HIGH-VOLTAGE DISCONNECTING CIRCUIT BREAKER AND METHOD OF OPERATING THE SAME
摘要
A high-voltage disconnecting circuit breaker comprises a first and a second contact; means provided for moving the contacts to a first mutual distance; and means provided for quenching any arc appearing between the contacts during said movement to thereby provide the functionality of a high-voltage circuit breaker, wherein the means provided for moving is further provided for moving the contacts to a second mutual distance larger than the first mutual distance after quenching of any arc to thereby provide the voltage withstand functionality of a high-voltage disconnector.
