ASSEMBLY INCLUDING A CONTROL PANEL

TECHNICAL AREA

The present invention relates to an assembly comprising a control panel, an individual main circuit breaker, an electric meter and an electric circuit breaker.

STATE OF THE PRIOR ART

A state-of-the-art control panel has a front face to which an individual main circuit breaker, an electric meter and an electric circuit breaker are conventionally attached.

The control panel is conventionally made up of a front half-shell which carries the front face and a rear half-shell which are fixed to each other and which define between them an interior volume in which electrical conductors are arranged.

When a technician has to install such a control panel, he starts by fixing the rear half-shell to a wall, he installs the various materials on the front side on the front half-shell, then the conductors are put in place. 'aft of the front demicoque by connecting them to the various equipment, then the assembly is fixed to the rear half-shell to close it.

During installation, the technician also connects the conductors of the electrical distribution network and the conductors that will electrically supply the building concerned.

Although such an installation is simple and quick, it leaves it possible for malicious persons to hack the installation by connecting bypass conductors upstream of the electric meter, which can be detrimental from a security point of view, but also from a commercial point of view. In addition, generally the conductors of the electrical distribution network are in sheaths and are not accessible once the control panel is fixed, but it can happen that the sheath is not present and the conductors of the electrical distribution network are then accessible for possible fraud. So we have to find a new way to protect the control panel from fraud.

DETAILED DESCRIPTION OF EMBODIMENTS

In the following description, the terms relating to a position are taken with reference to a control panel in the normal position of use, that is to say when it is fixed to a wall and as shown in the Fig. 1.

Fig. 1 shows an assembly 100 which comprises a control panel 102 which has a front face 104 to which are attached an individual main circuit breaker 106, an electric meter 108 and an electric circuit breaker 110.

The control panel 102 also has a rear face which comes against a wall during installation.

The assembly 100 is connected between supply conductors 112 of an electrical distribution network and downstream conductors 114 which electrically supply a building and which are connected by means of a connection strip 130, for example of the type domino, which is accessible from outside the control panel 102.

The control panel 102 consists of a front half-shell 116a which carries the front face 104 and a rear half-shell 116b which carries the rear face (310, Fig. 3). The front half-shell 116a and the rear half-shell 116b are fixed to each other here by screws 118 distributed here at each corner.

The two half-shells 116a-b define between them an interior volume in which electrical connection conductors 120a-c are arranged. The two half-shells 116a-b have side walls which delimit the interior volume and prevent access to the interior of this interior volume from the exterior outside the orifices provided for this purpose for passing the conductors and described below. after. The side walls extend all around the interior volume and therefore of the control panel 102.

The individual main circuit breaker 106 has upstream connection terminals to which the supply conductors 112. The introduction of the supply conductors 112 into the control panel 102 is effected by introduction holes provided in this connection. effect in the upper part and explained below.

First electrical connection conductors 120a are connected between downstream connection terminals of the individual main circuit breaker 106 and upstream connection terminals of the electric meter 108. To this end, the control panel 102, and more particularly the half-shell front 116a has windows on the front face 104 through which the ends of the first electrical connection conductors 120a pass to connect to the appropriate connection terminals.

Second electrical connection conductors 120b are connected between downstream connection terminals of the electric meter 108 and upstream connection terminals of the electric circuit breaker 110. To this end, the control panel 102, and more particularly the front half-shell 116a has on the front face 104 of the windows through which the ends of the second electrical connection conductors 120b pass to connect to the appropriate connection terminals.

Third electrical connection conductors 120c are connected by first ends to the downstream connection terminals of the electric circuit breaker 110 and by second ends to the upstream connection terminals of the connection strip 130. At this fm, the control panel 102, and more particularly the front half-shell 116a has windows on the front face 104 through which the ends of the third electrical connection conductors 120c pass to connect to the appropriate connection terminals. The second ends of the third electrical connection conductors 120c which connect to the upstream connection terminals of the connection strip 130 exit towards the rear of the control panel 102 by outlet openings provided for this purpose in the lower part of the control panel. control 102, and more particularly the front half-shell 116a on the front face 104.

The connection strip 130 has downstream connection terminals to which the downstream conductors 114 are connected.

To make the connections of the electrical connection conductors 120a-c to the individual main circuit breaker 106, to the electric meter 108 and to the electric circuit breaker 110, each of these devices 106, 108, 110 has a removable cover which is removed to allow the access to the desired connection terminals. After connection, these covers are replaced and fixed for example by screws.

The covers of the electric meter 108 and the electric circuit breaker 110 are then locked, for example using a security seal (plastic seals, lead, etc.) which attests to the fact that no one has removed these covers after the installation of electrical connection conductors 120a-c.

When the individual main circuit breaker 106, the electric meter 108 and the electric circuit breaker 110 are in position and sealed, the accesses to the windows of the front face 104 are closed off because these devices and their covers cover the windows.

Fig. 2 shows an enlargement of detail II of FIG. 1.

After the front half-shell 116a and the rear half-shell 116b have been fixed to each other, a security system 200 is put in place between the front half-shell 116a and the rear half-shell 116b in order to to warn of any opening of the control panel 102. The security system 200 is such that an opening of the control panel 102 can only be done by destruction of said security system 200. The security system 200 is for example a seal plastic, lead or clip. The security system 200 is destroyed when the front half-shell 116a and the rear half-shell 116b are separated from each other.

In the case of a seal, the rear half-shell 116b has a loop 202 and the front half-shell 116a has a seal orifice 204. After covering the rear half-shell 116b by the front half-shell 116a, the loop 202 passes through the seal hole 204 and the security seal 200 can be placed in the loop 202.

In the embodiment of the invention presented here, a security system 200 is implemented at each corner.

Fig. 3 shows a rear view which shows the inlet ports 302 and the outlet ports 304.

The introduction orifices 302 are produced in the front face 104 and at the rear of these introduction orifices 302, the control panel 102 has a recess 306 which is delimited in the upper part by a side wall of the half-shell aft 116b, on the sides and in the lower part by first connecting walls of the front half-hull 116a and second connecting walls of the rear half-shell 116b. The introduction orifices 302 are arranged opposite the upstream connection terminals of the individual main circuit breaker 106 to allow the introduction of the supply conductors 112 to the upstream connection terminals. The front face 104 thus has, for each upstream connection terminal of the individual main circuit breaker 106, an introduction orifice 302 disposed opposite said upstream connection terminal.

The connecting walls extend perpendicular to the front face 104.

The first connection walls extend from the front face 104 towards the rear demo-hull 116b, and the second connection walls extend from the rear face 310 towards the front half-shell 116a. The first and second connecting walls come into contact with each other by their free ends and are thus contiguous.

Thus, the recess 306 is open only on the rear face which comes against the wall after installation and on the front face 104 by the insertion orifices 302. Perpendicular to the front face 104, the recess 306 is only delimited by the front 104.

There is therefore no opening between the recess 306 and the interior volume, and the passage between the recess 306 and the interior volume is therefore impossible and the risks of fraud are avoided.

The dimensions of the recess 306 are determined to facilitate the positioning of the supply conductors 112 in the introduction orifices 302 which are preferably dimensioned to allow the passage of a single conductor.

To allow the passage of the supply conductors 112 through the side wall of the rear half-shell 116b, said side wall has notches 308 which are preferably dimensioned to allow the passage of a single conductor.

The installation of the electrical connection conductors 120a-c, their connections to the individual main circuit breaker 106, to the electric meter 108 and to the electric circuit breaker 110, the installation of seals on the electric meter 108 and the electric circuit breaker 110, as well as closing the control panel 102 and installing security systems 200 on the control panel are carried out in the factory and no longer in the field, which limits the risk of fraud.

When the assembly 100 thus equipped arrives at the place of installation, the technician only has to introduce from the rear the supply conductors 112 into the insertion orifices 302, to connect them to the terminals of upstream connection of the individual main circuit breaker 106, attach the control panel 102 to the wall and seal the cover of the individual main circuit breaker 106 for example with a lead which attests to the fact that no one has removed this cover after installation.

The technician also connects the third electrical connection conductors 120c to the upstream connection terminals of the connection strip 130 and the downstream conductors 114 to the downstream connection terminals of the connection strip 130.

The rear half-shell 116b has holes 122, here four in number and distributed in the corners, which allow the installation of fixing screws which are screwed into a wall of the building. These holes 122 are accessible from outside the control panel 102 and it is not necessary to open the control panel 102. The fixing screws can be fitted with screw covers which can be sealed, thus making it possible to lock the disassembly of the assembly 100 and thus making fraud visible from the outside.

Fig. 4 shows a variant of the invention.

To further secure the installation, before installing the control panel 102 on the wall, the recess 306 is closed on the rear face 310 by a removable hatch 402 which closes the opening of the recess 306 at the rear face 310.

The hatch 402 is held by any suitable system such as screws or clips.

Thus, access to the introduction ports 302 is even more difficult.
