基于主振点定位的特高压变压器振动声功率测算方法

open access: yesGaoya dianqi
与声压法和声强法相比,振动声功率测算方法具有从变压器本体和风扇综合噪声中提取本体声源特性的优势。振动测点的布放方式对声功率测算结果影响较大。目前振动测点布放尚无统一标准,多采用近似均匀布放方式,声功率测算结果往往偏低。文中提出基于变压器箱体表面主振点定位的非均匀布点方法,对山西省内某1 000 kV特高压变压器的本体辐射声功率进行了测算研究。在测试条件下,新方法得到的本体振动声功率高于均匀布放方式,本体振动和风扇总声功率与声压法测算结果吻合度更高。该方法有利于提高特高压变压器本体声功率测算的准确度 ...
