课程名称：电气低压系统配电设计 课程概述：本课程专为希望从零开始获取电气低压电力设计经验的学生设计，时长共计10小时。课程内容涵盖低压配电系统设计相关主题。 课程分为几个部分： 1. 第一部分介绍了著名的绘图软件“AutoCAD”，重点讲解不同工具栏选项，帮助学生熟悉其使用。 2. 第二部分全面讲解了使用DIALux软件进行照明设计和照度计算，为后续的照明配电系统设计做准备。 3. 第三和第四部分涉及照明和电力系统的配电，这使学生能够理解如何收集信息并计算连接负荷，以及如何将设计布局反映在面板日程和单线图中。 4. 在课程的第五部分，学生需要进行一系列与低压系统相关的计算，包括变压器、发电机、电缆、断路器的尺寸计算、电压降、短路电流水平和功率因数校正，以确保整个系统的安全设计，并将计算值反映在项目的单线图中。 5. 第六部分详细解释这些计算，使用简单步骤进行手动计算，以及借助预定义的Excel表格解决不同公式问题。 6. 最后部分讨论接地和防雷系统，强调其不同类型、组件及设计方法，遵循国际标准。 此外，课程中通过展示不同电气设备在现场安装的图片，解释设计与实际安装之间的联系，增强了设计主题的理解。同时课程配备了多种有用资源供学生参考。 总之，本课程的各部分按照相关阶段递增排列，从第一部分引入AutoCAD开始，最终在最后阶段详细解释接地和防雷系统的设计。
This course is dedicated to students looking to acquire electrical low-voltage power design experience from scratch.This course covers low voltage distribution system design-related topics for a total duration of 10 hours.Essentially, the course begins section 1 by introducing the well-known drawing software "AutoCAD" and emphasizing its different toolbar options to prepare the student to be familiar with its use. Consequently, lighting design and lux calculations using DIALux software are fully explained in section 2 to prepare the lighting distribution system that will be explained and designed as a following step in section 3.After that, lighting & power systems distribution are covered in sections 3 & 4, which in turn prepares the student to understand how to gather information and calculate the total connected loads following the lighting and power designed layouts to be reflected in the panel schedules and single line diagrams which will be explained in the 5th section of this course.Once reaching this stage of the course, you will have to perform a range of low voltage system-related calculations of sizing Transformers, Generators, Cables, Circuit Breakers, calculations of voltage drop and short circuit current levels & power factor correction to ensure a safe design for the entire system for the aim of reflecting the calculated values in the single line diagram of the project. All these calculations will be explained separately in detail using simple steps that you can apply manually and with the help of predefined Excel sheets for solving different formulas in section 6.The last section of this course covers the earthing & lightning system topics, emphasizing their different types, components & the appropriate methods to design these systems following international standards.Furthermore, design topics in this course are explained by exploring pictures of different electrical equipment installed on the site to clarify the bond between the design and real site installations.Besides, the course is enhanced with a variety of helpful resources that are attached to it.In a nutshell, the sections of this course are arranged in ascending relevant stages, starting from section 1, which introduces AutoCAD, and finalizing the course by explaining the earthing & lightning systems which could be designed in the last stages of the design.
