《电力建设施工及验收技术规范》汽轮机组篇中关于超速的 9.9.6 .5条规定 :汽轮机超速时应适当关小电动主汽门 ,防止发生过高超速。通过对某电厂超速试验情况进行理论分析和数学模型的计算 ,说明关小主汽门如果应用不当 ,反而会引起超速。因此建议 9.9.6 .5条规定应该取消 ,以防止实际操作中因失误而引起事故。
Technical Specifications for Construction and Acceptance of Electric Power Construction The article 9.9.6.5 of the Turbine Corollary on Overspeed stipulates that when the turbine is over speeding, the main steam gate should be properly closed to prevent over-speeding. Through the theoretical analysis of a speeding test of a power plant and the calculation of the mathematical model, it shows that if the main valve of the main valve is not properly used, it will cause speeding. Therefore, it is suggested that Article 9.9.6.5 should be eliminated to prevent accidents caused by mistakes in actual operation.
