摘要

针对益大商贸大楼用电负荷的现状，以及符合经济、综合技术等各方面因数，确定了该校区10kV变配电所的变压器的类型、台数及容量。主要内容包括：变配电所的负荷的统计；负荷功率因数的确定和拟采取的补偿方案；变配电所所址位置、变压器台数、容量和运行形式的选择；变配电所主接线方案的确定；变配电所的短路计算和高低压设备的选择与校验；以及变配电所的电气照明、防雷与接地的设计等。本论文的设计符合《10kV及以下变电所设计规范》以及《工业与民用配电设计手册》等相关规范，特别注重实用性、先进性、经济性，充分体现了我国供配电技术发展。设备的安装必须按照供配电系统设计规范GB50052－95、10kV及以下变电所设计规范GB50053－94、低压配电设计规范GB50054－95、民用建

筑电气设计规范JGJ/T16－92等国家标准和范围规定，正确选择电器设备及正常情况下的监视系统和正常情况下的保护系统，考虑到各种人身安全的技术措施,接线应满足不同负荷的不中短供电要求。还要对变配电所电气装置布置及照明按照明规范进行设照计，在满足以上的情况满足的条件下，保障设计投资少。关键词：变配电；主接线；负荷计算；无功补偿；电气照明；防雷与接地。

Abstract

The report uses electricity the load present situation in view of YiDa business building ，synthesized the economy, the technology and so on various aspects factor had determined this school needed the transformer type, a number and the capacity. The main contents include: substation load calculation; identify and load power factor compensation scheme to be taken; substation location, transformer station number, capacity, and run the choice of form; substation Main Wiring; variable the distribution of the short-circuit calculations and high and low voltage equipment selection; and substation electrical lighting, lightning protection and grounding. This paper is designed

to meet "10kV and below substation design specifications" and "industrial and civil Distribution Design Manual" and other relevant norms, in particular focus on practicality, advanced, economical, fully reflects the supply and distribution technology. Equipment installation must be in accordance with the power supply and distribution system design specifications GB50052-95, 10 kv and

below GB50053-94 substation design standard, low voltage power distribution design specification GB50054-95, the civil construction electrical design specification (JGJ/T16-92 standard and scope of state regulations, such as the correct selection of electrical equipment and under normal circumstances the surveillance system and protection system under normal circumstances, considering all kinds of safety technical measures, should satisfy the requirement of the different load is not short of power supply wiring. Also of variable power distribution electrical equipment arrangement and the design, the lighting shall be carried out in accordance with the lighting specifications above meet the case, security design and less investment, but not to invest at least for the best solution, because investment quotas may affect the flexibility and economy, so that factory power outages, two-string fiddle factory more economic loss. Connection ways should also be considered to meet the needs of present and future development needs.

Keywords: transformation and distribution; main wiring; load calculation; reactive power compensation; electrical lighting; lightning protection and grounding.
