摘要

针对某电厂法国ALSTOM公司制造的600MW机组汽轮机在冬季低压差胀过大影响机组安全经济运行的问题

对低压差胀探头前置器冷却和前置器温度特性进行了试验

认为冬季汽轮机低压差胀测量误差变大的主要原因是WL172A+AO-02-11C型低压差胀前置器质量不良

以及环境温度变化对其测量输出值影响显著。对此

对前置器进行移位后

冬季汽轮机低压差胀测量受环境温度影响程度明显改善

与同期相比其测量误差下降了10%。

Abstract

Directing against the problem of differential expansion in low-pressrue cylinder of 600 MW steam burbine manufactured by ALSTOM is far larger in the winter season

and affecting safe and economic operation of the unit

the probe of differential expansion in low-pressure cylinder

the cooling of prebox

and the temperature characters of prebox have been tested.It is believed that the main causes leading to large error in measurement of differential expansion of low-pressure cylinder in winter season are the bad quality of prebox WL172A+AO--02-11C used for measuring differential expansion in low-pressure cylinder

and the remarkable influence of ambient temperature variation upon the output value of measurement.For this

the position of prebox has been removed

making the influence of ambient temperature in winter season to be substantially reduced

compared with the value in same period

the error in measurement has decreased 10%.
