Chernyuk A. The characterization of electro physical parameters of electrical grounding devices of mobile electric lines in the sandy soils

Research object: process of the electrolytic grounding of movable electricobject. Purpose: development of method of determination of resistance of the electrolytic grounding on the basis of analysis of process of the electrolytic grounding in heterogeneous sandy soils, possessing percolatin and fractal properties. Research methods: analysis of percolatin model of process of formation of channels of conductivity; use: vehicle of fractal geometry for determination of properties of electrolytic cluster within the framework of by volume body of electrolyte in soil, theory of conductivity of electrolytes at development of method of calculation of resistance of the electrolytic grounding, classic methods of measuring of resistance of earthings devices and methods of physical design for experimental determination of electricphysical parameters of superficial electrolytic grounding. Theoretical and practical results: the method of calculation of resistance of the electrolytic grounding, taking into account the volume of the utillized electrolyte, is developed, developed and tested pre-production model superficial electrolytic grounding of the improved construction. Scientific novelty: the physical model of process of the electrolytic grounding is developed, which represents and takes into account the phase changes of sandy soil and his percolatin-fractal properties structurally, new analytical expressions are got for determination of electricphysical parameters of the electrolytic grounding. Introduction: results are inculcated in AK "Khar'kovoblenergo" (Kharkov), LTD "Energetic" (Kharkov), LTD "Megapolis+" (Kharkov). Sphere of the use: planning and exploitation of the systems of the protective grounding of movable electricobject is in sandy soils.
