  • Medium and high-voltage electric switch with return on closure and an insertion device for inserting a resistance
    Patent number: 8952285
    Abstract: An electric switch for application to high- and very high-voltage circuit breakers and switches comprising a flexible toroidal helical spring (8) placed in a groove of a control rod (1) carrying a movable resistance-insertion contact (2), and springs (4) placed about the movable resistance-insertion contact to cause the springs to be compressed until a certain value is reached, at which value the movable resistance-insertion contact causes the flexible toroidal helical spring (8) to deform under pressure enabling the movable resistance-insertion contact (2) to be withdrawn. Among other uses, the switch is suitable for use in a resistance-inserting device that does not need additional mechanical moving parts. For application to high- and very high-voltage circuit breakers and switches.

  • Circuit breaker with two aligned breaker chambers, a common transmission, and reduced size
    Patent number: 8653395
    Abstract: A very high voltage circuit breaker comprising, for each phase, at least two breaker chambers aligned with each other, each chamber including a pair of main contacts, a pair of arcing contacts that are stationary relative to the main contacts, and a nozzle for blowing out hot gases resulting from the breaking operations, the pairs of contacts being partly of complementary male and female forms, each comprising at least one movable contact, the nozzle being stationary relative to the movable main contact and arcing contact.
