电缆接地箱检验标准评析

网址:www.jiedixiang58.com  2020-07-27  作者:admin    阅读:

缆接地箱的应用范围是十分广泛的,但它在高压电气设备里算是一个比较小的产品,一般收到货后,用户自己其实也可以做一些检测,以保证自己采购的是优质的电缆接地箱。
The application range of cable grounding box is very wide, but it is a relatively small product in high-voltage electrical equipment. Generally, after receiving the goods, users can actually do some testing to ensure that they purchase high-quality cable grounding boxes.
首先接地箱外观应平整美观,稳定性强,箱体无明显焊点,厚度不小于2mm,同批货物箱体和盖子应具有互换性。
First of all, the appearance of the grounding box should be flat and beautiful, with strong stability. The box should have no obvious welding spot, and the thickness should not be less than 2mm. The box and cover of the same batch of goods should be interchangeable.
其次要开盖看一下内部情况,接地箱里面最重要的就是电缆护层保护器,一定要看一下保护器的工艺情况,工艺好的话,性能也不会差的,另外装置内部连接排应采用紫铜排,整体布局设计应合理,空间安全距离应保证,进线管内径最好不小于42mm。
Secondly, it is necessary to open the cover to see the internal situation. The most important thing in the grounding box is the cable sheath protector. If the process is good, the performance will not be bad. In addition, the internal connection row of the device should be copper bar, the overall layout design should be reasonable, the space safety distance should be guaranteed, and the inner diameter of the incoming pipe should be no less than 42mm.
最后要看一下整个接地箱的密封性、防水性等,密封圈应整体密封,将管口密封好后接地箱至于水面下0.5米,1小时内不应出现泄露现象。
Finally, we should check the sealing and waterproof performance of the whole grounding box. The sealing ring should be sealed as a whole. After sealing the pipe orifice, the grounding box should not leak within 1 hour when it is 0.5 meters below the water surface.
以上是检测电缆接地箱的一些常用标准,希望对您能有帮助。

The above are some common standards for testing cable grounding box, I hope it can help you.
