**课程名称：** 开关柜基础及总体布置图绘制 **课程概述：** 本课程是一门基础入门课程，旨在教授学员开关柜及其总体布置图（GA图）的绘制。课程从最基础的概念讲起，逐步深入，涵盖了设计低压开关柜总体布置图所需的各种知识。本课程也适合对开关柜或控制面板感兴趣的学生。 **课程主要内容：** 1. **开关柜基础与总体布置图：** * 什么是总体布置图？ * 总体布置图的应用场景。 * 为何需要绘制电气面板布局图？ * 绘制总体布置图所需的输入信息。 * 总体布置图的变体。 * 开关柜或总体布置图的基本组成模块。 2. **馈线/模块/功能单元：** * 馈线/模块/功能单元基础知识。 * 不同馈线类型：进线、母线联络、出线、电机馈线等。 * 馈线/模块尺寸确定的基本考虑因素。 * 馈线布局的基本考虑因素。 3. **开关设备：** * 空气断路器(ACB)、塑壳断路器(MCCB)、其他面板安装组件、门安装组件、发热设备等。 * 这些组件如何影响馈线尺寸，进而影响开关柜内的布局？ * DIN导轨安装组件的考虑。 * 电流互感器(CT)和电压互感器(PT)的安装与布局考虑。 * 发热设备对布局的影响。 * 联锁装置如何影响馈线布局。 4. **IP防护等级：** * 什么是IP防护等级？ * IP防护等级的重要性。 * IP防护等级在电气开关柜中的意义。 * IP防护等级两位数字的含义。 * 适用于电气开关柜（电机控制中心和动力控制中心）的IP防护等级。 * 不同IP防护等级的含义：IP42、IP54、IP55等。 * IP防护等级如何影响通风设计。 5. **电器分隔形式：** * 什么是电器分隔形式？ * 电器分隔的必要性。 * 各种电器分隔形式。 6. **面板设计的不同变体及其对总体布置图的影响：** * 单机柜设计。 * 多机柜设计。 * 选择特定面板设计的基础。 * 全高馈线。 7. **垂直引线额定值、尺寸与需求系数：** * 垂直引线额定值如何确定。 * 什么是需求系数。 * 支撑点(SUP)与主支撑点(MUP)的各种可能性。 * 为何选择特定设计。 * 总垂直馈线数量。 * 最优馈线布局。 **实践练习：** 课程包含实践练习，帮助学员巩固所学知识。
Electrical Control panel - Basics & considerations for general arrangement (GA) drawings for Switchboard / control panel /Electrical PanelsElectrical Switchboard / control panel designBasics on Switchboards & their General Arrangement drawings is a basic course to start learning about switchboard or their general arrangement drawings. We have covered various concepts that are required to design general arrangement drawings for low voltage switchboards. We start with very basics and eventually build on it. This course is even suitable for students who want to learn about the switchboards or control panels.Some of the topics that you will come across are: 1) Basic details on Switchboards & GA Drawings What is GA drawing? Where is it used ?Why are electrical panel layout drawings needed? What are the inputs required to draw a GA drawing? Variations in GA drawings Basic Building blocks of a Switchboard or GA drawings. 2) Feeders / Modules/ Functional Units Basics on feeders / modules /functional units. Different feeder types: Incomer / Bus-coupler / Outgoings / Motor Feeders etc. Basic considerations for feeder sizing / module sizing Basic considerations for feeder placement 3) Switchgear - ·ACB's, MCCB's, Other plate mounted components, door mounted components, Heat generating equipments etc. How they affect the feeder sizing and, in turn, affect the placement in Switchboards Consideration for din-rail mounted components Consideration for mounting and placement of CT's & PT's Heat generating equipments How interlocks affect feeder placement4) IP Protection What is IP protection?Why is it important?How is it important for Electrical Switchboards?What is the significance of the 2 digits in IP rating?IP's Applicable for Electrical Switchboards - Motor Control Centers and Power control centersWhat various IP's mean: IP 42, IP 54, IP 55 etc.How IP protection impacts ventilation arrangement 5) Form of Segregation What form of segregation is?Why segregation is required ?What are the various forms of segregation?6) Different variations of panel design and how they define the GA drawing Single unit panelsMulti unit panelsOn what basis is a particular design of panel selected?Full height feeders7) Vertical dropper rating and sizing & diversity factor. And lastly Practice ExerciseHow vertical dropper rating is decided.What is diversity factorSUP's & MUP's - Various possibilitiesWhy a certain design is selectedTotal vertical count Optimum feeder placement
