[0034] Optionally, the detection shell comprises a hollow shell 1 with an opening and a cover plate 2 detachably connected at the opening of the shell. The cover plate 2 is closed at the upper opening of the shell 1.

[0047] It can be understood that the elastic band 7 is elastically clamped on the upper surface of the sensor 9, and plays a role of elastic compression on the sensor 9.

[0048] Optionally, the sensor 9 includes a detachable shielding shell.

[0049] It can be understood that different detachable shielding shells are replaced for the sensor 9 to complete the detection of the electric migration of the sensor 9 under different variables.

[0050] Optionally, the detected device includes a shell 10 and an electric heating wire 11 arranged inside the shell, and the sensor 9 is a temperature sensor.

[0051] Specifically, the sensor 9 is a temperature sensor, and the electric heating wire 11 is used to heat to generate heat, and the temperature sensor detects the temperature to determine the accuracy of the temperature sensor detection result and the stability of the detection output transmission, and the influence degree of the temperature sensor in the high-voltage strong magnetic field environment is determined based on this.

[0052] Optionally, the sensor 9 can also be set as a humidity sensor, and the electric heating wire 11 is replaced by a humidifier corresponding to the humidity sensor, and the same test steps are adopted.

[0053] The overall structure of the electromigration analysis system includes a detection shell, a high-voltage line 4, a sensor 9, a device under test, and a detection analysis host computer 12. The detection shell forms a closed electromigration analysis space, and the cover plate 2 is connected to the shell 1 by threads or buckles, realizing a detachable design and facilitating the replacement and maintenance of the sensor 9. The high-voltage line 4 passes through the detection shell and forms a high-voltage strong magnetic field environment inside. The sensor 9 is placed in the high-voltage strong magnetic field environment for real-time monitoring of the temperature changes or other parameters of the device under test. The device under test is connected to the sensor 9, which has a double-layer design, with an outer shell 10 and an inner layer with an electric heating wire 11 for simulating different temperature environments to comprehensively evaluate the performance of the sensor 9. The detection analysis host computer 12 is connected to the sensor 9 for detecting the working state and signal transmission stability of the sensor 9 in the high-voltage strong magnetic field environment, and has a data processing module for real-time analysis of the signals transmitted by the sensor and evaluation of its electromigration characteristics.

[0054] The design and implementation of the electromigration analysis system greatly improve the accuracy and reliability of sensor performance evaluation. Due to the ability to simulate extreme high-voltage strong magnetic field environments, this system has wide application prospects in the power industry, aerospace field, and scientific research institutions. For example, in the power industry, it can help evaluate the working stability of sensors in high-voltage environments such as substations and high-voltage transmission lines; in the aerospace field, the system can be used to test the performance of sensors in space environments or strong magnetic fields such as aircraft engines; scientific research institutions can use this system for the development and performance verification of new materials and new sensors, providing strong support for technological progress.

[0055] The internal structure of the shell 1 can be seen in the support ring 6, which has rubber support strips 8 on the inner wall for fixing the sensor 9 and reducing its vibration in the high-voltage strong magnetic field environment. The elastic strips 7 are connected between the two sides of the upper opening of the support ring 6, further enhancing the stability of the sensor 9 and reducing displacement. Figure 2 shows the specific position of the sensor 9 and the wiring method of the high-voltage line 4 inside the detection shell, ensuring the formation of a high-voltage strong magnetic field environment. The material of the shell 1 shown in the figure can be high-impedance ceramic, which has excellent electromagnetic shielding performance to ensure the purity of the sensor signal. The cover plate 2 can be transparent, facilitating the observation of the physical state changes of the sensor 9 in the high-voltage strong magnetic field environment. Figure 2 The detailed structure of the electromigration analysis system is provided, which helps to understand how to form and control the high-voltage strong magnetic field environment and how to reduce the influence of external interference on sensor performance evaluation.

[0056] The design of the detection enclosure not only provides the extreme environment required for sensor 9 testing, but also significantly reduces the impact of vibration on test results through the use of rubber support strips 8 and elastic strips 7. This is particularly important when testing high-precision sensors that are extremely sensitive to vibration, such as fiber-optic sensors or micro-electro-mechanical system (MEMS) sensors used for precision measurement. The design of the transparent cover plate 3 allows the tester to directly observe the behavior of the sensor under different conditions, which is directly helpful for fault diagnosis and phenomenon analysis. In the maintenance and monitoring of power equipment, this system can ensure the stability and reliability of the sensor 9 in a complex electromagnetic environment, helping to improve the safe operation level of the power system.

[0057] Figure 5 The double-layer structure of the device under test is shown in detail, and the outer layer is the outer shell 10, and the inner layer uses the electrolytic heating wire 11. The outer shell 10 is made of insulating plastic, forming a good temperature conduction and electromagnetic isolation environment. This design can simulate a high-voltage strong magnetic field environment at different temperatures to comprehensively evaluate the performance of the sensor 9. The position of the electric heating wire 11 is also marked, and its power can be adjusted to meet the testing needs of different sensors under different temperature conditions.

[0058] The adjustable power of the electric heating wire 11 allows the system to simulate a wide range of temperatures from low to high, which is crucial for evaluating the performance of the sensor 9 under extreme temperature conditions. For example, in extremely cold polar regions or extremely hot desert environments, the performance of the sensor 9 will be severely affected, and this system can predict and evaluate these effects in advance, providing reliable data support for the actual application of the sensor.

[0059] Optionally, the sensor 9 is connected to the detection and analysis host computer 12 through a wireless signal transmission device, which reduces the interference of the high-voltage strong magnetic field environment on the signal line and improves the stability and accuracy of signal transmission. This design not only avoids the risk of damage to traditional signal lines in extreme environments, but also simplifies the system structure and improves the testing efficiency.

[0060] Wireless communication can maintain signal clarity and accuracy even in a high-voltage strong magnetic field environment. The application of this technology greatly expands the range and capability of sensor testing, allowing effective sensor performance evaluation in complex environments where signal lines cannot be laid out (such as deep sea, space, or industrial production sites). For sensors that need to work in various extreme environments, such as wireless sensor networks for environmental monitoring, this wireless signal transmission design is an indispensable key technology.

[0061] Exemplarily, Figure 3In the two elastic bands shown in the middle, each elastic band 8 includes two connection points, fixed on both sides of the upper opening of the support ring 6. The elastic band 8 will automatically adjust its shape according to the size and weight of the sensor, further enhancing the fixation effect of the sensor and reducing signal interference caused by vibration. This design ensures the test accuracy of the sensor under extreme conditions and improves the performance of the entire electromigration analysis system.

[0062] The design of the elastic band 8 ingeniously combines mechanics and material science, and by adjusting the elastic coefficient of the elastic band 8, it can adapt to different types of sensors, including miniaturized sensors and heavy industrial sensors. This flexible adaptation capability enables the electromigration analysis system to be used for testing a variety of sensors, not only improving the value of the system, but also making it possible for standardized testing of sensors. In practical applications, this system can be widely used for performance evaluation of various sensors, such as pressure sensors, temperature sensors, and acceleration sensors, providing a powerful testing means to ensure the reliability and effectiveness of sensors in practical applications.

[0063] In summary, the electromigration analysis system, through its unique design, can accurately simulate and control high-voltage strong magnetic field environments, combining wireless signal transmission and elastic fixation technology, to provide a reliable, efficient, and comprehensive testing method for performance evaluation of sensors under extreme conditions. This system not only has important application value in the field of scientific research, but also plays an irreplaceable role in practical engineering fields such as power, aerospace, and environmental monitoring. Through Figures 1 to 5 the detailed description and extended interpretation, the importance and innovation of the electromigration analysis system in the field of sensor testing can be seen, providing strong support for the development and application of related technologies.
