要約(英語): This paper describes improvements of current breaking performance in fuse-link by controlling the temperature distribution of the fuse element during pre-arcing process. The fuse element is designed and produced to obtain the simultaneous arc-forming of several interrupting points in the fuse element by controlling the temperature of the interruption point in consideration of the heat generation by current flowing and heat radiation to the surrounding media. The interruption test was carried out to evaluate the current breaking performance. It was confirmed that the current breaking performance of the fuse which controlled temperature distribution was improved in comparison with common structure fuses without temperature controls. Also, it was found that this control method can be applied to fuses of different pattern and thicknesses. In addition, the interruption performance could be improved for different currents conditions used for calculation.
