绝缘和水分。
Insulation and moisture.
通常,这相对常见,通常在直接埋地或激励的电缆接头处产生。例如:电缆桥架接头不合格,接头在湿气态条件下进行,接头是入口或混合到水蒸气中,在电场效应下构成水树枝,电缆的绝缘强度逐渐伤害。
Usually, this is relatively common and usually occurs at cable joints directly buried or excited. For example, if the cable tray joint is unqualified, the joint is carried out under the wet gas condition. The joint is imported or mixed into the water vapor, forming a water tree under the effect of the electric field, and the insulation strength of the cable is gradually damaged.
化学原料的腐蚀。
Corrosion of chemical raw materials.
电缆桥架直接埋在酸基效应区域。它通常构成电缆的装甲,铅或外护套,这导致由于长时间导致化学腐蚀或电解腐蚀,导致保护层失效,绝缘,并且它也将导致电缆缺点。
The cable tray is directly buried in the acid base effect area. It usually constitutes the armor, lead or outer sheath of the cable, which leads to the failure of the protective layer and insulation due to long-term chemical or electrolytic corrosion, and it will also lead to cable defects.
长时间超负荷运载。
Long time overload.
由于电流的热效应,负载电流肯定会导致导体的发热,同时充电,以及钢制甲的涡流损失,以及绝缘介质损失也可以是添加,然后温度增加。当过载运行很长时间时,过高的温度加速了绝缘的年龄,使绝缘体被打破。特别是在炎热的夏天,电缆的温度升高常常导致电缆绝缘的初级击穿单位,所以在夏季,电缆的缺点很多。
Due to the thermal effect of the current, the load current will certainly lead to the heating of the conductor, the charging at the same time, the eddy current loss of the steel armour, and the loss of the insulating medium can also be added, and then the temperature increases. When overloaded for a long time, the excessive temperature accelerates the age of insulation and breaks the insulator. Especially in hot summer, the temperature rise of the cable often leads to the primary breakdown unit of the cable insulation. Therefore, in summer, the cable has many disadvantages.
电缆连接器的缺点。
Disadvantages of cable connectors.
桥接接头是电缆线的更薄,这通常由由人员直接疏忽(消费)引起的电缆接头的缺点产生。在制造电缆连接的过程中,施工人员可能导致电缆头减少,然后触发没有足够网络的电缆头的解释。
The bridging joint is the thinner of the cable, which is usually caused by the shortcomings of the cable joint caused by the direct negligence (consumption) of personnel. In the process of manufacturing cable connections, the construction personnel may cause the cable head to be reduced, and then trigger the explanation of cable head without sufficient network.
环境和温度元素。
Environmental and temperature elements.
山东电缆桥架和电缆周围的外部环境和热源也将构成电缆温度,绝缘击穿和严重的组成爆炸。
Shandong cable tray and the external environment and heat source around the cable will also constitute cable temperature, insulation breakdown and serious composition explosion.
外力危险。
Danger of external force.
目前的电缆缺点主要由机械危害引起。例如,请参阅:当使用电缆时,请勿标准化构造,并简单地构成机械危险;在直接埋葬电缆中易于参与土木工程。在某些情况下,电缆的危害并不严重。也许几个月或几年可能有一个缺点的有害部分的缺点,电缆损坏较重可能产生短路短路缺点,直接影响电缆桥架。
Current cable disadvantages are mainly caused by mechanical hazards. For example, please refer to: when using cables, do not standardize the structure, and simply constitute a mechanical hazard; It is easy to participate in civil engineering in direct buried cables. In some cases, the cable hazard is not serious. There may be a defect in the harmful part of a defect in a few months or years. If the cable is seriously damaged, it may cause short circuit, which will directly affect the cable tray.
