110KV变电站设计设计说明VIP专享

摘 要电力工业是国民经济的重要部门之一，它是负责把自然界提供的能源转换为供人们直接使用的电能的产业。它即为现代工业、现代农业、现代科学技术和现代国防提供不可少的动力，又和广阔人民群众的日常生活有着密切的关系。电力是工业的先行。电力工业的进展必须优先于其他的工业部门，整个国民经济才能不断前进。本次设计任务为 110KV 变电站电气一次初步设计。其容包括设计原始资料，主变的选择，电气主接线的选择，短路电流的计算，电气设备的选择，配电装置的结构型式，站用电源的选择，防雷保护，接地装置的说明，无功补偿。关键词：变电站；负荷；主变；主接线；短路电流AbstractThe power industry is an important sector of the national economy, which is responsible for the energy provided by nature for people to be directly converted into electrical energy used in the industry. It is the modern industry, modern agriculture, modern science and technology and to provide essential modern defense force, again, and the daily lives of the masses is closely related. Electricity is the industry's first. Development of power industry must take precedence over other industrial sectors, the entire national economy can continue to move forward.This design task for 110KV substation electrical a preliminary design. Its content includes the original design data, the main choice of change, the main electrical wiring, short-circuit current calculation, electrical equipment choice, structure of power distribution device, station selection of power supply, lightning protection, grounding device, no power compensation.Keywords: substation; load; transformer; main connection; short circuit current目 录第一章原始资料 41.1 环境条件 41.2 电力系统情况 4第二章主变压器的选择 6第二章主变压器的选择 62.1 负荷分析 62.2 主变台数的确定 72.3 主变容量的确定 72.4 主变相数选择 72.5 主变绕组数选择 72.6 主变绕组连接方式 82.7 所用变选择 9第三章电气主接线的选择 103.1 电气主接线...
