What are the busbar system advantages?
Busbar system advantages:
(1)The busbar system improve the reliability of power supply. Operating experience shows that due to external bare
busbar and contact conductor interphase short circuit, causing a major accident. The isolated phase bus not only
eliminate the external contact due to different phase conductor and interphase short circuit fault caused, but also
effectively prevent the short-circuit caused by relatively short circuit; at the same time, because of the influence of
closed bus insulator from dust and moisture, ground fault opportunities are greatly reduced.
(2)One of busbar system advantages that due to the magnetic field lines produced by shell became almost all the housing circulation is actually completely shielding, eliminating the problem of induction heating steel near the bus, to avoid a lot of power loss, improve the working conditions of equipment.
(3)Greatly reducing the power of the bus. Due to the electric shielding effect of the outer shell, the electric power of the bus is greatly reduced when a short circuit fault is in short circuit, and only 20% to 30% of the bare bus bar can be reduced. The working conditions of the equipment (conductor, insulator, current transformer, isolating switch, etc.) are improved, so that the capacity of the equipment can meet the requirement of dynamic stability.
(4) Operation safety and easy maintenance. The casing of the whole bus bar is basically equal potential, and the casing is provided with a connecting point, so that the operator can not be subjected to high voltage when the shell is close to the shell, and the daily maintenance workload is less.
(5) The last busbar system advantages is that installation of the workload is small. Enclosed busbar system is in the factory set a good system, only need to complete each prefabricated bus transported to the site, the connection can be assembled, thus accelerating the construction progress.
