35kv降压变电站设计和实现 电气化专业

摘 要电力行业是发电、输送电和分配电能的工业部门。曾都洛阳镇旅游业的发展张畈供区负荷不断增长，本次设计主要对本地区新建 35KV 的变电站进行设计。根据本地区供电需求。电力负荷峰谷差越来越大，低电压问题突出，影响该地区的优质可靠供电。目前虽有 35kV 洛阳变 10kV 洛 55 张畈线，但由于供电半径大，线损高、电压合格率低，故供区内用户电压质量得不到保证。着重解决了配电装置的选择、防雷保护与接地保护的配置，并结合本地区的供电需求和工程实际情况选择出最合适的方案,各种电气的设备型号以及容量。关键字：35KV；变电站；母线；配电装置；避雷针ABSTRACTThe power industry is the industrial sector that generates electricity, delivers electricity and distributes electricity. Entire power system safe, reliable, economical operation. The graduation design mainly for the region to build 35KV substation design. According to the demand of power supply in the region, the load statistics, the selection of the main wiring scheme of the substation, the selection of the number and capacity of the main transformer, the selection of the short circuit and the selection of the switching equipment, the selection of the power distribution device, the lightning protection and the grounding device Design, relay protection options. Combined with the region's power supply needs and the actual situation of the project to choose the most appropriate program, a variety of electrical equipment model and capacity.Keywords:35KV；Substation；bus line；power distribution unit；lightning rod1目 录摘要…………………………………………1Abstract.……………………………………2第一章 引言…………………………………5 1.1 原始资料……………………………………5第二章：电气主接线…………………………6 2.1 电气主接线设计简介………………………6 2.2 电气主接线特点……………………………6 2.3 电气主接线选择……………………………7第三章：变压器的选择…………………………8 3.1 主变压器台数的确认……...
