Description
Der Erfindung liegt der Gedanke zugrunde, einen Spannungs indikator als stangenförmiges Gerät auszubi1den, das namentlich für den Land- und Überlandgebrauch besonders geeignet ist, Zu diesem. The invention is based on the idea of a voltage indicator designed as a rod-shaped device, specifically for land and overland use is particularly suitable to this.
Zweck besitzt der Indikator gemäß der Erfind-ung die Gestalt eines Spazierstockes, an dessen Oberende die Signallampe angebracht ist, wie die Zeichnung an Hand eines Ansfüh.rungsbeispiels erkennen läßt.Purpose of the indicator according to the invention has the shape of a Walking stick, at the top of which the signal lamp is attached, like the drawing can be recognized on the basis of an example.
Der im allgemeinen aus Holz bestehende Stock I ist in an sich bekannter Weise mit einer Metallzwinge 2 versehen, die mittels eines zweckmäßiger-Weise Idrahtförmigen und gegebenenfalls isolierten I eiters3 mit dem Pol4 der Fassung 5 einerLampe6 in leitender Verbindung steht. Der andere Pol oder Kontaktteil .dSer Fassung 5 ist als metallisches Schutzgehäuse 7 für die Lampe 6 ausgebildet und an dem Stock 1 z. B. durch (nicht dargestellte) Schrauben befestigt. The stick I, which generally consists of wood, is known per se Way provided with a metal clamp 2, which by means of an expedient I wire-shaped and optionally insulated conductor3 with the pole4 of the socket 5 of a lamp6 in conductive connection. The other pole or contact part .dSer version 5 is designed as a metallic protective housing 7 for the lamp 6 and attached to the stick 1 z. B. fixed by screws (not shown).
Wird nun die Zwinge 2 auf den Erdboden aufgesetzt oder in diesen gestoßen und das Gehäuse 7 mit Ider zu prüfenden Leitung od. dgl in Berührung gebracht, so erfolgt bei Vorhandensein einer Spannung über die Lampe 6 eine Ableitung zur Erde, so daß die Lampe aufleuchtet. If now the clamp 2 is placed on the ground or in this pushed and the housing 7 brought into contact with the line to be tested or the like, when a voltage is present across the lamp 6, a derivation for Earth so that the lamp lights up.
Ist die Länge des. Stockes wesentlich größer als der Rodenabstan,d des spannungführenden Leiters und läßt sich diese Längeiidifferenz nicht durch entsprechend tiefes Einbohren des Stockes in den Erdboden ausgleichen, so kann man den Stock schräg stellen bzw. schräg in den Boden stoßen. Is the length of the stick much greater than the distance between the digging trees, d of the live conductor and this difference in length cannot be passed through accordingly To compensate for deep boring of the stick into the ground, you can use the stick place at an angle or push into the ground at an angle.
Bei Verwendung einer Glimmlampe mit minimalem Stromdurchgang als Indikator ist es gelegentlich auch möglich, die Lampe allein dadurch zum Aufleuchten zu bringen, daß man entweder nur die Zwinge 2- oder nur das Gehäuse 7 mit dem zu prüfenden Leiter in Berührung bringt, sofern dieser eine entsprechend hohe Spannung führt. Die Ableitung zur Erde erfolgt dann durch den Stock über den menschlichen Körper. Gegebenenfalls kann hierbei ein hoher 'Schutzwiderstand vorgesehen sein, der den den Körper durchsetzenden Strom auf eine in jedem Fall ungeflihrliche Stärke begrenzt. When using a glow lamp with minimal current passage as Indicator it is occasionally also possible to light up the lamp by this alone to bring that one either only the clamp 2- or only the housing 7 with the too the conductor to be tested, provided that it has a correspondingly high voltage leads. The derivation to earth then takes place through the stick via the human Body. If necessary, a high 'protective resistance can be provided here, the current passing through the body to an in any case harmless strength limited.
