标准摘要
[中文适用范围]: 本部分 IEC 60034(技术规范)提供了以下方面的共同基础: - 测量技术和仪器; - 安装布置; - 归一化和灵敏度评估; - 测量程序; - 噪声抑制; - 结果记录; - 结果解释; 针对额定电压为 3 kV 及以上的旋转电机定子绕组绝缘的在线局部放电测量。本技术规范涵盖检测电气局部放电信号的局部放电测量系统和方法。相同的测量设备和程序也可用于检测电气火花和电弧现象。 注:在线测量与离线测量的主要区别在于绕组上的电压分布不同,以及与运行相关的各种热和机械效应,如振动、接触电弧或定子铜与定子铁芯之间的温度梯度。此外,特别是对于氢气冷却的电机,离线和在线局部放电测量的气体和气体压力也不同。 [外文原描述]: IEC/TS 60034-27-2:2012(E) provides a common basis for: - measuring techniques and instruments; - the arrangement of the installation; - normalization and sensitivity assessment; - measuring procedures; - noise reduction; - the documentation of results; - the interpretation of results with respect to partial discharge on-line measurements on the stator winding insulation of non-converter driven rotating electrical machines with rated voltage of 3 kV and up. Keywords: rotating electrical machines
