Description

Module for measuring and displaying energy quantities and / or powers transmitted in a line secured by a circuit breaker

The invention relates to a module for measuring and displaying quantities of energy and / or services, which are transmitted by at least one secured with a circuit breaker line, wherein the module comprises a support member and a display element, the Trägereiement kraftschiüssig with the circuit protection schaiter is connected, wherein the Module at least one current sensor for measuring an electric current of the at least one line and a

Data processing device to process the measured electric current for displaying amounts of energy and / or services has.

In order to protect electrical lines of a home system against overload and short circuit, usually used in an electrical distribution or fuse or meter box of the house system line protection shunt, which break in the fold of overload or short circuit, an electric current flow in one or more line circuits. For additional determination and representation of a power consumption of a line circuit are known from the prior art module, which can be arranged at or in the vicinity of a circuit breaker to an electric current or an electric power, which in a through the

Protective conductor is transmitted to line protection, to measure and represent by means of a display element. The energy consumption is usually taken from the determined current and one or against a neutral conductor

calculated electrical voltage.

A representation of energy consumption of several circuits of Hausaniage or a comparison of these with each other requires attaching modules to each line or their Leitungsschutzschaitem. However, this is associated with a high cost. Alternatively, it is also conceivable to attach a single module in succession to different circuit breakers, in order to successively reduce the respective energy consumption of the various modules

To determine management circuits. However, this approach is cumbersome and time-consuming and therefore not particularly suitable for a non-specialist. It would be desirable, the energy consumption of individual circuits of a Hausanlage both individually but also in comparison to each other to represent, in particular in a way that can be operated by a non-specialist without difficulty. This is where the invention starts. The object of the invention is to provide a module of the type mentioned, which allows a simple, inexpensive and flexible representation of energy consumption of hedged by circuit breaker lines. The object is achieved by a module of the type mentioned, in which the display element and the support member by an electric

Plug connection are releasably connected together to receive data signals from

Carrier element to the display element to transmit, and / or the module

has arranged on opposite sides of the module arranged electrical data contacts for data transmission, so that data can be transmitted between a plurality of directly juxtaposed modules.

The basis of the invention is the idea to achieve high flexibility by modularizing the module, so that in this way a cost-effective design is achieved, which can also be operated in a simple and intuitive way. On the one hand, a user should be able to read the energy or power consumed by a line circuit directly to the circuit breaker of a fuse box, on the other hand, a user-friendly display element with a display is a costly component and it would be inappropriate accordingly to each circuit breaker such to arrange. As a solution to this problem is inventively proposed to design a module such that this is a flexible use of

Display elements for displaying detected electrical data allows. For this purpose, on the one hand, it is provided that the display element and the carrier element are releasably connected to each other by an electrical plug connection. This makes it possible, for example, that cost-effective carrier elements are arranged on a plurality of circuit breakers and one or more display elements can be flexibly changed between different carrier elements. On the other hand, it is advantageously additionally or alternatively provided that the module has electrical data contacts arranged on opposite sets of the module for data transmission, so that approximately one Arrangement of modules immediately adjacent to each other in a fuse box leads to the fact that the electrical data contacts of the directly adjacent modules are connected to each other and data can be transmitted between the modules.

This opens up flexibility in many ways, depending on the application situation. A user can change a display element independently without great effort between circuit breakers connected to carrier elements and also or alternatively data can be exchanged between immediately juxtaposed modules, whereby a display element for displaying data concerning multiple circuits is used. Depending on the specific presentation desires of a user, different display and display modes may be used

Representation variants are combined. Thus, display elements with different functionality and correspondingly with different costs can be flexibly combined and replaced. For example, a display element may include a mechanical display, numeric display, LED display, or graphical display to represent energy usage. In addition to visual displays, acoustic displays are also conceivable in order to signal, for example, the exceeding of a limit value. With a simple and flexible attachable to the support member display element different display elements can be infected to a support element in a simple and secure manner. In particular, more complex display elements, such as display elements with displays, which are often also associated with maintenance, such as performing software updates, Can thus also be removed by a non-expert in a simple way from the circuit breaker and also attached again.

It is also advantageous if the at least one current sensor is arranged on the carrier element. As a result, a measured data acquisition is modularly separated from the display element. The display element can thus be easily and without having to take account of about measuring cable or a contact, be solved by the support member in particular, a loosening or changing the display element can be particularly easily performed, since a current measurement is decoupled from the display element. A current measurement is implemented in a simple and low-error manner, that the current sensor is designed as a current transformer. An inductive measurement of the current strength makes the current measurement particularly robust and resistant. The measurement of the current or the current intensity can be carried out with the possibilities known in the art, in particular by means of a current clamp, or a Rogowski coil. For this purpose, the current transformer usually has a toroidal core, which is placed around the line or through which the line is performed in order to determine the current flow through the line via a voltage induced by the magnetic field of the line. It has proven useful here, if the toroidal core is designed to be hinged, so that it can be arranged in a simple manner around the line.

Simple handling can be achieved if the display element and the carrier element are designed such that a relative position of the display element to the carrier element in a working position, in particular by a positive connection, is clearly defined. This ensures that incorrect attachment of the

Display element is avoided to the support member by a user, since there is only one way to connect the Anzeigeeiement with the support element.

Appropriately, this may be implemented, for example, that the electrical

Plug is asymmetric ausgeiidet, so that a plugging of the

Display element to the support element only in a relative orientation is possible.

In a preferred variant, the relative position of the display element to

Carrier element clearly defined in a working position by a Formschiuss. This can be achieved, for example, by means of a guide rail on the display element or on the support element, which, when the display element is connected to the guide rail

Carrier element in a corresponding with the shape of the guide rail

Recess, for example, a guide groove, the carrier element or display element is positively inserted. For example, about guide rail and

Guide groove parts of the electrical connector, which are formschiüssig inserted into one another when connecting. It may also be advantageous if a plurality of guide rails are provided in order to specify a given relative position efficiently and easily to a user. It is advantageous if the data processing device is arranged in the display element. As a result, when removing the display element from

Carrier element also removes the data processing device in a simple manner, whereby a particularly high mail is achieved in modularity and flexibility, since in addition to a display element and different data processing equipment to a circuit breaker or connected to the circuit breaker

Carrier element can be attached. In particular

Data processing devices have short development cycles, thereby also a maintainability, especially with regard to software updates or repair, simplified, especially since the data processing device can be removed together with the display element in a simple manner from the support element.

In particular, if sensors for a measurement of electrical variables, such as a current measurement, are arranged on the carrier element and a processing of

Measurement data is performed by the arranged in the display element data processing device, a high degree of modularity and maintainability is achieved because all maintenance-prone parts together with the display element of a

Non-specialist can be solved by the support element.

It is favorable if the display element has a digital display, in particular a display. Thus, determined data can be displayed particularly easily and read by a user. In particular, when the display element has a display, data can be easily seen and displayed in complex form.

It is expedient if the display element has an input device. As a result, a representation of data on the display element can be influenced by a user. In this case, the input device can take place in the form of buttons, buttons, switches, rotary grebs, etc. In particular, a touch operation by means of contact-sensitive surfaces or fields has proven to be particularly robust. It is particularly advantageous if the display element has a touchscreen or a touch-sensitive display. As a result, both a representation of the determined data and a user input is implemented in a simple and intuitive way. It is advantageous if the module has at least one voltage sensor in order to determine an electrical voltage of the line with respect to an electrical reference potential, in particular a neutral conductor. By in addition to the electrical current and the electrical voltage is measured, a power or a

Energy consumption can be determined very accurately. Alternatively, a constant voltage value, for example in Europe about 230 V, is often assumed in order to estimate power or energy consumption in conjunction with a measured current. In particular, when the electrical voltage against a

Neutratleiter is measured as a reference potential, a particularly accurate power or energy consumption measurement can be performed.

It is preferred if the voltage sensor is arranged on the carrier element. Thus, the voltage measurement is decoupled from the display element and thus made particularly robust. A release of the Anzeigeeiementes from the support element can thus be carried out without affecting the voltage measurement, since about a release of electrical voltage contacts is not necessary. In particular, when both the current sensors and the voltage sensors are arranged on the carrier element, a resistant and stable measuring structure is achieved. A particularly simple measuring structure is achieved in that the voltage sensor has an electrical contact, softer with an electrical contact of the

Circuit breaker connectable Is. A simple connection to the conductor is achieved in that the electrical contact of the circuit breaker to which the conductor is connected, also connected to the electrical contact of the voltage sensor in particular can be used for this purpose usually provided on the circuit breaker for fixing a conductor clamping device. This also allows short measuring line paths of the voltage sensor and thus a low-jerk voltage measurement. It is preferred that the electrical contact of the voltage sensor is ausgebiidet as an electrical pin contact, which is rigidly connected to the carrier element and kraftschiüssig connected to the electrical contact of the circuit breaker. This makes it possible in a simple manner, a non-positive connection of the

Carrier element or the Modufes to reach with the circuit breaker. In particular, when the rigidly connected to the support member electrical pin contact is fixed with a provided for a conductor clamping device of the circuit breaker, a non-positive connection is implemented particularly efficient.

In order to achieve a particularly robust construction, it has been proven that the carrier element has a clamping device which is electrically connected to the pin contact of the voltage sensor. For frictional connection of the

Carrier element with the circuit breaker is fixed to the carrier element rigidly connected pin contact with a clamping device of the circuit breaker on the circuit breaker and the conductor to the clamping device of the support element. The Trägereiement is thus part of the line circuit and establishes a contact between the line and circuit breaker ago. This is a simple way a frictional connection of the support element or the module with the

Circuit breaker manufactured and also allows a robust voltage measurement.

To power the module and its components, it is expedient if the module has a power supply, in particular a Schait power supply, for power supply. Thus, a power supply of the module according to the requirements of electronics in the module, such as the data processing device, are tuned. In order to safely supply a power supply even in the event of a power failure, it is advantageous if the module has an uninterruptible power supply. Thus, in addition to a power supply of the data processing device, for example, a power supply of data memories of the module can be sichergestelit to avoid data loss.

It is advantageous if the module has electrical data contacts for data transmission. Thus, for example, measured data and / or by the

Data processing device processed data to be forwarded to an external device. It is expediently provided that a plurality of modules can be connected to one another via these electrical data contacts in order to transfer data between the modules

exchange. For this purpose, usual known in the art

Data connection variants and / or communication protocols are used. In particular, it is provided that a plurality of modules can be connected in series, to exchange data between the modules. This can be done for example via a patch cord or patch cable. In general, it is conceivable to carry this out with a connection variant known to the person skilled in the art, which is suitable for data transmission between devices. In particular fiber optic cables can be used for this, since they allow data transmission with particularly low susceptibility to electromagnetic interference.

It is preferably provided that the module has arranged on opposite sides of the module electrical data contacts for data transmission, so that data can be transmitted between a plurality of modules arranged directly adjacent to each other. This allows several modules to be connected in series without the need for additional data lines. The modules are arranged side by side in such a way that the electrical data contacts of the modules are connected to one another and thus data can be transmitted between the modules. The electrical data contacts for data transmission can be arranged on the carrier element and / or on the display element. If the electrical data contacts are arranged on the carrier element and if a measuring sensor for measuring electrical data, for example the current sensor, is likewise disposed on the carrier, measured data can advantageously be arranged directly between directly adjacent to one another

Carrier elements are transmitted and are represented for example by a arranged on another carrier element display element.

In particular, it is provided that modules are designed such that a fixation of several modules to in an electrical distributor or fuse box immediately adjacent line protection switch leads to directly juxtaposed modules, so that a data transfer between the modules alone by the arrangement of modules directly next to each other is possible. For this purpose, it is expedient for modules, in a front view of a customary electrical distributor or fuse box, to have a width which essentially corresponds to a width of a line protection guard. It is therefore advantageous if the module essentially has a width corresponding to the usual standard widths of line protection switches. A so-called graduation unit in an electrical distributor, which usually has the smallest possible width of a Designates components, usually corresponds to about 18 mm. Preferably, the module thus has a width of one graduation unit or a multiple thereof.

The module or the carrier element and the display element can be designed accordingly for connection to single-pole or multi-pole circuit breakers.

In order to ensure a reliable connection and data transmission between the modules, it is expedient if the electrical data contacts for

Data transmission as electrical press contacts, electrical spring contacts or electrical plug contacts are formed. This is a serial connection or

Data transfer can be achieved solely by arranging the modules next to each other or by attaching them to one another. Additional connection cables are not necessary.

It is advantageous if the module has an input unit, via which an identifier can be assigned to the module, so that the module can be identified during a data transmission. The identifier can be about a numerical sequence, which is assigned to a module via the input unit, so that approximately determined data in the course of

Data transmission can be assigned to a specific module or

For example, a communication between identifiers identifiable modules can be done. For this purpose, the input unit can be designed, for example, in the form of buttons, buttons, sliders, etc. It is also conceivable that an identification automatically takes place on the software side when connecting modules, for example in the form of an assignment of an IP address or a device address, such as a MAC address. In general, a customary identification form and communication variants suitable for the person skilled in the art can be suitable for this purpose, which can be used to communicate or

Data transfer between identified devices allows.

It is expedient if the module has at least one data interface. This makes it possible to produce a communication or data transmission between the module and another device, such as a data memory, or for example to integrate the module in a network structure.

Advantageously, a measuring system is provided for the determination and display of energy quantities and / or powers, which are protected by circuit breakers Lines are transmitted, comprising at least one above dargesteiites module and a Sammeimodul for processing and display of data, which were determined with the at least one module, wherein the collecting module has a data interface for data transmission between the at least one module and the collecting module, a data processing unit for processing the Data and a display device for display. In this way, the data determined and / or processed by one or more modules can be centrally combined, organized, stored and / or displayed. To transmit the data from one or more modules to the collection module, they can be connected by a bus system, for example in the form of patch cords or patch cables. A space-saving design is achieved when data is transmitted wirelessly between the at least one module and the

Collective module are transferable. This can be done for example by radio, Bluetooth or W-LAN. In general, this is conceivable with a person skilled in the art

To carry out a connection variant which is suitable for data transmission between devices. Thus, the determined by Moduie energy and / or

Power consumption of individual circuits is collected and processed centrally. It is preferably provided that the data is managed with a software program on the collecting module and a user via the display device of

Collecting modules, which is designed for example as a display, prepared to be displayed.

In this case, a serial connection of the individual module has proved to be useful, with one module in each case accepting data from another module and forwarding this to another module. The last-ordered module in such an arrangement expediently transmits the collected data to the collection module. It is understood that in such a serial arrangement a first module is not preceded by another module, from which this can take over data, so that this only forwards data to another module. It is also advantageous if the collection module has an input device to allow user interaction. The input device can be done in the form of buttons, buttons, switches, knobs, etc. In particular, a touch operation using touch-sensitive surfaces or fields has proven to be particularly robust. It is particularly advantageous if the display device as a touch screen or is designed as a touch-sensitive display. As a result, both a representation of the determined data and a user input is implemented in a simple and intuitive way. It is preferably provided that the modules are arranged directly next to each other, so that data between the modules via electrical data contacts of the modules are transferable. As shown above in this application, in this way a data transmission between the modules can be carried out particularly efficiently, since additional data lines, such as jumper cables, between the modules can be dispensed with. A transfer of the data takes place directly between electrical

Data contacts on the modules, which are interconnected when the modules are suitably arranged directly next to each other. A data connection of a module with the Sammeimodui can via a data line, such as a

Shunting cable, done.

It is advantageously provided that the data interlacing of the Sammeimodules is designed such that between one immediately adjacent to the collection module

arranged above illustrated module and the collecting module via electrical data contacts of the Moduies and the data interface of the Sammeimodules data are transferable. As a result, data can be exchanged in a simple manner according to the principle outlined above between a plurality of modules arranged directly next to one another and also between a module and the collecting module. Appropriately, it is accordingly provided that at least one module and a

Collection module are arranged directly next to each other, so that data can be transmitted via electrical data contacts of the Moduies and the data interface of the Sammeimodules. This is by merely arranging modules and a

Sammeimodules unmitelbar side by side allows data transfer between the modules and the Sammeimodui.

Simple handling is achieved if wireless data transmission is provided between the modules or between the modules and the collection case. This can be done for example by radio, Bluetooth, W-LAN or W-LAN print. Suitably, the module © or the Sammeimodui this radio, Bluethooth or W-LAN modules.

A functionality of the collection mode can be increased by the fact that the

Collection module has a communication device to transmit data to an external device. As a result, for example, measured and / or processed data, such as a current energy consumption, can be transmitted to the external device. For this purpose, the collecting module expediently has further interfaces or sockets for data transmission. For example, these can be USB, FireWrite, RS-232 or RJ connection jacks. It is also preferable to provide wireless data transmission to an external device. Suitably, the collection module may have a radio module for this purpose. This can for example be designed as a WLAN module, LTE module or Bluetooth module. Thus, for example, management circuits of a home system can be monitored even in the absence of a user from a distance. The module can also advantageously have such a communication device in order to transmit data to an external device. As a result, data can be issued flexibly, depending on the application, directly from the module or else via the collection case.

Advantageously, at least one data store is arranged in the collection case, in which, for example, the aforementioned data are stored. Appropriately, such a data memory is designed such that it can be read out or described within the scope of a communication with one or more modules or an external device. With a module according to the invention or a measuring arrangement according to the invention, the energy consumption or a performance of an entire electrical

House installation, broken down into management circuits, monitored and evaluated. The energy consumption of a circuit can be directly connected to the module at

Display element, but also on a Sammeimodui, especially in comparison with a power consumption of other circuits, are displayed. In particular, this may result in a user in the case of a predefined event, such as a

StromFail or exceeding a certain defined limit value of a measured or determined electrical variable to be notified. Further features, advantages and effects emerge from the following

Plug connection is releasably connected to the carrier element 2. This is one

This allows different Anzeigeeiemente 3 simply and flexibly changed between carrier elements 2 and arranged on circuit breakers 4. On a side surface of the display element 3 can be seen, in addition

electrical data contacts 8 for data transmission, so that between immediately juxtaposed modules 1 and display elements 3 data are transferable. For measuring an electrical current of the line, a current sensor is provided, which has a current transformer 5 in order to determine the current or the electric current inductively. For this purpose, the current transformer 5 has a toroidal core, through which the line is guided in order to determine the current intensity via a voltage induced by the magnetic field of the line. The measured electric current or the current is processed by a data processing device to calculate the electrical power or a consumed amount of energy. For this purpose, the determined current is usually combined with an assumed or measured electrical voltage. Appropriately, it is therefore provided that the support element 2 has at least one voltage sensor, wherein an electrical contact of the

Voltage sensor is connected to an electrical contact of the circuit breaker 4. The electrical contact of the voltage sensor is designed for this purpose as an electrical pin contact 10, which is rigidly connected to the carrier element 2 and frictionally connected to the electrical contact of the circuit breaker 4. As a result, a frictional connection of the support element 2 and the module 1 is achieved with the circuit breaker 4 in a simple manner. Detailed illustrations of the display element 3 and of the carrier element 2 or different embodiments of these are given below in FIGS. 2 to 6. 2 shows a carrier element 2 of a module 1 according to the invention, which is designed for connection to a single-pole circuit breaker 4. The

Support element 2 has an angled formed shape, so that this, as shown in Fig. 1, is formed corresponding to an upper or lower end of a conventional circuit breaker 4. This allows the Trägereiement 2 in

Plug receptacles 6, for receiving arranged on a display element 3 plug elements 7, is ausgebiidet, by which a Anzeigeeiement 3 detachably connected to the support member 2 is connected. In order to ensure that an incorrect attachment of a display element 3 is avoided on the support member 2, it is also provided that a Reiativposition of the display element 3 to the support member 2 is clearly defined in a working position by a form fit. For this purpose, a guide groove 9 is arranged on the carrier element 2, in which, when the carrier element 2 is connected to a display element 3, a guide rail 16 arranged on the display element 3 can be inserted in a form-fitting manner. Suitably, the guide groove 9 is arranged asymmetrically on the carrier element 2 for this purpose. In order to implement a kraftschiüssige connection of the support element 2 on the circuit breaker 4 in a simple manner, an electrical contact of the voltage sensor is designed as an electrical pin contact 10, which is rigidly connected to the support member 2 and frictionally connected to an electrical contact of the circuit breaker 4. The carrier element 2 also has a clamping device, which comprises a clamping bush 11 with a clamping screw, on which the electrical line can be fixed and electrically be connected and which can be electrically connected to the

Pin contact 10 is connected. For frictional connection of the carrier element 2 with the circuit breaker 4 is rigidly connected to the Trägereiement 2 pin contact 10 with a clamping device of the circuit breaker 4 am

Circuit breaker 4 and the conductor fixed to the clamping device of the support element 2. Thus, the carrier element 2 is part of a line circuit and establishes an electrical contact between line and circuit breaker 4. In order to facilitate mounting of the pin contact 10 in the clamping device of the circuit breaker 4, which usually has a clamping screw, is a

Passage opening 14 is arranged in the carrier element 2, so that accessibility to the clamping screw of the circuit breaker 4 is given. There is also one

Through hole 15 provided in the support member 2 to any measuring lines along the support member 2 up to the connector or to a

To lead display element 3.

To be able to influence a display of data on the display 17 by a user, a push button 18 is provided as an input device. Furthermore, it can be seen in FIG. 5 that the module 1 has electrical data contacts 8 arranged on opposite sides of the module 1 for data transmission, so that data can be transmitted between a plurality of modules 1 arranged directly next to one another. As a result, a plurality of modules 1 can be connected to each other in series, solely by arranging them directly next to one another. In order to be able to assign determined data to a specific module 1 or to a specific line within the context of a data transmission, the display element 3 has a Input unit in the form of multiple DtP switches 19 on. In this way, an identifier can be assigned to a module 1 or determined data by a user, for example for the assignment of the data to a specific line circuit. FIG. 6 shows a display element 3 of a module 1 according to the invention, which is designed for detachable connection to the carrier element 2 represented in FIG. 4.

FIG. 7 shows a collecting module 20 according to the invention for processing and displaying data which has been determined using one or more modules according to the invention. The collecting module 20 has a data interface 21, via which data from one or more modules 1 can be transmitted to the collecting module 20. In this way, the data determined and / or processed by modules 1 can be centralized

be merged, organized and stored. The collection module 20 also has a screen 22 to depict data to a user. Also visible is an input device in the form of multiple buttons 23 to facilitate user interaction. In order to transmit data to an external device or to communicate with an external device, further interfaces are provided on the collection module 20, in particular, FIG. 7 shows RJ connector sockets 24 in order to transmit data, for example via a wired network. Furthermore, connections 25 for a power supply are also shown.
