testing in various environments is also crucial, including the working conditions of the lightning protector under external pressure, external shock and vibration environments. Reliability testing can ensure that the surge protector meets the requirements of specific usage environments.

[0004] However, in the existing technology, during the testing process of surge protectors, a single device often cannot meet the reliability testing requirements under multiple complex environmental factors such as impact, extrusion and vibration. This is mainly because the impact mechanisms and testing requirements of various environmental factors on surge protectors are different, and special equipment is required for precise measurement and simulation. Specifically, the impact test needs to simulate the performance of the device when it is subjected to sudden external force impact to evaluate its impact resistance; the extrusion test needs to simulate the performance changes of the device when it is under pressure to test its structural strength and stability; and the vibration test focuses on the operation of the device in a continuous vibration environment to ensure its stability and reliability under different vibration frequencies and amplitudes. In addition, different equipment needs to be used to perform various tests during the test process, which not only increases the operational complexity and time cost of the test process, but also greatly increases the test cost, which is not conducive to practical applications. Utility Model Content

[0005] The utility model aims to provide a reliability testing device for a lightning protection device to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A reliability test device for a lightning protection device comprises a main body; a first servo module is installed on the top of the main body, a movable end of the first servo module is fixedly connected to a movable platform plate, a yielding component is provided on the top of the movable platform plate, an operating platform plate is provided on the top of the yielding component, a clamping component is provided on the operating platform plate, and the clamping component is used to fix a lightning arrester to be tested; a mounting frame is fixedly connected to the top of the main body, a second servo module is installed on the top of the mounting frame, a movable end of the second servo module is fixedly connected to a mounting plate, a pressure generating component is provided on the mounting plate, and the pressure generating component is used to act on the lightning arrester; a switching component is also provided at the bottom of the mounting plate, and the switching component is used to switch the action mode of the pressure generating component; a supporting component is also provided on the top of the main body, and the supporting component is used to cooperate with the yielding component to provide rigid support when the pressure generating component acts; a multimeter is fixedly installed on the top of the operating platform plate.

[0008] By adopting the above technical solution, a switching component is set up to cooperate with the pressure generating component to create different working environments. When performing pressure resistance test and impact resistance test, the switching component does not cooperate with the pressure generating component, so it only simulates the pressing and impact environment. When performing vibration resistance test, the switching component cooperates with the pressure generating component to generate a vibration environment, thereby realizing a comprehensive test of pressure, impact and vibration environment for a single device, which greatly facilitates practical applications and reduces the cost of testing.

[0009] A further improvement of the technical solution of the utility model is that the pressure generating component includes a hydraulic cylinder, the hydraulic cylinder is fixedly connected to the top of the mounting plate, and the piston rod of the hydraulic cylinder extends to the bottom of the mounting plate and is fixedly connected with a pressure block.

[0010] By adopting the above technical solution, it is convenient to push the pressing block downwards through the operation of the hydraulic cylinder, so that the pressing block can be movable and different working environments can be created.

[0011] A further improvement of the technical solution of the utility model is that the yielding component comprises a telescopic rod, a plurality of telescopic rods are fixedly connected between the movable platform plate and the operating platform plate, and springs are sleeved on the outer sides of the telescopic rods.

[0012] By adopting the above technical solution, when impacted or pressed, the operating platform plate will move downward, and then cooperate with the supporting components for support; and when vibrating, the vibration state can be expanded to improve the vibration effect.

[0013] A further improvement of the technical solution of the utility model is that the supporting component includes a supporting block fixedly connected to the top of the main body, a supporting beam is fixedly connected between the tops of the supporting blocks, a rib beam is fixedly connected to the bottom of the operating platform plate, and the rib beam and the supporting beam are perpendicular to each other.

[0014] By adopting the above technical solution, when the rib beam moves downward to contact with the support beam, the support beam can be used to support the rib beam.

[0015] A further improvement of the technical solution of the utility model is that the switching component includes an arc plate symmetrically fixedly connected to the top of the operating platform plate, the diameter of the inner wall of the arc plate is equal to the diameter of the outer side of the pressing block, and the inner wall of the arc plate and the outer side of the pressing block are both provided with rough surfaces.

[0016] By adopting the above technical scheme, the first servo module and the second servo module are controlled to work so that the pressing block contacts the inner wall of the curved plate in the horizontal direction. The test process is carried out by controlling the operation of the hydraulic cylinder to extend and retract. The process is repeated many times. Since the pressing block contacts one side of the rough surface of the curved plate, vibration will be generated during the up and down reciprocating motion of the pressing block.

[0017] A further improvement of the technical solution of the utility model is that the clamping component includes a control frame fixedly connected to the bottom of the operating platform plate, a two-way screw rod is rotatably connected between the inner walls of the control frame, one end of the two-way screw rod extends to the outside of the control frame and is fixedly connected to a turning handle, a slider is symmetrically threaded on the outside of the two-way screw rod, the slider is slidably connected to the inner wall of the control frame, a through groove is opened on the top of the operating platform plate, a chuck is fixedly connected to the top of the slider, and the chuck extends to the top of the operating platform plate through the through groove.

[0018] By adopting the above technical solution, the bidirectional screw rod is rotated by turning the handle, thereby causing the two sliders to move toward the adjacent side and driving the chuck to move toward the adjacent side to fix the lightning arrester.

[0019] A further improvement of the technical solution of the utility model is that: a guide rod is fixedly connected to the top of the pressing block, the top of the guide rod passes through to the top of the mounting plate, and the guide rod is slidably connected to the mounting plate.

[0020] By adopting the above technical solution and providing a guide rod, the activity trajectory of the pressing block can be corrected to improve stability.

[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 provides a reliability testing device for a lightning protection device. By setting a switching component, it can cooperate with a pressure generating component to create different working environments. When performing a pressure resistance test and an impact resistance test, the switching component does not cooperate with the pressure generating component, so it only simulates the pressing and impact environment. When performing a vibration resistance test, the switching component cooperates with the pressure generating component to generate a vibration environment, thereby achieving a comprehensive test of the pressure, impact and vibration environment for a single device, while reducing the cost of the test, which is beneficial to practical applications.

[0023] 2. The utility model provides a reliability testing device for a lightning protection device. By arranging a supporting component and a giving way component, during a pressing or impacting process, the operating platform plate will initially move downward, the telescopic rod will contract, and the spring will be squeezed until the rib beam contacts the top of the supporting beam.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] Example

[0034] like Figure 1-Figure 6As shown, the utility model provides a reliability testing device for a lightning protection device, comprising a main body 1; a first servo module 3 is installed on the top of the main body 1, and a movable end of the first servo module 3 is fixedly connected to a movable platform plate 6, a yielding component is provided on the top of the movable platform plate 6, and an operating platform plate 9 is provided on the top of the yielding component, and a clamping component is provided on the operating platform plate 9, and the clamping component is used to fix the lightning arrester to be tested; a mounting frame 2 is fixedly connected to the top of the main body 1, a second servo module 4 is installed on the top of the mounting frame 2, and a mounting plate 10 is fixedly connected to the movable end of the second servo module 4, and a pressure generating component is provided on the mounting plate 10, and the pressure generating component is used to act on the lightning arrester; a switching component is also provided at the bottom of the mounting plate 10, and the switching component is used to switch the action mode of the pressure generating component; a supporting component is also provided on the top of the main body 1, and the supporting component is used to cooperate with the yielding component to provide rigid support when the pressure generating component acts; a multimeter 18 is fixedly installed on the top of the operating platform plate 9.

[0035] In this embodiment, a switching component is provided to cooperate with the pressure generating component to create different working environments. When performing pressure resistance test and impact resistance test, the switching component does not cooperate with the pressure generating component, so it only simulates the pressing and impact environment. When performing vibration resistance test, the switching component cooperates with the pressure generating component to generate a vibration environment, thereby enabling a single device to complete comprehensive testing of pressure, impact and vibration environments, while reducing the cost of testing, which is beneficial to practical applications.

[0036] like Figure 1 and Figure 2 As shown, preferably, the pressure generating component includes a hydraulic cylinder 11, which is fixedly connected to the top of the mounting plate 10, and a piston rod of the hydraulic cylinder 11 extends to the bottom of the mounting plate 10 and is fixedly connected to a pressure block 12.

[0037] In this embodiment, the pressing block 12 is pushed downward by the hydraulic cylinder 11 so that the pressing block 12 can move and create different working environments.

[0038] like Figure 3 and Figure 4 As shown, preferably, the making way component includes a telescopic rod 7, a plurality of telescopic rods 7 are fixedly connected between the movable platform plate 6 and the operating platform plate 9, and springs 8 are sleeved on the outer sides of the telescopic rods 7.

[0039] In this embodiment, when impacted or pressed, the operating platform plate 9 will move downward to cooperate with the supporting components for support; and when vibrating, the spring 8 can expand the vibration state to improve the vibration effect.

[0040] like Figure 3 and Figure 4As shown, the support component includes a support block 16 fixedly connected to the top of the main body 1, a support beam 17 is fixedly connected between the tops of the support blocks 16, and a rib beam 24 is fixedly connected to the bottom of the operating platform plate 9, and the rib beam 24 and the support beam 17 are perpendicular to each other.

[0041] In this embodiment, when the rib beam 24 moves downward to contact the support beam 17 , the support beam 17 can be used to support the rib beam 24 .

[0042] like Figure 3 and Figure 4 As shown, preferably, the switching component includes an arc plate 14 symmetrically fixedly connected to the top of the operating platform plate 9, the diameter of the inner wall of the arc plate 14 is equal to the diameter of the outer side of the pressing block 12, and the inner wall of the arc plate 14 and the outer side of the pressing block 12 are both provided with a rough surface 15.

[0043] In this embodiment, the first servo module 3 and the second servo module 4 are controlled to work so that the pressure block 12 contacts the inner wall of the arc plate 14 in the horizontal direction. The test process is carried out by controlling the hydraulic cylinder 11 to extend and retract. The process is repeated many times. Since the pressure block 12 contacts the side of the arc plate 14 with the rough surface 15, vibration will be generated during the up and down reciprocating motion of the pressure block 12.

[0044] like Figure 4 As shown, preferably, the clamping component includes a control frame 5 fixedly connected to the bottom of the operating platform plate 9, a bidirectional screw rod 20 is rotatably connected between the inner walls of the control frame 5, one end of the bidirectional screw rod 20 extends to the outside of the control frame 5 and is fixedly connected to a turning handle 23, and a slider 21 is symmetrically threaded on the outer side of the bidirectional screw rod 20, and the slider 21 is slidably connected to the inner wall of the control frame 5, a through groove 19 is opened on the top of the operating platform plate 9, and a chuck 22 is fixedly connected to the top of the slider 21, and the chuck 22 extends to the top of the operating platform plate 9 through the through groove 19.

[0045] In this embodiment, the bidirectional screw rod 20 is rotated by rotating the turning handle 23, thereby causing the two sliders 21 to move toward the side close to each other, and driving the clamp 22 to move toward the side close to each other, so as to fix the lightning arrester.

[0046] like Figure 1 and Figure 2 As shown, preferably, a guide rod 13 is fixedly connected to the top of the pressing block 12 , and the top of the guide rod 13 passes through to the top of the mounting plate 10 , and the guide rod 13 is slidably connected to the mounting plate 10 .

[0047] During impact and pressure tests, the hydraulic cylinder 11 has a large potential energy, while during vibration tests, it will be affected by shaking and its stability will be affected.

[0048] In this embodiment, by providing the guide rod 13, the moving track of the pressing block 12 can be corrected to improve the stability.

[0049] The following is a detailed description of the working principle of the reliability testing device for the lightning protection device.

[0050] like Figure 1-Figure 6 As shown, the lightning arrester to be tested is placed on the operating platform plate 9, and the bidirectional screw rod 20 is rotated by turning the handle 23, thereby causing the two sliders 21 to move toward the side close to each other, and driving the clamp 22 to move toward the side close to each other, so as to fix the lightning arrester. After the lightning arrester is fixed, the detection head of the multimeter 18 can be connected to the interface of the lightning arrester. After adjusting the multimeter 18, the test under a specific environment can be started.

[0051] Pressure test: by controlling the first servo module 3 and the second servo module 4 to work, the area between the two clamps 22 is located directly below the pressure block 12, and the pressure block 12 will not contact the arc plate 14 in the horizontal direction; by controlling the hydraulic cylinder 11 to slowly extend, the pressure block 12 squeezes the lightning arrester, and observes the value change of the multimeter 18 during the pressure application process; during the pressing process, the operating platform plate 9 will initially move downward, the telescopic rod 7 will shrink, and the spring 8 will be squeezed until the rib beam 24 contacts the top of the support beam 17. At this time, the support beam 17 can support the rib beam 24, and then provide rigid support, while avoiding excessive pressure to cause damage to the first servo module 3. The pressure threshold for the sudden change in value can be used as an important parameter for pressure bearing capacity.

[0052] Impact resistance test: Under the same conditions as mentioned above, control the hydraulic cylinder 11 to extend at a relatively faster speed so that the pressure block 12 impacts the lightning arrester. During the impact process, the operating platform plate 9 will initially move downward, the telescopic rod 7 will contract, and the spring 8 will be squeezed until the rib beam 24 contacts the top of the support beam 17. At this time, the support beam 17 can support the rib beam 24, thereby providing rigid support, while avoiding damage to the first servo module 3 caused by excessive impact. At the same time, taking readings can test the impact resistance of the lightning arrester.

[0053] Vibration resistance test: control the first servo module 3 and the second servo module 4 to work, so that the pressure block 12 contacts with the inner wall of the arc plate 14 in the horizontal direction. The test process controls the hydraulic cylinder 11 to work, extend and retract, and the process is repeated many times. However, the pressure block 12 does not contact the lightning arrester and the operating platform plate 9 during the downward process. Since the pressure block 12 contacts with the side of the arc plate 14 with the rough surface 15, vibration will be generated during the up and down reciprocating motion of the pressure block 12. The vibration frequency can be controlled by the extension and retraction speed of the hydraulic cylinder 11 as needed. At this time, the reliability test of the lightning arrester under the vibration environment can be completed by observing the reading of the multimeter 18.

[0054] 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.
