FIELD: industrial electronics and electrical engineering; feeding mobile load from current- carrying busway. SUBSTANCE: current-collecting device that provides for feeding motor-car electrical equipment in the course of its assembly tests from current-carrying busway supplying electrical energy of different kinds has three-phase ac current collector, wiring box accommodating lead-in circuit breaker electrically connected to current collector and to load connector, flexible cable 5 joined to connector and fitted with clamps 6 for connecting motor-car electrical equipment, three-phase ac-to-dc voltage converter, as well as input and output voltage indicators. Converter is mounted in wiring box and uses pulse-type circuit arrangement with output voltage regulation and electronic overload protective gear. Each cable clamp has jaws with projection in the form of tetrahedral pyramid whose vortex faces other jaw wherein there is hole to receive mentioned projection. Input and output voltage indicators are disposed on side walls of wiring box, output voltage indicators being provided on both side walls for convenience. EFFECT: enlarged functional capabilities; facilitated servicing; reduced size and mass. 1 cl, 5 dwg
