GENERATOR STATOR INSTALLATION

摘要

An electrical generator section includes a case, a screen ring, first and second stator sections, and a rotor. The case has a plurality of circumferentially-spaced axial flow cooling air inlets, and first and second electrical connector ports. The screen ring is broken by a circumferential gap, and is secured over the cooling air inlets. The first stator section is heat-fitted into the case in a location axially forward of the screen ring, while the second stator section is heat-fitted into the case in a location axially aft of the screen ring. The first stator section is connected to the first electrical port through the circumferential gap, and the second stator section is connected to the second electrical port. The rotor is disposed radially inward of the first and second stator sections.

主权项

1. A method of assembly for a stator section of an air-cooled electrical generator having at least first and second stator assemblies, the method comprising:
aligning a screen ring having a circumferential gap with air passages of a generator case; affixing the screen ring to the case; heating the case above an installation temperature sufficient to enable heat-fitted stator installation; installing the first stator assembly axially forward of the screen ring, while the case is hot; passing wiring of the first stator assembly through the circumferential gap and a first connector ports; installing the second stator assembly axially aft of the screen ring, such that the screen ring is situated between the first and second stator assemblies, while the case is hot; and passing wiring of the second stator assembly through a second connector ports.
