Description

Anordnung zur Bestimmung der Richtung eines in der Erde fließenden Wechsel- oder Gleichstromes. Die Richtung eines in der, Erde fließenden Wechselstromes wurde bisher mit der von R. C o u r a n t angegebenen Anordnung bestimmt. Dabei werden vier Elektroden etwa als Eckpunkte eines Quadrates in die Erde versenkt und vier Spulen in gleicher Anordnung aufgestellt. Anfang und Ende jeder Spule sind mit je zwei Elektroden verbunden. Jede Spule wird demnach von einer aus der Erde abgezweigten Stromkomponente durchlaufen. Die Windungsebene jeder Spule sei dabei parallel der Verbindungslinie der beiden Elektroden, mit denen sie verbunden ist. Die Stärke der abgezweigten Stromkomponente hängt ab von dem Erdwiderstand zwischen den beiden Elektroden. In der Mitte der vier Spulen steht eine Induktionsspule; die um eine Achse drehbar ist, die senkrecht zur Ebene der Spulenachse steht. Die Enden der Induktionsspule stehen in Verbindung etwa mit einem Telephon. Dreht man die Spule, so läßt sie sich auf ein Maximum oder Minimum des Telephontones einstellen. Die Maximum- oder Minimumstellung gibt dann die Richtung des. Wechselstromes in der Erde..Arrangement for determining the direction of a flowing in the earth Alternating or direct current. The direction of an alternating current flowing in the earth was previously determined with the arrangement given by R. C o u r a n t. Included four electrodes are sunk into the earth as corner points of a square and four coils placed in the same arrangement. The beginning and the end of each reel are connected to two electrodes each. Each coil is made from one of the earth run through branched current component. The winding level of each coil is included parallel to the line connecting the two electrodes to which it is connected. The strength of the branched-off current component depends on the earth resistance between the two electrodes. In the middle of the four coils is an induction coil; which is rotatable about an axis which is perpendicular to the plane of the coil axis. the Ends of the induction coil are in communication with a telephone, for example. One turns the coil, it can be adjusted to a maximum or minimum of the telephone tone. The maximum or minimum position then indicates the direction of the alternating current in the earth..

Die Erfindung vereinfacht diese Anordnung, indem sie nur drei Elektroden und drei Spulen verwendet. Elektroden und Spulen können zweckmäßigerweise in der Form eines gleichseitigen Dreiecks angeordnet werden, wie es in der Abbildung dargestellt ist. Von den drei Tastelektroden p1, p2, P3 sind je zwei mit den Enden der drei Spulen s., 2, Si, 3, s2, s verbunden. Die drehbar angeordnete Induktionsspule d steht wieder etwa mit einem Telephon in Verbindung, und durch das Tonminimum oder -maximurn ist dann die Stromrichtung in dem Feld zwischen den drei Tastelektroden bestimmt, und da die Äquipotentiallinien im allgemeinen auf der Stromrichtung senkrecht stehen, so ist auch deren Richtung bekannt. Die ganze Anordnung dient also ebensowohl zur Aufsuchung der Xquipotentia'linien wie der Stromlinien.The invention simplifies this arrangement by only having three electrodes and three coils used. Electrodes and coils can expediently in the Can be arranged in the shape of an equilateral triangle as shown in the picture is. Of the three touch electrodes p1, p2, P3, two are each with the ends of the three Coils s., 2, Si, 3, s2, s connected. The rotatably arranged induction coil d stands again connected to a telephone, for example, and through that The pitch minimum or maximum is then the direction of the current in the field between the three Sensing electrodes are determined, and since the equipotential lines are generally on the direction of the current are perpendicular, their direction is also known. The whole arrangement serves thus just as much for the search for the Xquipotentia 'lines as for the streamlines.

Die gleiche Anordnung kann auch verwendet «-erden zur Bestimmung der Richtung eines im Boden fließenden Gleichstromes, wenn statt der drehbaren Spulen eine Magnetnadel benutzt wird, die in einer Aufhängung drehbar ist. Hierbei gibt dann die Richtung der Magnetnadel, z. B. die Lage ihres @Tordpoles, die Richtung des Gleichstromes in der Erde an.The same arrangement can also be used to determine the Direction of a direct current flowing in the ground, if instead of the rotating coils a magnetic needle is used, which is rotatable in a suspension. Here there then the direction of the magnetic needle, e.g. B. the location of your @Tordpoles, the direction of the direct current in the earth.

Die Wirkung jeder Spule muß stets dem Abstand zwischen den entsprechenden Tastelektroden proportional sein. Außerdem kann die Spulenwirkung durch Eisenkerne erhöht werden. Statt drei Spulen zu verwenden, kann man sich auch mit zwei Spulen begnügen, die miteinander denselben Winkel bilden, wie die Verbindungslinien zweier Tastelektroden.The action of each coil must always correspond to the distance between the corresponding Tactile electrodes be proportional. In addition, the coil effect can be achieved by iron cores increase. Instead of using three coils, you can also use two coils be satisfied that they form the same angle with each other as the lines connecting two Tactile electrodes.
