一、30万千瓦汽轮机的空负荷试车 1983年7月,30万千瓦汽轮机开始进行厂内试车台位上的空负荷试车。8月18日首次冲转后,汽轮机总共启动5次。9月29日第5次启动时,机组转速升到3000转/分,并在空负荷情况下稳定运行。接着11月2日汽轮机又一次在空负荷下稳定运行。最后,11月17日通过了出厂试车的国家鉴定。 这样容量等级的大型汽轮机在厂内试车台位上进行空负荷试车,在我国尚属首次,世界上也只有少数国家能够进行。因此,这次试车成功,既证明了30万千瓦汽轮机的制造安装质量和启动性能是良好的,同时也为 First, 300,000 kilowatts turbine idle load test In July 1983, 300,000 kilowatts steam turbine began to test the site of the empty load test run. After the first divestment on August 18, the turbine was started a total of five times. The fifth start on September 29, the unit speed rose to 3000 rev / min, and stable operation under no-load conditions. Then again on November 2 the turbine ran steadily under empty load. Finally, on November 17 passed the factory test of the national appraisal. Large-capacity steam turbines of this capacity level are tested for empty load on the test bench in the factory for the first time in our country and only a few countries in the world can carry out the test. Therefore, the successful test run not only proved that the manufacture and installation quality and start-up performance of the 300MW turbine are good, but also
