加速器产业园配电工程系统设计 摘要 随着国家经济的不断发展， 电力行业也迅速发展， 社会对电力行业的要求也 越来越严苛，特别在供电质量方面，要求电力输出稳定、可靠和持续。为了达到 电力供电质量的提升， 就需要对变电所进行经济合理的设计， 对电气设备的配置 达到规定的要求。对于新建的变电所来说， 一般要求变电设备能够运行稳定可靠、 在操作方面能够做到灵活、 投资经济合理， 而且考虑后期的发展， 预留扩建升级 的空间。本设计主要对加速器产业园进行 35KV的降压变电所设计，该变电所设 计考虑的电压等级为 35KV 和 6KV。按照变电所设计的一般步骤，首先考虑该区 的负荷等级以及计算， 对该变电站进行无功补偿计算和选型， 确定变电所的形式 并完成变压器的型号确定， 重点进行电气主接线的比较和选择， 对短路电流进行 计算并且完成设备的选型等。 系统设计考虑选择两台主变压器， 在此基础上进行 断路器、隔离开关、电流互感器、电压互感器等的选型和校验，是系统运行安全 可靠、操作简单方便、设计经济合理。 关键词 ：变电所；负荷计算；短路电流；设备选型 Abstract With the continuous development of the national economy and the rapid development of the power industry, the requirements of the society for the power industry are becoming more and more stringent. Especially in the aspect of power supply quality, the power output is required to be stable, reliable and sustainable. In order to improve the quality of power supply, it is necessary to design the substation economically and reasonably, and to achieve the required requirements for the configuration of electrical equipment. For newly-built substations, it is generally required that the substation equipment can operate stably and reliably, be flexible in operation, and invest economically and reasonably. Considering the later development, the space for expansion and upgrading is reserved. This design mainly designs a 35KV step-down substation, which considers the voltage levels of 35KV and 6KV . According to the general steps of substation design, first of all, considering the load grade and calculation in this area, the reactive power compensation calculation and selection of the substation are carried out, the form of the substation is determined
