试论大型电力变压器的技术革新

On the Technical Innovation of Large Power Transformers

大型电力变压器的制造技术革新是国家经济社会发展的迫切要求,其既能降低变压器的损耗和噪声,又不会过分增加原材料消耗,还能保证大型变压器具有高可靠性、低温升、低局放、无渗油、低噪声的技术特点,在节能、环保和安全上具有重要意义。

The large-scale technology innovation of power transformer manufacturing is an urgent requirement of the national economic and social development. The paper states that the technology innovation can not only reduce the transformer＇s loss and noise without excessive increase in raw material consumption, but also can ensure the large transformer with the technical features, such as, high reliability, low temperature raise, low PD, no oil leakage and low noise. It has great significance on energy saving, environmental protection and engineering safety.
