Definitions

  • the present invention relates to an electrical switch device comprising in particular a device for compensating for wear of the contacts.
  • a switch-type electrical apparatus, circuit breaker or contactor-circuit breaker typically has, on each power pole, separable movable contacts of fixed contacts, actuated in motion by means of an electromagnet to switch an electric charge to be controlled.
  • This electromagnet generally comprises a fixed yoke and an armature which is movable relative to the fixed yoke, thus forming a magnetic circuit having a variable gap.
  • the electromagnet also has an electromagnetic excitation coil in which can circulate an excitation current which then creates a magnetic field causing a displacement of the movable armature relative to the fixed yoke.

  • the wear-compensating device of the contacts comprises notches for marking different positions of the abutment piece as the wear of the contacts increases.
  • the automatic wear-compensating device comprises stacked lamellae capable of interposing with the wear of the contacts between the abutment piece and a fixed armature.
  • the slats can be inserted by a spring or actuated by a magnet.
  • the contact wear compensating device comprises hydraulic or pneumatic compensation means between the abutment piece and a fixed armature.
