Вдосконалення методів і засобів захисту від впливу електричного поля на обслуговуючий персонал електричних мереж напругою 220-750 кВ

Abstract

In the thesis the conditions of safe performance of repair works under voltage at 220-450 kV transmission lines were investigated. The means of protection of the person from the influence of the electromagnetic field and shielding devices, used in work in the electrical installations of ultrahigh voltage, are analyzed. The calculation of screening properties of portals and supports of electrical installations of 220-750 kV is carried out. The calculation of the electric field in the areas of cable rope gap is calculated. Also, in the economic part of the thesis, for the 330 kV line of Vinnytsia-West Ukrainian PuAT Vinnytsyaoblenergo, the techno-economic effect from the implementation of repair work under stress is calculated.
