题 目 红旗 机械厂总降压变电所 及高压配电系统设计 摘 要在当前的工业时代中，人们要求拥有稳定可靠的电力供应。科学合理的设计变电所，完成变电所的合理配置，才能够有效增强电网的可靠性、稳定性和持续性。一个典型的变电所，必然需要具备运行可靠且操作灵活的变电设备，能够保证变电所成本合适，且扩建方便。正是出于上述几方面考虑，本文结合某机械厂的原始资料，设计了该机械厂中的变电所、高压配电系统。根据设计任务书，在本文的设计方案中，包括高压配电系统的电器主接线方案、变电所地址。对于各种方案进行对比分析后，变电所的电气主接线将采用双母线接线，总降压变电所主要装备一台主变压器，为 35kV 电压的工作电源，其备用电源的电压为 10kV。根据设计方案选择了恰当的高压电气设备、变压器、继电保护装置、二次回路方案、接地和防雷保护。关键词：变电所 高压电气设备 短路电流 变压器 继电保护Machine factory total voltage dropping transformer substation and the high pressure electrical power distribution system Designs AbstractIn the current industrial era, people require a stable and reliable power supply. Scientific and reasonable design of substation and reasonable configuration of substation can effectively enhance the reliability, stability and sustainability of power grid. For a typical substation, it is necessary to have reliable and flexible substation equipment, which can ensure that the cost of the substation is appropriate and the expansion is convenient. It is for the above considerations, this paper combined with the original data of a mechanical plant, designed the substation and high-voltage distribution system in the mechanical plant. According to the design specification, in the design scheme of this paper, including the main electrical wiring scheme of high-voltage distribution system, substation address. After the comparison and analysis of various schemes, the main electrical wiring of the substation will adopt double bus wiring. ...
