DC vacuum circuit-breaker

2008 23rd International Symposium on Discharges and Electrical Insulation in Vacuum, 2008
The results of switching tests of a DC vacuum circuit-breaker designed for rated voltage 3.3 kV and rated current 3000A are presented. The circuit-breaker is intended for current interruption in the networks with fault currents up to 30 kA. To interrupt the direct current, the authors used a method of artificial current transition through zero in the ...

Design and Simulation of a Bidirectional DC Circuit Breaker

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
In recent years, DC microgrid has been developing continuously and its application range is more and more wide, which puts forward higher requirements for its protection. This paper proposes a bidirectional DC solid-state circuit breaker (SSCB), which allows power to flow bidirectionally and can be used in bidirectional DC microgrid protection ...

A study on Low-Voltage DC circuit breakers

2013 IEEE International Symposium on Industrial Electronics, 2013
Recently, DC distribution systems become hot issues since DC type loads increase rapidly according to the expansion of IT equipment such as computers, servers, and digital devices; DC type loads will cover 50% for all electricity loads in 2020 which was mere 10% in 2000 [1,2].

Modeling for series arc of DC circuit breaker

2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA), 2017
In electric distribution systems, a series arc occurs when a load and a power source are disconnected from a connector such as a circuit breaker, a socket–plug, or a coupler. In dc systems, the arc is not extinguished unless the arc current decreases to zero. Sustaining plasma arc current can cause huge fire disasters. To cope with the arc faults in dc

A New Z-Source DC Circuit Breaker

IEEE Transactions on Power Electronics, 2010
A novel type of circuit breaker is introduced for operation at medium-voltage dc with future naval ship power systems as a targeted application. The breaker utilizes a z-source LC circuit in order to automatically commutate a main-path SCR during a fault.
