Definitions

  • the invention relates to a fault current module that can be assembled with circuit breakers of different rated currents in a modular design (FI / LS switch), the individual devices with their housings being arranged laterally and connected to form a compact unit, and mechanically coupled with one another with their switching and triggering mechanisms. and a connection can be established by means of an electrical conductor between a summation current transformer of the fault current module and connecting terminals of the circuit breakers.
  • FI / LS switch modular design
  • the invention is based on the object of designing the housing of the fault current module in a switch of the type mentioned at the outset such that the connection terminals can be assigned to either the upper or lower connection level of the switch using the same housing parts and only by a different arrangement of these parts, and thus a universally combinable combination between fault current module and line circuit breakers can be produced.
  • the invention is advantageous in that the housing of the fault current module can be easily assembled as required from a center body and two differently designed side bodies. that two variants of the residual current module are obtained with the same housing parts.
  • the two side bodies can be optionally connected to one another on the central body via symmetrically designed, clearly assigned housing contours.
  • the cohesion of the housing is achieved solely by positive locking and without additional connecting devices, because the shell-shaped ones are sufficient Housings used for cohesion and for closing used usual
  • Fig. 1 shows an open housing of the fault current module, but without its mechanical and electrical built-in parts, in a spatial representation, while in Fig. 2 the assembly of the housing according to FIG. 1 from middle and
  • FIG. 3 Side bodies is shown schematically.
  • the housing including the cover part is shown closed with side bodies exchanged with respect to FIGS. 1 and 2.
  • the housing 1 for the fault current module essentially consists of a shell-shaped central body 2 and two differently designed side bodies 3 and 4 arranged on both sides thereof, which are each made as molded parts from an insulating material.
  • the middle body 2 predominantly encloses the mechanism parts and the summation current transformer (not shown) of the residual current module, while the two side bodies comprise approximately the terminal block areas of conventional residual current circuit breakers or one or more circuit breakers (not shown) which can be arranged in the drawing plane.
  • the middle body 2 is in turn in the plane (drawing level) from one bowl-shaped lower part 2.1. a box-shaped intermediate part 2.2 arranged in the contact area and a likewise bowl-shaped cover part 2.3, which, however, also covers the width of the intermediate part in the base area of the housing 1 (FIG. 3).
  • a box-shaped intermediate part 2.2 arranged in the contact area and a likewise bowl-shaped cover part 2.3, which, however, also covers the width of the intermediate part in the base area of the housing 1 (FIG. 3).
  • the housing parts of the center body 2 can be assembled with one another via their outer housing contours and a plurality of centering members 2.4 designed as peg-shaped lugs or corresponding depressions in the plane of the drawing.
  • the lower part and cover part with their almost smooth outer sides 2.11 and 2.31, form the contact surfaces with neighboring switches, in particular with the line protection switches which can be arranged on one side.
  • the two outer sides thus limit the width of the fault current module, which normally comprises two so-called standard pole widths.
  • wider middle bodies and thus fault current modules for larger rated currents or several current paths can be produced, which then usually comprise three pole widths.
  • a side body 3 or 4 is attached to its two sides, which are designed such that they end flat on the outer sides 2.11, 2.31 with flush contours 2.5 of the housing (FIG. 3).

Abstract

Dans un disjoncteur à courant de fuite actionné par surintensité, monté en construction modulaire de série, le module à courant de fuite est disposé, avec son boîtier (1), latéralement par rapport à des disjoncteurs et est relié à ceux de manière à former une unité compacte. A cet effet, un assemblage est effectué entre un transformateur de courant de sommation dudit module à courant de fuite et les bornes de connexion des disjoncteurs, et leurs mécanismes de commutation et de déclenchement sont accouplés entre eux. Le raccordement électrique externe au module à courant de fuite s'effectue au moyen de bornes de connexion disposées dans un espace à bornes (3.1) du boîtier (1). Afin de pouvoir associer ce raccordement au module à courant de fuite, conformément aux données locales, au plan de raccordement, soit supérieur, soit inférieur de l'interrupteur, le boîtier (1) dudit module est monté de manière à former en un seul bloc une pièce centrale (2) en plusieurs parties et deux pièces latérales (3, 4) disposées de chaque côté sur toute la largeur du boîtier. Les deux pièces latérales (3, 4) sont réalisées différemment, la plus grande (3) comprenant l'espace (3.1) pour les bornes de connexion. Sur la pièce centrale (2) munie des profils de boîtier symétriques (2.5) peuvent être raccordées en alternant, si besoin est, les deux pièces latérales (3, 4), de manière à constituer un boîtier achevé (1) groupant tous les composants du module. Le module à courant de fuite peut être ainsi combiné de façon universelle avec des disjoncteurs, pour former des disjoncteurs à courant de fuite actionnés par surintensité, à courant nominal différent.
