Description

Technical Field

[0001] This utility model relates to the field of high-pressure resistance testing technology, and specifically discloses a combined high-pressure resistance test bench. Background Technology

[0002] High-voltage withstand testing is a non-destructive testing method designed to verify the quality and electrical safety of products, ensuring their insulation performance meets requirements when exposed to transient high-voltage conditions. This test assesses the insulation withstand strength by applying a continuous high voltage to the product under test for a period of time, and is a crucial step in verifying whether a product can reliably withstand the effects of high-voltage electrical stress. The core test content covers two important indicators: the determination of breakdown voltage, to confirm the maximum voltage that the insulating material or component can withstand; and the monitoring of leakage current, to assess the extent of illegal current leakage under high voltage. This process emphasizes that arcing must be strictly prevented throughout the high-voltage application phase, serving as a key criterion for evaluating the product's insulation integrity and safety.

[0003] A high-voltage withstand testing fixture with patent application number CN214669406U includes a frame, a high-voltage tester, a mounting base, a first movable seat, a first insulating seat, a first linear actuator, a positive conductive plate, a positive conductive spring pin, a second movable seat, a second insulating seat, a second linear actuator, a negative conductive plate, a negative conductive spring pin, and an insulating positioning support. The first and second movable seats are movably and adjustablely mounted on the mounting base along a left-right distance. The first insulating seat is fixedly connected to the output end of the first linear actuator. The positive conductive plate is electrically connected to the positive terminal of the high-voltage tester, and the positive conductive spring pin is conductively connected to the positive conductive plate with an adjustable mounting height. The second insulating seat is fixedly connected to the output end of the second linear actuator. The negative conductive plate is electrically connected to the negative terminal of the high-voltage tester, and the negative conductive spring pin is conductively connected to the negative conductive plate with an adjustable mounting height. The insulating positioning support is fixed on the mounting base. However, this device cannot store and record measurement data, and manual data recording is prone to data loss. Therefore, it is urgent for those skilled in the art to solve the aforementioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a combined high-pressure withstand test bench in order to address the shortcomings of the prior art. This combined high-pressure withstand test bench integrates the control panel and the storage unit together. The output data of the control panel can be stored in the storage unit, which makes it convenient for staff to retrieve the data. The data is stored for a long time and can be reviewed at any time, and it is not easy to lose it.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A combined high-voltage withstand voltage test bench includes a cabinet, a control panel, a storage unit, test interfaces, and a discharge device. The control panel is mounted on the cabinet. The test interfaces include a first test interface and a second test interface, which are installed on the left and right sides of the control panel. Both the first and second test interfaces are electrically connected to a high-voltage power supply. The discharge device includes a first discharge device and a second discharge device. A storage unit is also provided above the control panel. The first and second discharge devices are respectively installed below the first and second test interfaces to quickly release residual high-voltage charge after testing or in emergency situations, ensuring operational safety.

[0007] Furthermore, the control panel is electrically connected to the storage unit, which includes a voltmeter, a timer, and a ohmmeter, used for measuring rated voltage, pressurization time, and insulation resistance, respectively.

[0008] Through electrical connection, the control panel can directly acquire real-time data during the test and automatically record it to the storage unit, eliminating the tedious manual recording steps, reducing human error, and improving data accuracy and testing efficiency. The integration of the voltmeter, timer, and ohmmeter allows the device to simultaneously measure and monitor multiple key parameters: rated voltage measurement ensures that test conditions meet standards; recording the pressurization time is crucial for evaluating the performance stability of materials or equipment under long-term high voltage; insulation resistance measurement directly reflects the quality of the equipment's insulation layer and is a key indicator for evaluating insulation performance. This comprehensive data helps to comprehensively and systematically evaluate the electrical safety and reliability of the tested product. All test data stored in the storage unit can serve as the basis for subsequent analysis, facilitating technicians to quickly review and compare the performance trends of different test batches or the same equipment over time. This is of great value for product quality control, fault diagnosis, and the formulation of preventive maintenance strategies. The integrated design simplifies the operation process; testers only need to complete test settings, execution, and data viewing through the control panel, reducing operational complexity and improving work efficiency.

[0009] Furthermore, the discharger is fixed to the cabinet by bolts, and a grounding wire is provided at the bottom of the discharger.

[0010] Bolt fixing ensures the discharger's firmness and stability during high-voltage testing. Even under significant vibration or external force during discharge, it remains in place, reducing the risk of accidental detachment and ensuring the safety of operators and surrounding equipment. A grounding wire is directly installed at the bottom of the discharger and grounded through the bolt fixing point, providing a low-impedance current release path. This ensures that high-voltage charges are quickly and effectively conducted to the ground, avoiding safety hazards caused by charge accumulation. It also protects the testing equipment and samples from damage. The bolt fixing mechanism facilitates the installation and removal of the discharger. When equipment maintenance or discharger replacement is required, the operation is simple and quick, reducing downtime and improving work efficiency. The standardized bolt fixing method facilitates compatibility with other accessories or different models of dischargers, increasing the equipment's versatility and flexibility, and facilitating future upgrades or modifications.

[0011] Furthermore, an insulating pad is provided on the cabinet, and the insulating pad has an opening through which the grounding wire of the first discharger or the second discharger passes.

[0012] The insulating mat effectively isolates the electrical connection between the cabinet and the ground, preventing accidental current leakage during the operation of the discharger, protecting operators from electric shock, and ensuring a safe experimental environment. The specially designed opening for the grounding wire allows for a more orderly and standardized arrangement of the grounding wire, ensuring that the high-voltage charge generated by the discharger can be quickly and directly conducted to the ground, reducing the risk of residual charge and improving the safety of the testing process. The insulating mat also prevents static electricity buildup from damaging electronic components inside the cabinet, extending the equipment's lifespan, and reducing misoperation or measurement errors caused by static electricity. The clearly defined grounding line layout allows maintenance personnel to quickly locate the grounding wire position during regular inspections or troubleshooting, facilitating maintenance and necessary adjustments, and improving maintenance efficiency.

[0013] Furthermore, the first test interface and the second test interface are provided with multiple sockets, and the control panel is provided between the test interface and the high voltage power supply. The control panel is used to adjust the voltage output of the high voltage power supply and is electrically connected to the test interface.

[0014] The multiple socket design allows for testing of different types of test pieces (DUTs). Regardless of the sample's diameter, shape, or connector type, a suitable interface can be found for testing, enhancing the test bench's adaptability and flexibility. The control panel directly adjusts the high-voltage power supply output, enabling precise setting of test conditions according to the specific requirements of the DUT, achieving customized test solutions and improving test relevance and accuracy. Electrical connection between the control panel and the test interface allows for rapid setting and adjustment of test parameters, shortening test preparation time and improving test efficiency. Simultaneously, it facilitates real-time monitoring of the voltage output status during testing, allowing for timely adjustment of test parameters and optimization of the test process. Because the control panel and test interface are electrically connected, the voltage output data collected during testing can be easily recorded and analyzed, providing detailed data support for subsequent product quality assessment, fault diagnosis, and performance optimization.

[0015] Furthermore, the cabinet is also equipped with handles and cabinet doors, the base is located at the bottom of the cabinet, and the cabinet doors are located on the front of the cabinet.

[0016] The base not only ensures the stability of the test bench but may also include an adjustable height design, allowing for stable placement on uneven ground. Simultaneously, the cabinet's bottom structure facilitates movement using forklifts or other handling equipment, enhancing the equipment's flexibility and convenience in different work environments. The cabinet door's front-facing location allows maintenance personnel to easily open and quickly access internal components for inspection, maintenance, or parts replacement, eliminating the need for complex disassembly and simplifying maintenance operations, saving time and labor costs. The door effectively prevents dust, moisture, and other external factors from entering, protecting the internal precision electronic components and mechanical structures from damage and extending the equipment's lifespan. Furthermore, for high-voltage testing equipment, the enclosed cabinet design helps restrict unauthorized access, increasing operational safety.

[0017] This utility model has the following beneficial effects:

[0018] The control panel is directly connected to a high-voltage power supply, enabling precise adjustment of the output voltage to meet different testing standards and requirements. Meanwhile, the integrated voltmeter, timer, and ohmmeter in the storage unit ensure accurate recording and analysis of test data, providing a reliable basis for product quality assessment.

[0019] By setting the first test interface and the second test interface on the left and right sides of the control panel respectively, the pressure resistance test of two samples can be carried out simultaneously or independently, which greatly improves the testing efficiency. In addition, the multi-interface design also increases the testing flexibility and is suitable for test samples of different sizes and types.

[0020] The first and second dischargers are positioned close to their respective test interfaces, enabling them to immediately release residual high-voltage charges upon completion of testing or in emergency situations. This effectively prevents operators from being injured due to accidental contact and ensures the safety of the experimental environment. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model.

[0028] Reference Figure 1 , Figure 2 and Figure 3 As can be seen, a combined high-voltage withstand voltage test bench includes a cabinet 1 constituting the main body of the device. The bottom of the cabinet 1 is provided with feet 11, the front of the cabinet 1 is provided with handles 12, the top of the cabinet 1 is provided with insulating pads 13, and the cabinet 1 is also provided with a control panel 2. The left side of the control panel 2 is provided with a first test interface 41, the right side of the control panel 2 is provided with a second test interface 42, the first test interface 41 is provided with a first discharger 51, the second test interface 42 is provided with a second discharger 52, and the top of the control panel 2 is provided with a storage unit 3.

[0029] In one embodiment, cabinet 1 is placed in a predetermined position, and the cabinet is adjusted to a level state using feet 11 to ensure that the cabinet is stable and does not wobble. The feet 11 are fixed to the ground using screws. A handle 12 is installed on the front of cabinet 1 and fixed with screws to ensure that the operator can easily open the cabinet door. An insulating pad 13 is placed on top of cabinet 1 at a designated position, ensuring it is flat and secure to provide insulation protection during operation. The control panel 2 is fixed to the predetermined position of cabinet 1 using screws to ensure it is stable and easy to operate. A first test interface 41 and a second test interface 42 are installed on the left and right sides of the control panel 2, respectively, to conduct electrical... Gas connectors ensure that both are correctly connected to the high-voltage power line. The first discharger 51 is installed below the first test interface 41, and the second discharger 52 is installed below the second test interface 42. Ensure that the electrical connection between the discharger and the corresponding test interface is correct, and fix it to the cabinet 1 with bolts to ensure stability. Configure the grounding wire of the discharger and ensure that the grounding wire is correctly connected to the grounding terminal through the reserved opening of the insulating pad 13 to complete the construction of the discharge circuit. Install the storage unit 3 above the control panel 2. The storage unit is used to store test data or preset test programs and other information. Ensure that its electrical connection with the control panel is correct to facilitate data transmission and processing.

[0030] During data recording, control panel 2 communicates with storage unit 3 via an electrical connection. When the test begins, control panel 2 receives a real-time voltage signal from the high-voltage power supply, simultaneously starts its built-in timer, and monitors the leakage current flowing through the sample under test (indirectly reflecting insulation resistance) through test interface 4. The voltmeter, timer, and ohmmeter (which calculates insulation resistance by monitoring leakage current) each collect their respective data. The raw data collected (such as voltage values, timestamps, and resistance values) are temporarily stored in the memory of control panel 2. The microprocessor built into storage unit 3 performs preliminary processing on this data, such as calculating averages, maximums, minimums, or any necessary statistical analysis to extract more meaningful information. The processed data is then transferred to a non-volatile storage medium in storage unit 3, such as a solid-state drive, to ensure data integrity even in the event of a power outage. Storage unit 3 may also organize the data into an easily searchable and analyzable structure according to a preset format or standard, allowing operators to browse, query, and export test reports through storage unit 3.

[0031] Reference Figure 4 An insulating pad 13 is laid on the cabinet 1. A first discharger 51 and a second discharger 52 are installed on the insulating pad 13. The grounding wires of the first discharger 51 and the second discharger 52 pass through the insulating pad 13 and the cabinet 1 to ground.

[0032] In one embodiment, the required test parameters, such as test voltage and pressurization time, are set on the control panel 2. This information is recorded by the storage unit 3. After confirming that the grounding wires of the first discharger 51 and the second discharger 52 are reliably grounded, the control panel 2 is operated to start the pressurization program. The high-voltage power supply begins to output the predetermined voltage to the first test interface 41 and the second test interface 42. At this time, the device under test receives high voltage through the test interface 4 and enters the withstand voltage test state. The voltmeter, timer, and ohmmeter on the control panel 2 monitor the voltage, time, and leakage current (reflecting insulation performance) through the device under test in real time during the test process and transmit the data to the storage unit 3 for recording in real time. After the predetermined test time is reached or an abnormality is detected, the high-voltage power supply is gradually reduced and finally cut off through the control panel 2 to end the withstand voltage test. Once the high-voltage power supply is disconnected, the residual high-voltage charge in the device under test through the grounding wires of the first discharger 51 and the second discharger 52 is quickly released to ensure the safety of personnel and equipment.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
