摘要 变电所高压开关设备电气设计 摘要 本文对变电所高压开关设备相关的电气知识和变电所电气设计作一些介绍。第一章主要介绍电力系统方面的知识,包括电力系统一次接线、接地系统、新能源以及高压开关柜五个方面。其中对电力系统一次接线的特点和使用场合作了详细介绍。同时对于新能源的发展现状,国内外对比,以及装机容量,技术进步也有一定描述。高压开关柜方面内容是本次毕业设计的主要部分,不仅从国内外高压开关柜的发展,以及技术进步(小型化/智能化)作了分析,同时对现在常用的高压开关柜的种类型号,产品技术参数,特性等也有较为详细的介绍。第二章以介绍电器元件为主,包括变压器,断路器、电流互感器、电压互感器、微机保护装置以及开关状态值指示仪等。并对产品的种类型号,技术参数,产品特性作了详尽的描述。对于何种场合应该选择何种类型的电器元件有参考作用。 最后一章是电气工程设计一方面给出了完整的电气设计图纸,包括一次图、二次图、端子图和设备材料表,另一方面给出了一次回路和二次回路原理分析。关键词:电力系统 高压开关柜 断路器 电气设计Abstract Electrical design of substation high - voltage switchgearAbstract This article on the substation of high voltage switchgear related to the electrical knowledge and substation electrical design for some introduction. The first chapter introduces the power system knowledge, including the power system a wiring, grounding system, new energy and high voltage switchgear five aspects. Which the characteristics of a power system wiring and the use of a detailed description of the occasion. At the same time for the development of new energy status, domestic and international comparison, as well as installed capacity, technological progress also have a certain description. High-voltage switchgear aspects of the graduation design is the main part of this, not only from the development of high-voltage switchgear at home and abroad, as well as technological progress (miniaturization / intelligent) made an analysis, while the commonly us...
