Abstract (en)
[origin: WO2011070022A1] The high-voltage circuit breaker makes it possible to reduce the electric field on the arc contacts during cut-offs and consequently the rate of triggering the apparatus. The two contacts (2) and (6) are able to move relative to each other in opposite directions during cut-offs. Their respective supporting members (8) and (16) are also able to move and slide one in relation to the other with respect to a fixed frame. A screen (1) is placed inside the support housing for the first contact (6), by virtue of springs (17), and is moved during an opening operation by means of rods (31). The stops (30) define the instant when the screen starts to move. During its movement, the screen compresses the springs (17) and it keeps this position relative to the arc contact (2) and to the permanent contact (20) until the end of travel. Application to very high-voltage circuit breakers.
