- ПубликацияТолько метаданныеCold test and numerical analysis of the compact 2G HTS power cable(2019) Fetisov, S.; Zubko, V.; Zanegin, S.; Vysotsky, V.; Высоцкий, Виталий Сергеевич© 2019 Published under licence by IOP Publishing Ltd. The R&D project is underway in the Russian Cable Institute to reduce mass and dimensions of HTS cables for such applications as electrical aircrafts or ship propulsion systems. Such compact cables should have minimized diameter compared to other co-Axial HTS cables developed before. Recently we developed and tested the compact cable prototype with three layers in the core and two layers in the shield. As continuation of this project we developed the new cable prototype with four HTS layers in the core and two layers in the shield. Narrower 2G HTS tape with 3 mm width has been used for this cable. Numerical optimization of the cable with analysis of manufacturing errors influence on current distribution has been performed. The method to produce small diameter cable with uniform current distribution has been suggested. The cold test of the compact cable manufactured has been performed at the Russian Cable Institute test facility. We demonstrated that we can control the homogeneous current distributions in a compact cable with the inner diameter of the core ∼10 mm and the outer diameter of the shield ∼20 mm. AC loss measurements in the compact cable demonstrated that they are close to those in previously tested HTS 2G cables with larger diameters.
- ПубликацияТолько метаданныеAnalysis of behaviour of HTS tapes cooled by liquid nitrogen under currents more than the critical current(2019) Zubko, V.; Fetisov, S.; Zanegin, S.; Vysotsky, V.; Высоцкий, Виталий Сергеевич© 2019 Published under licence by IOP Publishing Ltd. For proper HTS device protection knowledge is necessary about the behaviour of HTS tapes cooled by liquid nitrogen at current pulses more than critical current. In our previous works, we performed measurements of HTS tapes at the currents more than critical currents and found the peculiarities on voltage-current characteristics of HTS tapes. Later, the coupled thermal and electric numerical model was developed to analyse the behaviour of the HTS tape in these conditions. The numerical model helped us to understand qualitatively the heat transfer from the HTS tapes to liquid nitrogen. The peculiarities found were connected not only with the nonlinearity of electrical conductivity of the superconductors but with boiling hysteresis phenomenon in the liquid nitrogen as well. In the present paper we made additional suggestions about peculiarities in the nuclear boiling heat transfer. We also described the way to find out the real heat transfer coefficients during convection and nucleate boiling in liquid nitrogen by using data from measurements of voltage-Time characteristics of the HTS tape cooled by liquid nitrogen at current pulses more than critical current.
- ПубликацияТолько метаданныеOptimization and Cold Test of a Triaxial 2G HTS Power Cable With High Current Capacity(2021) Fetisov, S. S.; Zubko, V. S.; Zanegine, S. Y.; Nosov, A. A.; Vysotsky, V. S.; Высоцкий, Виталий СергеевичTriaxial HTS AC power cables, that incorporates three HTS phases wound around a single core within a single cable is considering the optimal solution for low and medium voltages. Such a design permits to save expensive HTS conductor and to increase the power density transmitted. It is difficult to increase the transmission capacity of a triaxial cable by increasing its operating voltage and therefore, insulation thickness between phases. The other way is to increase the operation current by using a multilayer structure in each phase of the triaxial cable. This task demands a complicated optimization analysis and a precise manufacturing technology. Following our previous studies, we developed and tested the triaxial cable prototype with two layers per phase made of ReBCO wire. The optimal parameters of the cable (twist pitch, diameters of phases, etc.) have been determined using the numerical simulation methods developed. DC and AC tests of the cable has been performed. In the result, the feasibility to provide a uniform current distribution in a triaxial cable, each phase of which consists of two layers, has been demonstrated. With the outer diameter of similar to 24 mm only, this is the most compact triaxial HTS power cable manufactured and tested up to date with currents up to 4 kA per phase. The anticipated power transfer with three phases of this cable can he as large as similar to 34 MW.
- ПубликацияТолько метаданныеPossible Designs of Mobile Cryomagnets for Novel Microwave Technologies(2022) Zubko, V. V.; Fetisov, S. S.; Glyavin, M. Y.; Proyavin, M. D.; Vysotsky, V. S.; Высоцкий, Виталий Сергеевич© 2002-2011 IEEE.We considered and analyzed feasible technologies to develop mobile nicrowave devices with 3 T magnetic field generated by a superconducting magnet. Two types of superconducting magnets made of HTS or NbTi wires were analyzed. Three possible cooling methods and cryostats are discussed based on the previously published and tested experience. The cost of superconducting wire and their technology maturity are compared. Then we reviewed cooling methods and cryostats using previous researches and discussed approaches possible. We concluded that the conventional technology with a NbTi magnet working at persistent-mode and a transportable liquid helium cryostat with forced current leads is the best choice. This technology has a technology readiness level of at least 8-9 and is superior in maturity, and therefore reliability, to all others.
- ПубликацияТолько метаданныеThe Feasibility Design Study and Cold Test of the First Model of HTS Cable With the Longitudinal Magnetic Field Effect(2022) Fetisov, S. S.; Zubko, V. V.; Zanegin, S. Y.; Vysotsky, V. S.; Высоцкий, Виталий СергеевичSince the 1970's the effect of the increase of the critical current of superconductors in the longitudinal external magnetic field has been known. The critical current density of a Nb-Ti wire at low longitudinal magnetic fields demonstrated several times the larger value compared with that in a transverse magnetic field. The same phenomenon has been observed for 2G HTS tapes. It is natural to try to use this phenomenon to increase the critical current in DC HTS power cables. In this paper, we present the analysis of feasibility to use the longitudinal magnetic field effect to increase critical currents in practical HTS power cables. The experimental model of the HTS DC cable has been developed, produced, and tested in liquid nitrogen. The increase of the critical current observed when the longitudinal magnetic field generated. This increase coincides with the calculations.
- ПубликацияТолько метаданныеReview of the design, production and tests of compact AC HTS power cables(2020) Fetisov, S. S.; Zubko, V. V.; Nosov, A. A.; Zanegin, S. Y.; Vysotky, V. S.; Высоцкий, Виталий СергеевичPower cables made of high temperature superconductors (HTS) are considered as most advanced applications of superconductivity for electro-energetics. Several cables made of the First Generation (1G) HTS wires have been produced and installed to electrical grids worldwide. Power cables made of the Second Generation HTS wires (2G or Coated Conductors) are in active development. Most basic principles of HTS power cables development have been published in many works since 90-ties. In this Review we would like to present our new developments mostly directed to 2G HTS compact power cables. We are presenting the methods to optimize a design of 2G AC compact power cable providing uniform current distribution among cable layers and the production technology approaches to implement such a design. AC losses measurements in such cables and other test methods are described. Some problems of the development 2G HTS power cables with small diameters are discussed. We presented as examples designs, developments and test results of two major coaxial cables designs: single-phase (cable core and a shield) and three-phase (triaxial: with three coaxial phases).
- ПубликацияТолько метаданныеInfluence of Cabling on Current Characteristics of Round MgB2 Wires With Different Design(2019) Nosov, AlexanderA.; Potanina, Liudmila, V.; Marinin, KonstantinS.; Fetisov, SergeyS.; Vysotsky, VitalyS.; Высоцкий, Виталий СергеевичMgB2 superconductors are currently considered as a prospective for different applications, in particular for use in high-current super-conducting electrical power lines. The MgB2 superconductors are rather sensitive to the strain that unavoidably occur during a cabling process, that is why a standard cabling machine should be adapted for minimization of strain before fabrication of cables based on MgB2 wires. We performed the comparative study of critical current gradation of two round ex situ MgB2 wires during the fabrication the model 18-strand cable. Both wires were produced by the Columbus superconductor and differ by mechanical properties, matrix composition, and initial critical current. Our cabling machine was previously modified for minimization of strain on the base of calculations of strains dependencies on bending and twisting of MgB2 wires. Mechanical properties of MgB2 wires were analyzed as well. The changes of critical currents of both wires during the 18-strand cable fabrication and insulation were measured. The results of calculations, critical currents tests, and mechanical properties are presented and discussed.

- ПубликацияТолько метаданныеThe General Appearance of the Superconducting Magnet System for the Gas-Dynamic Multimirror Trap(2020) Yakovlev, D. V.; Syrovatin, V. M.; Bagryansky, P. A.; Zubko, V. V.; Vysotsky, V. S.; Высоцкий, Виталий СергеевичThe paper presents the evaluation of basic parameters and general appearance of the superconducting magnetic system of the Gas-Dynamic Multimirror Trap - the next-generation magnetic mirror research facility developed by the Budker Institute of Nuclear physics. The major requirements are that the magnetic field would be ramped up from 0.3 to 3 T within 5 seconds, which implies that a special low AC-loss superconducting cable must be chosen for this part of the magnet system. The mirror coils should have the field similar to 12 T with an aperture exceeding typical of large-bore NMR magnets. In accordance with these requirements the optimized magnet system has been evaluated. The system can have modular design and consists of a set of 12 coils with NbTi superconductors and 4 coils made of Nb3Sn superconductor. Preliminary choice of superconducting cables and basic superconductors for the windings has been substantiated. The estimation of stability margins for all coils demonstrated that both NbTi and Nb3Sn coils have enough stability margins, including the operation of NbTi coils at fast changing current. The study demonstrated the feasibility of the optimized superconducting magnet system for the Gas-Dynamic Multimirror Trap with the use of modern low T-c superconductors and state-of-the-art superconducting magnet technologies.
