Definitions
- the invention relates to a method for supplying electricity to a power consumer from a store for electrical energy and to a power store suitable for carrying out the method.
- the invention is based on the object of making available a method for supplying a consumer from a power store and a power store which, with a high storage capacity based on volume or weight, enables extremely low-loss storage and also discontinuous power consumption.
- the method is erfindungsge ⁇ Gurss characterized in that the current load of a superconducting accumulator coil, which is constructed with superconductors very small diameter or very small layer thickness •, electrical energy pulses are supplied each with a very short period of time.
- the current storage device according to the invention is characterized in that it is designed as a superconducting storage coil with superconductors of very small diameter or very small layer thickness.
- the invention thus teaches the use of a surpal-conducting storage coil with a structure such that energy extraction is possible in the form of very short energy pulses and with extremely low eddy current losses.
- Particularly suitable, small diameters or small layer thicknesses of the Surpra conductors are less than 20 ⁇ .m, preferably less than 10 ⁇ m.
- Particularly suitable, short durations of the respective energy pulses are less than 10 ms, preferably less than 5 ms, most preferably less than 1 ms.
- a particularly preferred embodiment of the invention consists in constructing the storage coil with high-temperature superconductors.
- High-temperature superconductors are understood to be those which are superconducting even at temperatures which are considerably higher than was previously considered possible until a while ago.
- a jump temperature that is the temperature of the transition from the superconducting to the normally conducting state, 80 ° K can be given as the non-slip limit for these materials. It is typical that high-temperature superconductors are still superconducting at a temperature just below the boiling point of liquid nitrogen.
- temperature is in the range of a few degrees Kelvin, for which more concrete examples do not have to be given because they are generally known.
- the energy content per energy pulse and the large number of possible successive energy pulses mean that the energy content is high
- Typical values are more than 10 W per energy pulse, preferably 10 8 to 10 11 W.
- the small diameter or small layer thickness of the superconductor of the storage coil according to the invention means that the eddy current losses in the superconductors are kept as small as possible even when energy is drawn in the form of very short energy pulses.
- Preferred possibilities according to the invention for the production of such superconductors are vapor deposition, local mechanical removal or etching away of areas from a larger area and winding of the storage coil from very thin wires, so-called filament wires.
- the superconducting filament wires In the case of a winding structure of the storage coil, it is preferred to alternately wind the superconducting filament wires with very thin, normally conducting metal wires.
- the normally conductive metal wires should advantageously be at least as thin as the superconducting filament wires, again in order to keep the eddy current losses as small as possible even in the normally conductive metal wires.
- the term "alternating" is not only to be understood in the strict sense of the word. Rather, it should be stated that a matrix-like structure of partly superconducting and partly normal-conducting filament wires is sought, without a superconducting filament wire necessarily having to alternate exactly with a normally conducting filament wire in the axial direction and / or in the radial direction. The result of this structure is that even if the superconductivity breaks down in the superconducting filament wires, at least the normal line remains in the normally conductive metal wires.
- the storage coil is constructed with a plurality of coil segments which follow one another in the longitudinal direction of the storage coil. You can even prefabricate the individual coil segments individually and then join them together to form the storage coil. Through these measures - S-
- storage coils with smaller or larger storage capacities can be built in a particularly simple manner using the modular principle. It is also possible to manufacture the entire storage spool as a whole, for example to wind it with a continuous, superconducting filament wire on a spool core.
- the coil segments are magnetically coupled to one another, for example have a common coil core.
- electrical interconnection of the coil segments is also possible.
- a construction of the storage coil from coil segments gives the preferred possibility of interconnecting a part or all of the coil segments for loading the storage coil and / or of having different connection of the coil segments when loading and unloading the storage coil, the coil segments active during loading being identical to those during unloading active coil segments do not have to be identical.
- a particularly preferred possibility is to charge the storage coil with a connection of part or all of the coil segments in series and to discharge it in a connection of part or all of the coil segments. In this way, one has n times the discharge current of an individual coil segment when discharging with n coil segments.
- the number of coil segments directly involved in the discharge can be selected by switching modules, so that the size of the discharge current can be set in this simple manner. The The charging current is generally unchanged.
- Magnetic flux quanta can be introduced into the storage coil in particular according to the flow pump principle, that is to say distributed over time in such small "portions" that the superconducting state of the superconductors does not collapse.
- Preferred technical possibilities for this are a pulsating magnetic field, preferably generated by a rotatable magnetic ring with permanent magnets, or a pulsating field of a current conductor, which leads to the inductive introduction of magnetic flux quanta. It is possible to use the rotating mass of the magnetic ring additionally for energy storage.
- the magnetic ring is preferably driven mechanically or by an electric motor n, in particular directly driven.
- the storage coil can be loaded by a flywheel store, either in the form that the above-described magnetic ring is part of the flywheel of the flywheel store, which is preferably charged by an integrated electric motor while increasing the speed, or in the form that electric current which is generated with generator operation of the flywheel accumulator, which is fed to the storage coil.
- the donut shape leads to a particularly compact power storage and also offers particularly favorable, g 'eometrisch functional relationships for charging after Flußpumpenzin.
- the toroidal coil of the in-memory vor ⁇ 'text as used is understood to mean "in the longitudinal direction of the storage coil” so that this longitudinal direction is circular corresponding to the circular shape of the center axis of the coil.
- the ratio between the radial thickness of the superconductor-occupied space and the storage coil diameter is small.
- the diameter of the entire storage coil in the case of the torus shape measured on a cross section of the torus ring
- the radial thickness of the actual coil or the actual coil segments is as small as possible.
- the storage coil can be designed as a coreless coil or air coil.
- the storage coil is preferably formed with a core constructed with superconducting material, in particular in the form of a layer-by-layer alternation between insulating material and very thin, superconducting layers.
- the core forces the magnetic field of the coil or the coil segments to the outside and therefore leads to a magnetic field concentration.
- a device for applying a sufficiently strong one is particularly preferred .
- Magnetic field on the core which combines the superconducting state of the core. Further possibilities are introducing a sufficiently strong current pulse or an additional current pulse into the core, radiating a high-frequency field into the core, letting a laser beam act on the core and / or letting a maser beam act on the core. All in all, the field strengths and / or temperatures generated in the material of the core of the storage coil should not influence the desired superconducting state of the storage coil.
- the storage coil preferably has one or more superconducting discharge coils which are (are) magnetically coupled to the superconductors. These can be coil segments of the storage coil itself. However, it is also possible to provide separate discharge coils between the actual windings or coil segments of the storage coils. You can take advantage of a transformer effect with different number of turns.
- the technical design of the storage coil is such that at least its superconductors are arranged in a helium bath or - in the case of high-temperature superconductors - in a nitrogen ad.
- the design is usually such that this bath can dissipate the heat-producing losses from the sources in question without the superconducting state in the storage coil and / or in its core collapsing.
- Such heat sources are, in particular, the eddy currents in the superconductors which cannot be completely eliminated, the current heat losses in the metal filaments of the coil, the losses, in particular eddy current losses, in the core of the coil, the fine-flowing heat which arises in the area of the current supply and current discharge, etc. This also applies to the state that the core material has been converted into the normal conductive state.
- the laser or maser device mentioned above can be arranged in the core material and suitably shielded from the superconductors of the actual coil, so that this device does not impair the superconducting state of the coil material during its operation.
- the energy pulses extracted when the storage coil is discharged can be so short in time that the evasive movements of the flux tubes in the superconducting material of the actual coil and possibly of the core are reduced, and consequently the losses associated therewith are reduced.
- the storage coil according to the invention is very particularly suitable for supplying power to consumers who require brief current pulses of high energy.
- a typical example is high-energy workpiece processing machines.
- the storage coil according to the invention is preferably discharged with the aid of one or more superconducting high-current switches.
- This high-current switch can have superconductive material in the form of thin layers, thin wires or powder in a non-conductive matrix. It has a device with which the superconducting material can be converted from the superconducting state to the non-superconducting state and vice versa. Cooling passages are preferably present between the layers or wires or powder arrangements of the superconducting material.
- FIG. 1 is a perspective view of part of a toroidal storage coil
- FIG. 2 shows a cross section of a storage coil, for example a cross section along II-II in FIG. 1. with a superconducting coil core;
- FIG. 5 shows a storage coil in cross-section, for example along II-II in FIG. 1, for the schematic illustration of the introduction of magnetic flux quanta into the storage coil.
- the storage coil 2 shown in FIG. 1 is toroidal and has a circular toroidal cross section according to II-II.
- the supporting structure of the storage coil 2 consists of an insulator material and can be illustrated geometrically as a hollow cylinder bent in a circular shape.
- the support structure can be designed in such a way as is clearer from the embodiment according to FIG.
- Coil segments 4 are arranged in succession on the support structure along the torus ring, each of which is considered circular in itself. These coil segments are wound, for example, from very thin filament wires or are constructed with a radially successive layer sequence of insulating material and conductive material, cf. also embodiment according to FIG. 2.
- the coil segments 4 are connected to one another in an electrically conductive manner, the type of connection being explained in more detail below.
- the current conductors of the coil segments 4 consist of superconducting material, preferably high-temperature superconducting material.
- Either the entire storage coil 2 is arranged in a bath made of liquid helium or - in the case of high-temperature superconductors - made of liquid nitrogen.
- the " superconductors are cooled with smaller cooling spaces through which liquid helium or liquid nitrogen flows, as is illustrated, for example, in the embodiment according to FIG. 2.
- Connections to an outer, primary charging circuit and to an outer, secondary discharge circuit are not marked, but available.
- FIG. 2 A preferred construction of a coil segment 4 is illustrated in more detail in FIG. 2.
- the insulating support structure which has already been mentioned above, is designated by 6.
- a superconducting ring 8 thereon, for example as a vapor-deposited thin layer or a ceramic layer applied in some other way or as a remaining ring residue of a coating of superconducting material which is initially applied continuously along the storage coil 4.
- the described structure is repeated one or more times.
- the outermost coolant chamber 10 is enclosed by a housing 12.
- the superconducting rings 8 can be individually electrically connected. However, it is also possible, for example, to interrupt each superconducting ring 8 electrically at a circumferential point and, as it were, to emulate a coil with radially successive turns by corresponding electrical connection of the individual interrupted rings.
- segment-shaped carrier insulators 14 Between the two carrier insulators 14 there is a core 13, and this is very similar to the structure of the actual coil segments 4, a layer sequence of insulator layers 16, superconducting, very thin Layers 18 and flat cold rooms 20 through which liquid helium or liquid nitrogen flows.
- a coil segment 4 wound from very thin, superconducting filament wires can also be provided, possibly with more or less strictly alternatingly arranged, normally conducting, very thin metal filaments.
- 3 and 4 illustrate how the individual coil segments 4, which together form the toroidal storage coil 2, are interconnected. When charging, a series connection of the coil segments is preferred (FIG. 3), while when the storage coil 2 is being discharged, a parallel connection of the individual coil segments 4 is preferred (FIG. 4). 3 and 4, the ends of the primary circuit 22 and the secondary circuit 24 can also be seen.
- connection of the coil segments 4 it is expedient to design the connection of the coil segments 4 such that it is possible to switch from series connection to parallel connection and vice versa. It is understood that the interconnection can also be carried out in such a way that either all or only a smaller or larger part of the coil segments 4 is used directly during the discharge, for example only every second or every third coil segment 4, as a result of which the current load is longitudinal of the torus is evenly distributed.
- the torus must be cut open at one point and thought of as being rectilinear.
- FIG. 5 schematically illustrates a further preferred possibility for loading the storage coil 2.
- a superconducting plate 26 which is very " thin " in accordance with the superconductor thickness and whose plane is perpendicular to the axis of the torus ring, projects radially outward beyond the relevant coil segment 4.
- a magnetic ring 28 is concentrated rotatable to the torus ring axis 30.
- the magnetic ring has a row of permanent magnet north poles spaced circumferentially in front of the drawing plane of FIG. 5 and a row of permanently magnetic south poles distributed in the same way circumferentially behind the drawing plane of FIG. 5.
- a solenoid-shaped storage coil can be charged quite analogously, the magnet ring 28 rotating about the rectilinear solenoid axis.
- the magnet ring 28 shown can be rotated along the torus, that is to say about an axis perpendicular to the plane of the drawing in FIG. 5 through the center of the torus ring.
- the plate 26 in FIG. 5 would have to be tilted upwards by 90 °; the north poles were above and the south poles below the plateau 26.
