Description

Technical Field

[0001] This utility model relates to the technical field of transformer testing equipment, specifically a box-type transformer testing equipment. Background Technology

[0002] A box-type transformer (referred to as a box-type transformer) is a compact set of complete power distribution equipment that integrates transformers, high-voltage switchgear, low-voltage power distribution devices, etc. into a sealed tempered box. It has a fully enclosed structure that is moisture-proof, dust-proof, rodent-proof, and fireproof. In order to ensure the safe and stable operation of the equipment and prevent power outages caused by potential faults, a comprehensive inspection of the box-type transformer is required after the production of the box-type transformer is completed. In the prior art, patent CN119087076A discloses an online transformer testing device, including a testing chamber, a conveyor belt, a motor, and a testing control center. The testing chamber is equipped with a first robotic arm, a second robotic arm, a camera, a high-voltage power line electrode head, a low-voltage power line electrode head, a telescopic rod, and a push plate. The testing control center sends a switch control signal to the motor, which drives the conveyor belt to operate. The transformer under test is transported to the testing chamber via the conveyor belt. When the camera detects the transformer under test, the testing control center sends a telescopic control signal to the telescopic rod, which pushes the push plate installed at the front end to fix the transformer under test. The following are the disadvantages of this type of online transformer testing equipment: when testing the transformer, the motor needs to be turned off to stop the conveyor belt, and then the transformer needs to be fixed for testing. After the test is completed, the motor needs to be restarted to turn on the conveyor belt to transport the transformer. Frequent start and stop reduce the testing efficiency of the transformer. To address this, we propose a box-type transformer testing equipment. Utility Model Content

The rear end of the output shaft of the motor 19 is fixedly connected to the front end of the drive shaft 9.

The output shaft of motor 19 rotates, driving transmission shaft 9 to rotate, causing right-side rotating roller 2 to rotate, which in turn drives transmission belt 3 to rotate. Simultaneously, sprocket 10 rotates, and under the action of chain 13, it drives sprockets 11 and 12 to rotate synchronously, causing right-side rotating shaft 6 to rotate. This rotates screw 17, causing slider 18 to move along the direction of screw 17, driving sprocket 12 to move, keeping chain 13 taut, and driving right-side rotating roller 7 to rotate, causing transmission belt 22 to connect with transmission belt 3. The detection platform 1 rotates synchronously. A second mounting base 16 is fixedly connected to the front surface of the detection platform 1. A screw 17 is rotatably connected inside the second mounting base 16 (corrugated tubes are fixedly connected between the left and right surfaces of the slider 18 and the inner wall of the second mounting base 16, and the corrugated tubes are all sleeved on the outer surface of the screw 17 to protect the screw 17 and prevent external impurities from sticking to the outer surface of the screw 17 and causing the screw 17 to jam). A slider 18 is threadedly connected to the outer surface of the screw 17. The lower surface of the slider 18 is slidably connected to the inner wall of the second mounting base 16. A sprocket 3 12 is rotatably connected to the rear end of the slider 18. The platform also includes a detection mechanism 8. The detection mechanism 8 includes a connecting rod 81, a first mounting base 82, a movable block 83, a connecting frame 84, and connecting contact points 85. The connecting rods 81 are all fixedly connected to the rear surface of the conveyor belt 22. The rear end of each connecting rod 81 is fixedly connected to the first mounting base 82. The movable block 83 is slidably connected inside each first mounting base 82. The front surface of each movable block 83 is fixedly connected to the connecting frame 84. Connecting contact points 85 are slidably connected inside each connecting frame 84. A spring is fixedly connected between the side of each connecting contact point 85 closest to the conveyor belt 22 and the inner wall of the connecting frame 84. The detection mechanism 8 also includes a limiting pin 86, a limiting groove 87, a fixed cylinder 88, and a second spring 89. All 86 pins are fixedly connected to the rear surface of the movable block 83. A limiting groove 87 is formed in the middle of the inner rear surface of the mounting bracket 5, and the limiting pins 86 are all installed in conjunction with the limiting groove 87. A fixed cylinder 88 is fixedly connected inside the first mounting base 82. The end of the movable block 83 closest to the second conveyor belt 22 is slidably connected to the adjacent fixed cylinder 88 on the same side. A spring 89 is fixedly connected between the end of the movable block 83 closest to the second conveyor belt 22 and the inner wall of the fixed cylinder 88. A transformer capacity detector 20 is fixedly connected to the rear surface of the mounting bracket 5. A fixed contact 14 is fixedly connected to the inner rear surface of the mounting bracket 5. A movable contact 15 is fixedly connected to the rear surface of the first mounting base 82. The movable contact 15 is connected to the fixed contact 20. Contact 14 is installed in conjunction with the output terminal of the movable contact 15, which is electrically connected to the input terminal of the connecting contact 85 located on the same first mounting base 82. The input terminal of the fixed contact 14 is electrically connected to the output terminal of the transformer capacity detector 20, which is electrically connected to the output terminal of the control switch group 21. Conveyor belt 3 drives the box-type transformer to move, and conveyor belt 22 drives the detection mechanism 8 to move. The control switch group 21 is operated to start the transformer capacity detector 20. When the box-type transformer moves to the middle of the detection platform 1, the detection mechanism 8 corresponding to the upper side of the box-type transformer also moves to the middle of the detection platform 1. At this time, the movable contact 15 and the fixed contact 14, which are redistributed on the detection platform 1, are connected. When the two contacts are in contact, the limiting pin 86 moves into the limiting groove 87. Under the limiting action of the limiting groove 87, the limiting pin 86 moves downward, causing the movable block 83 to move downward. The spring 89 relaxes, causing the connecting frame 84 to move downward, so that the connecting contact point 85 moves downward and contacts the low-voltage side port of the box-type transformer. The spring 89 applies a downward elastic force to the connecting contact point 85, so that the connecting contact point 85 and the low-voltage side port of the transformer are stably connected. At this time, the output end of the transformer capacity detector 20 is connected to the low-voltage side port of the transformer through the fixed contact 14, the movable contact 15 and the connecting contact point 85. The transformer capacity detector 20 indirectly calculates its actual capacity by measuring the electrical parameters of the transformer.During testing, the instrument first injects a test signal of a specific frequency into the low-voltage side of the transformer, and simultaneously collects data such as input voltage, current, and phase angle. Through algorithms such as Fourier transform, it calculates key parameters of the transformer, such as no-load loss, load loss, and impedance voltage. Combining the built-in transformer equivalent circuit model and industry standards, the instrument utilizes the correlation between these parameters and rated capacity. By comparing the measured data with typical values ​​in the standard database, it finally calculates the actual operating capacity of the transformer, thus realizing the testing of the box-type transformer. Afterward, the box-type transformer and the testing mechanism 8 continue to move, the limit pin 86 disengages from the limit groove 87, the spring 89 contracts, driving the movable block 83 to move upward, causing the connecting frame 84 to move upward, driving the connecting contact 85 to move upward, separating the connecting contact 85 from the low-voltage side port of the transformer, and separating the movable contact 15 from the fixed contact 14. This process is repeated to achieve continuous testing of the box-type transformer.

[0016] The working principle of the box-type transformer testing equipment provided by this utility model is as follows: When performing the testing operation of the box-type transformer, the box-type transformer is placed in the placement slot 4. The control switch group 21 is operated to start the motor 19. The output shaft of the motor 19 rotates, driving the transmission shaft 9 to rotate, causing the rotating roller 2 on the right to rotate, driving the transmission belt 3 to rotate. At the same time, the sprocket 10 rotates, and under the action of the chain 13, it drives the sprockets 11 and 12 to rotate synchronously, causing the rotating shaft 6 on the right to rotate. The rotatable screw 17 rotates, causing the slider 18 to move along the direction of the screw 17, driving the sprocket 12 to move, keeping the chain 13 taut, driving the rotating roller 7 on the right to rotate, causing the conveyor belt 22 and the conveyor belt 3 to rotate synchronously. The conveyor belt 3 drives the box-type transformer to move, and the conveyor belt 22 drives the testing mechanism 8 to move. The control switch group 21 is operated to start the transformer capacity tester 20. When the box-type transformer is tested... When the transformer moves to the middle of the testing platform 1, the corresponding testing mechanism 8 on the upper side of the box-type transformer also moves to the middle of the testing platform 1. At this time, the movable contact 15 and the fixed contact 14, which are redistributed on the testing platform 1, come into contact. The limiting pin 86 moves into the limiting groove 87. Under the limiting action of the limiting groove 87, the limiting pin 86 moves downward, causing the movable block 83 to move downward. The spring 89 relaxes, causing the connecting frame 84 to move downward, so that the connecting contact 85 moves downward and comes into contact with the low-voltage side port of the box-type transformer. The spring 85 applies a downward elastic force to the connecting contact 85, so that the connecting contact 85 and the low-voltage side port of the transformer remain stably connected. At this time, the output end of the transformer capacity tester 20 is connected to the low-voltage side port of the transformer through the fixed contact 14, the movable contact 15 and the connecting contact 85. The transformer capacity tester 20 indirectly calculates the actual capacity by measuring the electrical parameters of the transformer. During testing, the instrument first injects a test signal of a specific frequency into the low-voltage side of the transformer, and simultaneously collects data such as input voltage, current, and phase angle. Through algorithms such as Fourier transform, it calculates key parameters of the transformer, such as no-load loss, load loss, and impedance voltage. Combining the built-in transformer equivalent circuit model and industry standards such as IEC or GB, the instrument utilizes the correlation between these parameters and rated capacity. By comparing the measured data with typical values ​​in the standard database, it finally calculates the actual operating capacity of the transformer, thus realizing the testing of the box-type transformer. Afterward, the box-type transformer and the testing mechanism 8 continue to move, the limit pin 86 disengages from the limit groove 87, the spring 89 contracts, driving the movable block 83 to move upward, causing the connecting frame 84 to move upward, driving the connecting contact 85 to move upward, separating the connecting contact 85 from the low-voltage side port of the transformer, and separating the movable contact 15 from the fixed contact 14. This process is repeated to achieve continuous testing of the box-type transformer.

[0017] It is worth noting that the motor 19 disclosed in the above embodiments is YE2-80M2-2-B14, the transformer capacity detector 20 is CS2674AX, and the control switch group 21 is provided with control buttons that correspond one-to-one with the motor 19 and the transformer capacity detector 20 and are used to control their switching.

[0018] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
