Description
Technical field
The utility model relates to a kind of synchronous motor full power test unit, belongs to technical field of motors.
Background technology
Existing synchronous motor test mostly is delivery test, with the aerogenerator is example, can only make no-load test if drag the 1.5MW generator with the 750kW motor, the version of testing table be with the 750kW motor mounting on support of motor, 1.5MW generator is installed on the generator bearing, the centre connects with cased muff coupling.In order to test generator performance more all sidedly, need carry out the full power type approval test, comprise no-load test, overspeed test, load test, temperature rise test, efficient and power factor test etc.The way that adopts is for to carry out mechanical connection with a dragging motor and tested generator at present, and the capacity of electronic side will equate with tested motor at least at full load.For carrying out large-scale generator test, the cost of making a dragging motor identical with tested generator simultaneously is than higher, also need the long cycle, and two motors connect by mechanical shaft joint, the machinery assembling is difficulty relatively, and the improper motor that also can cause of machinery assembling produces serious problems such as vibration, distortion, thereby influences finishing of whole test when carrying out test such as load.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the shortcoming that existing motor test must rely on the dragging motor of a constant volume or same capability, finish simultaneously tested motor properties test all sidedly, comprise no-load test, overspeed test, load test, temperature rise test, efficient and power factor test, a kind of synchronous motor full power test unit now is provided.
Device of the present utility model comprises a synchronous motor, two cover current transformers and 2,4 ... 2n overlaps winding, and wherein 2,4 ... 2n cover winding overlap respectively that phase differential is zero between winding. Synchronous motor 1,2,3...n cover winding are connected with the output terminal of the first cover current transformer as the winding that drags (being electronic side winding), with synchronous motor in addition 1,2,3...n cover winding connects with second input end that overlaps current transformer as the winding (side of promptly generating electricity winding) of generating, the output terminal of the second cover current transformer connects the input end of the first cover current transformer, the current feedback of the second cover current transformer output overlaps current transformer to first, thereby forms whole current return.Because the phase differential of electronic side 1,2,3...n cover winding and generating side 1,2,3...n cover winding is a zero degree, that is to say that every cover winding is mechanically independent substantially, therefore the armature reaction of electronic side 1,2,3...n cover winding does not have influence substantially to the main field of generating side 1,2,3...n cover winding, and every cover winding can separately operate under the different states.The general power of motor be electronic side 1,2,3...n cover winding and generating side 1,2,3...n cover winding and.
Needing two same capability motors and two cover current transformers to produce by the needed rated current of measured motor with the test of traditional synchronous motor compares, needed rated current of the utility model and voltage are all produced by a motor, and it just can realize the full power operation of motor with a generator and two cover frequency converters.The utility model is simple in structure, reliable, and cost is low, and energy-saving effect is obvious, is particularly suitable for the test to large-scale many cover winding synchronous motors.
