摘　　要：本文简要介绍汽轮収电机轴电压产生原因及危害、轴电压、轴电流测量的工作原理、功能、试验及应用等情冴。轮収电机轴电压轴电流在线监测装置能提供収电机轴电压和轴电流在线检测,及时収现过高的轴电压和轴电流,保证了収电机安全可靠运行。In this paper the causes and harmfulness of generator shaft voltage are briefly described, also the principle, structure composition, functions and tests for a kind of generator shaft voltage and current monitor are discussed. This monitor can provide online measuring of shaft voltage and current while a generator is operating, and prompt to take some actions in time when detecting high shaft voltage and harmful shaft current. This device is helpful to ensure the safe and reliable operation of a generator.
