Abstract (en)

[origin: WO0042627A1] The invention relates to a high voltage circuit breaker, especially a gas-blast circuit breaker. Said high voltage circuit breaker has two switching contacts (1, 2) which face each other and which are surrounded by an insulating sleeve (5) when they are in their switching-on state, a screening electrode (6) being arranged coaxially in relation to said insulating sleeve. A first driveable switching contact (1) is connected to the second switching contact by the insulating sleeve (5) and a linkage mechanism, in such a way that when the first switching contact (1) is activated, said second switching contact moves in the opposite direction to the first switching contact (1). The screening electrode (6) is actively connected to the second switching contact (2) in such a way that it performs a movement controlling the electrical field in the contact gap (20) during a switching off operation.
