Оптимизация нелинейного ограничителя перенапряжений 750 кВ

Abstract

Рассмотрена и проанализирована типовая конструкция нелинейного ограничителя перенапряжений. Произведен выбор диаметра варисторов и высоты колонки варисторов по пропускной способности и рабочему напряжению. Исследована механическая устойчивость несущей стеклопластиковой конструкции ОПН. Подобрана система выравнивающих распределение напряжения вдоль колонки ОПН металлических экранов, с учетом которых произведен выбор изолятора. Проанализирован нагрев оксидоцинковой керамики в результате протекания через нее большого тока.

A typical construction of surge arrester is analysed in this work. The diameter of varistor and the height of varistor column were calculated by means of maximal current and voltage. Mechanical stability of GRP pipes is studied. The screen and insulation systems are calculated. Thermal calculation of varistors is done.
