Busbar bridge cleaning, maintenance, inspection, repair
A busbar is a conductor that connects the various current-carrying branch circuits in an electrical device. It is a carrier that collects and distributes power, also known as a busbar. It is customary to refer to the conductors of the current-carrying branch circuits in each power distribution unit as bus bars. The role of the busbar is to collect, distribute and transmit electrical energy. Common busbars are available in hard busbars and soft busbars. The busbar bridge is used to connect the switchgear to the cabinet and to connect the switchgear to other electrical equipment.
Second, the process standard
(1) The conductive contact surface of the busbar in the busbar must be in tight contact and fastened with a torque wrench.
(2) The paint is completely uniform, the surface is clean, and no debris is left inside the busbar.
(3) The sealing rubber ring at the joint of the bus bar and the bus bar, the bus bar and the equipment is continuous and complete, and the compaction is even and compact.

2. Steps
(1) Check the appearance of the busbar body: there should be no damage and deformation. The paint is intact.
(2) Internal inspection of busbars: electrical components, insulating ceramics are complete, no damage, cracks and other defects.
(3) Check the busbar housing should have a good grounding device.
(4) Check whether the conductive contact surface of the busbar in the busbar is in tight contact. If it is not tight, tighten it with a torque wrench.
(5) Use a vacuum cleaner to suck the dust out of the bus bar bridge.
Fourth, matters needing attention
(1) After the work is completed, carefully carry the tools with you, clean up the site, and confirm the remaining items.
