Abstract:
The article considers the ways of points transmission to mounting horizons in the process of equipment assembly on the example of heat deformation determination in system "turbogenerator– foundation–ground" (TFG). Main attention is paid to providing required accuracy of measurements. The determination of heat deformations, considered in the article, is caused by the necessity for calculation (on the basis of geodetic data) of shaft line decentering values for their further installation during the process of assembling or reparing a turbogenerator. The article proposes several measurement methods for point transmission, which use high-precision total station and geodetic level. It gives the results of experimental measurements, carried out by the suggested methods. The use of high-precision devices for heat deformation detection of TFG system makes the point transmission process significantly easier, decreases the influence of main error sources and, if required, performs automatic monitoring of column length with a chosen time interval.
