变电站环境噪声现场测试分析讨论

城市中变电站环境噪声测量对控制和防治环境噪声污染起着重要作用.由于变电站环境噪声现场测试受外界因素影响比较大,要提高其准确性,不仅要熟悉所使用的声级计的技术特性,在测量时还要考虑实际地理环境的影响.鉴此,介绍了使用声级计测量变电站环境噪声的情况,并对在现场如何提高测量的准确度进行了探讨.最后,通过在某变电站的测试实例,介绍了具体的测点布置和正确使用声级计的方法.

Analysis and discussion on field measurement of substation ambient noise

The ambient noise measurement for substations in the city plays an important role in controlling and preventing ambient noise pollution.As the field measurement of substation ambient noise is greatly affected by external factors,the improvement on the measurement accuracy necessitates not only familiarity with the technical features of the sound level meter used but also consideration of the effects of actual geographical environment.This paper describes the application of the sound level meter in measuring substation ambient noise,and makes a discussion on how to improve the field measurement accuracy.Finally,the specific layout of measuring points and the correct application means of sound level meters are introduced in combination with the measurement case in a substation.
