Investigation of Emergency Tension of Electrical Carrying Conductors of Overhead Power Line Supports
Abstract: The purpose of the paper is the development of the numerical and analytical method of problem solution of the conductor tension determination after its breakage. The solution of the problem is realized in software package MS «Excel». The model section of the overhead power line (OPL) – an anchor site. The conductor breakage is simulated in turn in each of eleven spans. The supports are considered to be the components of the whole structural system of the electrical network. The flexibility of the OPL supports has been given consideration. It was established that flexible supports get out of plumb of the remained conductor because of its tension and to the suspension point displacement after an insulator string deviation there is also the support sag. On the basis of the design and integration of the results, the relationship of the reduced tension value of the amount of the following spans of the anchor section with the remained conductor has been determined. The amount of spans necessary for finding of the maximum reduced tension value has been revealed.
Keywords: overhead power line, reduced tension, three-dimensional model, OPL support, set system of equations, design loads.
