Description

Technical Field

[0001] This utility model relates to the field of test rack technology, specifically to a thyristor switching switch rotating aging test rack. Background Technology

[0002] Thyristor switching devices are a new type of electrical equipment that can control the on / off state of circuits under high current and high voltage loads. They can effectively protect power equipment and systems and improve the reliability and stability of power systems, and are therefore widely used. In order to test whether the thyristor switching is working properly over a long period of time, the thyristor switching devices need to be placed on the corresponding test rack and connected to the power supply in sequence, so as to facilitate the testing of multiple thyristor switching devices.

[0003] A search revealed an existing patent (publication number: CN212646858U) that discloses an aging test rack, including a support device, a mounting plate, a fixing device, and a testing instrument. The support device has a structure that is narrower at the top and wider at the bottom, and it has several through holes. The top of the support device has a stepped structure, and the mounting plate is located on top of the stepped structure of the support device. The mounting plate is fixedly connected to the support device. The fixing device is located on top of the support device and is fixedly connected to the support device. The bottom of the fixing device has a through hole, and the testing instrument is located on top of the mounting plate. The testing instrument is fixedly connected to the mounting plate by bolts. This utility model allows electronic products to be pulled out of the aging test rack without the need for operators to reach into the aging test rack to remove the electronic products, effectively reducing the time required to remove the electronic products. The mounting plate is designed as a frame and mesh structure, which makes the testing of electronic products in the aging test rack more accurate and improves the testing accuracy of electronic products.

[0004] However, existing aging test racks are not convenient for ventilation and heat dissipation. When testing thyristor switching switches, the switches are usually operating under high load for a long time, which causes heat to accumulate faster. Moreover, multi-station operation will further cause the heat to accumulate too quickly. Excessive heat will affect the normal testing operation of the thyristor switching switches and may even damage the equipment in severe cases.

[0005] In view of this, the present invention proposes a thyristor switching switch rotating aging test frame. Utility Model Content

[0006] This invention proposes a thyristor switching switch rotating aging test frame, which solves the problem of inconvenient ventilation and heat dissipation in related technologies.

[0007] The technical solution of this utility model is as follows: a thyristor switching switch wheel-driven aging test rack, including a test rack body; universal wheels set at the bottom of the test rack body; anti-slip components symmetrically assembled at the lower ends of both sides of the test rack body, the anti-slip components being used to further improve the anti-slip stability of the test rack body; a controller fixedly connected to the upper end of one side of the test rack body; partitions fixedly connected at equal intervals to the inner wall of the test rack body; and a ventilation component assembled on the test rack body, the ventilation component being used for ventilation and heat dissipation during the thyristor switching switch test.

[0008] The ventilation assembly includes: an air outlet pipe fixedly connected to one end of the top of the partition; a blower hood fixedly connected to one side of the test frame body, one end of the blower hood being connected to one side of the back of the air outlet pipe via a conduit; a cooling fan fixedly connected to the inner wall of the blower hood; and a slot formed on one side of the blower hood, a dustproof net being engaged on one side of the blower hood, and a locking block being fixedly connected to one side of the dustproof net.

[0009] Preferably, the card block and the inside of the card slot form an engaging structure, and the card block protrudes from the outside of the card slot.

[0010] Preferably, a fixing structure is provided on one side of the blower hood. The fixing structure facilitates the quick assembly and disassembly of the dustproof net from the blower hood. The fixing structure includes: a fixing groove formed at the upper end of one side of the blower hood, with a vertical rod fixedly connected to the inner wall of the fixing groove; a toggle plate slidably connected to the surface of the vertical rod, with a fixing spring wound around the surface of the vertical rod, and the two ends of the fixing spring being fixedly connected to the top of the toggle plate and the inner top wall of the fixing groove, respectively; a positioning rod fixedly connected to one side of the bottom end of the toggle plate; and a positioning hole formed at the top of the locking block.

[0011] Preferably, the bottom end of the positioning rod and the interior of the positioning hole form an engaging structure, and the positioning rod is cylindrical in shape.

[0012] Preferably, the anti-slip component includes: a fixed box symmetrically fixedly connected to the lower ends of both sides of the test frame body, a threaded rod rotatably connected to the middle position of the inner wall of the fixed box, and a threaded plate threadedly connected to the surface of the threaded rod; a sliding rod fixedly connected at equal intervals to the bottom end of the threaded plate, the bottom end of the sliding rod extending to the outside of the fixed box and fixedly connected to an anti-slip plate; and a damping rotating handle rotatably connected to the middle position of the top of the fixed box, the bottom end of the rotating handle being fixedly connected to the top end of the threaded rod.

[0014] Preferably, the bottom of the anti-slip plate is provided with anti-slip patterns at equal intervals, and the anti-slip patterns are arc-shaped.

[0015] Preferably, an insulating pad is fixedly connected to the top of the partition, and the top of the insulating pad is provided with through holes at equal intervals.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, by starting the cooling fan, fresh air from outside is drawn into the blower hood after being filtered through the dustproof net, and then transported to the air outlet pipe through the duct. The air is then blown through the through groove on the front of the air outlet pipe towards the thyristor switching switch at the top of the partition, thereby achieving ventilation and heat dissipation. This avoids the rapid rise in temperature during the testing of multiple thyristor switching switches, reduces the impact of temperature on the test or the possibility of equipment damage, and ensures the accuracy of the test. At the same time, the dustproof net can be quickly disassembled and replaced, and it is convenient to clean and prevent clogging after the dustproof net is removed.

[0018] 2. In this utility model, the universal wheels make the test frame body easy and convenient to move. After being moved to the designated position, the universal wheels are locked by the braking mechanism. Then, by rotating the handle, the threaded rod is rotated, causing the threaded plate to slide down and the slide rod to slide down, so that the bottom of the anti-slip plate is in close contact with the ground. The arc-shaped anti-slip texture improves the anti-slip performance between the anti-slip plate and the ground, thereby improving the stability of the test frame body and preventing accidental sliding of the test frame body under force, which facilitates the stable testing of the thyristor switching device.

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] A preferred embodiment of the thyristor switching aging test fixture provided by this utility model is, for example... Figures 1 to 5 As shown: The thyristor switching switch rotation aging test rack includes a test rack body 7; casters 4 located at the bottom of the test rack body 7; anti-slip components 3 symmetrically mounted on the lower ends of both sides of the test rack body 7, the anti-slip components 3 being used to further improve the anti-slip stability of the test rack body 7; a controller 1 fixedly connected to the upper end of one side of the test rack body 7; partitions 6 fixedly connected at equal intervals to the inner wall of the test rack body 7; and a ventilation component 5 mounted on the test rack body 7, the ventilation component 5 being used for ventilation and heat dissipation during the thyristor switching switch test.

[0029] The ventilation assembly 5 includes: an air outlet duct 501 fixedly connected to one end of the top of the partition 6; a blower hood 503 fixedly connected to one side of the test frame body 7, one end of the blower hood 503 being connected to one side of the back of the air outlet duct 501 via a conduit; a cooling fan 504 fixedly connected to the inner wall of the blower hood 503; a slot 507 opened on one side of the blower hood 503, a dustproof net 502 being engaged on one side of the blower hood 503, and a locking block 506 fixedly connected to one side of the dustproof net 502.

[0030] In this embodiment, by activating the cooling fan 504, fresh air from outside is filtered through the dustproof net 502 and drawn into the blower hood 503. It is then transported to the air outlet 501 through the duct and blown by the through slot on the front of the air outlet 501 towards the thyristor switching switch at the top of the partition 6, thereby achieving ventilation and heat dissipation.

[0031] In a further preferred embodiment of the present invention, the card block 506 and the inside of the card slot 507 form an engaging structure, and the card block 506 protrudes from the outside of the card slot 507.

[0032] In this embodiment, the engagement between the card block 506 and the card slot 507 improves the stability of the initial engagement and installation of the dustproof net 502 and the blower hood 503.

[0033] In a further preferred embodiment of this utility model, a fixing structure is provided on one side of the blower hood 503. The fixing structure facilitates the quick assembly and disassembly of the dustproof net 502 and the blower hood 503. The fixing structure includes: a fixing groove 512 opened at the upper end of one side of the blower hood 503, and a vertical rod 511 fixedly connected to the inner wall of the fixing groove 512; a toggle plate 509 slidably connected to the surface of the vertical rod 511, and a fixing spring 510 wound around the surface of the vertical rod 511. The two ends of the fixing spring 510 are fixedly connected to the top end of the toggle plate 509 and the inner top wall of the fixing groove 512, respectively; a positioning rod 508 fixedly connected to one side of the bottom end of the toggle plate 509; and a positioning hole 505 opened at the top of the locking block 506.

[0034] In this embodiment, the dustproof net 502 and the locking block 506 are engaged with the blower hood 503 and the slot 507 respectively. Then, the elastic force of the fixed spring 510 is used to make the actuating plate 509 slide and drive the positioning rod 508 to lock into or disengage from the positioning hole 505, thereby realizing the quick installation and removal of the dustproof net 502.

[0035] In a further preferred embodiment of the present invention, the bottom end of the positioning rod 508 and the interior of the positioning hole 505 form an engaging structure, and the positioning rod 508 is cylindrical in shape.

[0036] In this embodiment, the engagement between the positioning rod 508 and the positioning hole 505 ensures the secure and stable engagement between the locking block 506 and the slot 507.

[0037] Example 2

[0038] Based on Example 1, a preferred embodiment of the thyristor switching switch rotating aging test fixture provided by this utility model is, for example... Figures 1 to 5 As shown: The anti-slip component 3 includes: a fixed box 301 symmetrically fixedly connected to the lower ends of both sides of the test frame body 7, a threaded rod 303 rotatably connected to the middle position of the inner wall of the fixed box 301, and a threaded plate 309 threadedly connected to the surface of the threaded rod 303; a sliding rod 307 fixedly connected at equal intervals to the bottom end of the threaded plate 309, the bottom end of the sliding rod 307 extending to the outside of the fixed box 301 and fixedly connected to the anti-slip plate 306; and a damping rotating handle 302 fixedly connected to the middle position of the top of the fixed box 301, the bottom end of the rotating handle 302 being fixedly connected to the top end of the threaded rod 303.

[0039] In this embodiment, rotating the handle 302 drives the threaded rod 303 to rotate, causing the threaded plate 309 to slide down and the slide bar 307 to slide down, thereby making the bottom of the anti-slip plate 306 stick tightly to the ground, which can improve the stability of the test frame body 7 and facilitate the stable testing of the thyristor switching.

[0040] In a further preferred embodiment of the present invention, a groove 304 is provided on the inner wall of the fixed box 301, and sliders 308 that slide and cooperate with the inside of the groove 304 are fixedly connected to both sides of the threaded plate 309.

[0041] In this embodiment, the sliding of the slider 308 inside the groove 304 is used to improve the smoothness of the threaded plate 309 sliding up and down.

[0042] In a further preferred embodiment of the present invention, anti-slip textures 305 are provided at equal intervals at the bottom end of the anti-slip plate 306, and the anti-slip textures 305 are arc-shaped.

[0043] In this embodiment, the anti-slip texture 305 is used to improve the anti-slip performance of the anti-slip plate 306 in contact with the ground.

[0044] In a further preferred embodiment of this utility model, an insulating pad 2 is fixedly connected to the top of the partition 6, and through holes are equally spaced on the top of the insulating pad 2.

[0045] In this embodiment, the use of an insulating pad 2 with through holes improves the anti-slip properties of the thyristor switching switch placed on the surface of the insulating pad 2, and also enables the insulating pad 2 to be placed insulated from the partition 6.

[0046] The working principle of this utility model is as follows: First, the casters 4 make it easy to move the test frame body 7. After moving it to the designated position, the braking mechanism on the casters 4 is used to lock the casters 4. Then, by rotating the handle 302, the threaded rod 303 is rotated. The threaded engagement between the threaded rod 303 and the threaded plate 309 causes the threaded plate 309 to slide down, which in turn causes the slide rod 307 to slide down. This makes the bottom of the anti-slip plate 306 stick to the ground. The arc-shaped anti-slip texture 305 improves the anti-slip performance of the anti-slip plate 306 in contact with the ground, thereby improving the stability of the test frame body 7 and facilitating the subsequent stable testing of the thyristor switching device.

[0047] Then, the thyristor switching switches are placed on the surface of the insulating pad 2 at the top of the partition 6 in sequence, and then the external power supply is connected in sequence to carry out normal aging test. At the same time, during the test, the cooling fan 504 is turned on to draw fresh air from outside through the dust filter 502 into the blower hood 503, and then delivered to the air outlet 501 through the duct. The air outlet 501 blows the air onto the thyristor switching switches at the top of the partition 6 through the through groove on the front of the air outlet 501, thereby achieving ventilation and heat dissipation, avoiding rapid temperature rise during the test of multiple thyristor switching switches, and reducing the impact of temperature on the test or the possibility of equipment damage.

[0048] Furthermore, by periodically moving the actuating plate 509, it can slide on the surface of the vertical rod 511 and compress the fixing spring 510, while simultaneously driving the positioning rod 508 to rise until it is completely disengaged from the positioning hole 505. Then, the dustproof net 502 can be disassembled by the locking block 506, which facilitates the cleaning and anti-clogging of the dustproof net 502. During installation, first move the actuating plate 509 to drive the positioning rod 508 to rise, then lock the dustproof net 502 and the locking block 506 into the blower hood 503 and the slot 507, then release the actuating plate 509. Using the elasticity of the fixing spring 510, the actuating plate 509 slides down, driving the positioning rod 508 into the positioning hole 505, thus achieving quick installation and removal of the dustproof net 502.

[0049] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
