However, since the main drive system and the auxiliary drive system share a main generator to provide energy, when the main drive system fails, for the safety of the locomotive, the main generator will stop outputting electric energy. Since the main generator has stopped outputting electric energy, this At this time, the auxiliary drive system will not receive power, which will cause the auxiliary drive system to lose power

An embodiment of the invention provides an internal combustion locomotive and a main-auxiliary transmission system thereof. The main-auxiliary transmission system comprises a locomotive internal combustion engine, a power generator, a main rectifier, a main intermediate direct-current loop, a main transmission system, an auxiliary converter, an auxiliary intermediate direct-current loop, an auxiliary transmission system, a power battery charging-discharging device and a power battery. When the main transmission system fails and the power generator stops sending out electricity, the power battery is used to power the auxiliary transmission system; it is guaranteed that the auxiliary transmission system can operate normally for a period of time when the main transmission system fails; time is gained for troubleshooting and recovery of the main transmission system.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of a diesel locomotive, in particular to a main and auxiliary transmission system of a diesel locomotive and a diesel locomotive. Background technique [0002] The electric drive system of a diesel locomotive is divided into two parts: the main drive system and the auxiliary drive system. The main drive system mainly provides energy for the traction motor, and the auxiliary drive system mainly provides energy for auxiliary systems such as ventilators, cooling fans, air compressors, and control circuits. [0003] in, figure 1 It is a schematic diagram of the internal combustion locomotive transmission system in the prior art, such as figure 1 As shown, the diesel locomotive is equipped with a main generator, and the main generator provides electrical energy for both the main drive system and the auxiliary drive system. However, since the main drive system and the auxiliary drive sy...
