Definitions

  • the invention relates to a protective switching device, designed for multi-pole tripping, when a series of further protective switching devices are connected, by a driver.
  • Circuit breakers for multi-pole tripping are available in a wide variety of designs:
  • the switch locks usually work with a fixed latch, which becomes complex when they are to be used in conjunction with devices in series that automatically switch to a switched-off state, as is the case with residual current circuit breakers and undervoltage releases.
  • the multi-pole release is passed on via a wire pin, which is fixed in the release lever.
  • a wire pin which is fixed in the release lever.
  • the invention is based on the object of developing a protective switching device for multi-pole tripping which can work with comparatively few parts, can be manufactured in a highly mechanized manner and satisfies high technical requirements during operation.
  • the described object is achieved by a protective switching device according to claim 1.
  • the driver forms a double eccentric according to its function, one of which is acted upon by a pawl when it drops from a release lever as a result of a release by a working movement of the pawl.
  • the other eccentric moves follow his working movement by releasing the release lever.
  • the release lever is in this case mounted in a stationary manner and the pawl can be moved by storing a coupling rod to a manual control element in its portable pawl bearing.
  • Such a structure is the basis for the corresponding direction of rotation of the components of the key switch. This direction of rotation can correspond to the opening direction of a movable contact, so that one can work in the kinematics without a converter. This enables a simple and clear structure. In particular, you do not need a link guide, thus reducing the friction and can achieve a compact and fast circuit breaker.
  • the movable contact arm is supported on the fixed bearing of the release lever in the open position of the manual control element, the latching point between the pawl and release lever forming a triangular arrangement with the fixed bearing of the release lever and the portable bearing for the contact arm.
  • the pawl, driver and release lever have the same direction of rotation when unlatching.
  • the bearing for the contact arm on the pawl is advantageously connected to the fixed bearing of the release lever by coupling means. This arrangement results in a simple and inexpensive switch lock for common direction of rotation without a converter. It is advantageous to provide the pawl bearing within the triangular arrangement.
  • the driver is arranged to form protective switching devices outside the geometrical locations of the coupling rod, pawl and release lever.
  • This enables coupling to many types of protective circuit Devices with a different geometry for their kinematics, as is common with miniature circuit breakers.
  • Protective switching devices of the so-called high-current series can also be connected. It is possible and advantageous to arrange the driver on a fixed bearing. In combination with the portable bearing of the release lever and the portable bearing of the pawl, this simplifies the construction of the overall arrangement.
  • a thermal release can act with its moving part on the release lever outside the triangular arrangement in the same direction of movement as a magnetic release to be provided.
  • the plunger of the magnetic release directly engages the release lever.
  • the thermal release is advantageously allowed to engage the release lever with a pull handle.
  • FIG. 1 shows a protective switching device in an indicated housing with a switch lock, a pair of contacts, a pivotable manual control element and a driver in the switched-on position.
  • FIG. 2 the representation of FIG. 1 shows the transmission of the unlatching via the driver to protective circuit devices in a row.
  • FIG. 3 illustrates how, as a result of the unlatching of a neighboring protective switching device via the driver, the protective switching device is released.
  • 4 shows essential components from the arrangements according to FIGS. 1 to 3 in the manner of an exploded view.
  • the protective switching device 1 according to FIG. 1 is designed for multi-pole tripping in the case of a series of further protective switching devices.
  • the coupling is provided by a driver 2 with a fixed bearing 19.
  • the driver forms a function according to a double eccentric: the one eccentric 3 is acted upon by a pawl 5 when it falls off by a release lever 6 when the release lever is released from the release lever.
  • Another eccentric 4 of the driver 2 acts on the release lever 6 in a unlatching manner if the driver is moved counterclockwise as a result of the unlatching of a protective switching device. This counterclockwise rotation is common to all the essential components of the switch lock and a movable contact arm 7.

Abstract

L'invention concerne une unité coupe-circuit (1), conçue pour un déclenchement multipolaire lors de l'adjonction d'autres unités coupe-circuit, par l'intermédiaire d'un élément d'entraînement (2). Ce dernier (2), selon sa fonction, forme un double excentrique. L'un (3) des excentriques est sollicité par un cliquet (5) lorsque ce dernier est relâché par un levier de déclenchement (6) à la suite d'un déverrouillage par l'intermédiaire d'une course de travail du cliquet. L'autre excentrique (4), à la suite de sa course de travail, est déplacé de manière à déverrouiller le levier de déclenchement (6). Ce dernier (6) est monté de manière fixe (8) et le cliquet (5) est monté de manière mobile. A cet effet, une tige d'accouplement (10) destinée à un organe de commande manuelle (11) est montée dans le palier mobile (9) du cliquet.
