摘要
详细介绍了大型电力变压器铁心、油箱及冷却系统的噪声控制措施，指出只要采用合理的技术措施，就能使铁心振动噪声降低５～１０ｄＢ（Ａ），使变压器空气传播途中的噪声降低１０～２０ｄＢ（Ａ），并能使冷却系统的噪声接近本体噪声水平。
The measures on noise control of core, tank and cooling sysytem in large power transformer are introduced. The paper points that if the proper technical measures are adopted, the core vibration noise level can be reduced by 5～10dB(A), noise level along air path transmission can be reduced by 10～20dB(A), and the noise of cooling system can approach to its own body's noise level.
