电缆桥架结构形式分别有:槽式、托盘式和梯架式、网格式等,由支架、托臂和安装附件等组成。建筑物内的桥架可以单独进行架设,也可以平铺在各种建(构)筑物的支架上,其具有结构简单,造型美观、配置灵活和维修方便等特点。全部零件均需进行镀锌处理,安装在建筑物外露天的桥架。但是呢,桥架在使用中会出现老化现象,那么老化的原因有哪些?我们可以采取哪些工艺防止桥架的老化,下面
山东电缆桥架厂家为大家介绍一下:
The structure of cable tray includes trough type, tray type, ladder type and net type, which is composed of bracket, bracket and installation accessories. The bridge in the building can be erected separately or laid on the supports of various buildings (structures). It has the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts shall be galvanized and installed on the bridge outside the building. However, the bridge will appear aging phenomenon in use, so what are the reasons for aging? What process can we take to prevent the aging of cable tray? The following is the introduction of Shandong cable tray manufacturer:
1.绝缘受潮状况:一般经常出现这种情况,经常出现在直埋或排管里的电缆接头处;
1. Insulation damp condition: generally, it often occurs at the cable joint directly buried or arranged in the pipe;
2.化工原料的腐蚀:假如电缆直接埋在酸碱区域内,往往会构成电缆的腐蚀。铅皮或外护层被腐蚀,维护层因长时间遭受化学腐蚀或电解腐蚀,致使维护层失效,绝缘下降,也会导致电缆毛病;
2. Corrosion of chemical raw materials: if the cable is directly buried in the acid-base area, it will often form the corrosion of the cable. The lead skin or outer protective layer is corroded, and the maintenance layer is subject to chemical corrosion or electrolytic corrosion for a long time, resulting in the failure of the maintenance layer, the decline of insulation, and the cable fault;
3.长时间过负荷运转:当经过超负荷运转,长时间超负荷运转时,过高的温度会加快绝缘的老化,以至绝缘被击穿。
3. Long time overload operation: after overload operation and long time overload operation, too high temperature will accelerate the aging of insulation, and even the insulation will be broken down.
4.电缆接头毛病:电缆接头是整个线路中比较脆弱的部分,由人员直接过错(施工不良)引发的电缆接头毛病时常发作。
山东电缆桥架表示施工人员在制造电缆接头过程中,假如有接头压接不紧。加热不充分等原网,都会导致电缆头绝缘下降,然后引发事端。
4. Cable joint fault: the cable joint is a vulnerable part of the whole line, and the cable joint fault caused by personnel's direct fault (poor construction) often occurs. Shandong cable bridge said that the construction personnel in the process of manufacturing cable joints, if there is a joint crimping is not tight. If the original network is not heated sufficiently, the insulation of the cable head will drop, and then cause trouble.
5.环境中的温度因素:电缆桥架及其部件周边的外界环境和热源也会构成电缆温度过高.绝缘击穿,严峻的构成爆破起火。
5. Environmental temperature factors: the external environment and heat source around the cable bridge and its components will also cause the cable temperature to be too high, insulation breakdown, and severe explosion and fire.
那么
山东电缆桥架出现这种老化现象时,我们应该怎样进行处理呢?答案是进行镀锌处理,也就是在表面镀上一层铅材料,浸锌作为一种牺牲阳电位来维护阴电位金属的办法,寿命取决于它的腐蚀锌镀层的阻力和腐蚀速度。
So how should we deal with this aging phenomenon of cable bridge in Shandong? The answer is galvanizing, that is, coating a layer of lead on the surface. As a way of sacrificing the positive potential to maintain the negative potential metal, the life of galvanizing depends on its corrosion resistance and corrosion rate.
