Investigations on the safe stroke of mechanical HVDC vacuum circuit breaker

open access: yesThe Journal of Engineering, 2019
Here, a DC vacuum arc interruption test based on the hybrid high-speed actuator and the method of commutation is carried out in the synthetic loop system. The safe stroke is one of the basic breaking parameters.

Multi-port DC circuit breaker based on dual capacitor current limiting and energy sink

open access: yesFrontiers in Energy Research, 2023
The coupling relationship between the removal of the fault current and the dissipation of the residual energy of the fault line during the fault isolation process of the multi-port capacitive current-limiting DC circuit breaker prolongs the breaking time

A Current-Commutation DC Circuit Breaker with Adaptive Reclosing Capability [PDF]

open access: yesE3S Web of Conferences, 2021
DC faults are critical events in a flexible high-voltage dc (HVDC) grid. Thus, ensuring that the power system returns to normal operation rapidly and reliably after fault isolation is very important. This requires a HVDC breaker. In overhead line systems

DC interruption characteristic of vacuum circuit breaker

open access: yesElectrical Engineering in Japan, 2005
AbstractA high‐speed vacuum circuit breaker (HSVCB) has been investigated. HSVCB makes high‐frequency current superimposed on a fault current so that the current is forced to be zero and is interrupted. Its interruption performance is considered to be dependent on the rate of change of the current (di/dt). As a fundamental research, we investigated the

Parameters design of voltage sharing components for the series multi‐break mechanical switch

open access: yesIET Science, Measurement & Technology, 2022
Series multi‐break mechanical switch is one of the critical components of high‐voltage hybrid DC circuit breakers. However, due to the existence of distributed capacitance, the voltage distribution between the breaks is not balanced.
