Description

Technical Field

[0001] This disclosure relates to the field of transformer oil quality testing technology, and in particular to a transformer oil transmittance testing device. Background Technology

[0002] Transformer oil, as the core insulation and heat dissipation medium of power transformers, has a light transmittance that directly reflects the content of impurities, moisture, and aging products in the oil. It is a key indicator for evaluating the insulation performance, heat dissipation performance, and operating status of transformer oil. When impurities or moisture are mixed into transformer oil or when aging occurs, the light transmittance will decrease, which will lead to faults such as insulation breakdown and heat dissipation failure, seriously threatening the safe and stable operation of the power system.

[0003] Current conventional methods for testing the transmittance of transformer oil mostly employ standard cuvettes and are generally conducted under static, single-point sampling conditions. This testing mode relies solely on single-point sampling to obtain test samples, resulting in limited sample coverage and insufficient representativeness of the test data. It is difficult to comprehensively and objectively reflect the overall actual transmittance performance of the transformer oil. Furthermore, existing testing methods have poor adaptability, failing to conveniently perform comparative testing of transformer oil under multiple temperature gradients, such as ambient temperature and actual equipment operating temperature. This makes it difficult to accurately assess the impact of temperature changes on the transmittance and quality of transformer oil, significantly limiting the comprehensiveness and practicality of the testing. Summary of the Invention

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1.

Combined with the positioning function of the first positioning rod and the first positioning groove, it ensures the accuracy of detection and measurement. 2. This invention achieves full automation of the entire process of loading and unloading, heating, detection, and multi-point sampling through the binding and limiting of the material binding frame, the automatic clamping and releasing of the dual-axis electric cylinder, and the precise drive of the servo motor. It requires minimal manual intervention and effectively reduces human error. At the same time, the adjustable design of the movable plate adapts to different specifications of detection containers, achieving flexible adaptation of visual inspection, further improving the intelligence of the device and reducing the labor intensity of operators. 3. This invention, by setting two sets of feeding frames on a rotating platform, enables alternating testing of two sets of transformer oil. While testing the transmittance of one set of transformer oil at operating temperature, the other set of transformer oil is tested at room temperature, significantly shortening the testing cycle and improving batch testing efficiency. At the same time, by combining precise temperature control of the heating component with optical detection, the transmittance of transformer oil under multiple temperature gradients such as room temperature and operating temperature can be compared and tested. This allows for a comprehensive understanding of the impact of temperature changes on the transmittance performance of transformer oil, overcoming the limitations of existing testing methods and further improving the comprehensiveness of new material testing.

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1-13 As shown in the figure, this disclosure proposes a transformer oil transmittance detection device, including a detection base 1, a loading and unloading assembly 3, a detection assembly 4, and a heating assembly 5. A heat insulation cover 6 is fixedly connected to the upper side of the detection base 1, covering the portion above the rotating platform 2. The heat insulation cover 6 has a three-dimensional fan-shaped structure and is located on the same central axis as the rotating platform 2. Opening and closing plates 8 are slidably fitted at the inlet and outlet of the heat insulation cover 6. A first electric cylinder 9 is fixedly installed above the inlet and outlet of the heat insulation cover 6. One end of the telescopic rod of the first electric cylinder 9 is fixedly connected to a connecting landing gear 10. The rod of the landing gear 10 is fixedly connected to the upper side of the opening and closing plate 8. A servo motor 11 is fixedly installed at the bottom of the detection base 1. The output shaft of the servo motor 11 passes through the rotating groove 7 and is fixedly connected to the bottom of the rotating platform 2.

[0021] In some embodiments, the loading and unloading assembly 3 is disposed on the detection base 1. The loading and unloading assembly 3 includes a feeding frame 301 fixedly connected to the upper side of the detection base 1. The feeding frame 301 is divided into two sections, and a loading and unloading plate 302 is fixedly connected at the break between them. A conveyor belt 303 is fixedly installed inside the front section of the feeding frame 301. A first loading electric cylinder 304 is fixedly installed on the upper side of the loading and unloading plate 302. Two oppositely arranged unloading frames 305 are slidably fitted on the rotating table 2. The upper side of the rotating table 2 is opened downward. There are two opposing displacement grooves 306. A second spring 307 is fixedly connected between one side of the feeding frame 305 and the inner wall of its corresponding displacement groove 306. A second feeding electric cylinder 308 is fixedly connected to the upper side of the feeding frame 301. A pusher frame 309 is fixedly connected to the end of the telescopic shaft of the second feeding electric cylinder 308. The two feeding frames 305 are slidably fitted on the inner walls of the two displacement grooves 306 respectively. The gap between the two sections of the feeding frame 305 and the feeding frame 301 is fitted together, and one side of the feeding frame 305 is connected to the end of the first feeding electric cylinder 304. The parts abut against each other. A material-binding frame 310 is slidably fitted on the pusher frame 309. A connecting groove frame 313 is fixedly connected to the outer side of the pusher frame 309. The bottom upright plate of the material-binding frame 310 is slidably fitted on the inner wall of the connecting groove frame 313 and a third spring 314 is fixedly connected between them. A linkage bar 315 is fixedly connected below the bottom upright plate of the material-binding frame 310, passing through the connecting groove frame 313. The material-binding frame 310 is in an open frame state, and a movable plate 311 is slidably fitted on one side. A rotating part is fitted on the movable plate 311. The feed frame 310 is threaded with an adjusting screw 312. A dual-axis electric cylinder 316 is fixedly installed in the groove in the middle of the feed frame 305. Both ends of the dual-axis electric cylinder 316 are fixedly connected with clamping plates 317. A connecting strip 318 is fixedly connected to one side of the inner clamping plate 317. The connecting strip 318 passes through the feed frame 305 and is fixedly connected to a linkage feed frame 319 at one end on its outer side. The two clamping plates 317 are slidably engaged between the two side plates of the feed frame 305. The linkage feed frame 319 cooperates with the linkage strip 315.

[0022] Understandably, during device operation, the front section of the feeding frame 301 in the loading and unloading assembly 3 transports a test container containing transformer oil via the conveyor belt 303. When the container is transported to the break point between the two sections of the feeding frame 301, the rotating table 2 drives the unloading frame 305 on one side above it to slide along the displacement groove 306 with the help of the force of the second spring 307 (the second spring 307 is in a compressed state when the unloading frame 305 is on the rotating table 2), so that the unloading frame 305 is precisely aligned with the break point of the feeding frame 301. When the untested transformer oil test container on the conveyor belt 303 is ready to be loaded, and there is a tested transformer oil test container at the break point of the feeding frame 301, the double-shaft electric cylinder 316 in the unloading frame 305 is activated, driving the clamping plates 317 on both sides to release the limit on the tested container. While the innermost clamping plate 317 moves, it drives the connecting bar 318 to move the container. The linkage frame 319 and the linkage bar 315 of the binding frame 310 cooperate to drive the binding frame 310 to move towards the untested transformer oil testing container on the conveyor belt 303. The container is restrained by the side plates of the binding frame 310. The movable plate 311 can be adjusted in position by adjusting the screw 312 to adapt to different specifications of transformer oil testing containers and ensure the accuracy of visual inspection. Then, the second feeding electric cylinder 308 drives the pusher 309 to slide on the feeding frame 301. The untested transformer oil testing container is pushed to the unloading frame 305 by the binding frame 310. At the same time, the tested transformer oil testing container is pushed to the rear section of the feeding frame 301, completing the synchronous switching of loading and unloading. Finally, the first feeding electric cylinder 304 pushes the unloading frame 305 carrying the untested transformer oil testing container to the rotating table 2, ready to enter the next round of inspection process.

[0023] In some embodiments, the detection assembly 4 is disposed on the rotating table 2. The detection assembly 4 includes two sets of detection frames 401 disposed on the rotating table 2. A light source 402 and a light source detector 403 are respectively fixedly installed on opposite sides of the two upright plates of the two sets of detection frames 401. An abutment post 404 with an arc-shaped bottom is fixedly connected to the bottom of the horizontal plate of the detection frame 401. An annular guide rail 12 is fixedly connected to the bottom wall of the rotating groove 7. Two sets of height protrusions 13 are fixedly connected to the upper side of the annular guide rail 12. An annular groove 14 is opened at the bottom of the rotating table 2. The two sets of height protrusions 13 are respectively disposed on both sides above the annular guide rail 12 in a circumferentially symmetrical arrangement, and the height protrusions 13 are arranged from low to high. The slope is set such that the bottom of the rotating platform 2 has two detection rack slots 406 that communicate with the annular groove 14. A fourth spring 405 is fixedly connected between the upper side of the horizontal plate of the detection rack 401 and the bottom wall of the detection rack slot 406. The abutment post 404 abuts and slides on the annular guide rail 12 and cooperates with two sets of height protrusions 13. The annular guide rail 12 is rotatably engaged with the annular groove 14, and the detection rack 401 is slidably engaged with the inner wall of the detection rack slot 406. The light source 402 and the light source detector 403 on the two sets of detection racks 401 are located above the rotating platform 2. When the feeding frame 305 slides into the displacement groove 306 on the rotating platform 2, it is located between the light source 402 and the light source detector 403.

[0024] It should be noted that when the servo motor 11 at the bottom of the detection base 1 is started, its output shaft drives the rotating table 2 to rotate stably in the rotating groove 7. During the rotation, the bottom end of the detection frame 401 in the detection assembly 4 is an arc-shaped abutment post 404, which slides along the annular guide rail 12 to the height protrusion 13 (the height protrusion 13 is set at a slope from low to high, and the two sets of height protrusions 13 are symmetrical on both sides above the annular guide rail 12). The height protrusion 13 pushes the abutment post 404 to rise, which drives the detection frame 401 to slide upward along the detection frame groove 406, so that the light source 402 (visible light source) and the light source detector 403 on the two upright plates of the detection frame 401 are accurately aligned with the detection container in the feeding frame 305. The light source 402 emits visible light that passes through the transformer oil, and the light source detector 403 receives the light after it has passed through and converts it into an electrical signal, thus completing the visual measurement and detection of the light transmittance of the transformer oil at this temperature.

[0025] In some embodiments, a heating assembly 5 is disposed on a detection base 1. The heating assembly 5 includes a fixed frame 501 fixedly connected to the upper side of the detection base 1 and disposed opposite to the feeding frame 301. A lifting plate 502 is slidably fitted to the inner wall of the fixed frame 501. A heating rod 503 with a temperature sensing probe is fixedly connected to the lower side of the front end of the lifting plate 502. A first spring 504 is fixedly connected between the upper side of the lifting plate 502 and the top wall of the fixed frame 501. A connecting frame 15 is fixedly connected to one side of the feeding frame 305. A first positioning rod 16 is fixedly connected to one side of the connecting frame 15. A first positioning groove 17 penetrating into the rotating groove 7 is opened on one side of the upper and lower feeding plates 302. The outer end of the first positioning rod 16 is arc-shaped and abuts against the inner wall of the rotating groove 7. The first positioning rod 16 cooperates with the first positioning groove 17. The connection between the two feeding frames 305 is... The frame 15 is arranged opposite each other and each of its sides is fixedly connected to a connecting plate 18. Each of the two connecting plates 18 is fixedly connected to a beveled abutment block 19 on one side. A through groove 20 is opened through the center of the rotating table 2 in the diameter direction. The two connecting plates 18 are offset and slidably engaged. The two feeding frames 305 are respectively offset and arranged below them by the beveled abutment blocks 19 connected by the connecting plates 18. The connecting plates 18 and the beveled abutment blocks 19 are slidably engaged on the inner wall of the through groove 20. A second positioning rod 505 is fixedly connected to the bottom of the lifting plate 502. Two second positioning grooves 21 are opened downward on the upper side of the rotating table 2. The bottom end of the second positioning rod 505 passes through the second positioning groove 21 and is located in the through groove 20, abutting against the beveled edge of the beveled abutment block 19. The bottom end of the second positioning rod 505 is arc-shaped and extends into the interior of the rotating groove 7. The two second positioning grooves 21 are arranged opposite each other and connected to the through groove 20.

[0026] It should be noted that when the feeding frame 305 moves to the disconnection point of the feeding frame 301, the first positioning rod 16 on one side of its connecting frame 15 engages in the first positioning groove 17 of the upper and lower material plates 302, achieving precise positioning of the entire rotating table 2 and ensuring the measurement accuracy of subsequent testing; at the same time, when the feeding frame 305 moves, the connecting plate 18 drives the inclined abutment block 19 to slide in the through groove 20, so that the inclined side of the inclined abutment block 19 moves away from the bottom end of the second positioning rod 505 at the bottom of the lifting plate 502. At this time, the lifting plate 502 moves downward under the force of the first spring 504 (when both feeding frames 305 are located on the rotating table 2). When the first spring 504 is in a compressed state, the heating rod 503 on the front side of the lifting plate 502 is inserted into the transformer oil detection container on another feeding frame 305 to heat it. When the temperature reaches the set working temperature, the first feeding electric cylinder 304 on the upper and lower feeding plates 302 pushes the feeding frame 305 back to the rotating table 2. When the feeding frame 305 moves back, it drives the inclined side abutment block 19 to reset. Its inclined side abuts against the second positioning rod 505, pushing the lifting plate 502 to move upward, so that the heating rod 503 moves away from the transformer oil detection container, completing the heating operation and providing conditions for optical detection at different temperatures.

[0027] Working principle: This transformer oil transmittance testing device uses optical detection as its core, employing visible light as the detection medium. It falls under the technical category of testing material properties using optical methods (visible light) and can be widely applied in the field of new material testing. Combining metrology, related standardization, and certification service requirements, it achieves accurate and efficient detection of transformer oil transmittance. Furthermore, it incorporates industrial vision, visual intelligence, and AI vision technologies to enhance the intelligence and standardization of the testing process. Its specific working principle and complete workflow are as follows: The front section of the feeding frame 301 in the loading and unloading assembly 3 conveys a test container containing transformer oil via the conveyor belt 303. When the container is conveyed to the break point between the two sections of the feeding frame 301, the rotating table 2 drives the unloading frame 305 on one side above it to slide along the displacement groove 306 under the force of the second spring 307 (the second spring 307 is in a compressed state when the unloading frame 305 is on the rotating table 2), so that the unloading frame 305 is aligned with the break point of the feeding frame 301. When the transformer oil test container is loaded on the conveyor belt 303, when the feeding frame 301 carrying the tested transformer oil test container is at the break point of the feeding frame 301, the double-shaft electric cylinder 316 drives the clamps 317 on both sides to release the limit on the tested transformer oil test container. At the same time, the innermost clamp 317 moves through the connecting strip 3 18 drives the linkage frame 319 to cooperate with the linkage bar 315 of the binding frame 310, so that the binding frame 310 moves towards the transformer oil detection container on the conveyor belt 303, so that the side plates on both sides of the binding frame 310 bind the transformer oil detection container. The movable plate 311 can be adjusted by adjusting screw 312 to adapt to different transformer oil detection containers. Then, the second feeding electric cylinder 308 drives the pusher 309 to slide on the feeding frame 301, so that the undetected transformer oil detection container is moved to the unloading frame 305 through the binding frame 310. At the same time, the detected transformer oil detection container is pushed to the rear section of the feeding frame 301. Finally, the first feeding electric cylinder 304 pushes the feeding frame 301 carrying the undetected transformer oil detection container to the rotating table 2 for the next round of detection. When the feeding frame 305 moves to the disconnection point of the feeding frame 301, the first positioning rod 16 on one side of its connecting frame 15 is positioned in the first positioning groove 17 of the upper and lower material plates 302 to position the entire rotating table 2. Simultaneously, as the feeding frame 305 moves, the connecting plate 18 drives the inclined abutment block 19 to slide within the through groove 20. The inclined side of the inclined abutment block 19 is away from the bottom end of the second positioning rod 505 at the bottom of the lifting plate 502, causing the lifting plate 502 to move downwards under the force of the first spring 504. (When both feeding frames 305 are located on the rotating table 2, the first spring...) (504 is in a compressed state) This causes the heating rod 503 on the front side of the lifting plate 502 to be inserted into the transformer oil detection container on another feeding frame 301 to heat it. When the temperature is reached, the first feeding electric cylinder 304 on the upper and lower feeding plates 302 pushes the feeding frame 305 to reset and be located on the rotating table 2. When the feeding frame 305 resets and moves, it drives the inclined side abutment block 19 to reset and its inclined side abuts against the second positioning rod 505, causing the lifting plate 502 to move upward, so that the heating rod 503 on the lower side of the lifting plate 502 moves away from the transformer oil detection container, thus realizing the heating operation. After the heating operation is completed, the servo motor 11 at the bottom of the detection base 1 starts, and its output shaft drives the rotating table 2 to rotate stably in the rotating groove 7. During the rotation, the arc-shaped abutment post 404 at the bottom end of the detection frame 401 in the detection assembly 4 slides along the annular guide rail 12 to the height protrusion 13 (the height protrusion 13 is set at a slope from low to high, and the two sets of height protrusions 13 are symmetrical on both sides above the annular guide rail 12). The height protrusion 13 pushes the abutment post 404 to rise, causing the detection frame 401 to slide upward along the detection frame groove 406, so that the light source 402 (visible light) on the two upright plates of the detection frame 401... The light source 402 and the light source detector 403 are precisely aligned with the detection container inside the feeding frame 305. The light source 402 emits visible light that passes through the transformer oil, and the light source detector 403 receives the transmitted light and converts it into an electrical signal to complete the visual measurement and detection of the transmittance of the transformer oil at that temperature. During the stage when the abutment column 404 passes through the height protrusion 13, the start and stop of the servo motor 11 are precisely controlled to enable the light source 402 and the light source detector 403 to perform multi-point data sampling on different positions of the transformer oil in the transformer oil detection container, thereby improving the comprehensiveness and accuracy of the detection data and meeting the relevant standardized detection requirements. In addition, two sets of feeding frames 305 are set on the rotating table 2, which can realize the synchronous alternating detection of two sets of transformer oil: after the first set of transformer oil completes the optical detection at room temperature, it is moved to the heating component 5 for heating at the working temperature. At this time, the second set of transformer oil can be placed on the other set of feeding frames 305. While the second set of transformer oil is being optically detected at room temperature, the first set of transformer oil is being detected for transmittance at the working temperature. This cycle is repeated to improve the detection efficiency.
