Title (EN) A SAFETY DEVICE FOR A POWER SUPPLY OR APPLIANCE COUPLED THERETO
(FR) DISPOSITIF DE SÉCURITÉ POUR UNE ALIMENTATION ÉLECTRIQUE OU UN APPAREIL ÉLECTRIQUE COUPLÉ À CELLE-CI
Abstract:
(EN) Safety device for an electrical apparatus powered by an AC mains power supply, the safety device comprising: an electric circuit having inputs for connecting to an active, neutral and earth conductors of the electrical apparatus which are in turn coupled to the AC mains power supply, the circuit being operable to: produce and apply a stepped down voltage and current to the earth conductor from the main supply; and electrically isolate the active and neutral conductors from the earth conductor in response to detecting that either: the active conductor is incorrectly wired to the neutral circuit of the AC mains power supply; the neutral conductor is incorrectly wired to the active circuit of the AC mains power supply; or the neutral conductor is switched; wherein one or more solid state relays are employed by the circuit for both producing the stepped down voltage and electrically isolating the conductors from earth.
(FR) L'invention concerne un dispositif de sécurité pour un appareil électrique alimenté par une alimentation électrique en courant alternatif, le dispositif de sécurité comprenant : un circuit électrique ayant des entrées pour une connexion à un conducteur actif, un conducteur neutre et un conducteur à la terre de l'appareil électrique qui à leur tour sont couplés à l'alimentation électrique en courant alternatif, le circuit pouvant être mis en œuvre pour : produire et appliquer une tension abaissée et un courant au conducteur à la terre de l'alimentation principale ; et isoler électriquement les conducteurs actif et neutre depuis le conducteur à la terre en réponse à la détection de l'une ou l'autre des situations suivantes : le conducteur actif est incorrectement câblé au circuit neutre de l'alimentation électrique en courant alternatif ; le conducteur neutre est incorrectement câblé au circuit actif de l'alimentation électrique en courant alternatif ; ou le conducteur neutre est commuté ; un ou plusieurs relais transistorisés étant utilisés par le circuit à la fois pour produire la tension abaissée et pour isoler électriquement les conducteurs de la terre.
