Sustainable Mining and Metallurgy

This article compared two temporary short-circuiting busbar schemes: busbar along the passage and across each cell section. Along the passage temporary short-circuiting busbars are suitable for new plants, and enables section-by-section start-up/shut-down; across-section busbars are suitable for operating plants, particularly adaptable to cases where the cells to be shutdown are located in the middle of a section; both schemes can be installed alone, and together as well. Both schemes also show good economic performance, with a short payback period. In particular, the along-the-passage scheme provides considerable benefits. Both schemes are also quite safe and highly operable, and reliable in their technology. Apart from sound economic performance, the across-sections scheme helps save electricity and mitigate the plant’s power press, and has limited impact on the existing production system.
