電纜橋架的接地線是直接接地的導線,也可以稱為安全回路。當危險發生時,它被認為是一條生命線,通過將高壓直接輸送到地面。因此,保護橋架式電纜橋架的地線非常重要。
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.
絕緣不良或潮濕環境會導致托盤式電纜橋架設備外殼產生一定量的靜電,嚴重時會發生觸電事故。為防止發生意外,可以將電線接到橋架式走線槽的金屬表面,并將電線的另一端接地。如果電纜漏電,地線會將電源接地并釋放。
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.
如何保護電纜橋架系統中的接地線?
How to protect the grounding wire in Jinan cable tray system?
當意外電壓施加到斷開的設備和線路時,它是保護和認證操作員的重要工具。根據頒布的相關規定,電纜橋架的接地線需要采用直徑為4mm以上的裸銅軟線。
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.
使用過去的托盤式電纜橋架系統構建接地干線電路時,需要滿足以下要求:
When using the past tray cable tray system to build the grounding trunk circuit, the following requirements need to be met:
1、線槽橋架式電纜橋架、橋架橋架式電纜橋架、階梯橋架式電纜橋架的端接頭接觸電阻不應大于0.00033。接地孔不得有絕緣涂層。
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、膨脹節或連續鉸鏈用編織銅線。截面積應根據工程實際接地系統和現行相關國家標準確定。
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、沿橋架式橋架全長敷設地線時,橋架式橋架和梯形橋架的所有段(包括非直段)應該牢固地與地線連接.接地線
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、接地部分的連接螺栓需要有墊圈。
4. The connecting bolts of the grounding part shall be provided with washers.

濟南電纜橋架的接地線對于導出靜電或者其他額外電壓起著至關重要的作用,所以對其的保護也就非常重要了
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
