Проектирование защиты трансформатора ÑÐ¾Ð±ÑÑ‚Ð²ÐµÐ½Ð½Ñ‹Ñ Ð½ÑƒÐ¶Ð´ станции

Abstract

Основное содержание данной работы заключается в разработке защиты трансформатора в соответствии с потребностями самой электростанции. Задачи, которые решались в ходе проектирования: 1) Проектирование электрической части электростанции: подбор силового оборудования (генераторов, трансформаторов), схем распределительных шкафов и основных схем электрических соединений ТЭЦ; 2) Рассчитайте ток короткого замыкания и настройки защиты трансформатора.; 3) Завершите выбор электрооборудования, такого как автоматические выключатели, генераторные выключатели, трансформаторы тока, трансформаторы напряжения, провода и шины. В ходе проектирования рассчитаны токи трехфазного короткого замыкания, по которым произведен дальнейший выбор оборудования и токоведущих частей для КРУЭ 220 кВ и РУ СН 6 кВ. Применены параметры разъединителя ELK - 220 / 3150 УХЛІ, КРУЭ СПЭ - 1000,Технические характеристики ЭГРУ НЕС 7.

The main content of this work is to develop transformer protection in accordance with the needs of the power plant itself. Problems that were solved during the design: 1) Design of the electrical part of the power plant: selection of power equipment (generators, transformers), distribution cabinet diagrams and basic electrical connection diagrams of the thermal power plant; 2) Calculate the short circuit current and protection settings of the transformer.; 3 )Complete the selection of electrical equipment such as circuit breakers, generator breakers, current transformers, voltage transformers, wires and busbars. During the design, three-phase short circuit currents were calculated, based on which further selection of equipment and current-carrying parts was made for 220 kV switchgear and 6 kV SN switchgear. The parameters of the disconnector ELK - 220 / 3150 UHLI, GIS SPE - 1000, technical characteristics of EGRU NES 7 were used.
