Contacting Stability of Sliding Electrical Contacts

It is stated that the operation of sliding contact unit accompanied by vibrations brushes occur as a result internal and external mechanical influences. The resulting violations (SC) instability contacting lead to deterioration in quality current transmission, increased sparking, accelerated wear SC. article devoted derivation verification universal formulas for calculating relative factor (RIF) Derived allow RIF any SC compounds. Mathematical expressions are obtained determine distributions tangential axial directions transition layer An experimental stand studying various compounds at idle rated load mode described. cycle, which establishes correspondence between instantaneous value length measuring platform movement collector Expressions determining equivalent area different cases placing brush zone main derived. These us find regions on data based.
