Description

Title of the invention: Electrical distribution system for an electric vehicle charging installation

[0001] The invention relates to an electrical distribution system for an electric vehicle charging installation.

[0002] An electric vehicle charging installation is typically installed in a parking lot. An electrical power cable that is connected to an electricity supply network runs along the parking spaces. Each parking space is equipped with a charging station connected to the electrical power cable by a branch conductor.

[0003] For safety reasons, the routing of the power supply cable must meet a certain number of standards and rules. The permitted solutions are as follows: the cable can be buried, placed high up out of reach of a person, or placed within reach of a person but in the latter case it must be protected, for example by being housed in a trunking.

[0004] However, in certain car parks, infrastructure constraints do not allow the following arrangements: - routing and fixing the cable to a wall (either by prohibition, or simply by the absence of a wall, for example in an outdoor car park such as a supermarket car park or on a roof terrace); - routing and fixing of the cable on a ceiling (for the reasons explained above); - a cable route in a buried gutter or even a trench covered with bitumen (if the owner of the premises is not the same as the owner of the charging installation, if the cost of the work is too high, for example, due to the configuration of the land, if it is in a green space protection zone, etc.). In addition, buried gutters, which may be equipped with ramps for the passage of vehicles, are not always sufficiently sized to allow all the cables to pass through; - a cable route on the ground (so as not to be an obstacle for pedestrians or disabled people to cross, to avoid damage to the cable and / or its protective covering by the passage of vehicles or green space maintenance tools, to avoid the accumulation of rainwater and waste, etc.).

[0005] In addition, an installer must set up the charging stations. For the reasons explained above, fixing stations to a wall may not be possible, whereas ground fixing can be excluded due to the significant sealing work that would be required to install a terminal, the ground footprint of which can be relatively substantial.

[0006] The present invention aims to propose a solution for routing cables and fixing charging terminals which can be implemented in constrained environments such as a parking lot without walls, ceilings or trench authorization.

[0007] For this purpose, the invention relates to an electrical distribution system for an electric vehicle charging installation, the system comprising:

[0008] - a conduit substantially closed except for its ends, intended to receive a power cable connected to an electricity supply network, the conduit extending along the installation in the mounted position;

[0009] - at least two conduit supports, each support comprising, in position rise:

[0010] — a foot located lower than the conduit, the foot comprising a portion for fixing to the ground ;

[0011] — a support portion linked to the foot and on which the conduit rests, the support portion being located above and at a distance from the ground fixing portion;

[0012] at least one of the supports further comprising at least one area for receiving a charging terminal.

[0013] Thus, with the system according to the invention, in the mounted position, the conduit receiving the electrical power supply cable from the terminals is located above the ground and at a distance from the ground. In addition, the foot provides mechanical support for the conduit and keeps it in position.

[0014] For the installation of the cables, there is therefore no need for a wall or a ceiling, nor is it necessary to dig a trench. The cables also do not run on the ground. Consequently, the system according to the invention can be installed in a very large number of environments, without requiring major works. The invention is particularly useful in the case of installation on an outdoor car park, in the case of collective housing or a tertiary building, when digging a trench is not viable.

[0015] Preferably, the conduit is fixed to each of the supports, for example at the level of the support surface.

[0016] According to one embodiment, the receiving area of ​​a charging terminal comprises a substantially flat face of the support which has sufficient dimensions, preferably at least equal, to those of the rear wall of the terminal, and which is configured to cooperate with said rear wall, in particular by contact.

[0017] For example, the rear wall of the terminal is screwed onto the receiving area. As a variant or in addition, it may be provided that the receiving area comprises members of hooking the terminal.

[0018] The receiving zone may extend orthogonally to the duct or parallel to the duct, for example by being laterally offset relative to the duct.

[0019] According to one embodiment, the receiving area of ​​a charging terminal could be provided on a post-type element secured to the support.

[0020] According to a possible embodiment, the feet of all the supports are identical. Each foot may have a connection portion of at least one additional part, for example in the form of a housing for receiving a base portion of said additional part. The additional part may be chosen from: at least one fixing upright of an appendage intended to be located in the upward extension of the foot, a member provided with a light source, a member provided with a socket, in particular a power socket or a USB type socket.

[0021] The system is thus modular, and can be adapted to the specificities of each installation. This is particularly advantageous given the variety of environments and charging stations, i.e. possible configurations. The invention makes it possible to reduce the number of references and the stocks required to manage all scenarios, thus considerably reducing costs while continuing to meet different needs.

[0022] The system may further comprise at least one and preferably several additional parts whose base portions have the same shape configured to cooperate with the housing provided on the foot of the support. For example, one or each base portion may be in the form of an arm having a section substantially identical to that of the housing, so that it can be engaged therein.

[0023] The appendix may be an information panel. Alternatively, the terminal reception area may be provided on the appendix.

[0024] According to a possible embodiment, at least one support has the general shape of a panel extending in a vertical plane, the panel having two opposite main faces. In the case where said support comprises at least one area for receiving a charging station, said receiving area can be provided on one of said main faces.

[0025] For example, the foot and the appendage, when present, each have the general shape of a panel, the two panels preferably being substantially coplanar.

[0026] The panel may be substantially parallelepipedal. It preferably has a thickness less than its height and its width. The panel may have a thickness less than a quarter of its width, for example of the order of 15 to 20% of the width.

[0027] The receiving area of ​​a charging station may be located above the conduit, or below the duct (i.e. on the foot). A reception area can be provided on each of the main faces of the panel.

[0028] According to a possible embodiment, the ground fixing portion comprises a plate fixed to the lower part of the foot and forming a collar at the periphery of the foot. If the foot is in the form of a panel, the transverse dimension of the collar may be less than the thickness of the panel. For example, the plate may have a surface area of ​​the order of 70% of the footprint of a charging station. This small footprint makes it possible to reduce the work of fixing to the ground.

[0029] According to a possible embodiment, at least one support comprises an appendage located in the extension of the foot upwards, and located higher than the conduit, the appendage preferably being a separate part added and fixed to the foot. In the case where said support comprises at least one area for receiving a charging terminal, said receiving area can be provided on the foot and / or on the appendage.

[0030] The fact that the appendix is ​​an added part makes it possible to give modularity to the system. The system can thus comprise supports having identical feet, to all or part of which an appendix can be added, as required. The appendix can have the general shape of a panel.

[0031] The appendage can be fixed to the foot by means of two lateral uprights, an opening being provided between the upper part of the foot, the lower part of the appendage, and the uprights. The conduit can pass through this opening. According to a possible arrangement, the support can have the general shape of a panel arranged orthogonally to the general direction of the conduit. In this case, it is possible to have on the same support a terminal on each of the opposite main faces of the support, that is to say for two adjacent parking spaces and preferably located on the same side of the conduit.

[0032] The foot may be offset from a vertical line running median to the conduit in a horizontal direction orthogonal to the conduit, the support portion comprising a console projecting from the foot in the direction of the conduit. According to another possible arrangement, the support may have the general shape of a panel arranged parallel to the general direction of the conduit. The console may be arranged substantially horizontally projecting orthogonally to the panel. In this case, it is possible to have on the same support a terminal on each of the opposite main faces of the support, that is to say for two parking spaces preferably located on either side of the conduit.

[0033] For at least one support, the support portion can be mounted on the foot in an adjustable manner according to a translation along the vertical direction and / or according to a ball joint, so as to allow the position of the conduit to be adjusted relative to the ground. This may involve an adjustment of horizontality and / or of inclination in the case of a non-level ground. perfectly flat. Alternatively, the support portion could be formed by at least part of the upper face of the foot and might not be adjustable.

[0034] For example, for at least one support, the support portion comprises a plate and a threaded rod which is mounted orthogonally under the plate and which extends substantially vertically while being engaged in a tapped hole provided in the foot.

[0035] It may be provided that at least one support further comprises a masking member configured to mask a conductor connecting the power cable housed in the conduit and the charging terminal mounted on the support, the masking member preferably being in the form of a rigid wall which is capable of being cut by an installer of said system and which is fixed to the foot or to a part mounted on the foot.

[0036] The electrical distribution system may further comprise a stop mounted on at least one support and projecting horizontally relative to the foot of said support, said stop being configured to prevent a vehicle from striking the support and / or the conduit.

[0037] According to a possible embodiment, the conduit comprises a plurality of tubular sections assembled together. In addition to modularity, this arrangement provides ease of storage and transport, and makes it possible to adapt to local configurations (elbows, slopes, etc.).

[0038] Furthermore, the conduit may comprise a base and a cover, the cover being configured to be able to be cut or pierced by an installer of said system to allow the passage of a conductor.

[0039] The system may further comprise at least one conduit extension sheath extending from one end of the conduit and intended to connect said conduit to an arrival zone of the power cable on or near the electric vehicle charging installation.

[0040] The system may further comprise at least one charging terminal mounted on a receiving area of ​​a support.

[0055] [Fig.l] represents an installation 100 for recharging electric vehicles. The installation 100 here comprises a parking lot including several parking spaces 101 as well as an electrical distribution system 1 according to the invention, comprising a recharging terminal 50 for each parking space 101 intended for an electric vehicle.

[0056] The installation 100 comprises a power cable 102 which is connected to an electricity supply network 103, for example via a meter 104 arranged at the edge of the installation 100. The electricity supply network 103 may here be in the form of a buried cable. The installation 100 further comprises, for each terminal 50, a branch conductor 105 (see [Fig.9]) which has one end connected to the power cable 102 and another end connected to the terminal 50.

[0057] The installation 100 may also comprise one or more communication cables (not shown) running with the power cable 102.

[0058] The electrical distribution system 1 is illustrated in [Fig.l] in the assembled position, i.e. with its various components fixed to the structure of the installation 100 and / or to each other, the system being ready for use.

[0059] The electrical distribution system 1 comprises a conduit 2 intended to receive the power cable 102 (as well as the communication cable(s), if applicable), to protect and conceal it, and thus guarantee the integrity of the power cable 102 and the safety of persons in the installation 100. The conduit 2 is substantially closed except for its ends. The terms “substantially closed” refer to the fact that, in practice, the conduit 2 is closed with the exception of orifices 3 ([Fig.9]) allowing the passage of the branch conductors 105 from inside the conduit 2 to each of the terminals 50.

[0060] In the mounted position, the conduit 2 extends along the installation 100, that is to say it runs along all of the parking spaces 101 equipped with a terminal 50, in order to enable each terminal 50 to be supplied. In the installation 100, the power cable 102 is preferably entirely housed inside the conduit 2, that is to say its free end, located after the last terminal 50 opposite the electricity supply network 103, is located in the conduit 2.

[0061] The conduit 2 is located high relative to the ground 106. For this purpose, the conduit 2 is mounted on and fixed to several supports 20. Preferably, in the installation 100, the supports 20 are the only elements of the electrical distribution system 1 which are fixed to the ground 106.

[0062] Furthermore, in order to protect and conceal the power cable 102 between its arrival zone 107 on or near the installation 100 and the conduit 2, the electrical distribution system 1 may comprise a sheath 6 extending the conduit 2, extending from one end of the conduit 2 to said arrival zone 107.

[0063] In the embodiment shown in [Fig.l], the arrival zone 107 is arranged at ground level 106, at the edge of the but outside the installation 100. The power cable 102 connected to the meter 104, in a buried manner, leaves the ground 106 in the arrival zone 107 to enter the sheath 6 before reaching the conduit 2. The work necessary for the electrical and mechanical connection of the installation 1 to the infrastructure and to the electricity supply network 103 is therefore carried out outside the installation 100, that is to say in a place where the creation of trenches may be possible and authorized. The sheath 6 is here in the form of an elbow of the same section as that of the conduit 2 of which the sheath 6 constitutes an extension up to the arrival zone 107. It should be noted that, at the other end of the conduit 2 (on the right in [Fig.l]), an angled sheath is also present but, in this configuration, it does not receive a power cable 102 and may only be present for aesthetic purposes.

[0064] According to other embodiments not illustrated, the arrival zone of the power cable 102 could not be located in the ground but at the level of a wall, a ceiling, a post or a box, for example.

[0065] Thus, whatever the embodiment among those mentioned above, the sheath 6 extending the conduit 2 rests on a structure and therefore does not require support, unlike the conduit 2.

[0066] As seen in [Fig.2], according to one embodiment, the conduit 2 comprises a base 4 and a cover 5 mounted on the base 4 to define a closed volume. The cover 5 can be cut or drilled by an installer of the system 1, to form the orifice(s) 3 for the passage of a conductor 105. The conduit 2 can have a rectangular section. It can be made of plastic or metal.

[0067] The conduit 2 may be in the form of a plurality of tubular sections 7 that an installer can more easily transport and handle, before assembling them together on the construction site.

[0068] Furthermore, also to facilitate installation, the cover 5 of the conduit 2 or one of its sections 7 can be removed from the base 4, so that the operator can make an orifice 3 there without risk to the power cable 102. Thus, depending on the needs and the evolution of these over time, typically when a new terminal 50 must be installed in the installation 100, the operator can easily carry out the operations necessary for connecting the new terminal 50. These operations include, in addition to making the orifice 3, making a seal 8 (illustrated schematically in [Fig.9]) between the orifice 3 and the branch conductor 105.

[0069] Each support 20 comprises a foot 21 which is fixed to the ground 106.

[0070] Preferably, the feet 21 of all the supports 20 of the electrical distribution system 1 are identical and can be completed by the addition of an additional part chosen from several possible parts, in order to obtain a modular and easily adaptable electrical distribution system 1.

[0071] The foot 21 comprises a ground fixing portion which may typically comprise or consist of a plate 22 fixed to the lower part of the foot 21. The plate 22 has reduced dimensions and for example a surface area of ​​the order of 70% of the ground area of ​​a charging station 50. As a result, the work of fixing the supports 20 to the ground does not require heavy work. The plate 22 can thus be fixed in the ground 106 by means of studs 23 or other fixing members (see in particular [Fig. 10]).

[0072] The foot 21 may be in the form of a panel, for example substantially rectangular. The foot 21 has a mean plane P21 which may typically extend in a vertical plane, the plate 22 being substantially orthogonal to the panel, therefore horizontal in the mounted position. As can be seen in Figures 3 and 7, in particular, the foot 21 may comprise a frame 24 on which two plates 25 are mounted (one of them not being shown in [Fig. 3] to allow the interior of the foot 21 to be seen). The panel forming the foot 21 has two opposite main faces 26, parallel to the plane P21, which are the outer faces of the plates 25.

[0073] The foot 21 may also comprise two lateral housings 27 extending vertically which are for example made of square section profiles. Each housing 27 forms a connection portion of at least one additional part to the foot 21, since it can receive a base portion of such an additional part. Advantageously, all the additional parts intended to be connected to the foot 21 have a base portion having the same shape complementary to that of the housing 27, here an elongated shape of square section capable of being inserted into the housing.

[0074] Furthermore, the foot 21 has an upper face 28, the housings 27 opening into said upper face. The upper face 28 may form a support portion on which the conduit 2 rests; it may be provided with holes 29 for the passage of members for fixing the conduit 2, more particularly the base 4 of the conduit 2.

[0075] According to a possible embodiment illustrated in [Fig. 3], the support portion comprises a plate 30 and a threaded rod 31 which is mounted orthogonally under the plate 30. The threaded rod 31 is engaged in a tapped hole 32 provided in the foot 21, more particularly in the upper face 28 of the foot 21, and extends substantially vertically between the plates 25, thus being largely invisible. The plate 30 may be provided with holes 33 for the passage of members for fixing the conduit 2. Thus, the plate 30 is mounted on the foot 21 in an adjustable manner according to a translation along the vertical direction, that is to say it may be more or less spaced from the upper face 28. This allows the height position of the conduit 2 to be adjusted relative to the ground 106.More specifically, an adjustment of the position of each section 7 is thus possible, so as to give horizontality to the conduit 2 as a whole, despite possible irregularities in the ground 106.

[0076] In a variant not shown, the plate 30 could be mounted on the foot in an adjustable manner using a ball joint, so as to allow the inclination of the conduit 2 to be adjusted relative to the ground 106.

[0077] The foot 21 is thus located lower than the conduit 2, either under the conduit 2, or offset from the conduit 2 as will be seen later.

[0078] In practice, for the installation of the electrical distribution system 1, the installer fixes feet 21 to the ground 106, spaced apart from each other, for example substantially regularly. The feet 21 may be substantially aligned, as illustrated in [Fig.l], or not, depending on the arrangement of the parking spaces 101.

[0079] When the ground 106 is loose, fixing the plate 22 by studs 23 is not possible. In this case, one or more bases 34 can be used. The base 34 comprises at least one relatively long rod 35 secured to a plate 36, the rod 35 being able to be driven quite deeply into the ground 106 so that the plate 36 is substantially flush with the surface of the ground 106. The rod 35 can be sealed in the ground 106. The plate 22 of the support 20 is then fixed to the plate 36. In the example of [Fig. 4], two separate bases 34 are provided, each comprising a plate 36 and a rod 35 with a cross section and tapering towards a point lower. In the example of [Fig.5], a single base 34 is provided comprising a plate 36 from which four substantially cylindrical rods 35 protrude.

[0080] Then, the different sections 7 of the conduit 2 are assembled together and fixed to the corresponding foot(s) 21. If necessary, the position of each section 7 relative to the ground 106 is adjusted. The conduit 2 is preferably generally at a constant distance from the ground, for example substantially horizontal if the ground 106 is horizontal. The distance between the conduit 2 and the ground 106 - that is to say the distance between the ground fixing portion and the support portion of the support 20, i.e. substantially the height of the foot 21 according to one embodiment - may be at least 50 cm, or even at least 1 m.

[0081] The structure of each support 20 can be adapted according to the initial needs and the evolution of the needs.

[0082] A certain number of supports 20 may comprise only one foot 21 and have only a function of supporting the conduit 2.

[0083] While keeping this basic structure, it is possible to provide, as illustrated in [Fig. 6], that a support 20a comprises at least one member 37 provided with a light source 38, a socket, in particular a power socket or a USB type socket, or offering another functionality to the users of the electrical distribution system 1. The member 37 can take the form of an arm inserted into the housing 27, and having for this purpose a section substantially identical to that of the housing 27. The support 20a can thus have a U-shaped upper part in which the conduit 2 is arranged, orthogonally to the plane P21, as can also be seen in [Fig. 1].

[0084] Furthermore, as illustrated in [Fig.7], a support 20b may further comprise two lateral uprights 39 each inserted in a housing 27 and carrying an appendage 40, which is preferably located in the extension of the foot 21 upwards.

[0085] The appendage 40 may be in the form of a panel, for example substantially rectangular. The appendage 40 has a mean plane P40 which may typically extend in a vertical plane. According to a possible embodiment, the mean plane P21 of the foot and the mean plane P40 of the appendage 40 are substantially parallel or coincident. The appendage 40 may comprise two plates 41 fixed to the lateral uprights 39. The panel forming the appendage 40 has two opposite main faces 42, parallel to the plane P40, which are the outer faces of the plates 4L

[0086] The appendage 40 is therefore located higher than the conduit 2. In addition, an opening 43 is provided between the upper face 28 of the foot 21, the lower part of the appendage 40, and the lateral uprights 39.

[0087] Such an appendage 40 of a support 20b can serve as an information panel.

[0088] Among the supports 20, some initially carry a charging terminal 50, and the other supports 20 can subsequently be equipped with such a terminal 50, depending on the evolution of needs, in particular when the user of a parking space 101 equips himself with an electric vehicle.

[0089] Thus, all or part of the supports 20 of the electrical distribution system 1 comprises at least one receiving zone 45 for a charging terminal 50. The receiving zone 45 can be provided on the foot 21 and / or on the appendage 40 of a support 20. The receiving zone 45 can be provided on one of the main faces 26 of the foot 21 and / or 42 of the appendage 40.

[0090] As illustrated schematically in [Fig.8], a terminal 50 comprises a box 51 and is provided with a socket 52 to which a vehicle charging cable can be connected. For this purpose, the box 51 comprises one or more orifices 53 for the passage of electrical or communication conductors. The terminal 50 may also comprise a door 54 provided to close the opening of the box 51.

[0091] Each terminal 50 may also include an electronic system for managing access to the terminal and / or managing consumption, housed in the box 51.

[0092] The box 51 may further contain an electrical panel 55 illustrated schematically in [Fig.8]. The electrical panel 55 may comprise various electrical devices including: a fuse switch, a meter, a circuit breaker. These devices are connected in series between the branch conductor 105 and the socket 52, preferably in the order in which they are listed.

[0093] The terminal 50 is fixed on the support 20 concerned, in the receiving zone or zones 45 provided on the support 20. In particular, a terminal 50 can be fixed on one or each of the opposite main faces 42 of the appendage 40 of the support 20.

[0094] To connect a terminal 50 to the power cable 102 running in the conduit 2, the installer removes the cover 5 from the relevant section 7 of the conduit 2. He connects one end of a branch conductor 105 to the power cable 102, makes an orifice 3 in the cover 5 of the conduit 2 and passes the branch conductor 105 through it so that it can exit the conduit 2, then replaces the cover 5 and makes the appropriate seal 8.

[0095] It should be noted that access to the power cable 102 is preferably restricted. Thus, various means may be provided to prevent the cover 5 from being removed by any person. For example, access to the interior of the conduit 2 may require the use of tools that are not readily available to the general public (such as a screwdriver with a specially shaped imprint, such as a Torx screwdriver), or even proprietary tools of the electricity supply network manager 103. A locking device may also be provided (seal, lead, or even lockout, etc.).

[0096] The bypass conductor 105 is then passed through the orifice 53 of the box 51 then connected to socket 52, generally via electrical panel 55.

[0097] According to a possible arrangement, the support 20 provided with an appendage 40 is placed orthogonally to the general direction of the conduit 2, the conduit 2 passing through the opening 43 of the support 20. As is the case with the leftmost support 20 in [Fig.l], with such an arrangement, a support 20 arranged for example between two adjacent parking spaces 101 located on the same side of the conduit 2 can carry a terminal 50 for each of these parking spaces 101.

[0098] According to another possible arrangement, the support 20 provided with an appendage 40 is placed parallel to the general direction of the conduit 2. In addition, the foot 21 is not located vertically under the conduit 2, but offset laterally relative to the conduit 2. In this case, the support 20 may comprise a console 44 projecting from the foot 21 in the direction of the conduit 2, the console 44 serving as a support portion for the conduit 2 or being linked to a part serving as a support portion. The console 44 may be fixedly mounted on the foot 21. In order to adjust the height of the conduit 2 relative to the ground 106, there may be different possible mounting heights of the console 44 on the foot 21 and / or a part similar to the plate 30 movable vertically relative to the console 44.

[0099] This may be implemented due to a lack of available space around the conduit 2, in particular due to the presence of a nearby wall, as illustrated in [Fig.9].

[0100] This is not, however, the only application of this type of arrangement. Thus, as is the case with the rightmost support 20 in [Fig.l], with such an arrangement, a support 20 arranged for example at a parking space 101 can carry a terminal 50 for this space as well as the parking space 101 which is adjacent to it, on the other side of the conduit 2 (the console 44 is not visible in [Fig.l]).

[0101] According to a possible embodiment, as illustrated in [Fig. 10], a support 20 may comprise a masking member 46 for the branch conductor 105. This masking member 46 may be in the form of a rigid wall fixed to the foot 21 or to the lateral uprights 39 and arranged opposite the opening 43. In order to allow the passage of the conduit 2 in the opening 43, the installer may cut said wall along a cutting line 47. This wall may form a generally trapezoidal housing, widening away from the conduit 2.

[0102] In the above, the case of one or more terminals 50 mounted on the appendage 40 of the support 20, i.e. above the conduit 2, has been described. However, this should not be considered as limiting. Thus, as illustrated in [Fig. 1 1], it is entirely possible to fix the terminal(s) 50 on the foot 21 of the support 20, i.e. below the conduit 2.

[0103] As illustrated in [Fig.12], the electrical distribution system 1 may further comprise a stop 60 mounted on a support 20, projecting horizontally relative to the foot 21 of the support 20, in the direction of a parking space 101. This stop 60, which may for example be in the form of one or more hoops made of metal tubes, is configured to prevent a vehicle from hitting the support 20 and / or the conduit 2.

[0104] Furthermore, at the junction between two sections 7 of the conduit 2, a connecting piece 61 can be placed, as illustrated in [Fig. 13]. The connecting piece 61 ensures continuity between the sections to guarantee sealing and thus better protect the power cable 102. It also prevents a person from getting a finger trapped between two sections 7. Furthermore, by providing that the connecting piece 61 forms a projection on the cover 5, an obstacle is created which discourages the use of the conduit 2 as a skateboard track or the like.

[0105] The invention provides significant advantages including:

[0106] - ease of implementation, in particular due to a minimization of work required installation (above-ground conduit and low-footprint supports fixed using minimally invasive techniques);

[0107] - adaptability to needs and scalability (in particular easy subsequent addition of points dump) ;

[0108] - mechanical robustness, involving little maintenance and great durability;

[0109] - compactness and modularity, in terms of storage, transport, handling, and up to installation on site;

[0110] - compatibility with existing systems.

[0111] It goes without saying that the invention is not limited to the embodiments described above as examples but that it includes all technical equivalents and variants of the means described as well as their combinations.
