As an intelligent weak current system, tray bridge plays an important role in our daily life. But it often shows some problems and causes chaos in our lives. So, do we know what problems the cable bridge will encounter? For example, all parts of the cable tray show short circuit.
This kind of fault may cause the current relay on the distribution cabinet to act, and the cable damage is very serious. The internal short circuit of the cable is usually caused by the low quality of the cable. There will be no trace on the surface.
It seems that the whole cable is burnt or the cable is burnt, which causes serious damage to the cable in case of failure; It may be that there is only one short circuit in the cable bridge, and the cable at the fault is damaged by the lighter, but there are still obvious traces.
The cause of such problems may be too high current or poor cable quality. All mechanical equipment must be inspected and maintained regularly after use. The bridge manufacturer will discuss how to repair and maintain the cable bridge equipment.
Test and check the movement of the balance cylinder of the cable bridge equipment and the oil circuit and joint of the oil lubrication system. The friction between the sliding block and the guide rail of the tray type bridge is relatively frequent. Necessary adjustment should be made to check the lubrication quality of the joints and pipes to ensure good operation.
Regularly lubricate the gear components of the cable bridge equipment: the gearbox and internal components are more vulnerable to damage due to frequent operation, and the possibility of loosening is greater.
In addition, before the commencement of the tray type cable bridge, go to the construction site for field survey, determine which bridges need to be replaced, make a form and make detailed records. When everything is ready, the construction of tray type cable bridge begins. The use of lifting belt during lifting can prevent the construction personnel and intact cables from being damaged.
During the replacement of tray type cable bridge, special personnel shall be assigned to protect it to prevent irrelevant personnel from approaching the construction site. Remove the severely corroded cable tray and install a new cable tray. Restore the cable to its original position, tray the cable tray and replace a section. After everything is the same as before, replace one section, and then replace another section. Is there anything you don't understand?
