Abstract
A hydraulic generator belongs to a generator driven by a hydraulic motor. The technical scheme adopted in the utility model is that an output shaft of the hydraulic motor is connected on a rotor shaft of the generator, and a shell of the hydraulic motor is fixedly connected with a shell of a stator of the generator. The hydraulic generator provided by the utility model has the advantages that a power system with a variable rotational speed is used for input and a power system with a constant rotational speed for output are adopted; and the AC generation of the generator is realized through that the hydraulic motor is used for driving a rotor of an AC generator, and a power system is controlled by the hydraulic motor under the constant current working condition to perform variable rotational speed running within a certain rotation speed range, so as to guarantee that the hydraulic motor drives the rotor of the AC generator to perform constant speed rotation within a certain constant rotational speed.
Description
Technical field
The utility model belongs to generator, particularly uses the generator of fluid motor-driven.
Background technology
Traditional alternating current generator all adopts the direct drawing generator rotor of dynamical system, and the dragging motor rotor constant speed rotation under constant rotational speed of control dynamical system, and cutting magnetic line generates electricity, and obtains the alternating current of a fixed frequency.This generator must rely on the constant rotational speed of dynamical system to guarantee the normal power generation of alternating current generator.In the running generating, all adopt DC generation at present, the mode of alternating current is provided after inversion, can not directly carry out alternative electric generation.
Summary of the invention
The purpose of this utility model just provides a kind of by the hydraulic motor-driving generator rotor, dynamical system variable speed when work in certain range of speeds, can guarantee the hydraulic generator of alternating current generator normal power generation.
The solution that realizes the utility model purpose is the output shaft 4 that is connected with hydraulic motor 2 on the armature spindle 3 of generator 1.
The stator casing of the shell of hydraulic motor 2 and generator 1 is connected.The armature spindle 3 of generator 1 is spline or shaft joint or singly-bound or two key or triple bond with output shaft 4 types of attachment of hydraulic motor 2.
The utility model has the advantages that the input of variable speed dynamical system, decide the output of rotating speed dynamical system.Rotor with the fluid motor-driven alternating current generator, dynamical system variable speed when work in certain range of speeds, constant current amount operating state control by hydraulic motor, guarantee that hydraulic motor drags alternator rotor and carries out the constant speed rotation under a certain constant rotational speed, realize the alternative electric generation of generator.
