我局所属某水电广,装有混流卧式水轮发电机组四台,总容量为6400千瓦,各配有ХΓ—600型调速器一台。1983年8月2号上午10时,该电厂3号机组以单机运行的方式向地区35千伏变电所供电,由于是星期天,机组所带有功负荷只有500千瓦。转速(?)000转/分,频率、电压均为额定。调速器运行方式为自动调节(即手动自动切换阀在自动位置上),开度限制指针(红)在95%处。导水叶开度指针(黑)在3(?)%,变速机构指针在13%处,接力器手轮全部退出。此时,外部负荷基本无变化,机组及调速器均在稳定
My bureau belongs to a hydropower Canton, equipped with Francis horizontal hydroelectric generating sets four, a total capacity of 6400 kilowatts, each with a ХΓ-600 governor. On August 2, 1983, at 10:00 a.m., Unit 3 of the power plant supplied electricity to 35kV substations in a single operation. Since it was a Sunday, the unit had a power load of only 500 kilowatts. Speed (?) 000 r / min, frequency, voltage are rated. Governor operation mode is automatic adjustment (manual automatic switching valve in automatic position), opening limit pointer (red) at 95%. Water guide leaf opening pointer (black) at 3 (?)%, 13% of the gear mechanism pointer, the relay handwheel all exit. At this point, the external load is basically no change, unit and governor are stable
