摘　　要：分析了冲管参数和冲管系统接入位置对汽水管道系统的安全性影响。以某新建电厂亚临界600MW机组冲管为例,分析了冲管时影响汽水管道系统安全性的主要因素,提出了解决以及降低影响汽水管道安全性的方法。通过以上实例,归纳出机组冲管整个过程需注意的问题,从而提高电厂汽水管道系统的安全性。The security influence of the flushing pipe parameter and the flushing pipe system on-position for steam-water piping system are analyzed. Taking a new build certain subcritical unit flushing pipe as an example, the main factors influencing the security of steam-water piping are analyzed. The methods of solving and reducing the influence of the security of steam-water piping are provided. Through the medium of above example, the noticeable problems during the wholly course of the unit flushing pipe are induced. Thus steam-water piping system security of the power station is advanced.
