LED 灯具保护接地的连续性

LED lamps and lanterns of protective earthing continuity 

LED 灯饰上的庇护保护性一定与地面系统端子排与或者成导电的比较容易触碰元器件相互间；庇护保护性一定与地面系统的关键所在是保护性一定与地面系统永远的性和准确性保护性一定与地面系统的多次性，使验测的庇护保护性一定与地面系统多次性电阻值≤0.5 欧。

The protective earthing terminal on the LED lamps and lanterns and could be charged between the most accessible components; Grounding protection is the key to the continuity of grounding permanent and reliability, the detection of protective earthing continuity resistance or less 0.5 euro. 

特别应先要如何判断哪几种组件要呵护等电位连接，最后是改善需要呵护等电位连接的组件与接接线端子之前的持续性。

So the first thing to determine which parts to protect the earth, and then the solution to the need to protect the earth continuity between the parts and connect terminals. 

1、在完成任务led灯具进行安装时可涉及的，而且电绝缘报废时能成为有电的零部件；

1, when to complete the installation of lamps and lanterns palpable, and insulation failure can become electrically charged components; 

2、为灯具清洁而打开时可触及的，并且绝绿失效时可能变为带电的部件；

2, when open the palpable for clean lamps and lanterns, and absolutely green fails may become electrically charged components; 

3、灯具中安全部件所在的金属安装面；

3, lamps and lanterns of the safety components of metal mounting surface; 

4、与灯具中的安全部件(如电线、控制装置)接触的或可能接触的金属表面；

4, with lamps and lanterns of security components (such as electrical wiring, control equipment) or may contact the metal surface; 

5、更重要的是要从结构上去保证它们之间的连续性。

5, what is more important to went up from the structure to ensure the continuity between them. 

6、用黄绿双色线作标识的导体,无论是内部接线还是外部接线,应仅与接地端子连接；

6, with the yellow green double color line for identification of conductor, whether internal or external wiring connection, should be connected to the earthing terminal only; 

7、用自攻螺丝钉可用来保护接地的连续性，只要在正常使用时不会妨碍这种连接，并且每一连接处至少用两只螺钉；

7, with self tapping screws can be used to protect the grounding continuity, as long as in this connection will not interfere with the normal use, and each joint with at least two screws; 

8、用铝和铜不可直接连接接地，会起电化学反应造成接触电阻变大，影响接地连续的低电阻性；

8, with aluminum and copper cannot be directly connected to ground to electrochemical reaction will cause the contact resistance, impact grounding continuous low resistance; 

9、接地电阻的测量，可用测量设备调至 12V，10A 检测，电阻值≤0.5欧。

9, the grounding resistance measurement, measuring equipment is available to the 12 v, 10 a detection, resistance or less 0.5 euro.
