Abstract (en)
[origin: WO2008043721A1] An insulation tube (18), provided between the main contacts (12b, 14b) and the arcing contacts 5 (12a, 14a) of an interrupter tube (10) in a high- or medium-voltage circuit breaker, is used for modifying the distribution of equipotential lines (V) during a power cut-off. It is thus possible to decrease the electric field on the contacts and to improve 10 the cut-off as well as the dielectric behaviour in open position. The insulation tube (18) can also be used for transmitting movement between the contacts (12, 14) in order to trigger the circuit-breaker.
