Received: 1 May 2020; Accepted: 16 June 2020; Published: 20 June 2020 Abstract: The prestrike phenomenon in vacuum circuit breakers (VCBs) is interesting but complicated. Previous studies mainly focus on the prestrike phenomenon in single-break VCBs. However, experimental work on prestrike characteristics of double-break VCBs cannot be found in literature. This paper aims to experimentally determine the probabilistic characteristics of prestrike gaps in a double-break VCB consisting of two commercial vacuum interrupters (VIs) in series under direct current (DC) voltages. As a benchmark, single-break prestrike gaps were measured by short-circuiting one of the VIs in a double break. The experimental results show that the 50% prestrike gap d50 of each VI in a double break, which is calculated with the complementary Weibull distribution, was significantly reduced by 25% to 72.7% compared with that in a single break.

Mueller², Oswald Schrott³, Hans Hauser ³ 1 Plansee Aktiengesellschaft, A-6600 Reutte, ² Elektro-Metall, CH-5703 Seon ³ TU-Wien, Institut für industrielle Elektronik und Materialwissenschaften, A-1040 Wien Summary For low voltage switches and specific medium voltage vacuum bottles (7,1 kV / 4 kA) the contact material of choice is WC/Ag with respect to erosion resistance, chopping current and lifetime. All industrial manufacturing processes, which are established, are based on powder metallurgical manufacturing technologies. Besides the mechanical and physical properties of the contact material, the microstructure and homogeneity are essential for the arcing behaviour of the contacts in service. For WC/Ag 60/40 contact material different treatment techniques for preparation of powder mixtures (Mixing, ball milling, planetary ball milling) to improve the homogeneity were investigated. For consolidation of samples the press – sinter – infiltration route was used and by use of micrographs an assessment with respect to homogeneity of microstructure was made. With planetary ball milling homogeneity of WC/Ag 60/40 can be improved without disadvantages on WC particle size and handle- ability of powder mixture. The observed differences in microstructure have no influence on the physical properties of the contact material. Keywords Contact Material, Tungsten-Carbide Silver, Powder Metallurgy, Microstructure, Homogeneity R. Grill et al. RM 20 201 1. Introduction Electrical switchgears are used in the fields of power generation, transmission, distribution, and consumption. Today, vacuum switches (up to 52 kV) are the most important switchgears for power distribution.

  • DC Current Interruption Based on Vacuum Arc Impacted by Ultra-Fast Transverse Magnetic Field
    energies Article DC Current Interruption Based on Vacuum Arc Impacted by Ultra-Fast Transverse Magnetic Field Ehsan Hashemi 1 and Kaveh Niayesh 2,* 1 School of Electrical and Computer Engineering, Faculty of Engineering, University of Tehran, Tehran 1417466191, Iran; [email protected] 2 Department of Electric Power Engineering, Norwegian University of Science and Technology (NTNU), 7034 Trondheim, Norway * Correspondence: [email protected] Received: 24 July 2020; Accepted: 4 September 2020; Published: 7 September 2020 Abstract: In this paper, the effect of an external ultrafast transverse magnetic field (UFTMF) on a vacuum arc in the diffused mode has been studied. According to the results of studies, a novel approach for making a zero-crossing in a DC arc current has been presented. Plasma voltage fluctuations of the vacuum arc, which are caused by UFTMF, have been investigated via finite element simulation and two-fluid description of plasma physics. By making an appropriate UFTMF through an external circuit, the arc current can be commuted successfully from the vacuum interrupter (VI) to a parallel capacitor and charge it up. In this way, a zero-crossing in the arc current can be achieved, and the current will be interrupted by the VI. Simulation results, which are supporting physical backgrounds for this analysis, have been presented in this paper while technological issues for industrial implementation of this concept have been discussed in detail. Keywords: vacuum circuit breaker; vacuum arc; DC circuit breaker; current interruption; vacuum interrupter; magnetic field; plasma physics; zero-crossing 1. Introduction Various studies on vacuum interrupters (VIs) have been performed in recent decades.
