Description

La présente demande a pour objet un procédé de fabrication d'un appareil électrique modulaire assurant au moins deux fonctions électriques, de préférence d'un disjoncteur différentiel modulaire.The present application relates to a method of manufacturing a modular electrical appliance providing at least two electrical functions, preferably a modular differential circuit breaker.

Les appareils électriques modulaires ainsi que les disjoncteurs de ce type peuvent comprendre au moins un compartiment de coupure et un compartiment de protection différentielle, le ou les compartiment(s) de coupure présentant un mécanisme d'ouverture et de fermeture d'au moins un contact électrique entre une ligne électrique amont et une ligne électrique aval. Le compartiment de protection différentielle peut comprendre un détecteur de défaut différentiel comportant un tore et un circuit de détection. Le compartiment de protection différentielle peut en outre comprendre un circuit test comportant un bouton test.Modular electrical devices and circuit breakers of this type may comprise at least one breaking compartment and a differential protection compartment, the at least one compartment (s) having a mechanism for opening and closing at least one contact between an upstream power line and a downstream power line. The differential protection compartment may comprise a differential fault detector comprising a toroid and a detection circuit. The differential protection compartment may further comprise a test circuit comprising a test button.

Le principe de fonctionnement d'un disjoncteur différentiel est de comparer les intensités sur différents conducteurs qui le traversent. Pour le cas d'un disjoncteur différentiel monophasé, celui-ci compare l'intensité du courant circulant dans un conducteur correspondant à la phase, et l'intensité du courant circulant dans un conducteur correspondant au neutre. Autrement dit le disjoncteur différentiel vérifie que la somme des intensités du courant circulant dans le conducteur correspondant à la phase et le conducteur correspondant au neutre s'annulent. Pour le cas d'un disjoncteur différentiel multiphasé, le disjoncteur différentiel vérifie que la somme des intensités du courant circulant dans les conducteurs correspondant aux phases et au neutre s'annule.The operating principle of a differential circuit breaker is to compare the intensities on different conductors that cross it. For the case of a single-phase differential circuit breaker, it compares the intensity of the current flowing in a conductor corresponding to the phase, and the intensity of the current flowing in a conductor corresponding to the neutral. In other words, the differential circuit breaker verifies that the sum of the intensities of the current flowing in the conductor corresponding to the phase and the conductor corresponding to the neutral are canceled. In the case of a multiphase differential circuit breaker, the differential circuit breaker verifies that the sum of the currents of current flowing in the conductors corresponding to the phases and to the neutral is canceled.

Le dispositif différentiel est donc basé sur le principe que, dans une installation normale, le courant électrique qui arrive par un conducteur doit ressortir par un autre. Dans une installation monophasée, si le courant dans le conducteur correspondant à la phase au départ d'un circuit électrique est différent de celui dans le conducteur correspondant au neutre, c'est qu'il y a une fuite.The differential device is thus based on the principle that, in a normal installation, the electric current that arrives from one conductor must come out through another. In a single-phase installation, if the current in the conductor corresponding to the phase at the start of an electrical circuit is different from that in the conductor corresponding to the neutral, it is that there is a leak.

A cet effet, chaque conducteur passe dans le tore, chacun de ces conducteurs formant ainsi des champs électromagnétiques identiques et en opposition qui s'annulent. En cas de différence entre les champs électromagnétiques, le champ électromagnétique résultant actionne compartiment de coupure qui coupe rapidement le courant en ouvrant le contact électrique.For this purpose, each conductor passes into the torus, each of these conductors thus forming identical and opposing electromagnetic fields that cancel each other out. If there is a difference between the electromagnetic fields, the resulting electromagnetic field operates switch compartment which cuts off the current quickly by opening the electrical contact.

Les disjoncteurs différentiels actuels sont d'abord assemblés en leur totalité et réglé ainsi que contrôlé à la suite de l'assemblage. En cas de problèmes liés au réglage et/ou au contrôle le produit est jeté car difficile à démonter.Current differential circuit breakers are first assembled in their entirety and adjusted and controlled as a result of assembly. In case of problems related to adjustment and / or control the product is thrown because difficult to disassemble.
