FIELD: transport engineering. ^ SUBSTANCE: invention relates to methods of improvement of piston compressor plants. Shaft of compressor is connected with shaft of induction motor whose stator winding is connected to synchronous generator driven by shaft of heat engine, and rotor winding is connected through rectifier to armature winding of dc regulating machine whose field winding is connected with first control unit connected with first digital-analog converter connected to first output of microprocessor controller, with pneumatic system pressure transmitter being connected to first input through first analog-digital converter, and compressor shaft speed transmitter being connected to second input of microprocessor controller by means of second analog-digital converter. Second output of microprocessor controller is connected through digital-analog converter to control unit of contactor co0nnecting induction motor to synchronous generator, and third output of microprocessor controller is connected through third digital-analog converter with traction vehicle control unit. ^ EFFECT: provision of automatic maintenance of pressure in pneumatic system of traction vehicle irrespective of consumption of air, temperature and pressure of surrounding atmosphere. ^ 2 cl, 6 dwg |
