Background technology
Typical electric energy is not according to required and produce.Therefore after producing, must convert high voltage to, and after distributing and/or at that time so that transmit, generally the majority of network node and at different levels in, meeting convert low-voltage to from high voltage once more.The fine and closely woven distribution guiding low voltage power supply network of energy is to different end users, and it has a tree-like construction to reach this purpose.Suppling signal is distributed by root, promptly by central point, for example in a uptown electric substation, is dispensed to other zone, residence via most branch lines.In the zone, residence, network is divided into indivedual residences once more and reaches, in the residence, and inferior each socket and other the network interface of being divided into.
Known information such as telephone relation, the fax backup, digital code informations etc. can transmit via the low voltage power supply network.For this purpose, information is encoded and in a known way, for example via frequency modulation(FM), is modulated to the high-frequency carrier signal.This information is to input to the low voltage power supply network from transmitter, and is exported once more by receiver, then decoding.In this way, utilizing the information transmission system of a power supply network is to be described in the A95/29537 as WO.
For obtaining short as far as possible access path, transmitter and the receiver power supply network that is connected to close to each other as far as possible.But so make itself and the difficulty more of communicating by letter that is connected to another network branch line station.In addition, this needs the Network Transmission passage of a plurality of dispersions, is to and from other communication networks for message transmission.
Invention is described
The present invention seeks to providing the circuit arrangement that the front is at first mentioned, the problem that it can avoid prior art to exist, and particularly in power supply network and be to and from the message transmission of other communication networks, allow to have energy efficiency and cost-efficient message transmission.
The solution of this purpose is the characteristic definition by claim 1.According to the present invention, the low voltage power supply network debouches the low voltage power supply network that comprises network node for input and output high frequency information signal from least one master station.Network node, for example a transformer or power distribution station, have a power distribution equipment in order to the distribution network electric current to most supply lines.Master station is to be connected to power distribution equipment, and information signal can be imported and the output LOW voltage power supply network via master station.
Information signal is to be transmitted between master station and the most subscriber station, and the subscriber station that the typical case is positioned at low voltage power supply network branch line zone is to connect, for example, to the socket in a residence, if or distribution box is arranged within doors, then be connected to the low voltage power supply network.Master station itself at first with subscriber station communications, secondly, the communication between control and monitoring user station.In addition, message transmission is to and from other communication networks, as telephone network or the Internet, can finish via master station.
Configuration allows all subscriber stations in a circuit according to the invention, via the same branch line that is connected in the low voltage power supply network or not even with the turnover of the master station of branch line.But by the center, master station also can pass in and out in rightabout via all subscriber stations.The single network transmission channel is located in the master station, therefore, can further fully allow all users, and transmission information in addition passes in and out other communication networks.
But be not only to be to connect via master station to transmit information signal to the low voltage power supply network, master station also can be through connecting simultaneously from low voltage power supply network supply electric power thus.
Master station is preferable to be capacitively coupled to power distribution equipment.The high frequency information signal be via, for example, a high pass filter is from power distribution equipment input and output.High pass filter can prevent low frequency in addition but the high-energy mesh current enters the information path of master station.
For the distribution network electric current, power distribution equipment has electric current input, a distributor and the output of at least one electric current.With the mesh current that distributes is to reach distributor via the electric current input.The electric current output of telling via distributor is dispensed to indivedual supply lines with mesh current then, and for this purpose, indivedual supply lines are to be connected to an electric current output separately.
In the situation of polyphase network electric current, distributor, for example a bus-bar is to be designed to have suitable number of poles.For example, in all cases, for the three-phase and the neutral conductor of three-phase network electric current, each line has a special-purpose bus-bar.In order to allow an electrical load or a subscriber station to be connected to a supply line, reach and allow transmission one information signal on supply line, it must have two electric conductors at least, promptly so-called neutral conductor and at least one phase conductor.Thereby each electric current output of power distribution equipment also need have at least two electric conductors, is the suitable utmost point that is connected in distributor separately.
Communicate by letter with which and which bar supply line is to be connected to subscriber station according to subscriber station expection, have most selections can so connect master station to the low voltage power supply network.
In preferred embodiment of the present invention, master station is to be connected to distributor.
In order to connect master station to distributor, the latter has the two poles of the earth at least, and one is that neutral conductor and at least one are phase conductors, and master station has at least two to connect contacts.Master station is to connect the utmost point that the contact correspondence is connected to power distribution equipment by one in each situation.
In second concrete example of the present invention, master station is at least one electric current output that is connected to power distribution equipment, and promptly distributor is in effective downstream of subscriber station direction.
Therefore all users that are connected in identical branch line can have no the turnover of difficulty from master station.Even but the subscriber station that is connected in different branch lines also can pass in and out via distributor, or, simultaneously the identical information signal is sent to different supply lines from being connected in the master station of most electric currents outputs.Equally, can be applicable to turnover property certainly, and be applied to and the communicating by letter of other network users from subscriber station to master station.
In the preferable variation of this concrete example, most master stations are to be connected in one separately, and a supply line only.Therefore, different information signals can transmit on each different branch line.
Master station has at least two in turn and connects contact, and electric current output comprises at least two electric conductors, promptly so-called neutral conductor and at least one phase conductor.Master station is an electric conductor that is connected to the supply line in the individual cases by the connection contact arrangement correspondence in the individual cases.
In another circuit arrangement, preferable at least two electric currents that are connected to of master station are exported, and its handover configurations is to be connected between master station and the electric current output.Handover configurations is to be designed to master station can select to be coupled to electric current output or extremely most simultaneously electric currents output.An information signal can select to be coupled to one or a plurality of supply lines of while from master station.
Illustrate that as top each electric current output comprises at least two electric conductors.For avoiding damaging, or limit this kind damage at least, in the failure condition as short circuit, the electric conductor of electric conductors or all supply lines is effectively to protect its overcurrent fault by an overcurrent release individually.Overcurrent release, promptly protective device is to place, and for example directly is adjacent to the junction that electric current exports distributor to.
Interference may cause the negative effect of message transmission, understands the result because of the switching degree, and is caused by the echo or the cross-talk of other supply lines.In order to suppress this kind interference, one or more electric conductor of electric current output is preferable to be connected to distributor via a low pass filter.But this kind low pass filter not only suppresses external interference, can prevent that simultaneously the information signal that has inputed to power supply network from propagating in unexpected direction.
Electric conductor via an overcurrent release be connected to distributor and, simultaneously, under the situation via a low pass filter, the preferable overcurrent release that is integrated in of low pass filter.This promptly represents low pass filter, for example has a suitable induction coil, be integrated in the protective device housing or, more generally, low pass filter and overcurrent release are to be contained in the same housing.This promptly is illustrated in, and installation one low pass filter does not involve extra complexity in the existing system, only needs to replace its old protective device with the new protective device of an integrated filter and gets final product.Select the inductance of inductor, its impedance is had no effect for the low frequency signal of for example mesh current is several, but for the high-frequency signal of for example information signal, or corresponding interference signal then has very big influence.
For transfer of data via the low voltage power supply network, just as, having 230/400V power supply network less than the network of 1KHz, the information signal frequency is preferably between 1MHz and the 60MHz.This expression information is to be modulated on the carrier wave in the carrier frequency between 1MHz and 60MHz.
In the preferred circuit configuration, except at least one master station, most subscriber stations are to be connected to the low voltage power supply network.
In this situation, master station be effectively be designed to subscriber station on the one hand can with at least one master station exchange message signal, and on the other hand also can be via the mutual interchange information signal of at least one master station.
Message transmission come and go a master station or a subscriber station to or from outside (with respect to the low voltage power supply network) user, except the low voltage power supply network, master station is effectively to be connected to other communication network.
One has the method for claim 15 characteristic, the information that is used for transmitting or receiving master station that can be preferable via a low voltage power supply network, this low voltage power supply network has a network node with power distribution equipment, and wherein master station is to be connected to power distribution equipment in network node.
Power distribution equipment in network node is to be used for the distribution network electric current to most supply lines.Network node is, for example, and the electric substation in a supply zone, electric energy to a residence, or the power distribution station in the indivedual houses of a supplying energy to the street.
When the information of transmission, produce the high-frequency signal that capacitive character inputs to power distribution equipment by information being modulated into a high-frequency carrier signal at master station.The rest may be inferred, when master station receive one transmit via the low voltage power supply network information signal the time, signal is from the output of power distribution equipment capacitive character, and information is to feed back from the information signal demodulation.
With the information that transmits is that the typical case is produced by an information terminal, and a computer that is connected to master station or subscriber station for example generally is decoding after coding and the demodulation before modulation, and the last further processing according to the needs of receiver.
The method can utilize the circuit arrangement type that has illustrated to carry out especially.
One information signal inputs in the low voltage power supply network via two electric conductors of electric current output, particularly greater than the information signal under the frequency of 1MHz, available different modes is propagated: be connected directly on the supply line of electric current output, from then on electric current output via distributor to other electric currents output, or even via distributor in the electric current input direction.Be back to other electric currents output from electric current output via distributor, or even to the signal path of electric current input, generally be all unexpected.So therefore preferable at least one at least two electric conductors of corresponding current output of low-pass filtering carried out, and utilizes the low pass filter that is connected between distributor and the master station tie point, and the filtering information signal.Simultaneously, this low pass filter also can be used to suppress unexpected interference, reaches from distributor on the one hand and exports from electric current on the other hand.
Perhaps, if master station is to be connected in distributor, the information signal that may be inclined to input is only transmitted via particular route.Ding Wei low pass filter in this situation also of great use in this way.In addition, in this case, the input of the electric current of power distribution equipment also can be provided with a low pass filter.
By utilizing most master stations, each is connected to one or most electric current output, can be connected in most subscriber stations of different branch lines simultaneously with different information signal supplies.In this situation, carry out low-pass filtering in the electric conductor between indivedual tie points of distributor and master station equally, interfere with each other to prevent information signal.
For avoiding contingent damage, for example, in the incident of short circuit or other faults, electric current output, or indivedual electric conductors of electric current output add and should protect for the overcurrent between distributor and the master station.This is between distributor and master station tie point, inserts an overcurrent release at least one electric conductor.
One master station, when being used for importing and exporting the high frequency information signal that debouches a low voltage power supply network, explanation as described above is with respect to a transmission/receiving system that additional functionality arranged.This kind transmission/receiving system is to be used for input and output electric signal, and capacitive character debouches power supply network.Its additional functionality comprises, and for example, coordinates the communication between other transmission/receiving systems.
The purposes of this master station is to be used for importing and exporting a high frequency information signal, debouch that the low voltage power supply network is preferable to be reached as for the power distribution equipment of the network node that uses in the low voltage power supply network via connecting master station, so that distribution network electric current most supply lines extremely.
Further effectively the combination of concrete example and characteristics of the present invention will be more clear by claims of following detailed description and globality thereof.
