Description

Cluster communication equipment
Technical Field
The invention relates to a cluster communication device.
Background
It is well known that electrical engineering requires overvoltage protection devices, for example for power grid protection applications.
Overvoltage protectors typically have local status display readings. In addition, some overvoltage protection devices also have integrated communication devices that can communicate their error reports to a more remote location.
However, overvoltage protection is also increasingly required in other fields, for example in the field of telecommunications, measurement, control and regulation technology.
Since complex networks are often constructed in these areas, it is often not possible to replace the overvoltage protectors while they are in operation, regardless of the equipment being taken out of operation.
Therefore, the user is faced with the problem that: at initial installation it is necessary to decide whether to choose an overvoltage protection device with or without a telecommunication device.
Systems have therefore been proposed in the past in which overvoltage protection devices are scanned by means of a light barrier, through which a change in the optical properties of the light beam indicates a particular state.
However, such a system has proven to be disadvantageous because it requires additional installation space on the side of the overvoltage protection device, for example for the head module and/or the central module, so that, for example, the attachability in the switch cabinet would not necessarily be possible, but would also make rewiring necessary. Furthermore, there are often problems in that: depending on the arrangement of the light path, respectively, there is a risk that wires or dust enter the light path and thus indicate an error state.
Disclosure of Invention
Based on the above-mentioned circumstances it was an object of the present invention to provide a solution, a group communication device (1), comprising a plurality of overvoltage protectors, the overvoltage protection devices are arranged side by side and are respectively correspondingly attached to the remote communication module, said telecommunications modules having corresponding connection means for mounting to an overvoltage protection device, a plurality of said telecommunications modules also being arranged adjacent to each other side by side, the telecommunications modules have contact means contacting each other on adjacent sides between them so that adjacent telecommunications modules are electrically connected in series with each other, when one overvoltage protection device is in an overvoltage triggering state, the corresponding remote communication module interrupts the electrical connection with the adjacent remote communication module or interrupts the electrical connection among a plurality of remote communication modules adjacent to the remote communication module.
Wherein the connecting mechanism is a snap connecting mechanism with a locking function.
The remote communication module is provided with an interrupt responder for responding the displacement change of the indicating device.
The plurality of telecommunication modules are respectively provided with connecting terminals, the connecting terminals are respectively connected with the contact devices of the telecommunication modules, and the connecting terminals are used for being connected with an external power grid.
The present invention does not cause any equipment downtime and allows the user to decide whether and when it is desired to activate the remote communication device.

Detailed Description
Fig. 1 shows an overvoltage protection device which can be arranged next to one another
Figure BDA0001395590290000032
And a telecommunication module FM according to an embodiment of the invention1A schematic perspective view in an unassembled state. A plurality of overvoltage protectors and telecommunications modules can then be arranged side by side with one another in order to enable electrically integrated telecommunications, for example as shown in fig. 8.
Wherein a plurality of overvoltage protectors are arranged side by side
Figure BDA0001395590290000033
Each overvoltage protection device in the series has a respective associated telecommunications module FM1、FM2. Multiple telecommunications modules FM1、FM2Each having means for mounting to an overvoltage protection device
Figure BDA0001395590290000034
And a corresponding connection mechanism.
Fig. 1, for example, shows an embodiment for push-on/push-in, in which corresponding recesses correspond to corresponding projections, so that the telecommunications module can be detachably placed on the overvoltage protection means in some cases at a later time.
In fig. 2 and 3, an overvoltage protection device is provided
Figure BDA0001395590290000041
And an associated telecommunications module FM1In the side view of the same, which illustrates the situation, the assignment is made by pushing onto the overvoltage protection means. It is particularly advantageous if the overvoltage protection device
Figure BDA0001395590290000042
With an associated telecommunications module FM1As shown in the figures, are adapted to each other, i.e. to the respective constructional dimensions, for example the same planar dimensions.
As shown in fig. 5, the telecommunications module FM1、FM2Can also be arranged next to one another, wherein the telecommunications modules FM1、FM2At the moment of communication with another telecommunications module FM1、FM2With electrical contact means KM contacting one another on adjacent sides1.1、KM1.2；KM2.1、KM2.2So that adjacent telecommunications modules FM1、FM2May be electrically connected to each other.
For this purpose, the contact means can be designed, for example, as bent sheet metal elements, see fig. 4 and 5 in detail, so that the sheet metal elements bent at the sides form a contact spring-like connection when arranged next to one another. For this purpose, for example, the contact device KM1.1、KM2.1Can be designed as a plane on the side of the telecommunications module, while the contact means KM1.2、KM2.2Is formed as a circular arc surface at the other side of the telecommunications module toGood contact is made by elastic forces when contacting each other and thus electrical contact is established.
If a plurality of telecommunications modules are thus arranged in a row with respect to one another, an (interruptible) electrical connection, i.e. a series circuit, is formed between the telecommunications modules.
In overvoltage protectors, e.g.
Figure BDA0001395590290000043
In the event of overvoltage triggering, the associated telecommunications module FM is assigned to it2The telecommunications module FM adjacent to its side will be interrupted1Or adjacent to both sides thereof1、FM3Are electrically connected in series. Thus, a signal can be derived from the interruption of the electrical connection, which signal indicates an interruption in one or more locations.
Because the telecommunications module FM1，FM2、FM3Can be subsequently placed in the overvoltage protection device
Figure BDA0001395590290000044
In this way, the subsequent installation can be carried out without investment. Furthermore, the existing wiring does not have to be removed, and in addition no installation space is required on any side.
In an advantageous design, the connection is a snap connection with a locking function for easy mounting. A more reliable (and in each case design-dependent, re-separable) connection between the overvoltage protection device and the telecommunications module can thereby be provided. This is advantageous in environments with vibrations, since then an unintentional loosening of the telecommunications module (and thus an isolation of the electrical series circuit) can be avoided.
In an embodiment of the invention, the overvoltage protection device
Figure BDA0001395590290000051
Each having at least one respective mechanical indicating device Z1In the event of a fault (overvoltage of the voltage protection device)Triggered) causes a displacement change of the indicating means for indicating a fault condition of the overvoltage protection device.
Mechanical indicating device Z1For example, the tongue is displaced causing the reading window to change. The remote communication module FM1、FM2With means for responding to an associated overvoltage protection
Figure BDA0001395590290000052
Of the mechanical indicating device T1(that is to say the responder T1For responding to a change in displacement of the indicating device). The interrupt-responder is resiliently arranged into a display window, being pushed up/moved by a mechanical tongue of the interrupt-responder in case of a fault, thereby interrupting the electrical contact within the telecommunications module. For example, the interruption responder is an electrical tongue that can act directly on the telecommunications module, thereby interrupting the electrical contact between the contact means of the telecommunications module arranged at the side.
That is, mechanical movement of the mechanical display may be coupled to the telecommunications module. Alternatively or additionally, it is of course also possible to provide, for example, an electrical contact of each overvoltage protection device to the telecommunications module, by means of which the electrical connection of the telecommunications module can be interrupted. This is illustrated, for example, in fig. 6 in the operating state and in fig. 7 in the fault state. That is, in an operational state without the telecommunications module, the mechanical movement readings are taken optically, and in the case of the telecommunications module, the display readings can be taken directly from "mechanically moved". That is, by mechanically moving, wiring investment is minimized.
As shown in fig. 1 to 3, 5 to 7 and 8, may be additionally specified. For example a first telecommunications module FM1With a connecting terminal FK1Second telecommunications module FM2Also having another connecting terminal FK2So as to provide for FM communication with each telecommunications module1、FM2Each contact device KM1.1、KM1.2；KM2.1、KM2.2To an external power grid. That is to say, by the measures described above, a series circuit can be simply introduced/derived which does not require any lateral electrical contact.
In addition, by thus connecting different ranks, cluster telecommunications across different ranks of switchboxes or across gaps in a row may also be achieved. That is, the above solution is very flexible and cost-controllable.
Now if a fault situation occurs, the location of the fault can be quickly defined, for example by extraction on other connecting means, so that troubleshooting has proven to be extremely simple. Alternatively or additionally, it is of course also possible to carry out a single query by means of each further connection device.
By means of the invention, a device is provided which can be fitted/snapped into an overvoltage protection
Figure BDA0001395590290000061
On a telecommunications module FM1Which, together with the contact device KM1.1、KM1.2Together providing telecommunications functionality.
Wherein the remote communication module FM1Is and overvoltage protection device
Figure BDA0001395590290000062
Connected, e.g. clipped, thereto. By means of said telecommunications module FM1Side contact device KM1.1、KM1.2Is in contact with one or more further telecommunications modules FM2、FM3In series, the connection to the adjacent module is established almost automatically. The individual telecommunications contacts are thus switched on serially by the concatenation. The outermost telecommunications modules in a row are advantageously in contact with the connection lines. All the associated overvoltage protectors are then included in the cluster telecommunications.
The telecommunications module furthermore has spring contacts which bear against indicator elements present in the overvoltage protection device and are closed thereby in the operating state. The closed state enables series connection with adjacent modules.
If the spring contact is opened, the path is isolated, for example by triggering an overvoltage protection, so that the series circuit is interrupted and a changed state can be detected.
