摘要

蒸汽发生器(SG)二次侧水位的精确测量对核电站一、二次回路的安全稳定运行起着至关重要的作用。为了研究将磁致伸缩液位计应用于 SG 水位测量的可行性,我们获得了磁致伸缩液位计在稳定和瞬态条件下的测量结果,并与传统的压差式液位计进行了比较。结果表明,磁致伸缩液位计在冷稳态、热稳态和瞬态加压条件下均具有良好的测量精度。浮子的设计参数和操作参数是修正磁致伸缩液位计测量结果的必要条件。瞬态减压条件下的测量结果受到容器内流体运动的影响,导致测量精度下降。结果表明,磁致伸缩液位计具有用于核电站 SG 水位测量的潜力。

Research on magnetostrictive liquid level gauge for water level measurement of steam generator
The accurate measurement of the water level on the secondary side of the steam generator (SG) plays a crucial role in the safe and stable operation of the primary and secondary circuits of the nuclear power plant. In order to study the feasibility of applying the magnetostrictive liquid level gauge to the water level measurement of SG, the measurement results of the magnetostrictive liquid level gauge under the steady and transient conditions were obtained and compared with the traditional differential pressure liquid level gauge. The results indicated that the magnetostrictive liquid level gauge had good measurement accuracy under the cold-steady condition, thermal-steady condition and transient pressurization condition. The design parameters of float and operating parameters were necessary to correct the measurement results of magnetostrictive water level gauge. The measurement results under the transient depressurization condition were affected by the fluid movement in the container, resulting in a decrease in measurement accuracy. The results indicated that the magnetostrictive liquid level gauge had the potential to be used for water level measurement of SG in nuclear power plant.
