The invention relates to electric generators, in particular to a three-phase synchronous main-auxiliary electric generator for a diesel-electric locomotive and aims to solve the problems that an electric generator system of an existing diesel-electric locomotive is relatively low in integration degree, has a complex mechanical system and is high in maintenance cost, low in locomotive space utilization rate and the like. Stators of the electric generator comprise a main electric generator stator and an auxiliary electric generator stator, an engine base of the main electric generator stator and an engine base of the auxiliary electric generator stator are in transitional fit through a spigot and connected together through bolts; two windings are embedded in a core of the auxiliary electric generator stator and embedded in the same groove and are independent systems; rotors of the electric generator comprise a main electric power generator rotor and an auxiliary electric power generator rotor, the main electric generator rotor and the auxiliary electric generator rotor are coaxially mounted, a winding excitation lead of the main electric generator rotor penetrates through a copper screw of a magnet yoke of the auxiliary electric generator rotor to be connected to a sliding ring on one side of the auxiliary electric generator rotor, and a winding excitation lead of the auxiliary electric generator rotor is directly connected to the sliding ring. The space utilization rate of the locomotive is increased, and the three-phase synchronous main-auxiliary electric generator is suitable for being driven at a high speed and can be well matched with the diesel-electric locomotive.
Description
technical field [0001] The invention relates to a generator, in particular to a three-phase synchronous main and auxiliary generator for an electric drive internal combustion locomotive. Background technique [0002] At present, the power supply of electric drive diesel locomotives mainly uses a high-speed diesel engine with a speed of 1800r / min to drive the generator system to supply power to each part of the locomotive (such as figure 1 As shown in the figure: 21-three-phase synchronous main generator, 22-coupling, 23-gear box, 24-three-phase synchronous auxiliary generator, 25-excitation generator). The generator system mainly has the following characteristics: 1. The generator system is composed of three independent generators: the three-phase synchronous main generator supplies power to the traction motor on the bogie to drive the locomotive; the three-phase synchronous auxiliary generator is the fan , cooling fan motor and other auxiliary motors provide power; the exc...
