Description

Technical Field

[0001] This invention relates to the field of frequency converter testing technology, specifically a novel ABB frequency converter testing platform. Background Technology

[0002] ABB frequency converters are a well-known brand of frequency converters developed, manufactured, and sold by the ABB Group. They are mainly used to control and regulate the speed of three-phase AC asynchronous motors. With their stable performance, rich combination functions, high-performance vector control technology, low-speed high torque output, good dynamic characteristics, and strong overload capacity, they occupy an important position in the frequency converter market. After production, they need to be tested.

[0003] The heat dissipation effect of existing high-voltage frequency converters has high requirements for the ambient air temperature and air cleanliness. However, whether high-voltage frequency converters can be used in high-temperature and high-dust environments is not convenient to test during commissioning, which affects the efficiency and effectiveness of testing.

[0004] Therefore, we propose a new ABB frequency converter testing platform. Summary of the Invention

[0009] Preferably, the telescopic mechanism includes two symmetrically arranged sleeves fixedly connected to the bottom of the lifting plate, and each sleeve is fitted with a sleeve rod. The lower end of the sleeve rod is fixed to the top of the heat insulation cover, and a first spring is fitted on the side wall of each sleeve.

[0010] Preferably, the moving mechanism includes a moving block fixedly sleeved on the side wall of the detection head, and a first reset mechanism is provided between the moving block and the heat insulation cover. An L-shaped frame is fixedly connected to the side wall of the lifting plate, and an inclined plate is fixedly connected to the bottom of the L-shaped frame.

[0011] Preferably, the first reset mechanism includes two symmetrically arranged first T-shaped guide rods inserted into the side wall of the moving block. The first T-shaped guide rods are fixed to the side wall of the heat insulation cover, and a second spring is sleeved on the side wall of each first T-shaped guide rod.

[0012] Preferably, the switching component includes a working cover fixedly inserted into the side wall of the sixth connecting pipe, and a sealing plate is connected inside the working cover through a second reset mechanism.

[0015] Preferably, the drive mechanism includes a driven bevel gear fixedly connected to the end of the rotating shaft, and a mounting box is fixedly inserted into the side wall of the eighth connecting pipe. A rotating fan is rotatably connected to the mounting box via a rotating rod. The lower end of the rotating rod is fixedly connected to a driving bevel gear, and the driving bevel gear and the driven bevel gear are meshed.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a feeding mechanism, facilitates the testing of ABB frequency converters in high-temperature and high-dust environments. At the same time, it facilitates the control of dust levels, making the testing more convenient, faster, and more effective. Furthermore, it facilitates the recycling and reuse of air and dust after testing, avoiding waste and dispersion, and making it healthier and more environmentally friendly.

[0017] The telescopic mechanism of this invention, when it is necessary to test the ABB inverter body, first places the ABB inverter body on the testing platform body. Then, the lifting module drives the lifting plate to move downward, and the telescopic mechanism drives the insulation cover to move downward. When the arc-shaped surface of the positioning block abuts against the side wall of the ABB inverter body, it can push the ABB inverter body to adjust its center. When the bottom of the insulation cover abuts against the top of the testing platform body, as the lifting plate continues to move downward, the first spring is gradually compressed, and the distance between the lifting plate and the insulation cover decreases. At this time, the inclined plate can be driven downward by the L-shaped frame, so that the moving block slides along the inclined plate to the side wall of the L-shaped frame. At the same time, the second spring is compressed. When the moving block moves, it can drive the testing head to move and insert the conductive post into the testing socket to form an electrical connection. The testing host is then used for testing, thereby facilitating the testing of the ABB inverter body.

[0018] This invention, by incorporating a switching component, allows air to enter the mounting box during ventilation or blowing. The air impacts the surface of the rotating fan, causing the rotating rod to rotate. This rotation drives the driven bevel gear, which in turn rotates the shaft and pulley, which in turn drives the belt and V-shaped frame for transport. When the V-shaped frame abuts against the sealing plate, it pushes the sealing plate into the working cover. Simultaneously, the third spring is compressed, aligning the second circular hole with the sixth connecting pipe. At this point, the switching component is opened. When the V-shaped frame passes the sealing plate, the sealing plate moves back to its original position under the action of the third spring, causing the second circular hole and the sixth connecting pipe to misalign. The switching component then disconnects. This process is repeated, allowing multiple sixth connecting pipes to open sequentially, thus improving the blowing and ventilation effects of the first circular hole on each annular cover.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-12The diagram illustrates a novel ABB inverter testing platform, comprising a testing platform body 1 and a protective shell 11. A lifting plate 14 is connected to the top of the protective shell 11 via a lifting module 13, and a thermal insulation cover 15 is connected to the bottom of the lifting plate 14 via a telescopic mechanism. Multiple temperature sensors 16 are fixedly inserted into the side wall of the thermal insulation cover 15, and a detection head 17 is inserted into the side wall of the thermal insulation cover 15 via a moving mechanism. The detection head 17 includes two symmetrically arranged conductive posts 1701, and multiple positioning blocks 18 are fixedly connected to the inner side wall of the thermal insulation cover 15. Each positioning block 18 includes an arc-shaped surface 1801. The top of the testing platform body 1 is equipped with a testing host 19. The testing head 17 and the testing host 19 are known technologies in this field and will not be described in detail here. The testing head 17 is electrically connected to the testing host 19. The side wall of the heat insulation cover 15 is equipped with a feeding mechanism for supplying hot air and dust into the heat insulation cover 15. This facilitates the testing of the ABB inverter body 12 in a high-temperature and high-dust environment. At the same time, it is easy to control the amount of dust, making the testing more convenient, faster, and more effective. Furthermore, it is easy to recycle and reuse the air and dust after testing, avoiding waste and dispersion, which is healthier and more environmentally friendly.

[0023] The feeding mechanism includes multiple hollow annular covers 203 fixedly inserted into the side wall of the insulation cover 15, and each annular cover 203 has multiple first circular holes 204 on its side wall. A hot air tank 201 is fixedly connected to the top of the detection platform body 1, and a cyclone separator 202 is fixedly connected to the top of the protective shell 11. The cyclone separator 202 is a well-known technology in this field and will not be described in detail here. A first solenoid valve 216 is fixedly connected to the top of the hot air tank 201, and a first connecting pipe 217 is fixedly connected to the upper end of the first solenoid valve 216. A second connecting pipe 214 is fixedly connected to the upper end of the first connecting pipe 217, and a second solenoid valve 215 is fixedly connected to one end of the second connecting pipe 214. The other end of the second connecting pipe 214 is fixed to... A fan 213 is connected, and a third connecting pipe 212 is fixedly connected to the other end of the fan 213. The other end of the third connecting pipe 212 is fixed to the side wall of the cyclone separator 202. A fourth connecting pipe 209 is fixedly connected to the side wall of the cyclone separator 202, and a fixed cover 208 is fixedly connected to the lower end of the fourth connecting pipe 209. A fifth connecting pipe 207 is fixedly connected between the top of the fixed cover 208 and the bottom of the cyclone separator 202. A sixth connecting pipe 205 is fixedly connected to the side wall of each annular cover 203. A seventh connecting pipe 206 is fixedly connected to the other end of the sixth connecting pipe 205, and an eighth connecting pipe 210 is fixedly connected to the side wall of the seventh connecting pipe 206. The eighth connecting pipe 210 and the fixed cover 208 are fixedly connected. A first flexible hose 211 is fixedly connected to the hot gas tank 201, and a third solenoid valve 218 is fixedly connected to the side wall of the hot gas tank 201. A second flexible hose 219 is fixedly connected between the third solenoid valve 218 and the insulation cover 15. Each sixth connecting pipe 205 has a switching component on its side wall. A mixing mechanism for mixing hot gas and dust is provided inside the fixed cover 208. When testing is required, the third solenoid valve 218 and the first solenoid valve 216 are closed, and the second solenoid valve 215 is opened. Then, the fan 213 is started for ventilation. At this time, air inside the insulation cover 15 can be absorbed through the first round hole 204 and discharged through the second solenoid valve 215. Then, the second solenoid valve 215 is closed, and the first solenoid valve 216 is opened. When the fan 213 is started, the hot air in the hot air tank 201 enters the cyclone separator 202 through the first connecting pipe 217, the second connecting pipe 214 and the third connecting pipe 212, and then enters the inner fixed cover 208 through the fourth connecting pipe 209. At the same time, the dust in the cyclone separator 202 can enter the fixed cover 208 through the fifth connecting pipe 207, so that the dust and hot air are mixed. The hot air with dust can enter the eighth connecting pipe 210 through the hose 211, and then enter the annular cover 203 through the seventh connecting pipe 206 and the sixth connecting pipe 205, and blow out the first round hole 204, thus facilitating the testing of the ABB inverter body 12 in a high temperature and high dust environment.

[0024] The mixing mechanism includes a sliding plate 301 slidably connected within a fixed cover 208. A metering groove 303 is formed on the top of the sliding plate 301, and a filter hole 304 is formed on the side of the metering groove 303 near the fourth connecting pipe 209. A moving module 302 is provided between the sliding plate 301 and the fixed cover 208. The moving module 302 drives the sliding plate 301 to move. When the metering groove 303 is aligned with the lower end of the fifth connecting pipe 207, dust in the cyclone separator 202 can enter the metering groove 303 through the fifth connecting pipe 207 and fill it. Then, the moving module 302 drives the sliding plate 301 to continue moving. When the metering tank 303 is aligned with the fourth connecting pipe 209, the hot air in the fourth connecting pipe 209 can enter the metering tank 303 through the filter hole 304, thereby blowing up the dust in the metering tank 303 and mixing the dust with the hot air. The hot air with dust can enter the eighth connecting pipe 210 through the hose 211, and then enter the annular cover 203 through the seventh connecting pipe 206 and the sixth connecting pipe 205, blowing out the first round hole 204. This facilitates the testing of the ABB inverter body 12 in a high-temperature and high-dust environment, and makes it easier to control the amount of dust, making the testing more convenient, faster, and more effective.

[0025] The telescopic mechanism includes two symmetrically arranged sleeves 401 fixedly connected to the bottom of the lifting plate 14, and each sleeve 401 is fitted with a sleeve rod 402. The lower end of the sleeve rod 402 is fixed to the top of the insulation cover 15, and the side wall of each sleeve 401 is fitted with a first spring 403. When it is necessary to test the ABB inverter body 12, the ABB inverter body 12 is first placed on the test platform body 1. Then, the lifting module 13 drives the lifting plate 14 to move downward, and the telescopic mechanism drives the insulation cover 15 to move downward. When the arc surface 1801 of the positioning block 18 abuts against the side wall of the ABB inverter body 12, it can push the ABB inverter body 12 to perform centering adjustment. When the bottom of the insulation cover 15 abuts against the top of the test platform body 1, as the lifting plate 14 continues to move downward, the first spring 403 is gradually compressed, and the distance between the lifting plate 14 and the insulation cover 15 becomes smaller.

[0026] The moving mechanism includes a moving block 501 fixedly sleeved on the side wall of the detection head 17, and a first reset mechanism is provided between the moving block 501 and the heat insulation cover 15. An L-shaped frame 502 is fixedly connected to the side wall of the lifting plate 14, and an inclined plate 503 is fixedly connected to the bottom of the L-shaped frame 502. When the distance between the lifting plate 14 and the heat insulation cover 15 decreases, the inclined plate 503 can be moved downward by the L-shaped frame 502, so that the moving block 501 slides along the inclined plate 503 to the side wall of the L-shaped frame 502. When the moving block 501 moves, it can drive the detection head 17 to move and insert the conductive post 1701 into the detection socket 1201 to form an electrical connection.

[0027] The first reset mechanism includes two symmetrically arranged first T-shaped guide rods 601 inserted into the side wall of the moving block 501. The first T-shaped guide rods 601 are fixed to the side wall of the heat insulation cover 15, and a second spring 602 is sleeved on the side wall of each first T-shaped guide rod 601, which guides and resets the movement of the moving block 501.

[0028] The switching assembly includes a working cover 701 fixedly inserted into the side wall of the sixth connecting pipe 205, and a sealing plate 702 connected inside the working cover 701 via a second reset mechanism. The side wall of the sealing plate 702 has a second circular hole 703, and the movement of the sealing plate 702 is driven by a pushing mechanism. The pushing mechanism pushes the sealing plate 702 to slide into the working cover 701, so that the second circular hole 703 is aligned with the sixth connecting pipe 205. At this time, the switching assembly is opened, and the sealing plate 702 can be moved and reset under the action of the second reset mechanism, so that the second circular hole 703 is misaligned with the sixth connecting pipe 205. At this time, the switching assembly is disconnected.

[0029] The second reset mechanism includes two symmetrically arranged first connecting blocks 801 fixedly connected to the side wall of the sealing plate 702, and a second T-shaped guide rod 802 fixedly connected to the side wall of each first connecting block 801. A second connecting block 803 is sleeved on the side wall of the second T-shaped guide rod 802, and the second connecting block 803 is fixed to the side wall of the working cover 701. A third spring 804 is sleeved on the side wall of each second T-shaped guide rod 802, which guides and resets the movement of the sealing plate 702.

[0030] The pushing mechanism includes two symmetrically arranged U-shaped frames 901 fixedly connected to the side wall of the heat insulation cover 15. The side wall of each U-shaped frame 901 is rotatably connected to a pulley 903 via a rotating shaft 902. The side wall of the two pulleys 903 is fitted with a belt 904. The side wall of each belt 904 is fixedly connected to multiple sets of pushing components. Each set of pushing components includes multiple arrayed V-shaped frames 905. The rotation of the rotating shaft 902 is driven by a driving mechanism. Driven by the driving mechanism, the rotating shaft 902 and the pulleys 903 rotate, thereby driving the belt 904 and the V-shaped frames 905 to transport. When the V-shaped frame 905 abuts against the sealing plate 702, it can push the sealing plate 702 to slide into the working cover 701.

[0031] The drive mechanism includes a driven bevel gear 1001 fixedly connected to the end of the rotating shaft 902, and a mounting box 1002 is fixedly inserted into the side wall of the eighth connecting pipe 210. A rotating fan 1004 is rotatably connected to the mounting box 1002 via a rotating rod 1003. A driving bevel gear 1005 is fixedly connected to the lower end of the rotating rod 1003, and the driving bevel gear 1005 meshes with the driven bevel gear 1001. When the fan is being ventilated or blown, when air enters the mounting box 1002, it impacts the surface of the rotating fan 1004, causing the rotating rod 1003 to rotate. When the rotating rod 1003 rotates, it drives the driven bevel gear 1001 to rotate, thereby driving the rotating shaft 902 and the pulley 903 to rotate.

[0032] Working Principle: When testing the ABB inverter body 12, first place the ABB inverter body 12 on the testing platform body 1. Then, the lifting module 13 drives the lifting plate 14 downwards, and the telescopic mechanism drives the insulation cover 15 downwards. When the arc-shaped surface 1801 of the positioning block 18 abuts against the side wall of the ABB inverter body 12, it can push the ABB inverter body 12 to center. When the bottom of the insulation cover 15 abuts against the top of the testing platform body 1, and the lifting plate 14 continues to move downwards... The first spring 403 is gradually compressed, and the distance between the lifting plate 14 and the heat preservation cover 15 becomes smaller. At this time, the inclined plate 503 can be moved downward by the L-shaped frame 502, so that the moving block 501 slides along the inclined plate 503 to the side wall of the L-shaped frame 502. At the same time, the second spring 602 is compressed. When the moving block 501 moves, it can drive the detection head 17 to move and insert the conductive post 1701 into the detection socket 1201 to form an electrical connection. The detection host 19 is used for detection, which facilitates the detection of the ABB inverter body 12. When testing is required, the third solenoid valve 218 and the first solenoid valve 216 are closed, and the second solenoid valve 215 is opened. Then, the fan 213 is started to perform a ventilation operation. At this time, the air inside the insulation cover 15 can be absorbed through the first round hole 204 and discharged through the second solenoid valve 215. Then, the second solenoid valve 215 is closed, the first solenoid valve 216 is opened, and the fan 213 is started to perform a blowing operation. At this time, the hot air in the hot air tank 201 can enter the cyclone separator 202 through the first connecting pipe 217, the second connecting pipe 214 and the third connecting pipe 212, and then enter the fourth connecting pipe 209. At this time, the sliding plate 301 can seal the end of the fourth connecting pipe 209. Then, the sliding plate 301 is moved by the moving module 302. When the quantitative tank 303 is aligned with the lower end of the fifth connecting pipe 207, the dust in the cyclone separator 202 can enter the quantitative tank 303 through the fifth connecting pipe 207 and fill it. Then, the sliding plate 301 continues to move through the moving module 302. When the quantitative tank 303 is aligned with the fourth connecting pipe 209, the hot air in the fourth connecting pipe 209 can enter the quantitative tank 303 through the filter hole 304, thereby blowing up the dust in the quantitative tank 303 and mixing the dust and hot air. The hot air with dust can enter the eighth connecting pipe 210 through the hose 211, and then enter the annular cover 203 through the seventh connecting pipe 206 and the sixth connecting pipe 205, and blow out the first round hole 204. This makes it easier to test the ABB inverter body 12 in a high temperature and high dust environment, and makes it easier to control the amount of dust, making the test more convenient, faster and more effective. After the test is completed, the fan 213 can be started to perform the exhaust operation. At the same time, the sliding plate 301 is moved by the moving module 302, so that the sliding plate 301 opens the end of the fourth connecting pipe 209 and opens the third solenoid valve 218. At this time, the air and dust in the heat insulation cover 15 can be circulated. Meanwhile, the dust can be separated by the action of the cyclone separator 202. After the dust is collected, the third solenoid valve 218 is closed, and the air in the heat insulation cover 15 can be drawn back into the hot air tank 201. This facilitates the recycling and reuse of the air and dust after the test, avoids waste and dispersion, and is healthier and more environmentally friendly. Furthermore, during ventilation or blowing, when air enters the mounting box 1002, it impacts the surface of the rotating fan 1004, causing the rotating rod 1003 to rotate. When the rotating rod 1003 rotates, it drives the driven bevel gear 1001 to rotate, thereby driving the rotating shaft 902 and pulley 903 to rotate, which in turn drives the belt 904 and V-shaped frame 905 for conveying. When the V-shaped frame 905 abuts against the sealing plate 702, it pushes the sealing plate 702 to slide into the working cover 701. Simultaneously, the... When the three springs 804 are compressed, the second round hole 703 is aligned with the sixth connecting tube 205. At this time, the on / off assembly is opened. When the V-shaped frame 905 passes the sealing plate 702, the sealing plate 702 can move and reset under the action of the third spring 804, so that the second round hole 703 and the sixth connecting tube 205 are misaligned. At this time, the on / off assembly is disconnected. By repeating this process, multiple sixth connecting tubes 205 can be opened sequentially, thereby improving the blowing and exhaust effects of the first round hole 204 on each annular cover 203.
