Description

Technical Field

[0001] This invention relates to the field of transformer testing technology, specifically to a device and method for detecting component wear in transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core. After long-term use, transformers will wear out and need to be inspected regularly. During the inspection process, a testing device is required.

[0003] In Chinese patent application number CN202411252485.3, entitled "An Electronic Component Inspection Device", this patent enables preliminary inspection of electronic components using one inspection camera A and two inspection cameras B. After the preliminary inspection, the electronic components are gripped by a clamping mechanism, and the clamping mechanism is flipped using a reduction motor and a linkage mechanism to achieve automatic flipping of the electronic components without manual intervention. This reduces the intensity of manual labor, saves time and effort, and improves the continuous inspection of electronic components, effectively improving the inspection efficiency. The other inspection camera A enables secondary inspection of the flipped electronic components, achieving comprehensive defect detection of electronic components.

[0004] When testing transformers, this patent can only test smaller electrical components by flipping them, and cannot test larger transformers. Existing transformer testing devices cannot test transformers of different specifications, and have a limited scope of application. Furthermore, after a period of use, existing transformer terminals often accumulate dirt, and when existing testing devices are directly connected to the terminals, the test results are prone to deviation, affecting the test results.

A lifting rail is installed on the top of the support frame. A lifting block is slidably installed inside the lifting rail.

[0017] An installation plate is connected between two adjacent lifting blocks. A swing base is installed at both ends of one side of the installation plate. A swing frame is rotatably installed on one side of the swing base. An infrared thermal imager is installed at one end of the swing frame. An industrial X-ray machine is installed at the other end of the swing frame. Connecting plates are connected to both ends of the rotating shaft of the swing frame.

[0020] According to the above technical solution, the bottom end of the lifting screw is connected to a drive pulley, the bottom end of the cam column is connected to a driven pulley, and a linkage belt is wrapped between the drive pulley and the adjacent driven pulley;

[0021] The input terminals of the lifting electric actuator, translation electric actuator, servo motor, docking electric actuator, cleaning motor, heating wire, air pump, lifting motor, infrared thermal imager, and industrial X-ray machine are electrically connected to the external power supply output terminal through the controller.

[0022] This invention also provides a method for detecting component wear in a transformer, which involves construction operations based on the above technical solution, including the following steps:

[0023] S1. Fixed positioning process: The transformer is placed neatly on the top of the mobile vehicle, and the wheels of the mobile vehicle enter the top of the mobile rail, so that the wiring terminal in the middle of the transformer and the probe on one side of the fixed seat are on the same vertical plane.

[0024] S2, Terminal cleaning process: The electric rail, translation electric push rod, and servo motor operate. The socket hole directly below the fixed base is aligned with the middle terminal of the transformer, and the socket hole directly below the moving block is aligned with the other two terminals. The lifting electric push rod operates, and the socket hole is fitted onto the outside of the terminal. The cleaning motor drives the cleaning sponge to rotate.

[0025] S3, Terminal Drying Process: The lifting electric push rod drives the jet head to align with the wiring terminal. The air pump and heating wire run, and the heated air is sprayed out from the jet head. The cleaning motor drives the jet head to rotate.

[0026] S4. Transformer testing process: The lifting electric push rod drives the jet head to disengage from the terminal block; the horizontal electric push rod drives the probe head to align with the terminal block; the docking electric push rod drives the probe head to dock with the terminal block.

[0027] S5, Loss Positioning Process: The infrared thermal imager and industrial X-ray machine are in operation. The lifting motor drives the lifting screw and cam column to rotate, and the infrared thermal imager and industrial X-ray machine swing.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. Equipped with a detection and calibration component, the assembly frame is moved to the top of the transformer via an electric rail, and the translational electric push rod moves the assembly frame to align the socket hole directly below the fixed base with the terminal block in the middle of the transformer. In conjunction with the servo motor, the socket hole directly below the moving block is aligned with the other two terminals. The device can still be used when the distance between the transformer terminals is different, and the device has a wide range of applications.

[0030] After aligning the three terminals, the lifting electric push rod lowers the cleaning sponge, which then fits over the terminals. The cleaning motor rotates the sponge to clean the terminals. After cleaning, the lifting electric push rod aligns the air jet with the terminals, and an air pump supplies air into the heating element. The air is heated by the heating wire and then ejected through the air jet. Simultaneously, the cleaning motor rotates the air jet, achieving the cleaning and drying of the transformer terminals. This prevents inaccurate transformer test results due to dirt on the terminal surface when the probe contacts the transformer terminals, improving the accuracy and effectiveness of transformer testing. The transformer can be tested immediately after the terminals are cleaned and dried, avoiding secondary contamination and improving the testing effect. Furthermore, it eliminates the need for manual connection and fixation of the probe to the terminals, reducing labor intensity.

[0031] The moisturizing ring box is filled with anhydrous ethanol. Every once in a while, anhydrous ethanol is dripped from the metering dropper into the cleaning sponge to keep the cleaning sponge moist and enable the device to clean continuously. When the cleaning sponge needs to be replaced, simply rotate the connecting screw to remove the old cleaning sponge and install the new one. It is convenient and quick.

[0032] 2. Equipped with an irradiation detection component, the infrared thermal imager and industrial X-ray imaging device move up and down by rotating the lifting screw driven by the lifting motor. During transformer inspection, the infrared thermal imager scans and locates the overheated spots of the transformer, making it easier to pinpoint the short circuit location of the transformer's silicon steel sheets. The industrial X-ray imaging device analyzes the changes after X-rays penetrate the transformer windings to determine the shape of the transformer windings and whether the windings have deformed. In subsequent transformer maintenance, maintenance workers can quickly find the loss points, improving the speed of transformer maintenance.

[0033] Driven by the linkage belt, the lifting motor drives the driven pulley and cam column to rotate. The rotation of the cam column drives the actuating rod to rotate. Under the elastic reset action of the swing spring, when the mounting plate moves up and down, the actuating rod is in real time in contact with the outer side of the cam column, realizing the back and forth swing of the swing frame. The infrared thermal imager and industrial X-ray imaging device also swing back and forth during their up and down movement, making the illumination range of the infrared thermal imager and industrial X-ray imaging device wider, avoiding the generation of blind spots, and improving the detection effect of the device.

[0034] In summary, when the detection and correction component detects the losses of transformer components, the irradiation detection component simultaneously locates the losing components. With the two components working together, the device can quickly detect and locate the losing components of the transformer. Combined with the mobile cart to move the transformer, it facilitates the manufacturer's maintenance of the transformer, shortens the maintenance time, and improves the manufacturer's efficiency.

[0053] Both the fixed base 205 and the movable block 206 are equipped with docking electric actuators 210 on one side. The output end of the docking electric actuator 210 is connected to a probe head 211. The probe head 211 is connected to an external transformer capacity tester.

The translation electric actuators 203 can drive the assembly frame 204 to move, thereby driving the probe head 211 and the cleaning sponge 215 to move.

[0054] A moisturizing ring box 217 is connected to the outside of the connecting screw 214. A metering dropper 218 is connected to the bottom side of the moisturizing ring box 217. The metering dropper 218 is located at the top of the cleaning sponge 215. The moisturizing ring box 217 is filled with anhydrous ethanol.

An air pump 228 is installed on one side of the top of the assembly frame 202. The air outlet of the air pump 228 is connected to one end of the heating tube 225 through a hose. The air pump 228 can deliver air into the heating tube 225. After being heated by the electric heating wire 227, the air flows through the air distribution hose 226 and the drying ring box 220 into the air jet pipe 222, and finally is ejected from the air jet head 223. The ejected hot air can dry the cleaned transformer terminals.

[0057] The bottom of the assembly frame 202 is provided with an irradiation detection mating assembly 3, which includes a moving rail 301, a support frame 302, a lifting rail 303, a lifting block 304, a lifting screw 305, a lifting motor 306, a mounting plate 307, a swing base 308, a swing frame 309, an infrared thermal imager 310, an industrial X-ray machine 311, a connecting piece 312, a swing spring 313, a toggle lever 314, a drive pulley 315, a cam column 316, a driven pulley 317, a linkage belt 318, and a moving cart 319.

[0058] The assembly frame 202 has two movable rails 301 installed on the bottom sides. A support frame 302 is installed on one side of the movable rail 301. There are four support frames 302. A lifting rail 303 is installed on the top of the support frame 302. A lifting block 304 is slidably installed inside the lifting rail 303. A lifting screw 305 is rotatably installed inside the lifting rail 303. The lifting screw 305 is connected to the adjacent lifting block 304 through a screw hole.

[0060] An installation plate 307 is connected between two adjacent lifting blocks 304. A swing base 308 is installed at both ends on one side of the installation plate 307. A swing frame 309 is rotatably installed on one side of the swing base 308. An infrared thermal imager 310 is installed at one end of the swing frame 309. When the transformer is connected for testing, the grounding current suddenly increases and local temperature rises abnormally. The overheating point of the transformer is located by infrared scanning, which makes it easier to locate the short circuit position of the silicon steel sheet of the transformer. An industrial X-ray imaging device 311 is installed at the other end of the swing frame 309. The industrial X-ray imaging device 311 is an X-ray imaging device.

The controller can control each electrical component, which facilitates the automated control of the device.

[0063] like Figure 10 As shown, a method for detecting component wear in a transformer includes the following steps:

[0064] S1. Fixed positioning process: The transformer is placed neatly on the top of the mobile vehicle 319, and the wheels of the mobile vehicle 319 enter the top of the mobile rail 301, so that the wiring terminal in the middle of the transformer and the probe head 211 on one side of the fixed seat 205 are on the same vertical plane.

[0065] S2, Terminal cleaning process: Electric rail 1, translation electric push rod 203, and servo motor 209 run. The socket 216 directly below the fixed base 205 is aligned with the middle terminal of the transformer. The socket 216 directly below the moving block 206 is aligned with the other two terminals. The lifting electric push rod 201 runs. The socket 216 is fitted onto the outside of the terminal. The cleaning motor 212 drives the cleaning sponge 215 to rotate.

[0066] S3, Terminal drying process: The lifting electric push rod 201 drives the jet head 223 to align with the terminal, the air pump 228 and the heating wire 227 run, the heated air is sprayed out from the jet head 223, and the cleaning motor 212 drives the jet head 223 to rotate.

[0067] S4. Transformer testing process: Lifting electric push rod 201 drives jet head 223 to disengage from terminal block, translation electric push rod 203 drives probe head 211 to align with terminal block, docking electric push rod 210 drives probe head 211 to dock with terminal block;

[0068] S5, Loss Positioning Process: Infrared thermal imager 310 and industrial imaging camera 311 operate, lifting motor 306 drives lifting screw 305 and cam column 316 to rotate, and infrared thermal imager 310 and industrial imaging camera 311 swing.

[0069] The working principle and usage process of this invention: When testing a transformer, first clean the bushing terminals of the transformer, place the transformer neatly on top of the moving cart 319, the wheels of the moving cart 319 enter the top of the moving rail 301, and the moving cart 319 moves along the moving rail 301 so that the middle terminal of the transformer and the probe 211 on one side of the fixed base 205 are on the same vertical plane.

[0070] During cleaning, the electric rail 1 moves the assembly frame 202 to the top of the transformer, and the translational electric push rod 203 moves the assembly frame 204, aligning the socket 216 directly below the fixed seat 205 with the terminal block in the middle of the transformer. Then, the servo motor 209 operates, rotating the adjusting screw 208. Under the limiting guidance of the guide slide 207, the moving block 206 moves along the guide slide 207, aligning the socket 216 directly below the moving block 206 with the other two terminals, thus aligning the socket 216 directly below the fixed seat 205 with the terminal block in the middle of the transformer. The wire terminals, in conjunction with the servo motor 209 driving the moving block 206, align the socket 216 directly below with the other two wire terminals. The device can still be used when the distance between the wire terminals of the detection transformer is different. Compared with the prior art, the device has a wider range of applications. After the three wire terminals are aligned, the lifting electric push rod 201 moves and drives the cleaning sponge 215 down, so that the socket 216 fits on the outside of the wire terminals. Then, the cleaning motor 212 drives the cleaning sponge 215 to rotate. The cleaning sponge 215 contains anhydrous ethanol, which can clean the wire terminals.

[0071] The metering dropper 218 is located at the top of the cleaning sponge 215. The moisturizing ring box 217 is filled with anhydrous ethanol. Anhydrous ethanol can be dripped from the metering dropper 218 at regular intervals to soak into the cleaning sponge 215, keeping the cleaning sponge 215 moist. When the cleaning sponge 215 needs to be replaced, simply rotate the connecting screw 214 to remove the old cleaning sponge 215 and install the new cleaning sponge 215. A sealing plug 219 is connected to one side of the top of the moisturizing ring box 217. The sealing plug 219 can seal the moisturizing ring box 217. When the anhydrous ethanol inside the moisturizing ring box 217 is used up, the sealing plug 219 can be removed to replenish the anhydrous ethanol, which is convenient and quick.

[0072] After cleaning, the lifting electric push rod 201 drives the cleaning sponge 215 to detach from the terminal block, so that the jet nozzle 223 is aligned with the terminal block. Then, the air pump 228 delivers air into the heating tube 225. After being heated by the heating wire 227, the air flows through the air distribution hose 226 and the drying ring box 220 into the jet pipe 222, and finally sprays out from the jet nozzle 223. At the same time, the cleaning motor 212 drives the threaded cylinder 213 to rotate. Under the connection of the linkage rod 224, the jet pipe 222, the jet nozzle 223 and the rotating ring 221 rotate. The hot air sprayed out by the jet nozzle 223 dries the cleaned transformer terminal block, thus cleaning and drying the transformer terminal block. When the probe 211 comes into contact with the transformer terminal block, it avoids inaccurate transformer detection results due to stains on the surface of the terminal block, thus improving the accuracy of transformer detection and the detection effect.

[0073] Subsequently, the lifting electric push rod 201 drives the jet head 223 to disengage from the terminal block. Then, the translation electric push rod 203 moves the assembly frame 204, aligning the probe head 211 with the terminal block. Next, the docking electric push rod 210 lowers the probe head 211, docking it with the terminal block. The probe head 211 is then connected to an external transformer capacity tester, which can test the specific parameters of the transformer to determine the performance loss of the transformer components. After the terminal block is cleaned and dried, the transformer can be tested immediately, avoiding secondary contamination of the terminal block, improving the testing effect, and eliminating the need for manual connection and fixation of the probe head 211 to the terminal block for testing, reducing manual labor intensity and making it convenient and quick.

[0074] During transformer testing, the infrared thermal imager 310 and the industrial X-ray imaging device 311 also operate simultaneously. The lifting motor 306 drives the lifting screw 305 to rotate, and the lifting block 304 moves up and down inside the lifting rail 303, thereby driving the infrared thermal imager 310 and the industrial X-ray imaging device 311 to move up and down. When the transformer is connected for testing, the grounding current suddenly increases and is accompanied by abnormal local temperature rise. The infrared thermal imager 310 scans and locates the overheated spot of the transformer, which makes it easier to pinpoint the short circuit location of the transformer's silicon steel sheets. The industrial X-ray imaging device 311 is an X-ray imaging device. By analyzing the changes after X-rays penetrate the transformer windings, the shape of the transformer windings can be determined, and it can be determined whether the transformer windings have been deformed. In subsequent transformer maintenance, maintenance workers can quickly find the loss point, improving the transformer maintenance speed.

[0075] When the lifting screw 305 rotates, it also drives the drive pulley 315 to rotate. Under the driving action of the linkage belt 318, the lifting motor 306 drives the driven pulley 317 and the cam column 316 to rotate. The rotation of the cam column 316 drives the actuating rod 314 to rotate. The actuating rod 314 drives the swing spring 313 to rotate. Under the elastic reset action of the swing spring 313, when the mounting plate 307 moves up and down, the actuating rod 314 is in real time in contact with the outer side of the cam column 316, realizing the back and forth swing of the swing frame 309, which in turn drives the infrared thermal imager 310 and the industrial imaging camera 311 to swing back and forth. The infrared thermal imager 310 and the industrial imaging camera 311 also swing back and forth during the up and down movement process, so that the illumination range of the infrared thermal imager 310 and the industrial imaging camera 311 is wider, avoiding the generation of blind spots, and the detection effect of the device is better.
