The function of grounding wire and the correct use method
1、地线的作用—地线


1. The action of the ground line - the ground line
地线，又称避雷线，是指用来将电流引入大地的导线;电气设备漏电时，电流通过地线进入大地。地线的符号是E(Earth);可分为供电地线、电路地线两种。按我国现行标准，GB2681中第三条依导线颜色标志电路时，一般应该是相线—A相黄色，B相绿色，C相红色。零线—淡蓝色，地线是黄绿相间，如果是三相插座，左边是零线，中间(上面)是地线，右边是火线。春晨电机引接线电机引出线801​


The ground wire, also known as the lightning conductor, refers to the conductor used to introduce the electric current into the earth. When the electrical equipment is leaks, the current flows through the earth's wire into the earth. The symbol of ground wire is E (Earth), which can be pided into two kinds: power supply ground wire and circuit earth wire. According to our current standard,

in third of GB2681, according to conductor color marking circuit, it should be phase line A phase yellow, B phase green, C phase red. The zero line is light blue, the ground wire is yellow green, if it is a three-phase socket, the left side is zero line, the middle (above) is the ground wire, and the right side is the fire line.

2. The effect of ground line - Grounding symbol
在现代接地概念中、对于线路工程师来说，该术语的含义通常是‘线路电压的参考点’;对于系统设计师来说，它常常是机柜或机架;对电气工程师来说，它是绿色安全地线或接到大地的意思。一个比较通用的定义是“接地是电流返回其源的低阻抗通道”。下面为大家介绍几种常见的接地符号


In modern grounding concepts, for line engineers, the term is usually a 'reference point' for line voltage; for a system designer, it is often a cabinet or a rack; for electrical engineers, it is a green safe ground line or the meaning of receiving the earth. A more general definition is "grounding is the low impedance channel of current returning to its source". Here are some of the common grounding symbols
