Study on Harmonic Response Analysis and Vibration Reduction of Amorphous Metal Alloy Transformer

Because of the superior characteristics in no- load current and losses, using an amorphous metal alloy material in distribution transformers has become desirable over Oriented Silicon-Steel Distribution Transformers (OSDT). It may be difficult to reduce the vibration produced by an Amorphous Metal Distribution Transformer (AMDT), and notably the vibration of the core induced through the magnetostriction. To understand the study of AMDT core vibration, this paper provides diverse approach on study of the vibration characteristics on the single-phase SCBH 15-200/10 AMDT core. During this study, modal analysis of an AMDT core is carried out in ANSYS. The vibration modes are observed and analyzed which offer a complete representation of distortions stirring. A stimulating frequency series of 30-600 Hz has been settled the run the harmonic response simulation. From the outcomes shown in a graphic plan, the methods by tying up different sizes of foam rubber, and masses on the upper core to control the high vibration section was projected. A quivering measurement program was settled to accumulate the vibration signals. Viability and rationality of the suggested approaches have been confirmed via the testing setup, and the fitting mass pressure mounted on the top core was determined, providing an orientation for suppressing the vibration.
