[0062] like Figure 1 As shown, Figure 1This is a schematic diagram of a performance test device for an insulating component provided in the first embodiment. The performance test device 100 for an insulating component includes: a control module 101, a first clamping member 102, a second clamping member 103, a temperature control module 104, and a temperature sensor 105. It should be noted that, in Figure 1 In the corresponding embodiment, one temperature control module 104 and one temperature sensor 105 are shown, but in other embodiments, the device 100 may include at least two temperature control modules 104 and / or at least two temperature sensors 105 .

[0063] The first clamping member 102 is connected to the control module 101, and the second clamping member 103 is grounded. The first clamping member 102 and the second clamping member 103 are used to clamp the insulating member 200; at least one temperature control module 104 is set at a first distance from the insulating member 200 and is connected to the control module 101; at least one temperature sensor 105 is set at a second distance from the insulating member 200 and is connected to the control module 101, and is used to obtain a sensed first temperature and transmit the first temperature to the control module 101; the control module 101 is used to determine power adjustment information based on the first temperature and a preset second temperature; use the power adjustment information to adjust the operating power of at least one temperature control module 104; output a first voltage to the first clamping member 102; and determine the performance test result of the insulating member 200 based on the first voltage.

[0064] In some scenarios, the insulating member 200 is used in a cable. Exemplarily, the insulating member 200 may include a conductor and the insulating material surrounding the conductor, with the insulating member 200 cut from the insulating material. In some possible embodiments, the insulating member 200 is in the form of a sheet. Exemplarily, the insulating member 200 is in the form of a circle, a polygon, or a ring. For example, the polygon is a triangle, a rectangle, or a pentagon.

[0065] In some possible embodiments, the distances between the multiple temperature control modules 104 and the insulating member 200 are the same, or the distances between the multiple temperature control modules 104 and the insulating member 200 are different.

[0066] In some possible implementations, the control module 101 may determine the number of operating temperature control modules 104 based on the accuracy and power consumption requirements of the performance test. For example, at least one temperature control module 104 is connected to the control module 101 via at least one first switch, and the control module 101 controls the operation of the temperature control module 104 by controlling the on / off state of each of the at least one first switch.

[0067] The temperature sensor 105 is a fiber optic temperature sensor. In other possible embodiments, the temperature sensor 105 may be a thermistor, an infrared temperature sensor, or a laser temperature sensor.

[0068] In some possible implementations, the control module 101 may determine the number of operating temperature sensors 105 based on the accuracy and power consumption requirements of the performance test. For example, at least one temperature sensor 105 is connected to the control module 101 via at least one second switch, and the control module 101 controls the operation of the temperature sensor 105 by controlling the on / off state of each of the at least one second switch.

[0069] In some possible embodiments, the first distance may be greater than the second distance, or the first distance may be less than or equal to the second distance. In some possible embodiments, the distances between the plurality of temperature sensors 105 and the insulating member 200 are the same, or the distances between the plurality of temperature sensors 105 and the insulating member 200 are different.

[0070] When the at least one temperature sensor 105 includes a plurality of temperature sensors 105, each of the plurality of temperature sensors 105 may transmit a sensed first temperature to the control module 101. The first temperatures sensed by different temperature sensors 105 may be the same or different.

[0071] The preset second temperature represents the temperature required for the current performance test (also referred to as the first performance test). In some possible embodiments, determining power adjustment information based on the first temperature and the preset second temperature includes determining a third temperature of the insulating member 200 based on the first temperature, and determining the power adjustment information based on the third temperature and the second temperature. In some possible embodiments, the power adjustment information may include at least one of the following: a voltage value provided to at least one temperature control module 104, a current value provided to at least one temperature control module 104, a power value provided to at least one temperature control module 104, and a rotational speed value provided to a wind-heating module included in at least one temperature control module 104.

[0072] In some possible embodiments, the magnitude of the first voltage and / or whether the first voltage is a DC voltage or an AC voltage may be determined by the control module 101 based on application environment information of the insulating member 200. For example, when the insulating member 200 is a cable, the application environment information of the insulating member 200 is high-voltage direct current (HVDC) environment information, the magnitude of the first voltage may be high voltage (e.g., within a range of 1 kV to 9000 kV), and the first voltage may be a DC voltage.

[0073] In some possible embodiments, such as Figure 1As shown, the device 100 may also include a current detector 106, a first end of the current detector 106 is connected to the control module 101, a second end of the current detector 106 is connected to the first clamping member 102, and the second end of the current detector 106 is also connected to the control module 101. The control module 101 determines the current passing through the current detector 106 based on the voltage across the current detector 106 and the resistance of the current detector 106, and determines the performance test result of the insulating member 200 based on the first voltage and the current passing through the current detector 106.

[0074] In some possible embodiments, the performance test result of the insulating member 200 may include at least one of the following: the resistance value of the insulating member 200 , the breakdown voltage value of the insulating member 200 , and life information of the breakdown voltage value.

[0075] In an embodiment of the present application, by setting a first clamping member 102 and a second clamping member 103, the first clamping member 102 is connected to the control module 101, and the second clamping member 103 is grounded, the first clamping member 102 and the second clamping member 103 are used to clamp the insulating member 200, so that the control module 101 can determine the performance test results of the insulating member 200; further, by setting at least one temperature control module 104 and at least one temperature sensor 105, the temperature of the environment in which the insulating member 200 is located can be accurately adjusted to the second temperature, so that the control module 101 can determine the performance test results of the insulating member 200 at the second temperature, which is conducive to evaluating the performance of the insulating member 200 when the insulating member 200 is applied to the environment of the second temperature, thereby improving the reliability of the insulating member 200 in the actual working environment.

[0076] In an exemplary embodiment, Figure 2 As shown, Figure 2 A schematic structural diagram of a performance testing device for an insulating component provided in the second embodiment. Figure 2 The corresponding embodiment is in Figure 1 Based on the corresponding embodiment, the control module 101 includes: a processing component 1011 and a temperature regulator 1012 .

[0077] Among them, the processing component 1011 is connected to the first clamping member 102, and is also connected to at least one temperature sensor 105 and a temperature regulator 1012, and is used to obtain the first temperature transmitted by at least one temperature sensor 105; determine the power adjustment information according to the first temperature and the second temperature; output the power adjustment information to the temperature regulator 1012; output the first voltage to the first clamping member 102; and determine the performance test result according to the first voltage.

[0078] The temperature regulator 1012 is connected to at least one temperature control module 104 and is configured to regulate the operating power of the at least one temperature control module 104 according to the power regulation information.

[0079] In the embodiment of the present application, since the temperature regulator 1012 is an independent component and is not integrated with other control devices, the installation process is simplified and the installation cost is reduced. It also makes subsequent maintenance and replacement work more convenient and quick. For example, when the temperature regulator 1012 needs to be repaired or replaced, there is no need to disassemble the entire system on a large scale, and only the independent component needs to be operated. In addition, the independent temperature regulator 1012 allows the user to select the most suitable model and specifications according to actual needs to adapt to different working environments and temperature control requirements.

[0082] The processing unit 1011b is connected to the first clamping member 102 and also connected to the temperature regulator 1012, and is used to determine power regulation information based on the control amount and output the power regulation information to the temperature regulator 1012; output a first voltage to the first clamping member 102; and determine a performance test result based on the first voltage.

[0083] In an exemplary embodiment, Figure 4 As shown, Figure 4 A schematic diagram of the control principle of a temperature control system is provided for an embodiment. In the temperature-controlled high-voltage insulation withstand voltage test device 100, the PID controller is used to accurately adjust the temperature of the system to ensure the stability of the experimental conditions. The PID controller obtains the third temperature of the insulating part 200 and the preset second temperature, and performs closed-loop control of the target parameters through the PID control algorithm by combining the proportional term, the integral term, and the differential term.

[0084] The measured temperature is input into the PID controller. The PID controller output can be expressed by the following formula: ;in, is the proportionality coefficient, is the sampling sequence, For the The deviation signal obtained at the moment, For the The deviation signal obtained at the moment, is the integration coefficient, is the sampling period, is the differential coefficient.

[0085] In the embodiment of the present application, since the temperature controller 1011a is an independent component and is not integrated with other control devices, the installation process is simplified and the installation cost is reduced. It also makes subsequent maintenance and replacement work more convenient and quick. For example, when the temperature controller 1011a needs to be repaired or replaced, there is no need to disassemble the entire system on a large scale, and only the independent component needs to be operated. In addition, the independent temperature controller 1011a allows the user to select the most suitable model and specifications according to actual needs to adapt to different working environments and temperature control requirements.

[0108] In an embodiment of the present application, the display module 109 can send the next temperature to the control module 101 after each performance test is completed, thereby reducing manual intervention and reducing the possibility of human error; in addition, since there is no need to wait for manual input of the next temperature after each performance test is completed, the test cycle is shortened and the overall test efficiency is improved.

[0109] In an exemplary embodiment, Figure 9 As shown, Figure 9 A schematic structural diagram of a performance testing device for an insulating component provided in the eighth embodiment. Figure 1 Based on the corresponding embodiment, the device 100 further includes a moving module 110, a camera module 111, and a display module 109; the moving module 110, the camera module 111, and the display module 109 are all connected to the control module 101; the moving module 110 is used to control the movement of the insulating member 200, and is also used to control the movement of the first clamping member 102 and / or the second clamping member 103;

[0113] The control module 101 is also used to adjust the first thickness to the second thickness based on the performance test results, usage environment information and expected usage time, and transmit the second thickness to the display module 109 so that the display module 109 displays the second thickness; wherein the insulating member 200 of the second thickness supports the use of the expected usage time in the usage environment information.

[0114] In some embodiments, the target image can be a single image or multiple images. For example, each time the camera module 111 takes an image, it can change its own posture so as to take the next image from another direction, thereby obtaining multiple images. Exemplarily, the multiple images may include three images or six images. For example, the camera module 111 can take an image facing the insulating member 200, take an image when looking at the insulating member 200 from the side, and take an image when looking down at the insulating member 200. For another example, the camera module 111 can take an image at six different viewing angles, respectively: front view, upward view, left view, right view, downward view, and rear view.

[0115] In an embodiment of the present application, the control module 101 can identify the attribute information (such as the first thickness) of the insulating member 200 based on the target image provided by the camera module 111, thereby eliminating the need for manual determination of the attribute information of the insulating member 200, thereby improving the efficiency of determining the attribute information; by moving the module 110 to change the position of the insulating member 200, the performance of the insulating member 200 can be automatically tested, without the need for manual movement of the first clamping member 102 and / or the second clamping member 103, as well as the movement of the insulating member 200, thereby improving the testing efficiency of the insulating member 200; in addition, since the control module 101 can also adjust the first thickness to the second thickness, it can automatically determine the second thickness required for the expected usage time in the usage environment information, without the need for manual calculation, thereby improving the efficiency of determining the second thickness and reducing the material selection cost of the insulating member 200.

[0116] In an exemplary embodiment, Figure 10 As shown, Figure 10A schematic diagram of a performance testing device for an insulating member provided in the ninth embodiment. Figure 1 Based on the corresponding embodiment, the at least one temperature sensor 105 includes: a first temperature sensor 1051, a second temperature sensor 1052, and a third temperature sensor 1053; correspondingly, the first temperature includes a first sub-temperature, a second sub-temperature, and a third sub-temperature, and the second distance includes a first sub-distance, a second sub-distance, and a third sub-distance;

[0117] The control module 101 is also used to determine the fourth temperature of the insulating part 200 based on the first sub-temperature, the first sub-distance and the thermal conductivity of the medium between the first temperature sensor 1051 and the insulating part 200; determine the fifth temperature of the insulating part 200 based on the second sub-temperature, the second sub-distance and the thermal conductivity of the medium between the second temperature sensor 1052 and the insulating part 200; determine the sixth temperature of the insulating part 200 based on the third sub-temperature, the third sub-distance and the thermal conductivity of the medium between the third temperature sensor 1053 and the insulating part 200; determine the average temperature of the fourth temperature, the fifth temperature and the sixth temperature as the third temperature of the insulating part 200; and determine power adjustment information based on the third temperature and the second temperature.

[0118] In the embodiment of the present application, by including at least one temperature sensor 105 three temperature sensors 105 , the third temperature of the insulating member 200 can be determined according to the temperatures sensed by each of the three temperature sensors 105 , thereby improving the accuracy of the determined third temperature of the insulating member 200 .

[0119] In an exemplary embodiment, Figure 11 As shown, Figure 11 A schematic structural diagram of a performance testing device for an insulating component provided in the eleventh embodiment. Figure 10 On the basis of the corresponding embodiment, the apparatus 100 further includes a movement module 110 connected to the control module 101;

[0120] The control module 101 is further configured to obtain first thickness and shape information of the insulating member 200; determine, based on the first thickness and shape information, that the first temperature sensor 1051, the second temperature sensor 1052, and the third temperature sensor 1053 are evenly disposed and are at a target distance from the insulating member 200, and output the target distance to the moving module 110;

[0121] The moving module 110 is used to adjust the positions of the first temperature sensor 1051, the second temperature sensor 1052 and the third temperature sensor 1053 according to the target distance, so that the first temperature sensor 1051, the second temperature sensor 1052 and the third temperature sensor 1053 are evenly arranged and the distance from the insulating member 200 is the target distance.

[0123] This invention proposes a high-voltage insulation withstand voltage test apparatus (i.e., the aforementioned insulation component performance testing apparatus 100) with precise temperature control. This apparatus is designed to systematically evaluate the electrical performance and aging characteristics of insulation materials under high-voltage environments (included in the aforementioned performance test results). Apparatus 100 integrates a high-voltage generator (i.e., the aforementioned transformer 1011b2), a control module 101, a temperature control system (i.e., the aforementioned temperature controller 1011a, the temperature control portion of the control console 1011b1, and the temperature regulator 1012), and a temperature sensor 105, enabling precise control and dynamic adjustment of test conditions. The stable electric field provided by the high-voltage generator makes apparatus 100 suitable for various types of withstand voltage tests. The control module 101 utilizes a PID control algorithm, combined with real-time collected temperature data, to automatically adjust system parameters to ensure constant temperature during testing. The temperature control system, through distributed temperature sensors 105, monitors the sample temperature in real time and precisely adjusts it through the heating and cooling apparatus 100. The design of the device 100 significantly improves the accuracy and reliability of experimental data, reduces manual intervention, is suitable for comprehensive evaluation of insulating materials in high-voltage electrical equipment, and provides a scientific and rigorous experimental platform for in-depth research on material properties.

[0124] In the performance testing device 100 for insulating parts in the embodiment of the present application, the following operations can be performed: a high-voltage generator is used to generate the high-voltage electric field required for the test, and different forms of high-voltage output can be selected according to different test requirements; an interactive user interface is used to allow the operator to input test parameters, including at least one of the voltage range, test duration, and temperature setting; the control module 101 and the temperature monitoring system (i.e., the above-mentioned temperature sensor 105) are combined to collect the voltage and temperature data of the test sample in real time, and the high-voltage electric field and temperature control system are dynamically adjusted through a feedback mechanism, so that the electric field strength and temperature in the test environment are accurately maintained within a preset range, thereby ensuring the stability and repeatability of the test conditions.

[0125] The voltage withstand test apparatus (i.e., the aforementioned insulation performance testing apparatus 100) provided in the embodiments of the present application, capable of achieving precise temperature control under high-voltage conditions, is of great significance for improving the testing accuracy of insulation materials and studying their electrical aging mechanisms. Apparatus 100 can precisely control the temperature of test samples under high-voltage electric fields, thereby simulating a realistic operating environment and comprehensively evaluating the voltage withstand capability and aging characteristics of insulation materials under different temperature conditions. Through precise temperature regulation and real-time monitoring, apparatus 100 provides a reliable experimental platform for in-depth research into the electrical properties and lifespan prediction of insulation materials, and has important application value in the development of new insulation materials and the safety assessment of power equipment.

[0126] In some embodiments of the present application, a 220V AC power frequency voltage is connected to a power control console 1011b1. An autovariable voltage regulator within the power control console 1011b1 regulates the input voltage (which can be AC ​​or DC, fixed or variable) to the primary winding of a transformer 1011b2, generating the required high voltage at the high-voltage winding end of the test using the principle of electromagnetic induction. Power control console 1011b1 is used to provide a stable and adjustable high voltage. Transformer 1011b2 precisely controls the voltage applied to the test sample, thereby generating a range of voltages from low to high to meet the withstand voltage testing requirements of different insulation materials.

[0127] When testing the breakdown voltage performance of insulating component 200, it is immersed in insulating oil tank 107 to reduce the impact of corona discharge in the air and maintain a uniform electric field distribution. Oil tank 107 is equipped with a temperature sensor 105 and a heating and / or cooling module to ensure that the temperature within oil tank 107 can be precisely regulated, thereby simulating the temperature environment under actual working conditions.

[0128] In some embodiments of the present application, the temperature control system monitors the temperature in real time by connecting to the temperature sensor 105 in the oil tank 107, and adjusts the temperature in the oil tank 107 through a heater or cooling system. The system includes a display module that allows technicians to set the temperature range and change rate, and can display the current temperature data in real time. In some embodiments of the present application, the console 1011b1 can record in real time the voltage and current applied to the sample and the temperature changes on the surface of the insulating part 200 measured by the temperature sensor 105. The temperature-controlled high-voltage insulation withstand voltage test device 100 can realistically simulate the electrical properties of insulating materials under different environmental conditions through precise temperature control and high-voltage electric field application, combined with real-time and accurate measurement of the temperature sensor 105, and provides an important experimental tool for the development of insulating materials and reliability evaluation of power equipment.

[0129] In some embodiments of the present application, device 100 has the following functions: Temperature sensor 105 enables precise temperature measurement in high-voltage environments, with strong resistance to electromagnetic interference, ensuring the accuracy of measurement data. Furthermore, a built-in temperature control system in device 100 automatically adjusts the heating or cooling of device 100 based on real-time temperature feedback, precisely controlling the sample temperature during the test without manual intervention. The entire process automatically records and analyzes data, reducing the need for manual supervision and significantly improving experimental efficiency and data reliability.

[0130] like Figure 12 As shown, Figure 12 This is a schematic structural diagram of a performance testing device for an insulating component provided in accordance with an eleventh embodiment. The device 100 includes: a first clamping member 102, a second clamping member 103, at least one temperature control module (including a cooling module 1041 and at least one heating module 1042), at least one temperature sensor 105, a temperature regulator 1012, a temperature controller 1011a, a control console 1011b1, a transformer 1011b2, an oil tank 107, and a display module 109.

[0131] exist Figure 12 In a corresponding embodiment, the second clamping member 103 may be connected to the console 1011b1 and grounded through the console 1011b1.

[0132] For the description of each part included in the device 100, please refer to the above description and will not be repeated here.

[0133] The lifespan of insulating materials can generally be described by the empirical formula E^n×t=C, where E is the electric field strength, n is the lifespan exponent, t is the pressurization time, and C is a constant related to the material's properties. In this formula, the constant C depends not only on the inherent properties of the material but is also closely related to the temperature of the experimental or operating environment. Temperature has a significant impact on the physical and chemical properties of insulating materials, which in turn directly affects the value of the constant C. As the temperature rises, the molecular motion of the insulating material intensifies, leading to accelerated chemical reactions and faster material aging. These effects make the material prone to breakdown even at lower electric field strengths, resulting in a significantly shortened lifespan. Therefore, precise temperature control is crucial in voltage withstand tests, as even small temperature fluctuations can have a significant impact on the C value, thereby affecting the accuracy and reliability of the experimental results.

[0134] like Figure 13 As shown, Figure 13 This is a schematic diagram of the components in the oil tank and the cooling module outside the oil tank provided in one embodiment. Figure 13The layout of the distributed temperature sensors 105, the positions of the insulating member 200, the first clamping member 102, and the second clamping member 103, as well as the positions of the heating module 1042 and the cooling module 1041 are described. For a detailed description of the positions, please refer to the above description and will not be repeated here. For example, to reduce temperature measurement errors, three temperature sensors 105 are evenly spaced around the insulating member 200 on a circle with a diameter of 10 cm, forming an equilateral triangle. The collected temperature signal is transmitted to the temperature controller 1011a and controlled according to the temperature set by the technician. The insulating oil in the thermostatic oil tank can be maintained within a set temperature range through a heating and cooling system. The heating system consists of an electric heater that can precisely control the heating power to maintain the oil temperature at the set value. The cooling system consists of a circulating cooling device 100 that absorbs heat from the oil through a heat transfer medium (coolant).

[0135] Technicians can enter relevant parameters for the withstand voltage test through the user interface, including the withstand voltage type (constant withstand voltage test or step voltage test), voltage setpoint, and target temperature. When performing a constant voltage test, technicians only need to enter the test duration and the required electric field strength. The control system will automatically adjust the system voltage by adjusting the voltage regulator to maintain the electric field strength at the set value and automatically reduce the voltage after the set test time is reached. For step voltage tests, technicians need to enter parameters such as the initial voltage, step voltage, and step time. Based on these parameters and the time information of the timer, the system calculates the required voltage at each moment and automatically applies the corresponding voltage at each pressurization time point without manual intervention.

[0136] In summary, through the description of the above specific embodiments and the related illustrations, the temperature-controlled high-voltage insulation withstand voltage test device of the present invention can effectively perform high-voltage withstand tests on insulating materials, while maintaining precise temperature control under high-voltage conditions, ensuring a stable test environment and reliable data. This device is suitable for evaluating insulating materials used in high-voltage electrical equipment and provides a reliable experimental platform for in-depth research on material properties.
