電纜橋架作為線路鋪設(shè)工程中的重要配套設(shè)施，在配電中起著重要的作用，但有時(shí)橋架也會(huì)出現(xiàn)一些故障，給我們帶來一定的麻煩，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.

電纜橋架使用中常見的問題是短路，這可能是電纜內(nèi)部短路或電纜燒毀造成的。一般來說，電纜質(zhì)量太低。電纜橋架在使用過程中會(huì)膨脹和收縮。例如，鋼制電纜橋架會(huì)因環(huán)境溫度的變化而受熱膨脹，受冷收縮。室外橋架的效果受溫度影響很大。因此，在使用過程中要注意溫度的變化。

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.

電纜內(nèi)部有短路。此類故障的主要原因是購買的電纜質(zhì)量差，表面不會(huì)有任何痕跡。在這種情況下，我們可以更換電纜。平時(shí)購買電纜時(shí)，一定要注意購買質(zhì)量可靠的產(chǎn)品。如果為了省點(diǎn)錢而使用劣質(zhì)電纜，可能會(huì)出現(xiàn)大面積短路，造成巨大的隱患。這樣一來，就得不償失了。

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.

小編提醒大家，安裝電纜橋架前，不僅要滿足要求的荷載撓度，還要根據(jù)建筑物的結(jié)構(gòu)特點(diǎn)、計(jì)算的荷載、橋架的尺寸和撓度等考慮安裝的便利性，以及確定合適的跨度。橋架安裝的準(zhǔn)備工作是在兩個(gè)橋臺(tái)之間架設(shè)腳手架，并鋪設(shè)鞍板作為氣動(dòng)球閥的鋼橋安裝平臺(tái)。裝載機(jī)將用于從橋臺(tái)到兩側(cè)施工道路的場地平整。畫出院線并標(biāo)明橋架部件、附件和安裝工具的堆放位置。

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.

如果電纜橋架設(shè)備生產(chǎn)的產(chǎn)品質(zhì)量不合格，檢查模具內(nèi)是否有異物，并及時(shí)清理異物。還要檢查低壓壓力設(shè)定的情況，壓力設(shè)定是否合適，低壓設(shè)定位置的位置是否正確。如果沒有發(fā)現(xiàn)問題，檢查電纜橋架設(shè)備的動(dòng)作順序是否正確。在手動(dòng)操作的情況下，必須先合模，然后再向前移動(dòng)。

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.

當(dāng)山東電纜橋架發(fā)生故障時(shí)，我們需要以正確的方式進(jìn)行處理，以免處理不及時(shí)造成損失。減少橋架故障的發(fā)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.
