摘要一战到底主持人:汽轮机监测保护系统是火电机组最重要的保护系统。机组在安装调试阶段时,往往会出现TSI评价人的词语系统参数异常。正确的完成TSI系统的现场安装和调试,是保障TSI系统准确测量、正确动作的先决条件。系统带电后,所有测点的测量通道都应指示出正确的测量参数。随着机组进入油循环和盘车,轴系位置发生了改变,TSI系统的参数输出也因此会发生明显的变化。机组启动后,由于机组各自不同的特性、安装水平等,TSI系统会输出各种各样的参数指示。当机组带负荷运行后,正常情况下,tfboys写真是抄袭于正吗轴位移、胀差、缸胀、轴振、偏心和瓦振的输出参数,会随机组负荷的变化呈缓慢变化趋势。分别在安装调试阶段、进油盘车阶段、启动阶段及正常带负荷运行阶段,对汽轮机监测保护系统的示值异常进行了分析和探讨。

Abstract:Turbine monitoring the electrical fire protection system is the most important group protection system。Commissioning Unit in the installation stage, they will appear abnormal TSI system parameters。TSI the right to complete the installation and commissioning at the scene, is to protect the TSI accurate measurement system, a prerequisite for correct action张碧晨男朋友。
Charged system, all measuring points of measurement channels should be directed to the correct measurement parameters。As the crew entered the oil circulation and set cars, shaft position has changed, TSI output parameters of the system will also result in significant changes。Unit is activated, because the characteristics of different units, the installation level, TSI will be a variety of parameters output instructions。When the unit-load operation, under normal circumstances, the axis displacement, the differential expansion, the expansion tank, the shaft vibration, eccentric and tile-output parameters, the group will be randomly load changes in the trend of slow change。Were installed in the debugging stage, into the oil-car stage, start-up phase and operational phase of the normal load, the turbine protection system of monitoring indicated abnormal were analyzed and discussed.
