摘要：
Disclosed is a wheeled circuit interrupter (1) provided with a blower-attenuator for cooling and deionizing a switching gas coming from an arc quenching chamber (3). The blower-attenuator (5) consists of two bodies (6, 7) telescopically fitting into each other, one (6) of which is stationary and the other has a tight surface (10) bearing against an outlet surface (4) of the arc quenching chamber (3). Owing to the two-piece design of the blower-attenuator, the tightness between said blower-attenuator and the arc quenching chambers (3) is improved by the gas pressure.
