要約(日本語): The direct current (DC) fuses are expected to increase current interruption capability. The arc resistance rcol generated in the fuse determines the DC interruption process and is thus required to be raised to a higher magnitude. As one solution, the authors have found that polymer material installation with silica-sand can rise rcol in our earlier works. In this report, first, measurement results of rcol are described for the following two types of the fuse element: (i) the fuse element painted with silicone resin and (ii) the fuse-element painted with no silicone. The experimental results showed that the fuse element (i) achieved higher rcol during the arc quenching process. Secondly, discussions on the rise in rcol are made, based on the chemical composition and the resultant electrical resistivity of the decomposed silica-sand vapor mixed with silicone vapor.
