本科生毕业 毕业论文题目 小纪电机厂双回路10KV变电所设计 摘要 本设计针对小纪电机厂用电负荷的现状、经济及综合技术，等各方面因数素确定了双回路10kV变配电所的变压器类型、台数及容量。设计主要内容包括：变配电所的负荷计算；负荷功率因数的确定和无功功率补偿；变配电所位置、变压器台数、容量、和运行形式的选择；变配电所主接线方案；变配电所的短路计算和高低压设备的选择；以及变配电所的电气照明、防雷与接地等。根据电气主接线设计应满足可靠性、灵活性、经济性的要求，本变电所电气主接线的高压侧采用单母线接线，低压采用单母线分段的电气主接线形式。 本文设计是针对生产实践，通过分析、计算、比较和论证等设计步骤完成了变电所电气部分设计，能够满足变电所稳定安全供电的要求，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。 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 xiaoji electric motor workhouse, 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. According to the main line of electrical design should meet the reliability, flexibility, economy requirements, The substation main electrical wiring High Side single-bus wiring, low voltage side of the single-bus above the main electrical wiring form; active power loss, increased energy utilization。 This article is designed for the production of practice, through analysis, computation, comparison and verification steps to complete the design of electrical substation design, substation to meet the requirements of a stable and secure power supply，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. Keywords: transformation and distribution; main wiring; load calculatio
