FIELD: engines and pumps. ^ SUBSTANCE: proposed system comprises storage battery, device to disconnected the latter from onboard circuit, electric starter, starting contactor terminals, capacitive power accumulator made up of capacitors interconnected in series or in parallel. Charge circuit of said power accumulator comprises current-limiting resistor and diode to shunt said resistor. System includes also additional contactor with closing contacts to connect storage battery with said capacitive power accumulator prior to starting locomotive diesel engine, contactor with closing contacts, transducers of accumulator charge current and voltage, controlled rectifier of accumulator charge, unit to generate and indicate charge voltage, and pulse-phase control unit. Said accumulator is connected to controlled rectifier output via contactor with closing contacts. Rectifier power input is connected to charge generator output. Voltage transducer is connected parallel with power accumulator. Outputs of current and voltage transducers are connected with voltage generation unit input and indication unit input. Output of voltage generation unit is connected to pulse-phase control unit with its output connected to control input of controlled rectifier. Capacitive power accumulator is charged automatically without interference of engine crew after starting of locomotive diesel. Charge indication unit allows visual control over charge current and voltage. ^ EFFECT: higher reliability and longer life, automated charging. ^ 1 dwg |
