Fuse Simulation And Testing System Based On LabVIEW

Nowadays the electrical equipment update rapidly, fuses always play the important role of protecting valuable devices and ensure the safe operation of the circuit. In recent years, the fault of fuses and the incorrect operation accidents happened frequently, the economic losses are increasing year by year, and these accidents are mostly caused by inaccurate test of parameters for the fuses design, therefore the accurate test for the parameters of fuses is very important.The traditional testing instruments for fuses always have the shortcomings like overpriced, single function, large equipment and extending difficulties. The test methods also ignore the effect of melt changes and material parameters for the measurement results in actual using condition. For low-voltage fuses, they have few measuring equipment since the request for the parameter is not strict, for high-voltage fuses since the cost is too high, at the same time the experiment process is complex, so it is not often being used and research for the measuring equipment, and the current research fields lack of an instrument and design for both high-voltage and low-voltage fuses.This paper puts forward a fuses simulation test system based on Lab VIEW. For high-voltage fuses, on the basis of thermoelectric theory to establish the model in ANSYS, with the consideration of the influence of melt condition and material parameters curve to achieve the most accurate simulation test and display the image and data of the result. For low-voltage fuses using the program LabVIEW panel design procedures, make the three important parameters in accordance with the national standards for accurate testing and recording. The man-machine interface is easy for operation, the results are obvious, and the virtual instruments reflect its powerful function. The system increased security function for the program and results of the test and simulation, which can ensure that the testing system can safely and reliably be used by users.Finally this paper put the high-voltage simulation data and low-voltage test data together, and uses the manufacture data for comparison. The results shows that the test is highly accuracy, it is suitable for widely used in the future. Meanwhile the test equipment can be quickly changed according to the requirements of testing objects, in this way this system can achieve the design goal.
