Abstract

The earthing terminal comprises two concentric tubes (1,2), with the inner tube (2) passing through the top end plate (3) of the outer tube (1). The inner tube is fitted to the bottom end plate (7) of the latter. The inner tube (2) is of metal, while the outer tube (1) is made of metal, plastics or an insulating material. The space between the tubes (1,2) is filled over the bottom two thirds of their height with a mixture (6) of oil and carbon powder, with a plate (5) separating it from the remaining third which is filled with oil (4). This separation plate (5) has a central aperture for locating the inner tube (2) and smaller surrounding apertures (9) allowing infiltration of the oil (4) into the mixture (6). The earthing terminal exhibits a low resistance.

Description

La présente invention, concerne un assemblage ; de deux tubes, l'un
Extérieur,l'autre intérieur ; relié au centre de la plaque inférieure
Et solidaire de cette plaque,qui obstrue;la partie inférieure du tube Ext érieur; entre ces deux tubes se placent,de la poussière de charbon
Mélangée, à de l'huile ;sur les un tiers de la hauteur du tube,et sépares
De l'autredeuxtriers du tube,par une entretoise;qui est perce de trous
Ce qui pernet,à l'huile contenue dans ces un tiers,de la partie
Supérieure;de s'écouler, dans la partie inférieure;et d'alimenter
De ce fait la poussiere,ou grenaille de charbon en huile;afin que cette
Partie dans laquelle plonge le tube central qui sert de conducteur
Avec la partie extérieure ,soit irrigué en permanence.The present invention relates to an assembly; of two tubes, one
Outside, the other inside; connected to the center of the bottom plate
And secured to this plate, which obstructs the lower part of the outer tube; between these two tubes are placed, coal dust
Mixed with oil; over a third of the height of the tube, and separated
From the other two sorters of the tube, by a spacer; which is drilled with holes
What pernet, to the oil contained in these thirds, of the part
Upper; to flow, in the lower part; and to feed
Thereby the dust, or shot of coal in oil; so that this
Part in which plunges the central tube which serves as a conductor
With the outside, be permanently irrigated.

In which the device is placed, the part 12 being the fill, which
Fill the hole, and isolate the device externally from the walls of the hole
This principle, by joining the lower part of the central tube, with the
