[0085] Please refer to Figure 2 , the embodiments of the present invention provide an insulating coating high-voltage tester, and its overall structure and function implementation scheme are specifically as follows:

[0086] The insulating coating high-voltage tester is composed of four core modules: a base 1, a carrier device 2, an electrode device 3, and a lifting device 4. Among them, the base 1 serves as the basic support structure of the entire tester, carrying the installation and operation of other functional modules; the carrier device 2 and the lifting device 4 are respectively stably arranged on the base 1 through precise mechanical connection structures, ensuring the relative position accuracy and operation stability between components; the electrode device 3 is installed on the lifting device 4 to form a complete test execution unit.

[0087] The carrier device 2 adopts high-strength and high-rigidity materials and structural designs, with excellent load-bearing capacity and stability. Its function is to provide a stable and reliable placement platform for the device under test 5, ensuring that the device under test 5 will not be displaced or shaken due to external forces during the test, thereby guaranteeing the accuracy of test data. The electrode device 3, as the application end of high-voltage electrical signals, can apply high-voltage electrical signals with specific amplitudes and waveforms to the device under test 5 according to preset test parameters through precise electrical connections and control systems, so as to realize the high-voltage test of the insulating performance of the insulating coating of the device under test 5.

[0088] The lifting device 4, as the key actuator of the testing machine, adopts a high-precision electric or pneumatic drive mode, featuring fast response and precise control. Its function is to drive the electrode device 3 to achieve precise contact and separation with the device under test 5 according to the requirements of the testing process. At the beginning of the test, the lifting device 4 drives the electrode device 3 to descend smoothly, enabling the electrode to form a reliable electrical connection with the device under test 5; after the test is completed, the lifting device 4 drives the electrode device 3 to rise rapidly, achieving safe separation from the device under test 5 and preparing for the next test.

[0089] Regarding the technical advantages and functional characteristics of this embodiment, the following points need to be emphasized:

[0090] Firstly, this embodiment comprehensively introduces the concept of automated operation. Through the precise control of the contact and separation process between the electrode device 3 and the device under test 5 by the lifting device 4, the automation and intelligence of the testing process are realized. This innovative design not only fundamentally eliminates potential safety hazards in the manual operation process, such as electric shock risk, equipment damage risk, etc., but also significantly improves the safety and reliability of the testing process, providing strong guarantees for the personal safety of the testing personnel and the stable operation of the equipment.

[0091] Secondly, the stable design of the carrier device 2 is the key factor to ensure the stability of the testing process. Through precise mechanical structures and material selection, it achieves firm loading and precise positioning of the device under test 5, effectively avoiding interference with the test results caused by factors such as device shaking and displacement. At the same time, the stable design also improves the accuracy and repeatability of the test results, making the test data under different batches and different conditions highly comparable and reliable, providing a solid foundation for subsequent data analysis and quality assessment.

[0092] In addition, the introduction of the automated operation mode also greatly improves the testing efficiency. Under the background of large-scale and high-efficiency testing requirements, this embodiment can quickly and accurately complete a series of testing tasks by virtue of its automated workflow. Compared with the traditional manual testing method, automated operation significantly reduces the number and frequency of manual intervention links, reducing testing errors caused by human factors, such as operator fatigue, inattention, and differences in operation techniques. This not only improves the accuracy and reliability of the test data but also greatly shortens the testing cycle, meeting the urgent needs of modern industrial production for fast and accurate testing.

[0093] Finally, the structural design of this testing machine fully embodies the perfect combination of compactness and rationality. Its overall layout has been carefully planned and optimized, and all components cooperate with each other to achieve the maximization of space utilization and the optimization of function realization. This compact structural design not only facilitates the installation and transportation of the equipment, but also provides a convenient and comfortable operating environment for the operators. At the same time, the reasonable structural design also makes the maintenance and upkeep of the equipment simple and easy, reducing the maintenance cost and downtime of the equipment, and further improving the usage efficiency and economic benefits of the equipment.

[0094] In summary, the high-voltage testing machine for insulating coatings provided by the present invention, with its efficient, safe and reliable characteristics, provides a brand-new solution for the high-voltage testing of the insulating performance of insulating coatings. This solution not only helps to improve the overall level and quality of the testing work, but also promotes the standardization and intelligent development of testing technologies, injecting new vitality into the technological progress and industrial upgrading of related industries.

[0095] Please refer to Figure 1 again, and in combination with the reference Figures 3 - 4 , in an implementation manner of this embodiment, the electrode device 3 is specifically composed of a first base 301, an upper positive electrode block 302 and an upper negative electrode block 303;

[0096] Among them, the first base 301 is stably arranged on the lifting device 4;

[0097] Furthermore, the upper positive electrode block 302 and the upper negative electrode block 303 are installed side by side on the first base 301;

[0098] Specifically, the upper positive electrode block 302 undertakes the important responsibility of applying a high-voltage electrical signal to the upper surface of the positive electrode test area 6 of the device under test 5;

[0099] And the upper negative electrode block 303 is responsible for receiving the high-voltage electrical signal transmitted from the upward-facing side of the negative electrode test area 7 of the device under test 5 to form a complete electrical circuit with the upper positive electrode block 302.

[0100] Please refer to Figures 3 - 4 again, in an implementation manner of this embodiment, the electrode device 3 not only includes the components described above, but also further adds key components such as a mounting block 304, a guide rail mechanism 305 and a spring 306.

[0101] Specifically, the upper positive electrode block 302 and the upper negative electrode block 303 are respectively stably installed on an independent mounting block 304, ensuring the accurate positioning and stability of the electrode blocks.

[0102] Further, the side of the mounting block 304 is slidably connected to the first base 301 through the guide rail mechanism 305. This design enables the mounting block 304 to move flexibly in a specific direction, laying the foundation for subsequent buffering and moving functions.

[0103] Meanwhile, the top of the mounting block 304 forms an elastic abutting relationship with the first base 301 through the spring 306. This structural configuration enables the spring 306 to play its buffering role under specific conditions.

[0104] Specifically, when the upper positive electrode block 302 and the upper negative electrode block 303 are respectively in contact with the device under test 5, the spring 306 can effectively absorb and disperse the impact force generated during the contact process, thereby providing necessary buffering protection for the contact between the electrode block and the device under test 5, and preventing equipment damage or test result distortion caused by excessive impact force.

[0105] In addition, the guide rail mechanism 305 plays a crucial role during the buffering process. It can not only ensure that the upper positive electrode block 302 and the upper negative electrode block 303 can move smoothly and precisely in the vertical direction under the action of the spring 306, but also effectively limit the offset of the electrode block in other directions, thereby ensuring the stability and reliability of the test process.

[0106] Please refer to Figures 3 - 4 again. In an implementation manner of this embodiment, to ensure precise and stable docking between the electrode device 3 and the carrier device 2, a key structure, the alignment guide post 307, is particularly added to the mounting block 304.

[0107] Specifically, the alignment guide post 307 is precisely arranged on the mounting block 304, and its position and size are carefully designed and calculated to ensure perfect fit with the corresponding structure on the subsequent carrier device 2.

[0108] Meanwhile, a corresponding alignment guide hole 8 is also provided on the carrier device 2 to cooperate with the alignment guide post 307. The parameters such as the opening position, hole diameter size, and depth of the alignment guide hole 8 are strictly matched with the alignment guide post 307, aiming to ensure seamless connection and precise positioning during the docking of the two.

[0109] Through the close cooperation between the alignment guide post 307 and the alignment guide hole 8, not only can the docking accuracy and stability between the electrode device 3 and the carrier device 2 be effectively improved, but also the risk of test errors or equipment damage caused by docking deviation can be significantly reduced. At the same time, this design also provides strong support for the subsequent automated test process, making the entire test process more efficient and reliable.

[0110] In a specific implementation provided in this embodiment, to further improve the automation control accuracy and test safety of the electrode device 3, a key component, the distance sensing device, is particularly added to the electrode device 3.

[0111] Specifically, the distance sensing device is precisely installed on the lifting device 4, and its position is carefully selected and adjusted to ensure that it can sense the specific distance changes of the upper positive electrode block 302 and the upper negative electrode block 303 during the descending process in real time and accurately.

[0112] The distance sensing device adopts advanced sensor technology and signal processing algorithms, can monitor the descending distance of the electrode block in real time, and feedback the relevant data to the control system in real time. Through the precise analysis of these data by the control system, it can accurately judge whether the upper positive electrode block 302 and the upper negative electrode block 303 have respectively achieved effective contact with the device under test 5.

[0113] This design not only effectively improves the automation level and control accuracy of the test process, but also greatly enhances the safety of the test process. By monitoring the descending distance of the electrode block in real time, the control system can timely adjust the operating state of the lifting device 4 to avoid damage between the electrode block and the device under test 5 or distortion of the test results caused by excessive descent. At the same time, this design also provides strong support for subsequent fault diagnosis and preventive maintenance, helps to extend the service life of the equipment and reduce the maintenance cost.

[0114] Please refer to Figures 5 - 16 In an implementation of this embodiment, the design of the carrier device 2 fully considers the diverse test requirements of the device under test 5, and its structural composition is fine and its functions are complete. Specifically, the carrier device 2 mainly consists of key components such as the second base 201, the internal positive electrode block 202, the internal negative electrode block 203, the external positive electrode block 204, and the external negative electrode block 205.

[0115] The second base 201, as the basic support structure of the carrier device 2, is stably set on the base 1, providing a stable working platform for the entire carrier device 2.

[0116] The internal positive electrode block 202 and the internal negative electrode block 203 are arranged side by side on the second base 201, and their design fully considers the internal electrode layout of the device under test 5. Specifically, the internal positive electrode block 202 includes a first internal positive electrode part 2021 and a second internal positive electrode part 2022 arranged vertically, while the internal negative electrode block 203 includes a first internal negative electrode part 2031 and a second internal negative electrode part 2032 arranged vertically.

[0117] During the assembly process, the device under test 5 is precisely sleeved on the first internal positive electrode portion 2021 and the first internal negative electrode portion 2031, and the positional relationship between the two is carefully designed to ensure that the first internal positive electrode portion 2021 can achieve precise docking with the inward-facing surface of the positive electrode test area 6 of the device under test 5, and the first internal negative electrode portion 2031 can closely fit with the inward-facing surface of the negative electrode test area 7 of the device under test 5. At the same time, the second internal positive electrode portion 2022 and the second internal negative electrode portion 2032 are respectively arranged corresponding to the downward-facing surfaces of the positive electrode test area 6 and the negative electrode test area 7 of the device under test 5 to achieve comprehensive internal and lower electrode coverage.

[0118] In terms of function realization, the first internal positive electrode portion 2021 is responsible for applying a high-voltage electrical signal to the inward-facing surface of the positive electrode test area 6 of the device under test 5, and the first internal negative electrode portion 2031 is responsible for receiving the high-voltage electrical signal transmitted from the inward-facing surface of the negative electrode test area 7 of the device under test 5 to form a complete electrical circuit with the first internal positive electrode portion 2021. The second internal positive electrode portion 2022 and the second internal negative electrode portion 2032 are respectively responsible for the task of applying a high-voltage electrical signal to the downward-facing surfaces of the positive electrode test area 6 and the negative electrode test area 7 of the device under test 5.

[0119] In addition, to meet the external electrode test requirements of the device under test 5, the carrier device 2 is also specially provided with an external positive electrode block 204 and an external negative electrode block 205. These two are also arranged side by side on the second base 201, where the external positive electrode block 204 is responsible for applying a high-voltage electrical signal to the outward-facing surface of the positive electrode test area 6 of the device under test 5, and the external negative electrode block 205 is responsible for receiving the high-voltage electrical signal transmitted from the outward-facing surface of the negative electrode test area 7 of the device under test 5 to form a complete electrical circuit with the external positive electrode block 204.

[0120] Through the above design, the carrier device 2 realizes the all-round and multi-angle electrode coverage and test function for the device under test 5, providing strong technical support for the performance evaluation and quality inspection of the device under test 5.

[0121] Please refer to again Figures 5 - 7 , and Figures 11 - 12 , in an implementation manner of this embodiment, to further improve the test flexibility and adaptability of the carrier device 2, the carrier device 2 is specially provided with a key component, a displacement mechanism 206.

[0122] Specifically, the external positive electrode block 204 and the external negative electrode block 205 are not directly fixed on the second base 201, but are respectively connected and positioned with the second base 201 through the displacement mechanism 206. This design enables the external positive electrode block 204 and the external negative electrode block 205 to move flexibly according to actual needs during the test.

[0123] As the core component for realizing the movement of the external electrode block, the displacement mechanism 206 is based on advanced driving technology and precise mechanical structure design. During the test, when it is necessary for the external positive electrode block 204 and the external negative electrode block 205 to contact the outer sides of the positive electrode test area 6 and the negative electrode test area 7 of the device under test 5, the displacement mechanism 206 can drive the external positive electrode block 204 and the external negative electrode block 205 to move smoothly along the direction close to the device under test 5 according to the preset movement trajectory and speed until the two achieve close contact.

[0124] Conversely, when the test is over or when it is necessary to replace the device under test 5, the displacement mechanism 206 can also drive the external positive electrode block 204 and the external negative electrode block 205 to move along the direction away from the device under test 5 according to the opposite movement trajectory and speed until the two are completely separated, providing convenience for subsequent test operations or equipment maintenance.

[0125] Through the above design, the displacement mechanism 206 not only effectively improves the test flexibility and adaptability of the carrier device 2, enabling the test process to be flexibly adjusted according to the electrode layout and test requirements of different devices under test 5, but also significantly improves the test efficiency and test accuracy, reducing errors and uncertainties caused by manual operation. At the same time, this design also provides strong support for the subsequent automated test process, making the entire test process more efficient and reliable.

[0126] Please refer to Figures 13 - 16 again. In an implementation manner of this embodiment, to ensure stable and reliable contact between the electrode block and the device under test 5 and effectively improve the signal transmission quality during the test, a key component, conductive silicone 9, is specially added at the key positions where the upper positive electrode block 302, the upper negative electrode block 303, the first internal positive electrode part 2021, the second internal positive electrode part 2022, the first internal negative electrode part 2031, the second internal negative electrode part 2032, the external positive electrode block 204, and the external negative electrode block 205 contact the device under test 5.

[0127] Specifically, the conductive silicone 9 is precisely attached to the contact surfaces of each electrode block and the device under test 5 due to its excellent electrical conductivity and good elastic properties. Its thickness has been carefully designed and optimized, and finally determined to be 0.2 mm. This thickness can not only ensure that the conductive silicone 9 undergoes appropriate deformation when subjected to pressure, thereby filling the tiny gaps between the electrode block and the device under test 5 to achieve close contact; but also avoid signal transmission delay or energy loss caused by excessive thickness.

[0128] By adding the conductive silicone 9, not only the contact stability and reliability between the electrode block and the device under test 5 are effectively improved, and the risk of test errors or equipment failures caused by poor contact is reduced; but also the signal transmission quality during the test is significantly improved, enabling high-voltage electrical signals to be transmitted more efficiently and accurately to the corresponding test areas of the device under test 5, thereby improving the accuracy and reliability of the test.

[0129] At the same time, the conductive silicone 9 also has good wear resistance and corrosion resistance, and can maintain stable electrical conductivity and mechanical properties during long-term use, further extending the service life of the electrode device and the carrier device and reducing the maintenance cost.

[0130] Please refer to Figures 17 - 18 , in an implementation manner of this embodiment, to ensure that the electrode blocks can effectively avoid the risk of short circuit during the test process and maintain good electromagnetic compatibility, the gaps between the electrode blocks are precisely set in this embodiment.

[0131] Specifically, the gap between the upper positive electrode block 302 and the upper negative electrode block 303 is strictly controlled within the range of 1.0 - 1.17 mm. The setting of this gap fully considers the size and shape of the electrode block and the electrical characteristic requirements during the test process. It can not only ensure that the positive and negative electrodes do not short-circuit due to too close a distance during the transmission of high-voltage electrical signals, but also effectively reduce electromagnetic interference and signal attenuation caused by too large a distance between the electrodes.

[0132] Similarly, the gaps between the internal positive electrode block 202 and the internal negative electrode block 203, and between the external positive electrode block 204 and the external negative electrode block 205 are also set to 1.0 - 1.17 mm. This unified gap setting standard not only simplifies the design and manufacturing processes of the electrode device and the carrier device, improves production efficiency and consistency; but also ensures that stable electrical gaps are maintained between the electrode blocks in different test scenarios, thus guaranteeing the accuracy and reliability of the test results.

[0133] Through the above gap setting, the electrode device and the carrier device in this embodiment have shown excellent electrical performance and stability during the testing process. This design not only effectively improves the testing efficiency and accuracy but also provides strong support for the subsequent automated testing process, making the entire testing process more efficient and reliable. At the same time, this design also fully considers the wear and deformation of the electrode blocks during long-term use, ensuring the long-term stability and reliability of the gaps between the electrode blocks.

[0134] Please refer to again Figure 2 , in an implementation manner of this embodiment, to further optimize the testing process and improve the automation level of the equipment, this embodiment particularly adds a key component, the sliding device 10.

[0135] Specifically, the carrier device 2 is not directly fixed on the base 1 but is flexibly connected and positioned with the base 1 through the sliding device 10. This design enables the carrier device 2 to perform precise displacement according to actual needs during the testing process, thereby meeting the position requirements of different testing stages.

[0136] The sliding device 10, as the core component for realizing the displacement of the carrier device 2, is designed based on advanced mechanical transmission technology and precise manufacturing processes. Specifically, the sliding device 10 includes two main parts: a slide rail and a slider. Among them, the slide rail, as the moving track of the carrier device 2, is firmly fixed on the base 1, providing a stable moving path for the carrier device 2; while the slider is fixedly connected to the carrier device 2 and can slide smoothly along the slide rail, thereby driving the carrier device 2 to achieve precise displacement.

[0137] During the testing process, when it is necessary to move the carrier device 2 from the loading position to below the electrode device 3, the sliding device 10 can drive the carrier device 2 to move smoothly and accurately to the specified position according to the preset moving trajectory and speed. Conversely, when the testing is over or when it is necessary to replace the device under test 5, the sliding device 10 can also drive the carrier device 2 to displace back from below the electrode device 3 to the loading position according to the reverse moving trajectory and speed, providing convenience for subsequent testing operations or equipment maintenance.

[0138] Through the above design, the sliding device 10 not only effectively improves the automation level of the testing process, reduces manual intervention and operation errors, but also significantly improves the testing efficiency and accuracy, making the entire testing process more efficient and reliable. At the same time, this design also provides strong support for subsequent intelligent upgrading and expansion, enabling the equipment to better adapt to the changes and developments of future testing requirements.

[0139] Although terms such as lifting device and base are used more frequently in this application, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

The contact and separation between the electrode device and the device under test are precisely controlled through a lifting device, effectively avoiding potential safety hazards caused by manual operation and significantly improving the safety of the testing process. Secondly, the stable design of the carrier device can firmly carry the device under test, ensuring the stability of the testing process, while improving the accuracy and repeatability of the test results. In addition, the automated operation greatly improves the testing efficiency, can meet the testing requirements of large-scale and high efficiency, reduces manual intervention, and reduces testing errors caused by human factors. Finally, the structural design of this tester is compact and reasonable, easy to operate and maintain, providing an efficient, safe and reliable solution for the high-voltage testing of the insulating performance of insulating coatings, and promoting the standardization and intelligent development of testing technologies.
