Description

Vorrichtung zum Prüfen der elektrischen Festigkeit, insbesondere flüssiger Materialien. Der Gegenstand der Erfindung sei an Hand des beiliegenden Lichtbildes näher erläutert.Device for testing electrical strength, especially liquid Materials. The subject of the invention is based on the accompanying photograph explained in more detail.

z ist die Vorrichtung zur Prüfung des Materials gemäß dem Hauptpatent: 2 ist ein Voltmeter für hohe Spannungen, beispielsweise von tooo bis 8ooo Volt: 3 ist ein Teil eines Gehäuses, in dem ein Stufentransformator li..egt. -. sind Stö pselleitungen zur Einstellung verschiedener Stufen des Transformators (zweckmäßig niederspannungsseitig). 5 ist ein Vorschaltwiderstand zur Regelung der Stromstärke niederspannungsseitig oder auch der Spannung. 6 ist ein gewöhnlicher Drehschalter, mit dem die Niederspannung ein- und ausgeschaltet werden kann, welche dem Ortsnetz entnommen werden kann. 7 ist eine mit Glas verschlossene Tür, nach deren Öffnen es möglich ist, den Prüfapparat herauszunehmen und das zu prüfende Material einzufüllen bzw. ein7uschieben (0l, Papier, Kautschuk usw.) oder herauszunehmen. Bei geöffneter Tür ist durch entsprechende, von der Tür gesteuerte oder mit dieser verbundene Kontakte die Stromzuführung (Niederspannung) unterbrochen (Türblockierungen). 8 ist die stöpselbare Zuführung der Hochspannung an eine Klemme am Isolator des Prüfapparates. 9 ist die andere Stromzuführung der Hochspannung; 1o ist eine Vorrichtung, welche verschiedene Meßbereiche des Voltmeters 2 einzuschalten gestattet, vorzugsweise eine Kondensatoreinrichtung. Das @"oltmetrr 2 ist nach elektrostatischem Prinzip gebaut mit einem Biskuit zwischen Metallplatten und einem Bremsmagneten (Stahlmagneten). I I ist ein Schlauch, durch den das Wasser abfließen kann, welches den unteren Teil des Apparates durchstörmt. Der Schlauch mündet in einen Trichter innerhalb des Kastens 12, über den ein Auslaßhahn des Prüfapparates zum Prüfen kommt. Die zweckmäßig schlauchartige Zuführung des Wassers ist nicht gezeichnet. Das Wasser dient zur Konstanthaltung einer bestimmten Temperatur oder zur Kühlung.z is the device for testing the material according to the main patent: 2 is a voltmeter for high voltages, for example from tooo to 8ooo volts: 3 is part of a housing in which a step transformer is located. -. are disturbances pselleeleitungen for setting different stages of the transformer (expedient low voltage side). 5 is a series resistor for regulating the current intensity on the low-voltage side or the voltage. 6 is an ordinary rotary switch, with which the low voltage can be switched on and off, which the local network can be taken. 7 is a door locked with glass, after opening it it is possible to take out the testing apparatus and fill in the material to be tested or insert (oil, paper, rubber, etc.) or remove it. When open The door is through corresponding contacts controlled by the door or connected to it the power supply (low voltage) interrupted (door blocking). 8 is the pluggable one The high voltage is fed to a terminal on the insulator of the test apparatus. 9 is the other high voltage power supply; 1o is a device which various Allowing measuring ranges of the voltmeter 2 to be switched on, preferably a capacitor device. The @ "oltmetrr 2 is built according to the electrostatic principle with a biscuit between Metal plates and a brake magnet (steel magnet). I I is a hose, through the water that flows through the lower part of the apparatus can drain away. The hose opens into a funnel within the box 12 through which an outlet tap of the test apparatus comes to test. The expedient hose-like supply of the Water is not drawn. The water is used to keep a certain constant Temperature or for cooling.

Der Vorteil der Erfindung besteht darin, daß ein kompletter Apparat hochspannungssicher, einfach bedienbar und auf geringsten Raum zusammengedrängt geschaffen ist.The advantage of the invention is that a complete apparatus High voltage safe, easy to use and packed into the smallest space is created.
