解读国家标准《轨道交通有人环境中电子和电气设备产生的磁场强度测量方法》

Interpretation of National Standard Measurement Procedures of Magnetic Field Levels Generated by Electronic and Electrical Apparatus in the Railway Environment with Respect to Human Exposure

介绍GB/T 32577—2016《轨道交通有人环境中电子和电气设备产生的磁场强度测量方法》制定的背景、适用范围和主要内容。在综合分析国内外相关标准和实际测量数据的基础上,GB/T 32577—2016提出了动车组车厢内低频磁场的测量方法,为动车组、城轨车辆等磁场测试提供了依据,从而使测试结果具备可比性及重复性。

The article introduces the background, scope of application and main contents of GB/T 32577—2016 Measurement Procedures of Magnetic Field Levels Generated by Electronic and Electrical Apparatus in the Railway Environment with Respect to Human Exposure. Based on a generalized analysis of relevant domestic and foreign standards as well as actual measured data,GB/T 32577—2016 puts forward the approach to measure the low-frequency magnetic field in EMU compartments,which provides the basis for magnetic field tests on EMUs,urban rail vehicles and so on,thus making the test results commeasurable and repeatable.
