Development of a new topology of dc hybrid circuit breaker

2013 2nd International Conference on Electric Power Equipment - Switching Technology (ICEPE-ST), 2013
A new topology of dc hybrid circuit breaker based on fast switch and liquid metal fault current limiters(LMFCL) is proposed for medium voltage dc system in this paper. The voltage generated by LMFCL can commutate the fault current into the parallel thyristors and make arcless open of fast switch contacts.

Zero volt switching hybrid DC circuit breakers

Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002
DC distribution networks have the advantage of easy connection of generators of different frequency, fuel cells, and storage devices like batteries and flywheels to a grid and the advantage of a lower current load of the cables. Despite these advantages, often an AC distribution network is chosen because of the lack of reliable DC switchgear.

An Integrated Multi-port Hybrid DC Circuit Breaker

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
A massive number of hybrid DC circuit breakers (HCBs) have to be installed to protect a voltage source converter based multi-terminal DC (MTDC) system, leading to quite high costs. To reduce the implementation cost employing HCB in DC systems, this paper presents an integrated multi-port hybrid DC circuit breaker (IMP-HCB), which consists of an ...

Thyristor-Based Multiport Hybrid DC Circuit Breaker for Multiterminal DC Grid Protection

IEEE transactions on industrial electronics (1982. Print)
Since the multiport hybrid dc circuit breaker (HCB) can share the expensive main breaker among multiple adjacent lines, it is considered as a more cost-efficient choice than typical HCB to isolate the dc-side fault in the large-scale multiterminal dc ...

Hybrid DC Circuit Breaker and Method for Controlling [PDF]

, 2013
A circuit breaker and method of controlling Direct Current is disclosed. The circuit breaker has a primary conduction path (202) comprising a positive temperature coefficient (PTC) device with a positive temperature coefficient of resistance and a mechanical switch (204, CB1) is connected in series with the PTC device.

Modular Hybrid DC Circuit Breaker for Medium-Voltage DC System

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
This paper proposes a new modular hybrid DC Circuit Breaker (DCCB) for Medium-Voltage DC (MVDC) grid system. The proposed DCCB has mechanical switch which is composed of Vacuum Interrupter (VI) and Permanent Magnetic Actuator (PMA). And commutation path which is composed of two IGBTs and diodes is connected to the VI in parallel.
