电缆桥架的接地线是直接接地的导线,也可以称为回路。当危险发生时,它被认为是一条生命线,通过将高压直接输送到地面。因此,保护桥架式电缆桥架的地线非常重要。
The grounding wire of Jinan cable bridge is a directly grounded conductor, which can also be called safety circuit. When a hazard occurs, it is considered a lifeline by delivering high pressure directly to the ground. Therefore, it is very important to protect the ground wire of cable tray.
绝缘不良或潮湿环境会导致托盘式电缆桥架设备外壳产生一定量的静电,严重时会发生触电事故。为防止发生意外,可以将电线接到桥架式走线槽的金属表面,并将电线的另一端接地。如果电缆漏电,地线会将电源接地并释放。
Poor insulation or humid environment will lead to a certain amount of static electricity in the shell of tray type cable tray equipment, and electric shock accidents will occur in serious cases. In order to prevent accidents, the wire can be connected to the metal surface of the bridge type trunking and the other end of the wire can be grounded. If the cable leaks electricity, the ground wire will ground the power supply and release it.
如何保护电缆桥架系统中的接地线?

当意外电压施加到断开的设备和线路时,它是保护和认证操作员的重要工具。根据颁布的相关规定,电缆桥架的接地线需要采用直径为4mm以上的裸铜软线。
When unexpected voltage is applied to disconnected equipment and lines, it is an important tool for protecting and certifying operators. According to the relevant regulations issued, the grounding wire of cable tray needs to use bare copper flexible wire with a diameter of more than 4mm.
使用过去的托盘式电缆桥架系统构建接地干线电路时,需要满足以下要求:
When using the past tray cable tray system to build the grounding trunk circuit, the following requirements need to be met:
1、线槽桥架式电缆桥架、桥架桥架式电缆桥架、阶梯桥架式电缆桥架的端接头接触电阻不应大于0.00033。接地孔不得有绝缘涂层。
1. The contact resistance of end joints of trunking type cable tray, bridge type cable tray and ladder type cable tray shall not be greater than 0.00033. The grounding hole shall not have insulating coating.

2、膨胀节或连续铰链用编织铜线。截面积应根据工程实际接地系统和现行相关标准确定。
2. Braided copper wire for expansion joint or continuous hinge. The cross-sectional area shall be determined according to the actual grounding system of the project and the current relevant national standards.
3、沿桥架式桥架全长敷设地线时,桥架式桥架和梯形桥架的所有段(包括非直段)应该牢固地与地线连接.接地线
3. When laying the ground wire along the full length of the bridge type bridge, all sections (including non straight sections) of the bridge type bridge and trapezoidal bridge shall be firmly connected with the ground wire ground wire
4、接地部分的连接螺栓需要有垫圈。
4. The connecting bolts of the grounding part shall be provided with washers.

济南电缆桥架的接地线对于导出静电或者其他额外电压起着关重要的作用,所以对其的保护也就非常重要了
The grounding wire of Jinan cable bridge plays a vital role in deriving static electricity or other additional voltage, so its protection is also very important
