Abstract (en)
[origin: EP0430123A1] The invention relates to a high-voltage circuit breaker. <??>The subject is a high-voltage circuit breaker comprising at least one cutoff chamber (1, 2) and, in parallel with this cutoff chamber, on the one hand a varistor (V1, V2) in series with a switch (I1, I2) and, on the other hand, a distributing capacitor (C1, C2), characterised in that a purely ohmic resistor (R1, R2), of value lying between 30 and 300 ohms, is inserted in series with the said varistor (V1, V2). <??>Application in particular to reactance circuit breakers. <IMAGE>
