Definitions
- the invention first relates to a device for inductive coupling of electrical signals (PLC signals) to a current-carrying, in particular power supply line provided with an insulating jacket, if necessary according to the preamble of claim 1.
- PLC signals electrical signals
- the term signal coupling is intended to be bi-directional in the sense of the invention Enable data transfer, i.e. both the uploading of Signals on the power supply line as well as decoupling or Decouple those to be transmitted on the power supply line Signals.
- the aim of the invention is to further develop the coupling point, wherein the type of signal coupling is inductive.
- Inductive signal coupling means that coupling indirectly through magnetic excitation of a magnetic Element is done and not in a capacitive way or by direct electrical contacting of the voltage supply line takes place.
- folding ferrites are regularly additional capacitive components are provided, so that at these intended coupling points only in a very narrow-band resonance range, which is caused by the Inductance of the folding ferrite together with the capacitive component is determined, signal transmission is possible. After all, they can Folding ferrites should not be too bulky.
- the object of the invention is a device according to the Develop the preamble of claim 1 such that it improves inductive coupling of electrical signals to a power supply line allows.
- the invention solves this problem with the features of claim 1, especially with those of the identification part, and is marked accordingly by an essentially ring-shaped one, of at least two parts Composable clamp made of nanocrystalline or amorphous, ferromagnetic Material.
- the principle of the invention thus consists first of all in a clamp made of a special material. Unlike ferrites, which the desired magnetic properties for an optimized coupling of signals to a power supply line are nanocrystalline or amorphous, ferromagnetic materials for this in particular Way suitable.
- Such materials which are very expensive, in particular using rapid solidification technology by casting a melt with extremely rapid cooling, can be made directly into a thin strip, are for example at the company vacuum melt under the trade names Vitrovac and Vitroperm available. For example, more information is available at www.vacuumschmelze.de.
- Nanocrystalline or amorphous, ferromagnetic materials offer a particularly high initial permeability, which can be, for example, in the range from 20,000 or 40,000, but also above.
- a high initial permeability ie a maximum ⁇ r with initial magnetic excitation by a current for the first time (i.e. the slope of a new curve in a BH diagram), is of particular importance.
- nanocrystalline expresses a special order characteristic of the ferromagnetic material, and describes the fact that in this material has no long-range order or crystal structure. This amorphous state corresponds to the material state immediately after Shock freezing. Through a subsequent heat treatment or tempering process finds a change in state from amorphous to nanocrystalline State instead.
- nanocrystalline means that the grain sizes of the magnetic areas in the nanometer range (middle Diameter 10 to 20 nm). Nanocrystalline materials are above it usually characterized by a two-phase structure in which a fine crystalline grain with the above mentioned grain diameter in one amorphous residual phase is embedded.
- the initial permeability plays as a physical quantity and measurable characteristic of these materials special role. For example, by using such materials with such high initial permeabilities as mentioned above in one assumed minimum coupling factor of - 3 dB and a lower one Transmission frequency of 2 MHz still an inductance L of the device from 4 ⁇ H can be reached.
- a second aspect of the invention provides that the clamp nanocrystalline or amorphous, ferromagnetic material from at least is composed of two parts and is ring-shaped.
- the power supply line on their Encompasses the outer surface, and due to the fact that it can be separated or dismantled or assemblability can be easily assembled, namely on the power supply line is attachable.
- the assembly and disassembly of the device according to the invention can therefore be carried out by specialist personnel who are not the must have the knowledge required for stripping.
- fasteners such as Screw connections may be provided.
- a voltage supply line in the sense of this invention for example also understood a medium-voltage line that has an inner, Electrically conductive core and an outer, electrically insulated shield, for example from a mesh of metallic threads.
- Coax cables can with the device according to the invention The signals are coupled directly to the shield, and a Forward digitally through the shield. But it can also be provided be a signal coupling to the shield first and the signal for forwarding through a special circuit to transmit the inner soul, i.e. the core of the coax cable.
- the clamp offers due to their geometric structure also the possibility of a Signal coupling to a voltage supply line also on such Make places where the power supply line is strong is curved. Because of a clamp-like design with a preferred the radius of curvature only plays a subordinate role Role.
- the clamp is made of two essential semicircular parts assembled. This makes possible on the one hand an arrangement with a small number of components, so that the manageability is facilitated. On the other hand, with this configuration only two separating cuts, for example along a common one Diameter plane of a substantially circular band winding required so that the tape wrap is minimally damaged in its structure becomes.
- the clamp is formed from a continuous annular band wrap, the is divided into at least two parts.
- This embodiment of the invention allows, among other things, the use of conventional, commercially available circular tape winding made of nanocrystalline or amorphous, ferromagnetic Material.
- the Tape wrap cut at least along one plane.
- a cut along one plane, especially along a common diameter plane, offers the possibility of reducing the risk of damage to the internal structure of the To keep tape wraps low.
- the tape wrap is impregnated, especially before cutting like a potting compound.
- a potting compound offers the possibility of the tape wrap in its structure before the Reinforcing cutting, especially stiffening.
- a cutting one such reinforced tape wraps create a condition in the first place of the tape wrap, by separating it into two parts.
- the potting compound Depending on the delivery condition of the tape reel, it can be placed in open spaces, especially in the pores of the tape roll and in spaces between penetrate the layers.
- the potting compound essentially on the outer surfaces for example on the Outer lateral surface and arranged on the ring end faces of the tape roll is and corset-like this surrounds the tape wrap.
- the Potting compound a resin, in particular a thermosetting epoxy resin or temperature-resistant polyester resin.
- This embodiment of the invention enables the use of inexpensive and commercially available casting compounds with particularly good workability and manageability.
- the Tape wraps have been vacuumed before impregnation and the Potting compound in free spaces, e.g. B. penetrated into pores of the tape roll.
- Providing vacuum before impregnation offers the possibility of one Particularly good and safe corset formation through the potting compound.
- the clamp in the assembled state in the joint area two each adjacent parts a thin gap.
- the joining area in other words, the area in which two adjacent parts are almost adjacent to each other bump is according to this advantageous embodiment with a thin, in particular defined gap.
- the gap can be, for example Have a width of the order of 10 ⁇ m and with air or paper, optionally also be filled with an adhesive strip. It is important that the Gap is filled with a non-magnetic and non-conductive material. In particular In this context it is important that the cut surfaces of the tape wrap in the assembled state of the clamp not directly against each other lie. In this context, it is also advantageous that the cut surfaces are particularly smooth or flat and do not form fringes show that would be disadvantageous for magnetic reasons.
- the invention also relates to a method for processing an essentially annular tape winding made of nanocrystalline or amorphous, ferromagnetic material according to the preamble of the claim 16th
- tape wrap usually represents the final shape, i.e. the finished processed state of the tape reel.
- the known tape reel are usually transported in toroidal containers and are used as storage chokes. If necessary, a sintered material can also be used here can also be attached.
- the object of this invention is a machining method according to the preamble of claim 16, which provide the use of the processed tape roll in a device for inductive Coupling of electrical signals to a current-carrying, in particular power supply line provided with an insulating jacket if necessary allows.
- the principle of the invention is therefore essentially one conventional, finished, substantially ring-shaped tape winding, which a variety of winding layers nanocrystalline or amorphous, ferromagnetic Material is first to be placed in a container. Subsequently a potting compound can be introduced into the container with which the Tape wrap is impregnated or soaked.
- the potting compound is especially if according to an advantageous embodiment of the invention Container is evacuated and after inserting the tape wrap in the Container and before impregnating the tape roll with the tape roll a vacuum is applied due to the existing vacuum in the Free spaces, that is to say sucked into the gaps or pores of the tape roll. Even if no vacuum is applied, there is always Possibility of stiffening by attaching the sealing compound ensure that at least the surfaces, i.e. the outside of the tape wrap covered with casting compound. However, the application of a vacuum is clear more advantageous.
- the tape wrap After impregnation, the tape wrap can be divided into at least two parts separated, for example cut. In principle, it is sufficient if the tape wrap impregnates at least in the area of those places at which a separation subsequently takes place.
- the machining method according to the invention is one possibility ready the tape wrap first with a corset in the form of the potting compound to provide, which stiffens the tape roll so that it can subsequently be separated.
- Applying a vacuum to the Tape wrap before the impregnation process step ensures a particularly close concern of the corset-like casting compound or for a some intrusion, if necessary.
- the originally very brittle and not easily processed, not for subsequent processing suitable and not intended nanocrystalline or amorphous, ferromagnetic In this way, material is brought into a form in which the tape wrap is separable.
- the device designated 10 in its entirety in the figures for the inductive coupling of electrical signals is first used 1 explained as follows:
- a signal generator / signal receiver module indicated only schematically 11 sends or receives electrical signals, particularly high-frequency ones Signals. Usually they are signals of a frequency range approximately between 2 and 20 MHz in which data is transmitted.
- the electrical signals are to be loaded onto a voltage supply line 12 are or tapped from this line 12, so that a Data transmission can be carried out via the power supply network can.
- the voltage supply line 12 is, for example, a high-voltage line, a medium voltage line or a low voltage line, on the typically AC voltage in the kilovolt range with a low one Frequency, for example 50 to 60 Hz is present. Because the signals are high frequency signals signal transmission and provision are impaired of electrical power through the power grid, which is primary the goal of the power grid is not.

- the schematic, perspective view according to FIG. 2 becomes clearly that the clamp 13 is a substantially circular body. Between the inner peripheral surface 36 of the clamp 13 and the outer surface 37 of the voltage supply line 12 (Fig. 1) is an annular Free space 38, the arrangement and size of which is not critical. critical is, however, that a signal line 14 that is connected to the signal generator / signal receiver module 11 is connected, in the manner of a half winding grips the clamp 13 and for this purpose passes through the annular space 38.
- High-frequency signals that are on signal line 14 call a magnetic excitation of the clamp 13 because it is made of ferromagnetic Material exists, whereby the material itself will be detailed later is received.
- the magnetic excitation gives the clamp 13 then on to the power supply line 12, namely in Form in turn of electrical impulses (voltages).
- the clamp acts thus in the manner of a transformer, the signal line 14 and the Power supply line 12 is a primary winding and correspondingly one Represent secondary winding of a transformer with the number of windings 1.
- the signal line 14 only grips the clamp 13 half a winding and the power line 12 due to their large, approximate infinite length the clamp 13 also only in the manner of a half Winding.
- a consideration such that power line 12 and signal line 14 actually represent an entire winding with this geometry allowed.
- the broadest possible bandwidth is desired Transmission range, that is, only a very low attenuation of Signals in a wide frequency range. In other words, is a uniform coupling factor over a large frequency range advantageous.
- the clamp 13 is made of nanocrystalline or amorphous, ferromagnetic material.
- a soft magnetic material is an alloy called a soft magnetic material becomes.
- soft magnetic means that the Hysteresis curve, i.e. the curve in a B-H diagram, is a special one represents a narrow hysteresis loop. The narrower the hysteresis loop, that is, the smaller the area between the two branches that a or movement (e.g. an alternating current through the voltage supply line 12), the lower the electrical losses, which mean a conversion into thermal energy.
