Abstract
The invention provides a steam turbine generator stator-rotator magnetic center measuring tool, which is characterized by comprising an angle square and a sliding block with a hole in the middle, wherein the sliding block is sleeved on the angle square through a hole and can slide on the angle square freely; and a positioning device positions the sliding block on the angle square through a positioning hole. The invention also provides a using method of the tool, which comprises the following steps that: after a rotor is transferred to a stator, the angle square is leaned against a protective ring of the rotor; the short edge of the angle square moves toward the inside of the iron core of the generator to prop up the step stopper of the iron core of the stator, so that the sliding block slides along the angle square, props up the outer side of the protective ring of the rotor and fastens the positioning device to fix the angle square and the sliding block; and the angle square is takenout, the distance from the sliding block to the tail end of the angle square is measured, the size of a steam end and the size of an excited end are compared, the axial position of the rotor is adjusted according to the difference, and when the difference is adjusted to a required range, the axial magnetic centers of the stator and rotor of the generator are aligned. In the invention, the problemof difficult positioning of the magnetic centers of the stator and rotor of the large-sized steam turbine generator is solved.
Description
Technical field
The present invention relates to a kind of steam turbine generator stator-rotator magnetic center survey instrument and method of application thereof, can make things convenient for generator stator-rotator relative axial position when confirming to install fast.
Background technology
Increase along with generator capacity; Its rotor physical dimension also increases relatively; Requirement to assembling is also increasingly high, considers that its output current is big, and original light instrument is difficult to the axial magnetic center of heavy-duty generator is measured and located; Therefore need a kind of instrument that can measure the magnetic center of large scale generator, also will improve the precision of measurement simultaneously.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can measure the instrument of large scale generator magnetic center and the method for application of this instrument.
In order to achieve the above object; A technical scheme of the present invention has provided a kind of steam turbine generator stator-rotator magnetic center survey instrument; It is characterized in that comprise angle square and the middle slide block that has the hole, slide block is through on the angle square through the hole and can on angle square, be free to slide; On angle square, have pilot hole, locating device is positioned at slide block on the angle square through pilot hole.
Another technical scheme of the present invention has provided the method for application of a kind of steam turbine generator stator-rotator magnetic center survey instrument, it is characterized in that, step is:
Step 4, angle square is taken out; Measure the distance of slide block to angle square tail end; The generator turbine end retaining ring end face of measuring is compared to distance unshakable in one's determination to distance unshakable in one's determination and generator turbine end retaining ring end face, carry out the adjustment of rotor axial position, carry out step 1 to step 4 after having adjusted again by difference; In difference is adjusted to claimed range, think generator stator-rotator axial magnetic center-aligned.
The invention solves the difficult problem in location at large turbo-type generator stator-rotator magnetic center; Have efficient, simple and practical, safe and reliable advantage concurrently; Can in the similar assembly structure of different product, promote the use of, be the technological equipment of survey instrument location, high-rating generator stator-rotator magnetic center.
