Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Example

[0022] Reference Figure 1 - Fig. 9 A fully automatic batch efficient detection device for transformers includes a substrate 3 fixed on an automated migration and lifting device, and also includes a contact component 5 fixed at the lower part of the substrate 3, the contact component 5 performs synchronous lifting and lowering movements with the substrate 3, the contact component 5 is used to contact the high-voltage contact terminal and the low-voltage contact terminal of the transformer body 2, wherein the contact component 5 is used to contact the contact terminal of the transformer body 2, and the contact component 5 is provided with an overvoltage protection mechanism, which protects the contact terminal of the transformer body 2 when the substrate 3 descends to contact the contact terminal of the transformer body 2; a detection system, the detection system is electrically connected to the contact component 5, and the detection system receives the high voltage and low voltage of the transformer body 2 through the contact component 5 for analysis and detection.

[0023] In the above-mentioned fully automatic batch efficient detection device for transformer body 2, after the detection device is started, the automatic migration and lifting device moves the substrate 3 to the preset initial position. According to the model of the transformer body 2 to be detected, the operator inputs or automatically reads the parameters of the transformer body 2 such as the position of the high-voltage and low-voltage terminals, the rated voltage, etc. through the control system. The transformer body 2 is positioned using a sensor or a visual system to identify the position of the transformer body 2 to ensure that the transformer body 2 is accurately moved to the bottom of the substrate 3, or the control system sets the moving distance of the conveyor, and then the automatic migration and lifting device controls the substrate 3 to rotate and align with the transformer body 2 for lifting detection; Specifically, the base plate 3 is adjusted to an appropriate height by a lifting device so that the contact assembly 5 can approach the contact terminal of the transformer body 2. The base plate 3 slowly descends with the contact assembly 5 until the contact assembly 5 contacts the contact terminal of the transformer body 2. During the contact process, the overvoltage protection mechanism on the contact assembly 5, such as an elastic buffer or a deformable material, is activated. If the contact terminal is subjected to excessive pressure, the protection mechanism will absorb or buffer the pressure to prevent the terminal from bending or the porcelain bushing from breaking. Once the contact component 5 is safely in contact with the terminals of the transformer body 2, the detection system obtains the voltage signals of the high-voltage and low-voltage terminals through the contact component 5. The detection system analyzes the received voltage data to check whether the various functional indicators of the transformer body 2 meet the design requirements, including but not limited to the transformation ratio, insulation performance, temperature rise, etc. All detection data are recorded and stored for subsequent analysis and reporting. If any abnormality is detected, such as overvoltage, poor insulation, etc., the control system will immediately feedback to the operator and can automatically take safety measures, such as cutting off the power supply or adjusting the detection parameters. After the detection is completed, the substrate 3 rises, the contact assembly 5 is separated from the contact terminal of the transformer body 2, and the substrate 3 returns to the initial position or moves to the position of the next transformer body 2 to be detected, preparing for the next round of detection.

[0024] In order to realize the assembly line efficient automatic detection of the transformer body 2, further, it also includes a conveyor arranged at the lower part of the substrate 3, and the conveyor belt 1 of the conveyor is used to place the transformer body 2, and to transmit the transformer body 2 to the position of the substrate 3 for automatic detection. In order to realize the contact and electrical conduction with the contact terminal of the transformer body 2, further, the contact component 5 includes an insulating tube 501, and a conductive tube 503 for contacting the contact terminal of the transformer body 2 is fixedly connected inside the insulating tube 501, and a fixed tube 505 is fixedly connected to the upper part of the conductive tube 503, and a guide groove 502 is opened at the lower part of the insulating tube 501. In order to protect the contact terminals of the transformer body 2, a protective space is specifically reserved between the conductive disk 508 and the conductive tube 503, or a limit switch is provided on the upper part of the conductive tube 503. Furthermore, a slide bar 506 is slidably installed at the lower part of the fixed tube 505, and a conductive disk 508 for contacting the head of the contact terminal of the transformer body 2 is fixedly connected to the lower part of the slide bar 506, and the upper part of the conductive disk 508 is slidably installed on the upper part of the conductive tube 503 through a spring 507.

[0025] The transformer body 2 is moved to a preset position below the substrate 3 by the conveyor belt 1 of the conveyor. The transformer body 2 is accurately positioned using a sensor or a visual system to ensure that the contact terminal of the transformer body 2 is aligned with the contact component 5. The contact component 5 consists of an insulating tube 501 and an internal conductive tube 503. The conductive tube 503 is fixed to the substrate 3 by a fixed tube 505. A guide groove 502 is provided at the lower part of the insulating tube 501 to guide the conductive tube 503 to accurately contact the contact terminal of the transformer body 2. A slide bar 506 is slidably installed at the lower part of the fixed tube 505. A conductive disk 508 is fixed at the lower end of the slide bar 506. The conductive disk 508 is connected to the upper part of the conductive tube 503 by a spring 507 to ensure that buffering and protection can be provided when contacting the contact terminal of the transformer body 2.

[0026] When the base plate 3 descends, the conductive tube 503 is aligned with the contact terminal of the transformer body 2 through the guide groove 502. The conductive plate 508 descends with the slide bar 506 and contacts the contact terminal of the transformer body 2. A protective space is left between the conductive plate 508 and the conductive tube 503. When the conductive plate 508 contacts the contact terminal of the transformer body 2, any excessive pressure will be absorbed by this space to prevent the terminal from being damaged.

[0027] In another embodiment, a limit switch is provided on the upper portion of the conductive tube 503. When the conductive disk 508 descends to a certain position, the limit switch is triggered to limit the further descent of the pole plate, thereby protecting the contact terminals of the transformer body 2 from overvoltage.

[0028] The conductive disk 508 is connected to the conductive tube 503 through the spring 507. When the conductive disk 508 contacts the contact terminal of the transformer body 2, the spring 507 provides a buffering effect to further protect the terminal from excessive pressure. After the conductive disk 508 contacts the contact terminal of the transformer body 2, the voltage signals of the high-voltage and low-voltage terminals are read through the conductive tube 503. The detection system analyzes the received voltage data and evaluates the performance indicators of the transformer body 2, such as the transformation ratio, insulation performance, etc.

[0029] Furthermore, the contact assembly 5 can realize an efficient and safe detection process in the pipeline detection of the transformer body 2. The design of the contact assembly 5 not only ensures the precise contact of the contact terminals of the transformer body 2, but also ensures that the contact terminals of the transformer body 2 are not damaged during the detection process through a variety of protection mechanisms, thereby improving the detection efficiency and the service life of the equipment.

[0030] In order to enable the detection system to perform power-on detection on the transformer body 2, further, a conductive seat 504 is fixedly connected to the upper part of the fixed tube 505, an insulating seat 509 is fixedly connected to the upper part of the conductive tube 503, and a wiring seat 511 for connecting to the detection system is fixedly installed on one side of the insulating seat 509, and the wiring seat 511 is electrically connected to the conductive seat 504.

[0031] A conductive seat 504 is fixed on the upper part of the fixed tube 505, and the conductive seat 504 provides an electrical connection point for the transformer body 2 to be energized. The conductive tube 503 is isolated from the external environment by the insulating seat 509 to prevent short circuit or accidental electric shock. A wiring seat 511 is connected to the upper part of the insulating seat 509. The wiring seat 511 is fixed on one side of the insulating seat 509 and is used for electrical connection with the detection system. Through the conductive wire, the wiring seat 511 is electrically connected to the conductive seat 504 to form an electrical circuit.

[0032] The detection system applies a test voltage to the transformer body 2 through the terminal block 511, and the voltage is transmitted to the contact terminal of the transformer body 2 through the conductive tube 503, thereby realizing the power-on detection of the transformer body 2. The detection system reads the voltage signals of the high-voltage and low-voltage terminals, and analyzes the performance indicators of the transformer body 2, such as the transformation ratio, insulation performance, etc.

[0033] The insulating seat 509 ensures safety during the detection process and prevents electrical accidents. The overvoltage protection mechanism protects the contact terminals of the transformer body 2 from overvoltage by leaving a protective space between the conductive disk 508 and the conductive tube 503 or by using a limit switch. The detection system can safely and efficiently perform power-on detection on the transformer body 2 to ensure accuracy and safety during the detection process.

[0034] In order to achieve automatic deviation correction when the contact terminal of the conductive tube 503 and the transformer body 2 are in contact, and then maintain the center alignment, further, an automatic calibration component 7 is provided on the upper part of the insulating seat 509, and a guide seat 6 is connected to the upper part of the automatic calibration component 7. There are three guide seats 6. A bidirectional screw 4 for electric drive is rotatably installed inside the middle guide seat 6, and the opposite threads of the bidirectional screw 4 are screwed to a guide seat 6 on the outside, and the slide plate 8 for rotatably installing the bidirectional screw 4 is slidably installed at the bottom of the base plate 3. In order to adjust the lateral distance between multiple high-voltage conductive tubes 503 and low-voltage conductive tubes 503 according to different specifications of the transformer body 2, further, the guide seat 6 includes a slider 601, and the sliders 601 on both sides are provided with screw holes 602 screwed to the bidirectional screw 4. In order to realize that when the guide groove 502 of the insulating tube 501 contacts the contact terminal of the transformer body 2, the insulating tube 501 can be force-displaced to realize the correction action, further, the automatic calibration component 7 includes an air plate 704, a mounting plate 603 fixed to the lower part of the slider 601 is fixedly connected to the air plate 704, four air plates 704 are provided, each of which has a piston rod 705 slidably installed inside, and the ends of the four piston rods 705 are connected to the same fixed block 703, the lower part of the fixed block 703 is fixedly connected to the base 701, and the mounting seat 510 fixed on the insulating seat 509 is fixedly installed on the lower part of the base 701 through the screw 702. In order to balance the air pressure between the air plates 704, a spring 507 can also be arranged between the air plate 704 and the fixed block 703, and further, the four air plates 704 are evenly arranged outside the fixed block 703 in the circumferential direction, and the four air plates 704 are fixedly connected with arc-shaped air pipes 706 between each two.

[0035] Three guide seats 6 are installed on the upper part of the insulating seat 509, wherein a bidirectional screw rod 4 is rotatably installed inside the middle guide seat 6, and the threads at both ends of the bidirectional screw rod 4 are opposite, and are respectively screwed on the guide seats 6 on the left and right sides. By rotating the bidirectional screw rod 4, the distance between the guide seats 6 on the left and right sides can be adjusted, thereby changing the lateral spacing between the multiple high-voltage conductive tubes 503 and the low-voltage conductive tubes 503 to adapt to the contact terminal layout of the transformer body 2 of different specifications, and the slide plate 8 can be driven to move horizontally by the outside to control the vertical spacing between the high-voltage conductive tube 503 and the low-voltage conductive tube 503; A guide groove 502 is provided at the bottom of the insulating tube 501, and the guide groove 502 is used to guide the contact terminal of the transformer body 2 to be aligned with the internal conductive tube 503. The automatic calibration component 7 is fixed to the lower part of the slider 601 through the mounting plate 603. The slider 601 is located in the guide seat 6, and four gas plates 704 are fixed on each guide seat 6. A piston rod 705 is slidably installed in the gas plate 704, and the piston rod 705 is connected to the same fixed block 703 through the piston rod 705. When the contact terminal of the transformer body 2 contacts the insulating tube 501 through the guide groove 502, if the contact terminal is not aligned with the conductive tube 503, the air pressure in the gas plate 704 will change, driving the piston rod 705 to move. The movement of the piston rod 705 will drive the fixed block 703 and the base 701 to deviate, and then drive the insulating tube 501 to deviate accordingly, thereby realizing the automatic deviation correction action of the contact terminal of the transformer body 2 and ensuring the contact The point terminal is aligned with the center of the conductive tube 503, and four gas plates 704 are evenly arranged outside the fixed block 703 in a circumferential direction. They are connected in pairs through arc-shaped gas tubes 706 to form a closed-loop air pressure system. The balance of air pressure is achieved by the flow of gas in the arc-shaped gas tubes 706. When the air pressure in a certain gas plate 704 changes, the gas is redistributed between other gas plates 704 through the arc-shaped gas tubes 706 to maintain the overall air pressure balance. A spring 507 is set between the gas plate 704 and the fixed block 703 to provide additional buffering to prevent damage to the contact terminal of the transformer body 2 due to excessive pressure or sudden contact. Therefore, not only can the distance between the conductive tubes 503 be adjusted according to the different specifications of the transformer body 2, but also the deviation can be automatically corrected during the contact process to ensure that the contact terminal of the transformer body 2 is accurately aligned with the conductive tube 503 through the guide groove 502, so as to perform safe and accurate electrical detection.

At this time, the base plate 3 is driven downward by the automated migration and lifting equipment; Step 3: The contact assembly 5 is in contact with the substrate 3 and the transformer body 2, and the contact terminals of the transformer body 2 are prevented from being bent by the protective space reserved by the contact assembly 5.

[0037] In the present invention, after the detection device is started, the automatic migration and lifting equipment moves the substrate 3 to a preset initial position. According to the model of the transformer body 2 to be detected, the operator inputs or automatically reads the parameters of the transformer body 2 such as the position of the high-voltage and low-voltage terminals, the rated voltage, etc. through the control system. The transformer body 2 is positioned using a sensor or a visual system to identify the position of the transformer body 2 to ensure that the transformer body 2 is accurately moved to the bottom of the substrate 3, or the control system sets the conveyor movement distance, and then the automatic migration and lifting equipment controls the substrate 3 to rotate and align with the transformer body 2 for lifting detection; specifically, the substrate 3 is adjusted to an appropriate height by the lifting equipment so that the contact component 5 can approach the contact terminal of the transformer body 2, and the substrate 3 slowly descends with the contact component 5 until the contact component 5 is aligned with the transformer body 2. The contact terminals are in contact. During the contact process, the overvoltage protection mechanism on the contact component 5, such as elastic buffer or deformable material, is activated. If the contact terminal is subjected to excessive pressure, the protection mechanism will absorb or buffer the pressure to prevent the terminal from bending or the porcelain bushing from breaking. Once the contact component 5 is safely in contact with the terminal of the transformer body 2, the detection system obtains the voltage signals of the high-voltage and low-voltage terminals through the contact component 5. The detection system analyzes the received voltage data to check whether the various functional indicators of the transformer body 2 meet the design requirements, including but not limited to transformation ratio, insulation performance, temperature rise, etc. All detection data are recorded and stored for subsequent analysis and reporting. If any abnormality such as overvoltage, poor insulation, etc. is detected, the control system will immediately feedback to the operator and can automatically take safety measures.
