    It is strongly desired for DC fuse that a compatibility of high arc resistance(rarc) during a DC arc interruption and high insulation resistance(Rins) after the DC arc interruption. This paper describes a trial experiment of DC arc interruption under following conditions. (1) Copper(Cu)-element arrangement in silica-sand filling space(designated as "S-wo"), (2) Arrangement of a polymer fuse-case filled with the silica-sand around the Cu-element(designated as "S-CaseA"), and (3) Arrangement of a polymer narrow-section around an arc-ignition point of Cu-element in the silica-sand filled fuse-case(designated as "S-CaseB"). The damping DC with a prospective peak of 1000 A was energized to the Cu-element to ignite the DC arc. As a result, the compatibility of high rarc and high Rins was successfully achieved only under the S-CaseB condition. These high rarc and high Rins can be interpreted from the shrinking of arc conductive diameter by the silica-sand filled inside the fuse-case and formation of insulation layer by the ablation of the polymer-narrow section.

    Concerning DC arc quenching phenomenon in silica sand filling space, we have proposed a new method for raising an arc column resistance (rcol) by use of polymer-material arrangement. This paper reveals physical factors for rcol rise on the bases of experimental results using the following cylinders made of: (i) Quartz (SiO2) and (ii) PMMA ((C5H8O2)n) with various inner diameters ϕ. For ϕ = 2 mm case, rcol measured for a PMMA cylinder arrangement indicated higher rcol at low current region, while almost same rcol around current peak. For ϕ = 3 mm case, rcol for the PMMA cylinder was lower than rcol for the quartz case at high current region, while almost comparable between these conditions at low current region. For ϕ = 5 mm case, rcol were almost same during the arc quenching process. To discuss the effect of the rcol rise, the followings were also performed: (i) observation of cylinders after arc quenching and (ii) calculation of the electron density of SiO2/Cu or PMMA/SiO2 mixture vapors. It is concluded that, at high current region, rcol can increase due to the shrinking of the arc conductive diameter caused by the cylinder hole and the silica sand filled inside the cylinder hole. On the other hand, the admixing of the PMMA ablation vapor increases rcol at low current region in the present experiment. © 2021 Institute of Electrical Engineers of Japan.

    In this study, experiments pertaining to direct current (DC) interruptions are performed in an arc-quenching chamber filled with silica sand. First, the arc column resistance is measured during DC arc-quenching to demonstrate the elementary aspects of the arc in the silica-sand-filled space. Subsequently, an arrangement comprising a polymer cylinder between electrodes in the silica-sand-filled space is proposed to increase the arc column resistance during DC arc-quenching. A polymethyl methacrylate (PMMA) cylinder is used in the experiments. Measurement results indicate that the arrangement of the PMMA cylinder causes the arc column resistance to increase approximately twofold in comparison with the no-PMMA cylinder arrangement. Finally, the effect of increasing the arc column resistance is discussed in terms of PMMA and silica vapor. © 2021 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

    <p>DC arc interruptions were carried out under following two conditions: (1) silica sand filling without any cylinder arrangement (designation: Silica), and (2) The silica sand filling with a quartz cylinder arrangement (designation: SilicaQuartz). During these experiments, optical emission spectroscopy (OES) measurements were carried out to investigate an arc column resistance rise by the quartz cylinder arrangement. An arc temperature <i>T</i> and a Cu vapor concentration were evaluated from the OES results. As a result, <i>T</i> were measured to be around 24 kK for the Silica condition and 17kK for the SilicaQuartz condition at a current peak. The Cu vapor concentration under the Silica condition gradually decreased with <i>T</i> decaying. On the other hands, the quartz cylinder arrangement in the silica sand filling space drastically decreased the Cu vapor concentration during an arc-quenching process. This drastic decrease in the Cu vapor concentration is one of key factors to increase <i>r</i><sub>col</sub> under the cylinder arrangement in the silica sand filling space. This verification result can be useful to increase an interruption capacity of fuse.</p>

    <p>The gases used in high voltage electric power equipment are required to withstand against an externally applied electric field strength. It is therefore essential to find out the electrical insulation strength of the gas. However the high temperature gas formed after the current zero through the arc extinction process in a circuit breaker shows different insulation strengths from that at room temperature, because the high temperature gas consists of various molecular products different from the original gas at room temperature. The CF<sub>3</sub>CFCH<sub>2</sub> (called as HFO-1234yf) at room temperature is known to have a remarkable electrical insulation property similar to SF<sub>6</sub>. After describing the products generated in CO<sub>2</sub> gas mixture with O<sub>2</sub> and HFO-1234yf decompositions at temperatures below 3000K, this paper mentions dielectric breakdown properties of the mixtures in view of the molar fractions of the molecular products. Discussions are furthermore made to compare dielectric breakdown properties of CO<sub>2</sub> gas and CO<sub>2</sub>/O<sub>2</sub> gas mixture at high temperatures.</p>

    The spatial distribution of the Ti vapor admixture ratio (X Ti) was determined together with Ti excitation temperature () from two-dimensional (2D) optical emission spectroscopy (OES) during Ti feedstock injection into an Ar induction thermal plasma (ICTP) torch for Ti nanoparticle synthesis. The X Ti is one important parameter affecting ICTP properties such as its electrical conductivity. The value of X Ti was estimated from the radiation intensity ratio of the Ar atomic line to the Ti atomic line, and obtained from 2D OES observation. Furthermore the electron density (n e) was also determined from the estimated results of and X Ti through the equilibrium composition. These 2D OES results revealed as 2500-4000 K at around the central axis of the ICTP torch, although it was higher than 4000 K in the off-axis region. In the off-axis region, X Ti and n e were much higher than in the on-axis region.

    Using 20kW Ar-H-2 pulse-modulated induction thermal plasma (PMITP) with time-controlled feeding of feedstock (TCFF), numerous Si nanowires were synthesized rapidly at 1,000mgh(-1) without the intentional addition of catalysts. The PMITP + TCFF method is our original method for nanomaterial synthesis. The PMITP periodically provides a unique field including higher-temperature plasma during "on-time" and a lower-temperature plasma during "off-time". For rapid and efficient evaporation, metal-grade Si powder feedstock was intermittently injected synchronously into the generated Ar-H-2 PMITP. The synthesized products were analyzed using various analytical techniques. The synthesized products were Si nanowires 10-30 nm in diameter with a SiOx surface layer.
