Design and finite element analysis of a 15MVA transformer tank

MECHANICAL ENGINEERING

The present work is a customized design of a transformer tank as per the specification given by the industrial manufacturer. The objective of present work is to design transformer tank and the modification is carried out in order to improve strength to weight ratio of transformer tank. Transformer tank size is large and having the weight of several tones (without coil assembly and oil). The housing of a transformer comprises of various compartments fabricated from mild steel plates. Loaded transformer housing is subjected to its own weight plus coils and oil. Hence, Reduction in weight keeping the required strength for application will obviously result in to cost saving. The size of transformer tank is large and having the weight of 4 ton approx. (without coil assembly and oil) which is usually elevated at certain height from ground level. The housing contains coil assembly and the oil. The total weight of such transformer is 32 ton which include weight of oil, coil and core assembly, conservator, radiator etc. Large capacity of transformers tanks can weigh to several hundred tons. Strength and rigidity are the important criteria of design. Hence it is necessary to evaluate existing design to improve strength to weight ratio and similar strategy can be applied to other size of transformer to reduce weight.
