漫湾电厂一期共五台水轮发电机组,配置电气过速保护功能。当调速器系统及计算机监控系统操作电源消失时,存在机组过速、飞逸的风险,为了确保机组运行安全,电厂对机组加装纯机械过速保护装置,通过试验,纯机械过速保护装置能在操作系统电源消失等极端情况下,准确动作,限制机组转速,为电厂安全生产提供坚强保障。
Manwan a total of five power plants a hydroelectric generating units, configure the electrical over-speed protection. When the governor system and computer monitoring system power supply disappears, there is the risk of over speeding and fleeting. To ensure the safe operation of the unit, the power plant installs a pure mechanical over-speed protection device to the unit. Through tests, pure mechanical over-speed protection Device in the operating system power loss and other extreme cases, accurate action, limit unit speed, power plant safety and provide a strong guarantee.
