Actuator Circuit Breaker
This work used an available piezoelectric actuators. Contact opening speedsare assessed is characterized under this operating regime. This could permit direct actuation using a piezoelectric actuator. The stroke of the actuator studied here is in the right order of magnitude
The arc control on the contacts is critical for
- a successful current interruption 10,000-100,000 A.
- in low voltage 250 Volts devices
