Description
This paper mainly introduces the seismic analysis of the high-power dc reactor prototype, whose functions are to limit the ripple current and the increasing rate of fault current in the ITER poloidal field (PF) converter. The stacked reactors with the assembly dimension (L×W×H) of 2955 mm×1639 mm×3296 mm and weight about 5 tons are fixed to the steel base by five support components. In order to evaluate the seismic response of the structure under specific seismic excitation, a method based on response spectrum is adopted in this paper. The design earthquake spectrum of seismic level one (SL-1) with damping coefficient of 2% as well as 4% provided by ITER is applied as load. In addition, the simulation analysis is introduced in detail and the results as the displacements, stresses and reactive forces are also presented. This analysis could provide reference for the foundation design of dc reactor, as well as make a contribution to the similar seismic design work.
