关于发电机转子对地电压测量问题的探讨

Discussion on generator rotor voltage measurement

转子一向是发电机的重要部件,随着我国电力工业的发展,电力系统本身变得越来越庞大和复杂,为了确保发电厂的发电机组的可靠和经济地运行,保证转子的安全,如何防止和及时发现转子接地故障一直受到发电企业的广泛关注。今通过对两种不同冷却方式(包括双水内冷与空气循环风冷)的发电机转子对地电压测量问题的探讨,找出有效准确的测量方法,加强正常运行时对转子绝缘的监控。

Rotor has always been important parts of generators,With the development of electric power industry in China,Become increasingly large and complex power system itself,in order to ensure reliable and economic operation of power plant generators,guarantee the safety of the rotor,prevention and timely detection of rotor earth fault has been generating widespread concern in the enterprise.This on two different cooling methods（including dual air cycle air cooled and water cooled） problems of generator rotor voltage measurement,identifying effective and accurate method of measuring to strengthen normal run-time monitoring of rotor insulation.
