电缆桥架作为线路铺设工程中的重要配套设施，在配电中起着重要的作用，但有时桥架也会出现一些故障，给我们带来一定的麻烦，比如短路。在下面找到。

As an important supporting facility in the line laying project, the cable tray plays an important role in the power distribution. However, sometimes the cable tray will have some faults, which will bring us some trouble, such as short circuit. Found below.

电缆桥架使用中常见的问题是短路，这可能是电缆内部短路或电缆烧毁造成的。一般来说，电缆质量太低。电缆桥架在使用过程中会膨胀和收缩。例如，钢制电缆桥架会因环境温度的变化而受热膨胀，受冷收缩。室外桥架的效果受温度影响很大。因此，在使用过程中要注意温度的变化。

The common problem in the use of cable tray is short circuit, which may be caused by internal short circuit or cable burnout. Generally speaking, the cable quality is too low. The cable tray will expand and contract during use. For example, the steel cable tray will expand and contract due to the change of ambient temperature. The effect of outdoor cable tray is greatly affected by temperature. Therefore, pay attention to the change of temperature during use.

电缆内部有短路。此类故障的主要原因是购买的电缆质量差，表面不会有任何痕迹。在这种情况下，我们可以更换电缆。平时购买电缆时，一定要注意购买质量可靠的产品。如果为了省点钱而使用劣质电缆，可能会出现大面积短路，造成巨大的安全隐患。这样一来，就得不偿失了。

There is a short circuit inside the cable. The main reason for this kind of failure is that the purchased cable is of poor quality and there is no trace on the surface. In this case, we can replace the cable. When purchasing cables at ordinary times, we must pay attention to purchasing products with reliable quality. If inferior cables are used to save money, a large area of short circuit may occur, resulting in a huge potential safety hazard. In this way, the gains are not worth the losses.

小编提醒大家，安装电缆桥架前，不仅要满足要求的荷载挠度，还要根据建筑物的结构特点、计算的荷载、桥架的尺寸和挠度等考虑安装的便利性，以及确定合适的跨度。桥架安装的准备工作是在两个桥台之间架设脚手架，并铺设鞍板作为气动球阀的钢桥安装平台。装载机将用于从桥台到两侧施工道路的场地平整。画出院线并标明桥架部件、附件和安装工具的堆放位置。

The editor reminded us that before installing the cable tray, we should not only meet the required load deflection, but also consider the convenience of installation and determine the appropriate span according to the structural characteristics of the building, the calculated load, the size and deflection of the tray, etc. The preparation for bridge installation is to erect scaffold between two abutments and lay saddle plate as the steel bridge installation platform for pneumatic ball valve. The loader will be used for site leveling from the abutment to the construction roads on both sides. Draw discharge lines and indicate the stacking positions of bridge components, accessories and installation tools.

如果电缆桥架设备生产的产品质量不合格，首先检查模具内是否有异物，并及时清理异物。还要检查低压压力设定的情况，压力设定是否合适，低压设定位置的位置是否正确。如果没有发现问题，检查电缆桥架设备的动作顺序是否正确。在手动操作的情况下，必须先合模，然后再向前移动。

If the product quality produced by the cable tray equipment is unqualified, first check whether there is any foreign matter in the mold, and clean the foreign matter in time. Also check the low pressure setting, whether the pressure setting is appropriate, and whether the low pressure setting position is correct. If no problem is found, check whether the action sequence of cable tray equipment is correct. In the case of manual operation, the mold must be closed first and then moved forward.

当 山东电缆桥架发生故障时，我们需要以正确的方式进行处理，以免处理不及时造成损失。减少桥架故障的发生。

When Shandong cable tray breaks down, we need to handle it in a correct way to avoid losses caused by untimely handling. Reduce the occurrence of bridge failure.
