Invention belongs to the field of energy supply, telecommunications, energy distribution networks, in particular to the grounding devices. The aim of the invention is to increase the durability of the grounded device and to improve the maintenance conditions. The grounding device consists of one or more vertical grounders. Vertical grounder is composed of steel bars (1), covered with casing of cooper or zinc, no less thicker thinner than 0.25 mm. At the ends of the bars (1) there are threads, intended for connection with the thread-connection by muffs (2) of by fingers (3) with threads. To drive the bars into the ground a steel nosepiece (4) is used, driving head (5) and electric vibro-hammer. The number of interconnected steel bars, composing the vertical grounder, their size and the number grounding points, i.e. the number of vertical grounders is decided according to the required resistance of the grounding. For the connection of the vertical grounder with the round (6) or flat (7) conductor the disassemblable connections made from the non-ferrous or regular metals of their alloys are used. The connections consists of the metal plates and have the shape of 3 dimensional geometric figures. |
