摘要
随着我国工业的发展,各行业对电力系统的供电可靠性和稳定性的要求日益提高。变电站是连接电力系统的中间环节,用以汇集电源、升降电压和分配电能。变电站的安全运行对电力系统至关重要。
本文主要进行110kV/10kV无人值班降压变电站的设计。主要内容包括:变电站电气主接线的设计和选择、短路电流的计算、主变压器和电器设备的选择。其中电器设备的选择主要包括:断路器、隔离开关、PT、CT、支柱绝缘子、套管、母线导体、避雷器、电抗器、高压熔断器等。
本文简单介绍了采用综合自动化设备实现变电站无人值班。
附件包括:变电站电气主接线图、变电站平面布置图、110kV侧进线间隔断面图
关键词降压变电站、电气部分设计、无人值班、综合自动化系统
Abstract
Along with the continuous developing of agriculture and industry in our country,every walk of life’s demand of reliability and stability towards electric power system .They are used to connect the power supplies ascengd or descend the electric voltage ,or distribute electric power .It’s very important to power system that the substation works safely .
This paper main focus on the designing of primary power system in 110/10kV unmanned and step-down substation .The main contents are as follows :the designing and selecting main electrical connection of substation ,calculation of short-circuit current ,selecting of main transformer and electrical equipments primarily includes :circuit-breaker ,disconnecting switch ,potential transformer ,current transformer ,post-type insulator ,busbar conductor ,lighting arrestor etc .
This paper also contains the designing of intergrated automation based unmanned substation .
Affix main contains main electrical connection drawing ,general layout drawing of substation ,fracture surface of 110kV drawing .
Keywords: step-down substation、electrical connection、design unmanned、intergrated automation system
