Patent

CA 2243466

The invention concerns a socket (1) in which a switching device (11) switches voltage from the supply side (3) through to the consumer side (4) only when a consumer (2) is provided. A measuring device (5), which is supplied with power, comprises a direct current test circuit (7) and an alternating current test circuit (8). Both test circuits attempt to pass measuring currents over a connected load. The alternating current test circuit (8) operates at higher frequencies than the mains frequency. An evaluation circuit (9) is designed to decide on the basis of predetermined criteria and measured values in a logical AND connection whether switch contacts of the switching device (11) are to be closed.

L'invention concerne une prise de courant (1) dans laquelle de la tension n'est commutée, à l'aide d'un dispositif de commutation (11), du côté alimentation (3), au côté consommateur (4), que lorsqu'un consommateur (2) est prévu. Un dispositif de mesure (5) alimenté en courant comporte un circuit de vérification du courant continu (7) et un circuit de vérification du courant alternatif (8). Les deux circuits de vérification essaient de piloter les courants mesurés sur une charge connectée. Le circuit de vérification du courant alternatif (8) fonctionne avec des fréquences plus élevées que la fréquence du secteur. Un circuit d'évaluation (9) est conçu pour décider, sur la base de critères prédéfinis et de valeurs mesurées en connexion logique ET, si les contacts de commutation du dispositif de commutation (11) doivent être fermés.
