标准范围

IEC 60404-17:20 21适用于IEC 60404-8-7中规定的晶粒取向电工钢带和板材，用于在施加的50 Hz或60 Hz交流磁场下测量磁致伸缩特性。本文件定义了借助于单片测试仪和光学传感器测量晶粒取向电工钢带和薄板的磁致伸缩特性的一般原理和技术细节。本文件适用于以下各项的测量:蝴蝶环；峰峰值λ p-p；零峰值λ 0-p。磁致伸缩特性是针对正弦感应次级电压、针对磁极化的指定峰值和在指定磁化频率下确定的。

IEC 60404-17:2021 is applicable to grain-oriented electrical steel strip and sheet specified in IEC 60404-8-7 for the measurement of magnetostriction characteristics under an applied AC magnetic field at 50 Hz or 60 Hz.
This document defines the general principles and technical details of the measurement of magnetostriction characteristics of grain-oriented electrical steel strip and sheet by means of a single sheet tester and an optical sensor.
This document is applicable to the measurement of:

• the butterfly loop;
• the peak-to-peak value λp-p;
• the zero-to-peak value λ0-p.

The magnetostriction characteristics are determined for a sinusoidal induced secondary voltage, for a specified peak value of the magnetic polarization and at a specified magnetizing frequency.
