The paper presents calculation results of the electric field in a cuboidal tank provided with a system of vertical grounding rods.
The calculations made in the paper indicate that even at a relatively small space-charge density (q=100 μC/m3), the values of the field intensity and electric potential are very large and may cause a spark discharge. The presented mathematical model and the results of field calculations can be applied to the reduction of fire and explosion risks in parallelepiped tanks storing inflammable liquids.
Übersicht
Der Beitrag behandelt elektrische Felder in kubischen Behältern mit einem System von vertikalen geerdeten Stäben.
Die Berechnungen zeigen, daß selbst bei relativ kelinen Werten der Raumladungsdichte (q=100 μC/m3) die elektrische Feldstärke und das elektrische Potential sehr groß sind und einen Durchschlag verursachen können. Das dargestellte mathematische Modell und die Rechenergebnisse lassen sich als eine Methode verwenden für die Reduzierung des Feuer- und Explosionsrisikos in Behältern von der Form eines Parallelepipeds zur Speicherung leicht brennbarer Flüssigkeiten.
