FIELD: transport engineering. ^ SUBSTANCE: invention relates to electrical equipment of variable furnished with air conditioners. Complex of both versions, contains two similar hinge-suspended three-phase generators of different bogies. Each generator has voltage regulator and V-belt drive. Generator load setter is provided. Upper branch of drive of generator at one of directions of car movement has maximum tension of V-belts between driven and drying pulleys of tensioning device. Setter is made in form of two units-generator phase alternation detectors, input of each of which being connected to phase winding of corresponding generator, and output, to automatic control unit. Inputs of automatic control unit are connected to current sensors, and outputs, to switches which control generators, rectifiers and power consumers in car. Generator phase windings are connected to rectifiers, and rectifiers and storage battery are connected in parallel to common buses of car through current sensors. Driving pulleys of V-belt drives are mounted in middle parts of axles of corresponding wheelsets. Moreover, according to first design version, driven pulleys are installed by one side relative to frames of three-phase generators rotated simultaneously in one direction in rotor tail parts. According to second design version, driving pulleys of V-belt drives are connected with driven pulleys installed on tail parts of rotors of three-phase generators by means of split V-belts. ^ EFFECT: enlarged possibility of mounting of generators under car, facilitated replacement of V-belts in flexible drive at wear. ^ 4 cl, 6 dwg |
