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).
- the somewhat larger side body 3 forms a box-shaped terminal space 3.1 in its upper area for receiving a plurality of connection terminals (not shown), while an exchangeably inserted insulating and sealing part 3.2 is arranged in its lower area.
- line feeds, not shown, of the summation current transformer to the line circuit breakers arranged behind them in the drawing plane can be inserted with the correct orientation in such a way that a fixed mutual association of side body 3 and summation current transformer can be produced.
- the opposite side body 4 preferably receives additional terminals, not shown, which are independent of the later attachment of the Side body on the middle body can already be mounted in position beforehand.
- a second connection point results between recesses 2.7 in the lower part 2.1 and recesses in the cover part 2.3 (not visible), to which hook-shaped projections 3.4 and 4.4 are assigned in the side bodies . These are each arranged in pairs and point with their hook contour in the direction of lower part 2.1 or cover part 2.3.
- the recesses 2.7 and the hook-shaped approaches are each arranged in pairs and point with their hook contour in the direction of lower part 2.1 or cover part 2.3.
- the housing is assembled by first of all the shell-shaped lower part 2.1 and the box-shaped intermediate part 2.2 together with the associated inputs. Components are assembled, as shown in FIG. 2.
- the centering links are assembled, as shown in FIG. 2.
- the cover part 2.3 can be put on, as shown in FIG. 3.
- the side parts 3, 4 are shown interchanged with one another, and the insulating and closing part 3.2, which is only open on one side towards the outside 2.11, is rotated by 180 ° and inserted correctly, so that the cable leads of the summation current transformer are always on the outside 2.31 of the cover part are covered.
- conventional connecting means such as screws or rivets, are introduced into the peg-shaped depressions of the centering members 2.4, which connect the lower part and the cover part and thus close the housing 1 in a functional manner.
- the two side bodies are thus held immovably and reliably on the central body without additional parts simply by positive locking.
- the fault current module is connected “from above” in the embodiment according to FIG. 1, while this is done “from below” in the embodiment according to FIG. 3.
- the circuit breakers, not shown, are lined up on the outside 2.11 of the lower part. Their number depends on whether the fault current module is designed for two, three or four-pole construction.
