Abstract

There are five physical elements of the transport sector
that can be changed to reduce emissions: Vehicle efficiency,
greenhouse gas intensity of the fuel used, level of transport
activity, mode of transport chosen, and amount of capacity used.
In this paper is described one practical example of the
replacement (reconstruction) of the active steel end zone of the
turbo-generator n.1 which operates in REK Bitola, with purpose
to improve the condition of the turbo-generator from magnetic
point of view during the modernization for increasing the power.
Turbo-generator is type TVV 200-2A produced by “Elektrosila”
– Russia. The stator winding is cooled directly with distilate. The
rotor winding, the stator core and the housing are cooled with
hydrogen. The reconstruction itself covers replacing more
elements which are:
Replacement of five end packs of each active steel end zone,
which are manufactured in monolithic (backed) version and with
successive reducing of its height
Reconstruction of the pressure rings with simultaneous
installation of new enlarged copper screen on the pressure rings
Additional fingers for better tightness and intensifying the
cooling of the end zones
Stabilization of the pressing tightness of turbo-generator core
active steel with installing special spring devices so called
pressure accumulators
During the realization of the reconstruction special tools, devices
and equipment have been used.
Also for all examination which have been done protocols (test
reports) have been made. Every test report consist from: test
object, basis, criteria of control, test results and conclusion on the
test results.
