Topology And Breaking Process Of Hybrid Dc Circuit Breaker

Abstract

This study is focused on a general function of hybrid direct current circuit breakers. Theone of topics is design topology of these circuit breakers with all necessary branches. Mainly, thestudy deal with their principles of interruption of fault direct current. The description of issue is ingeneral and then for the specific interesting proposals. The main purpose of these protections iscontinuous reducing the fault current to the current-zero outside the mechanical breaker contactswhich conduct solely the nominal current.
