Description

Technical Field

[0001] This application belongs to the field of distribution network terminal technology, and more specifically, relates to a device for factory inspection of distribution network terminals. Background Technology

[0002] With the development of smart distribution networks, the scale of distribution networks is further expanding, and the number of distribution network terminals used on the load side is increasing. The power grid system is placing higher demands on the quality of distribution network terminals to ensure their stable and reliable operation after commissioning.

[0003] In existing technologies, factory testing of distribution network terminals typically employs manual testing methods, involving manual wiring and manual observation of local AC inputs and outputs. This technical approach generally suffers from the following problems:

[0004] 1) Current factory inspection requires manual wiring and testing on the backplane of the distribution network terminal board. Taking the commonly used 8-bay centralized substation terminal of the distribution network ring network cabinet as an example, assuming that wiring and testing one bay takes 10 minutes, testing 8 bays would take approximately 80 minutes. This process is time-consuming, inefficient in factory inspection, and seriously affects the requirement for rapid delivery of distribution network terminals.

[0005] 2) Existing factory inspection requires one person to measure and another person to observe and collect data at the distribution network terminal to ensure accuracy, which results in high labor costs and certain errors due to manual observation.

[0006] 3) The existing factory inspection method uses manual wiring for each unit, which is inherently unpredictable. Incorrect wiring may cause short circuits, potentially damaging the distribution network terminal and posing a risk to personal safety. Utility Model Content

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please refer to the following: Figure 1 and Figure 2 The apparatus for factory inspection of distribution network terminals provided in this application embodiment will now be described. This apparatus for factory inspection of distribution network terminals includes a workbench 100, a probe module box 200, and a carrier board 300; a wiring panel 101 is provided on the workbench 100; the probe module box 200 is detachably connected to the workbench 100 and electrically connected to the wiring panel 101; please refer to the following documents. Figure 4 , Figure 5 and Figure 6 The probe module box 200 is provided with multiple strikers 201, and each striker 201 corresponds to a wiring port on the distribution network terminal to be tested. The carrier plate 300 is slidably connected to the workbench 100, and the distribution network terminal to be tested is installed on the carrier plate 300. The carrier plate 300 has a first position and a second position. In the first position, the distribution network terminal to be tested is away from the probe module box 200. In the second position, the distribution network terminal to be tested is aligned with and abuts against the strikers 201 of the probe module box 200.

[0042] The device for factory inspection of distribution network terminals provided in this application embodiment, compared with the prior art, includes a probe module box 200. During testing, the probes of the distribution network terminal to be tested align and abut against the strikers 201 of the probe module box 200, replacing the manual wiring in the prior art. This significantly improves the efficiency of factory inspection and testing, and saves labor costs. The probe module box 200 is detachably connected to the workbench 100, facilitating the functional expansion and upgrade of the probe module box 200. It also facilitates the replacement of the probe module box 200. For different types of distribution network terminals, only the corresponding probe module box 200 needs to be replaced, without the need to redesign the test scheme, thus improving the versatility of the device. The wiring is completed internally in the probe module box 200, eliminating the need for manual wiring. This avoids risks such as inaccurate test results, damage to the distribution network terminal, and personal injury to test personnel caused by incorrect wiring, improving the accuracy and reliability of test results, enhancing the quality of distribution network terminal products, and ensuring the pass rate of incoming inspection.

[0043] It is understandable that the distribution network terminal to be tested can have various product forms, such as 4U full-layer, 4U half-layer, 6U 1 / 3-layer, and other special forms; the probe module box 200 is designed according to the product form of the distribution network terminal to be tested, such as... Figure 4-like Figure 6 As shown in the figure, three different probe module boxes 200 are illustrated. The AC quantity circuit and the input and output circuit are connected in the probe module box 200. The voltage is connected in parallel and the current is connected in series in the probe module box 200. In this way, the voltage and current test can be met at one time.

[0044] In one embodiment of this application, an adapter pin plate is also provided on the workbench 100. The adapter pin plate is used to transfer the wiring of the probe module box 200 to the workbench 100, and to complete the wiring transfer of voltage, current, network port, serial port to the wiring panel 101 inside the workbench 100. The wiring panel 101 can be used to connect a relay protection device, a host computer, and a power supply.

[0045] In one embodiment of this application, please refer to Figure 1 The device also includes a first fixing clamp 400, which is mounted on the worktable 100 and is used to clamp the probe module box 200 onto the worktable 100.

[0046] In this embodiment, the design of the first fixing clamp 400 effectively prevents the probe module box 200 from shifting during the testing process, thereby ensuring the precise connection between the striker 201 and the distribution terminal connector. This robust clamping method not only improves the reliability of the test but also reduces testing errors caused by loose module boxes.

[0047] In one embodiment of this application, a first positioning structure is provided on the workbench 100, and a second positioning structure is provided on the probe module box 200. The first positioning structure and the second positioning structure are connected in cooperation.

[0048] In this embodiment, the coordinated design of the first and second positioning structures ensures accurate positioning of the probe module box 200 on the worktable 100. This positioning method not only simplifies the installation process but also significantly improves the connection stability between the probe module box 200 and the worktable 100. This structural design effectively avoids test deviations caused by inaccurate positioning, further enhancing the ease of operation and testing accuracy of the device.

[0049] Specifically, the first positioning structure can be a positioning post, and the second positioning structure can be a positioning hole. The cooperation between the positioning post and the positioning hole enables the rapid installation and removal of the probe module box 200, while ensuring consistent positioning each time. This design not only improves work efficiency but also reduces errors that may be caused by human operation, thereby further enhancing the accuracy and reliability of factory inspection.

[0050] In one embodiment of this application, please refer to the following: Figures 4 to 6The probe module box 200 is equipped with a handle 202, which is used to pick up the probe module box 200.

[0051] In this embodiment, the handle 202 is designed with ease of operation in mind. Its shape and size have been optimized to suit the usage habits of different users. By setting the handle 202 on the probe module box 200, not only is the portability of the module box improved, but the risk of damage caused by directly gripping the surface of the module box is also reduced.

[0052] Specifically, the handle 202 can be an elongated hole structure on the side of the probe module box 200, or a pull ring structure installed on the side of the probe module box 200. The elongated hole structure can effectively save space while providing sufficient force points during operation, making it convenient for users to quickly pick up and move the probe module box 200. The pull ring structure further enhances the comfort of gripping, especially suitable for scenarios that require frequent handling or long-term operation.

[0053] In one embodiment of this application, please refer to the following: Figure 1 and Figure 2 The device also includes a second fixing clamp 500, which is mounted on the carrier plate 300 and is used to clamp the distribution terminal to be tested onto the carrier plate 300.

[0054] In this embodiment, by providing a second fixing clamp 500, the distribution network terminal to be tested can be firmly fixed on the carrier plate 300, preventing displacement during sliding or testing. This clamping design not only improves the stability of the testing process but also significantly reduces testing errors caused by terminal loosening, thereby further improving the accuracy and reliability of factory inspection. Furthermore, the second fixing clamp 500 adopts an adjustable structure, allowing for flexible adjustment according to distribution network terminals of different sizes and shapes, enhancing the adaptability of the device and meeting diverse testing needs.

[0055] In one embodiment of this application, please refer to Figure 2 The carrier board 300 is provided with multiple limit blocks 600, which enclose an installation space. The distribution terminal to be tested is placed in the installation space and abuts against the limit blocks 600.

[0056] In this embodiment, the design of the limiting block 600 effectively constrains the position of the distribution network terminal to be tested, ensuring its stability on the carrier plate 300. This enclosed installation space not only prevents the terminal from shifting during sliding but also provides additional safety for the testing process. The tight contact between the limiting block 600 and the distribution network terminal further improves the accuracy of the test and avoids test errors caused by equipment shaking or positional deviation.

[0057] In one embodiment of this application, the limiting block 600 includes an elastic element, a pressure block, and a connecting block; the carrier plate 300 is provided with a sliding groove, the elastic element is disposed in the sliding groove, the connecting block is slidably connected to the sliding groove, one end of the connecting block is connected to the pressure block, and the other end of the connecting block abuts against the elastic element.

[0058] In this embodiment, the elastic element provided by the limiting block 600 offers flexible adjustment capabilities, allowing the pressure block to adaptively adjust according to the size and shape of the distribution network terminal to be tested. This design not only enhances the device's compatibility with terminals of different specifications but also ensures that the terminal remains stable throughout the testing process. Through the cooperation of the sliding groove and the connecting block, the limiting block 600 achieves precise position control, further improving the reliability and accuracy of the testing.

[0059] It is understandable that multiple limit blocks 600 can be symmetrically arranged along the length and width directions of the carrier plate 300. For example, in two limit blocks 600 arranged along the length direction of the carrier plate 300, the two pressure blocks are arranged opposite each other. Through the elastic force of the elastic element, the distribution terminal to be tested can be clamped between the two pressure blocks. The same applies to the limit blocks 600 in the width direction.

[0060] In one embodiment of this application, please refer to the following: Figure 2 and Figure 3 The worktable 100 is provided with a slide rail 102, and the carrier plate 300 is provided with a slider 301, which is slidably connected to the slide rail 102.

[0061] In this embodiment, the cooperative design of the slide rail 102 and the slider 301 ensures that the carrier plate 300 slides smoothly on the worktable 100, thereby realizing the precise switching of the distribution network terminal under test between the first position and the second position. This structure not only improves the convenience of operation, but also significantly enhances the stability and reliability of the testing process.

[0062] In one embodiment of this application, please refer to Figure 1 The device also includes a drive unit 700, which is mounted on the worktable 100. The movable end of the drive unit 700 is connected to the carrier plate 300, and the drive unit 700 is used to push the carrier plate 300 to slide.

[0063] In this embodiment, by setting the driving component 700, the movement of the carrier plate 300 can be easily controlled, making the sliding of the carrier plate 300 more stable and controllable, and further improving the reliability and consistency of the factory inspection.

[0064] In one embodiment of this application, please refer to Figure 2The driving component 700 includes a base 701, a connecting seat 702, a guide rod 703, a pull rod 704, and a swing rod 705. The base 701 is mounted on the worktable 100 and has a guide sleeve 711. The connecting seat 702 is mounted on the carrier plate 300. The guide rod 703 is slidably connected to the guide sleeve 711, and the first end of the guide rod 703 is connected to the connecting seat 702. One end of the pull rod 704 is hinged to the base 701, and the other end of the pull rod 704 is the driving end. One end of the swing rod 705 is hinged to the middle of the pull rod 704, and the other end of the pull rod 704 is hinged to the second end of the guide rod 703.

[0065] In this embodiment, the drive component 700 features an ingenious structural design. Through the coordinated operation of the base 701, connecting seat 702, guide rod 703, pull rod 704, and swing rod 705, precise control of the sliding of the carrier plate 300 is achieved. Specifically, when an external force is applied to the drive end of the pull rod 704, the pull rod 704 rotates around the hinge point, driving the swing rod 705 to move, thereby pushing the guide rod 703 to slide within the guide sleeve 711. Since the first end of the guide rod 703 is connected to the connecting seat 702, the sliding of the guide rod 703 is directly transmitted to the connecting seat 702, thereby driving the carrier plate 300 to move smoothly.

[0066] The working process of the device for factory testing of distribution network terminals provided in this application embodiment is as follows:

[0067] First, the distribution network terminal to be tested is fixed in the mounting space on the carrier plate 300. The second fixing clamp 500 and the limiting block 600 work together to ensure the terminal remains stable on the carrier plate 300. Then, the operator can apply external force through the driving end of the driving component 700, causing the pull rod 704 to rotate around the hinge point and drive the swing rod 705 to move, thereby pushing the guide rod 703 to slide within the guide sleeve 711. The sliding of the guide rod 703 is transmitted to the carrier plate 300 through the connecting seat 702, enabling the carrier plate 300 to move smoothly from the first position to the second position. During this process, the cooperation between the slide rail 102 and the slider 301 further ensures the stability of the carrier plate 300's sliding motion.

[0068] When the carrier board 300 reaches the second position, the distribution network terminal to be tested aligns and abuts against the striker 201 of the probe module box 200. At this point, the wiring inside the probe module box 200 is complete, requiring no manual intervention and thus avoiding testing problems caused by wiring errors. The design of the first fixing clamp 400 and the positioning structure ensures the stability and precise positioning of the probe module box 200 on the workbench 100, further improving the reliability of the test. After the test is completed, the operator can reverse the operation of the drive component 700 to move the carrier board 300 back to the first position and remove the tested distribution network terminal. The entire process is efficient, accurate, and safe, significantly improving the efficiency and quality of factory inspection.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
