35kV变电站电气一次部分设计技术分析

Electrical Primary Research and Design of 35 kV Substation

基于35kV变电站设计的相关国家规范、手册、标准,该课题实现了35kV终端降压变电站电气一次部分的研究与设计。35kV侧母线采用单母线接线并采取1回进线方式,主变压器采用2台SZ9-8000/35型有载调压变压器;10kV侧母线采用单母线简易分段接线并有8回出线;10kV主进线采用ZN28-12型真空断路器,出线采用断路器与保护控制器配合作为控制和保护,本课题的研究结合新时代的要求,并采用新技术及节能设计原则,对于进一步提高变电站电气系统优化设计具有一定借鉴意义,便于今后变电站工程的设计,提高工作效率。

Based on national standard about the design of 35 k V substation, manuals, standards and the subject for 35 k V terminal step-down transformer substation electrical primary research and design. 35 k V bus side with single busbar connection and take a way back into the line, the main transformer adopts two SZ9-8000/35 on-load voltage regulating transformer; 10 k V side with simple single busbar of busbar and eight back line; 10 k V main feed line the ZN28-12 type vacuum circuit breaker, wire controller circuit breaker and protection, is employed as control and protection, this topic research combined with the requirements of the new era, and adopt new technologies and energy-saving design principles, to further improve the substation electrical system optimization design, have certain reference significance to facilitate the future substation project design, improve the work efficiency.
