FIELD: railway transport; locomotive diesel engines.
SUBSTANCE: invention provides 100% use of energy of one or more capacitor gangs, reduction of magnetic flux at starting and increase of torque. For this purpose in locomotive diesel engine starting system implementing proposed combination method of electric starting contains starter-generator, generator-exciter mechanically coupled with shaft of armature of starter-generator and parallel-connected power supply sources in form of standard storage battery and capacitor gangs, and also device to control starting and sequence of connection of capacitor gangs. Aline with standard method of diesel engine starting from storage battery, provision is made for separate excitation of generator-exciter from storage battery and connection of its armature circuit to one of capacitor gangs. Moreover, in 2-3 sec after initial moment of starting, connection of separate winding of starter-generator to second capacitor gangs is provided. In process of diesel engine starting, capacitor gangs are disconnected from storage battery. In process of diesel engine starting disconnection of potentials of capacitor gangs and their connection to armature circuit of generator exciter and to separate winding of starter-generator and, after starting of diesel engine, connection of potentials of capacitor gangs to storage battery is provided by interlocking starting contactors.
EFFECT: provision of faultless starting of locomotive diesel engines.
