Abstract
PURPOSE: To contral the vibration of an oil-filled electric machine accurately in a short time by means of a simple structure, by turning an adjusting nut of a tension device and adjusting the distance between reinforcing stays, when the resonant frequency of a side plate is tuned to the exciting oscillation.
CONSTITUTION: Tank 1 consists of side plate 2 and a plurality of reinforcing stays 3 welded on side plate 2. After an oil-filled electric machine is installed at the site, the resonant frequency of each part of side plate 2 is measured by means of a simple percussion test. If the results of the test showed that the resonant frequency of side plat 2 surrounded by stays 3 is tuned to the exciting oscillation, adjusting nut 10 of tension device 12 is turned and thereby the distance between stays 3 is adjusted. By this it is possible to adjust the vibration of an oil-filled electric machine accurately in a short time by a simple structure.
