[0085] Please refer to Figure 2 In one embodiment, the steps of performing a fuse time test include:

[0086] Step B1. Select the fuse time test in the test items in the test function area.

[0087] Step B2: Enter the fuse current, fuse pressure time and fuse maximum power time in the parameter setting of the test function area. The fuse pressure time is the continuous output time of the power supply after the fuse blows. This parameter helps to understand the circuit state after the fuse blows and the behavior of the power supply after the fuse blows. The maximum fuse power time is the maximum power time of the power supply during the test; if the fuse cannot blow within the maximum fuse power time after the test is started, the test will be automatically terminated to avoid equipment damage or safety hazards, ensuring the safety and controllability of the test process.

[0088] Step B3: Select Start Test in the test function area, and the fuse will perform a fusing time test according to the set parameters.

[0089] During the test, the test data is displayed in real time in the echo box of the test function area, including temperature, power-on voltage, power-on current, voltage drop, internal resistance and power loss, so that users can monitor the test process at any time and promptly discover and deal with abnormal situations. After the test, the test results are displayed, including the fuse time and the IT characteristic curve of multiple fuse tests (the change curve can be seen after more than two tests, and only one test point is depicted for a single time), which helps users to fully understand the performance of the fuse.

[0090] The above-mentioned operating steps for the fuse time test are simple and intuitive. The user only needs to select the corresponding test items and parameter settings in the test function area of ​​the touch screen to complete the test preparation, which greatly simplifies the operation process and improves the test efficiency without the need for additional data recording and analysis steps. By adjusting the parameters such as the fuse current, the fuse pressure time and the maximum fuse time, the user can simulate different working conditions to evaluate the fuse performance under different conditions.

[0095] During the test, the test data, including temperature, power-on voltage, power-on current, voltage drop, internal resistance and power consumption, are displayed in real time in the echo box of the test function area, so that users can monitor the test process at any time and find and deal with abnormal situations in time. After the test, the test results are displayed, including the number of runs, remaining cycle time and fuse time, so that users can fully understand the performance of the fuse in the endurance test.

[0096] The above-mentioned operation steps for endurance testing are simple and intuitive. The user only needs to select the corresponding test items and parameter settings in the test function area of ​​the touch screen to complete the test preparation, which greatly simplifies the operation process and improves the test efficiency without the need for additional data recording and analysis steps. By adjusting the parameters such as the durable power-on current, durable power-on time, durable power-off time and the number of durable power-on and power-off cycles, the user can simulate different working conditions to evaluate the durability performance of the fuse under different conditions.

[0098] Step D1: Select pulse test from the test items in the test function area.

[0099] Step D2: Input the pulse power-on current, pulse power-on time, pulse power-off time and the number of pulse power-on and power-off cycles in the parameter setting of the test function area.

[0100] Step D3, select Start Test in the test function area, and the fuse will perform a cyclic on and off pulse test according to the set parameters until the test is completed or the fuse blows.

[0101] During the test, the test data, including temperature, power-on voltage, power-on current, voltage drop, internal resistance and power consumption, are displayed in real time in the echo box of the test function area, so that users can monitor the test process at any time and find and deal with abnormal situations in time.

[0102] The above-mentioned operation steps for pulse testing are simple and intuitive. The user only needs to select the corresponding test items and parameter settings in the test function area of ​​the touch screen to complete the test preparation, which greatly simplifies the operation process and improves the test efficiency without the need for additional data recording and analysis steps. By adjusting the parameters such as pulse power-on current, pulse power-on time, pulse power-off time and pulse power-on and power-off cycle times, the user can simulate different working conditions to evaluate the pulse performance of the fuse under different conditions.

During the test, if the fuse blows, the blown current and blown time are displayed; if the fuse still does not blow after the current increases to the cut-off current, the test is completed, so that users can fully understand the performance of the fuse in the current gradient test.

[0108] The above-mentioned operation steps for the current gradient test are simple and intuitive. The user only needs to select the corresponding test items and parameter settings in the test function area of ​​the touch screen to complete the test preparation, which greatly simplifies the operation process and improves the test efficiency without the need for additional data recording and analysis steps. By adjusting the parameters such as the starting current, cut-off current, current increment interval and current increment, the user can simulate different working conditions to evaluate the current gradient performance of the fuse under different conditions.

[0109] Please refer to Figure 6 In one embodiment, the steps of performing the current cycle impulse test include:

[0110] Step F1, select the current cycle impact test in the test items in the test function area.

[0111] Step F2: Input the impulse current and the file cycle times in the parameter setting of the test function area. The file cycle times determines the number of times the test needs to be repeated.

[0112] Step F3, select the national standard sequence file or the custom sequence file in the parameter setting of the test function area. The national standard sequence file provides a standardized test process to ensure the consistency and comparability of the test; while the custom sequence file allows the user to set a specific test sequence according to their own test requirements, which improves the flexibility and applicability of the test; the national standard sequence file or the custom sequence file includes detailed information such as sequence length, number of cycles, link file, single-step sequence mode, parameter value, slope, single-step running time parameters, etc., providing comprehensive guidance for the test.

[0115] Step F6, after the test is completed, select waveform preview in the test function area, and several (such as two) cycle simulation waveforms will be automatically generated. The simulation waveform shows the changes in parameters such as current and voltage during the test. Through the waveform preview, the user can more intuitively understand the dynamic performance of the fuse in the current cycle impact test, providing strong support for fuse design and performance improvement.

[0116] During the test, the test data, including temperature, power-on voltage, power-on current, voltage drop, internal resistance and power consumption, are displayed in real time in the echo box of the test function area, so that users can monitor the test process at any time and promptly discover and handle abnormal situations. During the test, if the fuse blows, the blow time and number of cycles are displayed; if the test is completed and the fuse is still not blown, the test result and number of cycles are displayed, so that users can fully understand the performance of the fuse in the current cycle impact test.

[0117] The above-mentioned operation steps for current cycle impulse test are simple and intuitive. The user only needs to select the corresponding test items and parameter settings in the test function area of ​​the touch screen to complete the test preparation, which greatly simplifies the operation process and improves the test efficiency without the need for additional data recording and analysis steps. By adjusting the impulse power-on current and file cycle number parameters and selecting different sequence files, the user can simulate different working conditions to evaluate the current gradient performance of the fuse under different conditions.

The custom sequence file can adapt to the testing requirements of fuses of different models and specifications. By adjusting the parameters in the sequence, the user can easily test different types of fuses without changing the test equipment or rewriting the test program.

[0121] The above-mentioned operation steps for the current cycle impact test are simple and intuitive. The user only needs to input the file number of the custom sequence file to be set to enter the editing interface and adjust the parameters of the custom sequence file.

[0122] In one embodiment, the electronic load module cooperates with the voltage and temperature collectors to jointly construct an efficient and accurate fuse testing system, which realizes the measurement of the voltage drop and temperature internal resistance of the fuse. The voltage collector is responsible for collecting the voltage drop data at both ends of the fuse in real time, and the temperature collector is responsible for monitoring the temperature change of the fuse in real time. During various working condition tests, the electronic load module collects the power-on current, fuse time, voltage drop and temperature data in real time, and automatically calculates the internal resistance and power loss of the fuse at different temperatures. Internal resistance is one of the important indicators for measuring fuse performance, which reflects the degree of resistance of the fuse to current.
