Refractory busway manufacturers tell you the maintenance of busway


BusbarIn the daily use of the process is also the need for repair and maintenance, then, what should we do?Fire-resistant bus duct manufacturersto give you a brief introduction.

11. Regular maintenance work can be carried out at least once a year during long-term operation of bus duct.

2Check that the total load current does not exceed the design current and the rated current of the main busbar.

32. Check the system for power failure before maintenance! Cut all the power! Use a multimeter to measure the wire voltage and confirm that the bus duct system is not charged before routine maintenance.

4,BusbarDuring operation, you should check whether there is leakage, water spray, potential moisture sources, whether there are heavy objects that pose a threat to the system, and heat sources that affect the temperature rise of the bus duct system. Check whether the parts of the bus duct system are damaged or corroded. If any damage is found, replace them immediately.





51. The temperature rise of the joint shall be detected regularly once a year during the long-term operation of the bus duct. Check whether the connecting bolts of all busway joints and the contact parts of conductors are loose. To prevent the resistance due to loose conditions caused by the increase in the quality of the joint cause of heating phenomenon. Check the insulation structure materials of the equipment and whether there is aging phenomenon, and whether the conductive capacity part has melting deformation phenomenon. If interphase grounding and insulation breakdown are found, they should be removed in sections and checked in sections with a withstand voltage tester to find out the fault, or re-select and replace the bus duct, or redesign to study insulation coating treatment.


6The busbar channel system regularly removes dust on the surface to ensure good heat dissipation.

71. After the maintenance work is completed, the insulation resistance shall be checked and a complete maintenance process record shall be kept before re-power transmission.

Above isFire-resistant bus duct manufacturerstell youBusbarMaintenance, I hope to help you.
