Расчет сил сжатия дистанционных распорок расщепленных фаз при коротком замыкании‌‌‌

Расчет сил сжатия дистанционных распорок расщепленных фаз при коротком замыкании‌‌‌

Abstract

The paper presents an approximate method for calculation of electrodynamic resistance parameters of a flexible bus-bar with bundled phases. Comparison of the approximate calculation results with the computer calculations using a FAZA software tool has been given in the paper. An evaluation of permissible aerial cable spacer compression forces for designed modern standard distribution substations of 330 and 550 kV has been provided in the paper. The paper proposes an algorithm for determination of dynamics parameters in a bundled phase with due account of influence pertaining to viscoelastic characteristics of damping spacers.

Излагается приближенный метод расчета параметров электродинамической стойкости гибкой ошиновки с расщепленными фазами. Приводится сопоставление результатов приближенного расчета с компьютерными расчетами по программе FAZA. Дается оценка допустимых сил сжатия распорок проектируемых современных типовых распределительных устройств 330 и 500 кВ. Предлагается алгоритм определения параметров динамики расщепленной фазы с учетом влияния упруго-вязких характеристик демпфирующих распорок.
