标准范围
IEC 60076-10:20 16定义了声压和声强测量方法，根据这些方法确定变压器、电抗器及其相关冷却装置的声功率级。这些方法适用于IEC 60076和IEC 61378系列所涵盖的变压器、电抗器及其冷却装置（安装在变压器上或与变压器分离）。本标准主要适用于在工厂进行的测量。由于物体（包括其他变压器）的接近，现场条件可能会非常不同。然而，本标准尽可能适用于现场测量。与上一版相比，此版本包括以下重大技术变更:-引入了其他有用的定义；-为本标准而引入的配电型变压器的定义；-引入声级测量规范的新条款；-对配电变压器以外的变压器引入1/3倍频程测量的要求；-配电型变压器以外的变压器的标准测量距离由0.3米改为1米；-测量表面的高度现在被清楚地定义为从反射平面开始计数；-测量表面公式统一；-引入强度方法的校正标准；-介绍了干式反应堆的声音测量规则；-订正数字；-引入新的信息测试报告模板（附件B）；-IEC 60076-10-1（应用指南）同时修订，为本标准的使用提供了有价值的信息。
IEC 60076-10:2016 defines sound pressure and sound intensity measurement methods from which sound power levels of transformers, reactors and their associated cooling devices are determined. The methods are applicable to transformers, reactors and their cooling devices - either fitted to or separate from the transformer - as covered by the IEC 60076 and IEC 61378 series. This standard is primarily intended to apply to measurements made at the factory. Conditions on-site can be very different because of the proximity of objects, including other transformers. Nevertheless, this standard is applied to the extent possible for on site measurements. This edition includes the following significant technical changes with respect to the previous edition:
- additional useful definitions introduced;
- definition of distribution type transformers introduced for the purpose this standard;
- new clause for sound level measurement specification introduced;
- requirement for 1/3 octave band measurements introduced for transformers other than distribution type transformers;
- standard measurement distance changed from 0,3 m to 1 m for transformers other than distribution type transformers;
- height of measurement surface is now clearly defined to count from the reflecting plane;
- measurement surface formula unified;
- correction criteria for intensity method introduced;
- rules for sound measurements on dry-type reactors introduced;
- figures revised;
- new informative test report templates introduced (Annex B);
- IEC 60076-10-1 (application guide) revised in parallel providing worthwhile information for the use of this standard.
