摘要

为了研究温度和湿度对特高压直流输电线路可听噪声的影响，搭建了一个微型电晕笼，放置在一个温湿度可控的人工环境室内。同时，还建立了一套由空调加权网络声噪声计和8khz声传感器组成的声噪声性能测量系统。在微型电晕笼中测量了铜线在30% ~ 95%的不同湿度和0℃~ 30℃的不同温度下产生的可听噪声。已观察到可听噪声水平与温度和湿度之间的关系。

The Effect of Temperature and Humidity on Audible Noise Generated from UHV DC Transmission Lines

To research the effect of temperature and humidity on audible noise generated from UHV DC transmission lines, a mini corona cage has been constructed and put in a manual environment room, which temperature and humidity can be controlled. At the same time, an audible noise performance measuring system by using A/C weighted network audible noise meter and 8 kHz acoustic sensor have been set up too. The audible noise generated from a copper line have been measured in a mini corona cage not only at different humidity from 30% to 95% but also at different temperature from 0degC to 30degC. The relationship between audible noise level and temperature and humidity have been observed.
