不同气候的环境选用不同的环境登记铝合金桥架的参数、按温度、湿度、防火情况决定。下面
江南app官方入口在哪里看到厂家给您讲解下铝合金桥架使用过程中的四种故障。
Different environmental registration parameters of aluminum alloy bridge shall be selected for different climates, which shall be determined according to temperature, humidity and fire protection. Next, the manufacturer of Jinan cable tray will explain to you four kinds of failures in the use of aluminum alloy cable tray.
一种故障是电缆桥架各相短路。同样,这种故障也会导致配电柜上的电流继电器和电压继电器工作,并且电缆在故障点处受到严重损坏。
One fault is short circuit of each phase of cable tray. Similarly, this kind of fault will also cause the current relay and voltage relay on the power distribution cabinet to work, and the cable will be seriously damaged at the fault point.
二种故障是电缆桥架内部短路,外部看不到。这种故障通常是由电缆的质量引起的。
The two faults are short circuit inside the cable tray, which cannot be seen from the outside. This fault is usually caused by the quality of the cable.
三种故障是整个电缆烧坏或某一相烧坏。这种故障引起配电柜上的电流继电器动作,故障时电缆损坏严重。
The three faults are the whole cable burnt out or one phase burnt out. This kind of fault causes the current relay on the power distribution cabinet to act, and the cable is seriously damaged when the fault occurs.
四种故障是电缆桥架只有一个断相电路,电流继电器工作。故障点的损伤较轻,但暴露更明显。可能是相电流太大,或者是电缆质量造成的。
The four faults are that the cable tray has only one open phase circuit and the current relay works. The damage of the fault point is less, but the exposure is more obvious. It may be caused by too much phase current or cable quality.
此外要知道电缆桥架在有防火要求的区段内,可在电缆梯架,托盘内添加具有耐火或难燃性能的板,网等材料构成封闭或半封闭式结构,并采取在电缆桥架及其支吊架表面涂刷防火涂层等措施,其整体耐火性能应满足有关规范或标准的要求。在工程防火要求较高的场所,不宜采用铝合金电缆电缆桥架。
In addition, it should be known that in the section with fire protection requirements, the cable ladder and tray can be added with fire-resistant or flame-retardant plates, nets and other materials to form a closed or semi closed structure, and measures such as painting fire-resistant coatings on the surface of the cable tray and its supports and hangers should be taken. The overall fire resistance should meet the requirements of relevant national codes or standards. In places with high fire protection requirements, aluminum alloy cable trays should not be used.
After understanding the cause of cable tray failure, it is more convenient to find a solution to the problem. Friends with problems can contact us at any time //www.comprepyme.com Contact.
