上海电机厂为丰滿水电站試制成功了我国最大的一台60000瓩水輪发电机。这台水轮发电机是由四万五千多个部件組成的,需要的材料又大又复杂。最大的部件有70多吨重,最小的只有鉄丝那么細。机组定子外徑9.5公尺,內徑7.5公尺,总重1420吨;其中硅鋼片就有76吨;大轴长9.6公尺,法兰直徑1.66公尺,重45吨多。
The Shanghai Electric Machinery Factory succeeded in trial production of the Fengman Hydropower Station and succeeded in building China’s largest 60,000-unit hydroelectric generator. The hydro-generator is made up of more than 45,000 components and the materials required are large and complex. The largest part has more than 70 tons of weight, and the smallest is only as thin as the silk. The unit’s stator has an outer diameter of 9.5 meters, an inner diameter of 7.5 meters and a total weight of 1,420 tons. The silicon steel sheet has 76 tons; the large shaft has a length of 9.6 meters, the flange diameter is 1.66 meters, and the weight is more than 45 tons.
