电缆桥架电缆老化的原因是什么?
电缆桥架绝缘层被单独的外壳覆盖。一旦防护效果不好,长时间暴露在空气中,绝缘层将大大减少,并且随着年龄的增长,绝缘层将逐渐硬化直秋天。此时,绝缘效果不佳。通常,电缆绝缘是由橡胶和塑料制成的,那么其老化原因是什么?
The cable tray insulation is covered by a separate shell. Once the protective effect is not good and exposed to the air for a long time, the insulating layer will be greatly reduced, and with the growth of age, the insulating layer will gradually harden until autumn. At this time, the insulation effect is poor. Usually, cable insulation is made of rubber and plastic, so what is the reason for its aging?
接头通常出现在埋入电缆中,或者在这种情况下出现在排气管中。我们可以举个例子。当电缆接头的不合格产品处于潮湿环境时,接头会发展成土壤或水蒸气。此时,如果有电场,防火电缆桥架学生将逐渐形成直接影响电缆绝缘的水树。从而引起了引起失败的公司的问题。
Connectors usually appear in buried cables or, in this case, in exhaust pipes. We can give an example. When the unqualified products of cable joints are in a humid environment, the joints will develop into soil or water vapor. At this time, if there is an electric field, the fireproof cable bridge will gradually form a water tree that directly affects the cable insulation. This has led to the problems of failed companies.
化学原料的腐蚀。对于埋入式电缆,这将直接导致电缆载体铠装电缆N,引线板或外部护套区域发生酸-碱相互作用,然后通过化学和电解蚀刻保护层,随后破坏腐蚀性物质保护层,减少绝缘,还会导致电缆故障。
Corrosion of chemical raw materials. For buried cables, this will directly lead to acid alkali interaction in the armored cable n of the cable carrier, the lead plate or the area of the outer sheath, and then etch the protective layer through chemical and electrolytic etching, and then destroy the protective layer of corrosive substances, reduce the insulation, and also lead to cable failure.
3.长期过载已在运行。
3. Long term overload has been in operation.
就电缆而言,导体会发热。当电缆温度升高时,负载电流将加速绝缘层的老化,直到发生击穿时间。特别是在夏天,电缆桥架的故障将变得更加严重。
In the case of cables, the conductor will heat up. When the cable temperature rises, the load current will accelerate the aging of the insulation layer until the breakdown time occurs. Especially in summer, the failure of cable tray will become more serious.
4.电缆连接器故障。
4. Cable connector failure.
实际上,我们系统的故障应归因于管理人员的不当操作。例如,当施工技术人员使电缆接头开始压接并且加热不充分时,这将导致电缆头的绝缘性能下降。
In fact, the failure of our system should be attributed to the improper operation of managers. For example, when the construction technician starts crimping the cable joint and the heating is insufficient, this will lead to the decline of the insulation performance of the cable head.
5.环境温度系数:
5. Ambient temperature coefficient:
外部环境以及电缆桥架和电缆,高温,绝缘击穿,起火甚爆炸的温度影响。
External environment, cable tray and cable, high temperature, insulation breakdown, fire and even explosion.
6.外部损坏。
6. External damage.
许多电缆故障中的大多数电流是由机械损坏引起的。例如:防火电缆桥架当我们安装的布线施工技术不规范时,很容易在我国造成机械损坏,因为那时有时损坏并不严重,但是经过一段时间的运营成本,它就会开始出现直到形式故障,严重的故障可能导致短路,直接影响到公司生产教育的桥梁和动力单元
Most of the current in many cable faults is caused by mechanical damage. For example, when the wiring construction technology we installed is not standardized, it is easy to cause mechanical damage in China, because sometimes the damage is not serious, but after a period of operation cost, it will begin to appear until formal failure. Serious failure may lead to short circuit and directly affect the bridges and power units of the company's production and education
