Abstract
The utility model relates to a kind of gas turbine powered generator syndeton, comprise gas turbine rotor axle, shaft coupling, high speed permanent magnet motor rotor, described gas turbine rotor axle is provided with axial-flow turbine impeller and centrifugal compressor impeller, end is connected with one end of shaft coupling by spline, and the other end of shaft coupling is connected with the rotor of high-speed permanent magnet motor by spline.The utility model is simple and compact for structure, achieves the normal work of high-speed permanent magnet motor, and use reliable, after parts reduce, the dependability of system is improved, failure rate, manufacturing cost and maintenance cost all have obvious reduction.
Description
Technical field
The utility model relates to a kind of gas turbine powered generator syndeton.
Background technology
The general power of miniature gas turbine is between 18-200KW, the mode being forwarded motor output power by miniature gas turbine band is the new technology that development in recent years is got up, because micro-gas-turbine unit rotating speed is high, and the working speed of generator is very low, in order to meet the job requirement of generator, generation current machine is connected with syndeton many employings decelerator of gas turbine, i.e. Gas Turbine Power output connection reducer, and then the structure be connected with generator.Meanwhile, a starter motor also to be set, for starting gas turbine.This structure makes the mechanical structure of unit very complicated, and in the unit course of work, reliability is bad, and a large amount of power consumption is on mechanical transmission.Now succeed in developing the high-speed permanent magnet motor of miniature gas turbine, the working speed of this motor is 52000rpm, suitable with the output speed of gas turbine, therefore consider to adopt to cancel gear reducer mechanism mode, the output of gas turbine is directly connected with high-speed permanent magnet motor, and this mode there is no ripe technical scheme at present.
Summary of the invention
The purpose of this utility model is to provide a kind of Gas Turbine Generating Units armature spindle, and described armature spindle can realize directly connecting high-speed permanent magnet motor, does not need by gear reducer mechanism, reaches that structure is simple, good reliability, and the object that the loss of power is little.
The technical solution of the utility model is, gas turbine powered generator syndeton comprises gas turbine rotor axle, shaft coupling, high-speed permanent magnet motor, described gas turbine rotor axle is provided with axial-flow turbine impeller and centrifugal compressor impeller, end is connected with one end of shaft coupling by spline, and the other end of shaft coupling is connected with the rotor of high-speed permanent magnet motor by spline.
The utility model will arrange shaft coupling between gas turbine and high-speed permanent magnet motor, eliminate reducer structure, each parts are made to be positioned on same axis, make whole system structure simple, simultaneously, by shaft coupling directly by gas turbine and high-speed permanent magnet motor direct connection, directly produce electric power by motor.In addition, high-speed permanent magnet motor is directly connected with gas turbine, and when gas turbine starts, high-speed permanent magnet motor as startup power, can start gas turbine.The utility model is simple and compact for structure, achieves the normal work of high-speed permanent magnet motor, and use reliable, after parts reduce, the dependability of system is improved, failure rate, manufacturing cost and maintenance cost all have obvious reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
