提高树脂浇注干式变压器承受短路能力的措施

Measures for the Improvement on Ability to Withstand Short-Circuit of Cast-Resin Dry-Type Transformer

分析了树脂浇注干式变压器短路时内外绕组产生应力的机理及其后果。介绍了提高树脂浇注干式变压器承受短路能力的措施，并以实际产品为例表明这些措施的有效性。

The mechanism of stresses generating in internal and external windings and its consequence are analyzed in this paper. The measures for the improvement on ability to withstand short-circuit of cast-resin dry-type transformer are introduced, and the effectivness can be shown by taking a real product example when having taken these measures in this product.
