摘　　要：大型汽轮机顺序阀方式投运时可能会出现诸多异常现象,它们的存在威胁着机组的安全运行。从3个方面扼要地总结了顺序阀方式投运时出现异常现象的原因,提出了在顺序阀方式正式投运前要进行顺序阀方式投运试验,该试验共包括6项子试验,都一一对此进行了详细阐述。应用实例表明,大型汽轮机顺序阀方式投运试验能提早暴露顺序阀投运过程中的众多问题,确保顺序阀方式投运过程的安全。Many abnormities are likely to happen when steam turbine sequence valve operation（SVO） mode is put into use, which threaten the security of steam turbine. This paper compendiously summarizes the reasons for these abnormities from three aspects, points out it is prerequisite to have a test before the SVO mode is put into application, and the test comprises six sub-tests, which are detailed one by on. One application example indicates testing for steam turbine SVO mode can undress many abnormities ahead of time, and insure the security.
