变配电所噪声变配电所噪声transformer and distribution substation noiseb一onPeldronsuo zoosheng变配电所嗓声(transformer and distributionsubstation noise)变配电所电气设备及其附属设备在运行中产生的可听噪声。110kV及以下的配电变电所噪声主要是电力变压器本体及其冷却系统产生的电磁性、机械性和空气动力性噪声。在220kV及以上的变电所中，除了变压器噪声外，不同结构型式的电执器和同步调相机在运行中会发生不同的噪声;空气断路器在操作时，由于压缩空气的排放，也会发出巨大噪声。高压配电装置导电部分及导线附近的空气在强电场中会产生电晕放电，发出噪声(见愉电线路可听噪声);高压配电装置中某些电场较集中部位，在空气湿度较高时，产生局部火花放电，也会发出噪声。电力变压器嗓声产生机理油浸自冷式电力变压器的噪声，是由其铁芯硅钢片的磁致伸缩振动和磁动态振动引起的电磁性噪声。磁致伸缩振动是由于铁芯励磁时沿着磁力线方向的硅钢片长度要增加，而垂直于磁力线的硅钢片宽度要缩小而引起的。由于硅钢片的各向异性，在磁通转向区内磁致伸缩振动现象更为明显。所以磁致伸缩振动与铁芯的尺寸和重量、铁芯角部的接缝形式等因素有关，细高的铁芯比粗矮的铁芯噪声低，轻的铁芯比重的铁芯噪声低，铁芯角部斜接缝的比直接缝的噪声低。磁动态展动是铁芯中间隙附近硅钢片之间的磁相互作用而引起的，因此它与铁芯装配时硅钢片上的压力、硅钢片的波浪度等因素有关.理想的条件是压力在0.08~0.12 MPa范围内，芯柱的不平整度小于0.2%。采用优质冷轧硅钢片，合理的铁芯结构，完善的制造工艺以及适当的防振措施，可使变压器嗓声有所降低。油浸风冷式或强迫油循环风冷式电力变压器，除了电磁性噪声外，还有风机产生的旋转噪声和涡流噪声，以及油泵产生的液力噪声。采用降低转速和优化风扇叶片设计，可以降低风机的噪声。对于油泵，除降低转速外，常采取选用精密级轴承、清除油中杂质和防止空气渗人等措施降低噪声。电力变压导噪声的声压级和翔谱声压级岛二20x坛(P/P0)dB，其中户为待侧声压，P0为基准声压。电力变压器容t大的，声压级亦大。通常，变压器嗓声的大小用A网络侧得的声级来代表，以dB(A)为单位表示.容t为6300 kVA及以下的中小型电力变压器声级为50~65 dB(A).容t为6300 kVA以上的大型电力变压器则为70~90dB(A)，电磁性噪声的频谱为100~500 Hz。大型电力变压器以100~200 Hz为主.中小型电力变压器则以200~300H:为主。
