Description

Überspannungsschutzeinrichtung mit vollständig geschlossenem Gehäuse Für den Schutz von Niederspannungsanlagen gegen hohe Überspannungen sind Anordnungen erwünscht, die jederzeit im Freien angebracht werden können und die außer einer Überschlagstelle noch einen Widerstand enthalten, um eine Abführung des nachfließenden Betriebsstromes möglichst zu verhindern. Eine besonders einfache Ausführung dieser Art wird gemäß der Neuerung dadurch erreicht, daß die Zuführung durch eine als Regenschutz dienende Haube aus Isoliermaterial erfolgt, die auf ihrer Innenseite mit einem entsprechenden Metallbelag versehen ist. Diesem Metallbelag steht ein Widerstandsstab gegenüber, dessen untere geerdete Fassung durch entsprechende Seitenwände mit der Isolationskappe zu einem Gehäuse vereinigt ist, wobei von letzterem der Anschluß zur Erde geht. Es läßt sich dann bei entsprechender Einstellung des Kopfes des Widerstandsstabes, der, falls er aus Kohle oder anderen Stoffen besteht, in geeigneter Weise metallisiert ist, eine der Spannung entsprechende Widerstandsausführung herstellen. Will man dazu übergehen, diese Anordnung für verschiedene Spannungen einstellen zu können, so kann man den Widerstandsstab durch eine entsprechende Hebe- und Senkvorrichtung dem Metallbelag des Haubenisolators mehr oder weniger nähern; man kann sogar außen,an der Fassung des Widerstandes eine Skala anbringen, an der man von außen erkennen kann, für welche Spannung die betreffende Schutzeinrichtung eingestellt ist.Surge protection device with completely closed housing There are arrangements for the protection of low-voltage systems against high overvoltages desired, which can be installed outdoors at any time and which except one The flashover point still contains a resistance in order to dissipate the inflowing To prevent operating current as much as possible. A particularly simple implementation of this Art is achieved according to the innovation in that the supply through a rain protection serving hood is made of insulating material, which is on its inside with a corresponding Metal covering is provided. Opposite this metal covering is a resistance rod, its lower grounded socket through corresponding side walls with the insulation cap is combined into a housing, the connection of the latter going to earth. With the appropriate adjustment of the head of the resistance rod, it can then be which, if it consists of coal or other materials, metallizes in a suitable manner make a resistor version that corresponds to the voltage. Do you want move on to being able to adjust this arrangement for different voltages, so you can raise and lower the resistance rod with an appropriate lifting and lowering device more or less approach the metal coating of the hood insulator; you can even look outside attach a scale to the socket of the resistor, which can be recognized from the outside can determine the voltage for which the protective device is set.

In den Abbildungen ist eine der möglichen Ausführungsformen dargestellt. Die als Regenschutz ausgebildete, aus Isoliermaterial bestehende Haube a besitzt auf ihrer Innenseite einen Metallbelag b, der direkt über die Leitung c mit der Niederspannungsleitung verbunden ist. Die Haube a wird von dem Gehäuseteil d getragen, der aus Metall besteht und bei e geerdet ist, In dem Gehäuse befindet sich der aus Kohle bestehende Widerstandsstab f, dessen Kopf g metallisiert ist. Der Abstand dieses Kopfes g von dem Metallbelag b kann durch das Gewinde h geändert werden.One of the possible embodiments is shown in the figures. The hood formed as a rain cover and made of insulating material has a on its inside a metal coating b, which is directly over the line c with the Low voltage line is connected. The hood a is carried by the housing part d, which is made of metal and is earthed at e. The from is located in the housing Coal existing resistance rod f, the head g of which is metallized. The distance this head g of the metal covering b can be changed by the thread h.
