A range-extended electric vehicle gas turbine generator

Abstract

The invention discloses an extended-range electric vehicle gas turbine generator and belongs to the field of electric engineering. The extended-range electric vehicle gas turbine generator comprises stationary blade grids, movable blade grids, an excitation iron core, an exciting winding, a shaft, a rotor core, an armature core, an armature winding and a motor housing. The extended-range electricvehicle gas turbine generator is characterized in that fuel gas flows through the stationary blade grids and then pushes the movable blade grids and the rotor core rotate around the shaft; the excitation iron core is arranged on one side of the rotor core, and the armature core is arranged on the other side of the rotor core; a plurality of uniformly distributed fan-shaped through holes are formedin the circumference of the rotor core; a plurality of exciting poles protruding towards one side of the rotor core are uniformly distributed in the circumferential direction of the excitation iron core, and a plurality of armature poles protruding towards one side of the rotor core are uniformly distributed in the circumferential direction of the armature core. The extended-range electric vehicle gas turbine generator can fully play the advantage that the power generation efficiency of the gas turbine generator is higher than that of a power generator driven by an internal combustion engine.The rotational inertia of the rotor core is small, and the rotor core can rotate at high speed and thus is very suitable for the extended-range electric vehicle gas turbine generator.

Description

technical field [0001] The utility model relates to a gas turbine generator for an extended-range electric vehicle, which belongs to the technical field of electric vehicle engineering. Background technique [0002] In view of the current insufficient battery life of pure electric vehicles, range-extended electric vehicles appear in the field of pure electric vehicles as a transitional technology. Compared with traditional electric vehicles, extended-range electric vehicles add a fuel engine, which effectively improves the problem of short cruising range of pure electric vehicles. After the electric vehicle travels for a certain mileage, when the battery power drops to the set value, the electric vehicle can be driven in Zeng mode through the generator set. [0003] Among the published patents, there are few patent applications related to Zeng Cheng electric vehicle generators. For example, the patent application number is 201210264800.5: a range-extending generator for an...
