摘要
文章介绍了220kV和110kV变电站典型设计的目的、输入条件和主要技术经济指标,并按照配电装置的形式确定了户外变电站、户内变电站和半地下变电站3类典型设计基本方案;重点分析了220kV和110kV变电站典型设计的主要技术方案和各个模块的技术特点,对各级电压的电气主接线形式、短路电流水平等进行了详细的说明;通过费用概算及实际应用表明,典型设计具有节省投资、节约占地、提高供电可靠性、增加规划的灵活性等特点。
The purpose, input conditions and main technical and economical indices of typical design for 220kV and 110kV substations are presented, according to the form of the power distribution unit the typical design is divided into three basic schemes for outdoor, indoor and semi-subterranean substation respectively. The main technical schemes of typical design for 220 kV and 110 kV substations and technical features of these modules are emphatically analyzed; the main wiring forms for various voltage grades, short circuit current level and so on are illustrated in details. The cost estimate and practical application show that typical design possesses such features as saving investment, reducing the land occupation, improving power supply reliability and enhancing the flexibility of planning.
