  • the invention more particularly relates to a circuit breaker or disconnector for which the drive of the secondary movable contact is optimized to limit the stroke and optimize the acceleration of the secondary movable contact during an opening phase of the apparatus.
  • a circuit breaker with double contact movement has two contacts that are able to move relative to one another and with respect to a fixed structure, during a circuit opening or closing phase.
  • one of the two movable contacts is driven by a drive mechanism, and it drives the other moving contact, commonly called secondary mobile contact, via a return mechanism.
  • This return mechanism is generally designed so that the displacement of the secondary movable contact is simultaneous and opposite to the displacement of the main movable contact.
  • EP-A-1933348 and EP-A-0809269 each describe a dual-contact disconnector which comprises a system comprising two connecting rods and a central return member through which the main movable contact drives the secondary movable contact.
  • the main movable contact and the secondary movable contact move simultaneously in opposite directions.
  • the drive mechanism of the moving contact must therefore be capable of producing sufficient energy to move the two moving contacts simultaneously. This energy is therefore relatively important at the beginning of the opening phase of the disconnector.
  • the drive mechanism provides an energy that allows the moving contacts to quickly reach a sufficiently high speed for breaking an electric arc formed between the two movable contacts.
  • the dimensions of the components of the drive mechanism, the movable contacts and the return mechanism are relatively large to withstand the forces involved when opening or closing the disconnector.
