Title:
TANK FOR LARGE CAPACITY TRANSFORMER
Document Type and Number:
Japanese Patent JPS5843504
Kind Code:
A
Abstract:
Tank side walls (6) in very large transformers are normally screened by screening walls (9) from the stray flux produced by the windings (2) and (3). According to the invention, the screening walls (9) are supported on the tank side walls (6) via large-area compressible intermediate layers (10) and at the same time represent insulating walls for reducing the noise emission, since the natural frequency of the vibrating systems, consisting in each case of the parts of the screening walls (9) located between the attachment points and the associated parts of the intermediate layer (10), is less than 0.7 times the mains frequency. The use of this arrangement is particularly economically applicable in high-power transformers.
