摘要

为深入研究变压器的噪声特性

设计并搭建了一套10 kV多工况变压器噪声测试系统。文中在分析变压器振动和噪声特性基础上

进行了测试系统电气设计和半消声室设计。通过在低压侧设置水冷有功可调负载、可调电感负载、短路开关、以及谐波发生器实现变压器多工况运行

根据变压器的噪声特性设计了半消声室性能实现变压器噪声的准确测量。利用该系统测试了一台10 kV变压器在短路、空载、负载、三相不平衡、谐波几种典型工况下的噪声

验证了系统的可靠性。

Abstract

A 10 kV transformer noise test system for multiple working conditions was designed and built to study the transformer noise characteristics. Firstly

the vibration and noise characteristics of the transformer were analyzed

and then the electric circuit and semi-anechoic chamber were designed. Water-cooled adjustable load

adjustable inductance

short-circuit switch

and harmonic generator were arranged on the secondary winding side of the transformer to realize its operation in multiple working conditions. The parameter of the semi-anechoic chamber was designed according to the noise characteristics of the transformer. Finally

the noises of a 10 kV transformer in several typical working conditions of such as short-circuit

no-load

three-phase power imbalance

and harmonic component were measured successfully

which proves the reliability of this test system.
