Автогенерирующее дугогасительное устройство 220кВ, 40кА, СО2

Abstract

Тема выпускной работы: «Автогенерирующее дугогасительное устройство 220кВ, 40кА, СО2». В работе исследовалась отключающая способность автогенерационного дугогасительного устройства с рабочим газом СО2. Задачи, рассмотренные в ходе работы: 1). Рассмотрены высоковольтные выключатели с автогенерационным дугогасителным устройством. 2). Произведен анализ возможностей автогенерационного высоковольтного выключателя. 3). Проанализированы полученные результаты численного анализа отключающей способности ДУ с СО2 в качестве рабочего газа. В работе рассмотрены современные высоковольтные выключатели, конструкция и работа автогенерационного дугогасительного устройства, параметры рабочих газов и требования к ним. Проведён анализ взаимодействия высоковольтного выключателя с сетью. Проведен анализ динамики давления в проточной части ДУ на основании 2D-уравнений газовой динамики с учетом влиянии дуги отключения на параметры газа в камере автогенерации. Проведено исследование отключающей способности холостого хода и отключения токов короткого замыкания автогенерирующим дугогасительным устройством с СО2-изоляцией.

The topic of the graduation paper: "Arc-quenching device with heating volume220kV, 40kA, CO2". The work investigated the shut-off ability of an arc-quenching device with chamber with heating volume with a working CO2 gas. Tasks considered during the work: 1). High-voltage circuit-breaker with an arc-quenching device with chamber with heating volume are considered. 2). Analysis of the possibilities of a device with chamber with heating volume high-voltage circuit-breaker is carried out. 3). Obtained results of the model with CO2 as the working gas are analyzed. The paper considers modern high-voltage circuit-breaker, the design and operation of an arc-quenching device with chamber with heating volume, the parameters of working gases. The analysis of the interaction of a high-voltage circuit-breaker with the network is carried out. A study of the shut-off capability of idling and disconnecting short-circuit currents has been carried out.
