墨西哥格雷佳尔伐河(Grijalva river)总体开发计划的第三期工程契可僧(Chicoasen)水电站将于1980年底正式落成。其最大的5台同步水电机组——ASEA 机组已由瑞典提供,即将安装竣工。该机组单机额定特性值为:容量31.6万仟伏安,每分钟164转,功率因数0.95,电压17仟伏,频率60赫芝;转子直径9.8米,重527吨;定子外径12.5米,重370吨;每台发电机配法兰西斯立轴水轮机,额定流量189立方米/秒,额定水头180米。契可僧堆石坝高245米,为拉丁美洲高坝之最,世界第6高坝,坝之总体积为1,450万立方米,水库总库容为16.8亿立方米。
The third phase of the overall development of the Grijalva river in Mexico will be completed by the end of 1980 at the Chicoasen station. Its largest five synchronized hydropower units - theASEA unit has been provided by Sweden, is about to complete the installation. The stand-alone rated characteristic value of this unit is: 316,000 volt-ampere capacity, 164 revolutions per minute, the power factor is 0.95, the voltage is 17 thousand volts, the frequency is 60 Hertz; The rotor diameter is 9.8 meters and the weight is 527 tons; 370 tons; each generator with Francis vertical shaft turbine, the rated flow of 189 cubic meters / second, the rated head of 180 meters. The cretaceous rockfill dam is 245 meters high, which is the highest dam in Latin America and the sixth highest in the world. The dam has a total volume of 14.5 million cubic meters and a total reservoir capacity of 1.68 billion cubic meters.
