In medium voltage vacuum circuit breakers, in order to achieve an even distribution of force along the entire length drive shaft, mechanism is made per phase, that is, a separate electromagnet installed under each pole. The analysis designs and features operation breakers with phase electromagnetic carried out. Deficiencies these drives have been identified. design breaker kinematic diagram mon...
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 HVDC breaker. In overhead line systems under temporary faults, reclosing often required. However, once circuit breaker (DCCB) reclosed directly, large second overcurrent may occur whi...
