Vliv znečištění a vlhkosti na izolátorových závěsech u vedení přenosové soustavy na velikost svodových ztrát

Abstract

This thesis examinates the influence of pollution and humidity on transmission network insulator strings on value of leakage losses. The transmission, theory electrical network and analysis of the technical losses of the electrical energy on the high-voltage line and very high-voltage line are described at the begin of the thesis. Methodology of calculation is be grounded about new parameters such as form factor, composition of insulator string, specific surface conductivity, pollution, etc. Methodology for calculating leakage losses at new re insulated line of transmission system are used for calculate. Calculations of leakage losses at the occasion of three-model line for comparison results leakage looses at used insulation strings are executed. An assessment of results and propose options for practical use are summarize in the end of thesis.
