Секционный разъединитель для ЗРУ 20 кВ, 630 А

Abstract

В работе представлен принцип разработки конструкции секционного разъединителя 20 кВ, 630 А. Рассмотрены возможные исполнения разъединителей в закрытых распределительных устройствах. Произведен выбор межполюсных расстояний, расстояний между контактами одного полюса в отключенном состоянии и выбор опорных и тяговых изоляторов. Выполнен расчет электродинамических усилий: конструкция проверена на механическую прочность. Произведен тепловой расчет, доказывающий отсутствие перегрева токоведущих частей.

The principle of design sectional disconnectors 20 kV, 630 A is presented in paperwork. Disconnectors possible fulfillments in enclosed switchgear are considered. Interpole distances, distances between the contacts of one pole in a disconnected state and the support and draft insulators are selected. Design tested for mechanical strength. Thermal calculation, proving the absence of overheating of live parts is produced.
