Description

Um festzustellen, ob Spannung auf der Elektrozaunanlage ist, wird seit langem ein Spannungsprüfer verwandt, bei dem eine Glimmröhre und ein Widerstand in Reihe geschaltet sind. Wird dieser Spannungsprüfer an den Elektrozaun gehalten, so fließt ein Strom vom Elektrozaun über die Prüfspitze durch den Widerstand in die Glimmröhre und durch den menschlichen Körper in die Erde. Diese Spannungsprüfer haben jedoch den Nachteil, daß sie auch Spannungen durch Aufleuchten der Glimmröhre anzeigern, die infolge schlechter Isolation des Zaundrahtes bei weitem nicht mehr ausreichen, die Tiere abzuschrecken und von dem Draht fernzuhalten. Die bei verschieden hohen Spannungen unterschiedliche Helligkeit der Glimmröhre ist nur gering und im Freien unter wechselnden Lichtverhältnissen in keinem Fall zu unterscheiden und deshalb als Maß für die Höhe der Spannung unbrauchbar. Die prüfende Person wird also getäuscht und merkt erst an dem Verhalten der Tiere, daß die Spannung infolge irgendeines Fehlers zu niedrig ist. To determine whether there is voltage on the electric fence system A voltage tester has been used for a long time, in which a glow tube and a resistor are connected in series. If this voltage tester is held on the electric fence, a current flows from the electric fence over the test probe through the resistor in the glow tube and through the human body into the earth. These voltage testers however, they have the disadvantage that they also generate voltages due to the glow tube lighting up show that, due to poor insulation of the fence wire, they are nowhere near any more sufficient to deter the animals and keep them away from the wire. The at different high voltages different brightness of the glow tube is only slight and im In no case can be distinguished from outdoors under changing light conditions and therefore useless as a measure of the level of tension. The examiner will So he was deceived and only noticed from the behavior of the animals that the tension was the result some error is too low.

Der Erfindungsgegenstand stellt einen Spannungsprüfer dar, bei dem erflndungsgemäß mit einer Glimmröhre I und einem Widerstand 2 eine Funkenstrecke 3 in Reihe geschaltet ist. Ist die Spannung hoch genug, so wird die Funkenstrecke 3 (s. Abbildung) durchschlagen und es fließt ein Strom über den Widerstand 2 durch die Glimmröhre I, die dann aufleuchtet. Im Falle einer schlechten Isolation des Zaundrahtes ist die Spannung zu niedrig, um die Funkenstrecke 3 zu durchschlagen, und die Glimmröhre I Ieuchtet nicht auf. The subject of the invention is a voltage tester in which according to the invention with a glow tube I and a resistor 2 a spark gap 3 is connected in series. If the voltage is high enough, the spark gap becomes 3 (see illustration) break down and a current flows through resistor 2 the glow tube I, which then lights up. In case of bad insulation of the Fence wire, the voltage is too low to break through the spark gap 3, and the glow tube I does not light up.

Mit diesem Spannungsprüfer ist der prüfenden Person ein sicheres, nicht täuschendes Hilfsmittel gegeben, das nicht nur wie bisher anzeigt, ob Spannung vorhanden ist oder nicht, sondern ob die vorhandene Spannung hoch genug ist, das Fell der Tiere zu durchschlagen und die Tiere so vom Zaun abzuschrecken. With this voltage tester, the testing person has a safe, A non-deceptive aid is given that not only shows, as before, whether there is tension is present or not, but whether the voltage present is high enough that the To break through the fur of the animals and thus scare them off the fence.
