[0069] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0070] This application provides a simulator, see Figure 1 , Figure 1 FIG. 1 is one of the structural diagrams of the simulator provided in the exemplary embodiment of the present disclosure. The simulator includes a base 10, two electrode bases 20 and two electrode assemblies.

[0071] The base 10 is provided with a testing station, and the testing station is used to place the object to be tested.

[0072] It should be noted that, in one embodiment, the object to be tested can be placed directly on the testing station. In other embodiments, the object to be tested can be placed on other components by placing other components on the testing station. Specifically, this application does not limit this. In addition, the object to be tested is an insulating material.

[0073] The two electrode holders 20 are respectively arranged on both sides of the test station along the first direction. At least one of the two electrode holders 20 is movably mounted on the base 10 so that the two electrode holders 20 are suitable for approaching or moving away from each other.

[0074] It should be noted that the shapes of the two electrode holders 20 can be set as needed, and this application does not limit this. In addition, one electrode holder 20 can be movably mounted on the base 10, or both electrode holders 20 can be movably mounted on the base 10. Specifically, this application does not limit this.

[0075] The two electrode assemblies are arranged corresponding to the two electrode holders 20, and each electrode assembly includes an electrode rod 31 and a CTI electrode 32. The two electrode holders 20 enable the two electrode rods 31 or the two CTI electrodes 32 to be arranged corresponding to the object to be tested.

[0076] It should be noted that there are many ways to set the two electrode rods 31 or the two CTI electrodes 32 corresponding to the object to be tested. For example, in one embodiment, the two electrode rods 31 can be in contact with the object to be tested. In another embodiment, the two electrode rods 31 are spaced apart and arranged adjacent to the object to be tested. In other embodiments, the two CTI electrodes 32 can be spaced apart and arranged adjacent to the object to be tested. Specifically, the present application does not limit the specific manner in which the two electrode holders 20 can enable the two electrode rods 31 or the two CTI electrodes 32 to be set corresponding to the object to be tested.

[0077] In the simulator of the embodiment of the present application, at least one of the two electrode holders 20 in the simulator is movably installed, which means that they can be moved closer to or farther away from each other according to the test requirements, so that the simulator can adapt to objects to be tested of different sizes and shapes, as well as different test requirements. Each electrode holder 20 is equipped with an electrode rod 31 and a CTI electrode 32, and these two electrodes are used for different test tasks. The electrode rod 31 is suitable for voltage breakdown test and electrical arc verification, while the CTI electrode 32 is specifically used for CTI testing. This design enables the system to easily switch electrodes under different test conditions, thereby improving the versatility of the simulator and making it easy to operate. Since the simulator integrates multiple test functions, there is no need to switch between different test equipment, which saves test time and cost. In addition, due to the flexible configuration of the electrode holder 20 and the electrode assembly, the simulator can quickly adapt to different test requirements, further improving test efficiency.

[0078] The electrode rod 31 and the CTI electrode 32 are suitable for different test scenarios. The electrode rod 31 is usually used for voltage breakdown test and electrical arc verification, while the CTI electrode 32 is specifically used for CTI (Comparative Tracking Index) test. Figure 1 and Figure 3In some embodiments, the electrode rods 31 and CTI electrodes 32 are installed alternately in corresponding electrode holders 20. This allows the simulator to quickly switch electrode types based on specific testing requirements without having to replace the entire electrode holder 20 or system, thereby increasing testing flexibility. This selective installation design makes it easier for testers to prepare and execute tests. They simply select the appropriate electrode based on their needs and install it in the electrode holder 20. This design simplifies the testing process, reducing test preparation time and labor costs. Because the electrode rods 31 and CTI electrodes 32 can be installed alternately, the same set of electrode holders 20 can be used for multiple testing tasks, eliminating the need to purchase multiple sets of electrode holders 20 for different testing tasks and improving equipment utilization. In traditional testing systems, each test task may require dedicated electrodes and equipment, which can cause some equipment to remain idle when not performing a specific test task. This selective installation design allows the same set of equipment to be used for multiple testing tasks, reducing equipment idle time. Because the electrode rods 31 and CTI electrodes 32 can be installed alternately, users do not need to purchase dedicated electrodes and equipment for each test task. This reduces purchase costs, allowing users to gain more comprehensive testing capabilities at a lower cost. The selective installation design makes electrode maintenance and replacement simpler and more convenient. Users only need to replace or maintain the corresponding electrode as needed, without having to perform complex maintenance operations on the entire electrode holder 20 or system. This reduces maintenance costs and improves system reliability and stability.

[0079] In other embodiments, the electrode holder 20 may include a holder and a rotating portion rotatably connected to the holder. At least one of the two electrode holders 20 may have a holder movably mounted on the base 10, and the electrode rods 31 and the CTI electrodes 32 may be mounted on the rotating portion. The rotating portion may be rotated so that the two electrode rods 31 correspond to the object to be tested, or the two CTI electrodes 32 correspond to the object to be tested. Specifically, this application does not limit the specific manner in which the two electrode holders 20 can be arranged so that the two electrode rods 31 or the two CTI electrodes 32 correspond to the object to be tested.

[0080] Reference Figure 1 and Figure 2 , Figure 2 yes Figure 1 As shown in the partial enlarged schematic diagram at point A, in some embodiments, an electrode rod 31 is provided on the electrode holder 20, and the electrode rod 31 is used to perform a voltage breakdown test or electrical arc verification on the test object. In this way, the versatility of the electrode rod 31 is improved, and the simulator can perform a voltage breakdown test or electrical arc verification, thereby improving the versatility of the simulator.

[0081] It should be noted that the voltage breakdown test is used to measure the maximum voltage that the object to be tested can withstand without causing breakdown or damage. It involves applying a gradually increasing alternating or direct current voltage to the object to be tested until the object to be tested fails. This test is very important for ensuring the safe operation of electrical equipment. The electrode rod 31 is planar for contacting the object to be tested. In this way, the electrode rod 31 acts on the object to be tested to provide a uniform electric field distribution. The electrical arc initiation test is mainly to determine the ability of the object to be tested to generate arc discharge under high voltage. By gradually increasing the voltage applied between the two electrode rods 31 until an arc phenomenon occurs on the surface of the object to be tested, the arc initiation voltage of the material can be determined. This process helps to understand the ability of the object to be tested to resist arc formation. Usually, the end of the electrode rod 31 facing the object to be tested exists in the form of a tip because the tip can concentrate the electric field and is more likely to initiate an arc.

[0082] Referring to Figure 2 , the electrode rod 31 includes a connecting section 311 and an abutting section 312 connected in sequence along its length direction. One end of the connecting section 311背离抵接段312 is used for external connection to equipment. Along the direction away from the connecting section 311, the cross-sectional area of the abutting section 312 is set to decrease. And in the direction away from the connecting section 311, the cross-sectional area of the connecting section 311 is S1, and the cross-sectional area of the abutting section 312 is S2, where 0 < S2 ≤ S1. In this way, the electrode rod 31 has a tip, and the head of the tip is planar. The electrode rod 31 can be used not only for the voltage breakdown test but also for the electrical arc initiation verification, improving the versatility of the electrode rod 31.

[0083] It should be noted that for the voltage breakdown test and the electrical arc initiation verification, the electrode rod 31 uses a copper rod with a length of 100 mm and a diameter of the connecting section 311 not less than 6 mm. Of course, in other embodiments, the material of the electrode rod 31 can also include stainless steel or silver, etc. And the length and diameter of the electrode rod 31 can be selected according to needs. This application does not limit this. In addition, the diameter of the end face of the abutting section 312背离连接段311 can be 3 mm.

[0084] Referring to Figure 3 and Figure 4 , Figure 3 is the second structural schematic diagram of the simulator provided in the exemplary embodiment of the present disclosure. Figure 4 is Figure 3 the partial enlarged schematic diagram at B shown. In some embodiments, a CTI electrode 32 is provided on the electrode base 20. The CTI electrode 32 is used to perform a CTI test on the object to be tested. In this way, the simulator can perform a CTI test, improving the versatility of the CTI test.

[0085] Under the combined action of an electric field and an electrolyte, a conductive path gradually forms on the surface of a solid insulating material. This process is called tracking. Tracking may cause creepage, breakdown short circuits, and fire risks in insulating materials. The CTI electrode 32 is primarily used to determine the tracking resistance index and comparative tracking index of solid insulating materials, and is an important safety parameter in general electrical inspection items. Through testing, it is possible to simulate the actual use of electrical products and determine whether conductive substances deposited on the surface of non-metallic materials by charged parts of different polarities will cause material creepage, breakdown short circuits, and fire hazards, thereby evaluating the tolerance of non-metallic materials to the combined action of the above-mentioned electric field and contaminated electrolyte.

[0086] The CTI electrode 32 is a standard CTI test electrode with a thickness of 2 mm and a width of 5 mm. The angle between the two electrodes is 60°. The CTI electrode 32 is mounted on the electrode holder 20 and a weight can be applied to the electrode to achieve an electrode pressure of 1 N. Because the technology for the CTI electrode 32 has been tested, the specific structure of the CTI electrode 32 is not described in detail in this application.

[0087] It should be noted that the electrode rods 31 and CTI electrodes 32 are selectively installed in corresponding electrode holders 20, allowing the simulator to have multiple operating states, including a voltage breakdown test state, an electrical arc verification state, and a CTI test state. In the voltage breakdown test state, the two electrode rods 31 are suitable for clamping the test object in preparation for the subsequent voltage breakdown test. In the electrical arc verification state, the two electrode rods 31 are spaced apart and adjacent to the test object in preparation for the subsequent electrical arc verification. In the CTI test state, the two CTI electrodes 32 are spaced apart and adjacent to the test object in preparation for the subsequent CTI test.

[0088] There are many ways to install the electrode rod 31 and the CTI electrode 32 on the electrode holder 20, for example, Figure 2 and Figure 4In some embodiments, the electrode holder 20 is provided with a mounting hole 21, into which one of the electrode rod 31 and the CTI electrode 32 is adapted to be inserted. This allows the electrode rod 31 or the CTI electrode 32 to be directly inserted into the mounting hole 21 of the electrode holder 20 without the need for complex fixing or connection steps. This design greatly simplifies the installation process, reducing the difficulty and time required. Similarly, because the electrode rod 31 and the CTI electrode 32 are plug-in type, the removal process is also very simple. Testers can easily remove the electrode rod 31 and the CTI electrode 32 from the mounting hole 21 for replacement or maintenance. The electrode rod 31 and the CTI electrode 32 are each suitable for different testing scenarios. Through the plug-in design, testers can easily change the electrode type according to test requirements without having to replace the entire electrode holder 20 or system. When the electrode rod 31 and the CTI electrode 32 need to be replaced due to long-term use or wear, the plug-in design makes the replacement process simpler and faster. This helps to extend the overall service life of the simulator while reducing replacement costs.

[0089] There are many ways to achieve the installation of the electrode rod 31 and the CTI electrode 32 on the electrode holder 20. For example, in some embodiments, the electrode rod 31 and the CTI electrode 32 can also be fixed to the electrode holder 20 by a snap-fit structure. In another embodiment, the electrode rod 31 and the CTI electrode 32 can also be fixed to the electrode holder 20 by a threaded structure. Specifically, the method of installing the electrode rod 31 and the CTI electrode 32 on the electrode holder 20 can be selected as needed, and this application does not limit this.

[0090] Reference Figure 2 and Figure 4In some embodiments, a first threaded hole is provided through the side wall of the mounting hole 21, and the simulator further includes a first screw 41. The threaded section of the first screw 41 is threadedly connected to the first threaded hole, and the first screw 41 is pressed against one of the electrode rod 31 and the CTI electrode 32. In this way, the electrode rod 31 or the CTI electrode 32 inserted into the mounting hole 21 can be firmly fixed to the electrode holder 20, preventing the electrode rod 31 or the CTI electrode 32 from falling off during the test, thereby ensuring the accuracy and reliability of the test. During the tightening process, the first screw 41 can evenly distribute pressure on the contact surface of the electrode rod 31 or the CTI electrode 32, thereby ensuring close contact between the electrode and the electrode holder 20. Close contact helps to improve the electrical conductivity and thermal conductivity between the electrode and the electrode holder 20, reduce contact resistance and heat loss, and thus improve the accuracy and efficiency of the test. When the electrode rod 31 or CTI electrode 32 needs to be replaced due to long-term use or wear, the tester can easily unscrew the first screw 41, remove the electrode rod 31 or CTI electrode 32 from the mounting hole 21, and replace it with a new electrode rod 31 or CTI electrode 32. This design simplifies the process of replacing the electrode rod 31 or CTI electrode 32 and reduces maintenance costs.

[0091] Reference Figure 2 In one embodiment, the simulator further includes a support portion 50 and a bearing seat 60. The support portion 50 is provided at the test station and extends along the direction of gravity. One end of the support portion 50 is connected to the base 10. The bearing seat 60 is movably connected to the support portion 50 so that the distance between the bearing seat 60 and the base 10 along the direction of gravity is adjustable. The bearing seat 60 is used for placing the object to be tested. In this way, since the position of the bearing seat 60 is adjustable along the direction of gravity, the position of the object to be tested placed on the bearing seat 60 is adjustable, which helps to expand the application range of the simulator and make it applicable to more test scenarios and the measurement of objects to be tested of different types and sizes. The movable connection between the bearing seat 60 and the support portion 50 allows the tester to easily adjust the position and height of the object to be tested, thereby improving the accuracy and efficiency of the test.

[0092] It should be noted that the specific structure of the support portion 50 can be set as needed. Figure 2 and Figure 4In some embodiments, the support portion 50 includes two support rods 51 spaced apart along a second direction. The two support rods 51 extend along the direction of gravity. The second direction intersects with the first direction and the direction of gravity. The support seat 60 is provided with two through-holes along the second direction. The two through-holes penetrate the support seat 60 along the direction of gravity. The two support rods 51 are inserted into the through-holes. The side walls of the through-holes are penetrated by second threaded holes. The second threaded holes are internally threaded with second screw members 42. The second screw members 42 abut against the support rods 51. In this way, the position of the support seat 60 on the support rods 51 can be easily adjusted by rotating the second screw members 42. This adjustment method is not only accurate, but also convenient and fast, and can meet the position requirements in different test scenarios. The insertion and fit between the support seat 60 and the support rods 51 and the fixing effect of the second screw members 42 enable the support seat 60 to maintain a stable position during the test. This stability helps to ensure the accuracy and consistency of the test results.

[0093] Reference Figures 3 to 6 , Figure 5 yes Figure 3 The main view of the simulator, Figure 6 yes Figure 3 The right side view of the simulator is shown, Figure 7 yes Figure 3 The top view of the simulator is shown. In some embodiments, the simulator also includes a dripping pot 70, which is mounted on the base 10 and arranged corresponding to the test station. The dripping pot 70 is used to drip liquid onto the object to be tested. In this way, the CTI test requires dripping a specified volume of contaminated liquid (such as 0.1% ammonium chloride solution) between the specified CTI electrodes 32 at a fixed time and height to evaluate the tolerance of the surface of the solid insulating material under the combined action of the electric field and the contaminant medium. The design of the dripping pot 70 just meets this requirement. It can stably and continuously drip a specified amount of contaminated liquid onto the object to be tested, ensuring the accuracy and reliability of the test. The dripping pot 70 has a stable dripping speed, which can ensure that the contaminated liquid is dripped onto the object to be tested at a constant speed within the specified test time. This helps to reduce uncertainty in the test process and improve the repeatability of the test.

[0094] It should be noted that the dripping pot 70 is usually equipped with a precise dripping control system to ensure that the volume of the dripping drops is consistent each time and meets the standard requirements of the CTI test. This helps to improve the accuracy of the test results.

[0095] Reference Figure 4 and Figure 6In some embodiments, the simulator further includes an adjustment seat 80, which is movably connected to the base 10 along the direction of gravity, so that the adjustment seat 80 along the direction of gravity is suitable for moving closer to or farther away from the test station. The adjustment seat 80 is provided for the installation of the drip pot 70. In this way, since the height of the adjustment seat 80 is adjustable, the simulator can easily adapt to objects to be tested of different sizes without replacing or adjusting other components, which improves the applicability and flexibility of the simulator. By adjusting the height of the adjustment seat 80, it is possible to ensure that the dripping port of the drip pot 70 maintains an appropriate distance from the surface of the object to be tested, thereby improving the accuracy of the test. The height adjustability of the adjustment seat 80 helps to reduce errors caused by inaccurate dripping positions, which helps to obtain more reliable test results.

[0096] Reference Figure 1 、 Figure 3 and Figure 5 In some embodiments, the simulator further includes a driving component, which is mounted on the base 10. The driving component is used to drive at least one of the two electrode holders 20 to move. In this way, the driving component can drive the electrode holder 20 to move, which means that the position and distance of the two electrode holders 20 can be flexibly adjusted according to different test requirements and the characteristics of the object to be tested. This flexibility enables the simulator to adapt to a wider variety of test scenarios and objects, thereby expanding the application range of the simulator. The automated control function of the driving component can simplify the test operation process, reduce the operating time and labor intensity of the test personnel. At the same time, the rapid response and precise control of the driving component also help to improve the test efficiency and shorten the test cycle. Since the driving component can drive the electrode holder 20 to move, it can easily adapt to objects to be tested of different sizes. This adaptability allows the simulator to perform tests of different sizes without replacing or adjusting other components, thereby improving the flexibility and applicability of the simulator.

[0097] Reference Figure 3In one embodiment, the drive assembly includes a drive motor 91 and a transmission assembly 92. The drive motor 91 is mounted on the base 10 and has a drive shaft extending in a first direction. The transmission assembly 92 is connected to the drive shaft and at least one electrode holder 20. The transmission assembly 92 is configured to convert the rotation of the drive shaft into movement of the at least one electrode holder 20 in the first direction. In this way, the drive motor 91 can precisely control the rotation of the drive shaft, including its angle, speed, and acceleration. This precise control enables highly accurate movement of the electrode holder 20, thereby meeting the simulator's requirements for precise positional control of the electrode rod 31 and CTI electrode 32. The transmission assembly 92 converts the rotation of the drive shaft into movement of the electrode holder 20, and its design generally takes into account transmission stability and reliability. Therefore, under the precise control of the drive motor 91, the movement of the electrode holder 20 can remain stable and consistent, reducing test errors caused by transmission errors. The drive motor 91 has a relatively fast response speed and can quickly adjust the rotation state of the drive shaft, thereby achieving a rapid response to the movement of the electrode holder 20. This helps improve test efficiency and shorten test cycles. The design of the drive motor 91 and the transmission assembly 92 allows the position of the electrode holder 20 to be flexibly adjusted according to different test requirements. This flexibility enables the simulator to adapt to a wider variety of test scenarios and objects, thereby expanding the application range of the system.

[0098] It should be noted that the specific type of the drive motor 91 can be selected as needed. For example, the drive motor 91 may include a brushless DC motor, a brushed DC motor, an asynchronous motor, a stepper motor, or a servo motor. Specifically, in an embodiment of the present application, the drive motor 91 includes a synchronous motor. As such, a synchronous motor is generally more efficient than a traditional asynchronous motor because it does not require additional current to generate torque, reducing energy loss. The speed of a synchronous motor is very stable. The structure of a synchronous motor is relatively simple, without a complex gearbox and transmission mechanism, which makes its manufacturing and maintenance costs relatively low.

[0099] In other embodiments, the drive assembly may further include a cylinder, an electric push rod, or a linear motor, etc. Specifically, the specific type of the drive assembly can be selected as needed, and this application does not limit this.

[0100] Reference Figure 2 、 Figure 5 and Figure 7 , Figure 7 yes Figure 3The top view of the simulator shown in FIG. 1 shows an embodiment of the present invention. The transmission assembly 92 includes a screw 921, a nut 922, and a guide structure 923. The screw 921 extends in a first direction, one end of the screw 921 is connected to the drive shaft, the nut 922 is sleeved on the screw 921, and is threadedly connected to the screw 921. The nut 922 is connected to the electrode holder 20. The guide structure 923 is mounted on the base 10. The guide structure 923 is used to move the nut 922 in the first direction. In this way, the threaded connection between the screw 921 and the nut 922 can achieve precise transmission. Through the precise control of the drive motor 91, it can be ensured that the distance and speed of the nut 922 moving along the screw 921 meet the test requirements, thereby achieving precise control of the position of the electrode holder 20. The guide structure 923 provides a stable movement path for the nut 922, preventing the nut 922 from deflecting or shaking during movement, which further improves the accuracy of the position control of the electrode holder 20. The threaded connection between the screw 921 and the nut 922 has a high transmission efficiency and can effectively transmit the power of the drive motor 91 to the electrode holder 20, which helps to reduce energy loss and improve the overall efficiency of the simulator. Since the threaded connection between the screw 921 and the nut 922 is self-locking, the nut 922 will not move on its own even in the absence of external force. This ensures the stability of the electrode holder 20 in a stationary state. The screw 921, nut 922 and guide structure 923 are generally designed to be a compact structure to save space and reduce the overall weight of the simulator. The structure of the screw 921 nut 922 transmission system is relatively simple and easy to disassemble and clean. At the same time, since the threaded connection between the nut 922 and the screw 921 is self-cleaning, it can reduce the problems of wear and clogging.

[0101] In addition, the thread length of the screw rod 921 can be set as needed, for example, the thread length of the screw rod 921 is 450 mm, and it only needs to ensure that the two electrode rods 31 can contact each other during the movement of the electrode holder 20. Specifically, this application does not limit this.

[0102] It should be noted that the screw rod 921 and nut 922 are typically made of wear-resistant materials, such as stainless steel or alloy steel. This helps extend the service life of the transmission assembly 92 and reduces the frequency of replacement and maintenance. Furthermore, to reduce friction and wear, the screw rod 921 and nut 922 transmission system typically requires reliable lubrication. For example, a suitable amount of lubricating oil or grease can be applied between the screw rod 921 and nut 922 to reduce friction and wear.

[0103] In one embodiment, when the lead screw 921 rotates one full turn, the distance that the nut 922 travels is L, where 0 mm < L ≤ 4 mm. Thus, the distance that the nut 922 travels is within the range of 0 to 4 mm, such that the error generated when adjusting the position of the electrode holder 20 will also be correspondingly reduced. This helps to reduce the test error caused by the inaccurate position of the electrode holder 20 and improve the reliability of the test results. The distance that the nut 922 travels within the range of 0 to 4 mm helps to reduce the vibration generated when the simulator adjusts the position of the electrode holder 20, which helps to maintain the stability of the simulator and improve the reliability of the test results.

[0104] Referring to Figure 3 , Figure 5 and Figure 7 , in some embodiments, the guiding structure 923 includes a guiding portion 9231 and a mating portion 9232. The guiding portion 9231 is connected to the nut 922. The guiding portion 9231 is provided with a through hole extending along the first direction. The mating portion 9232 extends along the first direction and is inserted into the through hole and connected to the base 10. Thus, the cooperation between the guiding portion 9231 and the mating portion 9232 provides a stable linear movement path for the nut 922. This design ensures that the nut 922 does not deviate from the predetermined trajectory during the movement, thereby improving the stability and accuracy of the transmission. The design of the guiding structure 923 effectively reduces the sway of the nut 922 during the movement. This sway may cause slight changes in the position of the electrode holder 20, which in turn affects the accuracy of the test results. Through the stable support of the guiding structure 923, precise control of the position of the electrode holder 20 can be ensured.

[0105] It should be noted that the number of the guiding structures 923 can be set to one, or two or more. Specifically, the present application does not limit this. In addition, in other embodiments, the guiding structure 923 may further include a guiding groove extending along the first direction and a guiding protrusion adapted to the guiding groove. One of the guiding groove and the guiding protrusion is provided on the base 10, and the other is provided on the nut 922. Through the cooperation and installation of the guiding groove and the guiding protrusion, the nut 922 is enabled to move stably along the first direction.

[0106] Referring to Figure 3 and Figure 4In one embodiment, the simulator further includes a temperature measurement module 110. The temperature measurement module 110 is mounted on the base 10 and is arranged corresponding to the test station. The temperature measurement module 110 is used to monitor the temperature of the object to be tested. Thus, through the temperature measurement module 110, the simulator can obtain the temperature change data of the object to be tested during the test process, which is convenient for the analysis of subsequent test results. In addition, in tests that require temperature control, the temperature measurement module 110 can serve as a feedback link for temperature control. By monitoring the temperature data in real time, the system can adjust the test conditions in time to ensure that the test is carried out within a predetermined temperature range. The temperature measurement module 110 can detect overheating of the object to be tested in a timely manner, thereby avoiding potential fire or explosion risks, which is of great significance for ensuring the safety of test personnel and the integrity of the equipment.

[0107] It should be noted that in the embodiments of the present application, the temperature measurement module 110 can verify the tracking resistance of different insulation materials and identify potential defects in high-voltage insulation materials. Furthermore, the temperature measurement module 110 can be of various types, such as an infrared thermometer, an infrared camera, a thermal imager, or a thermal resistor. The type of temperature measurement module 110 can be selected as needed and is not limited in this application.

[0108] Reference Figure 1 、 Figure 5 and Figure 6 In some embodiments, the simulator further includes a weighing module 120 mounted on the base 10. The weighing module 120 is used to check the weight of the object to be tested. Thus, through the weighing module 120, the simulator can obtain accurate weight data of the object to be tested, providing a basis for subsequent analysis and processing. The introduction of the weighing module 120 reduces test errors caused by inaccurate weight measurement. Based on the weight data provided by the weighing module 120, testers can more accurately adjust test parameters, such as arc power and current, to ensure the accuracy and reliability of the test.

[0109] Reference Figure 1 and Figure 2 In one embodiment, the electrode seat 20 that is movably connected to the simulator and the base 10 is a movable electrode seat 20a. The simulator also includes a displacement testing module 130. The displacement testing module 130 includes a fixed part 131 and a movable part 132. One of the fixed part 131 and the movable part 132 is provided on the base 10, and the other is connected to the movable electrode seat 20a. The fixed part 131 and the movable part 132 cooperate to test the displacement of the movable electrode seat 20a. In this way, through the cooperation of the fixed part 131 and the movable part 132, the simulator can accurately adjust the displacement of the electrode rod 31 or the CTI electrode 32 according to the requirements of different tests, thereby improving the accuracy of the test.

[0110] It should be noted that the types of the fixed portion 131 and the movable portion 132 can be set as needed. Specifically, in the present application, the fixed portion 131 is a ruler, and the movable portion 132 is a pointer.

[0111] Reference Figure 1 、 Figure 3 and Figure 5 In some embodiments, the simulator also includes a control module, which is a user interaction module. The control module includes a controller 141, a display screen 142 and a control button 143, wherein the controller 141 has an AC / DC power supply module, a withstand voltage test module, and an overload protection function, and the controller 141 can monitor current, voltage and temperature, etc.

[0112] In one embodiment, the simulator further includes a protective cover (not shown) disposed on the base 10. The two electrodes and the two electrode assemblies are housed within the protective cover, thereby protecting the two electrodes and the two electrode assemblies and improving test safety. The protective cover is required to be made of a transparent, insulating, and highly heat-resistant material.

[0113] According to the second aspect of the present disclosure, referring to Figure 8 , Figure 8 is a flow chart of a testing method provided in an exemplary embodiment of the present disclosure. The present application provides a testing method based on the above-mentioned simulator, comprising:

[0114] Step S100: Determine the test type, and determine one of the electrode rod 31 and the CTI electrode 32 as a test electrode for testing according to the test type.

[0115] It should be noted that the test type can be set as needed. For example, in one embodiment, the test type may include a voltage breakdown test, an electrical arcing verification, a CTI test, etc. Specifically, this application does not limit this.

[0116] Step S200: obtaining an object to be tested and placing the object to be tested on a testing station;

[0117] Step S300: Control the test electrodes to test the object to be tested.

[0118] In the test method of the embodiment of the present application, the test type is first determined, which is the basis of the entire test process. This step ensures the pertinence and accuracy of the test. By clarifying the test type and selecting the corresponding test electrodes, it can be ensured that the test process meets specific test standards and requirements, thereby obtaining reliable test results. The object to be tested is obtained and placed on the test station. By placing the object to be tested on the test station, it can be ensured that the test process proceeds smoothly, and it also helps to protect the safety of the test equipment and operators. By controlling the test electrodes to test the object to be tested, data and information about its electrical properties can be obtained, and the simulator-based test method can be used to perform multiple tests on the object to be tested.

[0119] The insulation scheme of high-voltage circuits usually faces problems such as insulation failure, voltage breakdown, and over-design. The current high-voltage insulation design is generally designed through experience and standard guidance. With the development of insulating materials and semiconductor devices, the insulation design of new components and insulating materials urgently needs to be verified by insulation verification means. The test method provided in this application can provide an insulation design verification means, which can verify the ability of insulating materials of different types, thicknesses, preparation processes, and structural designs to withstand voltage breakdown, study the impact of discharge and ionization effects on insulation aging damage, identify and prevent potential defects in insulation design, and explore the safety boundaries of insulation design.

[0120] Reference Figure 9 , Figure 9 yes Figure 8 One of the flowcharts of the specific steps of step S30, in some embodiments, the test electrode is an electrode rod 31, and step S300 controls the test electrode to test the object to be tested, including:

[0121] Step S310a: Control the simulator 100 to be in a voltage breakdown test state, and enable the two electrode rods 31 to clamp the object to be tested.

[0122] In this step, the simulator 100 is set to the voltage breakdown test state, which means that the parameters such as the voltage level and test time required for the test have been pre-configured according to the standards of the voltage breakdown test, ensuring the accuracy and reliability of the test environment. Two electrode rods 31 are used to clamp the object to be tested, ensuring the stability and position of the object to be tested during the test. This is one of the key steps in performing a voltage breakdown test, because unstable or moving objects may cause deviations in the test results. When clamping the object to be tested, it is necessary to ensure good contact between the electrode rods 31 and the object to be tested to avoid arcing or sparks during the test, thereby ensuring the safety of the test.

[0123] It should be noted that when the simulator 100 is in the voltage breakdown test state, the two electrode rods 31 are electrically connected to the withstand voltage test equipment. This ensures electrical connection between the two electrode rods 31 and the withstand voltage test equipment, which is a basic prerequisite for performing voltage testing. This prepares for the subsequent voltage breakdown test, allowing the test equipment to apply the required voltage to the object under test through the electrode rods 31.

[0124] Hi-pot test equipment typically features data logging capabilities, recording parameters such as voltage and current during the test, providing a basis for subsequent data analysis and result evaluation. Furthermore, this equipment can generate AC and DC high voltages and measure leakage current applied to insulating materials. The test is conducted by setting the test voltage, AC and DC test voltage type, and the duration of the hi-pot test according to the test plan. After the test, the relevant electrical properties of the sample are inspected.

[0125] In addition, during the test process, the simulator 100 and the withstand voltage test equipment usually have multiple safety protection measures, such as overcurrent protection, overvoltage protection, etc., to ensure the safety of the test process.

[0126] Step S320a: Control the electrode rod 31 to perform a voltage breakdown test on the object to be tested.

[0127] In this step, after the electrode rod 31 clamps the object to be tested, the voltage is applied by controlling the electrode rod 31, and the test officially begins. This step is the core link of the voltage breakdown test, and a gradually increasing voltage is applied to observe whether the object to be tested will experience voltage breakdown. During the test, it is necessary to record the changes in parameters such as voltage and current, as well as the time and voltage value of the voltage breakdown phenomenon. These data are of great significance for evaluating the electrical insulation performance of the object to be tested. By controlling the voltage applied by the electrode rod 31, the voltage breakdown strength of the object to be tested can be accurately evaluated. At the same time, due to the good contact between the electrode rod 31 and the object to be tested, the accuracy and reliability of the test results can be ensured. During the test, it is necessary to continuously monitor the safety of the test environment, including the contact between the electrode rod 31 and the object to be tested, changes in voltage and current, etc. If any abnormality is found, the test should be stopped immediately and appropriate safety measures should be taken.

[0128] Reference Figure 10 , Figure 10 yes Figure 8 In the second flowchart of the specific steps of step S30, in some embodiments, the test electrode is an electrode rod 31, and step S300 controls the test electrode to test the object to be tested, including:

[0129] Step S310b: driving at least one of the two electrode holders 20 to move so that the two electrode rods 31 abut against each other.

[0130] It should be noted that when the two electrode rods 31 are in contact, the scale of the pointer corresponding to the ruler is 0 mm.

[0131] In addition, in this step, the test electrode is clearly defined as an electrode rod 31, and at least one electrode holder 20 is driven to move so that the two electrode rods 31 are in contact with each other. This is a key step in the preparation stage, ensuring that the two electrode rods 31 are in contact before the test, providing a basis for subsequent current flow and arc formation.

[0132] Step S320b: Control the simulator to be in an electrical arc starting verification state, so that the two electrode rods 31 are separated and an arc is formed between the two electrode rods 31, and the arc is used to contact the object to be tested.

[0133] It should be noted that when the simulator is in the electrical arc verification state, the two electrodes 31 are connected to a DC power supply and a load, allowing a current to flow between the two electrodes 31. This is the core of the testing process. The presence of this current verifies the integrity and stability of the electrical connection. This step introduces current, providing the necessary energy conditions for subsequent arc formation. Furthermore, the use of a DC power supply helps maintain current stability, improving test accuracy.

[0134] In this step, the simulator is controlled to an electrical arc verification state, separating the two electrode rods 31 and forming an arc between them. Arc formation is a key test indicator, used to contact the test object and verify its electrical performance. This step achieves the generation of an arc. The high temperature and high energy characteristics of the arc enable effective electrical contact and verification of the test object. After the test, the sample is inspected for the effects of the arc.

[0135] Arcing is a gas discharge phenomenon in which current is conducted through ionized air, producing a plasma characterized by extremely high temperature, high energy, high brightness, and instability. In high-voltage circuits, arcing often occurs when high-current contactors and short-circuit protectors are switched on and off, causing hazards such as ablation, adhesion, and explosion. The simulator enables stable electrical arcing, verifies the arc resistance of different insulating materials and conductors, assesses the impact of arcing on insulating materials and conductors, studies and analyzes the mechanisms and risks of arcing in high-voltage circuits, and identifies potential design flaws in high-voltage components such as contactors, fuses, and connectors.

[0136] Reference Figure 11 , Figure 11 yes Figure 8 In the third flow diagram of the specific steps of step S30, in some embodiments, the simulator further includes a dripping pot 70, which is mounted on the base 10 and corresponding to the test station. The test electrode is the CTI electrode 32, and step S300 controls the test electrode to test the test object, including:

[0137] Step S310c: Control the simulator 100 to be in the CTI test state, and arrange the two CTI electrodes 32 at intervals.

[0138] In this step, the simulator 100 is set to the CTI test state, which means that the test parameters, environmental settings, etc. have been pre-configured in accordance with the standards of the CTI (relative tracking index) test, ensuring the accuracy and effectiveness of the test. The two CTI electrodes 32 are arranged at intervals, which is one of the key steps in performing the CTI test. Reasonable spacing can ensure that the dripping liquid during the test can be evenly distributed on the object to be tested, and the distance between the electrodes is moderate, which is convenient for observing and measuring the tracking phenomenon. Using a special CTI electrode for testing can significantly improve the accuracy of the test. The design and material selection of the CTI electrode are usually matched with the test standards and can better simulate the conditions in actual use.

[0139] It should be noted that when the simulator is in the CTI test state, the distance between the two CTI electrodes 32 is 4 mm, and the scale of the pointer corresponding to the ruler is 4 mm.

[0140] Step S320c: controlling the dripping pot 70 to drip liquid toward the object to be tested.

[0141] In this step, the dripping pot 70 is controlled to drip liquid toward the object to be tested. The dripping liquid typically contains an electrolyte solution to simulate the damp or contaminated conditions that may be encountered in actual applications. This step wets the surface of the object to be tested, helping to accelerate the onset of tracking, thereby more quickly evaluating its electrical insulation performance. By controlling the dripping speed, volume, and frequency, the test conditions can be further adjusted to meet different testing requirements.

[0142] Step S330c: Control the two CTI electrodes 32 to perform a CTI test on the object to be tested.

[0143] In this step, after connecting the CTI electrode 32 to the pulsed DC power supply and load, the power supply and load are started, and the test officially begins. This marks the entry of the test process into a critical stage, namely observing and measuring the leakage tracking phenomenon of the object to be tested. During the test process, changes in parameters such as voltage and current, as well as the time and extent of the leakage tracking phenomenon, can be recorded. These data are of great significance for evaluating the electrical insulation performance of the object to be tested. When performing a CTI test, it is necessary to ensure the safety of the test environment. When connecting the pulsed DC power supply and load, the integrity and safety of the circuit should be checked to prevent safety accidents such as electric shock.

[0144] Additionally, CTI electrodes 32 serve as test electrodes and are connected to a pulsed DC power supply and a load. The pulsed DC power supply provides a varying current to simulate the electrical stresses encountered in real-world applications. This step enables CTI testing of the test object. The specialized design of the CTI electrodes 32 and the use of a pulsed DC power supply facilitate more accurate evaluation of the electrical insulation performance of the test object under humid or contaminated conditions. By monitoring the onset and progression of tracking, the CTI value of the test object can be determined, thereby assessing its electrical safety performance.

[0145] In addition, since the CTI electrodes 32 are connected to a pulsed DC power supply and a load, the DC power supply and the load are started, and a conductive path is gradually formed on the surface of the insulated object to be tested under the combined action of the electric field and the electrolyte. A prescribed stable current is formed in the circuit where the two CTI electrodes 32 and the object to be tested are located, so as to perform a CTI test on the object to be tested, and check the status of the sample after the test. Tracking may cause creepage, breakdown short circuit and fire risks in the insulating material. The simulator drives the electrode holder 20 to move, so that the distance between the two CTI electrodes 32 can be adjusted as needed. The temperature measurement module 110 can synchronously measure the temperature of the object to be tested, so that the simulator can verify the tracking resistance of different insulating materials and identify potential defects in high-voltage insulating materials.
