Numerical Simulation of an Explosively Driven HVDC Circuit Breaker

摘要: High Voltage Direct Current (HVDC) circuit breakers have to suppress high values of currents at voltages in absence current-zero points. This makes the arc interruption more severe than case conventional AC networks. For breaking HVDC networks, a capacitor-inductor set has been inserted parallel with breaker inject reverse current chamber and create artificial In this paper, novel method for injection proposed which pulsed power source (Helical Flux Compression Generator) employed generate opposing current. Numerical simulation high-current presented. purpose, MHD equations describing behavior DC arcs are jointed Generator is coupled simple network. The results indicate that explosively driven can make point properly lead successful consequently. needs much less volume cost comparison sets.
