  • High tension circuit breaker having varistors
    Patent number: 5124872
    Abstract: A high tension circuit breaker comprising at least one circuit-breaking chamber and, in parallel with the circuit-breaking chamber, firstly a varistor in series with an interrupter, and secondly a tension-distributing capacitor. The circuit breaker has a linear resistor having a resistance lying in the range range 30 ohms to 300 ohms inserted in series with the varistor. The invention is particularly suitable for reactance circuit breakers.

  • Cut-off chamber of a lightning protector
    Patent number: 4058848
    Abstract: Cut-off chamber of a lightning protector, characterized in that on the one hand, it comprises a wall made of a porous ceramic substance, ensuring the discharge and the cooling of the gases at the periphery of the chamber, at the time of the ignition of an arc between two elctrodes combined in that chamber and that on the other hand, a means for reinforcing the dielectric strength of the wall is arranged perpendicular to the zones subjected to the highest potential gradients.
