Description

[0001] The invention relates to a meter station with a receiving device for additional meter devices according to claim 1 and to a meter cabinet with a meter station for receiving at least one electronic meter, in particular a household meter, according to claim 11.

[0002] Electric meters for recording the amount of electricity consumed, i.e., the total amount of electrical energy supplied to a number of consumers, are housed in meter cabinets. The metering station located in the meter cabinets consists of a meter panel and a lower and an upper connection compartment – ​​in accordance with DIN 43870. Additional metering devices, such as relays, switches, control devices, fuses, and feed-in devices, are connected upstream of the meters. These devices are often mounted on DIN rails in the lower or upper connection compartment of the meter panel and are subject to the regulations of the electrical utility company (EVU).

[0003] The elements arranged one above the other - meter panel with the associated lower connection compartment below and the associated upper connection compartment above - form a structural unit and are described, for example, in DE 195 42 066 A1.

[0004] DE 10 2004 022 784 A1 describes a meter panel assembly that can be installed in a meter cabinet. It comprises a support housing with space for at least one electric meter and additional devices such as tariff and control devices. The assembly consists of several housing sections that allow for a clear separation of functions. A vertically mounted meter outlet housing section can be integrated above the meter panel. The design allows for easy installation on support rails in the meter cabinet. Overall, the invention described in the publication aims to provide a compact and functional solution for organizing the meter cabinet space.

[0005] Patent DE 10 2009 029 931 B4 describes an electrical distribution board for domestic installations that includes a metering station with an electricity meter. The design includes a support device attached to the inner surfaces of the vertically extending side walls of a housing for holding electrical switching and control devices. The main line branch terminal is integrated into the housing, and connecting lines are provided between the connection terminals of the electricity meter and the main line branch terminal. The installation of the support device is facilitated by the arrangement of strips running parallel to the floor wall. The patent aims to optimize the installation and handling of electrical switching devices in domestic installations.

[0006] The three areas of the meter locations provided for in DIN 43870 with the meter field and the lower and upper connection compartments form the meter location with the vertical support rails.

[0007] The spaces above and below the meter panel are usually equipped with top-hat rails or copper busbars, which serve to accommodate additional installation devices in accordance with the DIN 43880 standard. The spaces above and below the meter panel are only covered at the front, and the rear wall of the cabinet is freely accessible, i.e., constructed without additional walls. When installing multiple meter panels or distribution panels in one cabinet, the meter panels or distribution panels may be separated from each other by vertical partition walls. Within a meter panel, spaces are usually divided by horizontal partition walls. However, this does not achieve a completely separate area within the meter panel.

[0008] The invention is based on the object of creating a metering station with a metering field for accommodating at least one electronic meter, in the upper and / or lower connection space of which a receiving device for additional metering devices is arranged, which can be mounted in a simple and cost-effective manner in existing as well as new metering stations above and below the metering field and the receiving device forms an area within the metering station that is separated or closed off on all sides.

[0009] This object is achieved according to the invention by a metering station with a receiving device for additional metering devices according to patent claim 1 and a metering cabinet with a metering station for receiving at least one electronic meter according to claim 11.

[0010] Advantageous embodiments and expedient developments of the invention are specified in the subclaims.

[0011] The invention relates to a meter station, with a meter field for receiving at least one electronic meter, an upper and a lower connection space for receiving additional meter devices, with at least two vertically extending support rails, wherein the support rails are connected to one another at least via a meter support plate receiving the meter.

[0012] According to the invention, fastening elements are provided in the upper and / or lower connection compartment on the support rails, onto which at least one mounting device for the additional meter devices can be pushed or plugged. The mounting device, formed as a one-piece plastic part, consists of a base part, a front side running parallel thereto, a rear wall, and two opposite side walls. The side walls run vertically in the assembled state, i.e., when the mounting device is attached to the meter location.

[0013] Advantageously, the receiving device is a plastic molded part which is easy to manufacture and which has milled grooves in its base part and its front side for receiving a slide element and, in the installed state, is provided on its rear wall with break-out recesses which are intended in particular as inlet openings for cable feedthroughs.

[0014] When installed, the base part and / or the front end each have a forward-opening, particularly rectangular, closable recess or opening. These recesses or openings can be closed with the insertable lower or upper part, respectively, designed as a slider element, which forms a horizontal partition to another receiving device or a closing or partition wall to the upper or lower connection compartment. Like the receiving device, the slider element is made of a simple and cost-effective plastic part.

[0015] To accommodate the respective slide element, the base part and / or the front side are equipped with internal, continuous, elongated recesses, such as guide grooves or guide slots.

[0016] In one embodiment of the invention, mounting elements are provided on the front side of the side walls of the receiving device, to which at least one support device, in particular a top-hat rail, can be attached, on which the additional meter devices can be mounted. The mounting elements are designed in such a way that they also enable secure attachment of the receiving device to the fastening elements.

[0017] According to a further embodiment, the lower and / or upper part is provided with further breakable cutouts or recesses, in particular circular recesses, for cable passage.

[0018] In an advantageous further development, at least one of the opposite side walls of the receiving device, which in the installed state run vertically, has elongated rectangular and breakable recesses for cable passage.

[0019] The meter cabinet according to the invention, with a meter panel for accommodating at least one electronic meter, in particular a household meter, is characterized in that fastening elements, so-called spacers, are attached to vertically extending support rails below and above the meter panel, i.e. in the upper and lower connection space of the meter cabinet, onto which at least one receiving device for additional meter devices can be pushed or plugged.

[0020] The plastic mounting device can be attached to the spacers with fasteners, preferably screws. These fasteners can also be used to protect a top-hat rail mounted in the mounting device for accommodating the additional meter devices from external influences and / or to attach a cover to protect the additional meter devices. The cover, which is applied to the still open front of the mounting device and is preferably hood-shaped, enables the mounting device to form a separate or enclosed area within the meter panel.

[0021] It has proven particularly advantageous that the mounting device is designed in such a way that it can be arranged in a height grid according to the DIN 43870 standard with further mounting devices arranged above or below it, and thus the available space, i.e. the installation height for the additional meter devices, can be easily extended from, for example, 150 mm to 300 mm or even to 450 mm when the lower or upper parts are not inserted.

[0022] If the width of the available space in the upper or lower connection compartment is already set at 250 mm according to the DIN 43870 standard, the connected compartment can be easily opened by removing the inserted sliding elements that act as partitions and are inserted into the respective front side of the mounting device, and can thus be used as a continuous area for corresponding additional meter devices with larger dimensions.

[0023] By means of additional partition walls, in particular horizontal partition walls, which are inserted or pushed into the respective front side and / or into the respective base part of the mounting device as sliding or insert parts, the available space for the additional meter devices can be further varied and / or individually adapted and divided.

[0024] The invention, further embodiments and advantages will be described in more detail with reference to the exemplary embodiments shown in the following drawings.

[0025] They show: Fig. 1 a section of a meter panel with a meter field and an upper connection compartment according to the state of the art, Fig. 2 shows a section of an exemplary embodiment of the metering station according to the invention before and after the installation of a mounting device for additional metering devices, Fig. 3 shows a section of another exemplary embodiment of the metering station according to the invention before and after the installation of several receiving devices, Fig. 4 a section of the further exemplary embodiment of the metering station according to the invention before and after the installation of two mounting devices arranged one below the other, which are equipped with top-hat rails, Fig. 5 an exemplary meter panel according to the invention with meter field and upper and lower connection space, Fig. 6 the metering station according to the invention with meter field and the lower and upper connection compartment, wherein the receiving device located in the upper connection compartment is closed with a common cover, Fig. 7 an exemplary embodiment of the receiving device according to the invention in front and rear view, Fig. 8 an exemplary slide element with front and back, and Fig. 9 an exemplary front cover for the receiving device.

[0026] Fig. Figure 1 shows a section of a meter panel 1 with a meter field 11 and an upper connection compartment 13 of a domestic electrical installation according to the prior art. The lower connection compartment located below the meter field 11 is not shown, but reference numeral 14 indicates its location below the meter field 11.

[0027] The meter panel 11 is located between two vertically and parallel arranged support rails 10. In the meter panel 11, a meter support plate 12 for receiving a meter, in particular a household meter, is attached to the support rails.

[0028] Below and above the meter panel 11 are the upper and lower connection compartments 13 and 14, equipped with top-hat rails 15, for additional meter devices such as relays, switches, control devices, and fuse and feed-in devices. Spacers 16 are provided above and below the top-hat rails 15 and are attached to the mounting rails 10.

[0029] In the upper connection compartment 13, partition walls 2 and 3 are provided between the top-hat rails 15 in the horizontal and vertical directions to separate individual compartments from each other. Since the meter compartment 1 shown here can be used in various cabinet types, the space behind the top-hat rails 15 is designed as an open area 4.

[0030] In the Fig. 2 shows a section of an exemplary embodiment of the meter panel 1 according to the invention before and after the installation of a receiving device 20 for additional meter devices above the meter panel 11 in the upper connection space 13.

[0031] The plastic mounting device 20 shown here, also referred to below as the insert, is plugged or slid onto the spacers 16 mounted on the support rails 10. In the example shown, two spacers 16 are provided on each of the two support rails 10, which are guided through corresponding openings provided, in particular, on the rear wall of the insert 20 when installed.

[0032] The insert 20 is formed from a base part 23, a front side 24 running parallel thereto, a rear wall 22 and two opposite side walls 25, wherein the side walls 25 run vertically in the assembled state, i.e. when the receiving device 20 is fastened to the meter location 1.

[0033] Fig. 3 shows a section of a further exemplary embodiment of the meter station 1 according to the invention before and after the installation of several inserts 20 above the meter field 11 in the upper connection space 13.

[0034] In order to increase the space for additional metering devices, a second slot 20 is provided above the one shown in the Fig. 2 shown plugged-in module 20 onto further spacers 16 arranged on the support rails 10. Although not shown, additional modules 20 can also be plugged or pushed onto further provided spacers 16 in both the upper and lower connection compartments 13, 14 of meter location 1 via the further plug-in module 20.

[0035] Because the base parts 23 and / or the end face 24 of the illustrated inserts 20 each have a front-open, particularly rectangular, recess or opening 212 when installed, the height grid specified by DIN 43870 for the installation of the additional meter devices can be expanded, for example, from 150 mm to 300 mm or even to 450 mm. The resulting connected installation space can also be used as a continuous surface for larger devices or equipment, or equipment with increased space requirements.

[0036] The Fig. Figure 4 shows a section of the further exemplary embodiment of the metering station 1 according to the invention before and after the installation of two stacked inserts 20 on spacers 16 fastened to the support rails 10. The inserts 20 shown here are equipped with support devices 15, in particular with DIN top-hat rails for additional metering devices according to DIN 43880, and are arranged in the upper connection compartment 13 of the metering station 1. The top-hat rails 15 are fastened to the inner surfaces of the side walls 25 and serve as support devices 15 for the additional metering devices.

[0037] The recesses 212 in the base part 23 and / or in the front side 24, which are open to the front, can be closed with lower or upper parts designed as sliding elements 21. For this purpose, the sliding elements 21 are inserted into internal, continuous, elongated recesses located on the base parts 23 and / or front sides 24, such as guide grooves or guide channels, which are in the Fig. 7. This advantageously creates an area within the metering station 1 which only needs to be closed at the front and which is closed off by a cover 30 which can be applied from the front, as shown in Fig. 6, is covered in such a way that the inserts 20 form an area within the meter location 1 that is separated or closed on all sides.

[0038] The drawer units 20 are fastened to the vertical support rails 10 by means of connecting means 33, preferably designed as screws, which can simultaneously serve to fasten the top-hat rails 15 in the drawer unit 20. The drawer units 20 are held together in a form-fitting manner by plug-on or attached connectors 32.
