电气图的分类1.Overview概述电气图是电气工程图的简称。电气图的主要作用是用来阐述电气系统的工作原理，描述产品的构成和功能，是提供装接和使用信息的重要工具主手段。电气工程图是按照统一的规范规定绘制的，采用标准图形和文字符号表示实际电气工程安装、接线、功能、原理及供配电关系的简图。Electricalengineeringdrawingisdrawninaccordancewiththeunifiedspecifications,usingstandardgraphicsandsymbolstorepresenttheactualelectricalengineeringinstallation,wiring,functions,principlesandpowersupplyanddistributionrelationsdiagram.Themainfunctionofelectricaldiagramistoexplaintheworkingprincipleoftheelectricalsystem,describethecompositionandfunctionoftheproduct,istoprovideanimportanttoolandmainmeansofassemblyanduseinformation.Electricaldrawingisshortforelectricalengineeringdrawing.

按国家标准GB/T6988.1~6的规定，电气图大致可分为19种，常用的主要有以下几种。
