Abstract
Cables with high current capacity are used in power devices, including special-purpose ones operating in impulse modes. It is important to ensure low inductance of such cables, because these type cable products are often used as connecting products. This article discusses the problems that arise in the design and manufacture of special low-inductance impulse cables (SLIC) for power supply and protection of the superconducting magnetic system of the ITER reactor (France), the distinguishing features of which are the optimum ratio of insulation thickness and throughput at low inductance.
Highlights
At the initiative of the USSR in 1985, a number of states joined together to implement the Tokamak project - to create conditions for controlled thermonuclear fusion
In 1992, Russia, the European Union, Japan and the United States signed a quadrilateral agreement on the development of ITER (International Thermonuclear Experimental Reactor)
Before the beginning of each operating cycle, the energy in the poloidal magnetic system ITER will be up to 8 GJ [1]. This energy will be used up to initiate breakdown of the gas mixture and the onset of the rise of the plasma current on the torus bypass [2]. These processes are implemented on special hybrid high-current switches and powerful energy-absorbing resistors, which dissipate the energy of the coils of the poloidal system when switches operate
Summary
At the initiative of the USSR in 1985, a number of states joined together to implement the Tokamak project - to create conditions for controlled thermonuclear fusion. Before the beginning of each operating cycle, the energy in the poloidal magnetic system ITER will be up to 8 GJ [1] In part, this energy will be used up to initiate breakdown of the gas mixture and the onset of the rise of the plasma current on the torus bypass [2]. This energy will be used up to initiate breakdown of the gas mixture and the onset of the rise of the plasma current on the torus bypass [2] These processes are implemented on special hybrid (mechanical and semiconductor) high-current switches and powerful energy-absorbing resistors, which dissipate the energy of the coils of the poloidal system when switches operate. Due to the specificity of the pulse operating modes, the busbars are not suitable for the ITER system
