One of the main challenges limiting the development of DC systems is the rapid removal of DC faults, and DC circuit breakers, as key components for protecting DC power supply
This study proposes a hybrid high-voltage DC circuit breaker with an energy absorption branch of a parallel arrester structure,
The force of closing spring under the minimum energy required f or closing of high-voltage circuit. breaker is the minimum force allo wed. When the force of closing spring f=2656.2N (energy of
The Disconnecting Circuit Breakers are type-tested according to class M2 and C2 of IEC 62271-108, a specific standard for combined switching devices. The Disconnecting Circuit Breaker for 145 kV has a three-pole operating mechanism with a common base (FG), and a single-pole operating mechanism on separate bases (FI) for 420 kV.
The CAOC only needs an energy storage capacitor to store pre-charge voltage with several kilovolts, and can generate a high voltage on a pulse capacitor after
The key obstacle in integrating high-voltage direct current (HVDC) point-to-point networks into meshed multiterminal HVDC networks (MTDC) is the absence of dc
