Definitions

  • the invention relates to the field of actuation by single control of the movable contacts of two interrupt units. More specifically, the actuation of the breaking chamber and the vacuum interrupter of a hybrid circuit breaker is carried out according to the invention via a single mechanical arrangement, although the moving contacts of each of the switches follow. their own profile of movement in time, and in particular that the vacuum bulb is protected when opening the interrupting chamber.
  • the invention relates to a hybrid circuit breaker whose means for actuating the movable contacts allow a simultaneous opening of the breaking chamber and vacuum bulb followed by a closure of the bulb anticipated with respect to the return to service of the breaking room.
  • a hybrid type switch device cooperates two different cutoff techniques. Such a mixed cutoff applies in particular for a switch device for high and medium voltage which comprises an empty dielectric gas switch, also called “vacuum bulb”, and a switch containing a dielectric gas, called “breaking chamber”.
  • Each of the switches comprises a pair of moving arcing contacts between a closed current passage position and an open position. Actuating means allow the movement of the contacts.
  • the simplest arrangement is a longitudinal alignment of the pairs of contacts, a shaft allowing separation of the contacts of the vacuum interrupter simultaneous with the separation of the contacts of the gas switch, sometimes slightly offset from the control signal opening, as described in FR-A-2 840 729.

  • the actuating means are provided with delaying means making it possible to fulfill the function of opening the vacuum interrupter a few milliseconds from that of the interrupting chamber, preferably 3 ms after the tripping control of the circuit breaker.

  • the separations between the opening times of the vacuum bottle 20 and the breaking chamber 10, are substantially synchronized, that is to say that the contacts 11, 12 and 21, 22 separate at the same time. It is preferable that the contacts 21, 22 of the vacuum interrupter 20 open slightly after the emission of the trip control signal at time t 0 , after a latency time of a few milliseconds, and advantageously, after the dead travel of the gas switch 10.
  • this opening time offset is of the order of 3 ms; however, depending on the power of the circuit breaker and the dielectric gas used in the breaking chamber 10, this offset can take a different value. Thanks to the actuating means according to the invention, it is easy to make this adjustment, as will be explained later.
