Description

Technical Field

[0001] The present application relates to the field of tool testing devices, and in particular to a novel insulating tool testing bench. Background Art

[0002] Insulating tools are widely and frequently used in power production activities, playing a vital role in ensuring the personal safety of users. According to the "Procedure for Preventive Testing of Power Safety Tools," insulating tools should be regularly subjected to AC withstand voltage tests to assess their insulation strength. This prevents insulation accidents caused by the use of substandard insulating tools, thereby eliminating safety hazards in power production operations.

[0003] At present, when testing insulating gloves and insulating boots, water is usually used as the pressurized conductor. The surface of insulating gloves and insulating shoes is easily damp, resulting in excessive surface leakage current and even surface discharge, which affects the judgment of the test results. In batch testing, it is also impossible to monitor the leakage current of individual test items in real time, and when breakdown or discharge occurs, it is impossible to correctly locate them. Moreover, the number of tests on insulating gloves and insulating boots at a time is currently 4-6, which is not very efficient. At the same time, when testing different items such as insulating mats, insulating rods, insulating ropes, and live work clothes, different platforms need to be used for testing, which requires more manpower and material resources and is not very efficient.

[0004] For example, the patented multifunctional insulation tool test bench integrates various insulation tools, including insulation mats, insulation rods, insulation ropes, live work clothes, insulation boots, and insulation gloves. This multifunctional test bench, constructed from materials such as insulation columns and aluminum plates, enables the inspection and testing of insulation tools. This test bench can monitor the leakage current of individual test items in real time, enabling rapid identification of unqualified items during batch testing, improving test efficiency and saving manpower and resources.

[0005] Existing insulation tool testing equipment has a limited range of tools that can be tested. The test scene is time-consuming and labor-intensive to set up, occupies a large space, and has complex wiring and cumbersome operation. The boosting part is exposed, the safety factor is low, and there is no data processing and analysis function.

[0006] The battery charge and discharge test process of the DC system in the substation is cumbersome and the test cycle is long. During the test, the circuit needs to be frequently disconnected and connected manually, the discharge and charging parameters need to be manually calculated, and the battery-related data needs to be recorded regularly. The workload of the test personnel is heavy, the test efficiency is low, and the reliability and safety cannot be effectively guaranteed. Summary of the Invention

[0007] In order to improve the testing efficiency and accuracy of insulating tools and instruments while ensuring the personal safety of operators, the present application provides a new insulating tool test bench.

[0008] The new insulating tool test bench provided in this application adopts the following technical solution:

[0009] A new type of insulation tool test bench, including:

[0010] The test bench body includes a test box, a water inlet for medium entry on one side of the bottom of the test box, a drain outlet for medium discharge on the other side, and an insulating grid for supporting insulating tools disposed above the bottom wall of the test box;

[0011] A fixing device, the fixing device comprising a fixing bracket arranged above the insulating grid and perpendicular to the insulating grid, the fixing bracket being arranged parallel to the side wall of the test box and supporting and fixing the insulating tool;

[0012] A pressurizing device, the pressurizing device is arranged above the test bench body, and an insulating column is arranged between the pressurizing device and the test bench, including a voltage transformer, a horizontal rod arranged above the voltage transformer, and a vertical rod arranged below the horizontal rod. The vertical rod is a telescopic rod, and a detection head is provided at the front end of the vertical rod to monitor test parameters such as current, voltage, and temperature;

[0013] A control device, which is arranged on one side of the test box and includes a test medium integrated controller and a data processing memory. The test medium integrated controller filters, adjusts the pH value, neutralizes metal ions and adjusts the temperature of the test medium required during the test. The data processing memory stores and analyzes test records, parameters, data, etc., performs full life cycle management on the same insulating tool, evaluates the status of insulating tools and equipment, calculates the detection cycle, and predicts the scrapping time of the tool; a cleaning and drying device, which includes an ultrasonic generator and a drying fan. The ultrasonic generator is arranged on one side of the test box. The test box has a ventilation hole, and the drying fan is arranged towards the ventilation hole.

[0014] By adopting the above technical solution, when testing insulating tools using the above device, the insulating tool to be tested is first placed on the insulating grid and fixed between fixed brackets to ensure the stability of the test piece. Next, the tool is subjected to high-voltage testing using a pressurizing device, in which a voltage transformer is used in conjunction with a telescopic rod to meet the requirements of different voltage levels. At the same time, the test medium integrated controller precisely controls the medium to achieve the optimal test state, reducing the impact on the test results and ensuring that the test conditions fully comply with the requirements of the regulations. This prevents acidic and alkaline substances, metal ions, impurities, etc. from corroding or damaging the test object during the pressurization process, minimizes the impact of the insulation test on the tool, and ensures a stable test environment. The data processing memory comprehensively stores and analyzes test records, parameters, and data, achieving full life cycle management of the same insulating tool. After the test, the ultrasonic generator and drying fan respectively clean and dry the tool to ensure the cleanliness and dryness of the tool, thereby extending its service life. This test bench integrates testing, control, cleaning, and drying, providing comprehensive testing services for insulating tools and greatly improving testing efficiency.

[0015] Preferably, two voltage transformers are provided, and the two voltage transformers are provided at both ends of the cross bar.

[0016] By adopting the above technical solution, the voltage transformer can change the voltage level, and the voltage transformer is set to two with different ratios, so that the test bench can adapt to the testing of insulation equipment of different voltage levels. Different insulation equipment has different design and manufacturing costs, and the voltage ranges they can withstand are also different. If the same ratio is used for testing, it may cause damage to some low-voltage level equipment. Therefore, it is necessary to select a suitable ratio according to the specific voltage level of the equipment to protect the equipment from damage by excessive voltage. At the same time, the flexibility and applicability of the test are greatly enhanced, and the test efficiency is improved.

[0017] Preferably, there are no less than two fixing brackets, the fixing brackets are slidably connected to the insulating grid, a slide rail is provided above the insulating grid, a slider is provided below the fixing bracket, the slide rail is provided in a direction perpendicular to the side wall of the test box, and a fixing piece is provided on the slider to fix the slider.

[0018] By adopting the above technical solution, the fixed bracket can move freely on the insulating grid through a sliding connection, and the position of the fixed bracket can be flexibly adjusted according to the actual size and shape of the insulating tool to adapt to tools of different specifications. The fixing part on the slider can quickly fix the slider at any position on the slide rail, thereby completing the fixing work of the insulating tool conveniently and quickly.

[0019] Preferably, the slider is detachably connected to the slide rail.

[0020] By adopting the above technical solution, the insulating pad is a thinner item and does not need to be clamped by a fixed bracket during measurement. During the test, the fixed bracket needs to be removed and the slider and the slide rail are set to a detachable connection to facilitate the measurement of the insulating pad.

[0021] Preferably, a plurality of fixing grooves are provided on the upper portion of the cross bar.

[0022] By adopting the above technical solution, the insulating rod, electroscope and grounding wire need to be placed on the cross bar during the insulation test. Multiple fixing grooves are opened on the cross bar, and the tools can be firmly fixed on the cross bar through the grooves, which can ensure that the tools will not slide or shift during the test, greatly improving the accuracy and reliability of the test. At the same time, the groove design makes the fixation of the tools simpler and faster, reduces the difficulty of operation, and improves work efficiency.

[0023] Preferably, the fixing grooves are of different sizes.

[0024] By adopting the above technical solution, users can select the most suitable groove for fixation according to specific tools and test requirements, thereby adapting to tools of different sizes and shapes. At the same time, the number and position of the grooves can be customized according to actual needs. Therefore, this design can well adapt to different types of insulating tools and improve the versatility of the test bench.

[0025] Preferably, it further comprises an insulating partition, which is arranged parallel to the side wall of the test box to divide the interior of the test box into multiple test spaces.

[0026] By adopting the above technical solution, the insulating partition can divide the interior of the test box into multiple independent test spaces, effectively isolating different areas, thereby avoiding the impact of accidents in a single test on other tests and ensuring the safety of the test process. At the same time, by separating multiple test spaces, multiple insulation tools can be tested simultaneously without interfering with each other, thereby greatly improving test efficiency.

[0027] Preferably, the ventilation holes are opened on the front and rear sides of the test box, and the drying fans are arranged on the front and rear opposite sides of the test box.

[0028] By adopting the above technical solution, an effective air circulation path can be formed through the ventilation holes on the front and back sides to help dissipate heat inside the test box. The drying fan accelerates the drying process of the insulating tools, which can shorten the test cycle and improve work efficiency. At the same time, the ventilation on both sides can keep the air inside the test box flowing and dry, providing a more ideal testing environment for insulating tools.

[0029] Preferably, a test terminal is provided at the bottom of the test box, and the test terminal is electrically connected to the data processing memory.

[0030] By adopting the above technical solution, by setting test terminals at the bottom of the test box, the test terminals are directly connected to the data processing memory, which facilitates the real-time and accurate collection of various data during the test process, reduces the intermediate links in data transmission, and can reduce the risk of data loss or damage, making the entire test process more concise and efficient, further improving the efficiency, accuracy and real-time monitoring capabilities of the test.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When testing insulating tools using the above-mentioned device, first, the insulating tool to be tested is placed on the insulating grid and fixed between fixed brackets to ensure the stability of the test piece; then, a high-voltage test is performed on the tool using a pressurizing device, in which a voltage transformer is used in conjunction with a telescopic rod to meet the requirements of different voltage levels; at the same time, the test medium integrated controller precisely controls the medium to achieve the optimal test state, reducing the impact on the test results and ensuring that the test conditions fully comply with the requirements of the regulations, avoiding corrosion or damage to the test object by acidic and alkaline substances, metal ions, impurities, etc. during the pressurization process, minimizing the impact of the insulation test on the tool and ensuring a stable test environment; the data processing memory comprehensively stores and analyzes the test records, parameters, and data, realizing full life cycle management of the same insulating tool; after the test, the ultrasonic generator and drying fan are cleaned and dried respectively to ensure the cleanliness and dryness of the tool, thereby extending its service life. This test bench integrates testing, control, cleaning, and drying, providing a full range of testing services for insulating tools and greatly improving testing efficiency;

[0033] 2. The voltage transformer can change the voltage level. Setting the voltage transformer to two different ratios allows the test bench to adapt to the testing of insulation equipment at different voltage levels. Different insulation equipment has different design and manufacturing costs, and its voltage tolerance range is also different. If the same ratio is used for testing, it may cause damage to some low-voltage equipment. Therefore, it is necessary to select the appropriate ratio according to the specific voltage level of the equipment to protect the equipment from damage caused by excessive voltage. At the same time, it greatly enhances the flexibility and applicability of the test and improves the test efficiency.

The position of the fixing bracket can be flexibly adjusted according to the actual size and shape of the insulating tool to adapt to tools of different specifications. The fixing parts on the slider can quickly fix the slider at any position on the slide rail, thereby completing the fixing work of the insulating tool conveniently and quickly.

[0039] The following is combined with Figure 1-3 This application is described in further detail.

[0040] The embodiment of the present application discloses a new type of insulation tool test bench. Figure 1 The new insulating tool test bench includes a test bench body 1, a fixing device 2, a pressurizing device 3, a control device 4 and a cleaning and drying device 5.

[0041] Reference Figure 1 The test bench body 1 is mainly composed of a test box 11, which is made of high-strength and well-insulating materials, such as insulating plastics or composite materials, to ensure electrical safety during the test. A water inlet 111 is provided on one side of the bottom of the test box 11 for the medium to enter. The water inlet 111 is circular and located at the bottom corner of the test box 11 to facilitate the uniform flow of the medium. A drain outlet 112 is provided on the other side for the medium to discharge. The drain outlet 112 is designed to be rectangular and is located at the other corner of the bottom of the test box 11 to achieve smooth discharge of the medium. The position setting of the water inlet 111 and the drain outlet 112 enables an effective medium circulation to be formed inside the test box 11, thereby simulating the working environment of insulating tools in actual use.

[0042] Reference Figure 1 、 Figure 2 An insulating grid 12 is installed above the bottom wall of the test box 11. This grid 12 is a grid-like structure made of an insulating material, such as insulating plastic or ceramic. It is used to support insulating tools and prevent them from coming into direct contact with the bottom wall of the test box 11. The shape of the insulating grid 12 matches the bottom wall of the test box 11, covering the entire bottom wall area and ensuring uniform support for insulating tools.

[0043] Reference Figure 1 The test box 11 also includes an insulating partition. Specifically, the insulating partition and the insulating grid 12 can be set as one piece. The insulating partition is arranged parallel to the side wall of the test box 11, dividing the interior of the test box 11 into multiple test spaces, effectively isolating different areas, thereby avoiding the impact of accidents in a single test on other tests, ensuring the safety of the test process, and at the same time, by separating multiple test spaces, multiple insulation tools can be tested at the same time without interfering with each other, thereby greatly improving the test efficiency.

[0044] The fixture 2 includes a fixing bracket 21 positioned above the insulating grid 12. Bracket 21 is made of a metal material, such as aluminum alloy or stainless steel, to ensure structural strength and stability. Bracket 21 is positioned perpendicular to the insulating grid 12 and parallel to the sidewalls of the test box 11, supporting and securing insulating tools. Bracket 21 is elongated and extends along the length of the test box 11. Fixing holes or clips are located in appropriate locations to accommodate insulating tools of varying shapes and sizes.

[0045] Specifically, the fixed bracket 21 is slidably connected to the insulating grid 12, and a slide rail is arranged above the insulating grid 12. The slide rail is arranged in a direction perpendicular to the side wall of the test box 11. A slider is arranged below the fixed bracket 21, and a fixing part is arranged on the slider. The fixing part can be set to a structure such as a screw. The fixing part on the slider can quickly fix the slider at any position on the slide rail. The slider and the slide rail are detachably connected. Specifically, the slider can be set to a block that is snapped together. For example, the insulating pad is a thinner item and does not need to be clamped by the fixed bracket 21 during measurement. The fixed bracket 21 needs to be removed during the test, and the slider and the slide rail are set to be detachably connected to facilitate the measurement of the insulating pad.

[0046] The pressurizing device 3 is arranged above the test bench body 1 and is isolated from the test bench by an insulating column 31. The pressurizing device 3 includes a voltage transformer 32, a horizontal bar 33 and a vertical bar 34. Two voltage transformers 32 are provided, which adopt an annular structure and are sleeved on the insulating column 31 to convert high voltage into low voltage for measurement and monitoring. The horizontal bar 33 is horizontally arranged above the voltage transformer 32, adopts a cylindrical structure, is made of insulating material, and has a plurality of fixed grooves 331 of different sizes. The vertical bar 34 is a telescopic rod, the lower end of which is connected to the horizontal bar 33, and the upper end is provided with a detection head 341. The detection head 341 is spherical or conical, made of conductive material, and can monitor test parameters such as current, voltage, and temperature.

[0047] The control device 4 is located on one side of the test box 11 and includes a control box 43, a test medium integrated controller 41 and a data processing memory 42. The test medium integrated controller 41 and the data processing memory 42 are installed in the control box 43. The test medium integrated controller 41 adopts a modular design and has functional modules such as filtration, pH value adjustment, metal ion neutralization and temperature control to ensure the stability and consistency of the medium during the test. The data processing memory 42 adopts a high-performance computer system with functions such as data acquisition, storage, analysis and management, and can realize the full life cycle management of insulating tools. A test terminal 13 is set at the bottom of the test box 11, and the test terminal 13 is electrically connected to the data processing memory 42.

[0048] Reference Figure 1 、 Figure 3 The cleaning and drying device 5 consists of an ultrasonic generator 51 and a drying fan 52. The ultrasonic generator 51 is located on the outer wall of one side of the test box 11 and adopts a flat-plate structure. It can generate high-frequency ultrasonic waves to clean dirt and residue from the surface of insulating tools. The test box 11 has ventilation holes 113 at appropriate locations. The ventilation holes 113 are circular or square and are distributed on the front and back sides of the test box 11. The drying fan 52 is located toward the ventilation holes 113 and adopts a centrifugal or axial flow structure. It can effectively deliver hot air into the test box 11 to dry the cleaned insulating tools.

[0049] During the specific implementation process, the test program is first started and relevant parameters are set through the control device 4. The insulating tool to be tested is then placed on the insulating grid 12 and fixed by the fixing bracket 21. Next, the pressurizing device 3 starts working and provides the required voltage and current conditions to perform performance testing on the insulating tool. At the same time, the test medium enters the test box 11 through the water inlet 111 and is processed by the integrated controller to reach a predetermined state to simulate the changes in conditions in the actual working environment. The insulating tool is subjected to durability testing and other projects to evaluate whether its performance indicators meet the expected requirements or industry standards and specifications. During the test, the detection head 341 will collect and record relevant data such as current value, voltage value, temperature value and other key information in real time for subsequent analysis and processing. After completing all test items, the control device 4 will automatically shut down the relevant equipment and system and save all test data and result reports for user query and export. If necessary, the insulating tool after the test can be further cleaned to remove dirt and residue attached to the surface and dried to restore it to its original state for the next use or storage management. In addition, during the entire test process, the test site can be monitored and managed in real time through monitoring equipment to ensure the safety and reliability of the test process.

[0050] The implementation principle of a new type of insulating tool test bench in the embodiment of the present application is as follows: when the insulating tool is tested by the above-mentioned device, first, the insulating tool to be tested is placed on the insulating grid 12 and fixed between the fixed brackets 21 to ensure the stability of the tested piece; then, the tool is subjected to a high-voltage test by the pressurizing device 3, wherein the voltage transformer 32 is used in conjunction with the telescopic rod to meet the requirements of different voltage levels; at the same time, the test medium integrated controller 41 accurately controls the medium to achieve the optimal test state, reduce the impact on the test results, ensure that the test conditions fully comply with the requirements of the regulations, and avoid acidic and alkaline substances. , metal ions, impurities, etc. that cause corrosion or damage to the test object during the pressurization process, minimize the impact of the insulation test on the tools, ensure the stability of the test environment, and the data processing memory 42 comprehensively stores and analyzes the test records, parameters, and data, realizing the full life cycle management of the same insulating tool; after the test, the ultrasonic generator 51 and the drying fan 52 are cleaned and dried respectively to ensure the cleanliness and dryness of the tools, thereby extending their service life.
