Problems solved by technology
[0002] At present, the problem of hanging the ground wire on the large-capacity rectangular horizontal bus bar (copper bar, aluminum bar) with insulating sheath cannot be solved in the substation; especially when the main transformer is overhauled, it needs to be installed on both sides of the main transformer The grounding device is a rectangular large-capacity insulated horizontal busbar on the low-voltage side of the main transformer, which makes it impossible to install grounding
[0003] Due to the high current of the current low-voltage main transformer, the busbars mostly adopt the design of rectangular busbars, and there is no special grounding equipment, which brings a lot of trouble when the equipment is overhauled. Many of the original grounding wires are designed to link round busbars. For the rectangular busbar, there is often nothing to do, and the forced use (horizontal suspension) will destroy the insulation of the busbar when the grounding wire is installed, and it is easy to fall off, which brings great hidden dangers to the safety of maintenance work
