|1. (WO2018041874) A HIGH VOLTAGE CIRCUIT BREAKER|
|Applicants:||ABB SCHWEIZ AG
|Title:||A HIGH VOLTAGE CIRCUIT BREAKER|
The present invention relates to a high voltage circuit breaker comprising first and second interrupter units(42, 44) located in a high voltage region, each interrupter unit including a movable contact (3b; 43b) arranged movable between an opened and closed state, and an operating mechanism (46) located in the high voltage region and arranged to move the movable contacts (3b; 43b) between the opened and closed states. The operating mechanism comprises a first actuator (48) arranged to operate the movable contact (3b) of the first interrupter unit (42), and a second actuator (50) arranged to operate the movable contact (43b) of the second interrupter unit (44), and the first and second actuators are configured to move the movable contacts of the first and second interrupter units (42, 44) independently of each other. The high voltage circuit breaker comprises a power supply source(19) located in aground region, and a power transfer arrangement for transferring power from the power supply source(19) to the operating mechanism (46) comprising a wireless power transfer device (25) adapted for wireless power transmission between the ground region and the high voltage region. The first and second actuators (48, 50) are integrated in one single unit (51) disposed between the first and second interrupter units, and said power transfer device (25) is configured to supply the first and second actuators with power.
