Definitions

  • the invention relates to an electromagnetic Current release for an electrical circuit breaker with a Magnetic coil, a movable armature and a fixed magnetic core, through a power connector on the solenoid is held.
  • Generic electromagnetic current release according to FIG. 2 are used to detect overcurrents, especially short-circuit currents, with conventional electrical circuit breakers applied to single and multi-pole electrical consumers to protect against impermissible operating conditions.
  • This Circuit breakers can be circuit breakers, motor circuit breakers and circuit breakers. You must have overcurrents ever according to the applicable regulation within certain response limits switch off.
  • the current releases are included coupled to the contacts of the circuit breaker to be opened, that they respond to an overcurrent or Open short-circuit current and keep open if necessary.
  • 2 are such current release 1 from a magnetic coil 2, a coil frame 3 with a guide tube 4, a movable anchor 5, a stationary magnetic core 6, a spring 7 and one Power connector 8 assembled.
  • the bobbin stand 3 with the guide tube 4 is made of insulating material.
  • the magnet coil 2 is wound or attached.
  • the one movably mounted in the guide tube 4 Armature 5 moves against the spring force of the spring 7 as Response to an overcurrent or short circuit current.
  • a magnetic core 6 is pressed.
  • the magnetic core 6 is an additional part, which is preferably is stored inside the guide tube 4, i.e. at least partly inside the magnetic coil 2.
  • the invention has for its object an electromagnetic Current triggers of the above-mentioned type are partially minimized and therefore economical to manufacture.
  • the object is achieved in that the magnetic core and the Power connector are made in one piece.
  • a particularly inexpensive embodiment is given if the magnetic core and the power connector as one piece Stamped and bent part are manufactured.
  • the electromagnetic current release 1 is off a magnetic coil 2, a coil frame 3 with a guide tube 4 made of insulating material, a movable anchor 5, a stationary magnetic core 6, a spring 7 and one Power connector 8 composed as essential elements.
  • the magnet coil 2 is wound around the coil frame or attached to it and part of the current path of a consumer to be protected.
  • the armature 5 is movable stored in the guide tube 4 and responds to a short circuit current. The movement of the armature 5 brings about corresponding mechanical coupling elements an opening in the current path located contact points.
  • the anchor moves 5 against the action of force also in the guide tube 4 mounted spring 7.
  • a fixed magnetic core 6 arranged together with a power terminal 8 for the solenoid 2 is manufactured as a one-piece part. This part is advantageous executed as a stamped and bent part.

Abstract

L'invention concerne un déclencheur de courant électromagnétique (1), dans lequel un noyau magnétique fixe (6) faisant partie du système magnétique est réalisé d'une seule pièce avec une borne (8) servant au raccordement de la bobine magnétique (2) du système magnétique, sous la forme d'une pièce estampée-cintrée. On obtient ainsi un déclencheur de courant électromagnétique économique.
