Definitions

  • the invention relates to a low-voltage circuit breaker with a rated current plug, with an electronic trip unit of the circuit breaker is adapted to the conditions of its place of use, wherein when using an unsuitable rated power plug by an evaluation of the trip unit setting to minimum settings and by means of a message device is a message.
  • Circuit-breakers in the low-voltage range should be installed in as wide a nominal current range as possible, eg. B. 200 A to 6300 A, can be used. Your rated current should therefore be selectable. By setting a specific rated current, the respective overcurrent release is parameterized to a selected nominal current. The overcurrent release can thus be constructed the same for the entire nominal current range.
  • Such a rated current plug is known for example from US-A 4,649,455. If the rated current plug is removed from the switch after this solution, eg. B. against a rated current plug with changed settings the trip unit automatically adjusts itself to a minimum tripping value until a rated current plug has been used again. In the simplest case, this is achieved in that a setting resistor, which is electrically connected in parallel to the adjustment resistors in the rated current plug, is fixedly arranged in the trip unit and determines the rated current when removing the rated current plug.
  • DE-A 198 45 825 also discloses a solution according to which electrical coding is used so that unsuitable characteristic values of the rated current plug do not lead to their being transmitted to the trip unit, but that in an attempt to use such a rated current plug Message is sent.
  • the signaling device should be arranged on the rated current plug. An error message only occurs if the rated current plug is inserted. Errors such as missing contact connection between rated current plug and trip unit or a generally missing rated current plug can not be displayed in this way.
  • the invention has for its object to further increase the safety of circuit breakers with respect to the use and function of the circuit breaker suitable rated current plug and have to go to the expense of mechanical coding.
  • the signaling device is arranged on the housing of the low-voltage circuit breaker or on the trip unit.
  • the signaling device can in the same way as in DE-A 198 45 825 shown an acoustic and / or optical signal generator, for. B. a flashing light-emitting diode.
  • a circuit 12 is monitored, so that in the case of impermissible current values via contacts 2, actuated by a drive device 3, an elimination occurs.
  • the current in the electric circuit 12 is measured with a current sensor 4. Its measured value is processed in a tripping unit 5.
  • the trip unit 5 consists of a microprocessor 6, a reading device 7 and a Evaluation 8.
  • the rated current plug 9 contains the coding for the rated current and optionally other values, in the simplest case in the form of resistors defined size.
  • the values read in by the reading device 7 are compared with the permissible values of the affected circuit breaker 1. If these are within permissible limits, they are taken over by the trip unit 5. If, on the other hand, there are no permissible values, because, for example, the rated current plug 9 has been removed, a pulsating signal is given to an LED 10 by the tripping unit 5. The LED 10 then flashes and notifies the user of a fault condition. At the same time, the set values of the trip unit 5 are changed to minimum values. The message and the minimization of the setting values remain effective until a permissible rated current plug has been inserted again.
  • a signaling device can also be integrated directly into the tripping unit 5.

Abstract

Un calibreur est généralement équipé d'un codage électrique, de manière à empêcher la transmission de valeurs caractéristiques incorrectes du calibreur à l'unité de déclenchement et à entraîner l'émission d'un signal lors d'une tentative d'utilisation dudit calibreur. Selon la présente invention, le dispositif de signalisation est agencé sur le boîtier du disjoncteur basse tension (1) ou sur l'unité de déclenchement (5). Ainsi, par rapport à la solution classique, les états 'calibreur incorrect', 'liaison de contact défectueuse', 'calibreur défectueux' sont également détectés.

Claims (4)

  1. Disjoncteur basse tension (1) équipé d'un calibreur (9) par lequel une unité de déclenchement (5) électronique du disjoncteur (1) peut être adaptée aux conditions de son lieu d'utilisation, un réglage à des valeurs de réglage minimales étant effectué par un équipement d'analyse (8) de l'unité de déclenchement (5) lors de l'utilisation d'un calibreur (9) inapproprié, et un message intervenant au moyen d'un équipement de signalisation,
    caractérisé en ce que l'équipement de signalisation est disposé sur le boîtier du disjoncteur basse tension (1) ou sur l'unité de déclenchement (5).
  2. Disjoncteur basse tension (1) selon la revendication 1, caractérisé en ce que l'équipement de signalisation est un émetteur de signaux acoustique et/ou optique.
  3. Disjoncteur basse tension selon la revendication 1 ou 2, caractérisé en ce que l'équipement de signalisation est une diode émettrice de lumière (10) clignotante.
  4. Disjoncteur basse tension selon une des revendications 1 à 3, caractérisé en ce que, en l'absence de valeurs de réglage appropriées pour le disjoncteur basse tension (1) concerné sur les lignes d'entrée de la connexion enfichable avec le calibreur (9), un signal d'actionnement de l'équipement de signalisation est envoyé par l'équipement d'analyse (8) de l'unité de déclenchement (5).
