摘要
本文通过对河南电网15座变电站内变压器、高压电抗器、带电构架及站界的可听噪声进行调查分析,通过研究得出了变电站的主要噪声源为主变压器,站内声源的噪声主频段为中低频,同时分析了不同电压等级变压器产生噪声的特点,提出了噪声综合治理方法。
Based on diagnosing transformers,h.t reactors,charged framework and the station circles the audible noise of the Henan Power Grid 15 substation,the article obtained the main noise source in substation is main transformerand the main source of the noise spectrum is the low-frequency by studying,and analyzes characteristic of the different voltage transformer produce noise,it was proposed comprehensive approach noise.
