Developing of the Contact Interval Rated Model of the High-speed DC Circuit Breaker VAB 49 for the Analysis of Work Features of LHC/DQSB Switches of Energy Extraction System out of LHC Main Ring Magnets
Protvino, 2011. – p. 12, figs. 6, tables 3, refs.: 6.


The paper presents the results of the modeling of the VAB49 high-speed electromagnetic breaker which is a part of the QBS switches of the LHC superconducting magnet protection system. The breaker model is based on the analysis of electromagnetic processes in contact interval of the given breaker at the time of its disconnecting.
