Abstract (en)
[origin: EP1211706A1] The high tension circuit breaker includes two contact separating devices linked by a transmission mechanism. The mechanism includes a cam linkage, such that the two contact separating devices move at different speeds, the ratio of their two speeds changing during the course of the movement between an initial value of 0.5 and a maximum value of 1.2. The high tension circuit breaker comprises a first contact device (12) driven by a drive mechanism (14), and a tube (16) solidly attached to the first contact device. A second contact device (18) is mechanically linked to the tube by a transmission mechanism (20) with a cam (84). This linkage ensures a variable speed ratio (V2/V1) between the first and second contact devices. The ratio (V2/V1) is less than 0.5 when the first switch is close to its open position increasing to a maximum value of 1.2 near to the point of separation of the contacts, then reducing to 0.5 again.
