Definitions

  • the present invention relates to a magnetic chamber for a low-voltage electromagnetic switching device, in particular a Kompaktharistarter, which usually has two magnetic drives, each magnetic drive actuates a main slide.
  • the internal circuit is designed so that each magnetic drive is assigned a different motor running direction.
  • the invention relates to a low-voltage electromagnetic switching device, in particular a compact turnaround starter having two magnetic drives, each magnetic drive actuates a main slide.
  • a Wendever- locking is implemented for the load feeders in a single installation outside of the device.
  • Two contactors are wired in parallel and a circuit breaker is connected in series.
  • the lock is realized by additional parts, such as an armature and a bearing, which are mounted between the contactor drives and which act on the contact piece carrier.
  • the lock acts on the armatures of the contactor drives for mutual blocking. That is, the reversing lock for mutual locking of the main drives prevents the simultaneous closing of the main contacts to change the direction of rotation.
  • an electric reversing contactor that has a mechanical locking for the movable anchor parts of the two contactor drives.
  • the electric reversing contactor has a housing in which two cavities are provided, each having a system of switching parts with their own electromechanical control. That is, the Magnetic drive of one system is arranged separately from the magnetic drive of the other system. For each magnetic drive a separate magnetic chamber is provided. Between the two cavities, a movable locking part is provided, which prevents a simultaneous displacement of the movable contact carriers, which are coupled to the movable arm parts, of the two magnetic drives.
  • a disadvantage of such an electrical reversing contactor are the complicated structure of the mechanical locking and the indirect locking of the magnetic drives. Furthermore, such an electrical reversing contactor is relatively large in its outer dimensions, since two separate magnetic chambers are provided in the housing of the electric reversing contactor.
  • the object of the invention is to provide a magnetic chamber for a low-voltage electromagnetic switching device or a low-voltage electromagnetic switching device, which are very simple and compact and which allows a simple mechanical locking of one of two magnetic drives, while the other magnetic drive is operable.
  • a simple and direct mechanical locking of a main slide of a magnetic drive is to be made possible when the other magnetic drive is in operation.
  • the object is achieved by a magnetic chamber for a low-voltage electromagnetic switching device, in particular a Kompaktharistarter having two magnetic drives, each magnetic drive actuates a main spool, wherein the magnetic chamber for receiving both magnetic drives of the electromagnetic low-voltage switching device is formed and one movable held mechanical Wendeverriegelung for alternating mechanical locking of one of the two magnetic drives is arranged in the magnetic chamber, wherein the mechanical lock acts on both main slide solved.

  • the core of the invention is that the movably held mechanical turning lock is arranged directly in the magnet chamber and that the magnet chamber is designed to accommodate both magnet drives.
  • a magnetic chamber allows the direct locking of a magnetic drive arranged in the magnetic chamber, in particular a main slide of a magnetic drive, while the other magnetic drive is released for operation.
  • the movably held mechanical reversible locking locks the one, sometimes the other magnetic drive.
  • the mechanical turning lock is provided directly in the magnetic chamber, which surrounds both the one and the other magnetic drive.
  • the magnetic chamber comprises both magnetic drives
  • a low-voltage electromagnetic switching device in which such a magnetic chamber is provided, can be made very compact.
  • the mechanical Wendeverriegelung can act through such a magnetic chamber directly on one of the main slide one of the magnetic drives, which opens and closes the main contacts of the magnetic drive, ie lock this in its movement.
  • the blocking of a magnetic drive functions in that a part of the mechanical turning lock engages in a main slide of a magnetic drive, thereby preventing a displacement of the main slide.
  • the movably held mechanical turning lock is arranged in the magnet chamber. That is, there is only one common magnetic chamber for both magnetic drives. For locking the magnetic drives, the mechanical turning lock is therefore also provided in the one magnetic chamber.
  • the mechanical Wendeverriegelung advantageously sits between the two magnetic drives.
  • a magnetic chamber in which the mechanical turning lock is formed as a turning anchor held pivotable about an axis, wherein the axis is provided in a wall of the magnetic chamber.
  • the Wendeanker also as
  • Turning designated can be rotated about the axis, so as to block either one or the other magnetic drive.
  • the axis to which the turning armature is attached is preferably arranged in the wall of the magnetic chamber. As a result, the turning armature sits directly on the magnetic drives in order to release or block them. As a result of this integration of the axis or of the turning armature into the wall of the magnet chamber, the magnet chamber and thus the low-voltage electromagnetic switching device in which the magnet chamber is used can be made compact.
  • the magnetic chamber is designed such that it allows the guidance of the respective main slide and the magnetic drives. That is to say, the magnet chamber has, at least in regions, an intermediate wall on whose two walls the two magnet drives, i. the main pushers are guided. At this intermediate wall, the movably held mechanical Wendeverriegelung, in particular the turning armature is arranged.
  • the object is achieved by a low-voltage electromagnetic switching device, in particular by a compact reversing starter, the two has different directions current magnetic drives, wherein each magnetic drive actuates a main slide, and wherein both magnetic drives are arranged in a formed according to the first aspect of the invention, the magnet chamber, wherein the movably held mechanical turning lock depending on their position with a main slide of one of the magnet drives is engaged to fix this, solved.
  • An electromagnetic low-voltage switching device with such a magnetic chamber can be constructed very compact and simple.
  • the mechanical turning lock also works in the event of a power failure. Due to the direct locking of the main slide, any errors in the magnetic drives have no influence on the safety chain. The fact that the mechanical turning lock always blocks one of the main slides in its movement means that it can not happen that both magnetic drives can be operated simultaneously.
  • each main slide of each magnetic drive on its side facing the mechanical turning lock side has a correspondingly pronounced contour, in particular a groove, a recess or a bore, for engaging the mechanical Wendeverriegelung.
  • the mechanical turning lock engages in the contour, for example in the groove, the recess or the bore, of a main slide and thus prevents movement of this main slide.
  • the mechanical turning lock is designed as a turning anchor or turning heart.
  • a turning anchor or a turning heart has an approximately T-shaped form. The ends of the transverse T-
  • the electromagnetic low-voltage switching device has a microcontroller for controlling the drive units of the magnetic drives or the turning lock. That is, the electrical control of the turning lock can be realized by the same microcontroller, which is also designed for the control of both magnetic drives. The control of the reversible locking takes place in particular via the magnetic drives. As a result, hardware can be saved and the low-voltage electromagnetic switching device can be dimensioned small.
  • the magnetic drives are designed as contactor drives.
  • the reversing lock for mutual blocking of the contactor drives prevents the simultaneous closing of the main contacts to change the direction of rotation of the contactor drives.
  • the technical solution is realized by the turning armature or the turning heart, which blocks the main slide of the respective contactor drives to close the contacts. The effect of the turning armature is directly on the main slide, which open and close the main contacts of the respective contactor drives.
